Abstract
The utility model relates to a self-suction auxiliary device of a centrifugal pump, and the utility model comprises a closed container. The container separates into a water storage chamber and a water suction chamber via an obstruct, and a communicating pipe is arranged between two chambers. A water inlet of a water pump connected with the water suction chamber and a water outlet is separately connected with the communicated water storage chamber, the upper part of an air-water separator tube is provided with a water return hole, and a suction lift tube is communicated with the water inlet of the water pump via the water suction chamber. The utility model has the advantages of simple structure, which reduces prestarting labor strength of water pumps.
Description
The utility model relates to a kind of self-priming auxiliary device of centrifugal pump, existing centrifugal pump especially small pump all must be manually just can be started working inhaling in the journey pipe and the pump housing fills with water at prestart, and also bottom valve must be installed inhaling journey pipe bottom, so that unlikely race is leaked when pouring water.Consuming time the delaying work of starting preparatory work of this water pump, labor intensity is big, especially places the pump of field work, and it is unclean to inhale the water-break of journey pipe winter, is easy to freeze, and freezing pipeline influences work
91224542.5 liters of Chinese patents a kind of water storage box type self-priming pump, this self-priming pump is to set up a water storage box outside pump, the intake pipe of centrifugal pump and water storage box bottom are connected, the water inlet pipe mouth of water storage box is at the water storage box top.The effluent pipe mouth of water pump and the water inlet pipe mouth of water storage box are the purpose of water outlet though the pump of this structure has been realized turn on pump on same horizontal line, and it can only be applicable to miniature pump, and is unsuitable for the facility of field work.Also having a kind of self-priming pump is that impeller outer is installed an aqueous vapor separation dividing plate in outlet pipe, there is a slit in the dividing plate outside, be communicated with intake pipe, during the starting water pump, water in the pump case is at first thrown away by impeller, during air-water mixture process air-water separation dividing plate, because air density is little, air is just discharged from water outlet, water flows back to again the slit outside dividing plate in the pump, and this self-priming pump needs nearly ten minutes or longer time from the starting water pump during to water outlet, and, owing to the slit of connection is arranged, between intake pipe and outlet pipe so efficient is lower than Ordinary Centrifugal Pumps.
The purpose of this utility model is in order to overcome above-mentioned deficiency, to provide a kind of simple in structure, and the low water outlet efficient of cost is higher, the centrifugal pump that Applicable scope is wider, auxiliary self-priming apparatus.
The utility model comprises the container of a sealing, container is provided with and is used for the connection set that combines with pump water inlet and outlet pipe, there is a dividing plate that container is divided into water chamber and suction chamber in the container, between water chamber and suction chamber, a connecting pipe is arranged, inhaling the journey pipe communicates with pump water inlet by suction chamber, in water chamber, have one to connect this chamber and at the air-water separation pipe that is equipped with backwater hole near the water chamber upper part, one end of this air-water separation pipe links to each other with pumping line, and the other end is a water outlet.
The utility model is simple in structure, and cost is low, can realize that turn on pump is the purpose of water outlet, and water outlet efficient height has wider applied value.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the auxiliary self-priming apparatus plan view of water pump
Fig. 2 is the auxiliary self-priming apparatus plan view of water pump
With reference to accompanying drawing, the utility model comprises the container of a sealing, container is provided with and is used for the connection set (1 that combines with pump water inlet and outlet pipe, 7), in container, there is a dividing plate (5) that container is divided into water chamber (10) and suction chamber (11), a connecting pipe (4) is arranged between water chamber and suction chamber, inhaling journey pipe (6) communicates with pump water inlet mouth (7) by suction chamber (11), in water chamber (10), have one to connect this chamber and at the air-water separation pipe (3) that is shaped on backwater hole near the water chamber upper position, one end of this air-water separation pipe (3) links to each other with pumping line (1), and the other end is a water outlet.
During use, exit of pump is joined with connection set (7,1) respectively, fill water in water chamber (10), connect pump power, and open valve (8), water flows into suction chamber from water chamber, by water pump with the water that flows into together with the air in the suction chamber.In the suction air-water separation pipe (3), air is drained through water outlet from the air-water separation pipe, and water flows back to water chamber again through backwater mouth (2), so, through very short time, the operation of the air emptying water pump in the suction journey pipe can normally can being drawn water.
Use water pump self-suction device of the present utility model when starting, only need in water chamber, to add seldom a part of water, can make the water outlet of water pump proper functioning, thereby the labor intensity when having significantly reduced starting, and can remove and inhale journey pipe bottom valve, steel is inhaled the journey pipe use the plastic tube replacement fully instead, reduce expenses, reduce and inhale the journey loss.
Claims (2)
1, a kind of water pump self-suction device, the container that comprises a sealing, container is provided with and is used for the connection set (1 that combines with pumping line and intake pipe, 7), it is characterized in that having in the container dividing plate (5) that this container is divided into water chamber (10) and suction chamber (11), a connecting pipe (4) is arranged between water chamber and suction chamber, inhaling journey pipe (6) communicates with pump water inlet by suction chamber (11), in water chamber (10), have one to connect this chamber and at the air-water separation pipe (3) that is shaped on backwater hole (2) near the water chamber upper position, one end of this air-water separation pipe links to each other with pumping line, and the other end is a water outlet
2, water pump self-suction device as claimed in claim 1 is characterized in that described connecting tube (4) is provided with valve (8).
