Anonymous users2024-02-07Which manufacturers? There is no technical problem in the production of water ring vacuum pumps, it just depends on whether people are interested in producing.
The production of water ring vacuum pump technology is better: manufacturers in Shanghai, manufacturers in Boshan, Shandong, etc., depending on which series of water ring pump you are.

Anonymous users2024-02-06There are many factories that produce water ring pumps, depending on whether you want foreign or domestic. Foreign ones like Siemens and domestic Futong Vacuum are good manufacturers with high attainments in water ring pumps.

Anonymous users2024-02-05Water ring vacuum pump (referred to as water ring pump) is a rough vacuum pump, which can obtain an ultimate vacuum of 2000 4000pa, and a series atmospheric ejector can reach 270 670pa. The water ring pump can also be used as a compressor, called the water ring compressor, which is a low-pressure compressor, and its pressure range is 1 2 105pa gauge pressure.

Anonymous users2024-02-03The function of the water ring vacuum pump is to use the negative pressure conditions formed by itself to extract non-condensable, insoluble in water and non-particulate gases under the condition that the previous level of equipment is forming and operating normally.
Water ring vacuum pumps are used in various fields such as: chemical, pharmaceutical, papermaking, mining, food, etc., mostly used for purification, drying, etc.

Anonymous users2024-02-01Wrong selection leads to excessive exhaust volume, and the electric DU machine runs under excessive load;
The inlet gas contains corrosive DAO gas, which causes the impeller to be corroded, and even the impeller is fragmented and scrapped;
The installation of the pipeline is unreasonable, resulting in problems in water level control and failing to meet the nominal indicators;
The water temperature is too high, resulting in the ultimate vacuum not reaching the nominal value.
And some of them, I can't remember them for a while.

Anonymous users2024-01-31The structure is simple, the manufacturing accuracy is not high, and it is easy to process.
The structure is compact, the number of revolutions of the pump is high, and it can generally be directly connected with the motor without a deceleration device. Therefore, with a small structural size, a large exhaust volume can be obtained, and the floor space is also small.
Compressed gases are basically isothermal, i.e., the temperature of the compressed gas process changes very little.
Since there are no metal friction surfaces in the pump chamber, there is no need to lubricate the pump and there is very little wear. The sealing between the rotating and fastening parts can be done directly by the water seal.
The suction is uniform, the work is stable and reliable, the operation is simple, and the maintenance is convenient.
Water ring vacuum pump disadvantages:
The efficiency is low, generally around 30%, and the better one can reach 50%.
The vacuum level is low, not only because of the structural limitations, but more importantly by the saturation vapor pressure of the working liquid. With water as the working fluid, the ultimate pressure can only reach 2000 4000pa. Oil is used as the working fluid, up to 130pa.
In short, because the gas compression in the water ring pump is isothermal, flammable and explosive gases can be pumped out. Since there is no exhaust valve and friction surface, dusty gases, condensable gases, and gas-water mixtures can be extracted. With these outstanding features, it is still widely used despite its low efficiency.
Water ring vacuum pump features:
Compact structure, reliable working balance and uniform flow, so it is mostly used to transport or pump flammable, explosive and corrosive gases in chemical production. The efficiency of the water ring vacuum pump is very low due to the large energy loss due to the impeller agitating the liquid.

I studied accounting, and the candidate for literature is a good accountant. I used to study science, and I felt a little bored studying accounting, but my classmates in liberal arts liked it. Those who study accounting can do auditing and finance, and the prospects are good.
When was the primordial earth born? According to the widely circulated scientific opinion, the primordial Earth was born about 50 million years after the formation of the solar system. But a new view put forward by Jacobson, a scholar at Harvard University in the United States, is that the primitive earth was formed much earlier than that. >>>More
The formation of foam is very simple, as long as a gas is introduced into the solution of foaming agents (surfactants or polymer compounds), foam is formed on the surface of the solution. After the foam is formed, the liquid entrained between the walls of the bubbles is lost downward under the action of gravity, the liquid film gradually becomes thinner, and the bubbles are close to each other and deformed. Figure 1 shows the deformation of three bubbles as they approach each other, and the junction of the three bubbles is called the Prato junction. >>>More
