Abstract
The invention relates to fluid machinery, in particular to a centrifugal pump self-circulating vacuum auxiliary self-priming system with a self-priming device arranged on an inlet of a common centrifugal pump, wherein the centrifugal pump, a vacuum pump and the self-priming device form the system to make the centrifugal pump complete the self-priming process. The centrifugal pump self-circulating vacuum auxiliary self-priming system comprises six parts, namely the centrifugal pump, the vacuum pump, a large container, an internal container, a liquid level sensor and a solenoid valve. The key parts of the centrifugal pump self-circulating vacuum auxiliary self-priming system are a control element which consists of the liquid level sensor in the large container and a valve, and a self-circulating system which consists of the internal container and the vacuum pump. The centrifugal pump self-circulating vacuum auxiliary self-priming system is characterized in that the liquid level sensor is utilized to detect and control the required height of liquid level; when the liquid level is higher than the predetermined height (namely the height for the common centrifugal pump to complete the self-priming process), the valve is opened, external atmosphere enters, and the liquid level is dropped; and when the liquid level is lower than the predetermined height, the valve is closed, the vacuum pump performs vacuum pumping, and the liquid level is raised. The centrifugal pump self-circulating vacuum auxiliary self-priming system has the advantages of reliable self-priming, high automation degree, high efficiency, large flow rate, high pump lift and so on.
Description
Technical field
The present invention relates to fluid machinery, it refers in particular to a kind of centrifugal pump self-circulation vacuum auxiliary self-suction system that adds a self-priming apparatus in the Ordinary Centrifugal Pumps import.Form a system by centrifugal pump, vacuum pump, self-priming apparatus, make centrifugal pump finish self-priming.
Background technique
Centrifugal pump is a kind of machinery that has a large capacity and a wide range.Be widely used in irrigating, the family expenses water delivery, blowdown, well water extracts, the draining of building site, occasions such as phreatic extraction.But when Ordinary Centrifugal Pumps starts, air is arranged in the pump case, because air density is much smaller than fluid density, the centrifugal force of generation is little, and the formed low pressure in impeller center is not enough in the liquid suction pump.This air sinuses phenomenon shows that centrifugal pump does not have suction capacity, so need to pour water in advance before startup or add a self-priming apparatus.
There are two kinds of methods can make the centrifugal pump import form vacuum, thereby make centrifugal pump finish self-priming.1. the centrifugal pump import set up one the band Venturi tube the self-loopa sparger 2. vacuum pump vacuumize.When the centrifugal pump pump is carried different medium, also different to the requirement of sparger, especially when extracting sewage, be easy to cause the obstruction of sparger, the pump cisco unity malfunction.The employing vacuum pump vacuumizes, and self-priming is reliable, but its stability is easy to be subjected to the influence of various factors.In actual applications, the liquid that is extracted may contain solid particles such as silt, handstone, chip, enters behind the vacuum pump and can destroy vacuum pump.So the reliability of self-priming apparatus needs further to improve.
Summary of the invention
The purpose of this invention is to provide a kind of stable and reliable operation, centrifugal pump self-circulation vacuum auxiliary self-suction system that efficient is high, be China's discharge of industrial wastes, town water supply, large-scale irrigated area, fields such as small pumping station provide the product of high-quality.
The technical solution adopted for the present invention to solve the technical problems is: comprise centrifugal pump, vacuum pump, bulk container, internal container, liquid level sensor, solenoid valve six parts, it is characterized in that being placed on liquid level sensor and the control unit of solenoid valve composition and the self-circulation system of internal container and vacuum pump composition in the bulk container, liquid level sensor links to each other with solenoid valve, the switch of control electromagnetic valve; The internal container and the vacuum pump that are positioned in the bulk container form self-loopa by liquid-transport pipe-line and blowdown piping.
Wherein motor links to each other with vacuum pump with centrifugal pump respectively with cone gear by speed reducer, and internal container links to each other with vacuum pump by liquid-transport pipe-line, and vacuum pump links to each other with centrifugal pump with bulk container by pump-line; Vacuum pump links to each other with internal container by blowdown piping, and internal container is provided with and the extraneous relief opening that communicates.
Liquid level sensor control electromagnetic valve in the control unit is kept height needed.When liquid level is higher than predetermined altitude (being the height that Ordinary Centrifugal Pumps is finished self-priming), valve open, logical ambient atmosphere, liquid level descends; When liquid level is lower than predetermined altitude, valve closing, vacuum pump vacuumizes, and liquid level rises.Internal container in the self-circulation system provides vacuum pump water, makes vacuum pump normally to move, and the gas that vacuum pump extracts is discharged via internal container, and the water of extraction is accumulated in the internal container, moves usedly for vacuum pump next time, promptly reuses water resources.
The present invention compares with traditional gas-liquid mixed formula self-priming pump, has that self-priming is reliable, automaticity is high, efficient is high, flow is big, the lift advantages of higher; " PUMP SYSTEM WITH VACUUM SOURCE " compares and reduced cost with U. S. Patent, reduced energy loss, optimized structure.And the model size according to centrifugal pump is used in different occasions, uses more extensive.As blowdown, farmland pour water, small pumping station etc.

Embodiment
Centrifugal pump self-circulation vacuum auxiliary self-suction system comprises centrifugal pump, vacuum pump, bulk container, internal container, liquid level sensor, solenoid valve six parts.Key component of the present invention is liquid level sensor and the control unit of valve composition and the self-circulation system of internal container and vacuum pump composition that is placed in the bulk container.Vacuumize the principle that causes pressure reduction by vacuum pump, make centrifugal pump can finish self-priming.
Working procedure is: motor (1) links to each other with vacuum pump (15) with centrifugal pump (4) respectively with cone gear (3) by speed reducer (2), and drives centrifugal pump and vacuum pump running simultaneously.Internal container (7) links to each other with vacuum pump (15) by liquid-transport pipe-line (16), and vacuum pump water is provided, and vacuum pump can normally be moved.Vacuum pump (15) links to each other with centrifugal pump (4) with bulk container (6) by pump-line (13).After the normal operation of vacuum pump,, extract bulk container (6), centrifugal pump (4) by pump-line (13), and the gas in the centrifugal pump inlet pipeline, because the effect of pressure reduction makes the water surface to rise.Meanwhile, vacuum pump (15) links to each other with internal container (7) by blowdown piping (14), and the gas that vacuum pump (15) extracts arrives internal container (7) through blowdown piping (14), is discharged into the external world by relief opening (12) again.The liquid that vacuum pump extracts then is accumulated in the internal container, if liquid contains solid particles such as silt, stone, is easy to be deposited on the sewage draining exit place by the bottom surface that has tapering, and discharges by sewage draining exit (5).When liquid level sensor (10) detected liquid level arrival predetermined altitude (being that centrifugal pump is finished self-priming), liquid level sensor control valve (9) was opened, logical ambient atmosphere.Make liquid level maintain this height.Centrifugal pump just can proper functioning like this.After the centrifugal pump proper functioning, driving lever (17) is stirred splined shaft (18), makes two cone gears separate, and vacuum pump quits work, and has reduced energy loss.
