Abstract
Air -spray vacuum pump relates to the vacuum pump field. Mainly be that to have air inlet progression limited in order to solve current air -spray vacuum pump, bulky scheduling problem designs. Comprising a housin, there is the compressed air air inlet that is linked together with the compressed gas distributor chamber on the pump cover of casing, there is the vacuum induction port on the casing, there is venturi in the casing, venturi's top is linked together with the gas outlet of compressed air distributor chamber, the outside cover of venturi has the outer tube, the indoor vacuum air inlet that is equipped with takes place for the vacuum that forms between outer tube and the venturi, the outer tube is equipped with the negative pressure air inlet, be equipped with the check valve on the venturi pipe wall, the casing below has venturi to fix the disk seat, venturi's bottom is fixed in the venturi fixing hole on the fixed disk seat of venturi, venturi is fixed, and the disk seat below is equipped with the base, be equipped with gas exhaust port on the base. The advantage is the progression that can set up the air inlet wantonly, and is small.
Description
Technical field:
The utility model relates to field of vacuum, specifically relates to a kind of air-spray vacuum pump.
Background technique:
Vacuum pump refers to and utilizes machinery, physics, chemistry or physicochemical method to be bled and the device or the equipment that obtain vacuum to taking out container, and it is widely used in the industries such as metallurgy, chemical industry, food.
There is suction port progression and be restricted in existing air-spray vacuum pump, unreasonable owing to designing, and Venturi tube is difficult to ensure concentricity.Volume is large, weight is large, energy loss is large, be difficult to solve the problems such as environmental issue, efficiency are low, inconvenient maintenance.
Summary of the invention:
Technical problem to be solved in the utility model is to provide one can arrange arbitrarily suction port progression, and volume is little, lightweight air-spray vacuum pump.
Above-mentioned purpose is achieved in that it comprises housing, case top has pump cover, the pressurized air distributor chamber of annular is provided with in pump cover, pump cover is also provided with the compressed air inlet port be connected with the pressurized gas distributor chamber of annular, housing is provided with vacuum suction mouth, several Venturi tubes are provided with in housing, the pressurized air distributor chamber of annular is provided with the air outlet identical with Venturi tube quantity, the pressurized air distributor chamber of annular can make the pressure uniform of each air outlet, the top of described each Venturi tube is connected with each air outlet of the pressurized air distributor chamber of annular respectively, Venturi tube outer cover is provided with complete outer sleeve, several vacuum generation chamber are formed between outer sleeve and Venturi tube, the vacuum inlet be connected with Venturi tube inner passage is provided with in vacuum generation chamber, outer sleeve is all provided with negative pressure inlet mouth at correspondence each vacuum generation chamber place, Venturi tube tube wall near negative pressure inlet mouth is provided with safety check, each negative pressure inlet mouth of outer sleeve blocks by safety check, the setting of complete outer sleeve ensure that the concentricity of Venturi tube, space in housing between each outer sleeve is vacuum mixing chamber, Venturi tube fixed valve base is provided with below housing, Venturi tube fixed valve base is provided with the Venturi tube fixed via identical with Venturi tube quantity, the bottom of described each Venturi tube is fixed in each Venturi tube fixed via, base is provided with below Venturi tube fixed valve base, base, Venturi tube fixed valve base is connected with housing by connecting bolt, base is provided with exhaust port.
The utility model has the advantages that: during work, pressurized gas enters into pressurized gas distributor chamber from pressurized gas suction port, then each air outlet high velocity jet of compressed gas distributing chamber enters in each Venturi tube, the gas entered in vacuum mixing chamber from vacuum suction mouth is hugged away, and produces negative pressure.The each negative pressure inlet mouth of gas in vacuum mixing chamber on outer sleeve enters in each vacuum chamber, and the vacuum inlet in vacuum chamber enters in Venturi tube, discharges thus obtain vacuum together with pressurized gas from exhaust port.Advantage in Venturi tube, can arrange arbitrarily multiple vacuum chamber at the whole pump housing highly constant and establish multiple suction port on vacuum generation chamber outer sleeve, Venturi tube good concentricity, vacuumizing effect is all right, structure is simple, volume is little, lightweight, easy for installation, easy-maintaining, applied widely.Due to the design (sleeve pipe is integrated) that Venturi tube outer sleeve is complete, thus solve the concentricity issues produced because of segmentation of Venturi tube, increase the progression of suction port, improve the speed of exhaust, reach reasonable in design.Being suitable for various gas is working material, and using scope is extensive.
