structure characteristics
The biosafety cabinet consists of several major components such as the box body, fan, high-efficiency filter, and operation switch. The box is made of materials, with a surface treated with spray coating, and the workbench is made of stainless steel. The purification unit adopts a fan system with adjustable air volume. By adjusting the operating conditions of the fan, the average wind speed in the clean working area can be maintained within the rated range, and the service life of the high-efficiency filter can be effectively extended.
working principle
Inhale air from the top of the box, and under the drive of the supply fan, send the air into the static pressure box, filter it through a high-efficiency filter, and then send it to the safety cabinet operation area. After mixing the descending airflow with the air sucked in from the opening of the safety cabinet operation area, it is discharged outdoors through the external exhaust duct driven by the central exhaust system or external exhaust fan, filtered by the exhaust filter.
Installation and use
The location of this biological clean safety cabinet should be in a relatively clean working room (located in a primary purification room of 100000 or 300000 levels), plugged in the power, and turned on according to the functions shown on the control panel. Before turning on, the working area and shell of the biological clean safety cabinet should be carefully cleaned to remove surface dust. Normal operation and use can be carried out ten minutes after turning on.
maintain
1. Generally, when the working voltage of the fan is adjusted to the desired level after 18 days of use, and the ideal wind speed cannot be achieved, it indicates that the high-efficiency filter has accumulated too much dust (the filter holes on the filter material are basically blocked and need to be updated in a timely manner). The service life of a high-efficiency air filter is generally 18 months.
2. When replacing the high-efficiency air filter, attention should be paid to the correctness of the model, specifications, and dimensions (original configuration), install the device according to the direction of the arrow, and pay attention to the sealing around the filter to ensure no leakage occurs.
General faultsReasons and elimination methods
Fault phenomenon |
reason |
Discharge method |
The main power switch cannot be closed and automatically trips |
1. Fan jamming causes motor stalling or short circuit in the circuit |
1. Adjust the position of the fan shaft, or replace the impeller and bearings, and check if the circuit is intact. 2. Check the insulation resistance of the circuit and components to the casing point by point according to the circuit diagram, and repair the insulation fault. |
Low wind speed |
1. The high-efficiency filter has failed. |
1. Replace the high-efficiency filter. |
The fan is not turning |
1. The contactor is not working. 2. The fuse of the fan power supply has blown. |
1. Check if the contactor circuit is normal. 2. Replace the melt core. |
The fluorescent light is not on |
1. The lamp or relay is damaged. 2. The fuse of the lamp power supply has blown. |
1. Replace the light tube or relay. 2. Replace the melt core. |
