Common failures and solutions in the use of ultra-clean work stations

Ultra-clean work table in the use of common faults and solutions ultra-clean workstation is a general-purpose local purification equipment, it can create local high-clean air environment of the special equipment, ultra-clean workstation is in a specific space, clean air (infiltration air) in accordance with the set direction of flow and formation.
the air flow direction, the existing ultra-net work table can be divided into vertical, from the inside out and side-by-side.
from the operation quality and environmental impact to consider the vertical better.
The clean air provided by the air supply filter is lowered through the operating area at a specific speed, separated in the middle of the approximate operating area, sucked away by the front air suction hole and the rear suction window, mixed together by the air drawn in the lower front and rear of the operating area, and pumped into the rear positive pressure zone by the blower, where 30% of the gas is discharged from the top through the exhaust plate and re-entered through the oxygen filter.
the air emitted by the exhaust port, the same volume of air is replenished from the room air through the operating port.
air does not enter the operating area, but merely forms an air barrier.
common faults in the use of ultra-clean workbench: First, the total power switch can not close, automatic tripping.
cause of the accident: the fan stuck caused the motor to block, or the line has a short circuit.
solution: adjust the position of the fan shaft, or replace the imperms and bearings to check that the wiring is in good health.
, the wind speed is low.
cause of the accident: 1. The initial effect filter accumulates too much dust.
2. Efficient filter failure.
solution: 1. Clean the primary filter.
2. Replace the efficient filter.
, the wind speed is low.
cause of the accident: 1. Contactors do not work.
2. The fan power core has been fused.
: 1. Check that the contact line is ok.
2. Replace the melting core.
, fluorescent light is not on.
cause of the accident: 1. Damage to lamps or relays.
2. The lamp power fuse has been fused.
solution: Replace the lamp or relay.
