YCB arc gear pump adopts internationally the most advanced pump that continuous contact with a little gear, double arc plus sinusoidal compound into a tooth shape, can be completely eliminated involute gear pump. Circular arc gear pump in the meshing between the two teeth for a little continuous contact, will not produce trapped oil phenomenon, completely solve the involute gear pump oil pump phenomenon led to vibration, noise, bearing load increases, etc. Therefore, YCB Stainless steel arc pump junction with efficiency, low noise, and has good energy-saving effect. Users in the economic conditions permitting arc gear pump can be considered, it is suitable for conveying viscosity of 5 × 10-6 ~ 1.5 × 10-3m2 / s (5-1500cSt), the temperature below 200 ℃ lubricating oil. YCB series stainless steel arc gear pump scope of application. After the initial determination of the use of arc gear pump, to further determine his seal: one for the mechanical seal steel, one is a high temperature packing seal, according to the specific use of the user to determine. YCB stainless steel arc pump with safety valve as overload protection, safety valve full back pressure of the pump rated discharge pressure of 1.5 times. Can also be allowed to discharge pressure within the scope of the actual need to be adjusted. But note that the safety valve can not be a long-term work of the valve, if necessary, can be installed separately in the pipeline. In terms of material, arc gear pump can be ordinary cast steel, tin bronze impeller material, stainless steel corrosion-resistant material. Equipped with copper gear can deliver low-point liquid, such as gasoline, benzene and so on. In addition to this series of pump configuration common motor, but also according to user needs with the specifications of the explosion-proof motor configuration. Hope that users can rely on the arc gear pump mechanical properties and working environment to select arc gear pump.
