Abstract

The utility model relates to a flow-expanding pressure-boosting electricity-saving device for a water pump. The technical scheme includes that the device comprises a pressure-boosting chamber, a flow-expanding chamber and an external respiratory chamber, wherein the pressure-boosting chamber and the flow-expanding chamber are connected into a whole and intersected with a main flow pipe, a flow-expanding duct is arranged on the inner wall of the flow-expanding chamber, and the external respiratory chamber is arranged outside the flow-expanding chamber and connected with the flow-expanding chamber. According to the flow-expanding pressure-boosting electricity-saving device for the water pump, the pressure-boosting chamber and the flow-expanding chamber are arranged in the device, instant high pressure at a circulation outlet is used for producing negative pressure in the device, and the produced negative pressure increases flow of a circulating pump under the action of return water pressure of a circulation system so that power of the pump is reduced, and purposes of electrical energy saving and energy consumption reducing are achieved.

Description

Water pump expands the stream supercharging and electricity-saving device

Technical field

The utility model belongs to the fixture of water pump, is specifically related to a kind of expansion stream supercharging device of water pump.

Background technique

Circulating pump system in the closed-system semi-closed work of central air-conditioning system, central heating system and industrial and mining enterprise all needs to keep water circulation.Usually the parameter in the recycle pump is power of motor, lift, flow, bore, wherein flow is directly proportional with refrigeration, area of heat-supply service.The circulation lift of pump mainly is the resistance that overcomes the circulating pump system official website, is keeping in the constant situation of circulating pump system, and lift is higher, and its power of motor of joining is just larger, otherwise then less.The electric energy that the heavy-duty motor that high-lift recycle pump is joined consumes is more, the cost how many direct relations of power consumption move.

Summary of the invention

In order to overcome the deficiency that water pump adapted motor is large, power consumption is high, the purpose of this utility model provides a kind of water pump and expands the stream pressurized machine, and this water pump expands the stream pressurized machine can utilize internal pressure, under the performance that guarantees water pump, reduces the adapted power of motor.

The utility model is by the following technical solutions: water pump expands the stream supercharging and electricity-saving device, comprise the pumping chamber and expand the stream chamber, pumping chamber and expansion stream chamber are connected as a single entity and intersect with main flow pipe, expand the stream chamber interior walls and be provided with the expansion conduit, also comprise outside respiratory chamber, outside respiratory chamber is located to expand to flow outdoor and flow the chamber with expansion and is connected.

When using the utility model, the inlet flange that expands the stream supercharging device is connected with recycle pump; The outlet(discharge) flange that expands the stream pressurized machine is connected with water pipe; The pressure inlet flange of end, pumping chamber is joined and can move with the reflow pipe that leads to heat exchange or chiller plant.When entering the utility model under the effect of system's backwater band hydraulic fluid at recycle pump, it will utilize the instantaneous pressure of loop exit to produce negative pressure in device, the negative pressure that produces improves pump flow under the effect of circulatory system pressure of return water, thereby reduce the power of pump, reach the purpose of using electricity wisely, reduction energy consumption.

According to experiment, using behind the utility model at least can energy-conservation 20%.

The beneficial effects of the utility model are: the utility model expands stream chamber and pumping chamber by arranging, utilize the instantaneous pressure of loop exit in device, to produce negative pressure, the negative pressure that produces improves pump flow under the effect of circulatory system pressure of return water, thereby reduce the power of pump, reach the purpose of using electricity wisely, reduction energy consumption.

Description of drawings

Fig. 1 is the utility model embodiment's structural representation,

Among the figure: 1, circulatory system water outlet flange, 2, expand the stream chamber, 4, the water feeder flange, 5, outside respiratory chamber, 6, the pumping chamber, 7, the pressure inlet flange, 8, recycle pump, 9, water pipe, 10, heat transmission equipment, 11, reflow pipe, 12, the user, 13, supercharging protects the stream pipe.

Embodiment

As shown in the figure, water pump expands the stream supercharging and electricity-saving device, comprises pumping chamber 6 and expands stream chamber 2, pumping chamber 6 and expansion stream chamber 2 are connected as a single entity and intersect with main flow pipe, expansion stream chamber 2 inwalls are provided with the expansion conduit, also comprise outside respiratory chamber 5, and outside respiratory chamber 5 is located to expand outside the stream chamber 2 and with expansion stream chamber 2 and is connected.

During use, be that circulatory system water outlet flange 1 is connected with recycle pump 8 with the inlet flange that expands the stream pressurized machine; The outlet(discharge) flange that expansion is flowed pressurized machine is that water feeder flange 4 is connected with water pipe 9; The pressure inlet flange 7 of 3 ends, pumping chamber is joined and can move with the reflow pipe 11 that leads to heat exchange or chiller plant.When system's backwater band hydraulic fluid enters the utility model under the effect of recycle pump 8, it will utilize the instantaneous pressure of recycle pump 8 outlets to produce negative pressure in device, the negative pressure that produces improves pump flow under the effect of circulatory system pressure of return water, thereby reduce the power of pump, reach the purpose of using electricity wisely, reduction energy consumption.
