Abstract
The centrifugal pump self-suction jet flow is the automatic shut-off return route system, which is equipped with the backflow hole in the pump pressure header with six cross sections, bowl type valve, flow jet, with the pump induction port to form the liquid possible automatic shut-off return route system. Its principle of work is: When the pump is rotating, the pressure header can save 2/3 liquid, and the pressure produced by the impeller high-speed rotating is small, the valve at the return part is open. The partial liquids enter the jet flow circulatory system, and jet in high speed to the import, at the jet flow function pump inlet the vacuum is formed. Recycling like this. Therefore the pump efficient ratio comparing traditional self-priming pump enhances above 3%-5%.
Description
Technical field
The present invention relates to fluid machinery, refer in particular to self-priming jet automatic-closing circuit system for centrifugal pump, be mainly used in occasions such as irrigation and drainage, sewage treatment, water supply.
Background technique
At present, common self-priming pump has two kinds of structural types, a kind of self-priming structure is an external mixture type, another kind of self-priming structure is an internal-mixing, the self-priming return port of these two kinds of pumps is because of the factor of its structural principle, and after pump was finished self-priming work, the liquid of pumping chamber self-priming return port was still in circulation, therefore: cause pump efficiency low, its economic benefit is self-evident.
Summary of the invention
Finish after the self-priming work return port liquid still in circulation in order to solve existing pump, cause problems such as pump efficiency is low, the invention provides a kind of self-priming jet automatic-closing circuit system for centrifugal pump, pump is after finishing the self-priming process, the return port bowl-shaped valve at pumping chamber place can be closed automatically, liquid jetting device quits work simultaneously, and the efficient of pump improves 3%～5% than traditional self-priming pump.
The present invention solves the technological scheme that its technical problem is taked: be provided with return port, bowl-shaped valve, liquid jetting device at pumping chamber the 6th section, but form the liquid automatic-closing circuit system with Pump Suction Nozzle.Its working principle is: during the pump running, can deposit 2/3 liquid in the pumping chamber, the pressure that the impeller high speed rotating is produced is little, and the valve at pumping chamber return port place is opened, partially liq enters the liquid jetting device circulatory system, high fast direction import, the process pump inlet of jet produces vacuum, and so forth circulation, the air of pump and inlet ductwork is drained, pump is finished self-priming process and water outlet, and this moment, liquid was full of pump, and the pressure of pumping chamber reaches design load.Because valve is material preparations such as rubber, under the effect of pumping chamber pressure, the valve at return port place cuts out automatically, and the liquid jetting device circuit system quits work.Therefore the efficient of this pump has improved more than 3%～5% than traditional self-priming pump.
The beneficial effect of type of the present invention is, after pump was finished self-priming work, the valve on the liquid jetting device can cut out automatically, and the efficient of pump has improved more than 3%～5%, and the efficient height is simple in structure, easy to operate.
Description of drawings
Fig. 1 is a kind of structure principle chart of type of the present invention.
