when A vacuum pump to run for A period of time ( Such as 10 s) Online, the system has not reached negative pressure set value, B pump, A pump and B pump running at the same time, system to online negative pressure value, the A and B pump stop, equipment normal use; When the system reaches the negative pressure logoff, B pump starts to run, run for a period of time ( Such as 10 s) Set of online value, B and C pump running, online system to negative pressure value, B and C pump stop, equipment normal use; When the system is offline again negative pressure value, C pump starts to run, run for a period of time ( Such as 10 s) Set of online value, C pump and A pump running, online system to negative pressure value, the C pump and A pump stop, equipment normal use of A water pump, B, C pump according to the order of AB BC CA starting alternating operation automatically.

4, each vacuum pump is equipped with independent control switch, at the time of any water pump failure, do not affect the other two pump use.
