DOWNLOAD MANUAL INSTRUCTION

The CF30 series centrifuge is top discharging, hermetic closure type equipment. The material is fed into the drum through the feeding pipe on the hermetic closure casing; under the action of the centrifuge force field, the liquid-phase passes through the filter medium and the discharged out of the machine, while the solid-phase material is retained inside the drum and, after the machine is stopped, the material is discharged from the top. The centrifuge has features such as smooth running, easy & convenient operation as well as conducting feeding, washing and dehydrating under the state of hermetic closure, etc.

Machine operation and maintenance

1. Empty load operation
After the centrifuge is checked before starting the work, start the motor to check whether the direction of rotation of the drum is the same as the direction of the arrow on the fuselage. Start the motor. After the machine reaches the rated speed, check for abnormal noise. No special situation, no operation. After 3 hours, stop the machine and check if the spindle nut and other fasteners are loose. The temperature rise is normal at 55℃ outside the ambient temperature.

2. At work
Before working, turn on the air seal of the shaft seat and pass 100~200 mbar of nitrogen gas. Fill the cover with nitrogen gas to not exceed 50 mbar. Put the material to be separated into the special filter bag and put it into the drum (note the loading amount).
Do not exceed the weight of the nameplate calibration, add appropriate amount of solvent, rotate at a low speed of 3HZ~5HZ, and after a certain time, rotate at the rated speed and completely dehydrate.

3. Unloading
The discharge of the centrifuge should be carried out after the separation is completed or the washing separation is completed. After the machine has completely stopped rotating, open the upper cover and all the locking devices to discharge.

4.Abnormal situation processing
When the machine has abnormal noise or severe vibration, stop immediately, find and try to solve the problem for the following reasons, otherwise it will reduce the life of the machine and even cause an accident.
(1)Uneven material in the drum causes abnormal vibration, and the vibration can be eliminated by evenly placing it again.
(2)Is the water outlet blocked by the crystal of the filtrate? If it is blocked, the fuselage will be filled with filtrate, and the basket will rotate in the water. The resistance will increase and vibration will occur. If this happens, the water outlet should be used. Crystallization is removed.
(3)The filter bag should be cleaned in time. The filter bag separates the fine particles for a long time, which will block the filter hole of the filter bag, so that the filtration performance is reduced, and the material flows in the basket, causing vibration.
(4)The filter bag is damaged, and the liquid passes through the damage, causing filtering vibration. Therefore, it is necessary to check frequently and replace the filter bag in time.
(5)In addition to the above reasons, the bearing housing and the chassis fastening screws are loose, and machine vibration is also generated. The deformation of the drum during use will also create imbalance. If it is not checked and eliminated, the spindle and other parts will be easily broken, resulting in an accident. After long-term use of the drum, the basket wall will be corroded and the strength will be reduced. , pay attention to check.

5.Periodic inspection
When the machine is used to separate corrosive materials, the user should formulate a regular replacement system according to the corrosion degree of the materials. Generally, the centrifuge is inspected once a month, and the drum is inspected once per shift. If drum or drum welding is found. When the seam corrosion is serious, the drum should be replaced immediately to avoid the drum explosion accident!

6. Maintenance
(1) Maintenance of bearings
Lubrication of the bearing can be carried out without disassembling the machine. There is an oil filling pipe on the bearing seat of the machine. The main bearing is injected with an appropriate amount of grease for 1000 hours. It is recommended to use low temperature butter grease for temperature -80 °C~ 200 ° C.
(2) Disassembly of the basket
Remove the bolts on the shaft end of the spindle, loosen the basket with 2 bolts, screw the two eye bolts into the process screw holes on the bottom of the basket, and thread the wire into the ring (the wire rope must ensure that the drum is balanced) Tilt) and lift the drum.
(3) Bearing replacement
After the basket is disassembled, remove the centrifuge belt, loosen and unload the bolts of the bearing housing, screw into the screw holes on the spindle with the self-made special lifting ring, and lift the spindle and the spindle seat out of the machine with the sling. Well, remove the pulley fixing device, unload the spindle pulley with the belt tweezers, remove the lower cover of the shaft seat, remove the round nut of the lower bearing, loosen the bolt of the gland on the shaft seat, and gently shake the end of the spindle with a hammer. Until the main shaft is separated from the bearing housing, the main shaft is lifted from the upper part of the shaft base, and then the tool is used to remove the lower bearing from the inner space of the shaft seat. Remove the circlip on the lower part of the upper bearing and loosen the upper bearing to remove it in the direction of the small end of the shaft.
