land leveller hydraulic cylinder are widely used in Uzbekistan，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed land leveller hydraulic cylinder for customers from Uzbekistan.

Introduction to land leveller hydraulic cylinder:

How to determine the working pressure of the land leveller hydraulic cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, land leveller hydraulic cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.

The scar on the sliding surface of the land leveller hydraulic cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the land leveller hydraulic cylinder wall. Therefore, before installation, these scars must be fully repaired.

The method of sleeve land leveller hydraulic cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the land leveller hydraulic cylinder can be significantly improved by rolling in the finishing of the inner holes of the land leveller hydraulic cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

Because of the slightly complex structure of the buffer land leveller hydraulic cylinder, sometimes there will be problems, such as when the land leveller hydraulic cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

Answers to some questions about land leveller hydraulic cylinder:

How to calculate the hydraulic cylinder pressure? How much pressure can put up how much weight?
If you want to calculate the pressure of the cylinder, you must know the inner diameter of the cylinder, if the piston rod is needed to lift the weight, it should be: cylinder (no piston rod end) pressure = load (4000N) ÷{(PI /4)X the square of the cylinder diameter (mm) ", it has nothing to do with the piston rod diameter, the rod diameter of the piston rod is only related to the stability of the cylinder. The pressure inside the cylinder should be p=F/S=400×10/(3.14×(0.5×25)×(0.5×25))=8.15MPa which means that you need to provide at least that much pressure to complete the operation.

How to calculate the hydraulic cylinder pressure, how much pressure can put up how much weight?
There is a formula for air pressure, hydraulic pressure, water pressure: F=P×S type: f-cylinder or hydraulic cylinder output, unit is Newton (N) P- pressure, unit is Mpa S- effective area, unit is square millimeter (mm2), note: is the effective area, in the hydraulic cylinder to subtract the cross-sectional area of the piston rod.
