Problems solved by technology
[0006] The present invention designs a method and device for detecting the displacement and replenishment of propellant in a piston diaphragm pump. The technical problem it solves is that when the piston diaphragm pump is operated for a long time, the detection signal will fail due to the continuous entry of dust and other impurities. In severe cases, it will cause Diaphragm rupture and other larger effects

Embodiment Construction
[0020] Combine below figure 1 , the present invention is further described:
[0021] A device for detecting the displacement and replenishment of propellant in a piston diaphragm pump. A multi-fluid detection probe 1 and a low-fluid detection probe 2 are arranged on the piston diaphragm pump. 1 and the low-liquid detection probe 2 , the detection magnet 3 is arranged outside the piston diaphragm pump and is also located between the multi-liquid detection probe 1 and the low-liquid detection probe 2 .
[0022] The working principle of the detection piston diaphragm pump discharge and replenishment propellant device is as follows:
[0023] Under normal working conditions, the detection rod 5 moves between the excess liquid detection probe 1 and the low liquid detection probe 2 without triggering a signal;
[0024] Or, if the propelling liquid in the propelling liquid chamber is too little, the detection rod 5 triggers the low liquid detection probe 2 to generate a pulse signal...

The invention relates to a method and a device for detecting the pushing liquid discharge and supplement of a piston diaphragm pump. A sufficient liquid detection probe and an insufficient liquid detection probe are arranged on the piston diaphragm pump; a detection rod is positioned in a pushing liquid chamber, and the end of the detection rod is positioned between the sufficient liquid detection probe and the insufficient liquid detection probe; and a detection magnet is arranged outside the piston diaphragm pump and positioned between the sufficient liquid detection probe and the insufficient liquid detection probe. The detection magnet is arranged, so whether an oil discharge or supplement signal exists or not can be quickly detected, and a fault is quickly and timely removed.
Description
technical field [0001] The invention relates to a method and a device for detecting the displacement and replenishment of propellant of a piston diaphragm pump. Background technique [0002] For pumping highly concentrated slurries, sludge or tailings, piston diaphragm pumps are best used. The pump seals against abrasive material from the piston through a hydraulically actuated diaphragm, which can be controlled in either direction of stroke by filling or draining propellant fluid in the cavity between the piston and diaphragm. [0003] Specifically, there are corrosive materials and propellant fluid on both sides of the diaphragm, and the diaphragm is kept balanced by being squeezed by the material and the propellant fluid simultaneously, so as to ensure that the material has no contact with moving parts such as pistons, piston rods or piston cylinders. [0004] But this kind of piston diaphragm pump itself also has a defect: when the piston diaphragm pump is running for a...
