Description
Technical field
The utility model relates to a kind of centrifugal pump, especially designs a kind of centrifugal pump with high suction depth.
Background technique
The suction journey of general single stage centrifugal pump is about 6 meters, when running into when inhaling journey greater than 6 meters situation, often need storage tank be installed in the centre, transfer liquid several times, so not only increase more equipment, fitting operation is cumbersome, cost is higher, but also requires no-float between each pump, in case fault appears in middle certain pump, just influences the work of whole liquid transfer system.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of centrifugal pump device of high suction depth.
High suction depth centrifugal pump device of the present utility model, comprise: centrifugal pump, pick-up tube, pipe pressurizing pump and unidirectional bottom valve, described pick-up tube is communicated with the pump entrance sealing, and described pipe pressurizing pump is arranged in the described pick-up tube, and described unidirectional bottom valve is arranged on the entry end of pick-up tube.
In a preferred embodiment of the invention, described high suction depth centrifugal pump device also comprises a sealing negative pressure water tank, and described sealing negative pressure water tank is arranged between centrifugal pump inlet and the pick-up tube and with centrifugal pump and pick-up tube sealing and is communicated with.
More preferably, described sealing negative pressure water tank is provided with spout.
Wherein, described pipe pressurizing pump be arranged in the pick-up tube, in six meters of the goal displacement liquid levels tops.
Wherein, described centrifugal pump is arranged in the described pipe pressurizing lift of pump.
High suction depth centrifugal pump device of the present utility model is provided with the pipe pressurizing pump in pick-up tube, entry end in pick-up tube is provided with unidirectional bottom valve, centrifugal pump is arranged in the pipe pressurizing lift of pump, can utilize the pipe pressurizing pump liquid to be transported to the ingress of centrifugal pump like this, by centrifugal pump liquid is detached again, because the end of pick-up tube is provided with unidirectional bottom valve, the liquid in the pick-up tube must flow out because of the reason of High Pressure Difference.The suction journey maximum of the centrifugal pump device of this structure can add the suction journey of centrifugal pump itself for the suction journey of pipe pressurizing pump.Preferably, a sealing negative pressure water tank is set in the ingress of centrifugal pump, can be by the spout on the sealing negative pressure water tank, in sealing negative pressure water tank, fill with liquid, during work, as long as open the just energy on-line operation of pipeline suction booster and centrifugal pump, when opening the centrifugal pump device transfer liquid once more later on, need not in sealing negative pressure water tank, inject liquid again.High suction depth centrifugal pump of the present utility model is inhaled the journey height, other equipment need not be installed again, and construction is simple, and is easy to install and use.
Introduce high suction depth centrifugal pump device of the present utility model in detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is in the preferred embodiment of the present utility model, the structural representation of described high suction depth centrifugal pump device;
Fig. 2 is in another preferred embodiment of the present utility model, the structural representation of described high suction depth centrifugal pump device.
Embodiment
As shown in Figure 1, in a preferred embodiment of the invention, described high suction depth centrifugal pump device comprises centrifugal pump 1, pick-up tube 2, pipe pressurizing pump 3 and unidirectional bottom valve 4, the inlet of described centrifugal pump 1 and pick-up tube 2 are connected, pipe pressurizing pump 3 is arranged in the pick-up tube 2, and described unidirectional bottom valve 4 is arranged on the entry end of pick-up tube 2.Wherein, in 6 meters, described centrifugal pump 1 is arranged within the lift of pipe pressurizing pump 3 described pipe pressurizing pump 3 on the liquid level of target liq 10.
High suction depth centrifugal pump device in this preferred embodiment; during use; open pipeline suction booster 3 earlier, liquid is extracted into the inlet of centrifugal pump 1, and then open centrifugal pump with pipe pressurizing pump 3; when opening this high suction depth centrifugal pump device once more after the shutdown; also need to open earlier pipeline suction booster 3, and then open centrifugal pump, both can carry out drawing liquid work smoothly; during work, pipe pressurizing pump 3 and centrifugal pump 1 are worked simultaneously.The suction journey of described high suction depth centrifugal pump device can reach lift+6 meter of pipe pressurizing pump 3.
As shown in Figure 2, in another preferred embodiment of the present utility model, high suction depth centrifugal pump device of the present utility model comprises centrifugal pump 1, pick-up tube 2, pipe pressurizing pump 3, unidirectional bottom valve 4 and sealing negative pressure water tank 5, the inlet of described centrifugal pump 1 and 5 sealings of sealing negative pressure water tank are communicated with, described sealing negative pressure water tank 5 and pick-up tube 2 sealings are communicated with, pipe pressurizing pump 3 is arranged in the pick-up tube 2, and described unidirectional bottom valve 4 is arranged on the entry end of pick-up tube 2.Wherein, in 6 meters, described centrifugal pump 1 is arranged within the lift of pipe pressurizing pump 3 described pipe pressurizing pump 3 on the liquid level of target liq 10.Wherein, described sealing negative pressure water tank 5 tops also are provided with a spout 6, can inject liquid in sealing negative pressure water tank 5 by described spout 6.
When the high suction depth centrifugal pump device in this preferred embodiment uses, in sealing negative pressure water tank 5, fill with liquid by spout 6 earlier, open pipeline suction booster 3 and centrifugal pump 1 then, just can carry out drawing liquid work.When opening this high suction depth centrifugal pump device once more later on, also only open pipeline suction booster 3 and centrifugal pump 1, just can work smoothly.During work, pipe pressurizing pump 3 and centrifugal pump 1 are worked simultaneously.The suction Cheng Yeke of described high suction depth centrifugal pump device reaches the lift+6 meter height of pipe pressurizing pump 3.
