Abstract

The invention relates to a mechanical diaphragm metering pump facilitating outlet pressure increase. The mechanical diaphragm metering pump comprises a pump head, a pump head seat, a transmission box,a driving motor, a diaphragm, a piston rod, a middle section, an inlet one-way valve and an outlet one-way valve, the edge of the diaphragm is clamped between the pump head and the middle section, the middle of the diaphragm is fixed between a closure nut and a supporting nut, the supporting nut is connected with the piston rod, the closure nut is positioned on one side, contacting with a conveying medium, of the diaphragm, the supporting nut is positioned on one side, not contacting with the conveying medium, of the diaphragm, and a movable supporting semi-ring component for supporting the diaphragm is arranged on the supporting nut. Compared with the prior art, the mechanical diaphragm metering pump is convenient to maintain and simple to use, a specially designed movable supporting semi-ring is mounted in the mechanical diaphragm metering pump, so that the static pressure of the mechanical diaphragm metering pump is multiply increased, maximum working pressure is improved by eighttimes, so that the mechanical diaphragm metering pump meets a novel process in the fields of water treatment and chemical addition.

Description

technical field [0001] The invention relates to a mechanical diaphragm metering pump, in particular to a mechanical diaphragm metering pump with increased outlet pressure. Background technique [0002] The mechanical diaphragm metering pump is a special positive displacement pump that can meet the needs of various strict technological processes. The flow rate can be adjusted steplessly within the range of 0-100%. It is used to transport liquids (especially corrosive liquids). [0003] Due to its relatively low cost, simple structure and convenient maintenance, mechanical diaphragm metering pumps are widely used in the water treatment industry and some chemical fields. In recent years, due to the rapid development of the market and the improvement of some processes, the requirements for mechanical diaphragm metering pumps Higher and higher. [0004] Chinese patent CN202789454U discloses a conventional mechanical diaphragm metering pump, which includes a sequentially connecte...
