Abstract
The utility model discloses a pump which avoids the vaporization of the medium, comprising a rotor inside the pump and an impeller which is arranged on the front part of the rotor 1 and is inside the pump shell 3. The utility model is characterized in that an auxiliary impeller 2 is arranged on the rear of the rotor; a radial hole 5 is arranged on the rotor body on the back part of the rotor 1. The utility model has the advantages of compact installation, no auxiliary pipeline and reliable running of the pump. The design and installation charge of the auxiliary pipelines are saved and the vaporization of the medium and the leakage phenomenon are avoided.
Description
Technical field:
The utility model relates to the employed anti-medium vaporization pump of industries such as a kind of pump, particularly a kind of chemical industry.
Background technique:
The employed no-leakage pumps of industry such as present chemical industry mostly are canned motorpump and magnetic drive pump.A rotor is arranged in pump inside, the impeller that is positioned at pump case is equipped with in the front portion of rotor, pump case is provided with the entrance and exit of medium, media a large amount of during work are directly discharged from outlet after entering the mouth, the through hole of some medium in pump enters pump housing inside, be back to outlet again and discharge, purpose is to take away the heat that motor and bearing produce.Because the part medium that enters in the pump housing is in low-pressure state, very easily vaporization, pump is caused damage, in order to address this problem, the afterbody at pump that has connects an auxiliary piping, to storage tank, to prevent that the inner generation vaporization of pump from causing pump to damage, but effect is undesirable, and this structure increased the trouble that auxiliary piping is taken into account installation to the user, with advancing also to have increased expense.
Summary of the invention:
The purpose of this utility model provide a kind of do not have auxiliary piping, can produce the anti-medium vaporization pump that high pressure prevents the medium vaporization in simple, the pump of overall structure, to overcome the deficiencies in the prior art.
Technical solution of the present utility model is: a kind of anti-medium vaporization pump, and it comprises inner rotor 1, the impeller 4 that is positioned at pump case 3 inside is equipped with in the front portion of rotor 1, it is characterized in that: the rear portion of rotor 1 is provided with auxiliary impeller 2.
The rear portion rotor body of described rotor 1 is provided with radial hole 5.
The utility model compared with prior art has the advantage of integral installation compactness, no auxiliary piping, saved the expense of auxiliary piping design, installation, and the running of pump is reliable, no medium vaporization, no leakage phenomenon.
Description of drawings:
Fig. 1, Fig. 2 are the structural representation of embodiment of the present utility model.
Embodiment:
As shown in Figure 1: 1 is the rotor in the pump, and the anterior binding of rotor 1 is connected to impeller 4, and impeller 4 is positioned at pump case 3, and pump case 3 is provided with inlet 6 and outlet 7.Being provided with through hole in pump can introduce the part working medium in the pump housing, flow to outlet again and discharge (referring to the arrow among the figure), so that the heat that is produced when taking away motor and rotary bearing work.Rear key at rotor 1 is connected with an auxiliary impeller 2, and during rotation, auxiliary impeller 2 can cause the regional supercharging of pump inside to realize circulation in the high pressure in the pump, guarantees to enter the unlikely vaporization of part medium in the pump.
In order to reach positive effect, on the rotor body at the rear portion of rotor 1, also be processed with radial hole 5 (as shown in Figure 2), effect is better.As adopt the mode of independent boring, and also can cause realizing circulation in the high pressure in the pump, guarantee to enter the unlikely vaporization of part medium in the pump.
