Abstract
The utility model relates to a positive displacement diaphragm pump drainage self-priming pump with an improved vacuum line layout. The positive displacement diaphragm pump drainage self-priming pump comprises a centrifugal pump and a positive displacement diaphragm pump drainage system, wherein the positive displacement diaphragm pump drainage system is airtightly connected with the outlet or inlet line of the centrifugal pump through a liquid level line; a gas-guide balance pipe is arranged between the volute chamber of the centrifugal pump and the positive displacement diaphragm pump drainage system. The utility model provides a vacuum line gas-guide balance pipe layout scheme which is extremely effect and is strong in reliability for the positive displacement diaphragm pump drainage self-priming pump, thereby, the problems that gas hold-up and water diversion failure in the volute chamber often occur in the positive displacement diaphragm pump drainage self-priming pump are thoroughly solved, and the operational reliability of equipment is enhanced.
Description
Technical field
The utility model relates to a kind of water pump drainage system, specifically a kind of positive displacement pumps drainage self-priming pump that improves the vacuum line layout.
Background technique
In recent years, a kind of work manufacturing vacuum of utilizing the positive displacement pumps device occurred for the water pump diversion also is combined into a kind of self-priming pump device with suction capacity with this device and water pump, be: positive displacement pumps drainage self-priming pump in China.This kind self-priming pump device is used in places such as part industrial and mining enterprise, urban water supply and sewerages.But, find that in application this kind equipment exists some defectives, cause frequent diversion failure causes pump device normally not move.Fig. 1 is a single-stage double-suction positive displacement pumps drainage self-priming pump of the prior art, and Fig. 2 is an one step single sucking positive displacement pumps drainage self-priming pump of the prior art.Its failure reason analysis is following: the positive displacement pumps drainage system of positive displacement pumps drainage self-priming pump links to each other with the centrifugal pump inlet pipe through the liquid level pipeline; Can clearly learn through accompanying drawing; When the volute chamber of centrifugal pump and pump intake diameter contrast differences are big; Positive displacement pumps drainage self-priming pump has in the volute chamber of the centrifugal pump of a big chunk gas hold-up more than being higher than the pump intake diameter when starting drainage; The startup under this state of positive displacement pumps drainage self-priming pump will can't form necessary centrifugal effect because of medium underfill pump chamber, and causing startup to fail can't output medium.
Summary of the invention
The utility model is to the problem that exists in the above-mentioned existing technology; A kind of positive displacement pumps drainage self-priming pump is provided; The vacuum line layout is improved, efficiently solved the problem that the diversion inefficacy often occurs that exists in the above-mentioned existing technology, increased the equipment operation reliability simultaneously.
The technological scheme of the utility model is:
Comprise centrifugal pump, the positive displacement pumps drainage system, the positive displacement pumps drainage system is tightly connected with centrifugal pump outlet or inlet pipe through the liquid level pipeline mutually; Between centrifugal pump volute chamber and positive displacement pumps drainage system the air guide balance tube is set.
One end of described air guide balance tube is connected the suction port of positive displacement pumps drainage system, and the other end of air guide balance tube is connected centrifugal pump volute chamber peak.
The advantage of the utility model is following:
A kind of vacuum line air guide balance tube arrangement of highly effective good reliability is provided for positive displacement pumps drainage self-priming pump; Thereby thoroughly solve the disadvantage that gas hold-up in the volute chamber, diversion inefficacy often appear in positive displacement pumps drainage self-priming pump, increase the equipment operation reliability.

Embodiment
Following with reference to accompanying drawing, in conjunction with specific embodiment, the utility model is elaborated as follows.
Embodiment 1
As shown in Figure 3, the utility model adopts single-stage double-suction positive displacement pumps drainage self-priming pump.Comprise centrifugal pump 2, positive displacement pumps drainage system 3, positive displacement pumps drainage system 3 is tightly connected with centrifugal pump 2 outlets or inlet pipe through liquid level pipeline 1 mutually; 3 of centrifugal pump 2 volute chambers and positive displacement pumps drainage systems are provided with air guide balance tube 4.One end of described air guide balance tube 4 is connected the suction port of positive displacement pumps drainage system 3, and the other end of air guide balance tube 4 is connected centrifugal pump volute chamber peak 5.
As shown in Figure 4, the utility model adopts one step single sucking positive displacement pumps drainage self-priming pump.Its structure is with embodiment 1.
The working principle of the utility model is following:
When the volute chamber of centrifugal pump and pump intake diameter contrast differences are big; Because former positive displacement pumps drainage system links to each other with the centrifugal pump inlet pipe through the liquid level pipeline; When the pump startup drainage, have a big chunk gas hold-up and be higher than in the volute chamber of the centrifugal pump more than the pump intake diameter, can't be discharged from.Adopt the utility model technological scheme after connecting the air guide balance tube between peak to the positive displacement pumps drainage system of the volute chamber of centrifugal pump, discharge after the gas that just is detained in the volute chamber with centrifugal pump smoothly is transferred to the positive displacement pumps drainage system.
Claims (2)
1. positive displacement pumps drainage self-priming pump comprises centrifugal pump, the positive displacement pumps drainage system, and the positive displacement pumps drainage system is tightly connected with centrifugal pump outlet or inlet pipe through the liquid level pipeline mutually; It is characterized in that between centrifugal pump volute chamber and positive displacement pumps drainage system the air guide balance tube being set.
2. positive displacement pumps drainage self-priming pump according to claim 1 is characterized in that an end of described air guide balance tube is connected the suction port of positive displacement pumps drainage system, and the other end of air guide balance tube is connected centrifugal pump volute chamber peak.
