Sanyou Chemicals 400,000 tons of PVC project trial production
Sanyou Chemical disclosed that the 400,000-ton/year PVC and 500,000-ton/year caustic soda technical renovation project (Phase I) invested by Tangshan Sanyou Chlor-alkali Co. , Ltd., a subsidiary of the company, had recently been successfully tested and entered the pilot production stage. The technical and economic indicators of the project have reached the domestic advanced level. After the project is put into production, it is expected to realize a total profit of 54 million yuan. Sanyou Chemicals stated that the caustic soda produced by chlor-alkali can be used by chemical fiber companies to produce viscose staple fiber; the chlorine gas and hydrogen chloride produced are used for the silicon company's organic silicon monomer production; the waste calcium carbide sludge produced instead of lime milk is used for soda ash production. This reduces the consumption of limestone in the production of soda ash and reduces environmental pollution and costs. The new zero-electrode distance membrane electrolyzer and energy-saving fluidized bed equipment technologies used in the project are at the international and domestic advanced level, which can effectively reduce the energy consumption of the unit product, and has obvious energy saving and emission reduction effects.

2.Before installing the oil cylinder piston seal, the seal and sealing groove should be cleaned to ensure that the sealing surface is free of impurities.
3. When installing the seal, the correct installation sequence and direction should be carried out according to the drawing requirements to ensure the correct installation of the seal.
4.When installing the seal, special tools should be used to avoid using sharp tools and hard objects to damage the seal.
5. When installing the seal, attention should be paid to whether the seal groove is damaged or worn. If so, it should be replaced or repaired in a timely manner.
6. When installing the seal, an appropriate amount of lubricating oil should be applied to avoid friction damage to the seal during installation.
7.When installing the seal, it should be ensured that the compression of the sealing ring meets the requirements to avoid excessive or insufficient compression leading to seal failure.
8.After installing the seal, a sealing test should be conducted to ensure that the sealing performance meets the requirements.
