Embodiment Construction

[0008] In the cooling water system of the present invention, the cooling water adopts condensed water or deoxygenated water, and the cooling water with higher temperature is pressurized into the chiller (3) through the cold water pump (1), and the check valve (2) ensures that the cooling water does not flow back , the cooling water transfers heat in the chiller (3) and turns it into cold water at 7~20°C, and the cooling water with a lower temperature enters the air cooler (5), and the oil cooler (7) will enter the air cooler (5) The heat of the air and the oil entering the oil cooler (7) is taken away, the temperature of the cooling water rises, and the cooling water is re-sucked by the cooling water pump (1), so that the closed circuit operation ensures that the temperature of the oil and the temperature of the air are within the specified range It meets the requirements of the cooling of the oil supply system of the steam turbine and the ventilation and cooling system of the ...

Abstract

A water saving method is applied on the steam turbine set and the oil supply cooling system of the steam turbine and the cooling and entilation system of the engine in the power plant. The closed cooling system is comprised of the air cooler, oil cooler, water cooler group, colling pump, the coolant applies pure water, the coolant takes off the heat from the oil cooler and air cooler and temp raised, being pressurized through the cooling pump, the water enters the water cooling group where the heat is transferred and became temperate wtaer, circulating closely, running through the oil cooler, air cooler to meet the need of the cooling system for the steam turbine.

Description

technical field [0001] The invention is applied to the cooling of the oil supply system of the steam turbine and the ventilation cooling system of the generator in the power plant, and can also be used for the bearing cooling of the general rotating equipment. Background technique [0002] The steam turbine oil supply system takes away the heat generated by the friction between the bearing and the bearing bush and the heat transmitted by the steam turbine rotor. In order to ensure the safe operation of the steam turbine, the oil supply system must keep the inlet oil temperature of each bearing of the steam turbine between 35~45℃ During the period, the outlet temperature does not exceed 65°C. Generally, in the oil supply system of a steam turbine, more than two oil coolers (hereinafter referred to as oil coolers) are often installed, which can not only ensure the cooling effect, but also carry out rotation maintenance; The oiler is a surface heat exchanger, the oil flows outs...
