Description
Technical field
The invention belongs to field of generating equipment, particularly relate to a kind of generator unit cooling water pipe structure.
Background technique
The cooling water source of the condenser vacuum pump of conventional power generating equipment has two-way: a road is circulating water, and its water source is the water in cooling tower great Chi; Another road is that open type make-up pump supplies water, and its water source is the water in industrial pond.When summer, ambient temperature is high, thus cause circulating water temperature to raise, cause the cooling effect of vacuum pump poor, vacuum pump suction capactity weakens, and condenser vapour degree of vacuum reduces, and reduces the Economy of unit, if breakdown formula make-up pump is separately for vacuum pump provides cooling water, can increases power consumption and reduce unit economy, equipment runs and repair and maintenance expense, maintenance and the increase of operation maintenance workload simultaneously.
Summary of the invention
For above technical problem, the invention provides a kind of generator unit cooling water pipe structure.
The present invention is achieved by the following technical solutions:
A kind of generator unit cooling water pipe structure, comprise 1. number open type make-up pump, 2. number open type make-up pump, 3. number open type make-up pump, 1. number frequency conversion cooling waterpump, 2. number frequency conversion cooling waterpump and 3. number frequency conversion cooling waterpump, wherein 1. number open type make-up pump and 2. number open type make-up pump are in parallel and with 1 by pipeline, female pipe of No. 2 units connects, 2. number open type make-up pump and 3. number open type make-up pump are in parallel and with 3 by pipeline, female pipe of No. 4 units connects, 1. number open type make-up pump, 2. there is hand operated door in the outlet port of number open type make-up pump and 3. number open type make-up pump, 1. number frequency conversion cooling waterpump, 2. number frequency conversion cooling waterpump and 3. number frequency conversion cooling waterpump are in parallel and be connected with the female pipe of frequency conversion condenser by pipeline, 1. number frequency conversion cooling waterpump, 2. there is hand operated door in the outlet port of number frequency conversion cooling waterpump and 3. number frequency conversion cooling waterpump, it is characterized in that: also comprise bus pipe in parallel, its one end is connected to 1. number frequency conversion cooling waterpump by three branch roads, 2. number frequency conversion cooling waterpump and 3. number between frequency conversion cooling waterpump and its hand operated door, article three, branch road there is respectively 1. number branch road hand operated door, 2. number branch road hand operated door, 3. number branch road hand operated door, the other end connects mother's pipe of 1, No. 2 unit and mother's pipe of 3, No. 4 units.
Further, described bus pipe in parallel also has 1. number master valve and 2. number master valve.
Beneficial effect of the present invention is: because vacuum pump cooling water water consumption is little, as long as the frequency conversion cooling waterpump of a small flow can meet vacuum pump run cooling water inflow, so the water of part frequency conversion cooling waterpump is referred on mother's pipe of 1, No. 2 unit and female pipe of 3, No. 4 units by bus pipe in parallel, solving unit because of circulating water temperature raises, cause the cooling effect of vacuum pump poor, vacuum pump suction capactity weakens, and condenser vapour degree of vacuum reduces, and reduces the defect of its Economy.And frequency conversion cooling waterpump more can saving power than open type make-up pump, therefore the present invention both can save station service, the degree of vacuum of unit can be improved again, thus improve the Economy of unit operation, simultaneously by arranging gate or hand operated door on bus pipe in parallel and its branch road, make, when not stopping unit work, can overhaul.
