Roots flowmeter(also known as gas waist flowmeter) looks bulky, but it is a very precise measuring instrument. Because its size is larger than that of a general flowmeter, many people do not see its advantages, but it is still one of the most precise instruments available today.

Product introduction of Roots flowmeter: good rotor consistency and symmetry, good repeatability. Even under conditions of significant flow rate variation, it can maintain measurement accuracy. It has a small starting flow, low pressure loss, and a large range, making it suitable for measuring small flow rates. Special process treatment makes the flowmeter operate more stably and have a longer service life. Made of aluminum, it is small in size, lightweight, and easier to install and maintain. Advanced microcomputer technology and high-performance microchips further enhance the overall functionality and performance of the machine. The intelligent integrated design dynamically detects the temperature and pressure of the medium, performs automatic calibration and compressibility correction, and directly displays the standard instantaneous volume flow rate and standard total volume of gas. By combining RS485, RS232C, and MODBUS protocols with a dedicated MODEM, an automatic reading management system is constructed through the telephone network, achieving a high degree of automation.

In response to this situation, in order to overcome the defects of existing technology, today we introduce a nationally approved utility model patent for external gas bearings.Roots flowmeter.

The technical solution of this utility model includes a flow accumulation instrument, a bracket, and a Roots flow sensor, which is equipped with a pair of waist wheels. The rear part of the Roots flow sensor is equipped with a rear cover component, which includes a cover and a rear cover. The cover has a pair of waist shafts, each driven by a pair of waist wheels. There are two waist shafts that engage with each other through synchronous gears. The shape of the waist end face consists of multiple arc tangents, and there are drainage channels on the left and right sides of the long axis diameter of the waist.

Other settings of the Roots flowmeter include: an external end mounting groove corresponding to the waist shaft is set inside the rear cover, and the external end position of the hub is set to be placed together with the external bearing arrangement in the external bearing chamber. The external bearing is placed in the external bearing chamber, and the external end of the external bearing is fixed by a bearing cover.

This utility modelRoots flowmeterhas the advantages of: drainage channels set on the waist wheel, reducing the possibility of rotor jamming, improving reliability, breaking the traditional built-in mode of synchronous gear end bearings, and setting external bearings on the outside of the waist shaft, allowing for bearing replacement without disassembling the synchronous gears. This way, the relative position of the two synchronous gears remains unchanged, the synchronous gears are not damaged, and replacement is convenient.
