(Japan stroke adjustable cylinder,produced by Hebei Hengyu company）

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

Introduction to stroke adjustable cylinder:

The difference between the integral stroke adjustable cylinder and the split stroke adjustable cylinder: The integral stroke adjustable cylinder and the split stroke adjustable cylinder in the stroke adjustable cylinder are two different stroke adjustable cylinders, and they are very different. The whole stroke adjustable cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split stroke adjustable cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and stroke adjustable cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

stroke adjustable cylinder hydraulic oil selection: The recommended working oil viscosity of the stroke adjustable cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

The difference between the plunger stroke adjustable cylinder and the piston stroke adjustable cylinder is that the piston in the stroke adjustable cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type stroke adjustable cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

When the stroke adjustable cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the stroke adjustable 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.

Answers to some questions about stroke adjustable cylinder:

What is the pressure provided for a 63-bore cylinder with a pressure of 2 mpa?
2 mpa pressure is equivalent to 20 kg per square centimeter, 6.3 cm straight longitude, 3.15 cm radius, square, multiplied by, calculated an area of about 31.5 square centimeters, multiplied by 20 kg, the pressure is about 630 kg.

What is a variable amplitude cylinder?
The type of variable amplitude cylinder is: double acting piston type cylinder, single acting plunger type cylinder, double acting two-stage telescopic cylinder. Double acting piston cylinder is the most common application. The oil cylinder has two oil outlets, and when the oil is fed into the A port, the oil is returned to the B port; If the oil inlet of the B port is returned to the oil of the A port, the reciprocating movement of the piston depends on the effect of pressure. Single-acting plunger (or piston) cylinder has only one oil port, the pressure oil can only supply oil to one side of the plunger in the cylinder, the plunger moves in one direction under the action of pressure oil, and the return stroke of the plunger is driven by the gravity of the lifting arm, such as the LT1040 truck crane variable amplitude cylinder. The double-acting two-stage telescopic cylinder is a set structure, and the two-stage piston rod is like a tie rod antenna set in the cylinder barrel.
