Summary
To use a multi-stage centrifugal blower, we must first learn to start it, because it is basic. However, there are many tricks, if you master it, you can start the machine smoothly, otherwise it will damage the machine. In order to let everyone have the correct operation method, I will introduce it in detail below.
To use a multi-stage centrifugal blower, we must first learn to start it, because it is basic. However, there are many tricks, if you master it, you can start the machine smoothly, otherwise it will damage the machine. In order to let everyone have the correct operation method, I will introduce it in detail below.
1. Before starting the multi-stage centrifugal blower, please contact the monitor and the central control room. Notify plant dispatchers and electricians, instrument personnel and maintenance personnel to arrive on site to notify coke oven risers and basements. Notify the downstream gas operating position.
2. Mapping machine: clean the lower liquid pipe, the suction temperature shall not exceed 70 ℃. In your spare time, please use the outlet steam pipe, steam pipe and lower liquid pipe to pump the machine, and the opening of the door should be small when pumping. The time cannot be too long.
3. During the suction process, the machine must be shaken continuously. Moreover, the condensate produced by the suction machine should be discharged at any time.
4. Turn on the electric heater to make the oil temperature of the fuel tank higher than 25 ℃. Then start the working oil pump to make the oil system run, and check the oil return of the high-level oil tank on behalf of each operation. Water supply and drainage conditions for oil cooler.
5. Position check that the parameters of the operation panel of the variable tilt governor meet the requirements.
In fact, the principle of starting the multi-stage centrifugal blower is the same as the principle of starting the computer. Order is important. Only by studying and mastering correctly can we use the machine better.
