Abstract
The utility model belongs to a liquid suction flow pump, comprising a pump casing, a water inlet, a water outlet, a piston and a piston rod. The lower end of the pump casing is provided with the water inlet. The upper part of the pump casing is provided with the water outlet. A place where a middle shaft of the pump casing is positioned is provided with the piston rod whose lower end is provided with the piston. The liquid suction flow pump is characterized in that the water inlet is provided with an inlet valve. The liquid suction flow pump overcomes the defect that other various liquid pumps can not suck flows because air in a cavity can not be excluded when a water source is cut off and no water exists. The liquid suction flow pump can supply for a user on a high floor under pressure. The utility model has the advantages of energy saving, simple structure, small volume, flexible usage, convenient installation, and low cost.
Description
The utility model belongs to a kind of liquid Suction flow pump.
Be to solve the water supply difficult problem of tall building, people often take to low level water pressurization to raise up or mode that high-level reservoir is set solves.But all tall buildings are provided with pumping plant or wet pit, need expend a large amount of human and material resources, and in fact for a certain building, the under-voltage problem that supplies water not is to relate to whole users, and impossible 24 hours continuous waters of each user, and said method is whole building to be pressurizeed continuously or water pumped into flow into the user in the high-level reservoir that is higher than all users again, and this certainly will cause the huge waste of the energy.As from saving the energy, reducing the angle of investing, should water pump be set at each user's water outlet place, make the user can independently control the switch of water.But existing common water pump such as centrifugal pump, gear pump etc., they can only realize the pressurization of low level water is raised up, and can't realize low level water is drawn to a high position, because the negative pressure that gas forms in the cavity of this pump is very little, be not enough to produce the effect of inhaling stream when initial operation.Must reach 10～20Kg and inhale the stream pulling force for high level, therefore, this pump can't satisfy this requirement.
The purpose of this utility model be to provide a kind of can be to the liquid Suction flow pump of the under-voltage water supply of high-rise user.
The utility model is realized by following scheme, Suction flow pump comprises pump case, water intake, water outlet, piston and piston rod, in the pump case lower end water intake is set, on pump case, set out the mouth of a river, the place is provided with a piston rod at the pump case axis, piston-rod lower end is provided with piston, it is characterized in that in the water inlet, establishes an inlet valve.
The utlity model has following advantage:
1, overcome other various liquid body pumps under water source cutout anhydrous state, because of air in the chamber can not be got rid of the defective that can not inhale stream, can be to the under-voltage water supply of high-rise user;
2, owing to be provided with the inlet valve, make the water that is drawn in the pump case be difficult for running off, overcome centrifugal pump, gear pump etc. and had the shortcoming that refluxes, so the efficient height, the energy saved;
3, simple in structure, volume is little, use is flexible, easy for installation, cheap.
Accompanying drawing 1 is Suction flow pump embodiment one a structural representation
Accompanying drawing 2 is Suction flow pump embodiment two a structural representation
1 couple of embodiment one is illustrated below in conjunction with accompanying drawing:
The lower end of pump case ［ 9 ］ is provided with water intake ［ 5 ］, the top of pump case ［ 9 ］ (more than the stroke section of piston) sets out the mouth of a river ［ 3 ］, locate inlet porting valve ［ 4 ］ at water inlet ［ 5 ］, the axis place is provided with piston rod ［ 2 ］ at pump case ［ 9 ］, piston rod ［ 2 ］ lower end is provided with piston ［ 6 ］, one-way cock ［ 7 ］ is set on the piston ［ 6 ］, one water filling hole ［ 1 ］ is set, a wet pit ［ 8 ］ is set on piston on pump case ［ 9 ］ top.
When Suction flow pump is worked, if the residuary waters in the original state pump case ［ 9 ］ all runs off under action of gravity, can pass through water filling hole ［ 1 ］ and inject low amounts of water, these water can be with inlet valve ［ 4 ］ sealing, start motor, pump by transmission device drive piston rod ［ 2 ］ and piston ［ 6 ］, when piston ［ 6 ］ is up, make between piston ［ 6 ］ and the inlet valve ［ 4 ］ and form vacuum, inlet valve ［ 4 ］ is opened naturally, thereby the water that makes lower is drawn to eminence under the barometric pressure effect, and is entered in the pump case ［ 9 ］ by water intake ［ 5 ］, when piston ［ 6 ］ is descending, water is discharged by water outlet ［ 3 ］ by one-way cock ［ 7 ］, and the valve ［ 4 ］ that enters the mouth is simultaneously closed, and makes the unlikely backflow of water in the pump case ［ 9 ］.Along with pumping of piston ［ 6 ］, water just constantly flows out from water outlet ［ 3 ］.Generally, holding in the wet pit ［ 8 ］ when initial has low amounts of water, and after motor started, the water in the wet pit ［ 8 ］ can seal inlet valve ［ 4 ］, thereby can all start to water filling hole ［ 1 ］ water filling at every turn owing to chatter overflows.
2 couples of embodiments two of the present utility model are illustrated below in conjunction with accompanying drawing:
The lower end of pump case ［ 9 ］ sets into the mouth of a river ［ 5 ］, water inlet ［ 5 ］ locates to be provided with an inlet valve ［ 4 ］, set out the mouth of a river ［ 3 ］ in the below of pump case ［ 9 ］ (under the stroke section of piston), water outlet ［ 3 ］ locates to be provided with a water outlet one-way cock ［ 10 ］, the axis place is provided with piston rod ［ 2 ］ at pump case ［ 9 ］, piston rod ［ 2 ］ lower end is provided with piston ［ 6 ］, and wet pit ［ 8 ］ is set on the piston ［ 6 ］, establishes water filling hole ［ 1 ］ on pump case ［ 9 ］ top.Its working principle and embodiment one is big to identical, and when difference was that piston ［ 6 ］ is up, the water outlet one-way cock ［ 10 ］ of water outlet ［ 3 ］ was closed, and piston ［ 6 ］ is when descending, and one-way cock ［ 10 ］ is opened.
