Gear pump heating method

Equipped with a pair of rotary gear pump gear pump, an active, a passive, relying on mutual engagement of the two gears, the pump within the entire working chamber is divided into two independent parts. A suction chamber, B is the discharge chamber. Pinion gear pump when in operation driven by the driven gear to rotate, when the gear is disengaged from the engagement to the suction side when the partial vacuum is formed, the liquid is sucked. Is sucked into the liquid filled gear tooth valley brought to the discharge side, the liquid is squeezed out in the gear into engagement, forming a high pressure liquid, and is discharged through the pump outlet to the outside of the pump.

Gear pump features:
A compact structure, convenient use and maintenance.
Has good self-priming, so every time without poured liquid pump before opening.

Heavier kcb gear pump pump casing, its temperature resistance, higher compressive strength. Pump body material is often used ductile iron, also using a hard mold casting made ​​of cast aluminum alloy, or the use of extruded aluminum profiles manufacturing. When conveying a corrosive medium, may be the higher cost of stainless steel material. The foreign high viscosity gear pump to use more nickel, high chromium alloy steel pump casing material, the better overall performance of this material strength, reliability and cost. In order to solve the difficulties of gear oil pump oil phenomenon, usually in the pump cover open symmetrical unloading slot, or opened to the low pressure side of the direction of asymmetry unloading tank, the suction side of a tapered unloading tank drain side of the rectangle unloading Dutch the depth of the grooves unloading groove to be deeper than a gear pump used in the hydraulic industry.
