Application of Main Shaft Seal in Water Turbine
In recent years, our country's economy continues to develop steadily, and at the same time, the demand for power supply is increasing continuously, and now the main channel of power production is the hydropower plant, so the hydropower plant is now closely connected with the people's life. Water turbine is an important part of hydropower plants. And as for water turbine, the main shaft seal is its indispensable component. But the main shaft seal is easy to fail, and its safety cannot be guaranteed, so it is a problem to be solved urgently in the current domestic hydropower industry. At ...
Balanced and Non-balanced Seals of Mechanical Seal Ring
what is a balanced mechanical seal The balance of the mechanical seal ring has a great influence on the sealing pressure of the contact surface. This sealing pressure depends on the effective cross-section of the seal itself and the pressure in the packing box. The section on the opposite side of the rotating face of the non-equilibrium mechanical seal ring is fully exposed to the pressure range of the packing box. This situation will make high pressure between the sealing surface, which will make the working temperature increase, speed up the rate of wear. Under high temperature working conditions or ...
Basic Components and Functions of Mechanical Seals
Table of Content [Hide] 1. Dynamic and static rings 2. Elastic components (spring, corrugated plate, snake sleeve, etc.) 3. Auxiliary seal (0-ring, v-ring, wedge ring and other special-shaped seal ring) 4. Driving medium 5. Fastener Dynamic and static rings The sealing surface shall be tightly adhered to prevent medium leakage. It is required that the moving ring and the static ring have good wear resistance. The moving ring can move axially and automatically compensate for the wear on the sealing surface of the component mechanical seal to make it fit well with the static ring. The static ring has buoyancy and plays a buffering role. ...
Advantages of Carbon Mechanical Seal
The mechanical seal type multi spring can be used in a variety of elastomers and handle almost every kind of industrial liquid. All components are fixed together by snap ring with uniform structure design, which can be easily maintained on site. Its scope covers: carbon mechanical seal of industrial pump, mixer and agitator seal, cylinder seal, metal bellows seal, automatic cooling pump seal and air conditioning compressor lip seal. Carbon rings are widely used as sealing ring of carbon mechanical seal, because they have the following characteristics: Self-lubricating Corrosion resistance Thermal expansion Idling performance Good thermal conductivity Low friction coefficient ...
