Water pump with blowdown discharge outlet

Abstract

The invention relates to the technical field of pump valves, in particular to a water pump with a blowdown discharge outlet. The technical scheme includes that the water pump comprises a pump body, an impeller, a shaft, a water inlet and a water outlet, the impeller and the shaft are mounted in a body of the water pump, the water inlet and the water outlet are mounted on the body of the water pump, the blowdown discharge outlet is mounted at the water inlet, a filter screen is arranged in the blowdown discharge outlet, a sealing cover is arranged on the blowdown discharge outlet, and a sealing pad is arranged on the sealing cover. The water pump with the blowdown discharge outlet has the advantages that by arranging the blowdown discharge outlet at the water inlet and mounting the filter screen in the blowdown discharge outlet, delivered substances can be cleaned certainly when the water pump delivers water and oil, and impurities can be prevented from entering the water pump, so that after use of the water pump, the impurities in the water pump can be removed by opening the blowdown discharge outlet and taking out the filter screen, the water pump is prevented from being detached to clean the impurities, and labor and time are saved.

Description

technical field [0001] The invention relates to the technical field of pump valves, in particular to a water pump with a cleaning port. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid, and is mainly used to transport liquid, oil, etc. During the use of the water pump, the water or oil conveyed sometimes contains some impurities. These impurities are transported to the water pump together with the water or oil. When the impurities accumulate to a certain extent, it will affect the operation of the water pump and even damage the pump. water pump.

Problems solved by technology

During the use of the water pump, the water or oil conveyed sometimes contains some impurities. These impurities are transported to the water pump together with the water or oil. When the impurities accumulate to a certain extent, it will affect the operation of the water pump and even damage the pump. water pump

Existing water pumps often do not have a cleaning port, so when transporting special water and oil containing many impurities, it is often necessary to disassemble the connection port between the water pump and the water pipe after a period of time, or even disassemble the entire water pump to clean the water pump. Cleaning, this will not only affect the work of the water pump, but also need to waste a lot of manpower and time to clean the water pump
