Mechanical diaphragm metering pump equipment is a motor rotor type positive displacement pump, because its principle is similar to the digestive system, to mechanically transfer steam, solid and liquid. The monopulse delay time probably does not reflect the speed. Compared with the standard 80msec pulse width, it can stimulate the pulse width of the flow detector to increase the pulse width to 300ms. Run the smart switch panel, remove the cover that holds the immovable circuit board, then remove the jumper X-1. This will encourage the extension to allow more time before common faults are indicated.
1, the mechanical dosing pump should be fully clean and tidy before installation, and the filter device should be installed before the flow meter to avoid impurities into the flow meter. In the whole process of dosing metering pump installation, ensure to prevent polluting substances and residues into the flow channel. When the measured liquid has a vapor body, the gas separation equipment should be installed.
2, it should be noted that the oval shaft sleeve of the flow meter must be installed in the leveling part, that is, the vertical bisecting plane of the outer cover. For the accurate measurement of very small flow, the best installation method is the bottom in, the top out. Adjust the flow rate and run, and close the gate valve to install at the import and export trade end of the flow meter.
3. The orientation of the arrow symbol on the flowmeter housing should be consistent with the orientation of the liquid flow in the installed pipeline.
4, in the continuous flow of the pipeline, the degree of installation of the flow meter pipeline should be set an intake valve, which is conducive to timely cleaning and maintenance. The flowmeter in the riser should 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, for circulating cooling water, filtered water, wastewater treatment, laboratory, laboratory and other low environmental pollution liquid dosing.
