[0002] At present, the mining pneumatic diaphragm pump used in the coal industry is mainly used for underground drainage operations in mines. The compressed air circuit connected to it is in a normal state, and the switch of the equipment needs to be controlled manually. Diaphragm pumps are often left unattended, so that the equipment is still running in an anhydrous state, resulting in: on the one hand, the diaphragm of the diaphragm pump operates under no load, reducing the service life of the diaphragm and the whole machine; On the one hand, it causes unnecessary waste of on-site air source and generation of extra noise

The invention provides a control device for a pneumatic diaphragm pump. The control device comprises a water level sensing mechanism and a control mechanism, wherein the water level sensing mechanism is connected to the control mechanism, and the control mechanism is used for controlling the starting and the closing of the pneumatic diaphragm pump according to a water level sensed by the water level sensing mechanism; when the water level sensed by the water level sensing mechanism is larger than a set water level, the control mechanism controls the pneumatic diaphragm pump to start up; and when the water level sensed by the water level sensing mechanism is smaller than the set water level, the control mechanism controls the pneumatic diaphragm pump to stop. Owing to the technical scheme, the function of automatically starting or stopping of the pneumatic diaphragm pump is realized according to a water level state, so that the waste of a gas source is greatly reduced, the service lives of a diaphragm of the pneumatic diaphragm pump and the whole machine are prolonged, and noise pollution to the ambient condition is reduced at the same time; and the pneumatic diaphragm pump is simple in structure and attractive in the overall appearance.
Description
technical field [0001] The invention relates to the field of engineering machinery, and more specifically, to a control device for a pneumatic diaphragm pump. Background technique [0002] At present, the mining pneumatic diaphragm pump used in the coal industry is mainly used for underground drainage operations in mines. The compressed air circuit connected to it is in a normal state, and the switch of the equipment needs to be controlled manually. Diaphragm pumps are often left unattended, so that the equipment is still running in an anhydrous state, resulting in: on the one hand, the diaphragm of the diaphragm pump operates under no load, reducing the service life of the diaphragm and the whole machine; On the one hand, it has caused unnecessary waste of on-site air sources and the generation of additional noise. [0003] Therefore, it is an urgent problem to provide a control device for the pneumatic diaphragm pump so that the diaphragm pump can be automatically turned ...
