(Spain pusher hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

pusher hydraulic cylinder are widely used in Spain，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed pusher hydraulic cylinder for customers from Spain.

Introduction to pusher hydraulic cylinder:

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.

The repair method of pusher hydraulic cylinder wear: 1. Metal repair material is applied to the scratched surface; The first layer should be thin, uniform and fully covered with the scratched surface to ensure the best adhesion between the material and the metal surface, and then apply the material to the entire repair site and press repeatedly to ensure that the material is filled and reaches the required thickness, so that it is slightly higher than the surface of the guide rail; 2, the material at 24℃ to fully achieve the performance of 24 hours, in order to save time, can be through the tungsten halogen lamp to increase the temperature, the temperature rises 11℃, the curing time will be reduced by half, the best curing temperature 70℃; 3. After the material is cured, use a fine grinding stone or a scraper to repair and smooth the material higher than the surface of the guide rail, and the construction is completed.

The pusher hydraulic cylinder is not the same as the pusher hydraulic cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the pusher hydraulic cylinder can not be used as a high-power power component, but the pusher hydraulic cylinder can be used as a relatively large power component, or the pusher hydraulic cylinder system can be used.

When the hydraulic oil is not pumped into the pusher hydraulic cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the pusher hydraulic cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

Answers to some questions about pusher hydraulic cylinder:

Hydraulic cylinder application areas?
1, in the machine tool industry, 85% of the machine tool transmission system adopts hydraulic transmission and control. Such as grinding machine, milling machine, planer, broaching machine, press, shearing machine, and combined machine tools. 2, in the metallurgical industry, electric furnace control system, rolling mill control system, open furnace charging, converter control, blast furnace control, strip deviation and constant tension device are all using hydraulic cylinders. 3, in the construction machinery, the general use of hydraulic transmission, such as excavators, tire loaders, truck cranes, crawler bulldozers, tire cranes, self-propelled scrapers, graders and vibration rollers. 4, in agricultural machinery, the use of hydraulic cylinders is also widely used, such as combine harvesters, tractors and so on.

What valve is used to control the speed of the cylinder?
Hydraulic cylinder for lifting is generally the piston rod downward installation, to achieve the fast and slow speed of the cylinder, you can add a two-digit three-way electromagnetic reversing valve + a throttle valve on a branch at the bottom of the cylinder, you can achieve speed change, control mode can be controlled by time control can also be controlled by stroke switch. If you want to achieve more accurate control can use proportional valve control.
