(Kenya road paving machine hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）
road paving machine hydraulic cylinder are widely used in Kenya，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed road paving machine hydraulic cylinder for customers from Kenya.
After chrome plating of the piston rod of the road paving machine hydraulic cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.
If it is found that the road paving machine hydraulic cylinder lubrication is poor or the road paving machine hydraulic cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the road paving machine hydraulic cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the road paving machine hydraulic cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the road paving machine hydraulic cylinder center line. In this way, when the piston works in the road paving machine hydraulic cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the road paving machine hydraulic cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.
When using the road paving machine hydraulic cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the road paving machine hydraulic cylinder block. If the road paving machine hydraulic cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the road paving machine hydraulic cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the road paving machine hydraulic cylinder, so that the working efficiency of the road paving machine hydraulic cylinder is reduced.
When the road paving machine hydraulic cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.
What's the use of three oil pipes on the cylinder?
The cylinder usually has an upper and lower oil chamber, one is connected to the upper oil chamber, one is connected to the lower oil chamber, sometimes a hydraulic lock will be added, that is, a hydraulic control check valve to prevent accidents when the oil pipe breaks, so the third pipe should be the control oil pipe of the hydraulic control check valve.
What is the main maintenance of the cylinder?
After disassembling the cylinder: 1, clean the cylinder and piston; 2, replace all seals; 3, if there is a valve to repair, to ensure sealing and flexible; 4, deal with all deformation parts; 5. Installation experiment.
