What is the fault of hydraulic wrench caused by oil pollution?Air Concrete chain saw
source:Industry News release time:2021-09-24 Article author:Rosit Popular:Air band saw
The quality of the hydraulic wrench is not only related to the rationality of the product design, but also related to the quality of the product. When using various hydraulic wrenches, if oil infection occurs, it will directly affect the normal operation of hydraulic systems, and directly cause the availability and duration of use of the hydraulic wrench. According to statistics, about 70% of hydraulic wrench system faults at home and abroad are caused by oil stains. So, what is the fault of hydraulic wrench caused by oil pollution?
(1) It will cause infection and wear of components (a basic type of component failure).
Various infectious agents in the oil will cause various forms of hydraulic wrench component wear: solid particles enter the gap, cutting wear and fatigue wear on the surface of the parts; on the surface of the solid particles that cause the high-speed flow of the components Influence: The product of oxygen (Oxygen) of water and oil that is corroded by the oil of the component. In addition, the air in the fluid of the hydraulic wrench system can cause cavitation and cause erosion and vandalism on the surface of the component.
(2) Causes component blockage and clamping failure. Hydraulic wrench is the abbreviation of hydraulic torque wrench. It is a professional bolt tightening tool that is powered by hydraulic pressure and provides high torque output. It is used for bolt installation and disassembly. It is often used to tighten and loosen bolts larger than one inch. The hydraulic wrench is composed of a working head, a hydraulic pump and a high-pressure oil pipe.
The solid particles block the gaps and holes of the hydraulic valve, causing the valve core (subordinate to the valve body) to block or block, affect the performance of the valve, and even cause serious accidents.
(3) Accelerate the deterioration of petroleum performance
The heat (Heat) of hydraulic oil in water and air is the main condition for oil liquid oxygen (Oxygen), and the oxidation of metal particles plays an important role in catalyzing the oil in the oil. In addition, the oil in the oil Water and suspended bubbles greatly reduce the strength of movement between the oil films and reduce the lubrication performance.
