The compressor is directly coupled to the drive unit and the unit is mounted on a floor with a lubrication system, control system and various auxiliary devices. The lubricating oil is sucked out from the oil storage tank located in the bottom plate and flows through the oil pump, the shell-and-tube oil cooler, the thermostatic control valve, and then flows through the oil filter to the compressor gear, pinion, motor bearing and expander bearing. Finally, the lubrication points are returned to the fuel tank. In order to maintain the oil temperature of the compressor bearings at a normal operating temperature of 40 to 46 e, sufficient water must flow through the oil cooler. In the second half of 2000, when the shaft vibration increased, it was found that the temperature change of the lubricating oil was also larger than usual. Due to the normal fluctuation of the circulating water temperature, we suspect that there is an abnormality in the thermostatic control valve.
The valve is an oil temperature self-inductance regulating valve, and the inside is a temperature sensing bag with a metal piece. If the oil temperature rises, the metal piece expands after being heated, the V-shaped spool moves, and the oil volume of the oil cooler increases. The oil temperature drops. During the overhaul in April 2001, the instrument personnel checked and confirmed that the temperature sensor had failed. After replacing the temperature sensor package with spare parts, the oil temperature has been stable for nearly one year.
The wiring of the instrument is easy to loose, the compressor frequently jumps due to the vibration of the shaft, the process and instrument personnel repeatedly check and verify on the spot, and find that the joint is loose, tightening, delaying and reducing the number of stops, but sometimes the fastening will cause the jump. . The reason is probably because the control cabinet is too close to the unit, the joint is vibrated and loose for a long time, causing poor contact, and the transmission signal is unstable and distorted, resulting in an interlocking action. During the overhaul in April 2001, the shaft vibration and shaft displacement monitoring cabinets were moved from the compressor room to a room 15m away. In the 11 months after the overhaul, the phenomenon that the shaft vibration was too high due to loose joints did not occur again.
Wheel mill is used to stir coal powder, charcoal powder, slime, middlings, coking coal, coke breeze, dusting ash, pond slob, fire coat, steel slag, iron fine power, aluminum ash powder,etc. Usually, we mix some binders to stir charcoal powder and make powders easy to shape.
The binder mixer machine is a special mixing equipment for the briquette production line to process binding agents in the chemical area. It will mix the binder successional so as to achieve the expected results.
