Problems solved by technology

[0004] At present, the pumping of a large amount of liquid, such as pipeline pressurization, water pumping projects, farmland drainage and irrigation, etc., is widely used in centrifugal pumps and paddle pumps. Their advantage is that the flow rate of the liquid flow is uniform and stable, but the liquid flow in the pump When performing pumping work, it needs to be stirred at a high speed by the paddle or the impeller, which will inevitably consume power, which is especially obvious when the speed of the impeller or the paddle does not meet the requirements; the existing known reciprocating pump uses the reciprocating motion of the piston Continuously change the capacity of the liquid in the cylinder to absorb and push water. When the valve on the static cylinder is closed, the liquid flow can only stop moving, wasting the kinetic energy of the continuous flow of the liquid, and this kinetic energy is very large. Inertia The pump uses this kinetic energy to pump water, which proves this
Although the method I announced in the patent application with application number 201510449464.5 solves the above problems, the structure is still too complicated, and there are too many sealing rings in the pump body, which affects the energy utilization efficiency of the pump, increases energy consumption and additional structures cost, the method needs to be improved

Embodiment Construction

[0008] Such as figure 1 , in the cylinder liner of a pump body 1, two sets of hollow plungers or pistons 2 with one-way valves 3 in the same direction are used in series one after the other, and two sets of linear motors 4 act on the power of the two sets with one-way valves 3 respectively. On the hollow plunger or piston 2 of valve 3, make them reciprocate in opposite directions, cooperate with each other, and push the liquid flow in turn to do work. When two sets of hollow plungers or piston 2 with one-way valve 3 are pushed relative , the one-way valve 3 on the front hollow plunger or piston 2 near the water outlet is opened, the one-way valve 3 on the rear hollow plunger or piston 2 is closed, and the fluid is pushed out of the water outlet by the rear hollow plunger or piston 2, such as figure 1 As indicated by the arrow in the figure 2 In the second middle, when the two sets of front hollow plungers or piston 2 are pushed in the opposite direction, the one-way valve 3 ...

Abstract

The invention relates to a double-plug series connection application method of a reciprocating pump, and a high-efficiency liquid pump applying the method, and solves the problems that a conventional reciprocating pump influences the continuity of a liquid flow, and is complex in structure, high in manufacturing cost, a, and heavy. According to the double-plug series connection application method, two sets of hollow plungers or pistons, each of which is provided with a one-way valve, are assembled in a pump cylinder in a series connection manner, and are respectively in reciprocating movement in opposite directions to perform one-way pushing on the liquid flow in turns; and the liquid flow adopts a smooth, continuous and even flowing manner in a pump body. The high-efficiency liquid pump disclosed by the invention is simple in structure and high in efficiency; and a plurality of pumps are in composite application: a liquid inlet of the last pump body is integrally connected with a liquid outlet of the next pump body, the pumps are in series connection for application, and any sets in the pumps can be opened and closed according to the pressure requirement, so that the high-efficiency liquid pump is suitable for a deep oil well pump, a high-lift high-pressure pump and the like.
