Problems solved by technology
[0002] The existing self-cleaning filter uses the cylinder to drive the rotary valve to clean the filter element. There are only two filter chambers, one chamber is working, and the other chamber is standby. For the use under the conditions of high flow and high precision, the outlet pressure of the filter will drop. The filter is frequently backwashed, and the flushing is not clean, and the maintenance time is short
[0003] At the same time, the existing filter needs to be disassembled and inspected in the case of slide valve failure. First disassemble the rotary valve, and then take out the slide valve. It is impossible to directly disassemble and maintain the faulty parts. The cumbersome disassembly and installation process greatly increases maintenance costs.

The invention discloses a novel large-flow high-precision fuel oil self-cleaning filter, which comprises a shell, a filter element, a rotary valve and a filter chamber with an exhaust device, whereinan inlet flange for a filtering medium to flow in is arranged below the shell, an outlet flange for the filtering medium to flow out is arranged above the shell, the upper part of the shell is provided with a cam, a travel switch and a gear motor, the lower part of the shell is provided with a blow-down valve shell and a heating cavity, an air storage chamber is arranged at the side edge of the shell, and a differential pressure transmitter is arranged at an inlet and an outlet of the filter for measuring differential pressure of the inlet and the outlet. According to the invention, the requirements of working conditions with large fuel flow and high filtering precision can be met; and the filter is stable in outlet pressure during backwashing, reasonable in structure, convenient to mountand dismount, economical to maintain and safe and reliable to use.
Description
Technical field [0001] The invention relates to the technical field of self-cleaning filters, in particular to a new type of high-flow high-precision fuel self-cleaning filter. Background technique [0002] The existing self-cleaning filter uses a cylinder to drive a rotary valve to clean the filter element. There are only two filter chambers, one for working and the other for standby. For use under high-flow and high-precision working conditions, the outlet pressure of the filter will drop. The filter is frequently backwashed, and the washing is not clean, and the maintenance time is short. [0003] At the same time, the existing filter needs to be disassembled and inspected as a whole when the spool valve fails. The rotary valve is disassembled first, and then the spool valve is taken out. The failed parts cannot be disassembled and maintained directly. The cumbersome disassembly and installation process greatly increases maintenance costs. Summary of the invention [0004] The p...
