Drilling hot water pump station automatic control device mainly solves the existing hot water pumping station without temperature automatic control device. Characterized in that terminals 1, 2 and 3 for inputting temperature detection signals on the thermostat (WK) are electrically connected to the temperature probes via flexible wires and are used for outputting 6, Terminal 7 is electrically connected to the terminals 1 and 2 for inputting the control signal via a flexible wire and to the central controller (ZK); the relay KA3 is connected between the two-phase power supplies via a KK handle, Normally open contact is connected between the power supply and the power input of the thermostat (WK); the normally open contact of the central controller (ZK) is connected in parallel with the energized control part of the AC contactor coil, The contacts are in series with the loss-of-control section of the AC contactor coil. The utility model ensures that the hot water pumped out from the hot water pumping station can meet the requirement of the drilling mud for injecting water temperature in real time and ensure the safety of the drilling construction.
