WFB non-sealed self-priming pump and its handling of common failures

WFB seal-free self-priming pump failure and the corresponding solutions are the following: WFB seal-free self-priming pump failure and treatment methods common First, the connection pipe and pump leaks , The pump can not form a vacuum, non-suction caused by the failure of the reasons there are usually two: 1, is the gasket aging, lax closed labyrinth. 2, is the control valve and pump connections leak. The solution to this problem is to first check and handle the connections and then replace the gasket. Second, the motor and pump connection site leaks in the start moment, but does not leak during normal operation: The cause of the failure is the working pressure exceeds the pump parameters, then resolutely the method of failure can only reduce the work pressure. In addition, you can assist in opening the outlet valve before starting, shut down slowly after normal operation. Third, the connection parts of the motor and pump leakage at work, the failure Usually pay the impeller and the pump cover gap is too large, the solution just adjust the gap size of 0.5-1MM. Fourth, the flow, lift (pressure is not compliance) The cause of the failure is more diverse, may be the following conditions: 1, the container or liquid tank too little, sometimes sucked into the air; 2, the motor reversal; 3, Liquid absorption end of a only cut blue, the valve or pipe somewhere chronic leakage, affecting the pump vacuum; 4, the bottom of the filter block, over-current lack of 5, the voltage is too low, the rated speed of less than solution is to check one by one , For exclusion. Fifth, the electric air control valve part, the piston is not sealed or closed lax, pump non-suction: The failure is usually only two reasons: 1, poor contact with the motor terminal or fuse damage, the power barrier, seal piston does not move. The solution to this problem is to check and connect the power supply; 2, the guide shaft lost oil stuck, sealed piston is not in place, the solution is to add oil lubrication; Sixth, the pump does not water failure causes may have the following four, one by one investigation can. 1, no liquid in the container or liquid pool 2, a liquid suction port only cut a large number of valves, valves or pipe leaks 3, drain or vent mouth no gaskets within the cap 4, the drainage of less than seven, the motor does not turn into The failure of the following conditions: 1, the power barrier, the solution is naturally check the power 2, the motor is damaged, the solution is to replace or repair the motor WFB seal-free self-priming pump, we just keep in mind Seven major problems and solutions, I believe it will be able to solve ninety-nine percent of the failures, so that the product to better serve you.
