(Czech Republic synchronous hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to synchronous hydraulic cylinder:

synchronous hydraulic cylinder buffer valve inspection and maintenance: For the valve buffer synchronous hydraulic cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

If the seal of the synchronous 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 synchronous hydraulic cylinder, and the phenomenon of "pulling the synchronous 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.

synchronous hydraulic 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 synchronous hydraulic 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 ' synchronous hydraulic 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 synchronous hydraulic cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The synchronous hydraulic cylinder mainly outputs linear motion and force. The synchronous hydraulic 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 synchronous hydraulic cylinder, plunger synchronous hydraulic cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger synchronous hydraulic cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

When the synchronous hydraulic cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the synchronous hydraulic cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.

Answers to some questions about synchronous hydraulic cylinder:

The cylinder is moving too fast. I want to slow it down. What can I do?
The hydraulic cylinder is the execution action, and the power source is the hydraulic system. The cylinder speed is too fast, indicating that the system flow is large, the hydraulic system has a hydraulic valve responsible for speed control function, method: 1, by adjusting the speed control valve to reduce the speed; 2, the speed control valve has been adjusted to the lowest, indicating that the hydraulic system design flow is too high, the need to re-configure the hydraulic system according to demand, or the cylinder diameter is changed.

Design a hydraulic cylinder, the inner diameter of the cylinder is 100mm, what size of piston rod is best used?
This involves how much speed ratio you need, that is, the area ratio of the rod cavity and the rodless cavity, if the weight is relatively large, it is recommended that the speed ratio choose 2, that is, the piston rod diameter choose 70mm, under normal circumstances, the speed ratio choose 1.46, the piston rod diameter choose 55mm. Of course, there are many factors that affect the diameter of the piston rod, such as stroke, stroke is too long, in order to stabilize the work of the hydraulic cylinder, its diameter also needs to choose a relatively large, sometimes even non-standard products, need to choose according to the actual situation.
