Abstract
The invention provides a self-priming booster pump. The self-priming booster pump is characterized in that a centrifugal pump is driven by a centrifugal pump motor and mounted on the ground together with a self-priming tank. A turbine pump is composed of a water pump and a turbine and installed in a liquid storage tank. The turbine pump is installed under liquid level. The centrifugal pump fills medium into the self-priming tank before running. The centrifugal pump motor is started to pump the medium in the self-priming tank. The medium outflows from the outlet of the centrifugal pump after the centrifugal pump is filled with the medium. A part of the medium enters an outlet pipeline of the centrifugal pump. A part of the medium enters a backflow pipeline as a power source of the turbine pump to push a wheel of the turbine to work. The medium in the liquid storage tank is delivered to an inlet pipeline of the centrifugal pump so as to overcome that common centrifugal pumps cannot suck the medium due to gasification of the medium. The self-priming booster pump has the advantages that without extra power consumption, the motor which is soaked in the medium for a long time is protected from current leakage, processing difficulty is reduced, equipment stability is high, maintenance times and cost are reduced. Once pump priming without filling again in the whole service life is realized.
Description
Technical field
The present invention relates to a kind of novel
the power-assisted self-priming pump,particularly the inflammable and explosive easy vaporized media such as a kind of light sump oil, high-temperature water and the liquid container degree of depth exceed the Ordinary Centrifugal Pumps suction head, and Ordinary Centrifugal Pumps can't suct the operating mode of medium.
Background technique
Put on operating mode under liquid and mainly take at present following several mode: 1, long shaft submerged pump, during this pump startup, impeller is immersed in medium, thereby starts easily, does not have exhaust and the problem of finding time, and does not need to consider the problem of suction lift and is used widely.Because of its motor, on liquid level, rotor part is under liquid level, and the long difficulty of processing that causes of axle is large, and the pump shaft amplitude of fluctuation is amplified, so bearing life is short, frequency of maintenance is high.Because axle is long, so adopt the multiple spot sliding bearing to support, once sliding bearing is lubricated bad, dry grinding easily produces spark.When medium is the inflammable and explosive medium such as light sump oil, very easily ignite flammable explosive gas in tank, initiation fire, these several years Frequent Accidents especially, affect very large.2, this pump of common self-priming pump is the negative pressure self-suction feed flow, and suction head is subject to the restriction of local barometric pressure and the net positive suction head of pump own, can't realize that easy vaporized media, the liquid container degree of depth reach the medium transport of tens meters.3, this pump pump head of submerged pump and motor all are immersed in medium, and motor easily leaks electricity, the Security extreme difference.The light large various flow of sump (waste oil) pump is very little, and the minimum regime flow that the existing pump design discharge requires much larger than light sump (waste oil) pump is causing pump motor vibration, noise increase, pump component to damage for a long time lower than pump minimum discharge point work meeting.Often choose high-capacity pump for meeting working condition requirement, distribute a part at pump discharge and get back in liquid container.This part energy wastes.The inflammable and explosive easy vaporized medias such as a kind of light sump oil, high-temperature water and the liquid container degree of depth exceed the Ordinary Centrifugal Pumps suction head, and Ordinary Centrifugal Pumps can't suct the operating mode of medium.
Summary of the invention
The purpose of invention is the deficiency existed in above-mentioned technology, provides
a kind ofly by turbine pump, self-sucking pot and centrifugal pump, formeda kind of
the power-assisted self-priming pump,the water that takes full advantage of the part medium of pump discharge backflow can provide a kind of novel combined self-priming pump reliably as turbine pump power, overcomes the deficiency existed in current technology.
The object of the present invention is achieved like this: comprise
turbine pump, self-sucking pot and centrifugal pump, it is characterized in that, centrifugal pump is driven by centrifugal pump motor, together with self-sucking pot, installs on the ground, and turbine pump is formed and is arranged in liquid container by water pump and water turbine two parts..Turbine pump is a kind of water lift that directly utilizes the water energy, by water, promotes runner in water turbine and rotates, and makes water can be converted into mechanical energy, drives pumping for water pump.First will fill medium in self-sucking pot before centrifugal pump operation, self-sucking pot provides the medium started first to centrifugal pump, make centrifugal pump very high at the medium vapor pressure, can't suct under normal circumstances under the condition of medium and be run well.After being full of medium in centrifugal pump, from outlet of centrifugal pump, discharge, a part of medium enters the outlet of centrifugal pump pipeline, and a part enters reflux pipeline and promotes the runner work of water turbine as the power source of turbine pump.Runner provides mechanical energy for water pump, carries in liquid container medium to the centrifugal pump suction line, because of medium, gasifies when making up easy vaporized medias such as extracting light sump oil, and Ordinary Centrifugal Pumps can't suct the defect of medium.
Beneficial effect of the present invention: 1, the power-assisted self-priming pump sucts formula by the means of transportation of medium by the negative pressure of Ordinary Centrifugal Pumps and changes turbine pump malleation propelling movement type into, has avoided medium to suct in process and has vaporized because of the liquid level pressure decreased, and centrifugal pump can't suct medium; 2, turbine pump can be done power by the part water of outlet of centrifugal pump shunting, without the extra electric energy that consumes, has also avoided causing electric leakage because of the motor long period of soaking in medium; 3, turbine pump to centrifugal pump, makes the suction head of whole equipment become the suction head of turbine pump lift+centrifugal pump at the Under Water Pumps fed sheet of a media, has made up the shortcoming of Ordinary Centrifugal Pumps suction head deficiency, has widened the using scope of Ordinary Centrifugal Pumps; 4, turbine pump is that common pipeline is connected with the Placement of centrifugal pump, compares difficulty of processing with long shaft submerged pump and greatly reduces, and stabilization of equipment performance improves, and maintenance frequency is few, has reduced maintenance expenses.5, increase self-sucking pot before centrifugal pump, realized that pump priming exempts to annotate all the life, only need when using for the first time, to self-sucking pot, fill with medium, do not need pump priming later.
