(Ireland automobile tailboard cylinder,produced by Hengyu Hydraulic Cylinder Factory）

automobile tailboard cylinder are widely used in Ireland，because of no need for deceleration device，long service life，smooth movement.So our company has designed automobile tailboard cylinder for customers from Ireland.

Introduction to automobile tailboard cylinder:

When the automobile tailboard cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the automobile tailboard cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

Do not enter foreign bodies when installing the automobile tailboard cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.

The main role of the automobile tailboard cylinder: the automobile tailboard cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the automobile tailboard cylinder realizes reciprocating motion. The structure of the automobile tailboard cylinder has three categories: piston automobile tailboard cylinder, plunger automobile tailboard cylinder, swing automobile tailboard cylinder, piston automobile tailboard cylinder and plunger automobile tailboard cylinder to achieve reciprocating linear motion, output speed and thrust, swing automobile tailboard cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the automobile tailboard cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The automobile tailboard cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

What kind of process is used in the automobile tailboard cylinder to make high-quality automobile tailboard cylinder products: the body is the main component of the automobile tailboard cylinder, mining single pillar, hydraulic support, gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. Body processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of body is deep hole processing, which has always troubled the processing personnel. The automobile tailboard cylinder products of our company mainly use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface micro-cracks and hinder the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the body can be improved. The correct rolling process of the automobile tailboard cylinder block: broaching block - fine boring block - grinding block. The rolling method is: broaching block - fine boring block - rolling block, the process is 3 parts, but the time is compared: grinding 1 meter of the block is about 1-2 days, rolling 1 meter of the block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3um before rolling to RA0.4-0.8&um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the automobile tailboard cylinder increases by 25%. If the service life of the automobile tailboard cylinder is only considered, it is increased by 2 to 3 times, and the efficiency of the boring and rolling process is about 3 times higher than that of the grinding process. automobile tailboard cylinder misoperation or operation failure may be caused by the following reasons, you can start from these aspects of the investigation: (1) spool stuck or valve hole blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the automobile tailboard 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 the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium. (2) The piston rod and automobile tailboard cylinder are stuck or the automobile tailboard cylinder is blocked. At this time, no matter how to manipulate, the automobile tailboard cylinder does not move or moves very little. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the automobile tailboard cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

Answers to some questions about automobile tailboard cylinder:

What is the meaning of cylinder ejection on the injection mold, and what is the difference between cylinder ejection and ordinary ejection?
Usually requires the front die ejection will use the cylinder to drive the thimble plate to achieve the ejection of the thimble. There is also a case that the mold is very large or long, and the balance of the ejector rod of the injection molding machine is not enough, and the cylinder ejector will also be used.

How to change the seal ring of lift oil cylinder of forklift truck?
Remove the cylinder, put it on the vise, first screw off the big nut plug on the head, and then pull out the guide sleeve, you can directly pull out the core of the cylinder, if it is to change the seal of the cylinder head, the core does not need to be pulled out, if it is to change the seal inside, pull it out and see the oil seal, remove it and replace it, there are three seals of the cylinder head, the inner seal, The outer seal, dustproof, it is best to replace them all together, and be sure to keep them clean when changing, and you can lubricate them with clean hydraulic oil.
