Problems solved by technology

At present, the cleaning method is mainly to use manual devices such as hand pumps to clean hydraulic equipment. This type of device is cumbersome to operate, unable to filter the oil, unable to clean the oil circuit, unable to know the degree of oil pollution, and easily causing secondary pollution. , It is difficult to fill completely and other disadvantages, and at the same time, it is impossible to realize the effective control of the quality of the filling oil
Moreover, this type of device cannot realize the rapid discharge of gas in the oil. After filling, the hydraulic equipment needs to stand still for more than 24 hours before it can be used, so it takes a long time

Abstract

The invention discloses an online oil filling and purifying device for hydraulic equipment. The main design points are that: an oil tank is provided with a vacuumization control system; the oil tank is divided into an absolute oil tank and a dirty oil tank; the absolute oil tank is provided with an oil inlet pipeline; the dirty oil tank is provided with an oil drain valve; an online circulating filtration system comprises a dirty oil pipeline communicated with the dirty oil tank and an absolute oil pipeline communicated with the absolute oil tank; the dirty oil pipeline is provided with a dirty oil electromagnetic control valve; the tips of the dirty oil pipeline and the absolute oil pipeline are respectively provided with a dirty oil pipeline quick connector and an absolute oil pipeline quick connector which are communicated with the oil tank of the hydraulic equipment; the dirty oil pipeline is communicated with the absolute oil pipeline through an isolation electromagnetic valve, aone-way valve and a gear pump; and a pressure filter is arranged in the absolute oil pipeline. The online oil filling and purifying device for the hydraulic equipment designed in the invention has the characteristics of high integration degree, complete functions, compact structure, and high maneuverability and maintainability.

Description

technical field [0001] The invention relates to hydraulic equipment, in particular to a special device for oil filling and cleaning and filtering of hydraulic equipment. Background technique [0002] Hydraulic equipment is widely used in mechanical equipment in various industries, and the cleanliness of its oil and oil circuit is an important condition to ensure the normal operation of the equipment. In order to ensure the cleanliness of the hydraulic system, people usually take the following measures: 1) Regularly replace the hydraulic oil (generally, the hydraulic oil must be replaced in about half a year, and the hydraulic oil must meet the requirements); 2) Before injecting new oil into the oil tank, it must be filtered through precision ; 3) Use a qualified filter element, which must be replaced when an alarm occurs or every three months; 4) Regularly check the oil quality, and change the oil once the oil quality drops. Said method not only has many procedures, but als...
