S.Africa supporting cylinder

(S.Africa supporting cylinder,produced by Hengyu Hydraulic Co., Ltd)

supporting cylinder are widely used in S.Africa,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed supporting cylinder for customers from S.Africa.

Introduction to supporting cylinder:

supporting cylinder installation precautions: Before installing the supporting cylinder into the system, the parameters on the supporting cylinder label should be compared with the parameters when ordering. The base of the supporting cylinder must have sufficient stiffness, otherwise the supporting cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

The quality of the supporting cylinder can not be ignored in the purchase of the supporting cylinder. The supporting cylinder is the main component of the supporting cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. supporting cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of supporting cylinder is deep hole processing, which has always troubled the processing personnel.

The piston rod of the supporting cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

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

Answers to some questions about supporting cylinder:

Two cylinders in parallel, how to solve the synchronization problem?
The following methods can be used to achieve parallel cylinder synchronization: 1, rigid mechanical synchronization. 2. The throttle valve or speed regulating valve is used in the circuit to adjust the synchronization. 3, the two cylinders use independent quantitative pump oil supply to achieve synchronization. 4. Synchronous motor is used in the loop to realize cylinder synchronization. 5, using the position sensor to measure the stroke position and control the cylinder synchronization through the electrical system.

How big gear pump need to use for 60*100 cylinder?
One cylinder size alone does not determine the size of the pump used. Choose the size of the pump, at least to know 1, the size of the load is how much, by the size of the load and the size of the cylinder and other conditions can be calculated the pressure required by the hydraulic system. 2. Speed of operation. From this speed and cylinder size, the required flow rate of the system is calculated. The relevant parameters of the pump can be selected by the pressure and flow rate to determine what kind of pump is required.
