(Ireland loading cylinder,produced by Hengyu Hydraulic Co., Ltd）

loading cylinder are widely used in Ireland，because of excellent fatigue and impact resistance，smooth movement，high work efficiency.So our company has designed loading cylinder for customers from Ireland.

Introduction to loading cylinder:

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

The wear of the hard chromium plating layer of the loading cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.

loading cylinder is the most important part of construction machinery, the traditional processing method is: broaching loading cylinder block - fine boring loading cylinder block - grinding loading cylinder block. The rolling method is: broaching loading cylinder block - fine boring loading cylinder block - rolling loading cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the loading cylinder block is about 1-2 days, rolling 1 meter of the loading cylinder 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 RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the loading cylinder increases by 25%. If the loading cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality loading cylinders, you must take the rolling production process. After the loading cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

loading cylinder piston rod material selection and requirements: ① piston rod is usually made of 45 steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. The piston rod is generally designed as a loading cylinder, if the diameter is larger, the hollow piston rod can be used. Made of No. 45 seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the working surface of the rod can be plated with hard chromium. ⑥ The piston rod and the end cap are guided by H8 ' loading cylinder piston rod industry standard: piston rod diameter series of national recommended standard GB/T2348-1993. Piston rod thread size series standard GB/T2350-1980. Please refer to execute. There is no industry standard for piston rods Both the loading cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The loading cylinder mainly outputs linear motion and force. The loading cylinder has a variety of forms, according to the different characteristics of its mechanism it can be divided into piston type, plunger type and swing type three categories, according to the mode of action he can be divided into single action and double action. Piston loading cylinder, plunger loading cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger loading cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

Answers to some questions about loading cylinder:

What is the valve on the hydraulic cylinder?
Oil valve, relief valve, overload valve, explosion-proof valve, etc., these are very convenient to insert! The oil valve, the overload valve and the blasting valve are very important for larger cylinders. Manufacturers will not offer you the selection. You need to choose the values by yourself according to your system, pump, cylinder, environment, working conditions and other comprehensive consideration!

How to disassemble injection molding machine injection cylinder?
If it is not repaired for a long time, it is recommended to open both ends, comprehensively check the oil seal and piston ring inside, this is not much difficulty, pay attention to not install reverse when changing the oil seal, some piston rings are steel rings are rubber rings, and several interfaces of steel rings are not in the same position; Rubber ring pay attention not to install reverse; Be careful not to damage the oil seal when installing, otherwise it will soon leak oil.
