Water pumping method of water pushing pipes and efficient liquid pump using method

Abstract

The invention discloses a water pumping method of water pushing pipes and a liquid pump using the method. The problem of extra power consumption and the problem that a piston pump affects the continuity of liquid flow due to the fact that the direction and the speed of the liquid flow pumped by a centrifugal liquid pump are changed multiple times are solved. According to the method, two pipelines, i.e., the water pushing pipes with one-way valves are used for making reciprocating motion in opposite directions, so that one-way pushing is conducted on the liquid flow; the liquid flow flows in a pump body smoothly, continuously and evenly; the structure is simple; and efficiency is high. A plurality of combinations are applied in a composite mode, a liquid inlet of the previous combination and a liquid outlet of the next combination are connected together, the combinations are connected in series for application, and the method is suitable for a deep oil well pump, a high lift pump, a high pressure pump and the like.

Description

Technical field [0001] The invention belongs to the field of liquid pumps, and specifically relates to a method for pushing water pipes to pump water and a novel high-efficiency liquid pump using the method. technical background [0002] Existing known liquid pumps, such as lift pumps, deep well pumps and booster pumps, generally have impeller type, propeller type, reciprocating type, and extrusion type. The impeller type uses the principle of centrifugal force to throw water to the outside of the impeller, and then forms a high pressure there to press the water out of the pump. The center part of the impeller uses the low pressure formed by centrifugal force to suck in the water outside the pump, and so on. The propeller type also uses the blades to quickly agitate, shear and push the water flow. Every drop of water passing through the pump is from the smooth flow of the inlet pipe, to the complex centrifugal torrent or agitation and extrusion, and then to the smooth flow o...

Problems solved by technology

The impeller type uses the principle of centrifugal force to throw water to the outside of the impeller, and then forms a high pressure there to press the water out of the pump. The center part of the impeller uses the low pressure formed by centrifugal force to suck in the water outside the pump, and so on. The propeller type also uses the blades to quickly agitate, shear and push the water flow. Every drop of water passing through the pump is from the smooth flow of the inlet pipe, to the complex centrifugal torrent or agitation and extrusion, and then to the smooth flow of the outlet pipe. During this process, there may be several small eddies of water flow mixed in, and the pressure of the water flow changes drastically; the piston type uses the reciprocating movement of the piston to continuously change the capacity of the liquid in the cylinder to absorb and push water, and the static cylinder. When the liquid inlet valve is closed, the liquid flow can only stop moving, wasting the kinetic energy of the continuous flow of liquid

These all increase energy consumption and reduce the energy utilization efficiency of the pump; the structure of the extrusion liquid pump is somewhat complicated, and it is difficult to reduce the diameter of the pump to be used in a deep well; there is also an inertia pump, which uses a pipeline with a one-way valve Reciprocating motion pushes the fluid to flow continuously in one direction, but the speed of the continuous flow of the liquid varies greatly, which cannot achieve efficient pumping, and the pressure of the pumped liquid flow is also small
