Description

TECHNICAL FIELD

[0001] The utility model relates to submersible pump field especially involves a submersible pump filter screen protection device convenient to dismount and clean. BACKGROUND

[0002] Submersible pump is the important equipment of deep well water lifting. When using, the whole unit is submerged in water to work, and the underground water is extracted to the ground surface, which is the equipment of life water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship load adjustment, and can also be used for fountain landscape. Hot water submersible pump is used for hot spring bathing, and can also be used for extracting underground water from deep well, and can also be used for river, reservoir, water channel and other water lifting engineering.

These impurities may cause the pump body to be blocked, the wear to be aggravated, the performance to be decreased and even damaged, and also affect the pumping efficiency and service life of the submersible pump. The filter screen can effectively filter out these impurities to ensure that the submersible pump inhales relatively clean water flow, thereby protecting the pump body from damage, improving the working efficiency and stability of the submersible pump, and prolonging its service life. However, after long-term use of the filter screen, impurities, particulate matter and dirt such as silt and leaf fragments in the water will accumulate in the filter screen, which will gradually block the filter screen, affect the water flow smoothness, and cause the pumping efficiency of the submersible pump to decrease, and even the submersible pump may not work normally due to complete blockage of the filter screen. Therefore, the filter screen needs to be dismounted and cleaned regularly. However, in order to ensure that the filter screen is stably installed on the submersible pump and prevent it from moving or falling off during work, the filter screen is generally fixed on the bottom or water inlet of the submersible pump by bolts or other fasteners, so that the filter screen needs to be dismounted by auxiliary tools when cleaning, which is relatively troublesome to operate, thereby bringing inconvenience to the dismounting and cleaning operation of the submersible pump filter screen and affecting the use efficiency of the submersible pump.
