Embodiment
Below in conjunction with drawings and Examples, the utility model is specifically described.
It is major loop schematic diagram of the present utility model described in Fig. 1.
It is control loop schematic diagram of the present utility model described in Fig. 2.
The utility model comprises a low pressure fuel pump and No. two low pressure fuel pumps, and a described low pressure fuel pump and No. two low pressure fuel pumps are controlled by control loop.
Described COMM communication comprises a main pump selector switch SA1 and two time relay KT1 and KT2, two pairs of contacts of described main pump selector switch SA1 control two time relay KT1 and KT2 respectively, and the normally opened contact of the power cut off delay of described time relay KT1 and time relay KT2 is connected respectively in the control loop of a low pressure fuel pump and No. two low pressure fuel pumps.
When time relay coil obtains electric, the normally opened contact of power cut off delay closes immediately; When time relay coil power-off, closed power cut off delay normally opened contact just can disconnect to rear at the delay time of setting.Utilize the feature of time relay power cut off delay, when stirring main pump selector switch SA1, when a low pressure fuel pump or No. two low pressure fuel pumps run, first start No. two low pressure fuel pumps or a low pressure fuel pump, the power cut off delay time stops automatically to a low pressure fuel pump of rear operation or No. two low pressure fuel pumps, therefore, during maintenance main pump, do not need to stop grinding machine, ensure that normal production.
The control loop of a described low pressure fuel pump comprise connect successively time relay KT1, stop button SB1, start button SB2, motor breaking device QF2 and motor AC contactor KM1, time relay KT1 connects main pump selector switch SA1 by L01 line, and motor AC contactor KM1 is connected with a low pressure fuel pump motor M 1.
The control loop of described No. two low pressure fuel pumps comprise connect successively time relay KT2, stop button SB3, start button SB4, motor breaking device QF3 and motor AC contactor KM2, time relay KT2 connects main pump selector switch SA1 by L01 line, and motor AC contactor KM2 is connected with No. two low pressure fuel pump motor M 2.
