Do you understand the working principle of metal lobe pump

Metal lobe pumps are mainly composed of a pump chamber, an intermediate isolation chamber and a synchronous gear chamber, in which two rotors rotating in opposite directions are installed to convey the medium. The middle isolation chamber is used as a barrier to isolate the pump chamber and the synchronous gear chamber, and is mainly used to lubricate the mechanical seal and detect the failure of the machine seal. When the mechanical seal fails, the medium will flow into the intermediate isolation chamber and finally flow out from the top of the intermediate isolation chamber to the outside of the pump chamber to prevent the medium from entering the synchronous gear chamber and then wear or damage the gears. Two pairs of gears with the same number of teeth, as well as high-strength bearings, shaft seals and other transmission components make up the synchronous gear cavity, which is filled with lubricating oil to lubricate the gears and reduce the temperature. According to the name, the lobe pump is a kind of equipment that can be rotated, mainly for transporting liquids, and its volume is very small. Although the volume is small, but according to different criteria, can be divided into many types, each kind of lobe pump is applicable to a different range. Having said that, how many people understand its working principle? In industrial production, centrifugal pumps account for about 80% of the total number of pumps, and lobe pumps account for about 10%. Therefore users are generally more familiar with centrifugal pumps and preferences. This often results in the use of centrifugal pumps in some occasions that are not suitable for the use of centrifugal pumps. Generally speaking, for a variety of different viscosity of the liquid transport, has the advantages of other pumps *, but in the liquid transport, not only the viscosity of the problem, and often accompanied by high temperature, high pressure and sometimes corrosive, or contain solid particles. In the working process is actually through a pair of synchronously rotating rotors. The rotor is driven by a pair of synchronous gears in the box, and the rotor is driven by the main and secondary shafts to rotate in the opposite direction synchronously. This causes the volume of the pump to change, thus constituting a higher vacuum and discharge pressure.
