The theoretical flow Qr of the
stainless steel gear pump has nothing to do with the pipeline characteristics, but only depends on the pump itself, while the pressure index provided is determined by the pipeline characteristics and has nothing to do with the pump itself. When the discharge pressure of the gear pump increases, the leakage loss in the pump increases, so the actual flow rate of the pump decreases slightly with the increase of pressure.
The shaft power of stainless steel gear pump increases with the increase of discharge pressure, and the efficiency of the pump also increases, but when the pressure exceeds the rated value, the efficiency will decrease due to the increase of leakage in the pump.
With the increase of liquid viscosity and gas content, the flow rate and efficiency of stainless steel gear pump decrease.
Stainless steel gear pump must be equipped with safety valve.
The flow rate of stainless steel gear pump can not be adjusted by outlet valve, and the method of bypass regulation and speed regulation is often used to adjust the flow rate.
The stainless steel gear pump does not need to be filled before starting, but the valve must be opened before starting.
Stainless steel gear pump is often used to transport non-corrosive oil and other viscous media, but not suitable for conveying liquids containing solid particles and liquids with high volatility and low flash point.
