Costa Rica hydraulic cylinder,lift car cylinder manufacturer,lift car cylinder

(Costa Rica lift car cylinder,produced by Hebei Hengyu company）

lift car cylinder are widely used in Costa Rica，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed lift car cylinder for customers from Costa Rica.

Introduction to lift car cylinder:

In use, the lift car cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the lift car cylinder.

The material, shape and compression of the lift car cylinder seal have a great impact on the service life and work efficiency of the lift car 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.

lift car cylinders in series, parallel and series parallel. Series: In the lift car cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the lift car cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the lift car cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the lift car cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.

When installing the lift car cylinder, the axial ends of the lift car cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the lift car cylinder, there is axial expansion. If the two ends of the lift car cylinder are fixed, all parts of the lift car cylinder will be deformed. When disassembling the lift car cylinder, it is strictly forbidden to hammer the lift car cylinder and the piston surface, such as the lift car cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

Answers to some questions about lift car cylinder:

What is st represented in the cylinder formula?
St is the original unit of kinematic viscosity, the abbreviation of Stokes, that is, Stokes, short for S. cm2/s has now been used. 1 s (St) = 10^-4m2/s.

What are the four cylinders of the truck crane?
The four cylinders of the truck crane generally refer to the telescopic cylinder of the boom (to adjust the length of the boom), the variable amplitude cylinder of the boom (to adjust the elevation Angle of the boom), the horizontal telescopic cylinder of the support leg and the vertical cylinder of the support leg.
