Switzerland hydraulic cylinder,constant speed cylinder manufacturer,constant speed cylinder

(Switzerland constant speed cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to constant speed cylinder:

Factors that should be considered when selecting the oil seal in the constant speed cylinder: some specific factors should be taken into account when selecting the oil seal in the constant speed cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: constant speed cylinder diameter, piston rod diameter, piston rod and piston groove size, constant speed cylinder working pressure, constant speed cylinder movement speed, hydraulic system oil temperature and constant speed cylinder working environment.

When producing oil constant speed cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

The constant speed cylinder requires that the filtration accuracy of the system is not less than the 80um, and the oil pollution should be strictly controlled, the oil should be kept clean, the performance of the oil should be checked regularly, and the necessary fine filtration and replacement of new working oil should be carried out.

If the seal of the constant speed 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 constant speed cylinder, and the phenomenon of "pulling the constant speed 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.

Answers to some questions about constant speed cylinder:

Why are two cylinders not balanced with the balance valve?
Balancing valve is only suitable for occasions with low synchronous accuracy requirements, and proportional valves are recommended for occasions with high precision requirements.

What is a constant velocity cylinder? What is the difference between hydraulic cylinder and constant velocity cylinder?
The constant speed cylinder should be the same as the speed of the piston rod extension and withdrawal cylinder is called the constant speed cylinder. The difference between it and the ordinary hydraulic cylinder is that the ordinary hydraulic cylinder only has a piston rod extended out, and the general extension speed is slow and the recovery speed is fast, because of the relationship between the effective area. Effective area of piston chamber > Effective area of piston rod chamber. The effective area on both sides of the constant speed cylinder is the same, because there are piston rods sticking out at both ends. The application of constant speed cylinder is most common in grinding machines.
