Description

Double-valve siphon water pump

Technical Field

The invention relates to the technical field of water pumps, in particular to a double-valve siphon water lift pump.

Background

The piston of the water lift pump is easy to wear when working for a long time, and is easy to corrode when being soaked in liquid medium. The common piston type water lifting pump drives the piston to move by using a lever principle and manually pressing a handle, thereby wasting time and labor. The blades of the centrifugal water lift pump are core parts, but the blades are easy to generate fatigue fracture under the water pressure impact for a long time. Generally, the existing water pumps face: the problems of water pump aging, blade cavitation abrasion, bearing breakage, large shaft bending, mouth ring damage, pump shell breakage, vibration aggravation and the like can cause serious performance reduction of the water pump. The old water energy pump or hydraulic ram pump has been one hundred years old, because the inefficiency, must have enough water heads, and the noise is big, therefore application range receives certain restriction.

Detailed Description

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

The invention provides a double-valve siphon water pump which comprises a straight pipe 1, a first siphon pipe 3 and a second siphon pipe 4.

The lower end of the straight pipe 1 is inserted into the water source 2, and the upper end of the straight pipe 1 is communicated with the atmospheric environment.

One end of the first siphon 3 is communicated with the straight pipe 1; the other end of the first siphon 3 is connected to the atmosphere.

One end of the second siphon 4 extends into the first siphon 3; the other end of the second siphon 4 is at a lower level and is open to the atmosphere.

The straight pipe 1 is provided with a first check valve 5 and a second check valve 6, and the first check valve 5 and the second check valve 6 are communicated in the same direction and are from bottom to top. The first one-way valve 5 is positioned below the joint of the straight pipe 1 and the first siphon 3; the second one-way valve 6 is positioned above the joint of the straight pipe 1 and the first siphon pipe 3.

And a water filling port 7 is arranged at one end of the first siphon pipe 3, which is far away from the straight pipe 1, and the water filling port 7 is positioned above the second siphon pipe 4.

In the concrete implementation of the present invention, water is first injected into the first siphon tube 3 through the water injection port 7, and air in the first siphon tube 3 and air in the straight tube 1 are discharged from the second check valve 6 by the water injection. When the water level in the first siphon pipe 3 rises to the highest point of the second siphon pipe 4, the second siphon pipe 4 automatically drains water under the action of the siphon principle, and the water in the first siphon pipe 3 is pumped out. As the water discharge progresses, a negative pressure is created in the first siphon tube 3, which acts on the first check valve 5, causing water in the water supply 2 to be drawn into the first siphon tube 3. When the water level drops to the lowest point of the second siphon 4 at the end of the first siphon 3, the water discharge is stopped. The water is again supplied into the first siphon tube 3 through the water supply port 7, the water level in the first siphon tube 3 rises again, and the next cycle of water discharge and water suction is continued. The water in the water source 2 can be pumped up by continuously injecting water to absorb water.
