Metal lobe pumps have an irreplaceable role in the automation of food production

Metal lobe pump is a volumetric pump whose rotor is shaped by a combination of several evenly distributed tooth lobes. The lobe pump operates by means of the periodic transformation of multiple fixed volume delivery units in the working chamber to achieve the purpose of transporting the medium. The mechanical energy of the engine is directly transformed into the pressure energy of the conveyed liquid through the pump. The flow rate of the pump depends on the value of the change in the volume of the working chamber and its frequency of change per unit time, and is (theoretically) independent of the discharge pressure. As the lobe pump is a volumetric pump, it has a very strong material transfer capability. In principle, as long as the medium can flow into the pump cavity, the lobe pump is able to transfer it and has a very wide range of application prospects. But the lobe pump compared to centrifugal pumps, manufacturing costs are much higher, in the transport of relatively low viscosity materials, there is no good cost performance, so in the transport of low viscosity materials, should not choose the lobe pump. lobe pump in the process of conveying materials has a very good inclusion, the physical properties of the material is very small, will be zui to a large extent to maintain the thermal stability of the material. lobe pump can also increase the protection of material performance by increasing the number of teeth lobe and reducing the output speed measures. Thus, the lobe pump is the material of the universal transfer pump reputation. Its main features are as follows: Metal lobe pump has a constant output flow: Under certain conditions of operating frequency, the output flow of a lobe pump is constant: From the working principle of a lobe pump, the output flow of a lobe pump depends only on the volume of its working chamber and its operating frequency. A lobe pump factory working chamber volume is actually determined, can affect its flow rate only its working frequency; and (theoretically) with the discharge pressure has nothing to do, and with the temperature, viscosity and other physical and chemical properties of the transport medium (liquid) (in fact, due to the nature of the medium and discharge pressure is different, the internal leakage between the pump working chamber is also different, the impact on the flow of the pump is also great). When the pump rotation frequency per minute is certain, the flow rate of the pump is also constant. The pressure of the lobe pump depends on the pipeline characteristics: the output pressure of the lobe pump cannot be set by the pump itself, but depends on the pipeline characteristics of the pump unit, and has nothing to do with the flow rate. That is to say, the output pressure of the lobe pump is generated by the resistance on its pipeline, and the pump itself does not generate pressure. The lobe pump has strong adaptability to the conveyed medium (liquid): the lobe pump can in principle convey any medium, almost regardless of the physical or chemical properties of the medium, so we sometimes also call the lobe pump a universal transfer pump. Of course, in the actual application, sometimes encounter can not adapt to the situation. However, when encountering this situation, most of them are because the pump manufacturing materials and manufacturing process and sealing technology can not be solved for a while. The yogurt, syrup, chocolate, peanut butter, ketchup, shampoo, shower gel and other such relatively viscous materials encountered in our daily life are conveyed by metal lobe pumps in the production process. And lobe pumps can also convey materials with poor fluidity like moon cake filling and minced meat, which are irreplaceable for the automation of food production.
