(France pusher hydraulic cylinder,produced by Hengyu Group）

pusher hydraulic cylinder are widely used in France，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed pusher hydraulic cylinder for customers from France.

Introduction to pusher hydraulic cylinder:

The definition of the minimum stable speed refers to the minimum movement speed of the pusher hydraulic cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the pusher hydraulic cylinder that undertakes different work has different requirements for the minimum stable speed.

The internal leakage of the pusher hydraulic cylinder should be prevented when the pusher hydraulic cylinder is used. The internal leakage of pusher hydraulic cylinder includes the leakage caused by excessive wear of pusher hydraulic cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.

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

If the pusher hydraulic cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the pusher hydraulic cylinder. The internal parts of the pusher hydraulic cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, and the action resistance is too large, so that the piston speed of the pusher hydraulic cylinder changes with the different stroke position, and there is slip or crawl. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the pusher hydraulic cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings. At the same time, check whether the lubrication is good or whether the pusher hydraulic cylinder bore processing is out of whack. Because the piston and pusher hydraulic cylinder, guide rail and piston rod are relative If the pusher hydraulic cylinder is crawling seriously, check whether air has entered the hydraulic system. Air compression or expansion can cause the piston to slip or crawl. The exclusion measures are to check the hydraulic pump, set up a special exhaust device, and quickly operate the exhaust several times in the full stroke. Check the seals at the same time, because the quality of the seals is directly related to slippage or crawling. When the O-ring is used under low pressure, compared with the U-ring, it is easy to slip or crawl because of the higher surface pressure and the larger difference between static and static friction resistance. The surface pressure of the U-shaped sealing ring increases with the increase of pressure, although the sealing effect is correspondingly improved, but the difference between static and static friction resistance is also larger, the internal pressure increases, affecting the rubber elasticity, due to the increase in the contact resistance of the lip, the sealing ring will tip over and the lip elongation, and it is also easy to cause slip or crawling pusher hydraulic cylinder weight composition and calculation. The weight of the pusher hydraulic cylinder is composed of the pusher hydraulic cylinder diameter, the outer diameter and weight of the pusher hydraulic cylinder, the rod diameter, and the weight of the accessories, so in calculation, it is to add all these together to get the specific value. However, if there are special circumstances, it may be calculated separately. This work can be carried out by yourself, but it can also be carried out by professionals, so that mistakes can be avoided.

Answers to some questions about pusher hydraulic cylinder:

How to calculate the tonnage of the hydraulic press without konowing the diameter of the cylinder?
To know the tonnage of the hydraulic cylinder, you first need to know the working pressure of the hydraulic system, the inner diameter of the hydraulic cylinder and the outer diameter of the cylinder rod (the outer diameter of the cylinder rod is needed when calculating the hydraulic cylinder tension). The thrust of the hydraulic cylinder (that is, the force that the hydraulic cylinder can produce by extending out) = the cross-sectional area of the hydraulic cylinder (or the cross-sectional area of the piston) × the working pressure of the cylinder (the cross-sectional area of the piston) =pi*D^2/4= PI (take 3.14) × the square of the cross-sectional area of the piston ÷4 working pressure to see the pressure displayed on the pressure gauge when the maximum load is working.

How to calculate the cylinder diameter, rod diameter and pressure of the cylinder, and how to output tonnage?
Hydraulic cylinder output force F=PAX10^3(KN) F is the output force (KN), P working pressure (MPa), A is the piston or plunger area of action.
