punch machine hydraulic cylinder are widely used in Bulgaria，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed punch machine hydraulic cylinder for customers from Bulgaria.

Introduction to punch machine hydraulic cylinder:

Classification of punch machine hydraulic cylinder: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.

The material, shape and compression of the punch machine hydraulic cylinder seal have a great impact on the service life and work efficiency of the punch machine hydraulic cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.

The punch machine hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the punch machine hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The punch machine hydraulic cylinder is basically composed of punch machine hydraulic cylinder and punch machine hydraulic cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.

If the punch machine hydraulic cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the punch machine hydraulic cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow punch machine hydraulic cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the punch machine hydraulic cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the punch machine hydraulic cylinder includes the leakage caused by excessive wear of the punch machine hydraulic cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and punch machine hydraulic cylinder, and the phenomenon of "pulling the punch machine hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

Answers to some questions about punch machine hydraulic cylinder:

How to change the seal ring of lift oil cylinder of forklift truck?
Remove the cylinder, put it on the vise, first screw off the big nut plug on the head, and then pull out the guide sleeve, you can directly pull out the core of the cylinder, if it is to change the seal of the cylinder head, the core does not need to be pulled out, if it is to change the seal inside, pull it out and see the oil seal, remove it and replace it, there are three seals of the cylinder head, the inner seal, The outer seal, dustproof, it is best to replace them all together, and be sure to keep them clean when changing, and you can lubricate them with clean hydraulic oil.

What brand of hydraulic cylinder seal ring is best?
Depending on the specific product, the world famous seal brands are NOK, CFW, PARKER, TSS, WKF, DINGZING DZ, ASTON, HALLITE, TECNOLAN and so on.
