(Portugal servo cylinder,produced by Hebei Hengyu company）

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

Introduction to servo cylinder:

The scar on the sliding surface of the servo 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 servo cylinder wall. Therefore, before installation, these scars must be fully repaired.

The piston rod of the servo cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

When the servo cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the servo cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil servo cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical servo cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the servo cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

Under normal circumstances, the servo cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the servo cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the servo cylinder and the end cover, the piston and the piston rod, the piston and the servo cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the servo cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

Answers to some questions about servo cylinder:

How long can a hydraulic cylinder work continuously?
If the maintenance is good, the service life can be extended a lot. The life of the cylinder is related to the structure of the cylinder, working pressure, stress state, hydraulic oil cleanliness, oil temperature control, maintenance and preventive measures. For example, the cylinder structure, the inner wall of the cylinder has quilting, rolling, chrome plating and other methods, the sealing parts have polyurethane rings, glay rings, metal sealing rings, etc., different combinations, the life difference is dozens of times. Metallurgical system is a typical cylinder application, in 24 hours of work, a year or more can not be shut down, in the middle of continuous work.

The hydraulic cylinder is slow when moving forward and faster when moving back.
If the cylinder is single, it is slow when it is moving forward without the rod cavity, and fast when it is shrinking.
