Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic pumps, in particular to an electromagnetic pump with a special-shaped positioning structure. Background Art

[0002] Metering electromagnetic pump, also known as electromagnetic metering pump or electromagnetic diaphragm metering pump, is a device that uses electromagnetic push rod to drive the diaphragm to reciprocate in the pump head, thereby causing changes in the volume and pressure of the pump head cavity. This change further leads to the opening and closing of the suction valve and the discharge valve, realizing the quantitative suction and discharge of liquid.

[0003] The existing electromagnetic pumps are equipped with a bleed overflow valve on the hydraulic end. The valve group has the functions of safe overflow and emptying. Due to the high precision and small flow requirements of this type of pump, any stroke or instantaneous volume loss during the stroke will cause injection medium errors. Therefore, the pump chamber must be fully emptied to prevent the filling flow channel from being affected by air resistance.

[0004] The hydraulic end on the existing metering electromagnetic pump is fixed to the housing of the electromagnetic pump by screws. When installing the hydraulic end, the staff needs to manually position it. This positioning and installation method is inefficient and the accuracy cannot be guaranteed. It also cannot avoid the angular error caused by the fastener installation through hole. It is difficult to balance accuracy and efficiency during the installation process of the hydraulic end.
