KCB gear pump is a volumetric pump, consisting of two closed space by two gears, pump, front and rear cover, when the rotation of the gear, the gear disengagement side of the volume of the space becomes large small, forming a vacuum, the liquid suction,the gear meshing side of the volume of the space from large to small, and the liquid to squeeze into the pipeline. The suction chamber and the discharge chamber is spaced by two gears meshing line to. The outlet pressure of the gear pump is entirely dependent on the size of the pump source resistance.
Outside the mesh structure of the double
gear pump. A pair of mutually meshing gears and the pump cylinder to be spaced from the suction chamber and the discharge chamber. Gear is rotated, the volume of the suction chamber side of the tooth at the mutually disengaged interdental gradually increased, pressure reduction, the liquid under the pressure differential into the interdental. With the rotation of the gear, an interdental liquid is brought to the discharge chamber. At this time, the the interdental volume of the discharge chamber side at the tooth engagement is gradually reduced, while the liquid is discharged. Gear pump for conveying solid particles, non-corrosive the lubrication liquid viscosity range. Pump flow to 300 m 3 / h, pressure up to 3 × 107 Pa. It is usually used as a hydraulic pump and transport various types of oil. Gear pump is simple and compact structure, easy to manufacture, easy maintenance, self-absorption capacity, flow, pressure pulsation and noise. The gear pump must be equipped with a relief valve to prevent damage to the pump for some reason, such as discharge pipe clogging the pump outlet pressure exceeds the allowable value or the prime mover.
