Q: What's the seal water? What about the water seal?: Seal water is to pump the water seal way, in operation the seal water pressure difference, mainly depends on the seal water to enter the water pipe's seal water control valve to carry on the automatic adjustment. The seal groove is arranged in the ash bucket of the lower box, the lower part of the length of a steel plate. Steel plate with displacement in the header, but still not out of the water, this is the one hand to ensure the water wall expansion free, and ensure good sealing process of expansion.

Q: Replacement seals, but it does not feel like a O ring, ask this solenoid valve seals what is the name, specifications how to express?: The form of the spool is globe, V-ball, hemisphere, butterfly valve plate and other types.The form of the valve must be selected according to the characteristics of various valves, the general will use the plunger valve.

Q: What are the seals commonly used in the industry?: In recent years, with the development of economy, the development of sealing industry is very fast. But unlike other industries, the development of the sealing industry is rapid, but the sealing enterprises are changing slowly. For example, at the end of 70s and early 80s, there are several manufacturers only in Jiangsu, Zhejiang and Shandong, and both coastal and inland, and the South and the north, everywhere seal factory, the entire industry has been sealed by the previous few, the development of 300, the growth rate can be said to be very fast. But in terms of individual enterprises, many enterprises did not change, the scale of production roundabout, or even reverse, the power of science and technology not only did not increase greatly, but some in the weakened, many manufacturers still hold "four old" do not put, that old products, old technology, old equipment, old size. Of course, there are some enterprises, imitation, imitation of some products stronger ability, but in the industry as a whole, independent development of new products capacity of enterprises is not much.In terms of products, the vast majority of manufacturers are still some winding gasket, packing ring, packing and high strength gaskets and other old products. Slightly new PTFE products, in technology and quality greatly behind foreign countries, such as PTFE packing, expansion PTFE tape. Looking around, new products are scarce.

Q: Why should the hydraulic cylinder be sealed? Which parts need to be sealed? What are the common sealing rings?: The main purpose of hydraulic cylinder is to push the piston through hydraulic oil to transfer energy to the force body. If the hydraulic cylinder is not sealed, then the oil leak, usually in the piston, both ends of the cylinder has a seal (including oil seals and dust laden).

Q: Design of sealing ring, groove and bottom fillet of sealing ring: The O ring seal is a typical extrusion seal. The compression ratio and stretch of the section diameter of O ring are the main contents of sealing design, which are important for sealing performance and service life. The O ring is usually installed in the sealing groove to seal. The good sealing effect of O shape seal ring depends largely on the proper matching of the size of the O ring and the groove size, forming a reasonable sealing ring, the amount of compression and the amount of tension. Sealing device design, processing, if the O ring compression is too small, it will cause leakage; too much compression will lead to O ring rubber stress relaxation caused by leakage. Similarly, excessive stretching in the work of the O ring will also accelerate aging and cause leakage. The standards of the countries all over the world have strict regulations.

Q: Reasons affecting the tightness of cylinder: 6 cylinder head flatness7, head of bolt preload8, cylinder head pad quality9 、 piston ring cylindricity and elasticity10 cylinder surface finish

Q: About the service life of hydraulic cylinder sealing ring: Haha, the inside of the injection molding machine or digging. Mechanical arm?.OK, OK on the market is a good one, is not ideal, relatively better, that is when others do use a standard material, without reducing scrap material cost.

Q: What are the common sealing forms of hydraulic cylinders?: Usually sealed rubber ring for sealing, and very few occasions, piston and cylinder will also be sealed with piston rings. There are many kinds of sealing rings, each of which has its own advantages. Some are simple, such as: O aprons. But the service life is short. Some are suitable for high voltage and high speed: so special.

Q: High speed up to 5000r/min, dusty and dusty workplace. Its seals are resistant to high temperatures.: The speed, temperature and pressure of the oil seals with different structures are different. If you have drawings, you can send them to me.

Q: Classification of the use of seals: 1. according to the function classification: divided into shaft seal, hole seal, dust seal, guide ring, fixed seal, rotary seal;2., according to material classification: divided into nitrile rubber, three yuan ethylene propylene rubber, fluorine rubber, silica gel, fluorine silicone rubber, nylon, polyurethane, engineering plastics, etc..
