(Nepal earring type cylinder,produced by Hebei Hengyu company）

earring type cylinder are widely used in Nepal，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed earring type cylinder for customers from Nepal.

Introduction to earring type cylinder:

The earring type cylinder should be vented: when the earring type cylinder is installed or parked for a long time to work again, the air will penetrate into the earring type cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the earring type cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the earring type cylinder, the oil is best entered and discharged from the highest point of the earring type cylinder. earring type cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

Piston earring type cylinder is widely used in hydraulic transmission. When the earring type cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the earring type cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the earring type cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

After chrome plating of the piston rod of the earring type 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.

earring type cylinder is the most important part of construction machinery, the traditional processing method is: broaching earring type cylinder block - fine boring earring type cylinder block - grinding earring type cylinder block. The rolling method is: broaching earring type cylinder block - fine boring earring type cylinder block - rolling earring type cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the earring type cylinder block is about 1-2 days, rolling 1 meter of the earring type 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 earring type cylinder increases by 25%. If the earring type 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 earring type cylinders, you must take the rolling production process. After the earring type 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.

Answers to some questions about earring type cylinder:

What are the main dimensions of the cylinder?
The main dimensions of the cylinder include: cylinder inner diameter, piston cylinder diameter, cylinder length, cylinder wall thickness, stroke, installation distance, etc.

To achieve the same stroke, which is better, hydraulic cylinder or lead screw?
If there is batch action, then the hydraulic pressure is better. Hydraulic: smooth operation, no lubrication, easy control, high control accuracy (can use proportional or servo system), the key is to manually control, but certainly to support the hydraulic system, for a single action must cost. Maintenance costs are also high. Lead screw: simple structure, easy to achieve, convenient maintenance, but must be lubricated, can not be manual, or manual control is inconvenient. See where it is used, if it is used in high-precision occasions, it must only be hydraulic, because the lead screw has a gap. There are many hydraulic actions, the hydraulic system itself must be prepared, then the use of hydraulic pressure is also very economical.
