Hydraulic machinery industry information, Ding run hydraulic pressure machine is your choice of pressure protection.

What is the difference between hydraulic press and common mechanical press?

2017年2月9日
Mechanical advantages and disadvantages: 1 mechanical speed 2 stroke precision, adjust the mold spacing will not change 3 up and down stroke is due to the rotation of the crankshaft driven by mechanical and adjustable distance 4 because it is pure mechanical, there will be no pressure protection, if not properly adjusted, easy to damage the machine or mold Advantages and disadvantages of hydraulic press: 1 compared to the mechanical speed is slow 2 dead in addition to the use of hard cushion out

Four column hydraulic pressure test system

2016年12月24日
The arrival of the new hydraulic machine procurement after installation, and then performance, various technical indicators meet the predetermined criteria, the use of hydraulic machine will play its value in the day after today, Libang Xiaobian experience sharing: hydraulic machine core function of hydraulic system pressure test Four aspects: 1, we should pay attention to the test pad block in the middle position of the table; 2, in accordance with the nominal pressure hydraulic machine equipme

Causes of reduced pressure

2014年4月22日
1- pressure regulating valve spring loose, such as pressure did not change after the valve may be used for a long time due to wear and tear caused by leakage can not afford pressure 2- hydraulic pump wear leakage for a long time 3- hot oil temperature is too high, the hydraulic oil is too thin can not afford high pressure 4- oil cylinder piston head seal wear or aging caused by oil and can not afford pressure 5- solenoid valve used for too long, spool wear, leakage caused by the pressure is not
