Effect of viscosity on gear pumps
Thread Content
If the viscosity of the oil is less than the required minimum viscosity, what will be the impact on the gear pump? Viscosity affects friction and also affects which aspect of the gear pump operates.
The actual flow rate is smaller than the theoretical flow rate because the volumetric efficiency decreases due to low viscosity and internal leakage increases, but the shaft power also decreases.
If the year is too small, the head of the pump may be reduced.
The viscosity is high, so for gear pumps, it is easy to insufficient suction. The pump is prone to vibration and has low viscosity. For gear pumps, the gear clearance needs to be adjusted, otherwise it will be easy to unload and the pressure will not be pumped up.
Viscosity is a concern. study * Down
Hello, landlord! Your picture is a screenshot from the gear pump instruction manual. When conveying materials lower than 5cst, the actual flow rate will be less than the rated flow rate, and the greater the outlet pressure, the greater the flow attenuation of the pump (internal leakage). Most low-viscosity materials have poor or no lubrication, and the service life of the gear pump will be reduced. If you have any questions about gear pumps, you can leave a message at any time.
Hello, I would like to ask, if the function I want is to close the outlet and increase the speed and pressure, what is the relationship between speed and pressure? Is it a certain number of revolutions per minute that will produce extremely high pressure?
If the viscosity drops too much, will the pump be in harm's way?
