(Poland yg series hydraulic cylinder,produced by Hebei Hengyu company）

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

Introduction to yg series hydraulic cylinder:

The yg series hydraulic cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.

The yg series hydraulic cylinder should be used correctly and maintained regularly. The yg series hydraulic cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the yg series hydraulic cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

When the yg series hydraulic 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.

The commonly used buffer structure of the yg series hydraulic cylinder is composed of a piston boss and a yg series hydraulic cylinder head groove. When the piston moves close to the yg series hydraulic cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

Answers to some questions about yg series hydraulic cylinder:

Why do two hydraulic cylinders lift out of sync?
There may be several situations (do not know the result of the equipment, may not be accurate) 1, whether the slow one is worn 2, whether there is air in the slow cylinder 3, if the two cylinders are supplied by the same oil port, whether the slow joint is blocked (some processing residue will reach a certain oil port under a certain coincidence condition, This situation will not happen if it is not necessarily good before) 4, the oil seal in the slow cylinder leaks, causing the feed oil to leak from the return oil end. Point 4 is most likely because it is invisible and a technical failure. If it is a dual oil feed (separate oil feed), it is also necessary to check the oil supply system and the oil return system (valve type).

What kind of seal ring we should choose for 120Mpa hydraulic cylinder?
The sealing rings used in mining machinery are high pressure, which can reach 150MPa. It is generally composed of three parts, the guide ring, the sealing body and the elastomer. It's not a special structure. It's more mature. Usually said mountain circle, bud circle.
