(Tanzania road paving machine hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to road paving machine hydraulic cylinder:

When the road paving machine hydraulic cylinder is in use, ensure that the road paving machine hydraulic cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.

When the road paving machine hydraulic cylinder needs to be stored for a period of time, please follow the recommended methods: The road paving machine hydraulic cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the road paving machine hydraulic cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil road paving machine hydraulic cylinder should not be in direct contact with water vapor for a long time. The road paving machine hydraulic cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the road paving machine hydraulic cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the road paving machine hydraulic cylinder Before working, the road paving machine hydraulic cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the road paving machine hydraulic cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the road paving machine hydraulic cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

Do not enter foreign bodies when installing the road paving machine hydraulic cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.

Answers to some questions about road paving machine hydraulic cylinder:

How to calculate the tonnage of the hydraulic press without konowing the diameter of the cylinder?
To know the tonnage of the hydraulic cylinder, you first need to know the working pressure of the hydraulic system, the inner diameter of the hydraulic cylinder and the outer diameter of the cylinder rod (the outer diameter of the cylinder rod is needed when calculating the hydraulic cylinder tension). The thrust of the hydraulic cylinder (that is, the force that the hydraulic cylinder can produce by extending out) = the cross-sectional area of the hydraulic cylinder (or the cross-sectional area of the piston) × the working pressure of the cylinder (the cross-sectional area of the piston) =pi*D^2/4= PI (take 3.14) × the square of the cross-sectional area of the piston ÷4 working pressure to see the pressure displayed on the pressure gauge when the maximum load is working.

How to calculate cylinder pressure?
Hydraulic pressure area of cylinder × hydraulic pressure = output force of cylinder 200mm=20cm 100mm=10cm 15Mpa=150Kg/cm2 Cylinder thrust: 3.14×10×10 area ×150 pressure =47100Kg=47.1t cylinder pulling force: 3.14×(10×10-5×5) Area ×150 pressure =35325Kg=35.325t The above calculation did not consider the resistance of oil return, because you did not provide oil return pressure. But the impact should be small.
