Floating impeller axial force self-balancing device
The balancing disc device has two gaps, the radial gap behind the impeller and the axial gap of the balancing disc, because of these two gaps, the balancing disc can automatically adjust the axial l gap to achieve automatic axial force balancing, and the silver rotor is in a floating state.
The principle of the balance plate is transplanted to the impeller, the impeller back mouth ring radial clearance below the axial clearance, this device that is the same as the balance plate, the formation of two gaps, only in a different position. Because the impeller has these two gaps to complement each other, so that the impeller can also achieve automatic axial force balance.

Assuming that the axial force pointing to the impeller inlet increases, the impeller moves to the left, then the axial gap b2 decreases, the leakage decreases, the pressure in the cavity of the back mouth ring decreases, the impeller moves to the right, and so on, the impeller has been in a floating state for left and right adjustment (the balancing disk device makes the whole rotor in a balanced state). The axial clearance below the balance hole or external return pipe to the inlet, so that the pressure in the cavity N is the same as the inlet pressure.

Many people have wanted to buy stainless steel gate valve such things to help the engineering process, to facilitate the work, but the advantages and disadvantages of stainless steel gate valve such things are not enough to understand, do not know what characteristics it has, what need to pay attention to. So now here is to introduce to you what the advantages and disadvantages of stainless steel gate valves are, so that you can weigh the degree of applicability of this equipment to yourself.
Stainless steel gate valves
The advantages of this equipment are: firstly, it is very convenient to switch on and off, very labor-saving, so it can be carried out very easily; secondly, it is not subject to movement when the fluid flows; thirdly, it is not easy for the sealing side of the equipment to be scoured and eroded, so it is not easy to lead to depreciation; fourthly, the construction of the equipment is simple in shape, so the length of the structure is short, and there is a very good production process, so the scope of application is very wide;.

These are the advantages of this equipment. Of course, in addition to the advantages there are also disadvantages.
Firstly, although the medium does not cause erosion and wear to the sealing surfaces, they do rub against each other and are difficult to repair once there are frictional scratches etc., so this is a disadvantage.
Secondly, although the length of the machine is short, the size of the shape is large, so when opening it is necessary to find a place with a lot of space, and also therefore, the process of switching is longer; thirdly, it is the structure of the machine is more complicated, so for many people who are unfamiliar with the machine, it looks like a problem.
So these are the advantages and disadvantages of stainless steel gate valves, all analysed in great detail for you. If you do not know this equipment before, do not understand its advantages and disadvantages of each what, refer to the above we analyse for you, I believe that will certainly make your understanding of this equipment increased, but also conducive to weighing this equipment is suitable for you.
