road paving machine hydraulic cylinder are widely used in Estonia，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed road paving machine hydraulic cylinder for customers from Estonia.

Introduction to road paving machine hydraulic cylinder:

The material, shape and compression of the road paving machine hydraulic cylinder seal have a great impact on the service life and work efficiency of the road paving 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 road paving machine hydraulic cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the road paving machine hydraulic cylinder should pay attention to: the operation should be as far away from the road paving machine hydraulic cylinder as possible, to avoid falling objects, knocking, rubbing the road paving machine hydraulic cylinder coating. When cleaning the road paving machine hydraulic cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the road paving machine hydraulic cylinder when the oil temperature exceeds 70 ° C.

The pressure of the sliding surface of the road paving machine hydraulic cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the road paving machine hydraulic cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.

Most of the failure of the road paving machine hydraulic cylinder is because there is a foreign body in the road paving machine hydraulic cylinder into the failure of the road paving machine hydraulic cylinder, the most problematic is that it is difficult to determine when the foreign body is into the road paving machine hydraulic cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

Answers to some questions about road paving machine hydraulic cylinder:

How big is the pump and motor for 20 tons of hydraulic cylinder?
According to the working pressure of 25 mpa estimate, the cylinder should use 100mm bore, 63mm piston rod, stroke 40mm. According to 30 reciprocating calculation, the flow rate is about 25 liters/minute. The motor power is 11 kW, want to be cheap, use 25SCY14-1B oil pump can be.

What is hydraulic cylinder guide?
The cylinder itself can not move, the piston moves, the guide should be used to guide the mechanism connected with the piston extension end. For example, in the commonly used hydraulic press, the guide column above is used to guide the pressure plate connected with the piston.
