Mechanical diaphragm metering pump equipment is a motor rotor positive displacement pump, which is famous for its principle is similar to that of digestive system, and is famous for mechanically transmitting steam, solid and liquid. Single pulse delay time is likely not to reflect speed. Compared with the standard 80msec pulse width, it can expand the pulse width of the excitation traffic detector and increase the pulse width to 300ms. Run the smart switch panel, remove the cover of the fixed circuit board, and then remove the jumper X-1. This will stimulate speech expansion and allow more time before common fault indication.

1. The mechanical dosing pump shall be fully clean and tidy before installation, and the filter device shall be installed before the flowmeter to prevent impurities from entering the flowmeter. During the whole installation process of dosing metering pump, it is ensured to prevent pollutants and residues from entering the flow channel. When the measured liquid contains vapor, gas separation equipment shall be installed.

2. It should be noted that the oval shaft sleeve of the flowmeter must be installed at the level part, that is, the vertical bisector of the outer cover. For the accurate measurement of ultra-small flow, the good installation method is bottom in and top out. Adjust the flow and operate. When closing the gate valve, it shall be installed at the inlet and outlet ends of the flowmeter.

3. The orientation of the arrow symbol on the flowmeter housing shall be consistent with the liquid fluidity orientation in the installed pipeline.

4. In the pipeline with continuous circulation, the degree of installing flowmeter shall be set with inlet valve, which is conducive to timely cleaning and maintenance. The flowmeter in the riser shall be installed in the bypass pipe to prevent dirt from falling into the instrument panel.

Mechanical diaphragm metering pump equipment is used in food, chemical plants, pharmaceutical industry, biotechnology, paper industry, engineering construction, mining, sewage treatment and other fields to recycle cooling circulating water, filtered water, wastewater treatment, laboratory, laboratory and other low environmental pollution liquid dosing.
