Problems solved by technology

[0003] In order to solve the problems of the existing four-roller crushers such as poor protection effect of iron passing, short hydraulic system holding time, serious oil leakage, etc., the present invention proposes a hydraulic control system for four-roller crushers. The pressure holding time is short, and the production automation is realized; the hydraulic cylinder has a rod cavity that automatically absorbs oil during the iron-over protection, which improves the automatic iron-over protection function of the equipment; the hose shock isolation completely solves the serious problem of oil leakage on site

Abstract

The invention discloses a four-roller breaker hydraulic control system which comprises an oil tank (1), a filter (2), a gear pump (3), a motor (4), a pressure gauge (5), a two-position two-way magnetic exchange valve (6), a system overflow valve (7), a one-way valve (8), a three-position four-way magnetic exchange valve (9), a hydraulic control one-way valve (10), a pressure relay (11), an energy accumulator (12), a safety valve (13), a one-way throttling valve (14) and a synchronous hydraulic cylinder (15). Due to structural transformation, the problem that the dwell time of the system is short is solved, and in addition, production automation is achieved; during iron passing protection, a rod cavity of the hydraulic cylinder automatically sucks oil to improve the automatic iron passing protection function of equipment, and a hose insulates shock so that the problem of severe field oil leakage is thoroughly solved.

Description

Technical field [0001] The invention relates to the field of crushers, in particular to a hydraulic control system for a four-roll crusher. Background technique [0002] The roll gap adjustment devices of the existing four-roll crusher are all hydraulic. Theoretically speaking, the outstanding advantages of this device are convenient roll gap adjustment, labor-saving, low machine noise, and easy implementation of iron-over protection. However, many problems are exposed during actual use, such as roll gap adjustment and maintenance. , Poor iron protection effect, short holding time of hydraulic system, serious oil leakage and many other problems. Summary of the invention [0003] In order to solve the problems of poor iron protection effect of the existing four-roller crusher, short pressure holding time of the hydraulic system, and serious oil leakage, the present invention proposes a four-roller crusher hydraulic control system, which not only solves the system The pressure hol...
