(Australia folding machine cylinder,produced by Hengyu Group）

folding machine cylinder are widely used in Australia，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed folding machine cylinder for customers from Australia.

Introduction to folding machine cylinder:

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

When the initial action of the folding machine cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the folding machine cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

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

The pressure of the sliding surface of the folding machine cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the folding machine cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.

Answers to some questions about folding machine cylinder:

What is a hydraulic cylinder assembly?
Assembly, which means aggregate. A series of parts or products, formed to achieve a specific function of the whole, the general term for this system is assembly. The hydraulic cylinder assembly is not a single hydraulic cylinder part, which can be used by connecting the hydraulic hose.

Why is there noise in the hydraulic cylinder of the excavator lift arm?
There is no noise of a normal cylinder, check whether the throttle is ringing, or the mechanical part connected with it is ringing, and the mechanical part can be greased. If it can't be ruled out, disconnect the cylinder from the mechanical part and act alone to see what the situation is.
