(Pakistan construction machinery hydraulic cylinder,produced by Hebei Hengyu company）

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

Introduction to construction machinery hydraulic cylinder:

Most of the failure of the construction machinery hydraulic cylinder is because there is a foreign body in the construction machinery hydraulic cylinder into the failure of the construction machinery hydraulic cylinder, the most problematic is that it is difficult to determine when the foreign body is into the construction machinery hydraulic cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

When purchasing the construction machinery hydraulic cylinder, try to clarify the following parameters of the construction machinery hydraulic cylinder: A. construction machinery hydraulic cylinder diameter, rod diameter, stroke; B. Working pressure or construction machinery 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 construction machinery hydraulic cylinder type can be found accurately and quickly.

Before purchasing the construction machinery hydraulic cylinder, it is necessary to master the original information and design basis, mainly including: the use and working conditions of the machine; The structural characteristics, load conditions, stroke size and operation requirements of the working mechanism; The selected working pressure and flow of the hydraulic system; The reality of materials, fittings and processes; Relevant national standards and technical specifications, etc.

When the construction machinery 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 construction machinery 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.

Answers to some questions about construction machinery hydraulic cylinder:

How to make 4 cylinders balance lifting weight at the same time?
The cost of the synchronous valve is lower, 4 cylinders need 3 synchronous valves, to be precise you can use a synchronous motor, but it is more expensive. There is another way, that is to install a throttle valve in each cylinder, respectively adjust the speed of the 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.
