Abstract
A circulating water pump system additionally provided with frequency converters comprises four circulating water tanks, four circulating water pumps and two condensers. The circulating water tanks are communicated with the circulating water pumps; the circulating water pumps are communicated with the condenser; at least one of the four circulating water pumps is provided with one frequency converter; a hydraulic quick closing valve is mounted between each circulating water pump and the corresponding condenser; the four circulating water tanks are communicated together by the aid of a hydraulic valve; the two condensers are communicated together by the aid of a valve; and a valve is mounted between each circulating water pump and the corresponding circulating water tank. One circulating water pump is additionally provided with the frequency converter, so that cooling water flow needed by two steam turbine generator units is adjusted, and the purpose of controlling the condensers in vacuum is achieved by changing the rotation speed of the circulating water pumps so as to change the flow. Economical vacuum is ensured while energy consumption is reduced, the circulating water pump system is simple, effective and quick and obtains long-term returns by the aid of less investment without halting, and frequency converters can be mounted one by one.
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.
