Gasification workshop: the king of Huainan

Coal mill pressure rod up and down movement, because of wear plate pressing frame side wear, a pull rod and a joint bearing is not concentric joint bearing rod is easy to be pulled out above cause. Through their own observation groping improvement measures have been taken: 1, timely adjustment of the wear plate gap repair grinding coal machine, ensure the concentricity of the pull rod and bearing; 2, outer ring of the joint bearing is welded on the pressing plate. After running the test, the effect is obvious, bearing no pulled out, greatly prolonging the operation cycle of the coal mill.

Urea workshop: Liu Pingyang

The three phase of urea 1# reflux pump often leak repair, although for many times, still can not solve, finally can only change into the packing seal into the standby pump, suggestions or to use sealing machine workshop, workshop agreed to let the repair. The pump head open, after observation and analysis, found that sleeve friction traces is very serious, is the main pump sleeve and a static ring seat caused by friction with the car off the lathe axis, 1 mm, installed after the test found, seal cooling water is not smooth, found no problems removed, after careful observation, that should be the middle gasket the machine seal housing two gland, the gasket car off a ring, after testing the waters of normal equipment, the whole assembly, the pump in normal operation, eliminates leakage.

Purification workshop: Chen Xiaojun

Recent methanol washing section regeneration system condition regeneration effect is not ideal, through their own observation, not because of a small amount of steam is the main reason, the fundamental reason is: 1, FV49 and C2205 exceed the standard small open through lead tower overload. 2, C2204 tower bottom temperature is low is another cause of (lead exceed the standard C2205 overload). 3, the operating personnel in order to reduce the consumption without reducing the C2205 bottom steam supply amount. Operation control method: 1 control the opening degree of FV49 is about 20%; 2, to keep the temperature at T225 - 45, not easy to be too low, the C2205 tower steam addition amount is strictly prohibited without cause reduced; 3, regular plus do lean degree analysis, ensure the absorption of poor degree. Through the above method, can prove that the control system and the poor degree in technology target.

Boiler shop: Chen Qinghai

By the coal particle wear serious pipe coal boiler, often leaking coal ash leakage, not only result in waste, but also environmental pollution, often caused by welding and increased labor costs. After the test, in the lower coal tube leak a castable join welding plates, in the sealing welding solid. After the operation greatly extend the using time of the coal pipe, the effect is remarkable.

Workshop: Chen Zhidong

Some time ago, ice machine oil pump shaft oil leakage, repair a few times still can not solve the. It passed the observation of thinking, determine the front lid has a problem. The gap between the static ring and moving ring is 2 - 3 mm, 1 mm with asbestos mat, dynamic, static ring gap between 2-4 mm, but the elastic force of the spring ring is not enough, resulting in dynamic, static ring sealing effect is not good, after the opening, easy to leak, the front end on the 1 mm asbestos pad into the rubber ring seal, so the end cover sealing, and solves the problem of oil leakage of sealing machine, the effect is very good.

Electrical instrument workshop: Wang Liang

In October 20th the day shift, the discovery of 5# main transformer on load regulating switch mechanical linkage action automatically adjust the voltage regulating switch is abnormal in the inspection, timely stop 5# the main load voltage control power supply. Because is higher than the rated voltage will cause harm to the equipment and protection, and inform the workshop for treatment, avoid the equipment and the protection of an unnecessary damage.

Gasification workshop: Zhang standard

Recommendations in the workshop supercharger pressure test question, and was adopted, workshop, better completed the supercharger pressure test.

1, put pressure rise speed, guarantee the smooth unit speed.

2, pressure lifting, close the valve as far as possible to accept the end of air defense anti valve, ensure the normal intake. 3, boost, try to open the import.

4, in the process of pressure test, collect the vent should be open reflux valve, ensure the flow back to a certain.

5, should pay attention to points of each vibration change and the unit anti endpoint pressure process.
