(Czech Republic pusher hydraulic cylinder,produced by Hebei Hengyu company）

pusher hydraulic cylinder are widely used in Czech Republic，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed pusher hydraulic cylinder for customers from Czech Republic.

Introduction to pusher hydraulic cylinder:

If it is found that the pusher hydraulic cylinder lubrication is poor or the pusher hydraulic cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the pusher hydraulic cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the pusher hydraulic cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the pusher hydraulic cylinder center line. In this way, when the piston works in the pusher hydraulic cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the pusher hydraulic cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

In the case of serious wear on the inner surface of the pusher hydraulic cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the pusher hydraulic cylinder manufacturing process for replacement. The pusher hydraulic cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.

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 role of the pusher hydraulic cylinder in the mold industry: the pusher hydraulic cylinder has a variety of uses in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the pusher hydraulic cylinder is reasonable or more cost saving. Let the side core be extracted before opening the mold. Hot runner is mainly based on the product to decide, sometimes customers require the use of hot runner, the price is more expensive, but there are many benefits, you can save raw materials, shorten the molding cycle The pusher hydraulic cylinder has an irreplaceable role in the heavy industry production process: it is mainly used in places that need to support heavy objects for a long time, and it can still support heavy objects when the oil pressure is removed, and it is safe and reliable. Can be used underwater, single action, load reversion, nut self-locking to make the load safer, especially in large projects, is easy to operate control and self-locking jack, designed with a safety pressure retaining device, built-in pressure relief valve to prevent overload, to protect the self-locking jack to facilitate safe operation. The connection of the device is connected by high pressure hose and threaded joint, which has the advantages of fast use and overcoming the shortcomings of fast traditional joint oil leakage. It is mainly used for equipment installation and toppling operation in various industries such as electric power, construction, machinery manufacturing, mining, railway bridge, shipbuilding and so on.

Answers to some questions about pusher hydraulic cylinder:

What are the connection methods of the hydraulic cylinder? The connection modes of the cylinder and the actuator are earring connection, hinge shaft connection, thread connection, etc. The connection modes of tubing and cylinder are threaded connection, flange connection, etc.

How to deal with oil cylinder leakage?
The causes of oil leakage and treatment methods are as follows: (1) The spool is stuck or the valve hole is blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check valve body for wear. (2) The piston rod and cylinder are stuck or the hydraulic cylinder is blocked. At this time, no matter how to operate, the hydraulic cylinder does not move or moves very little. At this time, it should be checked whether the piston and piston rod seal is too tight, whether it enters the dirt and colloid precipitate: whether the shaft line of the piston rod and the cylinder is in alignment, and whether the wearing parts and seals are invalid.
