(Singapore clamp type cylinder,produced by Hengyu Hydraulic Co., Ltd）

clamp type cylinder are widely used in Singapore，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed clamp type cylinder for customers from Singapore.

Introduction to clamp type cylinder:

clamp type cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards clamp type cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the clamp type cylinder guide is determined by the length of the stroke. Check the strength of clamp type cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

If the clamp type 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 clamp type cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow clamp type cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the clamp type cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the clamp type cylinder includes the leakage caused by excessive wear of the clamp type 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 clamp type cylinder, and the phenomenon of "pulling the clamp type cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

The clamp type cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure clamp type cylinder can use 20 steel pipe, and the high pressure clamp type cylinder can use 45 steel pipe.

There are some honeycomb holes in the inner wall of the clamp type cylinder, piston or piston rod surface. How is this formed? When we repair the clamp type cylinder, we can see that there are some honeycomb holes on the inner wall of the clamp type cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the clamp type cylinder is targeted to prevent. Is very necessary.

Answers to some questions about clamp type cylinder:

To achieve the same stroke, which is better, hydraulic cylinder or lead screw?
If there is batch action, then the hydraulic pressure is better. Hydraulic: smooth operation, no lubrication, easy control, high control accuracy (can use proportional or servo system), the key is to manually control, but certainly to support the hydraulic system, for a single action must cost. Maintenance costs are also high. Lead screw: simple structure, easy to achieve, convenient maintenance, but must be lubricated, can not be manual, or manual control is inconvenient. See where it is used, if it is used in high-precision occasions, it must only be hydraulic, because the lead screw has a gap. There are many hydraulic actions, the hydraulic system itself must be prepared, then the use of hydraulic pressure is also very economical.

How to take out the diaphragm of hydraulic cylinder? The septum ring is also known as the septum sleeve, when the cylinder is too long, and does not need too much travel, add the septum sleeve, limit the stroke of the hydraulic cylinder, set on the piston rod, only contact with the guide sleeve and piston, do not cooperate with the cylinder, limit the stroke, take out the difficulty is different, need to have such a professional tool, before taking out to consult the manufacturer.
