Abstract
The utility model discloses a deep well pump device of a dropping in well type. A fixed frame is arranged on a well head, a water outlet pipe of from 6 to 10 m long is arranged at a water outlet at the upper end of a centrifugal pump, the upper end of the water outlet pipe is fixed on the frame by a Haff clip, so that the centrifugal pump can be hung in a deep well; a power machine which is arranged at one end of the frame is connected with a water pump wheel through a belt. The device changes the mounting and connecting modes of traditional deep well pumps, and the suction lift can be improved by from 2 to 3 times, so that the problem of deep well lifting irrigation in the northern areas and hilly countries of China can be solved.
Description
The utility model relates to a kind of irrigation rig of deep-well water lift.
Because the phreatic yield of China increases year by year, the rate of descent of level of ground water also strengthens year by year, it is also more and more urgent that northern China adopts the task of deep-well irrigation on the field irrigation problem thus, the deep-well irrigation machinery that present China mainly adopts has two kinds, a kind of is borehole shaft drivenpump, and another kind is a submersible pump.The former requires the aboveground related investment of every mouthful of well bigger, installs and removes stage makeup and costume very inconveniently, and the latter then requires well-irrigated area must be equipped with electric power facility.
The purpose of this utility model provides a kind of use, easy for installation, the less falling well type deep-well pump of investment, to solve the problem that northern China farmland deep-well is irrigated.
For achieving the above object, scheme of the present utility model is made up of centrifugal pump, outlet pipe, frame, power engine, its structural feature is for being provided with a fixed frame on well head, the outlet pipe of centrifugal pump is installed with 6-10 rice steel pipe or iron pipe, the upper end is fixed on outlet pipe on the frame by the Hough folder, and the lower end is installed on the water outlet of centrifugal pump, makes centrifugal pump be suspended in the down-hole, power engine is installed in an end of well head frame, by belt with transmission of power feed water pump belt pulley.
The utility model has the advantages that novelly, rational in infrastructure, volume is little, little investment, and the efficient height, easy to install, owing to having adopted vertical installation to overcome horizontally-mounted resonance phenomenon.Therefore prolonged the working life of unit greatly, and original suction journey by 6-8 rice, bring up to 10-18 rice, reduced energy consumption, and reduced cost of production.
Be described further below in conjunction with accompanying drawing:
Fig. 1 is a falling well type deep-well pump scheme of installation
Fig. 2 is a falling well type centrifugal pump cut-away view
Among Fig. 1, frame 3 is arranged on the well head, outlet pipe 5 lower ends are installed on the water outlet of centrifugal pump 1, the upper end is fixed on the frame with Hough folder 4, and power engine 2 is installed in the right side of frame, and power engine is provided with belt pulley 6, water pump pulley is equipped with on the right side of centrifugal pump, power engine belt pulley 6 is given the centrifugal pump belt pulley by vee belt 7 with transmission of power, and the left end of centrifugal pump is provided with intake pipe 8, and the lower end of intake pipe is provided with bottom valve 9.
Centrifugal pump shown in Figure 2 is that the front end at the pump housing 14 is equipped with bearing support 13, and pump shaft 10 is housed in the bearing support, and the front end of pump shaft is equipped with belt pulley 11, and water pump vane 15 is equipped with in the rear end, and bearing door closure 12 is equipped with in the front side of bearing support, and intake pipe 16 is equipped with in the rear end of the pump housing.
Adopt the centrifugal pump of the various models that this device installs and uses, jib-length all shortens, and scope is 210-580mm, and need not footing when installing.
Use on the diesel machine as supporting, water pump vane is to be rotated counterclockwise.
During work, power engine 2 passes through belt 7 with transmission of power feed water pump belt pulley 11, belt pulley is passed to impeller 15 to power by pump shaft 10, the rotation of impeller 15 makes and forms vacuum in the water pump cavity, make the interior formation of well water and water pump body cavity pressure poor, at this moment well water is just by outside bottom valve 9, intake pipe 8 and outlet pipe 5 out wells.
