What is a positive displacement pump? Positive displacement pump refers to the use of pump cylinder volume changes to transport liquid pump. Such as reciprocating pumps, rotor pumps and so on. Reciprocating Pump: Reciprocating pump is the use of reciprocating piston to transport liquid pump, reciprocating piston will be the energy directly to the form of hydrostatic energy transfer liquid. Because the fluid is incompressible, the liquid can be subjected to high pressures as it is pumped to the piston, resulting in a high head. Rotor pump: The rotor pump consists of a stationary pump casing and a rotating rotor. It has no suction valve or discharge valve. The side of the pump body in contact with the liquid acts directly on the liquid as static pressure and rotates the rotor The squeezing action drains the liquid while leaving space on the other side to create a low pressure that allows continuous fluid intake. Rotor pump head pressure is higher, the flow is usually smaller, uniform discharge, suitable for conveying high viscosity, lubricity, but does not contain solid particles of liquid. Types of gear pumps, screw pumps, vane pumps, flexible impeller pumps, Roots pumps, rotary piston pumps, gear pumps and screw pumps which are the most common rotor pump.
Mirror Aluminum Composite Panel
Mirror Aluminum Composite Panel is made up of three layers, with two layers of aluminum skin on the top and bottom, and one layer of non-toxic polyethylene material in the middle.Aluminum composite panel price board also depends on the surface treatment process.
Mirror aluminum sheet made by the rolling, grinding and other methods to deal with the surface of the plate to show the mirror effect.
Generally used rolling method to manufacture the coil material and sheet metal in the aluminum mirror sheet . Mirror appearance performance and ductility are the spectacular highlights and characteristics of the application.
