Abstract

The utility model relates to the field of non-negative pressure water pumps, in particular to a non-negative pressure energy saving water pump. The non-negative pressure energy saving water pump comprises a water pump body. A water inlet is formed in the left side end of the bottom of the water pump body, and a water outlet is formed in the right side end of the bottom of the water pump body. The non-negative pressure energy saving water pump further comprises a pressure instrument device, a water inlet magnetic valve and a liquid level sensor. The pressure instrument device and the water inlet magnetic valve are arranged on the water inlet from outside to inside. The liquid level sensor is arranged at one side of the top of the water pump body. The non-negative pressure energy saving water pump protects the non-negative pressure water pump against immoderate and frequent start and stop along with pressure of pipe network pipelines, prolongs the service life of the non-negative pressure water pump, reduces maintenance cost and saves energy and is economical and environment-friendly.

Description

A kind of no negative pressure energy-saving water pump
Technical field
The utility model relates to no negative pressure water pump field, is specifically related to a kind of no negative pressure energy-saving water pump.
Background technique
Present tall building or some hotel units, when the peak period that the pipe of city planting ductwork is pressed in water supply reduces, may occur not having the phenomenon that tap water is supplied with, general solution is to adopt will not have the negative pressure water pump and be arranged in the pot with no negative pressure, be arranged on non-negative pressure valve at the pot with no negative pressure top, when pipe network pipeline pressure is not enough, just in time start the supply that water pump guarantees tap water; But when enterprise or individual when not needing to make water, during the ductwork pressure frequent variations, no negative pressure water pump also will be followed startup or be stopped, and has just formed waste, uneconomically also wastes energy.
The model utility content
The purpose of this utility model is at the defective of prior art and deficiency; provide a kind of simple in structure; reasonable in design; a kind of no negative pressure energy-saving water pump easy to use; it adopts no negative pressure water pump top that level sensor is set; on the water intake of no negative pressure water pump, set gradually pressure test device and water intake magnet valve from outside to inside; control the unlatching of water intake magnet valve by the control gear of built-in PLC; thereby the unlatching of control water pump; it is simple to operate; rational in infrastructure; can rational and effective start no negative pressure water pump unlatching and stop; it has the immoderate frequent start-stop that the no negative pressure water pump of protection is not followed pipe network pipeline pressure, has prolonged the working life of no negative pressure water pump, has reduced maintenance cost; saved the energy, not only economy but also environmental protection.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of no negative pressure energy-saving water pump described in the utility model comprises water pump body, and described water pump body bottom, left side is provided with water intake; Described water pump body bottom right-hand end is provided with water outlet; It also comprises pressure tool device, water intake magnet valve and level sensor, and described pressure tool device and water intake magnet valve are arranged on the water intake from outside to inside; Described level sensor is arranged on water pump body top one side.
Further, described water intake magnet valve is anti-water solenoid valve.
After adopting said structure; the utility model beneficial effect is: the utility model it adopt no negative pressure water pump top that level sensor is set; on the water intake of no negative pressure water pump, set gradually pressure test device and water intake magnet valve from outside to inside; control the unlatching of water intake magnet valve by the control gear of built-in PLC; thereby the unlatching of control water pump; it is simple to operate; rational in infrastructure; can rational and effective start no negative pressure water pump unlatching and stop; it has the immoderate frequent start-stop that the no negative pressure water pump of protection is not followed pipe network pipeline pressure, has prolonged the working life of no negative pressure water pump, has reduced maintenance cost; saved the energy, not only economy but also environmental protection.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Description of reference numerals:
1, water pump body; 2, water outlet; 3, water intake; 4, pressure tool device;
5, water intake magnet valve; 6, water proof wire; 7, control gear; 8, level sensor.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of no negative pressure energy-saving water pump described in the utility model comprises water pump body 1, and described water pump body 1 bottom, left side is provided with water intake 3; Described water pump body 1 bottom right-hand end is provided with water outlet 2; It also comprises pressure tool device 4, water intake magnet valve 5 and level sensor 8, and described pressure tool device 4 and water intake magnet valve 5 are arranged on the water intake 3 from outside to inside; Described level sensor 8 is arranged on water pump body 1 top one side.
As another kind of optimal way of the present utility model, described water intake magnet valve 5 is anti-water solenoid valve.
Pressure tool device 4 in the utility model, water intake magnet valve 5 and level sensor 8 link to each other with control gear 7 by water proof wire 6 respectively, are provided with the PLC controller in the described control gear 7; Water intake 3 of the present utility model connects the city planting ductwork entrance, water outlet 2 connects the household tap water pipeline, in use, come the parameter of setting pressure apparatus 4 by control gear 7 built-in PLC controllers, the start and stop that make water pump body 1 not change with the pipeline pressure of city planting ductwork and do not stop, thereby can prolong the working life of water pump, also reduce the loss of electric energy, and reduce maintenance cost.
The utility model it adopt no negative pressure water pump top that level sensor is set, on the water intake of no negative pressure water pump, set gradually pressure test device and water intake magnet valve from outside to inside, control the unlatching of water intake magnet valve by the control gear of built-in PLC, thereby the unlatching of control water pump, it is simple to operate, rational in infrastructure, can rational and effective start no negative pressure water pump unlatching and stop.
It has the immoderate frequent start-stop that the no negative pressure water pump of protection is not followed pipe network pipeline pressure the utility model, has prolonged the working life of no negative pressure water pump, has reduced maintenance cost, has saved the energy, not only economy but also environmental protection.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
