How does the twin-screw granulator prevent fire? Doing so will prolong its life!

by:TENGDA     2022-12-14
In fact, for the twin-screw granulator, daily fire prevention measures are also very important, because if it catches fire, it will be very dangerous to the machine and the operator. Its fire prevention measures can be carried out based on checking the operation, reasonable selection, maintaining a safe equipment location, maintaining normal operation, ventilation, and grounding. In the article, TENGDA Plastic Extruder Machine Manufacturers will give you a detailed introduction on the fire prevention measures of the twin-screw granulator and the method of prolonging its service life.

Fire prevention measures for twin-screw granulator:

1. Check the operation status

Always check the operation of the twin-screw granulator, check whether the joints are loose, whether there are electric sparks, whether the overload and short-circuit protection equipment of electrical and mechanical equipment is reliable, and whether the insulation of the equipment is up to standard.

2. Reasonable selection

Where there are flammable and explosive materials, when the equipment uses a twin-screw granulator, explosion-proof electrical appliances should be used, and the insulated wire must be sealed and laid in the steel pipe. The electrical equipment should be selected and equipped according to the level of explosion risk places.

3. Adhere to a safe equipment location

Adhering to the necessary safety distance is one of the important measures for fire prevention of the twin-screw granulator. In order to prevent fires caused by sparks and high-temperature risks of the twin-screw granulator, flammable and explosive materials should not be piled up around the twin-screw granulator that can cause sparks and high temperatures.

4. Adhere to normal operation

The sparks and risky high temperature that occur during the operation of the twin-screw granulator are important causes of fires in electrical machinery. In order to control excessive sparks and dangerous high temperature and ensure the normal operation of the twin-screw granulator, it should be operated, operated, maintained and maintained by trained and qualified personnel.

5. Ventilation

Twin-screw granulators operating in flammable and explosive places should have good ventilation to reduce the concentration of explosive mixtures. Its ventilation system should meet the relevant requirements.

6. Grounding

The grounding requirements in places with flammable and explosive risks are higher than those in general places. No matter its voltage is high or low, normal uncharged equipment should be firmly grounded according to relevant regulations.

Ways to prolong the service life of twin-screw granulator:

1. The basis of daily maintenance is to clean the machine and lubricate the moving parts of the granulator. For example, there will be iron filings or other impurities from gear grinding in the gearbox, check the wear of gears and bearings and make records. Clean the gears and replace the gearbox lubricating oil at the same time.

2. Experts from the parallel twin-screw granulator service provider said that after a period of use, it is necessary to conduct a comprehensive inspection of the granulator, check the tightness of all screws, and make records. Confine the loose threaded parts and check them in real time to prevent failures during operation.

3. Check and adjust the motor, control instrument, various pipelines and working parts of the twin-screw granulator. If the power is suddenly cut off during production, the main drive and heating stop, and when the power is restored, each section of the barrel must be reheated to the specified temperature and held for a period of time before the granulator can be started.

4. The inner wall of the cooling water pipe attached to the twin-screw granulator is prone to scaling and the exterior is prone to corrosion and rust. Careful inspection should be done during daily maintenance. Excessive scale will block the pipeline, and the cooling effect will not be achieved. Severe corrosion will cause water leakage. Measures for descaling and anti-corrosion cooling must be taken during daily maintenance.
