The seal support system is mainly used to improve the working conditions of mechanical seals and ensure the stable and reliable operation of mechanical seals.
1. Improve the working environment
Control temperature: Through cooling devices, such as cooling circulating water systems, the heat generated by friction during the operation of mechanical seals can be removed to prevent the seal surface from aging and deformation due to overheating, maintain sealing performance, and increase the service life of seals. For example, in a pump with high-temperature media, the cooling system can control the temperature of the sealing chamber within a reasonable range.
Filter impurities: Use the filter device to remove solid particles and impurities in the medium to prevent them from entering the mechanical seal surface, avoid wear and scratches on the seal surface, ensure the accuracy of the seal surface, and reduce the risk of leakage. For example, in a sewage pump that transports sand, the filter device can effectively protect the mechanical seal.
2. Optimize the sealperformance
Provide lubrication: Some seal support systems will inject lubricating fluid to form a lubricating film between the seal surfaces, reduce the friction coefficient, reduce wear, and at the same time improve the stability of the seal and reduce leakage. For example, in high-speed rotating machinery, good lubrication can reduce the friction between the seal surfaces.
Balanced pressure: The pressure balancing device can balance the pressure on both sides of the seal, reduce the damage to the seal caused by excessive pressure difference, improve the pressure resistance of the seal, and ensure that a good sealing effect can be maintained under different working conditions. For example, in a pipeline system with a high pressure difference, the pressure balancing device can protect the mechanical seal.
3. Extend the service life of mechanical seals:
Cooling, lubricating and flushing the seal chamber through seal support systems can effectively reduce the temperature of the seal surface, reduce wear and friction, and thus extend the service life of the mechanical seal. For example, the cooling system can prevent the seal surface from being deformed or damaged due to high temperature, and the lubrication system can reduce the friction coefficient and reduce the wear of the seal surface.
4. Adapt to complex working conditions: Under some special working conditions, such as high temperature, high pressure, high viscosity, medium containing particles, etc., the seal support system can help mechanical seals better adapt to these working conditions. For example, for medium containing particles, the use of appropriate flushing solutions can prevent particles from accumulating on the seal surface and ensure the normal operation of the seal.
5. Easy maintenance and monitoring: seal support systems are usually equipped with various monitoring and alarm devices, such as pressure sensors, temperature sensors, liquid level sensors, etc., which can monitor the operating status of the sealing system in real time. Once an abnormality occurs, an alarm can be issued in time, which makes it easier for maintenance personnel to find and deal with the problem in time, reducing maintenance costs and downtime.
Leakage monitoring: With the help of leakage monitoring devices, such as sensors installed near the sealing chamber, the leakage of mechanical seals can be monitored in real time. Once a leakage occurs, an alarm signal can be issued in time to remind the operator to take measures to avoid the expansion of the leakage accident.
Safety protection: When an abnormal situation occurs in the system, such as excessive pressure or temperature, the safety protection device in the seal support system will automatically start, such as opening the safety valve and actuating the emergency stop device, to protect the safety of equipment and personnel.
6. Environmental protection: seal support system can effectively control the leakage of media and reduce environmental pollution. Especially when dealing with toxic, harmful, flammable, explosive and other dangerous media, a good seal support system can prevent the media from leaking into the environment and ensure the safety of personnel and the environment.
7. Improve equipment operation efficiency: Due to the improved reliability of mechanical seals, the number of equipment shutdowns and repairs caused by seal failures is reduced, thereby improving the operation efficiency of the entire equipment and reducing production costs.
