● ZYB gear pump uses
ZYB gear pump for conveying solid particles and fibers , non-corrosive, temperature no higher than 180 ℃, the viscosity of 5 × 10-6 ~ 1.5 × 10-3m2 / s (5-1500cSt) of oil or a similar nature other liquid lubricants .
● Applications
Can be used in the oil transfer system, booster pump ;
Used as a transport fuel systems , pressure , fuel injection pump ;
In the hydraulic system used to provide hydraulic power pumps ;
In all industrial areas, can be used as a lubricating oil pump ;
● ZYB structural characteristics of gear pumps
ZYB main gear pump gears, shafts , pump, valve , shaft seal formed . Heat treated gears have high hardness and strength , together with the operating shaft mounted in a replaceable bushings. All parts of the ZYB gear pump lubrication are using the output medium automatically when the pump is working to achieve .
ZYB gear pumps are designed within a reasonable drain and return tank, gear to withstand the torque force at work a minimum , thus bearing loads of small, wear , high pump efficiency .
Pump is provided as overload protection valve , the entire valve return pressure pump rated pressure of 1.5 times to exclude , can be adjusted if needed based on the actual discharge pressure within the allowable range . But note that this safety valve relief valve can not be long-term work , when necessary, be installed in the pipeline .
Overhang from the spindle end to the pump to see , for the clockwise rotation.
