(Indonesia pressure retaining cylinder,produced by Hengyu Group）

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

Introduction to pressure retaining cylinder:

The pressure retaining cylinder is not the same as the pressure retaining cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the pressure retaining cylinder can not be used as a high-power power component, but the pressure retaining cylinder can be used as a relatively large power component, or the pressure retaining cylinder system can be used.

The pressure retaining cylinder should be vented: when the pressure retaining cylinder is installed or parked for a long time to work again, the air will penetrate into the pressure retaining cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the pressure retaining cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the pressure retaining cylinder, the oil is best entered and discharged from the highest point of the pressure retaining cylinder. pressure retaining 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.

Repair method of small range wear of oil pressure retaining cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

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

What valve is used to control cylinder expansion?
Mainly use reversing valve, but the details of the control need hydraulic control valve, hydraulic control valve can be divided into direction control valve, pressure control valve, flow control valve. The valve controls the expansion of the cylinder is the direction control valve, that is, the reversing valve. What is the meaning of two-position three-way and three-position four-way of the reversing valve? Usually according to the different working positions that can stay after the spool is moved, it can be divided into: two-position valves, three-position valves and multi-position valves. According to the number of different slide valve channels can be divided into: two-way valve, three-way valve, four-way valve, five-way valve and multi-way valve. The name of the reversing valve is called the multi-position and multi-pass reversing valve according to its working position and the number of channels.

How to remove the lifting cylinder from the forklift truck?
The lifting cylinder is generally fixed on the door frame, and there are screws under and above it, and it is OK to loosen the screws with a wrench on the top. However, we must pay attention to ensure safety and prevent damage to the cylinder or safety accidents.
