Pumps can be divided into motor pumps and manual pumps according to different driving forces. Motorized pumps are affected by geographical conditions (lack of electric energy, economic difficulties), and their use is greatly restricted. In plateau mountainous areas where water resources are scarce, economical and practical manual pumps can only be used to solve the problem of water for humans and livestock and supplementary watering in drought. the

According to the national standard, the types of manual pumps are divided into two categories: shallow well pumps and deep well pumps. The working parts of shallow well pumps are above the ground and rely on suction to work; the working parts of deep well pumps are below the ground and rely on lift. pump. The most widely used pump is a piston pump that pumps liquid through the reciprocating motion of the piston. the

The shortage of water resources in the world has seriously endangered people's lives. There are still 60% of the arable land in our country belonging to arid and semi-arid areas, and to ensure the development of dry farming in these areas, we can only rely on water conservancy infrastructure such as dry wells, water cellars, and flood ponds to collect rain, and promote new water-saving irrigation methods. Technology to alleviate the water crisis is imperative. The water level in many plateau mountainous areas in our country is astonishingly low, and the depth of water taken from underground wells can reach more than 10 meters, and even 20 meters can not see water. In the arid regions of Africa, however, the primitive and clumsy way of drawing water is still used for draft, and the degree of difficulty is even more conceivable, and there is no mention of the development of agricultural production. the

In order to solve the problems of low groundwater level in the above-mentioned areas, inconvenient drinking water for humans and animals, and difficulty in raising water for irrigation, someone once designed a deep well manual pump, but its structure is heavy and inefficient, and it can only pump water out of the ground, and cannot be raised high and sent far. the

Detailed ways:

A high-pressure duplex deep well submersible manual pump as shown in Figure 1a and Figure 1b, includes a pump body 15 made of engineering plastics, and the inner cavity of the pump body 15 is divided into a high-pressure chamber A and a water outlet by a second check valve 6 Chamber B, one side of the pump body 15 is provided with a high-pressure pipe 5 parallel to it, the bottom end of the high-pressure pipe 5 communicates with the bottom of the piston 4 in the pump body 15, the bottom of the pump body 15 communicates with the high-pressure chamber A through the water inlet pipe 16, and the high-pressure chamber A and water outlet chamber B are communicated by the upper water pipe 7, and the water outlet chamber B is connected with the outlet pipe 13. A third check valve 14 is arranged between them. Every 7 meters from the bottom of the pump body 15, there is a high-pressure pipe 5 and an outlet pipe. A connecting pipe 12 is arranged between 13, and a valve valve 9 is installed at the connection between the connecting pipe 12 and the high-pressure pipe 5, which is used to control the one-way conduction of the circuit; the bottom end of the pump body 15 is provided with a first check valve 3; The bottom of A is provided with a disc-shaped piston 4. The disc-shaped piston 4 has the function of turning on when it goes down, and it is closed when it goes up. The disc-shaped piston 4 is connected with the driving rocker 11 through a steel wire rope 8. The guiding device 17 that limits its movement trajectory is fastened on the inner wall of the pump body 15; the outer wall of the bottom of the pump body 15 is provided with a well wall locking claw plate 1, on which is connected a claw plate adjusting cable 2, which are used for installation Pump; the bottom end of the pump body 15 is provided with a pressure relief device 19, which is used for water discharge in the pump to facilitate disassembly and maintenance; the high pressure pipe 5 of the manual pump, the upper end of the water outlet pipe 13, the claw plate adjustment cable 2 and the rope end of the pressure relief device 19 All are fixed on the well head fixed plate 10. Described water inlet pipe 16, upper water pipe 7, water outlet pipe 13, high-pressure pipe 5, connecting pipe 12 are all corrosion-resistant resin pipes. the

The disc-shaped piston 4 is composed of sealing rubber 20, piston bracket 21, gasket 22, nut 23, screw 24 and disc-shaped rubber valve plate 25, and the peripheral wall of the piston bracket 21 is equipped with sealing rubber 20 for pump The dynamic seal between the body 15 and the disc-shaped piston 4; the disc-shaped rubber valve plate 25 is installed on the piston bracket 21, and it is fixed with the gasket 22, the nut 23 and the screw 24. There is a "V" on the disc-shaped valve plate 25 The groove makes the disc rubber valve plate 25 capable of one-way movement; the piston bracket 21 itself has holes. When the disc-shaped piston 4 moves downward, due to the pressure difference, water will open the disc-shaped rubber valve plate 25 through the hole on the piston bracket 21, and the water will enter the high-pressure chamber A from the bottom of the disc-shaped piston 4. When the disc-shaped piston 4 moves upward , the disc-shaped rubber valve plate 25 returns to its original shape. the

Working process and working principle of the utility model:

Before work, first dive the pump body 15 to an appropriate underwater position, adjust the retraction scale of the well wall locking claw plate 1 through the claw plate adjustment cable 2, so that it expands to the inner wall of the well like a claw anchor, and tightens the utility model. solid. At this point, tighten the jaw plate adjustment cable 2 and fix it on the wellhead fixed plate 10 . Simultaneously, the rope end of the pressure relief device 19 is also tightened and fixed on the wellhead fixed plate 10 . The high-pressure pipe 5 and the water outlet pipe 13 are also fixed on the inlet fixing plate 10 accordingly. the

When the pump body 15 enters the water in a natural state, the disc-shaped piston 4 is at the downward end position, and the natural water pressure will make the check valve 3 open, so that the water naturally enters the bottom of the cylinder body and gradually rises, and enters the high-pressure chamber A through the water inlet pipe 16 , Open check valve 6 again, and upper water pipe 7 also enters water simultaneously, and when being full of outlet chamber B, check valve 14 is opened, reaches stable (about 1 meter away from well water surface) until outlet pipe 13 water levels. At this time, the check valve 3, the check valve 6 and the check valve 14 are closed, and the high-pressure double deep well submersible manual pump is in a waiting state. the

When pressing down, the rocker 11 is driven, and the disc-shaped piston 4 is moved upward through the steel wire rope 8. At the same time, the recovery device 18 is stretched. The volume of the high-pressure chamber A decreases due to the upward movement of the disc-shaped piston 4, and water is sent into the water outlet chamber B through the upper water pipe 7. . After the water outlet chamber B reaches a certain pressure value, the check valve 14 is opened, the water is sent to the water outlet pipe 13, and the water level in the water outlet pipe 13 rises. When the lifting height of the disc-shaped piston 4 reaches the upper limit position, the high-pressure chamber A communicates with the high-pressure pipe 5, and due to the pressure difference, the check valve 3 opens, and water enters the high-pressure chamber A through the water inlet pipe 16 and enters the high-pressure pipe 5 until the high pressure Pipe 5 and outlet pipe 13 internal water levels are equal. At this time, the check valve 3 and the check valve 14 are closed. the

When stop driving the rocking bar 11, by the contraction force of the return device 18, the disc-shaped piston 4 descends. At this time, due to the excessive downward pressure, in order to prevent the piston from "locking", the piston is specially designed as a one-way valve structure. The disc-shaped rubber valve plate 25 on the disc-shaped piston 4 is opened, and the upper and lower chambers are communicated, the disc-shaped piston 4 returns to the original position, and the disc-shaped rubber valve disc 25 is closed. In this cycle, the water level continues to rise. the

When reaching the first connecting pipe 12 (7 meters from the bottom of the pump body 15), the water pressure opens the valve valve 9, and part of the water enters the high-pressure pipe 5, and the rapidly moving water column will form a strong pressure from top to bottom. The bottom of the Ultima-shaped piston 4 produces an upward thrust, which creates a resultant force of lifting force and thrust superimposed, thereby overcoming the gravity pressure of the water column in the water pipe, and reaching the weight of the water in the high-pressure pipe 5, the outlet pipe 13, and the pump body 15. The balance of water pressure achieves the ideal effect of labor saving. The high-pressure duplex deep well submersible manual pump is according to the operating height, and a connecting pipe 12 is every 7 meters away from the bottom of the pump body 15, that is to say, the return water once every 7 meters acts on the bottom of the disc-shaped piston 4 to generate upward thrust. (It is planned that the water needs to be lifted by 60 meters, and a connecting pipe 12 every 7 meters supplements the water column to generate momentum to the high-pressure pipe 5, so the driving of the rocking bar 11 is to save part of the force every 7 meters until the water outlet pipe 13 is discharged, and the driving force reaches a stable value). the

If the high-pressure duplex deep well submersible manual pump needs to be repaired and the wellhead raised, the water in the pump needs to be released to reduce the weight. At this time, lift the flexible end of the pressure relief device 19 to open the check valve 3, and the water in the pump flows out; then loosen the claw plate adjustment cable 2, and the well wall locking claw plate 1 shrinks and the well wall expansion force disappears and is easily reclaimed by the pump. the
