Anti-deformation detachable filter screen for water feeding pump and mounting method of anti-deformation detachable filter screen

Abstract

The invention discloses an anti-deformation detachable filter screen for a water feeding pump and a mounting method thereof, relates to the technical field of filter screens of water feeding pumps, and aims to solve the problems that an existing filter screen of a water feeding pump is single in structure, poor in anti-deformation capacity, prone to deformation when water pressure is large, and low in working efficiency due to the fact that manual disassembly and cleaning are needed after the filter screen is used for a certain time. The second cover shell is arranged below the first cover shell, connecting pieces are installed on the two sides of the first cover shell and the two sides of the second cover shell correspondingly, the adjacent connecting pieces are in threaded connection through a plurality of bolts, internal thread walls are arranged on the inner walls of the two ends of the first cover shell and the two ends of the second cover shell correspondingly, and a sealing connector is installed on the upper surface of the first cover shell. The number of the sealing connectors is two, a dual-purpose nozzle is installed at one end of each sealing connector, and one end of each dual-purpose nozzle penetrates through and extends into the first housing.

Description

technical field [0001] The invention relates to the technical field of feedwater pump filter screens, in particular to a deformation-resistant detachable filter screen for feedwater pumps and an installation method thereof. Background technique [0002] The feed water pump inlet filter is also called the condensate pump inlet filter, which is used at the inlet of the condensate pump of the condensate tower of the thermal power steam boiler to eliminate impurities in the medium to protect the normal use of equipment and valves. When the fluid enters the filter cartridge with a certain size filter, the impurities are blocked, and the clean filtrate is discharged from the filter outlet. When cleaning is required, just take out the detachable filter cartridge and reinstall it after treatment. [0003] However, the existing feed water pump filter has a single structure and poor deformation resistance. If the water pressure is high, it is easy to deform, and after a certain period...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a detachable anti-deformation filter screen for feed water pump and its installation method, so as to solve the problem that the existing feed water pump filter screen proposed in the above-mentioned background technology has a single structure and poor deformation resistance. When the pressure is high, it is easy to deform, and after a certain period of use, it needs to be manually disassembled and cleaned, and the work efficiency is low.
