Petrochemical enterprises in the mechanical seal leakage

2010-08-03

With increasing levels of sealing technology, industrial pump seal is being used by the traditional packing seal development in the machine. Mechanical seal technology with its reliable performance, less leakage, long life, low power consumption, without regular maintenance, used in metallurgy, petroleum, chemical industry industrial pump. Through years of experience, summed up in the industrial pump mechanical seal repair and maintenance of some experience, we had some effect control leakage.

External causes of industrial pump mechanical seal failure

2010-07-28

Mechanical seal sealing surface have a certain specific pressure, so as to play a seal, which requires the mechanical seal spring to have a certain amount of compression to the seal faces a thrust, spin up the sealing surface to produce the desired ratio of seal pressure.

The reactor with mechanical seal installation and use

2010-07-12

Check the host that is associated with the installation of the mechanical seal parts size accuracy and geometric accuracy and mutual relationship meets the technical requirements.Basically has the following several aspects

Mechanical seal application in petrochemical industry

2010-07-05

Pump depends largely on the reliability of mechanical seals, in petrochemical enterprises, the process of fluid are flammable and explosive, once the mechanical seal leakage failure, not only pollute the environment, affect human body health, but also will lead to major accidents such as fire, explosion.We mainly from the oil refining pumps with mechanical seal sealing structure under different working condition selection of lower seal using failure rate, improve the use of reliability.

High-temperature, high-speed and other special conditions of the mechanical seal characteristics and maintenance methods

2010-07-01

Mechanical seal operating pressure exceeds 4 ~ 5MPa That belongs to the high-pressure seal range. Under high pressure conditions, due to excessive seal face value than the pressure, causing the end face of the heat, thereby undermining form a liquid film, resulting in abnormal wear. High pressure also make friction deformation and rupture. High pressure seal generally balanced structure, so face pressure in an appropriate range. But given the seal of reliability, balance coefficient increases can not be unlimited, so in some cases despite the use of balanced structure, but face pressure still may be larger. Balanced structure alone is difficult to meet the requirements, this situation can be more controlled membrane end mechanical seal or mechanical seal.
