What Do The Symptoms Of The Hydraulic Valve Do Not Work?

Hydraulic valve in the course of the work will appear card valve, no pressure or pressure relief, etc., is the common symptoms of the system, like hydraulic valve components of the pollution wear: various pollutants in the oil caused by various forms of wear and tear Particles into the movement of the gap, the parts of the surface to produce cutting wear or fatigue wear. The solid particles in the high-speed liquid flow cause erosion wear on the surface of the component. Oil and oil in the oil oxidation of deterioration of the product on the component corrosion. In addition, the air in the system's oil causes cavitation, resulting in surface erosion and damage.

Hydraulic valve components are clogged and jammed Faults: solid particles block the gap and orifice of the hydraulic valve, causing the spool to block and jam, affecting work performance and even causing serious accidents. In fact, is not the valve problem, but the oil pollution and pipeline pollution caused.

System to accelerate the deterioration of oil performance: oil and water in the air with its thermal energy is the main condition of oil oxidation, and oil in the metal particles on the oil oxidation plays an important catalytic role, in addition, the oil Water and suspended bubbles significantly reduce the strength of the oil film between the movement and reduce the lubricity. So the hydraulic valve is not working properly there are many reasons.
