1hp Marathon motor running on 110V 126A. Once the pump is up to speed you open the discharge valve and as flow rises so does amp draw.

Pump Overloading And Its Causes Enggcyclopedia

The windings ohm at.

. Stator is 9 wire. This is why we start large centrifugal pumps with the discharge shut or mostly shut to minimize starting current. Go to a 20 amp breaker box.

Thank you all really. Pump was brought to us not working. We are talking about the efficiency of the impeller.

Pump was brought to us not working. Should be drawing 7 amps per leg per mfg specs. Motor will run for a while thermo will pop from overheating cool and then restart.

One of the other technicians condemned the compressor but other than the high amp draw the compressor would not indicate any problems. Feb 1 2009 0833 AM. A GM central point injection CPI pump 55.

Now unit is drawing 30 amps per phase. A pump with a bad bearing from 2007 means you might be pumping the well dry from time to time. The voltage at the disconnect is 235V and there is a drop of 10V when starting the compressor.

Water pump motor drawing high amps at start up. Megged the stator and it checked out good. Measure amp draw on each leg 4.

Remegged stator again and it is good. 460V 3 phase submersible pump. In short motor under load is drawing 18-20A.

Liberty Pumps Landing. I know that the motor will draw high amps at start up but the high amps stays high for about 8 to 10 seconds. The pump and motor are in a pit with an air bladder.

Replaced seals and bearings. Remegged stator again and it is good. When flow increases pressure decreases.

A 150 load will trip after say 2 minutes. Lack of airflow through the condenser causes the condenser fan motor to run hotter than normal and the compressor to run hotter because of the higher load conditions. One good fuse now costs as much as a breaker usually more.

As long as a motors torque ie rotational force doesnt change a motors speed will have a one-to-one relationship with voltage. Answer 1 of 3. Since both your flow rate and your discharge pressure are less than design the.

Should be drawing 7 amps per leg per mfg specs. The compressor is not shorted to ground and has no open windings. Results in higher pressures in the condenser which causes the compressor to pull amps.

Im about to rewire my pool pump to 240v and just for SG I threw an amp meter on the hotwire within my breaker panel and it said the motor was. Higher amp draw means higher electric bills. A test of the pump wiring itself for deteriorated or damaged insulation low resistance breaks infinite resistance and dead shorts to ground zero or close to zero resistance 2.

This could be caused by very hig. The design duty was 19 ls 70 kpa. I have a 240 volt motor for our water pump that draws high amps for a long period when it turns on.

The actual site measuremnts are 151 ls 65 kpa and drawing 19 amps. No known voltage drops. Watts have a direct relationship with volts which can be expressed by the following mathematical formula.

High Amps on newly replaced pump high Amps on newly replaced pump somacast Mechanical OP 23 Jan 17 0635. High Amps on newly replaced pump. Stator is 9 wire.

ScottyUK Electrical 25 Jan 17 0643. Count wash pump nozzles. Answer 1 of 8.

Pumps are not so simple but within the operating range of a centrifugal pump amps increase as flow increases and amps decrease as pressure decreases. Hayward Super II Pump. 460V 3 phase submersible pump.

All of this information is described on the pump curve. If the voltage falls the motors speed will decrease by the same amount. But as you said its low HP pumps but special type canned motor old pump used to draw about 52 Amps when operated too 205 C.

Now unit is drawing 30 amps per phase. The lower the well level the less water is forced into the impeller of the pump the less water is moved which means lower amp draw providing the head stays the same. Megged the stator and it checked out good.

The starting current of motors is generally high. We are a submersible pump rebuild shop. Joined Apr 20 2004.

The percent of increase in flow should be cubed and the percent of decrease in pressure. If the voltage is low then it will draw extra current to compensate power is volts times amps. For a centrifugal pump Amps is directly related to work performed which is related to flow rate.

This sounds to me as if the motor is overheating or is damaged and is drawing high current amps. The bad one could not get past the low speed region 436 rpm showing 869086 amps which would delay the motor. This is typically but not exclusively caused by excess mechanical load.

Secondary motor windings were rated at 1040 volts 275 amps. There are at least two common electrical tests. If flow goes down amps will go down.

Power draw is a function of flow rate and head. High-pressure pumps like those in port fuel injection PFI systems 35 to 45 psi require more current than low-pressure pumps in throttle body injection TBI applications 9 to 13 psi. Measure incoming voltage with pumps off and with pumps running 3.

Replaced seals and bearings. Read and report motor nameplate data HP FLA and SFA Total Number of nozzles Voltage Static machine off Leg 1 Leg 2 Leg 3 Voltage Running all pumps running Leg 1 Leg 2 Leg 3. A TBI pump may have a normal current draw as low as 3 to 5 amps with PFI pumps pulling 4 to 6 amps on average.

A good pump 6 operated fine at full speed producing rated flow and pressure with the amps at three phases showing good current balance of 838383 amps. The device that protects a pump motor usually has a time inverse characteristic. Watts Voltage Amps.

A 110 load will trip after say 30 minutes. 15 amp fuse is pretty small for a 15 hp motor especially with the quality of the fuses I have sometimes found. Click to see full answer.
