Centrifugal pump water or difficult to start troubleshooting is as follows:
ã€cause of issue】
(1) water pump irrigation dissatisfaction with water;
(2) pump irrigation can not enter the water;
(3) the valve leakage at the end of the valve closed;
(4) bottom valve stuck by debris;
(5) pump or suction pipe leak, vacuum pump pumping can not be a vacuum;
(6) vacuum system failure;
(7) vacuum pump insufficient supply of water or lack of suction capacity of the vacuum pump;
Exclusion
(1) Check the end of the valve and the suction pipe is leaking, the bottom of the pump emptying screw or valve is closed;
(2) Pump casing top or vent valve is open;
(3) a large number of irrigation, forcing the end of the valve closed, if not the end of the valve may have been bad. Must try to overhaul;
(4) Check the valve and try to remove debris;
(5) Check the suction pipe and connecting flange itself is leaking, tighten the packing gland.
