Types of pump - Mahab.ir

A special pump or the electric motor has specs that power, RPM, maximum amps allowed, maximum load, frequency and voltage allowable power type single phase or three phase being is very important that these components can make the system protection for the good we choose.

About the pumps knowing the components such as voltage, allowable power, the type of Phase (single phase or three phase) and the maximum amps allowed, the type of fluid transferable and is also the minimum allowed height of importance to great ppt.

If the choice of the pump to suit the type of fluid, etc. fit with the existing power and also fit the height and the amount of capacity requested, etc., along with a system of protective fit to be chosen, etc., arguably, has never been to the fundamental problem of collision, will not, etc. that need major repairs, and general, remember this. for better use of capacity, the better to recommend proper Builder, be sure to notice.

Switchgear, protective suits, a sign that all items available in the special pump and motor to control, and there is the problem before damage to input power cut does. Switchgear, protective, electronic, alone or boards, normal, equipped with bi-metal and control the phase and control the time and ترموگارد can be electric motor or capacity you have insurance does.

All the items that cause the burning of an electric motor or the pump, be as follows:

Function no load or without water for a long time (according to the type and strength of 5 to 60دقیقه) causing losses, high, energy for heat and not having ترموگارد or overload, thermal, or, leaderboards, protective, electronic, winding it burns.
- In this case, the effect of the heat created all the insulation, furrows, dry, and brittle, or melted and شارلاک on the winding burned and lacquer plated wire, lacquered black, and according to the current power of the winding, the half-burner to body connection, and even unwinding electric motors creates.Having protection system, depending on the quality and accuracy, it damages your control.
- Note: in this mode, in the winding of the single phase., the winding main and winding, Bootstrap, and in a winding, three-phase, all phases, also the capacitor in the conditions of same, and have the heat created to all components of damages.
Imposed load (height unauthorized) and the transmission fluid more concentrated than the limit, causing pressure on the profiles of butterflies and on the effect of pulling the amp more than the allowed size, etc. winding is heated in the absence of system protective fit within a very short time, Burns and conditions on burning it in a short time more with spend less time wholly like undue burden and without water, work is only in this mode due to the higher temperature, copper etc. wire earlier than insulating burns.
- Note A: in the event of being forced to use the pump at a height less than the height of the non-permitted, to avoid the added burden can install a gate valve in the path of the pump, height, create a virtual and amp consumer in the limit of your set.
- Note two: in this case, in the special pump or the electric motor, the single phase capacitor permanently., the winding main earlier than bootstrap burns.
Hidden butterfly on the pump or malfunction, bearings and گیرپاژ out رتور cause increase in the AMP has been authorized, and in case of not having a system of protective suits spend less time than fluid viscous drag, etc. exactly the same about learn, burns, etc. in this case, due to the very high temperature, copper, etc. winding, much earlier than the insulation, the burns and the insulation is dry and brittle, are not. (Note: in this case, in the electric motor, the single phase capacitor permanent, etc. winding, bootstrap, earlier than winding main burns and the possibility of burning and deterioration of the capacitor, bootstrap winding is greater.)
In case of having the connection and short in the coil, the Winding, which, over time, the friendly Spark, xHamster connectors in reel to far spread, find and to browse amp consumer with the spread of these connections, etc. have gone up, and in case of not having a system of protective suits, domain impeccable, expand the vision, find and all reel in the atmosphere and lead to the burning of the complete pump to be.
Elongation of the cable, pump, and wounded it, or connect it to the body or to each other, wholly, causing the connection was short lived, and in case of not having a system, protective suits, etc., causing shock and spark intense that even the cause of the explosion and the damage serious to pump it, especially in capacity, three-phase, which connect the phase to phase to the centre of a dangerous, even hundreds of times amps consumption goes up and the possibility of the explosion of the items very much.
Hang a phase in the pump, three phase, for whatever reason, may or disconnect connectors, capacitors, pumps single problem into two face creates.
- If the pump in the beginning, is in the mode of the starter with the two phases being the power in the pump, three-phase or disconnect connectors, capacitors in pumps, single phase that cause failure to move the pump and going up amp consumer in case of not having the protection system suitable winding pump quite burns, which, in this case at the pump three-phase two categories, coil winding that the power to attach it to.Hurt وحداقل a coil is burned completely and the coil, the other half of the burner or heat, can be seen and a coil corresponding to a definite phase stays intact and in pump single phase winding, the original is burned completely and winding starter stays intact.
- If the pump or motor is working is power, two-phase or wire connection, capacitor in the electric motor, the single phase is interrupted, causing to disassemble هارمونیها and فلوی magnetic contained in the winding and Foucault and هیستر سبزهسته iron stator much is remaining, creating the heat of the iron so a lot can be gotten side going up the amps consumed in category coil, the winding connected to electricity, creating the warmth of copper and wholly winding connected to the power quickly hurt and burns until the fuse act.In this case, the motor is three-phase and one or both of the coil burns and electric motor, the single phase of just winding main burns.A system of protective suits begin with the problem, immediately power off.
Conversely, working pump: In the pump phase, on the contrary, working the pump increases the flow of consumer and not only the pressure and the Dubai Super Low the AMP consumption is also high, and with the thaw, in the case of not having a system of protective suits, winding it burns to fix this problem should be fitting two-phase to each other, swap the spell at the pumps single phase due to a mistake tying wire, starter or capacitor, round, electric motors, etc. The opposite has been the result of pressure on the winding setup is of diameter less and be less is imported, and in case of not having a system, protective fit with climbing amp abusers. winding, bootstrap, instantly burns down. (Note: In this mode, in burning winding three-phase, like the burning time is added, and all the insulation and winding for the same injury sees.)

Training tip

In pumps, single phase, that capacitor bootstrap it out of the pump and by the consumer, etc. can be installed, a general standard is there that most pump manufacturers, it can adhere to them.
Form placement, wire, black, blue, brown, matching the shape of the compliance can be, but if this is the standard compliance is not or no doubt be there with Ohm measured by an ohm meter, accurate, and or digital can wire connection to the capacitor and the power to the procedure below to specify.

Ohms between the common and original (BLK-BLU) always کمتراست of ohms between the subscriber and the starter (BLK-BRN) and being healthy is always ohms between the starter and main (BRN-BLU) field is equal to the sum of the OHM in common with starter + Ohm in common with the original.
The method listed are always for about %98, pump manufacturing is true, except in some cases that mode, the certain wire wrapping, exist of this method for the diagnosis of being healthy or being burned, winding pumps and electric motors that are capacitors, bootstrap it out pack can be used), and in this case, it is better capacitor from the Circuit out, and then the most important decisions in Afghanistan.

Tip one: at the pumps, three-phase, always ohms between connections three phase identical, and a size, which is the box method is also being healthy or not winding specifies.

Tip Two: To test the capacitor, and The طمینان from being healthy, it can leave the rest with connecting the two head capacitor to a cut metal voltage potential capacitors to discharge and then with the Ohm meter that the degree of it, in ohms mode studied. Ohm two سرخازن will we measure in this mode by connecting the two heads of the Ohm meter. Counterclockwise moves and Ohm low start and gradually to Ohm a lot like Mega Ohm arrives with the replacement of two head Ohm meter again, this action can be repeated, if the action repeated, and move counterclockwise from Ohm to Ohm loads, to the extent mega-Ohm, reach, capacitors, healthy, and can be used, otherwise the capacitor corrupted from within the connection are not reliable and should be swapped And be always to select the capacitors, make sure that capacitors are high quality, with micro Rod, determine from the manufacturer and the working voltage above 400V be used.

System protective suits, what is?

Now, considering that any bug in the pump, there will be can make with having a protection system suitable to control it and neutralize us. it should be noted that a system of protective suits, what properties should have.

The same as in the beginning, the booklet was a proper system is the system that in any situation, a burning winding prevent and also a system of protective ideally, multiple-stage control protection is that any who alone can pump to protect this stage includes control amp Consumer, Control phase (to prevent off-load or blue, or extra time), thermal control (which is a TERMO GUARD inside the winding can be controlled)

Controller amp consumption: Must be such that the adjustable for the passage of stream specific, and the size of the set, it is usually due to the amount of the maximum amps determined by the manufacturer to add a maximum of 10%, it is if the controller amp abusers. The type of digital is increasing even 0.2% of the amp more than the size of the designated act immediately and instantly input power cut off, and usually most of these controls digitally equipped to set at least the AMP also is padded to work the pump above or cargo to avoid wasting energy or burning potential control and power input to hang and does not, in any circumstances, the pump will protect (( this is a system perfectly Sure is )), but in the case of thermal controls, such as metal, time needs electricity to the original signal, this type of control, the control accuracy of the digital, not in front of the two-phase any reaction from your do not show this kind of control, and be sure to have a control of the load cell is, but also could as a system Control Act.
Control phase: a system of protection that only pump in front of the two-phase power, or change the phases control no control no other.
Control time: control the load, a protection system that measure the current and voltage consumption rate of load of a pump’s control, this control includes the added burden as well as the low load can be in other words, if the amps consumed more than the limit allowed, or pumps, in effect, empty, working out, etc. amps, less consumption, not sensing it, combined with the original cut and the input power will hang alone for control of the pump is not enough, because there is no control for two-phase AC power supply.

Thermal controls or Termo Guard

This controls the heat inside the winding is installed and from overload thermal formed, usually in a pump single phase, a number, and pumps three-phase three numbers in between the coils of each phase being is usually at the pump that a maximum of one and a half kilowatt of power (1.5 kw) have and amp consumer the maximum 10آمپر will…. can this kind of اورلودها directly in the path of the input power used, but for the higher powers of (1.5 kw) As well as in pumps, three phase with installing them inside the winding and connect it to the interface cable special is used, and to control the temperature, electric motors, etc. it’s in the tableau corresponding to a power outage on the track, reel Contactor uses this type of controller that is usually in all the world, it is customary system is reliable and if suitable to be installed for any reason that the amp Consumable wire بالارفته or heating wire, high Be contact within it, in effect, the heat or the amp more than the size of the opened ومدار main cut it. wire wrapping, such pumps, in Figure below. And the only disadvantages is the lack of the ability to fast in front of the mute, short-circuit or shock is severe and the controller for delay action, and apart from the SHO K and short, with proper closure, the burning of the pump to prevent.

Conclusion

To choose a system of protective full., the first choice of a protection system, digital signage suitable for pump or motor is yours, and otherwise of a switchgear electrical system with relay or contactor K Plus Metal adjustable, for pump, single phase, your choose, and to control the pumps, three-phase from a panel electric system with relay or کنتتاکتور right along with bi-metal fit and adjustable by controlling the phase of the right and control of time of perfect quality, chassis, stop and start to use.

Important note

If the pump or electrical device you burned to repair, the general need to be able indicates that the protection system has not been chosen appropriately. The choice of a protection system suitable pump, the number of years year insurance does and the cost of its initial offset the damage probability of a child. And the cost of its initial compensation for damages incurred the possibility to track and always safely and confidently from the pump or the electric motor of your use, you’ll.

Find out the reasons burning capacity of the Vanities winding

To diagnose the cause of the burning pump. after the control mode of mechanical, such as hit and break part of the pump or burn out, too, corrosion and decay, Body Pump, etc. reasons, the following can be up to 90% in the diagnosis of the causes of burning to help you.

Items that are in pumps, single phase happens

Winding main burned: not having protection system for problems such as time, too, that because it drag fluid viscous or use the pump at the height of unauthorized) which is causing a burning winding becomes the main. The use of the pump درارتفاع less than the designated and authorized by the manufacturer Ledger has been triggered by climbing amp Consumer pump and in case of not having the protection system, etc. the pump is heated and winding its original burns.
Winding starter burned: true, depending not wire the starter and the main winding to the capacitor, the way this نداز relevant, or when you turn on the pump impeller is locked in both mode, if one system protective suits stood there with climbing amp consumer the beginning, winding, bootstrap, burned, and then the main also burns.
Winding starter and main quite burned: pump super dry and on the effect of warming and not having the system after a while, Burns, or connect the pump, single phase to three-phase electric power which, in the absence of a system of protective suits, such as overload or protection, proper flow, etc. the pump above immediately and completely burns. In this mode, if any, control systems, digital signage with climbing even the AMP is too low, the AMP is authorized and also the sensitivity of this type of کنترلرها this type of controller, from the burning of the pump to avoid.
Other items: in case of burning the pump on the effect of water penetration or imperfections related to the winding is incorrect, etc., if any, control systems, etc. in the first connection small, such as body connection or connect two coil or winding, etc. instantly the pump from the Circuit out and never winding to the full face does not burn, and only the effects of spark specifies what action not perfect is that the electric motor or the pump does not work properly.

Items that are in both electric motors and capacity three-phase happens

Winding related to a phase scorched be.: Cut with a phase while working with electric motors and capacity in the event of not having the system phase appropriate to disassemble هارمونیها and فلوی magnetic contained in the winding and Foucault and هیستر سبر iron core stator too much and cause the heat of the iron so much, and causing the heat of the iron so much, and be on the other side, with climbing amp Consumer and create warmth of copper in two categories, rewinding, etc. Super high heat has gone into both categories, Hank damage with burning the first batch coil fuse Safety Act and acts, and does not handle the second coil burns but anyway, a coil that is related to the phase is interrupted stays intact.
Winding two-phase, is burned completely.: Due to not having the system protective suits hang a phase when the starter and turn the electric motor, or capacity, four, Hank got on together مریوط to two-phase connected to the burns, but the phase is disconnected healthy.
Each three-phase, is burned completely.
- The effect of fluid transfer inappropriate and thick or used, in the height of the unauthorized, which makes going up the amp consumer can be.
- Caught a butterfly on the effect of foreign object that caused the top go over the size of the amp consumer can be.
- Empty work out the pump without the water being, that the warming effect, the pump and wasting energy consumed for temperature, cause a gradual winding, and after a while, about 5 to 15 minutes burns.
- To control and prevent the burning, this should pump the super-equipped with protective sensitive to amp consumer or overload thermal can be installed in the path of the relay or coil contactor, be original.
In winding spark fierce seen.: Part of the winding burned and melted the coupling portion of the bobbin winding of view is the mode that in the elongation of the cable and connect Shorten, there comes, in the absence of system protection and short time because the current through the three-phase mode, short-circuit ultra-high-injuries a lot, there comes equipped with a protection system suitable from injuries likely prevent it.
In the winding water droplets can be seen.: There are water droplets on the inside of the winding due to the conductor being, etc. causes shorting wire coil with respect to time, or in proportion to the body, and in case of a system of protection, convenient operation, spark body connection, or the connection between the two کلافت درابتداء move marked wire and a protective or added amp Consumer immediately the power of super cut and makes the hurt much to pump, prevent and otherwise the pump is burned completely and no address of these conditions does not remain.
Special cases: if you see winding on the pump, three-phase or single phase it is determined that all of the insulation, winding, water and all the yarn سربندی wires are torn, and the color of wires, Lacey, little black color is the main cause of load it added that the winding entered, or the system cooling there is not proper. In other words, or whether the pump viscous materials more pumping, or by foreign bodies present in the water, a lot of pressure to the distribution type to be entered or that the pump above the minimum allowed height, the lower is used, or that special pump in submersible or buoys out of the water and acts.

Note: tip

The penetration of water pumps, submersible and floating, apart from the blow to the body in the burnout wire mechanical in operation for quite some time too much or transmission fluid speaking of ruining a flood can be, or the elongation of the cable from the location of the sealing divided into two categories are:

Pump made for high pressure: the peculiarities of the pump made for high pressure that the industry application of loads, and, because the escape of water in the metal, this type of pumps is low with a high going, the pressure strength greater use and prevent the outflow of water pressure has gone up and the AMP consumption goes up, up, where the pressure over the pressure of Hungarians and capacity burns to prevent burning when the design and installation, be sure a route back additional pressure must be to prevent injury embedded to be. In the construction of this type of pumps from the design of diffusers for and butterfly for to add stream thrusters are used, and always in them, and observe the pressure, authorized, recommended, and that it blocked the path of the output water to these pumps serious injuries will be imported.
Pumps made for Dubai high: the peculiarities of pumps made to discharge to the event is added the amount of transfer, discharge, etc. amps consumption has gone up, and is usually public purposes, and Agricultural, are, and always in the consumption of these pumps, the minimum height allowed recommended to prevent the discharge over-sized with the installation of a gate valve help fall to the amount of discharge in unison with consumer, to be pumped and blocked the way, the output of these pumps, they hurt serious not arrive.
