Czech Republic hydraulic cylinder,punch machine hydraulic cylinder manufacturer,punch machine hydraulic cylinder(Czech Republic punch machine hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
punch machine hydraulic cylinder are widely used in Czech Republic,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed punch machine hydraulic cylinder for customers from Czech Republic.
There are some honeycomb holes in the inner wall of the punch machine hydraulic cylinder, piston or piston rod surface. How is this formed? When we repair the punch machine hydraulic cylinder, we can see that there are some honeycomb holes on the inner wall of the punch machine hydraulic cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the punch machine hydraulic cylinder is targeted to prevent. Is very necessary.
Piston punch machine hydraulic cylinder is widely used in hydraulic transmission. When the punch machine hydraulic cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the punch machine hydraulic cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the punch machine hydraulic cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.
When the punch machine hydraulic cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the punch machine hydraulic cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the punch machine hydraulic cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the punch machine hydraulic cylinder can meet the requirements by grinding. However, the life and reliability of this repair punch machine hydraulic cylinder are not high.
punch machine hydraulic cylinder use should try to avoid sealing belt into the punch machine hydraulic cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the punch machine hydraulic cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the punch machine hydraulic cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.
Is there a national standard for the testing of hydraulic cylinders?
Generally speaking, the cylinder test is carried out according to JB/JQ20302 Allowable leakage of cylinder in pre-factory leakage test. GB2879 hydraulic cylinder piston and piston rod dynamic seal groove type, size and tolerance. GB6578 hydraulic cylinder piston rod dust ring groove type, size and tolerance. GB7938 hydraulic cylinder and cylinder nominal pressure series, etc.
How to distinguish loader boom and forearm hydraulic cylinder? Is it the upper arm or the lower arm?
The one in the middle that can flip the bucket is the small arm cylinder you say, and the one that lifts the brackets (big arms) on both sides is the big arm cylinder.
