(Czech Republic yg series hydraulic cylinder,produced by Hengyu Group）
yg series hydraulic cylinder are widely used in Czech Republic，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed yg series hydraulic cylinder for customers from Czech Republic.
When the yg series hydraulic cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the yg series hydraulic cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.
The material, shape and compression of the yg series hydraulic cylinder seal have a great impact on the service life and work efficiency of the yg series hydraulic cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.
When purchasing the yg series hydraulic cylinder, try to clarify the following parameters of the yg series hydraulic cylinder: A. yg series hydraulic cylinder diameter, rod diameter, stroke; B. Working pressure or yg series hydraulic cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right yg series hydraulic cylinder type can be found accurately and quickly.
yg series hydraulic cylinder hydraulic oil selection: The recommended working oil viscosity of the yg series 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.
In a hydraulic system, a hydraulic pump has many hydraulic cylinders and hydraulic motors, and these executive components do not coordinate their actions with each other.
A load-sensitive variable pump can be used if these components sometimes need to work simultaneously and the power required is large. The required flow is distributed by the multi-way reversing valve, and the required flow and pressure changes are automatically adjusted by the hydraulic pump. Pressure reducing valves can be used for particularly low pressure circuits. Because you execute more components, the use of quantitative pump will cause a waste of energy, the system heat is large, not suitable.
What do cylinder internal leakage and external leakage mean?
Internal leakage means that the piston seal in the cylinder is not strict, there is a leak between the two chambers of the cylinder, the oil is still in the cylinder, and the external leakage is that the oil leaks to the outside of the cylinder.
