Finland reciprocating cylinder

(Finland reciprocating cylinder,produced by Hengyu Group)

reciprocating cylinder are widely used in Finland,because of no transmission clearance,simple structure and reliable operation,excellent temperature resistance.So our company has designed reciprocating cylinder for customers from Finland.

Introduction to reciprocating cylinder:

The internal leakage of the reciprocating cylinder should be prevented when the reciprocating cylinder is used. The internal leakage of reciprocating cylinder includes the leakage caused by excessive wear of reciprocating cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.

Factors that should be considered when selecting the oil seal in the reciprocating cylinder: some specific factors should be taken into account when selecting the oil seal in the reciprocating cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: reciprocating cylinder diameter, piston rod diameter, piston rod and piston groove size, reciprocating cylinder working pressure, reciprocating cylinder movement speed, hydraulic system oil temperature and reciprocating cylinder working environment.

The piston seal of the reciprocating cylinder is the main element to prevent leakage in the reciprocating cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

The reciprocating cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the reciprocating cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The reciprocating cylinder is basically composed of reciprocating cylinder and reciprocating cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.

Answers to some questions about reciprocating cylinder:

Is a hydraulic cylinder and a jack the same thing?
Strictly speaking, no. Although the hydraulic principle is used, and even some of the longer jacks are similar to the cylinder, the internal structure of the two is different. There is a check valve inside the jack. After the top lift, the check valve locks the hydraulic oil circuit, and the hydraulic oil only enters and does not exit after the check valve locks, and can be lowered to complete a reciprocating movement. The cylinder is usually connected to the distribution tube to control the movement, and works with a wide variety of distribution valves and distribution systems according to different needs. The jack only needs a simple check valve.

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.
