Clogging prevention control method of floating water pump

Abstract

The invention belongs to the technical field of water pumps, and particularly relates to a clogging prevention control method of a floating water pump. The clogging prevention control method of the floating water pump includes the following steps that 1, the power of a drive motor of a pump body is monitored; 2, the monitored power of the drive motor is compared with preset power and maximum application power of the drive motor; 3, according to comparison results in step 2, the pump body is controlled to make the floating water pump rotate faster, or the pump body stops working, and when the pump body stops working, water in the floating water pump and water in a water pipe are subjected to back flush. During running of the floating water pump, the flow of the floating water pump is reduced, when the power of the floating water pump increases to be within a preset range, the rotation speed of the floating water pump is moderately increased through a control cabinet, and water flow needed by a customer is ensured; when filter screen clogging becomes more serious and the maximum application power of the floating water pump motor is reached, a back flush command is started; a gap withpreset width exists between the periphery of a filter screen and a floating ring, it is convenient to flush junk inside the floating ring and at the inner sides of filtration pores to the external ofthe floating ring, the situation is avoided that the junk deposits at the inner sides of the filtration pores, and the back flush efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of water pumps, and in particular relates to an anti-clogging control method of a floating water pump. Background technique [0002] Due to the particularity of emergency drainage and rescue, such as the suddenness of events, the urgency of rescue, the complexity of the working face, the safety of operations, the randomness of the construction environment, the environmental protection of the work site, the arbitrariness of time, the continuous Long working hours and other characteristics, which also put forward higher and more professional requirements for the corresponding equipment. The pump used to solve the problem of drainage is an ordinary pump, which has a large volume and weight, and needs to be used in conjunction with external lifting equipment or heavy transportation tools. It has high energy consumption, small displacement, slow response to disaster relief, heavy movement, and insufficient displa...

AI Technical Summary

Problems solved by technology

[0003] In the process of emergency drainage and rescue, the water quality is poor, there are many sundries in the water, and the sundries are of different sizes. The phenomenon of clogging the water pump often occurs, which seriously affects the working efficiency of the water pump. In the prior art, when the water pump is used to pump sewage or medium with many impurities , The outer surface of the water pump filter is constantly covered by impurities, resulting in a continuous decrease in the flow rate of the water pump. After running for a period of time, the water pump needs to be lifted up to clean up the impurities before it can work normally. The operation is very troublesome.
