Abstract

The utility model provides an energy-saving water delivery device of a heating plant. The energy-saving water delivery device of the heating plant comprises a water delivery pipe, a circulating water pump and a make-up pump. The water delivery pipe in the heating system is connected with all components. The components comprise a heat exchanger, a filter, the circulating water pump and the make-up pump. The water delivery pipe comprises a primary water supply delivery pipe and a secondary water supply delivery pipe. The circulating water pump is connected with the primary water supply delivery pipe and the secondary water supply delivery pipe. The filter is arranged between the circulating water pump and the make-up pump of a make-up tank. The energy-saving water delivery device of the heating plant is characterized in that the circulating water pump is in parallel connection with a spare circulating water pump. The energy-saving water delivery device of the heating plant has the advantages that when the make-up water amount reaches a certain degree, the circulating water pump and the spare circulating water pump are used for reducing energy consumption to a large extent, so that water supply efficiency is improved, and electricity can be saved as much as 30% compared with that of the prior art when only one pump is used for supplying water.

Description

The energy-conservation water delivery device of a kind of heating plant
Technical field
The utility model belongs to heating plant water-delivery pump field, especially relates to the energy-conservation water delivery device of a kind of heating plant.
Background technology
In existing heating plant equipment, recirculated water need to rely on water pump to drive it and move in system, and existing heating plant is long-term uses the recirculated water in a water circulating pump drive system to flow.When quantity of circulating water increased to a certain degree, the power consumption of water pump increased, and loss of energy is large, reduced the service life of water pump and easily damaged.
Summary of the invention
Problem to be solved in the utility model is to provide the energy-conservation water delivery device of a kind of heating plant, is that large-scale heating plant is saved the energy when especially being fit to the heat supply peak.
for solving the problems of the technologies described above, the technical solution adopted in the utility model is: the energy-conservation water delivery device of a kind of heating plant, comprise water-supply-pipe, water circulating pump and small pump, described water-supply-pipe connects each assembly in heating system, described assembly comprises heat exchanger, filter and described water circulating pump and small pump, described water-supply-pipe comprises once supply water water-supply-pipe and secondary water-supply water-supply-pipe, described water circulating pump connects once supply water water-supply-pipe and secondary water-supply water-supply-pipe, described filter is arranged between the small pump of described water circulating pump and described water supply tank, standby water circulating pump in parallel on described water circulating pump.
Further, standby small pump in parallel on described small pump.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, when rate of water make-up acquires a certain degree, use for, standby two water pumps and can reduce significantly energy consumption, water application efficiency is improved, power saving the most nearly 30% when originally only using a water pump to supply water.

3 ', standby small pump
The specific embodiment
as Fig. 1, shown in Figure 2, the utility model is the energy-conservation water delivery device of a kind of heating plant, comprise water-supply-pipe, water circulating pump 2 and small pump 3, described water-supply-pipe connects each assembly in heating system, described assembly comprises heat exchanger 1, filter 5 and described water circulating pump 2 and small pump 3, described water-supply-pipe comprises once supply water water-supply-pipe and secondary water-supply water-supply-pipe, described water circulating pump connects once supply water water-supply-pipe and secondary water-supply water-supply-pipe, described filter is arranged between the small pump of described water circulating pump and described water supply tank 4, standby water circulating pump 2 ' in parallel on described water circulating pump.
Standby small pump 3 ' in parallel on described small pump.
The course of work of this example: take certain heating plant as example, water circulating pump metered flow 400m 3/ h, lift 37m, power 75kw, water delivery caliber 300mm, specified water yield 370t.When flow reach metered flow 80% the time, namely start standby water circulating pump, for, standby two water circulating pumps are parallel works simultaneously, comparablely only use the power saving of a water supply water circulating pump to reach 30%.Same method also is used for small pump, can save energy consumption equally.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., within all should still belonging to patent covering scope of the present utility model.
