A hot water circulation pump failure water causes 1. Hot water pump inlet and outlet valves are not open, out of the pipeline obstruction, abortion impeller blockage. Solution, remove obstruction.
2. Motor running in the wrong direction, motor phase loss is very slow. Adjust the motor direction, sturdy motor wiring.
3. Hot water circulation pump suction pipe leaks. Tighten the sealing surface, remove the air 4 pump is not filled with liquid, the pump cavity with air. Open the pump cover or open the exhaust valve and drain the air.
5. Inadequate supply of import and export, suction stroke is too high, the valve leaks. Shutdown inspection, adjustment (water pipe and pipelines with suction easy to use this phenomenon).
6. Pipeline resistance is too large, improper selection of centrifugal pumps. Reduce the pipeline bend, re-election pump II. Hot water pump failure flow reasons 1. Hot water circulation pump import and export valves are not open, out of the pipeline obstruction, abortion impeller blockage. Solution, remove obstruction.
2. Pipeline, hot water circulation pump impeller impeller blockage, scale deposition, valve opening insufficient. Remove the obstruction and readjust the valve opening.
Centrifugal pump voltage is low. Regulated.
Impeller wear. Replace the impeller.
5 over the rated flow use. Regulate the flow off small outlet valve.
Centrifugal pump suction is too high. Lower suction.
7. Pump bearing wear. Replace the bearing.
Three hot water circulation pump malfunction noise vibration reasons 1. Pipe support instability. Stabilize the pipeline.
Liquid mixed with gas. Increase suction pressure exhaust.
3. Cavitation generated. Reduce the degree of vacuum
4 bearing damage. Replace the bearing.
5. Motor overload heating operation. Regulate the flow off small outlet valve.
Four hot water circulation pump fault motor heating reasons 1. Hot water circulation pump flow is too large, overload operation. Close the small outlet valve 2. Rub. Check exclusion.
3. Hot water circulation pump motor bearing damage. Replace the bearing.
Insufficient voltage. Regulated.
Five hot water circulation pump failure reasons 1. Hot water circulation pump mechanical seal wear. replace.
2. The pump has sand holes or cracks. Welding repair or replacement.
3. sealing surface is not flat. Trimming.
4. Loose mounting bolts. Tighten.

Hot water circulation pump is a centrifugal pump model of a product. Thermal circulation pump temperature within 120 degrees, the installation is divided into vertical and horizontal 2 kinds. Hot water circulation pump failure is not the main water, lack of flow, noise, vibration, leak several kinds of failures below to explain the various causes of failure and solutions.
