AI Technical Summary
Technical Problem
In existing technologies, filter replacement time is set based on experience, which cannot accurately determine the degree of clogging, leading to resource waste or the risk of hydraulic system shutdown.
Method used
Design a filter with a differential pressure transmitter. The filter cartridge is detected by a differential pressure sensor and a magnet system, which issues an alarm and automatically bypasses the filter when necessary to prevent system shutdown.
Benefits of technology
This allows for timely replacement of filter elements when they become clogged, avoiding resource waste, ensuring the normal operation of the hydraulic system, and preventing system downtime.

Abstract
The utility model belongs to the pipeline filter field technical field, concretely relates to a filter with pressure difference transmitter. The utility model discloses the oil inlet pipe and oil outlet pipe, and the one end of oil inlet pipe is connected with the one end of oil outlet pipe through filter bowl, and the lateral wall of oil inlet pipe and the lateral wall of oil outlet pipe are linked through bypass pipe, the lateral wall of oil outlet pipe is fixed with bypass valve, the bypass valve is equipped with plug driving element and movable plug, the plug driving element drives movable plug to block up or open the hole of bypass pipe through the pressure size in bypass pipe, the differential pressure transmitter is installed between oil inlet pipe and oil outlet pipe, and the differential pressure transmitter is used to show warning when the filter bowl inside is blocked. When the filter bowl is blocked, the utility model can show warning to the staff through the differential pressure transmitter to remind the staff to replace the filter core in the filter bowl in time, and also can make oil inlet pipe and oil outlet pipe communicate through bypass valve to prevent the whole hydraulic system from stopping because of the filter bowl inside is blocked.
