The design of low-pressure gear pumps is crucial to the technical development of low-pressure gear pumps
Low pressure gear pump is a commonly used gear pump. Its design is clever and reasonable, easy to use, and has a long life. The production and processing of low-pressure gear oil pumps is very important in the selection of high-temperature industrial pumps.Gear oil pumps are commonly used to deliver highly corrosive, abrasive or volatile fluids.Pump casing, shaft and bearing materials must first match the pumped liquid.When high temperature is considered externally, the design of low-pressure gear oil pumps becomes more complicated, and even the thermal expansion of various materials needs to be considered.Low-pressure gear oil pumps need to consider different quality factors in use, play an important value and performance in talents, and ensure that they can play an important role in the industry. Preheating of the low-pressure gear oil pump is necessary to prevent high-temperature shocks from damaging components.Preheating is recommended when the temperature of the pumped fluid is above 150 ° C.When using a mechanical seal, the gear oil pump must be preheated to within 30 ° C of the operating temperature difference to prevent damage to the sealing surface.Jacketed pump can be preheated by steam, heat medium and electric heating.Viscosity is the resistance to fluid flow. The first problem in high viscosity conditions is how to get the fluid into the pump.The gear oil pump must rotate slowly to allow fluid to enter the unmeshed interdental cavities, which create a suction to draw fluid into the pump.The tighter the clearance, the better the internal seal of the gear oil pump and the stronger the suction force. The design of low- pressure gear oil pumps is very important for the technical development of low-pressure gear pumps.
