The Hydraulic Cartridge Counterbalance Valve has no repair for more than 1 year,
:
Consuelo is from a hydraulic equipment manufacturing company in Spain, and has been engaged in procurement for less than 3 years. At the beginning of last year, their excavator was complained. After checking, it was judged that the hydraulic cartridge counterbalance valve was leaking, and the valve spool was worn. According to the feedback from the original hydraulic cartridge counterbalance valve manufacturer, the valve spool is made of 12L14 free-cutting steel, which is commonly used in the industry. The only solution is to replace the hydraulic cartridge counterbalance valve with new ones, which means that the valves will need to be replaced every 8 months. Consuelo knew that his boss and customer would not be satisfied. He tried to find a new manufacturer of hydraulic cartridge counterbalance valve, but failed.
Consuelo found AAK on Google, and noticed that AAK had introduced some customer cases about the difficult and complicated problems of the hydraulic cartridge counterbalance valve, and sent an email asking: Can AAK hydraulic cartridge counterbalance valve achieve no internal leakage and be durable for more than 1 year? After communication, we learned that the hydraulic cartridge counterbalance valve produced by the original cartridge valve manufacturer had internal leakage after being used for about 8 months. According to the schematic diagram of the hydraulic system provided by Consuelo, combined with the working conditions of the excavator, AAK engineers found that it was not only the problem of changing the material of the valve spool, but also the problem of optimizing the structure of the original hydraulic cartridge counterbalance valve. After 40 days, AAK sent 6 samples of hydraulic cartridge counterbalance valve.
Last week, Consuelo said that he would purchase 120 hydraulic cartridge counterbalance valves to replace the ones currently used on the excavators. The excavators installed with AAK hydraulic cartridge counterbalance valve have been used for 10 months, and there is no complaint of leakage. AAK improved the original hydraulic cartridge counterbalance valve from the 3 aspects:
1. Change in material selection. AAK hydraulic cartridge counterbalance valve spool is made of 20CrNi2MoV high carburized bearing steel, which is more suitable. We never consider the general standard of the industry, but what material is most suitable for the working condition.
2. The change of the seal, the inner cone of the check valve spool and the lower end face of the valve seat form a line seal, the outer cone of the control valve spool and the through hole on the valve seat form a line seal, and the lower through hole section of the relief valve spool and the valve seat form a line seal. Three lines are sealed to ensure no leakage.
