spring return cylinder are widely used in Austria,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed spring return cylinder for customers from Austria.

Introduction to spring return cylinder:

The spring return cylinder pipe should not be left behind when deburring at both ends after the fixed length processing. In addition, the placement of steel pipes near the site of welding pipeline operations is the cause of welding foreign objects. The pipes placed near the welding operation site should be sealed. It must also be noted that pipe fitting materials should be fully prepared on a dust-free workbench.

When the spring return cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the spring return cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

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

The body of the spring return cylinder on the processing process requirements: the body of the spring return cylinder is an important and essential part of the spring return cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the spring return cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

Answers to some questions about spring return cylinder:

How to choose cylinder size, pump type, motor power for a 30-ton press?
30 tons = 30,000 kg. It is expected to use a 16 mpa oil pump, then the cylinder area =30000/(160x3.14) and then square, the cylinder bore is 150 mm. Calculated at 500 mm travel per minute, the flow rate per minute is :0.75^2x3.14x5=8.8 liters/minute. Motor power =8.8x16/60=2.355. A 9 L/min, 16 mpa pump is available. Piston diameter 150 mm cylinder. 3 kW motor.

How to remove the cylinder correctly?
(1) Before disassembling the hydraulic cylinder, the hydraulic circuit should be depressurized. Otherwise, when the tubing joint connected with the cylinder is loosened, the high-pressure oil in the circuit will be quickly ejected. The hydraulic circuit of the hydraulic press should first loosen the hand wheel or pressure regulator screw at the relief valve, so that the pressure oil is unloaded, and then block the power supply or block the power source to stop the operation of the hydraulic equipment. (2) When disassembling, it should prevent damage to the top thread of the piston rod, the oil thread, the appearance of the piston rod, the inner wall of the cylinder liner, etc. In order to prevent the piston rod and other slender parts from twisting or deformation, the use of cushion wood support balance when placed. (3) Disassemble in order.
