supporting cylinder are widely used in Belgium，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed supporting cylinder for customers from Belgium.

Introduction to supporting cylinder:

The assembly work of the supporting cylinder has a great impact on the quality of the supporting cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.

The supporting cylinder is mainly composed of body, piston, piston rod, supporting cylinder head, supporting cylinder bottom, piston rod head and related auxiliary devices. The piston divides the supporting cylinder into two chambers, and moves reciprocally in the supporting cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the supporting cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the supporting cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the supporting cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the supporting cylinder bottom and the supporting cylinder head is serious, so the buffer deceleration should be set at both ends of the supporting cylinder The working medium of the supporting cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; supporting cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the supporting cylinder: The buffer structure of the supporting cylinder is to prevent the piston from colliding with the supporting cylinder head at the end of the stroke.

When the hydraulic oil is not pumped into the supporting cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the supporting cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

supporting cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the supporting cylinder head itself is the guide sleeve of the piston rod, the supporting cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the supporting cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

Answers to some questions about supporting cylinder:

What should we pay attention to when using the cylinder?
When using the cylinder, we should pay attention to the environment and temperature in which it is located as follows: 1. Before working, the hydraulic cylinder must carry out several reciprocating movements under low pressure (greater than the starting pressure), and work normally after removing the gas in the cylinder. 2. Precautions when removing the hydraulic cylinder: ① The pressure in the hydraulic circuit is reduced to zero before disassembly. ② The screw thread at the top of the piston rod should be prevented from damage when disassembling. ③ Due to the different structure and size of the hydraulic cylinder, the order of disassembly is also slightly different. Generally, the fastening bolt of the end cover should be loosened first. Internal card chain card key application special tools.

What is the difference between hollow and solid oil cylinders?
Hollow solid cylinder, according to conventional understanding, refers to whether the piston rod is solid or hollow. General ordinary hydraulic cylinder, the piston rod is solid structure. Hollow hydraulic cylinder refers to a hollow piston rod structure of the hydraulic cylinder, see the attached figure. Piston rod hollow function: 1, the piston rod hollow, the middle can be threaded rod. For example, the clamping cylinder with a sawing machine, the piston rod center threading rod, part of the stroke through manual, part of the stroke hydraulic automatic walk. 2, the hollow hole of the piston rod can be used to direct the oil circuit to achieve special oil circuit. 3, the cylinder is relatively large, the piston rod is relatively large, and the stroke is longer, in this case, the piston rod is hollow to reduce the movement friction and lateral force.
