Online health monitoring system for oil filter system and metal folding hydraulic oil filter element

Abstract

The invention relates to the technical field of mechanical hydraulic equipment, and discloses an on-line health monitoring system for an oil filter system and a metal folding hydraulic oil filter element. The on-line health monitoring system for the oil filter system comprises a micro differential pressure sensor, the micro differential pressure sensor comprises a glass tube, and a middle permanent magnet is arranged in the middle of the glass tube; magnetic liquid is adsorbed on the middle permanent magnet, a first hollow magnetic ring and a second hollow magnetic ring are arranged in two end tubes of the glass tube, a first Hall element and a second Hall element are arranged outside the glass tube, and the range of the micro differential pressure sensor is adjusted by axially moving the first Hall element and the second Hall element; signals of the micro differential pressure sensor are output to the upper computer, and the upper computer processes the signals to obtain the pressure of the inlet and the outlet of the filter tank. According to the invention, the online real-time monitoring of the hydraulic oil filter element can be realized, the fault filter element can be alarmed, the accurate maintenance and replacement are facilitated, the measurement range is adjustable, and different production requirements can be met.

Description

technical field [0001] The invention relates to the field of mechanical hydraulic equipment, in particular to an on-line health monitoring system for an oil filter system and a metal folding hydraulic oil filter element. Background technique [0002] In the hydraulic system, the cleanliness of the hydraulic oil has a great influence on the working reliability and service life of the hydraulic components and systems. Hydraulic oil plays the role of transmitting pressure, lubrication, cooling and sealing in the hydraulic system. Clean hydraulic oil is the life of the hydraulic system. There are many precision parts in the hydraulic system, and some have damping holes or gaps. The intrusion will cause strain on precision parts, card issue, blockage of oil passages, etc., which will affect the safe operation of the hydraulic system, greatly increase the failure rate, and seriously affect the reliability and service life of the machine.
