increase Mechanical seal manufacturer Effective measures for installation quality
The quality of mechanical seal is related to the normal operation of equipment. Improving the quality of mechanical seal is conducive to reducing seal failure, improving the efficiency of mechanical equipment and increasing the service life of mechanical equipment. The effective measures to improve the installation quality of mechanical seals are as follows:
1. Avoid chemical corrosion of seals
In combination with the flushing transport medium, it is necessary to select materials with strong mechanical sealing. Adjust and control the elastic value of bellows according to the sealing status. For sealing elements with corrosive media, the corrosion resistance of the seal itself should be analyzed in the application process, and the application performance of various materials should also be analyzed. In the process of selecting auxiliary seal ring materials, in addition to judging the basic elastic requirements, the corrosion resistance and heat resistance of the medium should also be analyzed.

2. Prevent mechanical failure
The solid particles entering the sealing surface are mainly caused by the leakage of the medium. When the flushing fluid is mainly from the outlet, the best flushing scheme can be selected to enable the solid particles to be separated from each other. The seals should be fully flushed with the flushing fluid with high cleanliness. If it is not possible to use high cleanliness flushing fluid for flushing, the application of friction pair materials can be optimized. In view of the seal failure caused by the vibration of the pump body, the production technology process and various operations should be controlled to prevent cavitation problems. The clearance between the pump cavity impeller and the mouth ring is analyzed. The relevant technicians shall adjust and control the bearing failure, re arrange the pipes, and measure the size of key points during the installation of the equipment.
3. Optimize adjustment and installation operation
Before the installation of mechanical seal components, it is necessary to analyze the requirements of component models, basic specifications, etc. to ensure that they can meet the requirements of design drawings. Control the deflection and swing of the driving shaft to ensure that it can meet the standardized technical requirements. During installation and operation, relevant personnel need to analyze the requirements of the seal installation manual and standardized operation requirements, clean the installation environment, and ensure that the sealing surface is free of any impurities. The seal itself has a certain permeability. In order to control the permeability, immersion treatment is required after machining. If the leakage problem occurs from the seal, it means that the seal has been broken. Control the operating conditions of each inspection to avoid seal failure caused by overload and unreasonable installation operation.
4. Control sealing high temperature
If the medium in the pump is high temperature liquid, it is necessary to appropriately expand the clearance of the throttling bushing to ensure that the clearance can maintain the optimal clearance value, appropriately expand the flushing volume, and increase the pressure of the seal chamber through flushing to avoid the gasification problem of the medium. Expanding the application of heat exchanger and reducing the temperature value of flushing fluid can effectively reduce the large amount of heat generated by friction, and exhaust before starting the pump. For the pump with dirty medium, the application of the pump outlet filter should be checked regularly, and the high-temperature resistant materials should be replaced in time.
