Three screw pump advantages and strengths

The characteristics of three screw pump 1, the stator and rotor contact screw seal line income chamber and the discharge chamber is completely separated, so that the pump has the role of the valve partition; 2, liquid, gas, solid multiphase mixed transmission; 3, the pump The inner volume of fluid does not change, there is no Swiss flow agitation and pulsation; 4, elastic stator volume chamber can effectively reduce the delivery of solid particles containing medium wear; 5, the input medium viscosity up to 50000Mpa · s solid The amount of up to 50%; 6, flow and speed proportional to the amount of automatic adjustment with the governor pump can be positive and negative transport. Three screw pump has the following advantages: 1, compared with the centrifugal pump without the need to install the valve flow rate is not chaotic linear activity; 2, and pump piston pump with self-absorption ability, high suction height; 3, and the diaphragm Pumps can pump a variety of mixed material mixed with impurities containing gas and solid particles or fibers of the medium, but also convey a variety of aggressive substances; 4, and gears, three screw pump can deliver high viscosity substances; 5, and the plunger Pump, diaphragm pump and gear pump is different, the screw pump can be used for filling and metering pharmaceuticals. : Three screw pump products three screw pump information

Aluminum Die Casting

Die casting(aluminium die casting) is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter and tin based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.

The casting equipment and the metal dies represent large capital costs and this tends to limit the process to high volume production. Manufacture of parts using die casting is relatively simple, involving only four main steps, which keeps the incremental cost per item low. It is especially suited for a large quantity of small to medium-sized castings, which is why die casting produces more castings than any other casting process.[1] Die castings are characterized by a very good surface finish (by casting standards) and dimensional consistency.

Two variants are pore-free die casting, which is used to eliminate gas porosity defects; and direct injection die casting, which is used with zinc castings to reduce scrap and increase yield.
