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

Introduction to trailer hydraulic cylinder:

The commonly used buffer structure of the trailer hydraulic cylinder is composed of a piston boss and a trailer hydraulic cylinder head groove. When the piston moves close to the trailer hydraulic cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

Do not regularly check the damage of the chrome layer of the trailer hydraulic cylinder: completely extend the trailer hydraulic cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the trailer hydraulic cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the trailer hydraulic cylinder seal. Welding slag is strictly prohibited on the surface of the trailer hydraulic cylinder.

trailer hydraulic cylinder hydraulic oil selection: The recommended working oil viscosity of the trailer hydraulic cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

trailer hydraulic cylinder buffer valve inspection and maintenance: For the valve buffer trailer hydraulic cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

Answers to some questions about trailer hydraulic cylinder:

What are the reasons why the hydraulic cylinder action is slower than normal?
There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system under the pressure state is consistent with the initial setting. Before measuring the pressure, it is best to check the hydraulic oil and suction oil filter and replace or clean it. Second, check the main relief valve of the reversing control multiway valve to see if there is damage or foreign matter blocking, and clean it. If your pump is a gear pump, the problem should generally be small. Second, look at traffic. There is no leakage in the cylinder, leakage in the reversing valve spool and so on.

Why does the hydraulic cylinder not return?
For a spring return cylinder, it is possible that 1, the spring is damaged. You can check it for processing. 2, the oil in the oil path is not unloaded, causing it to be unable to reset. 3, the cylinder piston is dead, resulting in no position. For double-acting cylinders, it is possible to: 1, the spool is not reversed, or is not changed to the correct position, check whether the reversing valve is normal (and whether there is electricity). 2, the cylinder piston is dead, resulting in no position, check and treatment can be. 3, the return oil pressure is insufficient, the inlet oil is not unloaded, the operation is not smooth.
