Chemical vertical pump common sense

Chemical vertical pumps can be divided into submerged pumps, cylindrical pumps and vertical pipe pumps. Submerged pump refers to the pump body can be immersed in the liquid pump. Often installed in the liquid tank. Liquid pump structure type volute, screw-type, turbine and other, can be single-stage, but also multi-stage, depending on head and structure may be. The inlet and outlet of the cylindrical pump are generally taken at the same height, with inner and outer two shells. The inner shell is composed of the rotor, the guide vane and the pump shaft. The outer shell is the inlet diversion channel and the liquid is sucked in from the lower part. Cylinder pump is generally mainly used for liquefied gas, liquefied natural gas and other low temperature medium delivery. Vertical pipe pump structure is very simple, no foot, pump as part of the pipeline, installation without changing the pipeline.

Metal Drilling Drill Bit

Metal Drilling Drill Bits actually is High Speed Steel Twist Drills. The twist drill is the most common type of drill. The shank of the drill is held by the machine tool, which in turn imparts a rotary motion. This shank may be straight or tapered. The body of the drill is typically made up of two spiral grooves known as flutes, which are defined by a helix angle that is generally about 30 degree but can vary depending on the material properties of the workplace. The point of the drill generally form a 118° angle and includes a 10 degree clearance angle and chisel edge .The chisel edge is flat with web thickness of approximately 0.015 x drill diameter. This edge can cause problems in hole location owing to its ability to "walk" on a surface before engaging the workplace. In the case of brittle materials, drill point angles of less than 118 are used, while ductile materials use larger points angles and smaller clearance angles.

Metal Drilling Drill Bit is a kind of cutting tool widely used for metal, like aluminum, alloy, copper, steels, stainless steel, iron, etc.

There are usually the following types of twist drills: Straight Shank Twist Drill Bit, Morse Taper Shank Twist Drill Bit, Reduced Shank Twist Drill Bit, Step Drill Bit , Hex Shank Twist Drill Bit , Three Flats Twist Drill Bit, double ended drill bit.
