flange type cylinder are widely used in Britain，because of excellent fatigue and impact resistance，long service life，simple structure and reliable operation.So our company has designed flange type cylinder for customers from Britain.

Introduction to flange type cylinder:

The flange type cylinder is mainly composed of body, piston, piston rod, flange type cylinder head, flange type cylinder bottom, piston rod head and related auxiliary devices. The piston divides the flange type cylinder into two chambers, and moves reciprocally in the flange type 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 flange type cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the flange type 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 flange type 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 flange type cylinder bottom and the flange type cylinder head is serious, so the buffer deceleration should be set at both ends of the flange type cylinder The working medium of the flange type cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; flange type 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 flange type cylinder: The buffer structure of the flange type cylinder is to prevent the piston from colliding with the flange type cylinder head at the end of the stroke.

When the piston speed of the flange type cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the flange type cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

Repair method of small range wear of oil flange type 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.

When the flange type cylinder is customized, if there are high requirements for the quality of the flange type cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the flange type cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the flange type cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

Answers to some questions about flange type cylinder:

How do hydraulic equipment and hydraulic cylinders maintain a certain pressure after pressing to a certain position?
There are several methods. 1. You can use a constant pressure variable pump to adjust the control pressure of the pump to the pressure required by the cylinder, so that when the cylinder is in place, the pump uses the minimum flow rate to maintain the pressure, and the system is more energy saving. 2. If the pressure is maintained for a short time, a hydraulic control check valve can be added to the oil inlet end of the cylinder to close the cylinder and maintain the pressure. If the volume of the cylinder is large, an accumulator can be added between the valve and the cylinder to maintain pressure for 10-30 minutes. 3. You can add a small flow pump, the large pump after unloading, the small pump has been running, specifically for maintaining pressure.

How does the one-way solenoid valve control the hydraulic cylinder circuit?
If your cylinder is single-acting, you can use a one-way solenoid valve, such as some lifting platform hydraulic cylinder, the support valve used is one-way (two-position tee), that is, the cylinder extends out by the oil pressure top, the cylinder retracted by its own weight.
