(Angola road paving machine hydraulic cylinder,produced by Hebei Hengyu company）

road paving machine hydraulic cylinder are widely used in Angola，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed road paving machine hydraulic cylinder for customers from Angola.

Introduction to road paving machine hydraulic cylinder:

The viscosity of the working oil used in the road paving machine hydraulic cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

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.

When the hydraulic oil is not pumped into the road paving machine hydraulic cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the road paving machine hydraulic cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

We can not just consider the price and ignore the quality when we purchase the road paving machine hydraulic cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the road paving machine hydraulic cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the road paving machine hydraulic cylinder is not required.

Answers to some questions about road paving machine hydraulic cylinder:

How to produce good quality hydraulic cylinder?
According to the principle of quality control, it is considered from five aspects: people, machine, material, method and environment. 1, People, refers to the processing and assembly operators. Their skills, professional qualifications, literacy should meet the requirements of production. For example, do your machining workers have the required grade certificate? Do your welders have welding certificate? 2, Machine, refers to your production equipment. Production cylinders have requirements for processing equipment. For example, the piston rod requires chrome grinding. Can your equipment meet the need? 3, Material. The material you use should meet the quality requirements. For example, the sealing ring of PARK and domestic goods is different. Material is also very important. 4. Method refers to the process method. Do your processing and assembly processes meet the requirements? 5, Environment. The environment shall be neat and orderly, clean and hygienic. It is especially important for the hydraulic cylinder production enterprise environment. Can your assembly shop site be clean and dust-free? Quality inspection is also a focus of control. Products should do pressure test, leakage test. The test pressure should reach 1.25 times the design pressure. If you can't maintain pressure, what about quality? You may not be able to do the whole process of cylinder production, you can take the method of OEM. Taking advantage of the strengths of specialized manufacturers, you contract out what you need and then assemble it yourself. But the principle of quality control is the same.

There are four cylinders in the front top of the dump truck. When the second cylinder is lifted to half the height, it suddenly falls back more than 30 cm or so, and the cylinder continues to lift.
The problem is the cylinder, the second section of the different strength of the heart. When the oil supply resistance is small, the first out, when the power is not moving, the cylinder needs to be strong, because the second section needs to pop it out after a while when the pressure is large, the oil can not keep up, so it falls back, and the oil continues to keep up.
