KCB gear pump installation

KCB bearing flange of the gear pump and its drive motor should be used a common mounting base, the base flange or the holder needs to have sufficient rigidity to reduce the vibration and noise generated in the operation of the gear pump. Motor and gear pump shall be connected with a flexible coupling concentricity of less than 0.1 mm, the tilt angle shall not be greater than 1 degree. Install the coupling may not be used hammer, so as not to damage the gear pump gears and other parts. Bracket bearing, drive pulleys, sprockets, etc. should be set to prevent the drive gear bearing by radial force. Fastening gear pump, motor ground screw, screw force should be uniform, reliable connection. Hand rotation coupling should feel the gear pump to be able to easily turn the no abnormal phenomenon clamping, before piping. KCB gear pump suction pipe diameter should be large enough to avoid a narrow channel or a sharp bend, reducing elbow, to remove unnecessary valves, accessories, pump installation height as low as possible, to shorten the length of the suction pipe to reduce the pressure loss . Pipe joints and other components of the seal to prevent ingress of air, thereby controlling the occurrence of cavitation and cavitation.

    Before starting the operation, high viscosity pump, filled with the liquid to be conveyed to the gear pump housing, easy and safe start. If the ambient temperature is below freezing, the gear oil pump pass into the hot steam, preheating before starting the gear pump. The direction of rotation of the gear pump into the line, the oil port. Gear pump If this is the first time you run or long-term idle before use, it is best to start and unity hour or so in the case of no-load or small load. If the running-in stage pre-aware of an abnormal temperature rise, leakage, vibration and noise, you should stop to check.

    The non-return valve and safety valve gear pump output pipeline is best to install a non-return valve. This access to the pump and output pipe, the liquid does not occur in the system back. Can also prevent the pump from reverse gear pump with a load stop, a partial vacuum in the output pipe. It should be noted that the outlet check valve can not be installed anti-or stuck. KCB gear pump discharge piping should also set the safety valve protection device, so that once the pump outlet channel clogging, you can open the safety valve relief. The safety valve can be molded integrally with the pump or the pump cover can also be fitted separately. KCB gear pump for reversing its import and export pipeline are required to set safety valve.
