Weidron pump for you to explain the principle of cycloid pump structure

Rotor pump, we often see in everyday life Oh, then we all know that the cycloid gear pump, cycloidal gear pump some of the structural principle? The following Weidelong pump for you to explain simple cycloid pump structure principle! The cycloidal rotor pump is a kind of special internal gear oil pump. The main features of the cycloidal rotor pump are its compact structure, few parts, small flow pulsation and low noise. The disadvantages of the cycloid rotor pump are high machining precision, poor workmanship and difficult to seal, Low volumetric efficiency. Schematic diagram of the cycloidal rotor pump structure, the pump from the inner rotor l, the outer rotor 2 and with the flow plate and the side plate and other components. a, b for the distribution plate with the oil window. The gerotor of the rotor in the cycloidal rotor pump is a cycloid (external gear), the tooth shape of the outer rotor is an arc, and the two kinds of teeth are a pair of conjugate curves. The number of inner rotor teeth is Z1 and the number of outer rotor teeth is Z2 = z1 + 1, which forms z2 sealed spaces with the distribution plate and the side plates. O1O2 3 = eo When the inner rotor rotates clockwise around o1, it drives the rotor to rotate in the same direction around 02. At this moment, the volume c of the sealed working space formed by the inner rotor top A z and the outer rotor valley A1 becomes larger Figure l-12b part of the sun), the formation of a partial vacuum, the oil flow through the plate window b suction Ao rotor rotation to Figure l-12h position, the maximum volume of sealed space, and then continue to rotate, then the smaller the volume of sealed space , The oil is squeezed out of the window of the adapter plate. When the cycloid pump outer rotor turn a week, each sealing space in turn suction liquid discharge once.

Fiberglass Mesh

Fiberglass mesh is made by soaking and coating with macromolecular alkali-resistant latex on the basis of C-fiberglass and E-fiberglass. The color of fiberglass mesh is white, black, organge, blue, yellow or as per customer's needs. And the fiberglass mesh's package can also as per customer's requirement to finish. The fiberglass mesh be widely used on : wall reinforcement, reinforced cement products, waterproofing favrics, the roof waterproof, enhance the skeleton of plastic and rubber, fire prevention board, highway parements, joint tapes of buildings.

The advantages of fiberglass mesh:

high strongth

good alkali resistance

prevent cracks and deformations

easy to be constructed

more durable
