Kuwait hydraulic cylinder,forklift cylinder manufacturer,forklift cylinder

(Kuwait forklift cylinder,produced by Hengyu Hydraulic Co., Ltd）

forklift cylinder are widely used in Kuwait，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed forklift cylinder for customers from Kuwait.

Introduction to forklift cylinder:

If the seal of the forklift 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 forklift cylinder, and the phenomenon of "pulling the forklift 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.

forklift cylinder piston rod material selection and requirements: ① piston rod is usually made of 45 steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. The piston rod is generally designed as a forklift cylinder, if the diameter is larger, the hollow piston rod can be used. Made of No. 45 seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the working surface of the rod can be plated with hard chromium. ⑥ The piston rod and the end cap are guided by H8 ' forklift cylinder piston rod industry standard: piston rod diameter series of national recommended standard GB/T2348-1993. Piston rod thread size series standard GB/T2350-1980. Please refer to execute. There is no industry standard for piston rods Both the forklift cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The forklift cylinder mainly outputs linear motion and force. The forklift cylinder has a variety of forms, according to the different characteristics of its mechanism it can be divided into piston type, plunger type and swing type three categories, according to the mode of action he can be divided into single action and double action. Piston forklift cylinder, plunger forklift cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger forklift cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

The definition of the minimum starting pressure of the forklift cylinder refers to the minimum working pressure of the forklift cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the forklift cylinder parts and the size of the sealing friction.

forklift cylinder body inspection: The inner surface of the forklift cylinder and the piston seal are the main factors causing the leakage in the forklift cylinder, if the forklift cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the forklift cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

Answers to some questions about forklift cylinder:

Cylinder pressure calculation formula
The pressure of the cylinder at work is determined by the load, and the pressure of the physical force is equal to the force divided by the area of action (that is, P=F/S). If you want to calculate the output force of the cylinder, you can calculate it according to the formula: Set the radius of the piston (that is, the cylinder) is R (unit mm) the radius of the piston rod is r (unit mm) the working pressure P (unit MPa) the thrust of the cylinder F push =3.14*R*R*P (unit N) The pulling force of the cylinder F pull =3.14* (R*R-r* R) *P (unit N).

What are the four cylinders of the truck crane?
The four cylinders of the truck crane generally refer to the telescopic cylinder of the boom (to adjust the length of the boom), the variable amplitude cylinder of the boom (to adjust the elevation Angle of the boom), the horizontal telescopic cylinder of the support leg and the vertical cylinder of the support leg.
