Abstract

The utility model relates to a high lift water pump for deep well whose driving gear is arranged on the ground, comprising a pumping equipment and an ejectisome connected with the pumping equipment. The inlet tube of the pumping equipment pumps the water because of the negative-pressure, while the ejectisome of the device generates the high-speed jet at work, and then the high suction lift water operation for deep well is realized. The suction lift of the device can reach 40 meters, and the total lift can reach 80 meters. The utility model has the advantages of simple device, low cost, high reliability, reasonable structure, convenient arrangement, repairing and maintaining, no rotary part and few fault. The lift water operation for deep well of the suction lift within the 40 meters can be realized, as long as an ejectisome is arranged on the existing pumping equipment.

Description

Deep-well high suction depth picotan

The utility model belongs to picotan, particularly promotes the device of liquid from depths very, and its driving mechanism is positioned at ground.

Along with the surge of industry and urban water consumption, level of ground water is in obvious decline at present, and the water degree of difficulty in inland, plateau section and coastal location has caused people's common concern.Many areas adopt deep-well pump, borehole shaft drivenpump and Submerged Motor Pumps to solve the water lift problem of deep-well more than 10 meters.Yet, because it is too high to be suitable for the cost of these water lift equipment of deep-well use own, the inconvenience of installation, maintenance and maintenance, renewal part or the like reason, for example: deep-well pump, borehole shaft drivenpump mainly adopt multi-stage impeller to constitute, realize the water lift operation, this all brings very big difficulty for installation and maintenance, and the one-level impeller is out of order often, and all underground components all will hang out maintenance; Though and Submerged Motor Pumps is to have only the operation that pulls the plug of single electric pump, the motor manufacture difficulty is big, and is strict to foundry goods, just in case mechanical sealing element is impaired, very easily causes burning out of motor, dangerous.So the state of the art of these deep-well picotans illustrates that all exploitation is a kind of cheap, installing and keep in repair all easily, deep-well high suction depth picotan is undoubtedly very necessary.

The utility model task provides a kind of deep-well high suction depth picotan that can overcome above-mentioned existing deep-well water lift equipment existence deficiency, and it is simple and reasonable for structure, and is with low cost, and it is all extremely convenient to install and keep in repair.

According to the task that the utility model provides, inventor's solution is to realize by the ejectisome that fuses with it that pumping equipment and attaching thereof.Ejectisome one end is connected in the intake pipe of pumping equipment, simultaneously above nozzle, there is a mixing chamber diffusing tube to be connected with riser pipe, picotan by such solution formation, during work, when ejectisome produces high-speed jet, below ejectisome and intake pipe joint, will form negative pressure (vacuum) district, impel well water to suck intake pipe continually, finish the operation of deep-well water lift.Compared with prior art, the utlity model has following advantage: 1, simple and reasonable for structure, as long as utilize ejectisome of original easy pumping equipment attaching can realize 40 meters water lift operations with interior deep-well.Simultaneously, installation and maintenance are all extremely convenient; 2, work safety, good reliability.Ejectisome does not partly have rotary member, easy break-down not, long working life; 3, the ejectisome part can be made of galvanized pipe and ironcasting, and cost is significantly less than existing water lift equipment such as deep-well pump, borehole shaft drivenpump, Submerged Motor Pumps; 4, the utility model suction degree of depth height is inhaled journey and can be reached 40 meters, and total head has 80 meters, and price performance is preferable.

Further describe the utility model below in conjunction with drawings and Examples.

Fig. 1 is the utility model general assembly schematic representation,

Fig. 2 is the sectional view of the utility model ejectisome structure.

With reference to accompanying drawing, the utility model structure is made of the two large divisions, and the one, pumping equipment (1), the 2nd, the ejectisome (2) that fuses with pumping equipment.

Above-mentioned pumping equipment (1) is universal, and its formation comprises power engine (11), centrifugal pump (12), intake pipe (13), riser pipe (14), outlet pipe (15), be in the bottom valve (16) in the water body, feed valve (17), outlet pipe (15) is connected with user's wet pit (18).

Above-mentioned ejectisome (2) comprises three-way pipe (21), pressure supply water pipe (22), water filling hole (23), nozzle (24), and nozzle (24) stretches into the mixing chamber (25) that intake pipe (13) forms and mixing chamber diffusing tube (26) composition diffusing tube (26) shape that is connected in mixing chamber (25) top as shown in Figure 2.One end of ejectisome (2) is connected between the feed valve (17) of pumping equipment (1) and the centrifugal pump (12) on the pipeline by three-way pipe (21), the other end of ejectisome (2) is connected on by mixing chamber (25) and mixing chamber diffusing tube (26) between the intake pipe (13) and riser pipe (14) of pumping equipment (1), and pressure supply water pipe (23) top has water filling hole (22).

The utility model is to realize the operation of deep-well water lift like this: after this device installs, close feed valve (17), toward water filling hole (22) water filling, after centrifugal pump (12) and ejectisome (2), pressure supply water pipe (23) are all filled water, open feed valve (17), start power engine (11), water body is subjected to centrifugal pump (12) impeller turning effort, the current that form are refluxed along pressure supply water pipe (23) by three-way pipe (21) and eject from nozzle (24), form high-speed jet.Meanwhile, just form a negative pressure (vacuum) zone in ejectisome (2) and below, intake pipe (13) joint, well water is drawn into mixing chamber (25) by intake pipe (13) rapidly, and brought into mixing chamber diffusing tube (26) by the liquid stream of high speed operation, in diffusing tube (26) because the turbulent fluctuation effect of fluid molecule, the flow velocity of the liquid stream of high speed operation is gradually consistent with the flow velocity of intake flow, after two strands of liquid streams converge, enter centrifugal pump (12) along riser pipe (14), under the impeller action of rotation, liquid stream is divided into two-way when sending to three-way pipe (21), one is gone into pressure supply water pipe (23) circulation and works on, and another strand then delivered to user's wet pit (18) through feed valve (17)., go round and begin again like this, realized the operation of deep-well water lift.

According to the deep-well high suction depth picotan that the utility model constitutes, it inhales journey can reach 40 meters, and total head has 80 meters, can be widely used in 40 meters water lift operations with interior deep-well, if, adopt resistant material to make, also can be used to realize the water lift operation of hot spring hot water.
