Herringbone tooth has the advantages of straight tooth and oblique tooth, but the shear force is large, which is easy to degrade the material. Therefore, gear should be selected according to the characteristics of materials. Batte's zb-b series gears and bearings are made of chrome nickel alloy and M2 high-speed tool steel; zb-h series are made of imported CPM tool steel or titanium tantalum alloy material, with overall quenching, hardness hrc62-68 and good wear resistance. The melt pump body is made of high-temperature tool steel or stainless steel (special for corrosion resistance), with a hardness of about HRC65, and a smoothness of 0.8 for flow channel and octagonal hole. There are three sealing methods: mechanical seal, mechanical packing seal and mechanical packing cold water triple seal.
