Slurry pump control device and control method thereof

Abstract

The invention relates to a slurry pump control device and a control method thereof. The device comprises a programmable controller, an operation panel, an engine sensor and transducers. The operation panel is connected with the programmable controller, the programmable controller is connected with a slurry pump, and the engine sensor is connected with the programmable controller through the transducers. The programmable controller receives instructions sent by the operation panel and then sends signals to the slurry pump to control separation and closing of a clutch of the slurry pump, starting and extinguishing of an engine of the slurry pump and the opening degree of a an accelerator. The engine sensor sends all parameter information of the engine to the programmable controller through the transducers. The programmable controller sends a specific instruction to the slurry pump when judging that the engine is in an abnormity, and the slurry pump executes the specific instruction, in other words, the engine of the slurry pump is emergently stopped. By means of the technical scheme, compared with the prior art, automation work of the slurry pump is achieved, a clutch separation shaft sleeve is protected, and the purpose of saving energy is achieved; remote control and wireless remote control are achieved, manpower resources are saved, the working environment is improved, and the potential safety hazard brought by manual operation is eliminated.

Description

technical field [0001] The invention relates to the field of geological exploration equipment, in particular to a mud pump control device and a control method thereof. Background technique [0002] When the mud pump is used in conjunction with the trenchless drilling rig, it can transport the mud required for drilling for the drilling rig, but when the drilling rig replaces the drill pipe or suspends drilling for other reasons, it needs to stop delivering the mud. The existing method is to manually put the mud pump gearbox into neutral or manually disengage the mud pump clutch. Due to the inconvenient adjustment of the mud pump engine throttle, it is not reduced. The disadvantage is: due to the mud pump engine The throttle is not reduced, there will be a lot of unnecessary fuel consumption during the standby process, and the clutch release bushing is easily damaged when the clutch is engaged and disengaged under high-speed operation of the engine; in addition, the mud pump h...

Problems solved by technology

The existing method is to manually put the mud pump gearbox into neutral or manually disengage the mud pump clutch. The throttle of the mud pump engine has not been reduced due to the inconvenience of adjustment. The disadvantage is that: because the mud pump engine If the throttle is not reduced, there will be a lot of unnecessary fuel consumption during the standby process, and the clutch is easily damaged when the engine is running at high speed and the clutch is disconnected; in addition, the mud pump has noise and exhaust gas pollution, and requires special personnel Operation increases labor costs, reduces construction efficiency, seriously affects the health of operators, and brings hidden dangers to workers' personal safety.
