Abstract
The circulating water pump system additionally provided with the frequency converter comprises a circulating water pool, a circulating water pump and a condenser; the circulating water pond with circulating water pump intercommunication, circulating water pump with the condenser intercommunication, circulating water pump is four, and wherein at least one installs the converter. And a hydraulic quick-closing valve is arranged between the circulating water pump and the condenser. The number of the circulating water pools is four, and the circulating water pools are communicated together through hydraulic valves. The condenser is two to communicate together through the valve. And a valve is arranged between the circulating water pump and the circulating water pool. The utility model discloses install a circulating water pump additional the converter in order to adjust the required cooling water flow of two turbo generator set, change the flow through changing the circulating water pump rotational speed and reach the vacuum purpose of control condenser, both guaranteed economic vacuum and reduce the energy consumption, simple, effective, swift, adopt the relatively less investment to obtain permanent repayment, and need not shut down, one by one installation alright.
Description
Technical field
The utility model relates to field of energy-saving technology, particularly relates to the water circulating pump system that installs frequency converter additional.
Background technology
The steam turbine condenser uses the cooling-tower circulating water cooling system in a large number in the power-generating enterprise, and promptly recirculated water is got back to the cooling tower cooling after condenser comes out, and squeezes into condenser again by water circulating pump then and circulates with this, guarantees that condenser moves under economic vacuum.Yet the variation of vacuum values random groups load, environment temperature and the recirculated water water temperature and the flow thereof of condenser and changing, under load and the lower situation of water temperature, certain as circulating cooling water flow, then unit is not to move under best vacuum, power consumption is increased, and economy reduces on the contrary.If the vacuum running status of wanting circulating water cooling system to be in to stabilize the economy, must guarantee by changing cooling water flow, but required cooling water flow design when water circulating pump is exerted oneself with maximum unit load, so when the unit underrun, water temperature just causes the consequence of cooling water flow surplus when low, increased unnecessary energy resource consumption.
Summary of the invention
The purpose of this utility model is to avoid weak point of the prior art and a kind of water circulating pump system that installs frequency converter additional is provided.
The purpose of this utility model realizes by following technical measures.
Install the water circulating pump system of frequency converter additional, comprise circulating water pool, water circulating pump and condenser; Described circulating water pool is communicated with described water circulating pump, and described water circulating pump is communicated with described condenser, and described water circulating pump is four, and wherein at least one is equipped with frequency converter.
Between described water circulating pump and the described condenser hydraulic pressure fast valve is installed.
Described circulating water pool is four, and is connected together by hydraulic valve.
Described condenser is two, and is connected together by valve.
Between described water circulating pump and the circulating water pool valve is installed.
The utility model is under the prerequisite that guarantees economic vacuum operation of condenser and don't waste resource; install a water circulating pump additional frequency converter to regulate two required cooling water flows of Turbo-generator Set; change the purpose that flow reaches the control condenser vacuum by changing the water circulating pump rotating speed; not only guarantee economic vacuum but also cut down the consumption of energy; simply, effectively, fast; adopt less relatively investment to obtain permanent repayment, and need not shut down, install by platform and just can.
Description of drawings
Utilize accompanying drawing that the utility model is described further, but the content in the accompanying drawing does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of an embodiment of the water circulating pump system that installs frequency converter additional of the present utility model.
Reference numeral:
Circulating water pool 1, water circulating pump 2, condenser 3.
The specific embodiment
The utility model is described in further detail with the following Examples.
An embodiment of the water circulating pump system that installs frequency converter additional of the present utility model comprises circulating water pool 1, water circulating pump 2 and condenser 3 as shown in Figure 1; Described circulating water pool 1 is communicated with described water circulating pump 2, and described water circulating pump 2 is communicated with described condenser 3, and described water circulating pump 2 is four, and wherein at least one is equipped with frequency converter.Between described water circulating pump 2 and the described condenser 3 hydraulic pressure fast valve 4 is installed.Described circulating water pool 1 is four, and is connected together by hydraulic valve.Described condenser 3 is two, and is connected together by valve.Between described water circulating pump 2 and the circulating water pool 1 valve is installed.
Should be noted that at last; above embodiment only is used to the technical solution of the utility model is described but not to the restriction of the utility model protection domain; although the utility model has been done detailed description with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the essence and the scope of technical solutions of the utility model.
