What are the guidelines for the use of decanter centrifuges?


The first thing to pay attention to use the decanter centrifuge is safety, the uncontrolled centrifugal force may cause great damage. Therefore, pay attention to whether the centrifuge tube is balanced, whether the speed exceeds the setting, whether the rotor is corroded, etc. Decanter centrifuges seem simple to use and have no technical content, but correct use and protection are still necessary. Once a failure occurs, it will delay the test, which is not worth the gain.

        1. When the centrifuge is in the pre-cooling condition, the centrifuge cover must be closed. After the centrifugation, the rotor should be placed upside down on the test bench, and the remaining water in the cavity should be wiped off. At this moment, the decanter centrifuge cover is in the open condition.

        2. When the rotor is pre-cooled, the rotor cover can be placed on the platform of the centrifuge or placed on the test bench. Never tighten the rotor and float on the rotor. Once it is started by mistake, the rotor cover will fly. Out and cause an accident!

  3. After the rotor cover is tightened, there must be no gap between the rotor and the rotor cover with your fingers. If there is a gap, unscrew and re-tighten the centrifuge until it is confirmed that there is no gap.

  4. During the centrifugation process, the operator must not leave the centrifuge room. Once an abnormal situation occurs, the operator cannot turn off the power (POWER) and press STOP. Fill in the decanter centrifuge usage record before pre-cooling.

   5. Do not use fake or inferior centrifuge tubes, and do not use aged, deformed or cracked centrifuge tubes.

   6. During holidays and evenings, the decanter centrifuge must undergo routine safety inspections before leaving.

  7. If there is a machine failure during the use of the instrument, and the parts are damaged, please contact the manufacturer in time.


Problems to be paid attention to when using decanter centrifuge

Problems to be paid attention to when using decanter centrifuge


Decanter centrifuge has good separation and washing effect under the action of centrifugal force, strong adaptability to materials, suitable for separating solid-phase particles ≧0.01mm suspension. Decanter centrifuges are widely used in biochemistry, fine chemicals, pharmaceuticals and other fields. It is a filter centrifuge with automatic scraper discharge and intermittent operation.

  1. Precautions for the use of decanter centrifuge

    (1) Fabrics with different water absorption strengths should be dehydrated separately.

    (2) The newly installed dehydrator or the newly connected wire must ensure that the motor rotates in the correct direction.

    (3) When the fabric is placed severely unevenly and causes intense vibration, the power switch should be turned off immediately, and the fabric should be placed evenly from the beginning before dehydration.

    (4) Do not overload the amount of fabric placed. Especially pay attention when taking off other items other than clothing.

    (5) When the machine is working, do not reach into the inner cage area of ​​the dehydrator

2. How to use the decanter centrifuge?

    (1) Before use, first check whether the mechanical parts are in good condition.

    (2) Place the level meter washing evenly in the inner rotating cage.

    (3) Start the electric motor to gradually accelerate the speed of the inner cage. According to the type of fabric, it can be dried in 5-10 minutes.

    (4) Press the "Stop" button to power off the motor. After the dehydrator has been naturally decelerated for a period of time, manipulate the brake lever to perform intermittent braking operations to complete the stop of the inner cage.

    (5) After the machine stops, the fabric can be taken out.

How to operate the decanter centrifuge correctly 


Decanter centrifuges are used more and more frequently in the production field. Of course, as staff, we must be proficient in relevant operating skills. Only in this way can we use them reasonably and make them in ideal working conditions. So for the decanter centrifuge equipment, what is the correct operation method in detail? Next, let's take a look at the detailed content.

   Obviously, if the correct operation method is used, it can not only ensure the normal progress of our work, but also effectively extend the service life of the decanter centrifuge, and also effectively reduce the failure rate of the equipment. So, how do you do it after all? First of all, we must ensure that the equipment is placed on a flat surface and fixed.

   After confirming that there is no abnormal problem, connect the appropriate power supply voltage to the equipment, and install it back as required, and then place the material in the decanter centrifuge cavity. After that, close the door of the equipment, and set the temperature, speed, time and rotation speed according to the actual situation. Then open the equipment and enter the state of normal production. In this process, you should pay attention to the operation status of the decanter centrifuge, and deal with it in time if any problems are found.

   When the separation work is completed, we should shut down the equipment, and only after the decanter centrifuge is completely stopped, can we open the door and take out the separated material. After that, use a clean cloth to scrub the inside of the equipment and back, and keep it clean. After that, the temperature of the internal cavity of the device is consistent with the room temperature, and then the door is closed.

The correct use method of decanter centrifuge is as above. As long as we use the equipment according to the correct use method, and conduct inspection and maintenance at regular intervals, then the service life of the equipment can be extended. I hope this article can help you understand the decanter centrifuge equipment more comprehensively.

        1. Strong craftsmanship. Because the control system selected by the equipment is very good, it can actively adjust at any time according to the material condition during operation, and the treatment effect has been achieved.

     2. Low noise. In the structural design, a double-layer and sound-insulating layer design was specially selected. Therefore, during operation, the announced noise is very small, and the impact on the environment of the work site is also small.

      3 Higher degree of automation. During the operation of the decanter centrifuge, whether it is feeding, separating or unloading, each link is continuously and actively carried out under high-speed operation, so the it is very convenient and simple to operate.

      4, The processing capacity of this equipment is very large. Because of the structural improvements, it can handle more materials together.

        5, The decanter centrifuge will not have too much impact on the working environment on site. Because the equipment is carried out under completely enclosed conditions during the entire operation process, there is no need to worry about pollution at the operation site and clean production is completed.

    6. The working function of this equipment is very stable, so it can maintain high working efficiency with stable performance during operation.

   7, The decanter centrifuge is very safe and very reliable. Because the equipment is specially equipped with multiple protection devices, the decanter centrifuge has high safety features, and the users can use it with enough confidence.
