(Hungary pressure plate hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to pressure plate hydraulic cylinder:

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

pressure plate hydraulic cylinder and hydraulic station selection: Select the type and structure of the pressure plate hydraulic cylinder according to the operation requirements of the main engine. According to the external load force borne by the pressure plate hydraulic cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the pressure plate hydraulic cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the pressure plate hydraulic cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the pressure plate hydraulic cylinder, the diameter of the piston and the piston rod.

After chrome plating of the piston rod of the pressure plate hydraulic cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

Protection of the pressure plate hydraulic cylinder surface: During the dismantling process, safety protection should be carried out on the pressure plate hydraulic cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the pressure plate hydraulic cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the pressure plate hydraulic cylinder should be cleaned up in time.

Answers to some questions about pressure plate hydraulic cylinder:

Why are the hydraulic cylinders out of sync? The reasons for the unsynchronous operation are as follows: 1, the deviation of the external load of the two cylinders, such as the different resistance and friction of the two cylinders will lead to imbalance. The displacement of the cylinder with low resistance will be larger. 2, the difference in internal friction, such as the difference between the piston and the cylinder of each cylinder, the friction between the piston rod and the seal causes the cylinder to be out of sync. 3. The different resistance of hydraulic oil along the pipeline of the two cylinders causes the cylinder to be out of sync. 4, the deviation of the control original adjustment causes the deviation of the flow to be out of sync, such as the use of an independent throttle valve for each cylinder will appear the difference in the flow of oil in and out of the oil affecting the synchronization of the two cylinders. 5. The cylinder support point of the supported part is initially different.

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.
