Classification of seals and the role of different seals

   Buffer ring, high pressure retaining seal ring on construction machinery; special seals on high-altitude and safety operation machinery; high temperature seals on high temperature machinery and cold seals on low temperature machinery; high pressure oil seals on high pressure rotating machines, etc., which are not included in this catalog.

About general machinery: the general machinery referred to here is the hydraulic pressure, speed, temperature level and other occasions used in general pressure, speed, temperature level

Machinery and equipment, it is no very special requirements for the safety of the system, work tasks and operating characteristics, so the use of sealing products will not put forward excessive performance requirements, such as ordinary hydraulic presses, ordinary machine tools, forklifts, plastic machines and light industrial machinery.

   Off-duty professional machinery: the professional machinery referred to here is in the special pressure, speed, temperature level and special occasions in the application of

   Professional hydraulic machinery and equipment, it has certain special requirements for the safety of the system, work tasks, operating characteristics, environmental conditions, etc., so that it can effectively complete the specified special work tasks, so this type of machinery on the use of sealing products have some special performance requirements (such as special reliability, pressure resistance, speed performance, temperature performance, durability and safety, etc.), this type of machinery such as Aerial work machinery, cranes, coal mining machinery, steel machinery, port machinery and some maintenance equipment.

On the maintenance products: is in use for mechanical equipment when the hydraulic system failure, the urgent need to replace the hydraulic seal

or when the hydraulic equipment needs to carry out the system transformation, re-selection of the appropriate application of seals. The supply characteristics of these products require promptness, accuracy, efficiency and reliability.

About supporting products: In the factory processing and production of hydraulic systems and hydraulic cylinders, the need to choose the technology, performance, quality, standards, cost, delivery cycle of the selected products to demonstrate the choice, so that hydraulic equipment can meet the advantages of advanced technology, reliable performance, reasonable cost, timely delivery, convenient after-sales service. This is a very strict system engineering, over the years our company has been cooperating with industrial enterprises to complete one after another sealing system supporting business.

About the machine repair kit: When repairing a component or unit of the hydraulic system of machinery and equipment, the seal combination parts need to be replaced, so that the mechanical system after the seal replacement and maintenance of its performance indicators back to normal, this kind of group supply of seal combination parts is called the machine repair kit. The seals in the machine repair kit must fully meet the technical and performance requirements of the original parts, in order to make the repaired machine cry into normal use
