(Hungary sanitation truck hydraulic cylinder,produced by Hebei Hengyu company）

sanitation truck hydraulic cylinder are widely used in Hungary，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed sanitation truck hydraulic cylinder for customers from Hungary.

Introduction to sanitation truck hydraulic cylinder:

When the sanitation truck hydraulic cylinder is customized, if there are high requirements for the quality of the sanitation truck hydraulic cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the sanitation truck hydraulic cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the sanitation truck hydraulic cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

When the sanitation truck hydraulic cylinder is installed, the piston and the sanitation truck hydraulic cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the sanitation truck hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the sanitation truck hydraulic cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized sanitation truck hydraulic cylinders, only careful and careful operation can be avoided.

The assembly work of the sanitation truck hydraulic cylinder has a great impact on the quality of the sanitation truck hydraulic cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.

The sanitation truck hydraulic cylinder should be vented: when the sanitation truck hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the sanitation truck hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the sanitation truck hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the sanitation truck hydraulic cylinder, the oil is best entered and discharged from the highest point of the sanitation truck hydraulic cylinder. sanitation truck hydraulic cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

Answers to some questions about sanitation truck hydraulic cylinder:

Does the sealing string of the upper and lower chamber of the hydraulic cylinder fall by itself?
It is possible, the probability accounts for 85% (depending on the weight), the weight is less than the system resistance, may not fall, the weight is greater than the system resistance, will not necessarily fall, so often check the equipment, safety first, find the problem in time to solve, the cylinder is not very expensive parts, maintenance does not cost much money, However, accidents caused by cylinder failure will lose several times the cost.

How to calculate the hydraulic cylinder pressure? How much pressure can put up how much weight?
If you want to calculate the pressure of the cylinder, you must know the inner diameter of the cylinder, if the piston rod is needed to lift the weight, it should be: cylinder (no piston rod end) pressure = load (4000N) ÷{(PI /4)X the square of the cylinder diameter (mm) ", it has nothing to do with the piston rod diameter, the rod diameter of the piston rod is only related to the stability of the cylinder. The pressure inside the cylinder should be p=F/S=400×10/(3.14×(0.5×25)×(0.5×25))=8.15MPa which means that you need to provide at least that much pressure to complete the operation.
