The direction of rotation of the kcb gear pump should be consistent with the inlet and outlet ports. If the kcb gear pump is operated for the first time, or used after a long period of idle, it is best to run for about an hour under no-load or light-load conditions. When abnormal temperature rise, leakage, vibration and noise are detected in advance during the running-in phase, the machine should be shut down for inspection. The support or flange of the kcb gear pump and its drive motor should use a common installation foundation, and the foundation, flange or support must have Sufficient rigidity to reduce the vibration and noise generated by the 2CY gear pump during operation. The motor and the Hon Hai Pumps kcb gear pump must be connected with an elastic coupling, the coaxiality is less than 0.1 mm, and the inclination angle must not be greater than 1 degree. Installation Do not hit the coupling with a hammer to avoid damage to the gears and other parts of the kcb gear pump. When tightening the kcb gear pump and the anchor bolts of the motor, the screw should be evenly stressed and the connection should be reliable. When rotating the coupling by hand, you should I feel that the 2CY gear pump can rotate easily, and there is no abnormal phenomenon such as jamming, and then it can be piping.The inner diameter of the oil suction pipe of the kcb gear pump should be large enough to avoid narrow passages or sharp turns, reduce elbows, and remove unnecessary Valves, accessories, reduce the installation height of the pump as much as possible, shorten the length of the suction pipe to reduce pressure loss. The sealing of pipe joints and other components should be good to prevent air intrusion, so as to control the occurrence of cavitation and cavitation. Valve and safety valve is best to install a check valve on the output pipeline of the kcb gear pump. So that the liquid in the system will not flow back when the pump and the output pipeline are repaired.
enters the oil suction cavity through the oil suction pipe, fills the interdental groove, and as the gear rotates, brings the oil to the left pressure oil cavity.
On the side of the oil pressure zone, as the gear teeth gradually enter meshing here, the volume of the sealed working chamber is continuously reduced, and the oil is squeezed out and is transported from the oil pressure chamber to the pressure pipeline. In the working process of the gear pump. As long as the direction of rotation of the two gears remains unchanged, the positions of the oil suction and discharge chambers are also determined. Here, the tooth surface contact line at the meshing point always separates the high and low pressure chambers, which play the role of oil distribution. It is composed of a pair of gears in the housing. On both sides of the gears are the end cover housing, the end cover and the inter-tooth grooves of the gears to form many sealed working chambers. When the gears rotate in the direction shown in the figure, the oil suction chamber on the right The meshing gear teeth are gradually disengaged, and the sealed working volume gradually increases, forming a partial vacuum. Therefore, under the action of the external atmospheric pressure, the oil in the oil tank enters the oil suction cavity through the oil suction pipe, filling the interdental groove, and following the gear Rotate to bring the oil to the left pressure oil chamber. On the side of the oil pressure zone, as the gear teeth gradually enter into engagement here, the volume of the sealed working chamber is continuously reduced, and the oil is squeezed out from the pressure oil chamber. It is delivered to the pressure pipeline. During the working process of the gear pump, as long as the rotation direction of the two gears is unchanged, the positions of the suction and discharge chambers are determined unchanged. Here, the tooth surface contact line at the meshing point is always separated The high and low pressure two chambers play the role of oil distribution, so there is no need to set a special distribution mechanism in the gear pump, which is the difference between it and other types of positive displacement hydraulic pumps.
