Abstract

The utility model discloses an energy saving device for deep well pump. The energy saving device for deep well pump is characterized in that: the inner side of the well barrel is provided with soft pipes, and the outer side of the lift pipe of the water pump is provided with a pressure bladder. Because the bladder makes the well barrel divided into an upper well barrel and an airtight lower well barrel and the airtight lower well barrel is pumped as negative pressure by a vacuum tube, the well can have higher water level by using the double actions of the ground-water pressure difference and the negative pressure in the well. Besides, the depth that the water pump is placed in the water is reduced, the length of the lift pipe is shortened, and the lift of water pump is reduced. Therefore, the consumption of the power of motor is reduced, and the purposes of energy-saving, consumption reduction and material saving are achieved.

Description

The deep-well pump energy saving device

One, affiliated field: the utility model relates to a kind of deep-well pump energy saving device.

Two, background technique: mostly existing deep-well pump lifting pipe is to be connected to more than the ground from the down-hole water surface with steel pipe, because the water surface when drawing water in the pit shaft will descend, the pump head of water pump will be placed into below the dynamic water level (the continuous proper functioning of water pump and down-hole drawdown up to stable water level).Water pump will be transferred to deep position like this, and it is many to consume steel, and the mounting cost height has increased the lift of water pump simultaneously, and power consumption increases.

Three, summary of the invention: the utility model provides a kind of dismounting more convenient, makes the deep well water pump setting depth little, thereby saves tubing, reduces cost and reduces the deep-well pump energy saving device of energy consumption.The technological scheme that this deep-well pump energy saving device adopts is: at shaft in wall lining one deck flexible pipe, flexible pipe is fixed by well lid and rubber pad, the lifting pipe of the water pump in pit shaft exceeds the water surface site outside and is with a pressure bladder, it is by upper and lower two clamping plate constrain heights, vacuum tube and water pump elastic cable paper pass from two sleeve pipes, and sleeve pipe has upper and lower four seal rings that two sleeve pipe two-port are sealed.

This deep-well pump energy saving device is divided into pit shaft and airtight well-sinking with pit shaft, with exhaust tube and well-sinking UNICOM, extract the well-sinking air out, make well-sinking form vacuum, the well water face is improved, this just makes deep-well pump not need to be installed to very dark position, thereby has saved steel pipe, has reduced cost.Water level does not descend simultaneously, has shortened the lift of water pump and has saved the electric energy that draws water again.

Four, accompanying drawing 1 is that the deep-well pump energy saving device is installed schematic diagram.

Five, specific embodiment: the examples of implementation that further specify the deep-well energy saving device below in conjunction with accompanying drawing.At first at shaft in wall (a 6) cover lining flexible pipe (4), it reaches downwards below the water surface, and preventing has gas to enter from well bore wall.Flexible pipe extends upwardly to well head, and is fixing by well lid (2) and rubber pad (3).In the pit shaft that has served as a contrast flexible pipe (4), put into deep-well pump (12) in the lifting pipe outside, the deep-well pump energy saving device is installed in the above position of the water surface, this device is a pressure bladder (15), have punch holder (16) and die holder (9) to be fixed on the lifting pipe outside respectively at the air bag upper and lower faces, the restriction air bag increases up and down.When the gas tube (5) of air bag by stretching to well head when using air-pump inflating, air bag can only be expanded to substantially horizontal, thereby has sealed the space between pit shaft and lifting pipe (1).Establish in upper and lower baffle plate (16) and (9) and to fill vacuum tube sleeve pipe (8) and elastic cable paper sleeve pipe (14), vacuum tube (11) and water pump elastic cable paper pass thus, the two-port of two sleeve pipes (8) and (14) is sealed in four seal rings (7), (10), (13), (17), so just forms airtight well-sinking.

The starting mode of pump that at every turn draws water is preceding takes the interior air of well-sinking (19) with vacuum pump away by the drawing-off mouth (20) of vacuum tube (11) earlier, makes well-sinking form negative pressure, and water level is improved.Therefore reduce the degree of depth in the water pump placement well, shortened lifting pipe length, reduced the water outlet lift, reduced power of motor consumption, having reached the energy-saving and cost-reducing purpose of economizing material.

Earlier at the lifting pipe of water pump, load onto the pressure bladder and the upper and lower clamping plate that are fit to size during use, again the vacuum tube elastic cable paper is passed from sleeve pipe and will overlap effective seal ring and seal, outside vacuum tube, airbag inflation pipe exit well; On the well bore wall lining, manage, at last deep-well pump energy saving device and lifting pipe one are lifted in the pit shaft, air bag is charged to preset air pressure, shut the space between pit shaft and the lifting pipe, can begin to prepare to draw water.

Change the size of well lid, pressure bladder and upper and lower clamping plate, the deep-well pump energy saving device is applicable to the well of various calibers.
