Abstract
The utility model discloses a kind ofly increases the vacuum pump vacuum capacity, comprise nozzle, nozzle box and Diffuser, the nozzle stretched in nozzle box is installed in front end, nozzle box, rear end, nozzle box connects Diffuser, the spray plate of nozzle box is provided with nozzle, nozzle is made up of epimere nozzle and hypomere nozzle, and epimere nozzle entrance place is provided with device for preventing rotation; The multi-jet utilization of the utility model, makes distribution of steam even, and mix more even with pumped gas, stable performance, steam power loss is little, improves vacuumizing effect, and the hypomere nozzle that the design of nozzle sections formula makes wear rate higher is convenient to change.
Description
Technical field
The utility model relates to a kind of vaccum-pumping equipment used in Chemical Manufacture, specifically a kind ofly increases the vacuum pump vacuum capacity.
Background technique
Vacuum pump is large in rate of air sucked in required, operating range is wide, structure is simple, do not have the parts of relative movement, particularly it is to suction gas non-selectivity, be widely used in the occasions such as petrochemical industry, fats and oils processing, food production, demonstrating remarkable advantage compared with oil-sealed rotary pump, is a kind of broad-spectrum vaccum-pumping equipment.Steam jet vaccum nozzle arrangements traditional at present adopts single nozzle structure, and distribution of steam is uneven, poor with the mixed effect of pumped gas, affect vacuumizing effect, explosion chamber single stage compression, the fluctuation of mixed gas velocity variations is larger, pumping efficiency is low, and nozzle is easy to wear, and turnover rate is high.
Model utility content
The utility model is for above-mentioned technical problem, and aiming to provide a kind ofly increases the vacuum pump vacuum capacity.
For solving the problems of the technologies described above, the purpose of this utility model is achieved in that and a kind ofly increases the vacuum pump vacuum capacity, comprise nozzle, nozzle box and Diffuser, the nozzle stretched in nozzle box is installed in front end, nozzle box, rear end, nozzle box connects Diffuser, the spray plate of nozzle box is provided with nozzle, and nozzle is made up of epimere nozzle and hypomere nozzle, and epimere nozzle entrance place is provided with device for preventing rotation; During being arranged so that of multiple nozzle, fluid penetrates thread from each nozzle, mixes more even, improve vacuumizing effect with pumped gas; Nozzle is made up of epimere nozzle and hypomere nozzle, and the hypomere nozzle making wear rate higher is convenient to change.Device for preventing rotation can eliminate the whirlpool at nozzle entrance place, slows down nozzle wear degree.
Beneficial effect: multi-jet utilization, makes distribution of steam even, and mix more even with pumped gas, stable performance, steam power loss is little, improves vacuumizing effect, and the hypomere nozzle that the design of nozzle sections formula makes wear rate higher is convenient to change.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of nozzle;
Fig. 3 is device for preventing rotation structural representation;
Indicate in figure: 1-nozzle, 2-epimere nozzle, 3-hypomere nozzle, 4-spray plate, 5-device for preventing rotation, 6-nozzle box, 7-Diffuser.
Embodiment
Be further described the utility model below in conjunction with accompanying drawing, but must not be limited the utility model by any way, any change done based on the utility model training centre or improvement, all belong to protection domain of the present utility model.
According to Fig. 1, Fig. 2, a kind ofly increase the vacuum pump vacuum capacity, comprise nozzle 1, nozzle box 6 and Diffuser 7, the nozzle 1 stretched in nozzle box 6 is installed in front end, nozzle box 6, rear end, nozzle box 6 connects Diffuser 7, the spray plate 4 of nozzle box 6 is provided with nozzle 1, and nozzle 1 is made up of epimere nozzle 2 and hypomere nozzle 3, and epimere nozzle 2 ingress is provided with device for preventing rotation 5.
The quantity of described nozzle 1 is 3-6.
Described nozzle 1 is distributed on from spray plate 4, and distance spray plate 4 edge 10-20mm.
Described epimere nozzle 2 adopts screw thread to spin with hypomere nozzle 3.
According to Fig. 3, described device for preventing rotation 5 is a cruciform baffles agitated vessel mated with epimere nozzle 2 inlet inside diameter.
Described device for preventing rotation 5 adopts stainless steel to make.
working principle of the present utility model and working procedure as follows:
First designs of nozzles is become two-part, and spun into by screw thread nozzle-integrated, nozzle entrance place sets up defences cyclone, more some nozzles is distributed on spray plate, nozzle distance spray panel edges 10-20mm.During use, fluid penetrates thread from each nozzle, and device for preventing rotation eliminates the whirlpool at nozzle entrance place, nozzle prevents nozzle and hydroecium inwall from occurring interfering with the design of spray edges of boards distance, and do not produce interference between multiple jets, water jet kinetic energy rejection is little, increase mass transfer area, improve and make vacuum capacity.
