Technical Field

The invention relates to the field of pumps, in particular to a novel automatic filter screen backwashing device.

Background

The deep well submersible pump has the advantages of simple structure, high unit efficiency, low noise, safe and reliable operation and convenient installation and maintenance. It is suitable for extracting water from deep wells, hot wells and oceans, and can also be used for extracting rivers, reservoirs, canals and the like: the utility model discloses a water supply and drainage system, including filter, filter screen, the filter screen is including the water inlet end, the filter screen is including the filter, the.

However, the filtering part of the existing backwashing device needs to be detached and cleaned, which is laborious, and a plurality of electric valves are adopted on a single water pump, so that the circuit for controlling the opening or closing of the valves is complex.

Disclosure of Invention

The invention aims to provide a novel automatic filter screen backwashing device to solve the technical problems.
