Small stainless steel submersible pump is printed in accordance with a certain standard design. Therefore, the use of electric pumps must meet the standard conditions of use, in order to ensure the reliable operation of pump and service life. Failure to comply may result in premature failure of the pump and affect the user's production and operation.
Small stainless steel submersible pump use conditions are:
(1) the water temperature not to miss 20 degrees;
(2) the solid content of water by weight, for ordinary small stainless steel submersible pump does not exceed 0.01%, for a special small stainless steel submersible pump is not more than 0.05%;
(3) water was neutral, ph value in the o. 5-8.5;
(4) the content of chlorine ions and sulfur ions in the water are not more than 400 mg per liter.
Small stainless steel submersible pump before use, shall use a megger to check the motor insulation resistance, the minimum value can not be less than 50MΩ.
Flooding motor should be open irrigation plug, filled with clean water and then tighten the plug, can not be screwed into the irrigation plug screw directly into the well.
Check the cable for breakage before use. If damage should be replaced in time to prevent leakage. Small stainless steel submersible pump should be injected into the pump before the water, and then idle for 1-2 minutes and start twice to check whether the normal start and idle, turn to meet the requirements. If the steering is reversed, replace any two-phase wiring.
Install a small stainless steel submersible pump, the cable to overhead, the power cord should not be too long. Do not force the unit into the water, so as not to cause the power cord breakage. Small stainless steel submersible pumps do not sink into the mud, otherwise it will lead to poor heat and burn the motor windings. Try to avoid low-voltage boot. If the voltage is too high, it will cause the motor to overheat and burn out the winding. If the voltage is too low, the motor speed will decrease. If it does not reach 70% of the rated speed, the centrifugal switch will be closed and the starting winding will be closed. Long-term power and heat or even burn out the winding and capacitors. Do not frequently switch the motor, this is because the small stainless steel submersible pump will stop when the return flow, if the immediate start, the motor load will start, resulting in starting current is too large and burn out the winding.
Production process only gives the normal flow should be considered to leave some margin For ns <100 large flow low unexpected pump flow margin to take 5% on the ns <50 small flow high lift pump flow allowance take 10% 50 ≤ ns ≤ 100 pump flow margin also take 5% of poor quality and poor operating conditions of the pump flow margin should be taken 10%.
