road paving machine hydraulic cylinder are widely used in America，because of clever hydraulic energy conversion，excellent temperature resistance，simple structure and reliable operation.So our company has designed road paving machine hydraulic cylinder for customers from America.

Introduction to road paving machine hydraulic cylinder:

The road paving machine hydraulic cylinder requires that the filtration accuracy of the system is not less than the 80um, and the oil pollution should be strictly controlled, the oil should be kept clean, the performance of the oil should be checked regularly, and the necessary fine filtration and replacement of new working oil should be carried out.

In the process of using the road paving machine hydraulic cylinder, sometimes such a problem will occur, the road paving machine hydraulic cylinder can not act immediately after the instruction of the road paving machine hydraulic cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil road paving machine hydraulic cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

The road paving machine hydraulic cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the road paving machine hydraulic cylinder, bite. Elimination method: When installing the road paving machine hydraulic cylinder, ensure that the axis position of the road paving machine hydraulic cylinder is consistent with the direction of movement; Make the load borne by the road paving machine hydraulic cylinder as far as possible through the road paving machine hydraulic cylinder axis, to avoid the phenomenon of eccentricity.

The material of the sliding part of the road paving machine hydraulic cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

Answers to some questions about road paving machine hydraulic cylinder:

Injection molding machine die thimble on the side of the feed nozzle, the oil cylinder pull the thimble shift, how to debug the oil cylinder?
The cylinder is connected with the neutron of the injection molding machine, the neutron is retreated after the opening mold is in place, the cylinder taps the thimble plate to the top, and then takes, and the neutron is reset.

How to achieve hydraulic cylinder self-locking?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil self-locking is equipped with a valve to maintain pressure, so that the hydraulic oil of the cylinder does not return to the tank, and the oil chamber of the cylinder is filled with a certain pressure of oil. However, this pressure holding self-locking is not very safe and reliable, and the plunger will slowly return if there is a leak. Mechanical self-locking is to install a nut on the plunger of the cylinder, and when the cylinder rises to the required position, the nut on the cylinder plunger is rotated to the end, and the cylinder block is in contact, so that the plunger will be fixed to the required height. When it is necessary to relieve the pressure, screw the nut on again and let the plunger return to the position. This kind of cylinder has a special name, called self-locking hydraulic cylinder.
