Cement negative pressure screen analyzer operating procedure
Cement negative pressure screen analyzer operating procedures:
1. Before the screening test, the negative pressure screen should be placed on the sieve seat, the screen cover should be covered, the power supply should be turned on, the control system should be checked, and the negative pressure should be adjusted to the range of 4000~000Pa to check whether the instrument is working normally.
2. Weigh 25g of cement sample, place it on a clean negative pressure screen, cover it with a sieve cover, place it on the sieve seat, and start the sieve for two minutes. During this time, if cement adheres to the screen cover, the sample can be gently tapped to drop.
3. After the negative pressure sieve analyzer stops working, the balance on the sieve is weighed with a balance.
4. When the working negative pressure is less than 4000Pa, clean the cement in the vacuum cleaner during emergency to restore the negative pressure to normal.
5, the test sieve must be kept clean, the screen hole is smooth, so every time after the completion of the test, the cement on the sieve must be gently brushed off with a brush.
6. The negative pressure screen analyzer should maintain its horizontal position during operation to avoid external vibration and impact.
7. If the rubber sealing ring is aging or damaged after using the instrument for a period of time, it should be replaced in time to ensure an effective sealing state.
Precautions for cement negative pressure screen analyzer:
1. It is forbidden to use the equipment and equipment for the test staff or professional maintenance personnel of this project.
2. It is forbidden to start the equipment when the voltage is unstable.
3. If there is any malfunction of the electrical equipment during the use of the machine, the power should be cut off in time and reported to the maintenance personnel for inspection and maintenance.
Maintenance of cement negative pressure screen analyzer: The testing machine should be kept clean; always check whether the contact parts of the power supply and the sensor are loose or burnt, if it should be replaced in time to prevent accidents; the cement in the glass bottle on the side of the instrument should be Clean up often.
