How to complete the maintenance work of industrial steam turbine during operation?

In addition to regular inspection and maintenance of industrial steam turbines, the steam turbine must also be well maintained during operation. What aspects need to be paid attention to during operation? Specific work content includes the following aspects.
When the industrial steam turbine is running, keep the equipment clean and pay attention to protecting the insulation layer.
During operation, the operator should record every minute. If the instrument reading is found to be different from the normal value, the reason should be identified.
Regularly inspect and calibrate various instruments on industrial steam turbines.
Regularly inspect the oil system to keep the pipelines clean and smooth, and there should be no oil leakage. The oil cooler should be flushed regularly, and the accumulated water and grease at the bottom of the oil tank should be drained out on time, and new oil should be added to keep the oil level normal. The oil filter should not be clogged. When the pressure difference between the front and rear of the oil filter exceeds, it should be switched to check the turbine oil regularly. quality.
Lubricating grease should be added regularly to each bearing lever joint and the sliding surface of the front bearing and seat frame. High-temperature resistant grease should be used on the spherical head pull rod on the adjusting steam valve lever and the bracket rotating shaft. Disulfide should be used on the fork joint. Molybdenum oil.
The water filter screen should be flushed regularly.
The electrical load is not allowed to exceed the maximum power of the industrial steam turbine.
The cycle change during industrial steam turbine operation should not exceed 1.
Move the valve stems of important valves such as the main steam valve and electric isolation door up and down once or twice every day to avoid valve stem sticking or seizure. This operation should be performed under low load.
If the steam turbine often carries a fixed load, the steam valve switch should be checked and adjusted regularly by changing the load in a short period of time to prevent the valve stem from getting stuck.
The inlet oil temperature of each bearing should be kept within the range of ℃, the temperature rise generally does not exceed ℃, and the lubricating oil pressure should be maintained at .
Conduct regular security system tests and automatic operation tests of electric oil pumps.
When industrial steam turbines are in operation, there are usually on-site staff, and the duty system must be arranged. When using it, it cannot be left alone. It is necessary to record regularly and pay attention to the values and operating status of each instrument for later use. Consultation during maintenance of industrial steam turbines.
