Switzerland hydraulic cylinder,vehicle hydraulic cylinder manufacturer,vehicle hydraulic cylinder

(Switzerland vehicle hydraulic cylinder,produced by Hebei Hengyu company）

vehicle hydraulic cylinder are widely used in Switzerland，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed vehicle hydraulic cylinder for customers from Switzerland.

Introduction to vehicle hydraulic cylinder:

Do not enter foreign bodies when installing the vehicle hydraulic cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.

vehicle hydraulic cylinders in series, parallel and series parallel. Series: In the vehicle hydraulic cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the vehicle hydraulic cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the vehicle hydraulic cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the vehicle hydraulic cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.

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

Repair method of small range wear of oil vehicle hydraulic 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.

Answers to some questions about vehicle hydraulic cylinder:

There are four cylinders in the front top of the dump truck. When the second cylinder is lifted to half the height, it suddenly falls back more than 30 cm or so, and the cylinder continues to lift.
The problem is the cylinder, the second section of the different strength of the heart. When the oil supply resistance is small, the first out, when the power is not moving, the cylinder needs to be strong, because the second section needs to pop it out after a while when the pressure is large, the oil can not keep up, so it falls back, and the oil continues to keep up.

What is the material of the lift cylinder?
The cylinder is composed of many parts. The cylinder also contains the seal and the installation port at both ends, the material of these two parts is not easy to determine if there is no physical object. The cylinder body is generally 20 steel, 45 steel, 27SiMn and other materials, and the piston rod is generally 40Cr, 45 steel and other materials.
