Technical field
The present invention relates to water pump Application Areas, particularly relate to the water pump for the circulating water system with high-order interchanger and using method thereof.
Background technology
Interchanger (heatexchanger) is the equipment that the part heat of hot-fluid passes to cold fluid, also known as heat exchanger. Interchanger occupies critical role in chemical industry, oil, power, food and other many industrial production, and its interchanger in Chemical Manufacture can be used as well heater, water cooler, condenser, vaporizer and reboiler etc., is widely used. Water circulating pump is conveyance fluid or the machinery making its supercharging, comprises the machinery of some delivering gas. Its effect supplies water coolant to interchanger, in order to other equipment cooling demand. Water circulating pump be widely used in a large number iron and steel, chemical industry, metallurgy, medicine, etc. highly energy-consuming trade, these industries many times have high-order interchanger, cause the selection of present water pump lift not only to be depended on resistance and the Liquid transfer difference of altitude of pipe network system. Also must make the most high-lift height higher than high-order interchanger of water pump. Cause water pump lift so under many circumstances in actual motion well beyond actual needs, cause a lot of energy dissipations.
Assuming that in setting circulating water system, high-order interchanger height is H1, the pressure difference that circulating water system pipe network needs is H2. Obviously the specified lift (i.e. the lift of water pump top efficiency) of pump selection should select H2 under this condition, but its most high-lift H3 < H1 likely occurs in this model water pump. Now just must select in situation water pump the most high-lift >=water pump of H1 could meet system and normally run, so now the specified lift of water pump usually far exceeds H2, can cause very big energy dissipation under normal operating conditions.
Summary of the invention
The technical problem to be solved in the present invention is that the existing water pump selected with the circulating water system of high-order interchanger that is applied to is owing to needing the height taking into account high-order interchanger to cause its specified lift considerably beyond the pressure difference of circulating water system pipe network needs, cause the waste of a large amount of energy under normal operating conditions, the efficient special energy-saving water pump of a kind of pressure charged for circulating water system and using method thereof are provided for this reason.
The technical scheme of the present invention is: for the efficient special energy-saving water pump of pressure charged of circulating water system, it comprises the pond and the high position interchanger that are become circulating water system by pipeline communication, combined water pump is had access between described pond water-in and high-order interchanger water outlet, described combined water pump comprises the first water pump and the 2nd water pump that are connected in parallel between pond water-in and high-order interchanger water outlet, the first valve is had access between described first water pump and high-order interchanger water outlet, the 2nd valve is had access between described 2nd water pump and high-order interchanger water outlet, connection valve is had access between described first water pump and pond water-in and between the 2nd water pump and the 2nd valve.
For the using method of the efficient special energy-saving water pump of pressure charged of circulating water system, it comprises the following steps: (1), close the first valve, the 2nd valve with being connected valve, open the first water pump and the 2nd water pump makes the water in pond be reached maximum lift by driving; (2), open successively and be connected valve and the first valve so that the maximum lift of the first water pump and the 2nd water pump reaches the maximum lift after superposition and superposition by high-order interchanger, the water in pond can by high-order interchanger and finally return to pond; (3), connection valve and the 2nd water pump is closed successively.
For another kind of using method of the efficient special energy-saving water pump of pressure charged of circulating water system, it comprises the following steps: (1), close the first valve, the 2nd valve with being connected valve, open the first water pump and the 2nd water pump makes the water in pond be reached maximum lift by driving; (2), open successively and be connected valve and the first valve so that the maximum lift of the first water pump and the 2nd water pump reaches the maximum lift after superposition and superposition by high-order interchanger, the water in pond can by high-order interchanger and finally return to pond; (3), open the 2nd valve, then close the first valve, connection valve and the first water pump successively.
When the invention has the beneficial effects as follows by adopting series system to solve primary starting the appropriate design of water pump system, the maximum lift of water pump cannot meet the problem of the requirement for height of high-order interchanger, make when pump selection without the need to considering the height of high-order interchanger, only need to consider the pressure difference that circulating water system pipe network needs, reduce the requirement to pump head, thus reduce energy consumption and improve production efficiency, provide cost savings.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, the present invention is comprised and is connected into the pond 1 of circulating water system and high-order interchanger 7 by pipeline 8, combined water pump is had access between described pond water-in and high-order interchanger water outlet, described combined water pump comprises the first water pump 3 and the 2nd water pump 2 that are connected in parallel between pond water-in and high-order interchanger water outlet, the first valve 4 is had access between described first water pump and high-order interchanger water outlet, the 2nd valve 6 is had access between described 2nd water pump and high-order interchanger water outlet, have access between described first water pump and pond water-in and between the 2nd water pump and the 2nd valve and it is connected valve 5.
Only need to meeting the pressure difference of circulating water system pipe network needs when the first water pump and the 2nd pump suction sump, the water outlet in pond is connected by the water-in of pipeline with high-order interchanger, and the water outlet of high-order interchanger is connected with pond water-in by combined water pump.
Using method for the pressure charged efficient special energy-saving water pump of circulating water system is as follows:
