The cause of the high temperature super self-priming pump motor current and the solutions

self-priming pump super current reason, the cause of the high temperature self-priming pump motor, self-priming pump than current solution

the occasional users reflect the new buying self-priming pump products why motor temperature is high, the hand can't touch, under normal circumstances the motor temperature should be less than 60 & deg; Only belongs to the normal c, motor maximum allowable temperature cannot exceed 80 degrees Fahrenheit, new self-priming pump motor temperature is very high and it is possible that the user actually use the head caused by the low and high pump lift self-priming pump motor over current caused by the specific cause of self-priming pump motor temperature is very high and self-priming pump super current solution can refer to the following:

1, due to some users to buy self-priming pump products is to entrust a third party to purchase, middle details about self-priming pump selection is no good communication, such as the actual use of head only 5 meters and choosing a self-priming pump opted for a 15 - 20 meters of lift self-priming pump, this kind of situation will appear after to install and use super self-priming pump motor current and the phenomenon of self-priming pump motor temperature is very high, this kind of situation if buy self-priming pump lift and use little head disparity in 5 meters can also by small flow control valve to adjust current, it is very difficult, if disparity is too big to rely on valve control at that time only consider changing small impeller head do little or increase motor power to solve the problem, and you also can choose other do not belong to the theory of centrifugal self-priming pump products such as: gas liquid self-priming pump or pneumatic diaphragm pump driven by gas source

80 head 20 meters below self-priming pump operating conditions:

a pump length 19. 5 meters ( Level 16. 5) High, 3. 2 meters, elbow 4. Another pump length 37 m ( Level 33. 5) High, 3. 2 meters, 10 bend.

control valve opening also can't control current, finally can only choose the self-priming pump vane reprocessed narrow around 8 mm lower his head to be used.

2, because the installation process after the foundation uneven in a fixed foundation bolt self-priming pump motor and pump body balance, coupling manual barring obvious difficulties, lead to motor overload makes it super current caused by temperature is too high, this kind of situation need to adjust the balance to be used.

3, if the voltage instability is also lead to the motor burning, when three-phase voltage asymmetry, namely the phase voltage is high or low will lead to some current is too large, the motor heat, so must reach the required voltage, amounted to less than the rated voltage of motor running easily lead to instability will cause burning serious burn out motor.

4, a circuit breaker or contactor contact undesirable, electrical wiring connected is bad or good contact aging leads to lack of phase caused by the motor overload can lead to burning and burning motor, the power cord a phase power outages caused by other devices on the road, meet in the same line will also lack of phase operation of other equipment.

5, because the user use too much liquid viscosity is bigger, can also lead to motor current overload, encounter this kind of situation need to medium density and viscosity increase the motor power in order to solve the problem, high viscosity suggested use: high viscosity self-priming pump
