Brazil hydraulic cylinder,spring return cylinder manufacturer,spring return cylinder

(Brazil spring return cylinder,produced by Hengyu Group）

spring return cylinder are widely used in Brazil，because of clever hydraulic energy conversion，excellent temperature resistance，simple structure and reliable operation.So our company has designed spring return cylinder for customers from Brazil.

Introduction to spring return cylinder:

The spring return cylinder should be used correctly and maintained regularly. The spring return 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 spring return cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

The definition of the minimum stable speed refers to the minimum movement speed of the spring return cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the spring return cylinder that undertakes different work has different requirements for the minimum stable speed.

The body of the spring return cylinder on the processing process requirements: the body of the spring return cylinder is an important and essential part of the spring return cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the spring return cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

The "O" ring can be used as an auxiliary seal inside the spring return cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the spring return cylinder, and can be completely sealed.

Answers to some questions about spring return cylinder:

What is the material of the hydraulic cylinder slider?
Three parts of the hydraulic cylinder are essential, which are: cylinder - cylinder head assembly, piston - piston rod assembly, and sealing device. When you say slider, you mean piston. - Piston rod. Piston materials commonly used gray cast iron, wear-resistant cast iron, aluminum alloy (assembled), etc., can also be used 35 and 45 steel (integral). The piston rod is generally made of 35 and 45 steel. When the impact vibration is large, alloy steel such as 55 steel or 40Cr is used.

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).
