What Are The Water And Cooling Water In The Mechanical Seal?

What are the water and cooling water in the mechanical seal?


Mechanical seal water and mechanical seal cooling water problems:

1 Overview:

Mechanical seal: It is a sealed form of rotating machinery such as water pump;

Sealing points of the pump: packing seal, mechanical seal, floating ring seal, etc.

Mechanical seal is based on two tight maintenance of mechanical seal pressed together dynamic and static ring sealing work, the application of tight force Sulzer pump supporting mechanical seal is by compression spring;

If the dynamic and static ring seal surface is damaged, the mechanical seal leaks.

When the mechanical seal is working, there is no dry friction between the two sealing surfaces of the moving and stationary ring. There must be lubricating fluid. This is the mechanical seal water, which comes from the water inside the pump body itself;

The mechanical seal cooling water, it is the water source for the mechanical seal water, it is used to cool the sealing water;

It comes from a closed water source, is to order a mechanical seal in order to prevent mechanical seal water temperature is too high, have an impact on the service life of the mechanical seal. The principle of their work is this.

2, mechanical seal water does not necessarily come from the pump's internal, if the pump working medium temperature is high, there is corrosion or particles, it will cause damage to the mechanical seal, under these circumstances, the general use of external clean water as mechanical seal water introduced into the sealed chamber;

3, mechanical seal cooling water generally does not flow through the sealing surface but through the seal gland to take away the heat generated in the mechanical seal work, with open water (industrial water), etc., on the water quality requirements are not high;

4, according to the use of the occasion above the two are not necessarily all set, such as the amount of mechanical seal water can meet the cooling requirements do not have separate cooling water.
