Answer: (1) The elevator is too high, use it according to the lifting range (2) The mesh cover and water inlet hole are blocked, remove aquatic plants and others debris (3) The wheel is seriously worn, replace it. the impeller (4) The diving depth of the electric pump is shallow and there is air. Suction adjusts the diving depth of the electric pump (5) The impeller is reversed to exchange any two phases of the three-phase electric pump. http://www.jhtsb.com/plus/view.php?aid=361
When the pump stops, the water in the pipe flows back. What damage will this cause to the pump?
---------Before installed, the water in the storage tank will flow backwards, and when the water pump works, it will pump the water from the storage tank together. “swimming pool”
As picture shows; In the sentence above, if the pool you mentioned is located under the official end under the ccheck valve and you have not shown it in the picture, the installation position is correct. ,
When the pump stops, the water in the pipe flows backwards. Reversing the feed water pump will also cause the front pump motor to burn out and the pipeline between the front pump and the main pump to leak.
A pump is a machine that transports a liquid or puts a liquid under pressure. It transfers mechanical energy from the prime mover or other external energy to the liquid, thereby increasing the energy of the liquid. The pump is mainly used to transport liquids such as water, oil, acid and alkali liquids, emulsions, suspoemulsions and liquid metals. It can also transport liquids, gas mixtures and liquids containing suspended solids. Pumps can generally be divided into three categories: positive displacement pumps, ldynamic pumps and other types of pumps depending on their operating principles. In addition to classification according to operating principles, they can also be classified and named according to other methods. For example, according to the driving method, it can be divided into electric pumps and water wheel pumps according to the structure, it can be divided into single-stage pumps and multi-stage pumps according to the use, it can be divided ; in boiler feed pumps and metering pumps; according to the properties of the transported liquid, it can be divided into water pumps, oil pumps and mud pumps, etc. According to the structure with or without shaft, it can be divided into linear pumps and traditional pumps.
