The Structure Of Tandem Liquid Film Hydraulic Seal For Pump

The structure of tandem liquid film hydraulic seal for pump

What is a pump? A pump is actually a machine that transports or pressurizes a liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, making the liquid energy increase. The pump is mainly used to transport liquids such as water, oil, acid-base liquid, emulsion, suspension emulsion and liquid metal, and can also transport liquid, gas mixture and liquid containing suspended solids. Pumps can usually be divided into three categories: positive displacement pumps, dynamic pumps and other types of pumps according to their working principles.

Next, let's learn more about what is a liquid film rubber seal for a pump. There are three common structures:

Liquid film rubber single end face seal, liquid film rubber double end face seal, liquid film rubber series seal, gas film rubber series seal.

I. Features of tandem seal structure for rubber seal liquid film pump:

1. Structure: tandem, multi-spring.

   
   

2. The main and auxiliary seals are both liquid film seals.

3. The leakage of the sealed medium and buffer liquid can be realized, the power consumption is greatly reduced, and the service life of the seal in operation is also greatly improved;

4. Moreover, this seal also adopts the structure of inner diameter slotted end face seal, which has excellent ability to prevent solid particles.

5. What if the main seal fails? The seal at this moment will act as the primary seal for a short period of time, thus preventing a large leakage of the medium into the atmosphere

II. Characteristics of tandem sealing medium for rubber sealing liquid film pump (working environment, applicable occasions):

The rubber seal liquid film pump is used in series seal. This type of seal is more suitable for flammable, highly toxic and expensive process media.
