summary
The herringbone gear not only has the advantages of helical gears, but also overcomes the disadvantage of helical gears generating large axial forces. The company has designed and developed the RCB series herringbone gear pump based on herringbone gear transmission. The RCB herringbone gear pump developed has a point continuous contact between the tooth profiles of two gears during meshing, which does not cause oil entrapment and solves the problems of pump vibration, noise, and increased bearing load caused by oil entrapment in gear pumps. Therefore, RCB herringbone gear pump has the advantages of high efficiency and low noise; Has good energy-saving effect.
RCB herringbone gear pump is mainly used for conveying high viscosity lubricating liquids. The viscosity value of the conveying medium is 3.0-760mm/s. Often used as a delivery pump for asphalt, heavy fuel oil, heavy gear oil, and heavy diesel oil. And it has the following advantages:
1. Compact structure: Under the same flow rate, the RCB herringbone gear pump can be made smaller in size due to the large helix angle of the gears, making the structure more reasonable and compact.
2. Stable operation and low noise: The meshing of RCB herringbone gear pump gears is a smooth meshing, so the pump rotates smoothly with low noise during operation.
3. Self protective function: In case of system problems or oil blockage, the pump itself is equipped with a safety valve, which can directly reflux the medium discharged by the pump to the low-pressure side, thus protecting the pump and system from damage due to excessive pressure.
4. Long service life: Due to the special structural form of the herringbone gear pump, the pump experiences less fatigue load during operation, thereby increasing its service life.
