Description

Preparation method of outer rubber tube of tensile compression-resistant high-performance hydraulic oil pipe

Technical Field

The invention relates to the technical field of hydraulic fittings, in particular to a preparation method of an outer rubber tube of a tensile compression-resistant high-performance hydraulic oil tube.

Background

Hydraulic is a term used in the mechanical and electromechanical industries. The hydraulic pressure can be in a power transmission mode and becomes hydraulic transmission. The hydraulic pressure may also be used as a control means, called hydraulic control. The hydraulic transmission uses liquid as a working medium and utilizes the pressure energy of the liquid to transmit power. The hydraulic control is a control in which a pressure fluid is transmitted as a control signal. Control systems that are designed with hydraulic technology are referred to as hydraulic control systems. The hydraulic control generally includes hydraulic open-loop control and hydraulic closed-loop control. The hydraulic closed-loop control is also referred to as hydraulic servo control, and it constitutes a hydraulic servo system, and generally includes an electric hydraulic servo system (electro-hydraulic servo system) and a mechanical hydraulic servo system (mechanical-hydraulic servo system, or mechanical-hydraulic servo mechanism).

A complete hydraulic system consists of five parts, namely a power source device, an execution device, a control and regulation device, an auxiliary device and a liquid medium. The hydraulic pressure has the characteristics of large transmission power, easy transmission and configuration and the like, and is widely applied in industrial and civil industries. The actuators (hydraulic cylinder and hydraulic motor) of the hydraulic system function to convert the pressure energy of the fluid into mechanical energy to achieve the desired linear reciprocating or rotary motion. The energy source device (hydraulic pump) of the hydraulic system functions to convert the mechanical energy of the prime mover into pressure energy of the fluid.

The hydraulic equipment is widely applied to large-scale engineering mechanical equipment such as excavators, loaders and road rollers at present, because the working environment when the engineering mechanical equipment operates is relatively bad, a hydraulic oil pipe can be touched with external hard objects besides the oil pressure effect generated by hydraulic oil, because the tensile and compressive properties of the existing hydraulic oil pipe are weak, especially an outer rubber pipe, the service life can be shortened rapidly due to long-term negative pressure work, and the phenomenon that the outer rubber pipe of the hydraulic oil pipe is scratched or cut due to external force factors is easy to directly cause, the service life of the hydraulic oil pipe is shortened, and the normal use of the engineering mechanical equipment is directly influenced.
