Gear pump mainly gear, shaft, pump body, safety valve, shaft seal composed of the end. The gears are heat-treated to a higher hardness and strength and mounted with the shaft in a replaceable hub. The lubrication of all parts in the pump is automatically achieved using the output medium while the pump is in operation. Gear pump has a well-designed drainage and oil return groove, the gear in the work to withstand the torque of the smallest, so the bearing load, wear small, high pump efficiency. Gear pump with safety valve as overload protection, safety valve full back pressure of the pump rated exclusion pressure of 1.5 times, but also allow the discharge pressure within the scope of the actual need to be adjusted. But note that the safety valve can not be used for long-term work of the valve, if necessary, can be installed separately in the pipeline. The use of large flow gear oil pump: Suitable for conveying non-solid particles and fibers, non-corrosive, the temperature is not higher than 80 ℃, the viscosity of 5 × 10-6 ~ 1.5 × 10-3m2 / s (5-1500cSt) lubrication Oil or other liquids of similar lubricating properties Applications of high flow gear oil pumps: Used as a transmission, booster pump in a fuel delivery system, as a fuel pump for delivery, pressurization, injection in a fuel system All industrial areas, can be used for lubricating oil pump. Large flow gear pump structure features: This series gear pump mainly gear, shaft, pump body, safety valve, shaft seal composed of gear by heat treatment with high hardness And strength, installed in the shaft with the replacement of the sleeve operation. Pump lubrication of all parts are used in the pump output medium and automatically use the pump has a well-designed pump drain and return tank, the gear at work In the torque to bear the smallest, so the bearing load, wear small, high pump efficiency.
