Description

Filter pipe, pressure detection mechanism and detection equipment Technical Field The utility model relates to the technical field of pressure detection, in particular to a filter pipe, a pressure detection mechanism and detection equipment. Background In hydraulic systems, pressure detection devices are usually installed at the outlet of a hydraulic pump or at the oil inlet of an actuator, etc., for monitoring the pressure of hydraulic oil. In order to prevent impurities in the hydraulic oil from entering the pressure detection device and affecting the accuracy and normal operation of the pressure detection device, a filter element is often installed in front of the pressure detection device for filtering. The existing pressure detection equipment is generally provided with a filter screen or a filter element inside a liquid inlet pipe, and aims to intercept dust, particles, greasy dirt and other impurities in gas or liquid and prevent the dust, particles, greasy dirt and other impurities from directly entering the detection equipment so as to ensure the detection accuracy and the equipment reliability. However, such designs expose a number of challenges in practical applications: First, the replacement of the filter screen or cartridge is extremely inconvenient. Most filter screens or filter cores are fixed in the device in a bolt mode and the like, when the filter screens or filter cores need to be replaced, operators need to disassemble the liquid inlet pipe layer by layer, and the filter cores or filter screens can be scratched out of the liquid inlet pipe. This process is not only cumbersome and time consuming, but also places high demands on the skill level and patience of the operator, which may lead to damage to the inlet tube or filter cartridge with little carelessness, requiring replacement of the fittings. Secondly, the cleaning and maintenance of the liquid inlet pipe are difficult. In order to ensure the accuracy and performance of the detection device, after the filter cartridge or filter screen is replaced, the area where the filter screen or filter cartridge is placed needs to be rinsed to remove residual impurities and contaminants. However, the inlet tube is often tightly secured for maintaining a seal and is difficult to disassemble individually, which means that the operator must remove the entire inlet tube to perform an effective cleaning operation. The design not only increases the complexity and the workload of maintenance, but also can cause the problem of reduced sealing performance of the liquid inlet pipe in the frequent disassembly and assembly process, thereby affecting the stability and the reliability of the whole detection system. Therefore, the application aims to solve the obvious defects of the existing pressure detection equipment in the aspects of filter screen or filter element replacement and liquid inlet pipe cleaning and maintenance, and seriously influences the use convenience and maintenance efficiency of the equipment.
