rapid cooling machine


steam turbine cooling machine

rapidly cooling system high-end machine type China cooling machine new
Product description
This device is a special supporting equipment for accelerated cooling with compressed air after the large-capacity turbine is shut down. It uses compressed air to accelerate the shutdown of the steam turbine. After the cooling system is equipped with this device, the initial temperature of the cooling medium-air can be based on the metal temperature level during the shutdown and the different cooling stages in the entire cooling process. Temperature difference and cooling speed can be easily adjusted.
Product Features
It is a new type of air purification device which is based on aerosol mechanics and condensed filtration mechanism to remove dust from compressed air. Oil mist The filtration efficiency of wet purification is less than 99%. Gu Ke desiccated the steam turbine when it was fast cooling. Clean air quality,characteristics of electric heaters;Compressed air electric heaters are made up of multiple heating tubes. Cylinder body Spiral diversion baffle and so on.
The equipment adopts two high-efficiency deoiling filters, which are separated by centrifugation, followed by stainless steel wire mesh, and then through filters with special ultra-fine fibers as the main body.
The heater core takes the form of spiral diversion, and compressed air enters the heater interior for heating. The heater core is heated by rotating flow around the heater core, and each heating part of the heater element can be effectively utilized. The heat transfer effect of the heat pipe is effective.
The heating wire, magnesia powder and other materials of electric heater are made of high quality materials from selected import, which enhance the service life of heating pipe.

Preparation before commision
rapid cooling equipment debugging personnel clear division of labor, on-site control of one person, valve opening two, centralized control room to monitor one person, to maintain smooth communication, timely follow the commander's orders.
the operator of the control cabinet shall be responsible for all the functions of the screen, buttons, switches, system settings, etc., to be understood, proficient, and skilled in the operation of the professional personnel, (see the control panel diagram for more details)
the unit is ready to use the quick cooling device after shutdown, the sliding parameter should be used as far as possible, and the temperature after shutdown should be reduced as much as possible. The first stage metal temperature of the high pressure cylinder and the inlet blade ring temperature of the middle pressure cylinder drop below 400 ℃.
before forced ventilation and cooling, steam turbine high, medium pressure cylinder should be fully drained and completely isolated. Because the drainage discharge is not enough or the system is not strictly isolated, the cold steam and cold water enter into high, the local temperature difference in the middle pressure cylinder is too large, and the temperature drop rate is too large.
Attention Please in coolong process
The absolute expansion, expansion difference, rotor eccentricity, axial displacement and so on should be monitored in the whole process of forced ventilation and cooling.
After putting the steam turbine into quick cooling, it is just beginning to supply gas, adopting small temperature difference and small flow rate as far as possible, then gradually increasing the flow rate, strictly controlling the intake temperature and ventilation volume of the cylinder
In principle every adjustment, stable for 30 minutes, no change or little change, adjust again.
Air heater outlet temperature should be steadily reduced without sudden jump phenomenon, when high, medium pressure cylinder inlet air diversion pipe wall temperature of 100; When the first metal temperature of the high pressure cylinder falls below 200 ℃, the ventilation volume can be increased, the fully open electric regulating valve and the full open high, medium pressure cylinder inlet valve can be increased when the temperature is about 200 ℃.
When the first stage metal wall temperature of the high pressure cylinder and the ring holding temperature of the first static blade of the middle pressure cylinder are below 150 ℃, there is no obvious increase, and the forced ventilation cooling is finished. Close the high, medium pressure cylinder intake valve, and then continue to turn the car for 30 minutes, depending on whether the temperature pick-up or not, if not, can stop the car, start maintenance work.
After all the operation, close the compressed air manual valve and electric regulating valve, open the quick cooling device sewage valve, turn off the power supply, check the equipment for abnormal conditions,facilitate the next normal operation.
