Debugging of manual scraper centrifugeThe work can generally be divided into 6 steps, and the centrifuge can be safely debugged according to each step.
*The main inspection steps are to see if the scraper is in the reset state; Reliable braking device; The controller switch must be in the closed position; The speed control knob is in the "O" speed position; The foot bolts must be tightened tightly; External equipment and devices connected to the machine must be installed reliably; After single machine and linkage testing, the technical condition is good, and the lubrication parts are well lubricated. Only when these items meet the requirements can we proceed to the next part
Secondly, connect the power supply and rotate the motor in the direction indicated on the nameplate. Do not reverse, and proceed to the next step in sequence.
Thirdly, turn on the controller switch, the indicator light will turn on, slowly rotate the speed control knob, the speed control motor will start, and the drum will gradually accelerate until the loading speed is reached. When the drum is running, the material is fed through the feeding tube to the feeding tray. The feeding tray rotates at the same speed as the drum, and the material obtains centrifugal force from the feeding tray and is thrown onto the drum wall. If the speed is still low, the material cannot obtain sufficient centrifugal force and falls directly from the discharge hopper. If the speed is too high, for some materials (media), the material will be filtered out of the liquid in a very short time in the drum, causing poor flowability of the material in the drum and affecting the balance of the feeding, thereby causing machine vibration. Therefore, the loading speed refers to the speed at which the material (a certain type of material) can obtain sufficient centrifugal force on the fabric tray without falling directly from the discharge hopper, and can have good flowability in the drum to balance the loading on its own. The loading speed of various media is not the same, and it needs to be determined based on the specific gravity and physicochemical properties of different materials during actual operation.
The fourth step is to start feeding: open the feeding valve and start feeding until the rated loading capacity or loading capacity is reached.
Fifth, turn the speed control knob to the rated speed to further separate the materials. If the filter cake needs to be washed, open the washing valve to wash the filter cake and filter out the washing solution. After washing is complete, close the washing valve. Depending on the separation of materials or the requirements for the filter cake, a further period of high-speed operation can be continued to filter out as much liquid as possible from the filter cake.
Sixth, turn off the controller switch, place the speed control knob in the "0" position, tighten the brake handle to slow down the drum until it stops rotating, and then release the brake handle.
The above 6 types of centrifuges can run well and smoothly, indicating that the centrifuge meets the standards, and the debugging work of the scraper centrifuge is basically completed.
