(Cameroon land leveller hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

land leveller hydraulic cylinder are widely used in Cameroon，because of long service life，smooth movement，high work efficiency.So our company has designed land leveller hydraulic cylinder for customers from Cameroon.

Introduction to land leveller hydraulic cylinder:

In use, the land leveller hydraulic cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the land leveller hydraulic cylinder.

The land leveller hydraulic cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the land leveller hydraulic cylinder, bite. Elimination method: When installing the land leveller hydraulic cylinder, ensure that the axis position of the land leveller hydraulic cylinder is consistent with the direction of movement; Make the load borne by the land leveller hydraulic cylinder as far as possible through the land leveller hydraulic cylinder axis, to avoid the phenomenon of eccentricity.

If the seal of the land leveller hydraulic cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and land leveller hydraulic cylinder, and the phenomenon of "pulling the land leveller hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

When installing the land leveller hydraulic cylinder, the axial ends of the land leveller hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the land leveller hydraulic cylinder, there is axial expansion. If the two ends of the land leveller hydraulic cylinder are fixed, all parts of the land leveller hydraulic cylinder will be deformed. When disassembling the land leveller hydraulic cylinder, it is strictly forbidden to hammer the land leveller hydraulic cylinder and the piston surface, such as the land leveller hydraulic cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

Answers to some questions about land leveller hydraulic cylinder:

The pressure gauge of the hydraulic station reaches 20MPa. How many tons of weight can the hydraulic cylinder lift? How to convert?
20Mpa=200kg/cm^2 The weight of the cylinder with a cross-sectional area of 1 square centimeter can be lifted is 200kg, so F=200X3.14X (125/2) ^2 =24531kg =24.5 tons.

Are hydraulic cylinders divided into oil cylinders and water cylinders? What's the difference between the two types?
There are oil cylinders and water cylinders. The two cylinders are used in different environments. Oil cylinders are generally used in places where there is less demand for media, which is our most common hydraulic cylinders. Water cylinders are mainly used for large tonnage presses. Because the equipment is too large, the use of hydraulic oil will cause a relatively large waste. However, water is not pure water, there are oil-in-water emulsion and water-in-oil emulsion. Water has another benefit: it's flame retardant. It is especially suitable for some flammable and explosive occasions. Or with water glycol. The use of pure water is very little, mainly because the seal is not good and easy to rust.
