Italy hydraulic cylinder,spring return cylinder manufacturer,spring return cylinder

(Italy spring return cylinder,produced by Hebei Hengyu company）

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

Introduction to spring return cylinder:

When the spring return cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the spring return cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

The cavitation of the spring return cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the spring return cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.

The scar on the sliding surface of the spring return cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the spring return cylinder wall. Therefore, before installation, these scars must be fully repaired.

When the spring return cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.

Answers to some questions about spring return cylinder:

In hydraulic equipment, is the motor power related to the cylinder pressure holding time?
Irrelevant. The motor only drives the plunger in the hydraulic cylinder of the oil pump to extend out, and stops when the set pressure is reached; The length of the pressure holding time is related to the sealing degree of the hydraulic cylinder and the solenoid valve.

The inner diameter of the injection cylinder is 203.2mm and the diameter of the screw is 63.5mm. What is the enhancement ratio?
Oil pressure multiplied by the cross-sectional area of the cylinder is equal to the theoretical output force value, and then multiplied by the efficiency of the cylinder is equal to the actual output force value, and the oil pressure can be calculated by inverting the value input.
