Chemical pump failure analysis and solution

China's current chemical pumps used in the country is a joint design of energy-saving pump, its performance and technology to meet the basic needs and requirements of the market. However, in practical work, the chemical pump can not be as smooth as any other equipment. Next, we will analyze and explain the faults and fault solutions that may be encountered in the chemical pump work. Chemical pump failure analysis and solutions 1, the pump is not absorbent, pressure gauge pointer violent swing Fault Analysis: Insufficient filling irrigation, pipe connections and instrumentation leaks. The solution: check whether the leakage valve at the end of filling, filling the water diversion, tighten or repair leakage. 2, the pump does not water, the vacuum gauge indicates a high degree of vacuum Failure Analysis: The end of the valve is not open or blocked, suction pipe resistance is too high, the suction height is too high. The solution: check the bottom valve, replace the water pipe, reduce the water absorption height. 3, pressure gauge pressure, but still not water Failure Analysis: Outlet resistance is too large, the rotation direction is not correct, the impeller is blocked, the pump speed is insufficient. Solution: check or shorten the water pipe. Check the motor to remove dirt in the impeller to increase pump speed. 4, the flow rate is lower than the design requirements Failure Analysis: Pump blocked, seal ring wear too much, speed is insufficient. Solution: clean the pump and piping, replace the seal ring, increase the pump speed. 5, the pump consumes too much power Failure Analysis: packing gland is too tight, and fever, impeller wear, pump flow increases. Solution: Adjust packing gland tightness, check the pump shaft is bent, replace the impeller, increase water resistance, reduce flow. Through the chemical pump failure analysis and solutions introduced, we should be able to further chemical pumps awareness. In our work and study, many things can not be easy, we will continue to find problems, but also need to continue to sum up experience, and finally to be more perfect. For the chemical pump is the same reason, I believe in the future its development will be even more beautiful.
