The product variety, performance and appearance similarity of Chinese hydraulic cylinder manufacturing enterprises are strong. Backbone enterprises can almost produce a series of single-machine products used in the main process of multi-process forming process, but lack of specialized, refined, special products and complete sets of finished products. Before the delivery of hydraulic press products, due to the lack of process verification stage, often make the enterprise into the "products do not leave the factory rest assured, after delivery worry" awkward situation. The implementation of the brand strategy to accelerate the cultivation of leading industrial enterprises and industrial clusters, and strive for provincial and even national brand products and famous trademarks. Play the role of intermediary organizations to improve the industrial cluster environment. The process from enterprise cluster to industry cluster is the process from the increase of resource input to the integration of existing resource utilization ability. Establish intermediary self-regulatory agencies or trade associations related to industrial cluster activities. Through trade associations, we should unify norms and prices, oppose unfair competition, and constantly solve new situations and problems in our own development.

Hydraulic cylinder for hydraulic machinery is a very important component, in the whole hydraulic machinery plays a role of an executive component, the whole process of the hydraulic cylinder is the hydraulic energy into mechanical energy. With the development and progress of science and technology, as well as the wide application of hydraulic cylinder equipment, the innovation and development of hydraulic cylinder equipment is very rapid. Actively find and solve the problems in real life, set about research and innovation, so as to ensure the safety of production and the improvement of economic benefits while reducing costs and consumption. With the continuous development of China's hydraulic industry, the market supply and demand of domestic cylinder products have changed greatly in recent years, and the market supply and demand of China's cylinder industry has changed from a long-term "general shortage" to a "structural shortage". The emergence of the Chinese cylinder network, become the oil cylinder industry information flow set up a bridge, and in the future, it will bring a brilliant development of the oil cylinder enterprises.

The piston part of the hydraulic cylinder in the working state is to stick out of the cylinder, will naturally be oxide, acid gas erosion, which requires us to give it an appropriate amount of grease for protection, so as to avoid the piston as a load-bearing parts of the erosion and may occur in the work of broken. Second, to change the oil box. Because for a long time to use, it is inevitable that there will be foreign matter into the hydraulic cylinder, so in the use of friction will increase the phenomenon, in addition, the hydraulic oil is also a certain service life, long time do not change the oil will damage or erosion of the hydraulic cylinder inside. Prevention is better than cure, so in the work of the hydraulic cylinder to control the speed is appropriate, not more than 2m/s, which can extend the service life of the hydraulic cylinder, in addition to protect the mechanism and safety, internal installation of buffer device for the protection of the hydraulic cylinder is very effective.

The hydraulic cylinder is mainly used for supporting heavy objects for a long time. It can support the heavy objects while removing the oil pressure, and it is safe and reliable. Can be used underwater, single action, load retraction, nut self-locking to make the load more safe, especially in large projects, is easy to operate and control self-locking jack, design safety pressure device, built-in pressure relief valve to prevent overload, to protect self-locking jack for safe operation. The input of the hydraulic cylinder is the flow and pressure of the fluid, and the output is the linear motion speed and force. The piston of the hydraulic cylinder can complete the linear reciprocating movement, the linear displacement of the output is limited. Hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy of reciprocating linear motion. Hydraulic cylinder basically by cylinder cylinder and cylinder head, piston and piston rod, sealing device.
