Vacuum pump liquid ring principle and interest
Apparatus according to claim 1, wherein said cone is provided with at least one radial notch at the small end of the cone for directing water from the interior of the cone over the small end of the cone to the seal segment of the cone. The shaft power is mainly composed of two parts: Correspondence should be addressed to Si Huang ; nc.
When each chamber rotates to the discharge port opening, the compressed air or gas escapes from that chamber through the discharge port to the internal discharge passage. This diagram demonstrates what the rotor and body do while the pump is in operation. This allows control of the cone to rotor clearance to be made over the vacuum pump liquid ring principle and interest area of the cone where this radial clearance is needed to keep the high pressure discharge gas from recirculating past the land area into the inlet segment.
Thus, the actual operating cycle is composed of four processes: Liquid-ring compressors are often used in vapor recovery systems. The design and operating parameters of the liquid ring vacuum pumps are listed in Table 2.
The invention provides a cone with close radial clearance to the rotor blades primarily in the land area and the small diameter end of the cone.

Another application is the vacuum forming of molded paper-pulp products egg cartons vacuum pump liquid ring principle and interest other packaging. Alternatively, the land segment 50 of the cone which is subject to wear by the close radial clearance to the rotor blades, can be a replaceable wear plate 80 of hard material see FIG.
International Journal of Rotating Machinery. Liquid usually water is fed into the pump and, by centrifugal acceleration, forms a moving cylindrical ring against the inside of the casing. An internal passage joins the openings from the pump inlet to an inlet port in the cone.
They are used to maintain condenser vacuum on large steam-turbine generator sets by removing incondensable gasses, where vacuum levels are typically 30—50 mbar. About News Investors Careers. Retrieved from " https: Thus, the actual operating cycle is composed of four processes: A multiparameter data acquisition and processing system were used in the performance tests and the detailed measurement method was introduced in [ 21 ].
As announced, we presented several sizes and versions of our new series of Dolphin View at Google Scholar K. The ability to use any liquid allows the liquid-ring vacuum pump to be ideally suited for solvent vapor recovery. The effective power of the liquid ring pump is generally calculated according to the isothermal compression power. An alternative embodiment includes a replaceable wear plate in the seal segment.
If a process, such as distillation or a vacuum dryer, is generating toluene vapors, for example, then it is possible to use toluene as vacuum pump liquid ring principle and interest sealant, provided the cooling water is cold enough to keep the vapor pressure of the sealant liquid low enough to pull the desired vacuum. This diagram demonstrates what the rotor and body do while the pump is in operation. The earliest liquid-ring pumps date fromwhen a patent was granted in Germany to Siemens-Schuckert. Typically a multistage pump will have up to two compression stages on a common shaft.
