Problems solved by technology

Most of the existing hydraulic accessories are for a single function, such as system hydraulic oil filtration and flow measurement, which require different hydraulic accessories to work together, which not only makes the system complicated and cumbersome, but also increases the cost to a certain extent. At the same time, the traditional flowmeter has installation The conditions are relatively harsh (the front and rear straight pipe sections are required to be too long), and the maintenance is complicated, etc.

Abstract

A hydraulic system return oil filter device with a flow measuring function is characterized in that a cylindrical filter screen is arranged in a main casing with an oil inlet at the lower end, and an alarm and a temperature measuring device can be arranged at an upper end cover above the filter screen. A throttling ring is arranged at the end top of a horizontal portion of the main casing, a movable casing is arranged outside the throttling ring, two vertical through holes are formed in each of the main casing on two sides of the throttling ring and the lower wall of the movable casing and correspond to vertical through holes on the upper wall of a differential pressure transmitter arranged below, a cover plate is arranged on a casing opening of the differential pressure transmitter and is provided with a signal transmission port on the outer side, two sensors connected with the signal transmission port are arranged in communicated through holes of the main casing and an auxiliary casing respectively, the inner side of the cover plate is connected with one end of a spring, and the other end of the spring is connected with a piston arranged between the two vertical through holes. The hydraulic system return oil filter device integrates functions of filtering and flow measuring of hydraulic oil and has the advantages of compact structure, accuracy in measuring, low cost and convenience in maintenance.

Description

technical field [0001] The invention relates to an accessory of a hydraulic system, in particular to a filter device for oil return of the hydraulic system. Background technique [0002] The main function of the filter of the hydraulic system is to filter the solid pollutants in the working medium of the hydraulic system to maintain the cleanliness of the working medium. Most of the failures of the hydraulic system are caused by the pollution of the working medium, so the filter is indispensable for the hydraulic system. Lack of. Flow is also a very important technical parameter in industrial production detection and control. Most of the existing hydraulic accessories are for a single function, such as system hydraulic oil filtration and flow measurement, which require different hydraulic accessories to work together, which not only makes the system complicated and cumbersome, but also increases the cost to a certain extent. At the same time, the traditional flowmeter has i...
