A multistage centrifugal pump is a type of centrifugal pump that also relies on the rotation of the impeller to obtain centrifugal force and thus the material. When the gas density reaches the working range of the mechanical vacuum pump, it is extracted, thereby gradually obtaining a high vacuum. Our stainless steel Ring Mesh T-Shirt is crafted from 0.53mm wire, 3.81mm diameter mild stainless steel butted rings. These shirts provide a comfortable, authentic appearance. The stainless steel ring mesh T shirt was measured over gambeson and undergarments and also can be used as fashional or decorational shirts.

Qinghai Jiawei multi-stage centrifugal pump is a kind of centrifugal pump, which also relies on the rotation of the impeller to obtain centrifugal force and thus the material. When the gas density reaches the working range of the mechanical vacuum pump, it is extracted, thereby gradually obtaining a high vacuum.
An appropriate amount of water is contained in the multistage centrifugal pump body as a working fluid. When the impeller rotates clockwise, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring of approximately equal thickness depending on the shape of the pump chamber. The inner surface of the lower portion of the water ring is just tangent to the impeller hub, and the upper inner surface of the water ring is just in contact with the tip of the blade (actually the blade has a certain depth of insertion within the water ring). At this time, a crescent-shaped space is formed between the impeller hub and the water ring, and this space is divided by the impeller into a plurality of small cavities equal to the number of blades.
If the lower part of the impeller is 0°, the volume of the small cavity becomes smaller from 180° before the rotation, and it communicates with the suction port on the end face. At this time, the gas is sucked in, and when the inhalation is finished, the cavity is small. It is isolated from the suction port; when the impeller continues to rotate, the small cavity becomes larger and smaller, so that the gas is compressed; when the small cavity communicates with the exhaust port, the gas is discharged outside the pump.
In summary, the multi-stage centrifugal pump realizes inhalation, compression and exhaust by the change of the volume of the pump chamber, so it is a multi-stage centrifugal pump capable of variable volume.
Multi-stage centrifugal pumps can be used in many industrial sectors such as petroleum, chemical, machinery, mining, light industry, medicine and food. Multi-stage centrifugal pumps are widely used in many processes of industrial production, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum recirculation, and vacuum degassing. The flammable and explosive gas can be removed, and the dusty and water-containing gas can be removed. Therefore, the application of the water ring pump is increasing.
