Through nearly 50 years of development, the hydraulic industry has possessed the strength and technical level suitable for production, which can basically meet the needs of economic development. The supporting rate of complete sets of equipment has reached more than 60%, especially the rapid growth of the bottom occupation in the past 10 years , Actively promote the development of the hydraulic industry. As one of the most sophisticated products of hydraulic products, oil cylinders have formed a relatively sophisticated supply and demand chain and have a large market space.

Current Internet survey

According to the current Internet survey report, the sales revenue of domestic hydraulic cylinder production increased from 3.1 billion in 2015 to 11 billion in 2010, an increase rate of 28.9%.

However, like the hydraulic industry, the ratio of cylinders to the country’s total industrial output is still Relatively low, far below the level of developed countries abroad. Compared with China’s relatively large market demand, relatively low cost and other advantages, it is estimated that the future will become the center of gravity of the international hydraulic industry and cylinder industry.The screw jack manufacturers in china provides a maintenance method.

The work of cylinders

The work of hydraulic cylinders is basically the same. There are five basic components: exhaust equipment, buffer equipment, sealing equipment, piston rod and piston, cylinder head and cylinder tube. After more than 10 years of industry research, the precision jack has found that the working principle of each cylinder is almost similar. It is illustrated by a manual jack: the jack is a relatively simple cylinder.

Avoid accidents and damage

When there is a load, do not remove the quick connector to avoid accidents and damage to the parts.If oil is used as the medium, the maintenance of the oil and the equipment must be done well to avoid blockage or oil leakage, which will affect the use effect.For new or long-placed hydraulic jacks, because there is more air in the cylinder, the piston rod may suddenly jump slightly when you start using it.The screw jack manufacturers in china pays attention to the rationality of the design.


If there is blasting, bulging, leakage, etc., it cannot be used.The jack is a spring reset structure, which can be quickly taken out after lifting, but the jack cannot be pulled by the connected hose.Because the lifting stroke of the jack is small, the user must not exceed the rated stroke when using it to avoid damage to the jack.Avoid violent jack vibration during use.Not suitable for use in workplaces with acid, alkali and corrosive gases.The user should check and maintain regularly according to the usageStrictly abide by the technical specifications during operation, and users should check and maintain them regularly according to the usage conditions.
