Maintenance of centrifugal deaerators

Centrifugal deaerator maintenance is a daily work
that operators must carry out in order to maintain the normal operating condition of the machinery and extend the service life.
Neatness: tools, workpieces, accessories are placed neatly, safety protection devices are complete, and lines and pipelines are complete; Cleaning: clean inside and outside the equipment, no oil pollution and no bumps on each sliding surface and lead screw, gear, rack, etc.
, no oil leakage, no water leakage, no air leakage, no electricity leakage in all parts; Cleaning of the swarf garbage; Safety: implement the system of fixing personnel and machine and handing over shifts, be familiar with the equipment structure and abide by the operating procedures, use the equipment reasonably, carefully maintain the equipment, and prevent accidents
.
The content of on-site equipment maintenance management equipment maintenance work can be divided into daily maintenance and regular maintenance according to time; According to the maintenance method, it can be divided into general maintenance, regional maintenance and key equipment maintenance
.
Maintenance work generally includes; View, inspect, adjust, lubricate, disassemble and repair on-site management and maintenance work
.
The regional maintenance equipment of centrifugal deaerator is divided into several areas according to the amount of equipment or equipment type in the production area, and the maintenance workers have a clear division of labor and cooperate closely with the operators, responsible for supervising and guiding the equipment operators in the area under their jurisdiction to operate correctly, use reasonably, and carefully maintain the equipment; Carry out roving inspection, master the operation of equipment, and undertake certain equipment maintenance work; The deaerator should be cleaned and inspected after daily operation; That is, the so-called technical maintenance should be completed on time and in accordance with the items; This is a type of seasonal maintenance that will be carried out temporarily before the arrival of winter or in summer; Its purpose is to adapt the work of the deaerator to solve the changing requirements
.
Centrifugal deaeration machine maintenance knowledge: before starting, check whether each switch, knob and are placed in the stop or required position; Spindle asbestos packing should pay attention to pressing, if it fails, immediately replace the asbestos rope coated with grease, adjust the gland, and ensure that the spindle is in a good sealing state; There should be enough lubricating oil in the worm gear reducer, no oil leakage in each rotating part, and the bearing retaining ring needs to be refueled 2-3 times a day; For a long period of use or shutdown, it should be run for 3-5 minutes without load first, and confirm that the lubrication, sealing, electrical control, grouting system and pressure grouting are normal before work; Check the connection and sealing of the vacuum degassing and pressure grouting system pipes connected to this machine, which must be correct and intact; After 24 hours of continuous operation, the temperature rise of each rotating part shall not be higher than 60 °C; The container seal must be reliable, the vacuum degree shall not be lower than -0.
07Mpa; after stopping the vacuum, close all vacuum pipeline valves, open the compressed air valve, enter the compressed air, and the compressed air pressure will gradually increase in the range of 0.
15-0.
08Mpa (selected according to the process requirements); At this time, the valve of the pressure grouting system can be opened for grouting molding; The mud progress must be checked from the observation hole after stopping, and the pressure in the tank should be within the range of 0.
20Mpa; after the end of each day, the residual slurry should be drained, and the slurry barrel and the inlet and outlet pipeline
should be cleaned 。 Be sure to unplug the power plug before cleaning the centrifugal deaerator; Please wipe the shell with a towel dipped in a soft detergent (such as hand sanitizer), and do not let water fall into the machine; In order to avoid rust affecting the use; Do not use hard objects such as wire brushes to wipe the equipment; It is not allowed to use bad cleaning agents and corrosive and volatile chemical solvents to wipe the fuselage to avoid damage to the fuselage; Do not plug in during maintenance; Avoid unnecessary accidents caused by leakage; Do not share a socket with other electrical appliances with large power consumption, so as not to overload the circuit and cause a fire; Clean the cup holder
.
Clean the surroundings and don't have other debris next to you
