Hydraulic mechanical equipment with foreign matter removing and preheating functions

Abstract

The invention relates to the technical field of hydraulic mechanical equipment, in particular to hydraulic mechanical equipment with foreign matter removing and preheating functions, which comprises a hydraulic cylinder body, a front heating box corresponding to a first guide pipe is arranged on the front side of the end part of the hydraulic cylinder body, and a rear heating box corresponding to a second guide pipe is arranged on the rear side of the end part of the hydraulic cylinder body. The front heating box and the rear heating box are located on the outer sides of the first guide pipe and the second guide pipe correspondingly, so that hydraulic oil entering the hydraulic cylinder body can be preheated in advance, the hydraulic oil reaches the optimal working temperature, and the situation that the viscosity of the hydraulic oil is large due to the too low temperature is prevented; according to the hydraulic oil cylinder, the effect of poor flowability caused by the fact that the hydraulic oil cylinder enters the oil cylinder is achieved, the initial action of the hydraulic mechanical equipment is prevented from being too slow, the working efficiency of the hydraulic mechanical equipment is guaranteed, foreign matter in the hydraulic oil entering the oil cylinder is removed and filtered through the foreign matter removing assembly, and internal foreign matter removing convenience can be high through the foreign matter removing filter element.

Description

technical field [0001] The invention relates to the technical field of hydraulic mechanical equipment, in particular to a hydraulic mechanical equipment with functions of foreign matter removal and preheating. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. It is mainly used to realize reciprocating motion. It has a certain deceleration ability, no transmission gap, and the movement is relatively stable. The normal working oil temperature of the existing hydraulic cylinder is about 40 degrees Celsius, but the existing hydraulic cylinder. The starting oil temperature is generally lower than 40 degrees Celsius, and in the case of low temperature, the viscosity of the hydraulic oil is high and the fluidity is poor, which leads to the slow initial movement of the hydraulic cylinder and affects the working eff...

AI Technical Summary

Problems solved by technology

It has a simple structure and reliable operation. It is mainly used to realize reciprocating motion. It has a certain deceleration ability, no transmission gap, and the movement is relatively stable. The normal working oil temperature of the existing hydraulic cylinder is about 40 degrees Celsius, but the existing hydraulic cylinder. The starting oil temperature is generally lower than 40 degrees Celsius, and in the case of low temperature, the viscosity of the hydraulic oil is high and the fluidity is poor, which leads to the slow initial movement of the hydraulic cylinder and affects the working efficiency of the existing hydraulic cylinder. Not only that, the existing hydraulic Foreign matter will enter the cylinder, and the foreign matter is easily caught between the piston and the inner wall of the hydraulic cylinder body, resulting in scratches on the inner wall of the cylinder body, resulting in a decrease in the sealing performance of the existing hydraulic cylinder

[0003] Most of the existing hydraulic cylinders use pre-heating and pre-filtering of the hydraulic oil to achieve the normal operation of the hydraulic cylinder, but the filtering effect is poor during the oil supply process, and the heating effect is low. Affects the normal use efficiency of hydraulic machinery, so a hydraulic mechanical device with foreign body removal and preheating functions is needed to improve the above problems
