Description

Technical Field

[0001] The present application relates to the technical field of diaphragm pumps, and in particular to a detection device for a pneumatic diaphragm pump. Background Art

[0002] The diaphragm pump uses a thin film to separate the pumped liquid from the piston and the pump cylinder, thereby protecting the piston and the pump cylinder. The left side of the diaphragm that contacts the liquid is made of corrosion-resistant materials or coated with a layer of corrosion-resistant substances; the right side of the diaphragm is filled with water or oil.

[0003] Diaphragm pumps, also known as control pumps, are the main type of actuators. They receive control signals from the control control unit and use power to change the fluid flow rate. The role of the diaphragm pump in the control process is to receive control signals from the regulator or computer, change the flow rate of the regulated medium, and maintain the regulated parameters within the required range, thereby achieving automation of the production process. To achieve regulation and control of a certain process parameter such as temperature, pressure, flow, liquid level, etc., a diaphragm pump is indispensable.

[0004] With regard to the above-mentioned related technologies, the diaphragm pump needs to be tested after production or after being used for a period of time to verify whether there are any faults in the various performances of the diaphragm pump. The existing testing equipment is usually a single performance test, and the staff needs to use each device to test in turn, and the testing efficiency is low. Utility Model Content

Then, the suction detection mechanism can detect whether the suction of the diaphragm pump is normal. Then, the placement seat is slid by the sliding cylinder, so that the diaphragm pump is moved to the pipeline detection mechanism to detect whether there is a fault in its pipeline, thereby achieving the purpose of improving the detection efficiency.

[0017] Optionally, an elastic pad with a protective film is provided at the clamping point between the outer frame and the inner frame.

[0018] By adopting the above technical solution, an elastic pad is provided to protect the film, thereby reducing the possibility of the film being worn by the film frame, while improving the installation effect of the film and reducing the possibility of falling off.

[0019] Optionally, the pipeline detection mechanism includes a water inlet and a water outlet, and the water inlet and the water outlet are both provided with a delivery pipe connected to a diaphragm pump.

[0020] By adopting the above technical solution, the diaphragm pump is connected to the water inlet and the water outlet through a delivery pipe, and the diaphragm pump is ventilated and watered from the water inlet respectively to see whether water is discharged from the water outlet, thereby determining whether there is a fault in the diaphragm pump pipeline.

[0021] Optionally, the placement seat is provided with a lifting seat, and a lifting cylinder for driving the lifting seat to rise and fall is provided in the placement seat.

[0022] By adopting the above technical solution, the placement seat is provided with a lifting cylinder to drive the lifting seat to rise and fall, so that the height position of the diaphragm pump can be adjusted, which is convenient for installation and adaptable to diaphragm pumps of more specifications.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The diaphragm pump is placed on the placement seat, fixed by the limit mechanism, and then the suction detection mechanism can detect whether the suction of the diaphragm pump is normal. Then the placement seat is slid by the sliding cylinder, so that the diaphragm pump is moved to the pipeline detection mechanism to detect whether there is a fault in the pipeline, so as to improve the detection efficiency;

[0025] 2. After the diaphragm pump is placed on the placement seat, a clamping cylinder is set to drive the clamping block to descend, so that the diaphragm pump is clamped between the clamping block and the placement seat to achieve position limiting of the diaphragm pump;

[0026] 3. The driving component can control the movement of the film frame so that the film in the film frame moves to the feed port of the diaphragm pump, and the diaphragm pump starts working. If the film is sucked toward the feed port and blocks it, it means that the suction of the diaphragm pump is normal, otherwise the diaphragm pump fails the inspection.
