Stainless steel gear pump is a pump, there are gears, shaft, pump, safety valve, shaft seal composition. It is mainly used in small flow, high head of the water system, the gear after heat treatment has a higher hardness and strength, together with the shaft installed in the sleeve can be replaced within the operation.
In the drinking water supply system, pressure boiler water supply system and medicine, food, paper and other industries widely used. Stainless steel gear pump generally do not have lubrication, it is in the output medium at the same time can automatically reach a certain lubrication requirements.
Gear pump has a reasonable design of the oil drain and back to the oil tank, which bear the torque is very small, so this pump bearing load is very small, wear is also small, the pump efficiency is high. Although there is a safety valve in the pump body as overload protection, but in the course of the application still pay attention to the pump point pressure and stroke frequency, especially the corrosive medium.
Stainless steel gear pump gears are the most common straight teeth, helical teeth, herringbone teeth, spiral teeth. There are two main tooth profile, one is involute tooth profile, a circular tooth profile.
Under normal circumstances, the use of small gear gear involute gears, gear pumps often use high-temperature gear, if the high viscosity of the transfer, the more involute helical gears.
Gear and shaft made of one, its rigidity and reliability than gear and shaft manufacturing gear pump alone, to increase the bearing chamber third advantage, large stent cavity to provide space does not require removal of the pump can be adjusted on the filler, Important parts can also be based on their work requirements and process needs to be replaced with high temperature, wear resistance, corrosion resistance, high pressure resistant material.
The structure of the pump body also avoids the imperfect sealing phenomenon caused by the vibration, which ensures the stability of the pump conveying medium. The gap between the gear tail can also be adjusted, NYP high viscosity gear pump according to the viscosity of the transmission medium, by adjusting the gear gap to the pump at different viscosity of the process requirements, simple operation.
