Abstract
The utility model relates to a water supply device of a water pump without a bottom valve, and relates to a water supply device. The water supply device comprises a centrifugal water pump, an air evacuation valve, a water tank, a small water pump, an air extraction ejector and a covered reservoir, wherein an inlet pipe of the centrifugal water pump is connected with the covered reservoir; one end of the air evacuation valve is connected between the centrifugal water pump and an outlet pipe of the pump, the other end of the air evacuation valve is connected with the air extraction ejector, and one end of the air extraction ejector is connected with one end of the water tank; and the other end of the water tank is connected with one end of the small water pump, and the other end of the small water pump is connected with the other end of the air extraction ejector. According to the utility model, a bottom valve is taken off so as to reduce the resisting force of a suction pipe, the flow is increased, the efficiency and the suction lift of the water pump are improved, the power loss of the water pump is reduced, the operation is reliable, the maintenance cost is reduced, failure influencing the normal running of the bottom valve can be excluded, the operation is simple, the operation is reliable, the installation reconstruction is easy, and the water pump and a pipeline do not need to be changed.
Description
Technical field:
The utility model relates to a kind of water supply installation, is specifically related to a kind of without bottom valve water pump water supply installation.
Background technology:
Centrifugal water pump generally can not self-priming, and when water level was lower than the water pump top, prestart must be filled liquid in pump and intake duct, and centrifugal pump could operate as normal.
The utility model content:
The purpose of the utility model provides a kind of without bottom valve water pump water supply installation, it can realize water pump without bottom valve operation have simple to operate, reliable, install and transform easily, do not need characteristics such as water pump and pipeline changes.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises centrifugal water pump 1, extraction valve 2, water tank 3, little water pump 4, the ejector 5 of bleeding, underground tank 6; The inlet tube of centrifugal water pump 1 is connected with underground tank 6; One end of extraction valve 2 is connected between centrifugal water pump 1 and the pump discharge pipe; The other end is connected with the ejector 5 of bleeding; The end of ejector 5 of bleeding is connected with an end of water tank 3, and the other end of water tank 3 is connected with an end of little water pump 4, and the other end of little water pump 4 is connected with the other end of the ejector 5 of bleeding.
The utility model adopt to spray the machine assembly air-exhausting water absorber, to pump chamber and the inlet tube formation negative pressure of bleeding, makes water be full of pump chamber by atmospheric pressure, and just can start needs the water pump that moves.
The utility model takes down the resistance that bottom valve can reduce suction water pipe, and flow increases, and improves the efficient and suction journey of water pump; Reduce the power attenuation of water pump; Reliable operation both can reduce maintenance cost, can get rid of again because of the bottom valve fault effects and normally move; Have simple to operate, reliable, install to transform easily, do not need water pump and pipeline are changed.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Referring to Fig. 1, this specific embodiment adopts following technical scheme: it comprises centrifugal water pump 1, extraction valve 2, water tank 3, little water pump 4, the ejector 5 of bleeding, underground tank 6; The inlet tube of centrifugal water pump 1 is connected with underground tank 6; One end of extraction valve 2 is connected between centrifugal water pump 1 and the pump discharge pipe; The other end is connected with the ejector 5 of bleeding; The end of ejector 5 of bleeding is connected with an end of water tank 3, and the other end of water tank 3 is connected with an end of little water pump 4, and the other end of little water pump 4 is connected with the other end of the ejector 5 of bleeding.
This specific embodiment before the outlet valve of centrifugal pump, take over and mounted valve to spraying the machine assembly air-exhausting water absorber, little water pump supplies water through the water tank malleation after the starting, produces press water and makes the low-pressure fuel injection pump work that is contained on the pipeline, forms negative pressure pump chamber is bled.The gas-vapor mix reflow tank recycles then.Do not have under the situation of seepage at pipeline and pump, valve, it is about more than 1 minute to start water jet pump, can make the water pump pump chamber be full of water, just can start the water pump that needs operation.And one is sprayed unit and can bleed to many water pumps, as long as the water pump exhaust opening is connected in parallel on the exhaust tube, opens low pressure valve separately, just can bleed to water pump, when reaching certain vacuum and spend, just can start water pump operation.
This specific embodiment takes down the resistance that bottom valve can reduce suction water pipe, and flow increases, and improves the efficient and suction journey of water pump; Reduce the power attenuation of water pump; Reliable operation both can reduce maintenance cost, can get rid of again because of the bottom valve fault effects and normally move; Have simple to operate, reliable, install to transform easily, do not need water pump and pipeline are changed.
