Row.
Since water supply tank does not have water level automatic monitoring controller, operator can not timely and effectively observe water
Case cooling water water level conditions.It is possible that water supply tank fans the air, small pump air inlet leads to low temperature central air-conditioner cooling water amount not
Foot, water switch the failures hairs such as stoppage protection, pump mechanical seal water damage.Or there is personnel's operation error, water supply tank water inlet hand-operated valve
It is not turned off, water supply tank is caused to overflow water, the situations such as waste and equipment fault is caused to occur.In order to guarantee cooling water water as far as possible only
It is more or very few, operations staff must 2 ~ 3h make an inspection tour primary, and moisturizing is carried out to water supply tank.
Summary of the invention
The phenomenon that avoid the occurrence of moisturizing not in time, occurs and reduces personnel labor intensity, and the utility model provides a kind ofly
