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

Introduction to hydraulic engineering cylinder:

When the hydraulic engineering cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the hydraulic engineering cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

Disassembly hydraulic engineering cylinder: When disassembly hydraulic engineering cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the hydraulic engineering cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the hydraulic engineering cylinder.

The difference between the plunger hydraulic engineering cylinder and the piston hydraulic engineering cylinder is that the piston in the hydraulic engineering 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 hydraulic engineering cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

If it is found that the hydraulic engineering cylinder lubrication is poor or the hydraulic engineering cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the hydraulic engineering cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the hydraulic engineering cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the hydraulic engineering cylinder center line. In this way, when the piston works in the hydraulic engineering cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the hydraulic engineering cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

Answers to some questions about hydraulic engineering cylinder:

Is it good or bad for the hydraulic cylinder working in the limit stroke position?
It is not good for the hydraulic cylinder working in the limit stroke position. Generally, when the cylinder is used in the limit stroke, the oil in the cylinder will form a backflow back pressure impact on the piston and guide sleeve seals. If the limit is not accurate, it is easy to cause collision damage. It is recommended to leave a buffer of ten to twenty centimeters.

Does the abbreviation bc stand for bucket cylinder or boom cylinder?
Hydraulic excavator hydraulic cylinder includes boom cylinder, bucket rod cylinder and bucket cylinder three parts, four cylinders. Because of the different naming conventions of major manufacturers, the meaning of BC is also different, for the sake of insurance, you need to consult the manufacturer.
