Abstract
The utility model discloses a low water pressure two-stage water air sucking pump and a high water pressure two-stage water air sucking pump. The low water pressure two-stage water air sucking pump and a high water pressure two-stage water air sucking pump respectively comprise an upper air sucking nozzle, a lower air sucking nozzle, a one-stage jet nozzle, and a two-stage jet nozzle which is cocentric with the one-stage jet nozzle. The upper end of a diffusion pipe of the lower water pressure two-stage water air sucking pump is extended towards the interior of a vacuum cavity to the lower end of the two-stage jet nozzle. The upper end of a water outlet pipe of the high water pressure two-stage water air sucking pump is extended towards the interior of the vacuum cavity to the lower end of the two-stage jet nozzle. The lower end of the two-stage jet nozzle is provided with a buffer with a water outlet nozzle. The low water pressure two-stage water air sucking pump and the high water pressure two-stage water air sucking pump have simple structures, easy fabrication, and low cost. When the low water pressure two-stage water air sucking pump and the high water pressure two-stage water air sucking pump are used, the noise of the low water pressure two-stage water air sucking pump and a high water pressure two-stage water air sucking pump is low. The low water pressure two-stage water air sucking pump and the high water pressure two-stage water air sucking pump are respectively suitable for water pressure below 1 kilogram and a circulation water pump.
Description
The utility model relates to the water extraction pump, specifically is exactly the secondary water extraction pump that the secondary water extraction pump used of a kind of low hydraulic pressure and a kind of high hydraulic pressure are used, and belongs to vacuumize Instrument technology field.
The water extraction pump that glass is made is low because of its cost, make simply be widely used in imparting knowledge to students, scientific research, medicine, chemical industry, and the laboratory and the production unit of other many industrial enterprises.Existing secondary water extraction pump is mainly structure shown in Figure 1, but this class pump then can not satisfy usage requirement when the requirement of bleeding is faster, all inapplicable to low hydraulic pressure below 1.5 kilograms and the high hydraulic pressure more than 3 kilograms, few at water pump in addition, the water source is few, the user of service can not need for a long time enough, and the splash phenomenon in outlet port can not solve always, the noise that the outlet port produces during use is big, if put rubber tube at water outlet, though can reduce noise, but come off easily, therefore can not tackle the problem at its root.
Patent ZL85200097.9 provides a kind of secondary water extraction pump of three air intakes, and this pump has partly solved the existing deficiency of above-mentioned extraction pump, but yet has other problem, as manufactures trouble etc.
For overcoming the above-mentioned deficiency of prior art, the purpose of this utility model is to provide a kind of novel low hydraulic pressure secondary water extraction pump and a kind of novel high hydraulic pressure secondary water extraction pump, these two kinds of water extraction pumps should be simple in structure, easy to make, bleed during use fast, noise is little, and can be applicable to different hydraulic pressure environment.
For realizing that the technological scheme that above-mentioned purpose of the present utility model is taked is:
The working principle of two kinds of secondary water extraction pumps provided by the utility model is the same, all is to utilize jet current principle, produces vacuum chamber by jet, thereby reaches the purpose of bleeding.Specify as follows:
1. the secondary water extraction pump that low hydraulic pressure is used: it comprises upper and lower two mouths of bleeding, first order jet nozzle, secondary nozzle, the diffusing tube concentric with first order jet nozzle, but the upper end of diffusing tube extends to the lower end of secondary nozzle and forms a toroidal in vacuum chamber.
2. the secondary water extraction pump that high hydraulic pressure is used: it comprises upper and lower two mouths of bleeding, first order jet nozzle, the secondary nozzle concentric with first order jet nozzle, but the outlet pipe of extraction pump upper end extends to the lower end of secondary nozzle and forms a toroidal in vacuum chamber, the lower end is a buffer that is similar to elliposoidal, at the sidewall near the buffer bottom water outlet is arranged.
According to different needs, materials such as various glass, plastics, metal can be as the material of making the utility model secondary water extraction pump.
Compared with the prior art, obtained beneficial effect after the employing the technical solution of the utility model:
Two kinds of secondary water extraction pumps provided by the utility model are simple in structure, make easily, and can be made into the water extraction pump of all size specification according to user's requirement, cost of production is low, and the noise during use is little, and pumping speed is fast, the degree of vacuum height, suitable hydraulic pressure model circle is wide.Low hydraulic pressure is not only applicable to normal water with secondary water extraction pump and presses, and also is specially adapted to 0.3～1 kilogram low hydraulic pressure situation; High hydraulic pressure secondary water extraction pump is particularly suitable for hydraulic pressure in the water environment of using more than 3 kilograms, as is used in the circulating water extraction pump except that being applicable to normal hydraulic pressure.
Description of drawings:
Fig. 1 is the structural representation of existing secondary water extraction pump;
The structural representation of the secondary water extraction pump that Fig. 2 uses for the low hydraulic pressure of the utility model;
The structural representation of the secondary water extraction pump that Fig. 3 has for the high hydraulic pressure of the utility model.
Below in conjunction with accompanying drawing and specific embodiment the technical solution of the utility model is further described: embodiment 1: the secondary water extraction pump that low hydraulic pressure is used
The secondary water extraction pump that low hydraulic pressure is as shown in Figure 2 used, comprise upper and lower two mouths of bleeding, first order jet nozzle (1), secondary nozzle (2), the diffusing tube (3) concentric with first order jet nozzle, the upper end of diffusing tube extends to the lower end of secondary nozzle (2) in vacuum chamber, and forms a toroidal (4).Make promptly obtaining the secondary water extraction pump that low hydraulic pressure is used in a manner described, this pump can use for two people simultaneously.Embodiment 2: the secondary water extraction pump that high hydraulic pressure is used
The secondary water extraction pump that high hydraulic pressure is as shown in Figure 3 used, comprise upper and lower two mouths of bleeding, first order jet nozzle (5), the secondary nozzle (6) concentric with first order jet nozzle, the upper end of the outer pipe of extraction pump extends to the lower end of secondary nozzle (2) in vacuum chamber, and form a toroidal (9), the lower end of outlet pipe is a buffer (7) that is similar to elliposoidal, at the sidewall near the buffer bottom water outlet (8) is arranged.This extraction pump is particularly suitable for the high hydraulic pressure environment more than 3 kilograms, is installed in the circulating water extraction pump, and pumping speed is fast, can use simultaneously for many people.
