(Peru road paving machine hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

road paving machine hydraulic cylinder are widely used in Peru，because of no need for deceleration device，long service life，smooth movement.So our company has designed road paving machine hydraulic cylinder for customers from Peru.

Introduction to road paving machine hydraulic cylinder:

Before the road paving machine hydraulic cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.

road paving machine hydraulic cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.

The quality of the road paving machine hydraulic cylinder can not be ignored in the purchase of the road paving machine hydraulic cylinder. The road paving machine hydraulic cylinder is the main component of the road paving machine hydraulic cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. road paving machine hydraulic cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of road paving machine hydraulic cylinder is deep hole processing, which has always troubled the processing personnel.

When producing oil road paving machine hydraulic cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

Answers to some questions about road paving machine hydraulic cylinder:

Classification and application of cylinders.
Hydraulic cylinder is divided into single acting hydraulic cylinder, double acting cylinder, combined hydraulic cylinder, swing hydraulic cylinder. Single acting cylinder is divided into plunger type hydraulic cylinder, single piston rod hydraulic cylinder, double piston rod hydraulic cylinder, telescopic hydraulic cylinder. Plunger type hydraulic cylinder: the plunger moves only in one direction, and the return stroke is to push the plunger back using its own weight or load. Single piston rod hydraulic cylinder: The piston moves only in one direction, and the return stroke is to push the plunger back using dead weight or load. Double piston rod hydraulic cylinder: both sides of the piston are equipped with piston rods, and pressure oil can only be supplied to one side of the piston. The return stroke usually uses spring force, gravity or external force. Telescopic hydraulic cylinder: It obtains long stroke with short cylinder. The hydraulic oil is pushed out from large to small section by section, and the external force is reduced from small to large.

How to remove the lifting cylinder from the forklift truck?
The lifting cylinder is generally fixed on the door frame, and there are screws under and above it, and it is OK to loosen the screws with a wrench on the top. However, we must pay attention to ensure safety and prevent damage to the cylinder or safety accidents.
