The control and execution terminal receives a control instruction of a system (the oil distribution box is provided with a PLC controller and communicates through a communication network-485, CAN and the like), and returns the effect of controlling and executing.

There are two modes of control of the split tank opening valve:

timing quantitative mode: the grease is supplied in a fixed amount for a predetermined period of time, for example, 24 hours for 1 day, 3 times per lubrication point, i.e., 8 hours/time, and 5mL per supply. The oil supply is performed with 8 points opened in sequence.

B full-time execution, i.e. intermittent continuous oil supply to individual points, for a specific point, the intermittent interval time may be set to 1 minute (the duration may vary completely from 1 minute to 24 hours, which is complementary to the above-mentioned pattern), i.e. 0.5mL oil supply at a time to a single lubrication point.

Each branched oil tank has 8 oil outlet points, and can execute B mode for the 1# oil outlet and execute A mode for the 2# -8# oil outlet.

The driving mechanism, the multi-shaft parallel straight tooth speed reducer and the belt stepping direct current motor structure realize multi-circle rotation, and the shaft is accurately positioned in the circumferential direction by the rotation of the motor without any other retarding mechanism.
