1. In the starting state, cutting magnetic lines will also appear when the rotor rotates (the generator rotor is a coil), so it will also generate heat, especially local heat, which needs to be cooled.
2. When the starter performs logic, the operation of the internal cooling water pump is a logical condition, which is also based on the first condition. It is similar to the need to start lubricating oil. oil pump and the lift oil pump when starting the starter. When sealing the oil pump, you are worried about damaging the journal, bushing and sealing pad.
How to add bushings when rotating the hydraulic turbine generator
Tightening 1 plays a sealing role and tightening 2 plays a fixing role. You need to tighten 1 first, then 2. If 2 is tightened first, there will be a traction when tightening by 1, which will change the degree of compression of the joint. 2. Compared to removing the pin, installing the electric pin is more complicated. You need to follow the steps to complete it step by step. 1. Coat the new pin and bushing with lubricating oil, install the pin and fix it at the previously saved installation position to connect the air pipe, water pipe and power cord. 2. Measure the position and extension length of the spindle when changing tools. This is related to the thickness of the gasket on the spindle. Generally, the pin extension length is 0.5mm, with a maximum of 0.8mm. Then use a dial indicator to measure the front runout and rear end of the spindle, the main busbar of the spindle and the side busbar to complete the accuracy measurement of the spindle. 3. Write the positioning program for thespindle in MDI mode, press the “Run” key to execute, repeat the above steps to adjust the electric spindle to the horizontal tool change position, measure the accuracy of the electric spindle when released and cancel . the MDI state. 4. Return to the origin and manually change the tool for confirmation
It is necessary to add pads when rotating the turbogenerator to protect the machine and bearings. The specific operation steps are as follows:< /strong>
1. Stop the operation of the turbogenerator and park the machine in a safe place.
2. Open the machine cover, remove the original gasket and clean it for reuse.
3. Select new joints of appropriate thickness based on the number of joints required during turning.
4. Place the new seal on the bearing according to the position of the original seal, ensuring thatue the position of the joint is correct to avoid any deviation.
5. Reinstall the machine cover and make sure it is tight to avoid loosening.
6. Start the turning operation and observe the operation of the turbogenerator to ensure that the machine can operate normally.
