Abstract
The utility model relates to a liquid ring type vacuum pump set which comprises a two-level water ring pump (1), a gas-liquid separator (2), a cooling device (3), a gas intake valve (4), an overflow valve (5) and a water intake valve (6). The two-level water ring pump (1), the gas-liquid separator (2) and the cooling device (3) are sequentially communicated through a pipeline in a circulating mode. The liquid ring type vacuum pump set has the advantages of being high in vacuum degree, strong in adaptability, capable of pumping out almost all of industrial gases when a proper work medium is selected, stable in operation process of the vacuum pump and low in noise.
Description
Technical field
The utility model relates to a kind of vacuum generating equipment, particularly a kind of liquid-ring vacuum pump unit.
Background technique
Oil-sealed rotary pump commonly used, when pressurized gas, temperature variation is very big, and air-breathing inhomogeneous, affects vacuumizing effect.Nash hytor can overcome the shortcoming of above-mentioned oil-sealed rotary pump as a kind of coarse vacuum pump, and that it is that variation by pump chamber realizes is air-breathing, compression and exhaust, so it belongs to the variable-capacity vacuum pump.The process of water ring pump pressurized gas is isothermal, so can extract inflammable, explosive gas, can extract dust-laden in addition, moisture gas, therefore, the application of water ring pump increases day by day, water ring pump is used self-priming water pump at first, after be used for gradually the industrial departments such as oil, chemical industry, machinery, mine, light industry, papermaking, power, metallurgy, medicine and food, in the manufacturing processs such as vacuum filtration, vacuum feeding, vacuum outgas, vacuum evaporation, Vacuum Concentration and vacuum conditioning, be widely used.
Summary of the invention
The liquid-ring vacuum pump unit that the purpose of this utility model improves a kind of degree of vacuum height, strong adaptability, operates steadily, noise is low.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of liquid-ring vacuum pump unit, comprise two-stage water ring pump (1), gas-liquid separator (2) and cooler (3), it is characterized in that: described two-stage water ring pump (1) is rectangular shape, two-stage water ring pump (1) is surveyed end and is connected with two intake pipes (1a), be connected with water circulating pipe (1b) on the pair of horns of upper end, be respectively equipped with admission line (1c) and gas-liquid discharge conduit (1d) on another diagonal angle, described admission line (1c) is provided with a suction valve (4), described gas-liquid discharge conduit (1d) is communicated with gas-liquid separator (2), also be provided with exhaust duct (2a) on the described gas-liquid separator (2), overflow pipe (2b) and Drainage pipe (2c), described exhaust duct (2a) is positioned at gas-liquid separator (2) top, described overflow pipe (2b) is positioned at gas-liquid separator (2) top side, pipeline is provided with a relief valve (5), described Drainage pipe (2c) is positioned at the bottom, rear of gas-liquid separator (2), Drainage pipe (2c) is communicated in cooler (3), described cooler (3) top arranges a water intake (3a), survey end a water outlet (3b) is set, a described water intake (3a) is connected on the intake pipe (3c), described water outlet (3b) is communicated with two intake pipes (1d) by outlet conduit (3d), and outlet conduit (3d) is provided with inlet valve (6).
The utility model has the advantage of: liquid-ring vacuum pump unit degree of vacuum is high, strong adaptability, when selecting suitable working medium, can extract most industrialness gas out, and vacuum pump is steady in running, and noise is low.
Description of drawings
Fig. 1 is the plan structure schematic representation of a kind of liquid-ring vacuum pump unit of the utility model.
Embodiment
As shown in Figure 1, comprise two-stage water ring pump 1, gas-liquid separator 2, cooler 3, suction valve 4, relief valve 5 and inlet valve 6.
Above-mentioned two-stage water ring pump 1, gas-liquid separator 2 and cooler 3 are installed on the base, and two-stage water ring pump 1 is positioned at the base front end, and gas-liquid separator 2 and cooler 3 are positioned at base rear end successively.
Described two-stage water ring pump 1 is rectangular shape, two-stage water ring pump 1 is surveyed end and is connected with two intake pipe 1a, be connected with water circulating pipe 1b on the pair of horns of upper end, be respectively equipped with admission line 1c and gas-liquid discharge conduit 1d on another diagonal angle, described admission line 1c is provided with a suction valve 4, described gas-liquid discharge conduit 1d is communicated with gas-liquid separator 2, also be provided with exhaust duct 2a on the described gas-liquid separator 2, overflow pipe 2b and Drainage pipe 2c, described exhaust duct 2a is positioned at gas-liquid separator 2 tops, described overflow pipe 2b is positioned at gas-liquid separator 2 top sides, pipeline is provided with a relief valve 5, described Drainage pipe 2c is positioned at the bottom, rear of gas-liquid separator 2, Drainage pipe 2c is communicated in cooler 3, described cooler 3 tops arrange two water intake 3a, survey end a water outlet 3b is set, and a described water intake 3a is connected on the intake pipe 3c, described water outlet 3b is communicated with two intake pipe 1d by outlet conduit 3d, and outlet conduit 3d is provided with inlet valve 6.
When vacuumizing, working medium water is at first sent into and is carried out condensation in the cooler 3, condensed water is in piping 1a is transported to circulating water pump 1, simultaneously with the gas in the reactor in piping 1c sucks two-stage water ring pump 1, compression enters in the gas-liquid separator 2 with water partly, and gas rises and discharges from exhaust duct 2a, liquid sinks and delivers to cooler 4 coolings from Drainage pipe 2c discharge, and it is recycling to return intake pipe 1c.
The advantages such as said system has stable, and noise is low, and degree of vacuum is high, and applicability is strong.
