Abstract
Disclosed is a hand water uptake centrifugal pump for agricultural well. A to-and-fro hand pump is arranged on a centrifugal pump, and the hand pump is communicated with the inner cavity of the centrifugal pump. The inner of a hand pump stand is provided with a unilateral valve. The inner of a hand pump body is provided with a piston, and one end of the piston is connected with a press handle. The press handle is arranged on a bracket. The exit of the centrifugal pump is provided with an exit unilateral valve. The unilateral valve comprises a unilateral valve board and an exit connecting pipe. The connecting pipe is connected with the exit of the centrifugal pump, and the middle is provided with the unilateral valve board. The exit unilateral valve board appears double-circle shape.
Description
The utility model belongs to the water pump that pumping irrigation well is used.
Pumping irrigation well adopts submersible pump and the centrifugal pump of wearing bottom valve to draw water more at present.Submersible pump system is combined into one pump and motor, all places water, the electrical machine insulation difficulty, and inconvenient maintenance, and also price is more expensive, requires the motor-pumped well hole diameter very big simultaneously, and its using scope is restricted.Use general centrifugal pump and draw water, then must be at the fore device bottom valve of suction line.See the general centrifugal pump structure schematic representation of Fig. 2.The method of work of this centrifugal pump is the degassing method of pouring water.Promptly must be from the delivery side of pump exhaust of to pump and suction sleeve, pouring water.This structural requirement motor-pumped well caliber is greater than 3～4 times in water pump suction pipe footpath.The investment of motor-pumped well is higher, and every well is wanted more than 2700 yuan, and the maintenance of bottom valve is quite difficult.
The purpose of this utility model is the shortcoming that overcomes above-mentioned pumping irrigation well water pump, and a kind of hand suction centrifugal pump of new structure is provided.
The purpose of this utility model is achieved in that the bottom valve that removes former centrifugal pump, adorns a reciprocal hand pump at the rear portion of the anterior bend pipe of centrifugal pump, connects by the hand pump seat.Hand pump communicates with the centrifugal pump inner chamber.Be equipped with one-way valve in the hand pump seat, be equipped with piston in the hand pump housing.Piston one end connects a pressure handle, and pressure handle is bearing on the support.Be equipped with an outlet one-way valve on centrifugal delivery side of pump, one-way valve is made of the discharge connection of check valve sheet and centrifugal pump.Discharge connection and centrifugal pump outlet are joined, and the centre accompanies the outlet check valve sheet.The outlet check valve sheet is two gardens annular, and ring top, two gardens is one, and outer garden ring is sealing gasket.Promptly seal.
Back and forth the working principle of hand pump is that the gas in the airtight pipe-line system is discharged, and forms vacuum state, under the atmospheric pressure effect, the motor-pumped well water surface is constantly risen, and reaches the purpose of drawing water.Be about to the former degassing method of pouring water and change into exhaust water-filling method.Add one glass of water slightly to hand pump, move pressure handle drive piston up and down and slide up and down along the hand pump housing.When piston upwards rises, cavity forms vacuum state below the piston, and the pump discharge one-way valve is fastened, and the motor-pumped well water surface rises.Piston is to lower slider, cavity gas is compressed below it, pressure raises and goes out along the gap between the piston and the hand pump housing, gas is discharged from, come and go several times successively, then the gas on water pump suction pipe road is discharged from, and the water surface in the motor-pumped well raises, until being full of whole cavitys, created the condition that centrifugal pump starts.Start Diesel engine pump and promptly draw water this moment.
The utility model has the advantages that simple in structure, the direct insertion machine well casing of centrifugal pump bend pipe struck up partnership to get final product.The suction sleeve that has saved pump, the hole diameter of motor-pumped well can reduce 2/3, and the motor-pumped well cost reduces greatly.Owing to do not adopt bottom valve, whole hand suction centrifugal pump places on the ground, and installation and maintenance are very convenient.The simple easy to perform of the using method of this pump.
The utility model is provided by following examples and accompanying drawing thereof.
