HSBC Machinery has developed a completely leak-free sealed industrial pump

Since the domestic non-leakage sealing technology--mechanical seal applied to industrial pumps, many pump plants in China have used mechanical seals in the sealed part of the pump, but the effect is not satisfactory, especially in the coal washing industry, because the liquid solid particles are transported by the pump. Many, poor operating conditions, mechanical seals are sometimes not as reliable as packing seals, so China's medium pump seal technology has always been the world of packing seals, sealing effect is far behind and imported pumps.

China University of Mining and Technology takes the responsibility of revitalizing the national industry and takes the initiative to undertake the mission of developing a leak-free medium pump. Based on the international advanced sealing theory and years of practical teaching experience, the China University of Mining and Technology adopts a combined sealing technology with mechanical seal and auxiliary impeller seal. In 2002, it cooperated with Shandong HSBC Machinery Group Corporation to develop a “drip-free” slurry pump and circulating water pump. Filled the blank of domestic leakage-free sealing technology.

Nowadays, HSBC Group Corporation has developed a series of non-leakage slurry pumps and circulating water pumps based on this "non-leakage sealing technology" and is the only medium pump manufacturer to say goodbye to packing seals in China.

PVC Resin

PVC Resin is easy to process, and can be processed by molding, lamination, injection molding, extrusion, calendering, blow molding and other hollow methods. Polyvinyl chloride is mainly used to produce artificial leather, film, wire sheath and other plastic soft products, but also can produce plates, doors and windows, pipes and valves and other plastic hard products.

PVC Resin usually inculde carbide based and ethylene based. K66-K68 PVC RESIN, K59-K55 PVC RESIN, K71-K73 PVC RESIN. PVC RESIN SG5, PVC RESIN SG3, PVC RESIN SG8.

According to the different application scope, PVC can be divided into: general-purpose PVC resin, high polymerization degree PVC resin, and cross-linked PVC resin. General-purpose PVC resin is formed by the polymerization of vinyl chloride monomer under the action of initiator; high degree of polymerization PVC resin refers to the resin polymerized by adding chain extender to the vinyl chloride monomer polymerization system; cross-linked PVC resin is A resin polymerized by adding a crosslinking agent containing diene and polyene to the vinyl chloride monomer polymerization system.
According to the method of obtaining vinyl chloride monomer, it can be divided into Calcium Carbide method, ethylene method and imported (EDC, VCM) monomer method (the ethylene method and imported monomer method are commonly referred to as ethylene method).
According to the polymerization method, polyvinyl chloride can be divided into four categories: suspension polyvinyl chloride, emulsion polyvinyl chloride, bulk polyvinyl chloride, and solution polyvinyl chloride. Suspension process polyvinyl chloride is the largest variety in output, accounting for about 80% of the total output of PVC. Suspension method PVC is divided into six models according to absolute viscosity: XS-1, XS-2--XS-6; XJ-1, XJ-2--, XJ-6. The meaning of each letter in the model: X-suspension method; S-loose type; J-compact type.
