A, fault phenomenon: pump lose A liquid.
B, reason:
(1) inlet line or with air in the pump body;
(2) the import or export of lateral pipe valves close;
(3) use the head higher than the maximum head of pump;
(4) the pump suction pipe leakage;
(5) error of impeller rotation direction;
(6) on the suction height is too high,
(7) the suction pipe passing small or debris jam;
(8) speed.
C, the processing methods:
(1) filled with liquid, eliminate the air;
(2) open valve;
(3) change the pump head high;
(4) put an end to import side leakage;
(5) the correct motor steering;
(6) reduce the pump installation height, increasing inlet pressure;
(7) increase suction pipe diameter, and eliminate the clog;
(8) the motor speed. |
