Croatia hydraulic cylinder,reciprocating cylinder manufacturer,reciprocating cylinder(Croatia reciprocating cylinder,produced by Hengyu Group)
reciprocating cylinder are widely used in Croatia,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed reciprocating cylinder for customers from Croatia.
If the seal of the reciprocating cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.
Under normal circumstances, the reciprocating 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 reciprocating cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the reciprocating cylinder and the end cover, the piston and the piston rod, the piston and the reciprocating 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 reciprocating cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.
When the reciprocating 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 reciprocating cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil reciprocating cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical reciprocating cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the reciprocating 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.
When installing the piston rod, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the reciprocating cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.
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.
When there is only one hole in the oil inlet and outlet of the hydraulic cylinder, will there be oil leakage?
It is a single acting oil cylinder. This oil cylinder is always driven by hydraulic oil in advance, and is generally pulled back by the spring at the bottom of the piston or the weight of the cylinder piston or the load. But either way, it has nothing to do with any internal leakage. Whether the oil is internally drained is related to the sealing and accuracy of the cylinder itself.
