Background:

The selection of mechanical seals is a complex process that requires comprehensive consideration of multiple factors to ensure sealing performance and extend service life. The following is a selection guide compiled based on the provided search results.
1. Confirm the working parameters
The selection of mechanical seals must consider the following key working parameters: 1
Using pressure (p): The pressure of the medium at the sealed chamber can be used to preliminarily determine whether to choose a balanced structure and the degree of balance based on the magnitude of the pressure value.
Temperature (T): The temperature of the medium inside the sealed chamber is used to determine the material of the auxiliary sealing ring, the cooling method of the sealing surface, and its auxiliary system based on the temperature.
Working speed (v): The circumferential velocity of the average diameter of the sealing surface, which determines whether the elastic element rotates with the shaft based on the speed, i.e. using a rotating or stationary structure.
Sealing shaft diameter (d): The shaft diameter size during mechanical seal installation affects the structural type of the seal and the selection of the spring.
2. Consider the characteristics of the medium
The characteristics of the medium also have a significant impact on the selection of mechanical seals
Concentration and viscosity: affect the lubricity and pressure bearing capacity of the seal.
Corrosivity: determines the selection of sealing materials to resist chemical corrosion from the medium.
Solid particles and fiber impurities: affect the wear resistance and blockage risk of the seal.
Whether it is prone to vaporization or crystallization: affecting the structural design of the seal, such as using a large spring rotating structure to avoid blockage.
3. Working characteristics and environmental conditions of the host
The working characteristics and environmental conditions of the host are also factors that need to be considered when selecting
Continuous or intermittent operation: affects the design life and reliability requirements of the seal.
Installation location of the host: indoor or outdoor, affecting the protection level and environmental adaptability of the seal.
The nature of the surrounding atmosphere and temperature changes: affect the stability of the seal and the configuration of auxiliary systems.
4. Allowable leakage and lifespan requirements for sealing
The allowable leakage amount, leakage direction (internal or external leakage), lifespan, and reliability requirements of the host for sealing are also important criteria for selection.
5. Install effective space
The effective installation space of mechanical seals determines the installation type that should be adopted for mechanical seals, such as internal or external installation. At the same time, the installation of effective space also determines the spring properties of mechanical seals, such as multi spring, single spring, and wave spring.
6. Selection steps
The selection steps for mechanical seals are as follows: 1
1. Confirm the medium - select the material.
2. Confirm working parameters - select the sealing structure type and sealing auxiliary system.
3. Confirm the sealing usage conditions - check the sealing structure and material selection.
4. Confirm sealing dimensions - check the sealing and installation dimensions of the host.
5. Sealing selection - selection confirmation.
Through the above steps and precautions, the selection of mechanical seals can be effectively carried out to ensure that the selected mechanical seals can meet the usage conditions and have good economy.
