Stainless steel horizontal pipeline centrifugal pump is energy-saving, environmentally friendly products, the biggest feature is the smooth operation. In addition, the stainless steel horizontal pipe centrifugal pump common failure, but also according to their own methods to solve the problem, so stainless steel horizontal pipe centrifugal pump is also a convenient product.
Common troubleshooting
Fault one: the pump does not water how to do? Here may lead to no water situation and the solution for the situation:
1. Import and export of the valve is not open, out of the blocked or blocked flow channel impeller, and directly check to remove the blockage.
2. Motor running in the wrong direction, the motor phase speed is very slow, this situation adjust the motor direction, tighten the motor wiring.
3. Suction tube leakage does not lead to water, tighten the sealing surface, remove the leak.
4. Pump is not filled with liquid, the pump cavity with air will lead to no water, to fill the liquid and open the exhaust valve, exhaust air.
5. Insufficient water supply, suction is too high, the end of the valve leakage will not water, need to stop inspection, adjustment.
6. Pipe resistance is too large, improper pump selection, this time to reduce the pipeline bend, re-election pump.
Fault 2: inadequate pump flow, causes and solutions:
Common Troubles and Solving Methods of Stainless Steel Horizontal Pipeline Centrifugal Pump
1. The first reason does not check the water, with the solution to the problem, such as found in the pipeline, the pump flow impeller partially blocked, scale Chen plot, just because the valve opening is insufficient, to remove the blockage, re-adjust the valve opening.
2. Voltage is low, to be regulated.
Impeller wear to be replaced.
Fault three: water power is too large causes and solutions:
1. More than the rated flow, the need to close the small export valve.
2. Suction is too high, you can reduce. Pump bearing wear to be replaced.
Fault 4: motor heating causes and solutions for:
Cause motor heating reasons: excessive flow, overload operation, grazing, motor bearing damage, the voltage is insufficient.
The solution is: close the small outlet valve, check to exclude, replace the bearings, voltage regulator.
Fault 5: a noise vibration, the causes and solutions:
Stainless steel horizontal pipe centrifugal pump caused by noise caused by vibration reasons: pipe support instability, liquid mixed with gas, resulting in cavitation, bearing damage, the motor overload heating operation of these five reasons.
The solution is: a solid pipeline to improve the suction pressure exhaust, reduce the vacuum, replace the bearing and the motor cooling method.
Fault 6: water pump leakage, the causes and solutions for:
Water pump leakage reasons: mechanical seal wear, the pump has a sand hole or rupture, sealing surface is not flat, loose bolt installation.
The solution is: replace the dressing seal, welding or replacement of the pump body, fastening bolts can be installed.
