Installation, use and maintenance of ultra-clean workbench

Install and use

The working place of this workbench should be in a clean working room (preferably placed in the primary purification room of 100,000 or 300,000 class), plug in the power supply, and turn it on according to the function shown on the control panel. Before starting the machine, the work surface and the casing of the purification station should be carefully cleaned to remove surface area dust. Normal operation can be carried out ten minutes after the machine is turned on.

maintain

1. According to the actual use situation, the primary effect filter is removed and cleaned regularly, and the cleaning cycle is generally 3-6 months. (If it is not cleaned for a long time, dust accumulation will affect the insufficient air intake and reduce the cleaning effect.)

2. When the air filter of the primary effect filter is normally replaced or cleaned, and the ideal cross-sectional wind speed cannot be achieved, the working voltage of the fan should be adjusted to achieve the ideal uniform wind speed.

3. Generally, when the working voltage of the fan is adjusted to the highest point after the use of 18, and the ideal wind speed is still not reached, it means that the high-efficiency filter has too much dust (the filter hole on the filter material has been basically blocked, and it must be updated in time) In general, the service life of high-efficiency air filters is 18 months.

4. When replacing the high-efficiency air filter, pay attention to the correctness of the model specifications (original manufacturer configuration), according to the arrow wind direction device, and pay attention to the seal around the filter, absolutely no leakage occurs.

General failures, causes, and troubleshooting

Fault phenomenon

the reason

Discharge method

The main power switch fails to close and automatically trips

1. The fan is stuck causing the motor to stall or the circuit is short-circuited

1. Adjust the position of the fan shaft, or replace the impeller and bearing, and check whether the circuit is intact.

2. According to the circuit diagram, check the insulation resistance of the circuit and components to the housing point by point to repair the insulation failure.

Low wind speed

1. Excessive dust accumulation in the primary filter.

2. The high efficiency filter is invalid.

1. Clean the initial effect filter.

2. Replace the high-efficiency filter.

The fan does not rotate

1. The contactor does not work.

2. The fan power fuse has blown.

1. Check whether the contactor circuit is normal.

2. Replace the core.

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 lamp or relay.

2. Replace the core.
