YCB series arc gear pump common material and stainless steel difference YCB series ordinary material arc pump for conveying solid particles and fiber-free, non-corrosive, the temperature is not higher than 200 ℃, the viscosity of 5 × 10-6 ~ 1.5 × 10-3m2 / s (5-1500cSt) of lubricating oil or other liquids with similar properties; if used in petroleum, chemical, metallurgical, mining, power plant and other sectors of the transfer of oil media, pressurized, fuel injection, etc. and Large-scale machinery and equipment in the thin oil circulation, in all types of machinery and equipment can be used as a lubrication pump. In the oil transfer system can be used as transmission, booster pump; In the fuel system can be used as transport, pressure, jet Fuel pump; in all industrial fields, can be used for lubricating oil pump YCB series stainless steel gear pump for conveying solid particles and fibers, corrosive; the same time, YCB series gear pump can be used with copper gear mechanical seal assembly, It is mainly used to transport flammable and inflammable medium such as gasoline, diesel oil, toluene, etc. in volatile flammable and explosive occasions.The circular arc gear pump adopts the most advanced continuous contact gear which is regarded as the most advanced pump in the world, Composite sinusoidal tooth profile can be Bottom out involute gear pump. Won the national major scientific and technological achievements project, and by the State Education Commission science and technology progress prize three. Arc gear pump gear in the two meshing tooth profile for a little continuous contact, will not produce trapped oil phenomenon , Completely solve the involute gear pump (KCB series belong to the involute gear pump) due to oil trap phenomenon caused by pump vibration, noise, bearing load increases, etc. Therefore, arc gear pump with low efficiency, low noise, and has Good energy-saving effect.This series arc gear pump mainly consists of gear, shaft, pump body, pump cover, bearing sleeve, shaft end seal, etc. The gear is made of double circular arc sinusoidal tooth profile, which is connected with involute gear phase Than the most prominent advantage is that the gear meshing process tooth surface is not relatively sliding, so the tooth surface wear-free, smooth operation, no fluid due to the phenomenon of low noise, long life, high efficiency. The pump out of the shackles of traditional design, making Circular arc gear pump in the design, production and use into a new field. Pump has a safety valve as overload protection, safety valve full back pressure pump rated discharge pressure of 1.5 times. Can also be allowed within the discharge pressure range according to The actual need another But pay attention to the safety valve can not be used for long-term work of the valve, if necessary, can be separately installed in the pipeline pump shaft seal designed in two forms, one for the mechanical seal, one is the packing seal, according to the specific Use and user requirements to determine from the spindle extension to the pump to see, clockwise rotation.
