column information in the field of hydraulic machinery, relying on friends [20 years] industry deep plowing experience, focus on the output of hydraulic technology innovation, market trends, application cases and other high value content. With the aim of "professional, timely and deep", we provide one-stop information service for engineers, purchasing decision makers and industry researchers, helping users to accurately grasp the pulse of hydraulic technology development.
The reason why the power of the 200-ton single-arm hydraulic press is blocked: the most likely reason is that the plunger head of the single-arm hydraulic press is broken or the bearing in the pump falls off the pump. although the plunger head is made of metal, it breaks under the huge pressure in the pump of the single-arm hydraulic press...

The leakage of the hydraulic pump of the 500-ton hydraulic press refers to the leakage of the hydraulic oil. In the work project, almost all hydraulic pumps will have similar problems. Its appearance will not immediately stop the operation of mechanical equipment, but it will reduce the capacity of the hydraulic pump of the hydraulic press...

Reasons for Excessive Downward Pressure of 1. 1. Excessive Support Pressure of 500 Ton Hydraulic Press; 2. The sealing ring of the hydraulic cylinder leaks oil. 3. The preset pressure of the pilot valve is too small; 4. Poor sealing of the cartridge valve port; 5. There is air in the oil circuit of the pressure gauge;...

1. Check whether the stretching hydraulic oil pump, control valve and pressure gauge are normal and whether the oil temperature is within the allowable range; 2. Check whether the mold has cracks and whether the fastening screws are loose; 3. Turn on the power switch of the hydraulic machine and start the cooling circulation motor; 4,...

For hydraulic equipment with different working characteristics, the requirements for oil temperature are also different. In general, the working temperature of the oil is between 30-60 ℃. For the high pressure system or program control system of hydraulic equipment, in order to reduce leakage, in order to ensure...
