Points to pay attention to when purchasing arc gear pumps. The first consideration of arc gear pumps is to transport liquid. Because arc gear pumps rely on the extrusion of gears to continuously output liquid, it will generate a lot of pressure. The maximum can reach 1.6MPa, or even larger. The arc gear pump can transport lubricating liquids, such as lubricating oil, diesel oil, crude oil, etc. But it should be noted that water must not be pumped, because water has no lubricating function. Pumping water will cause the gears to get stuck and the motor to burn out. For liquids with low flash points, such as benzene, gasoline, etc., copper gears must be used, because if cast iron or stainless steel is used, sparks will be generated during the rotation of the gears, then would cause great danger.
Arc gear pumps have very high requirements on temperature. Generally, the temperature of the medium should not exceed 80 degrees. Choose a thermal oil pump or a heat conduction oil pump. For thicker oils, the maximum viscosity is 500c.s.t. If the viscosity exceeds this viscosity, the liquid must be heated, or a high-power motor should be replaced to avoid burning the motor. For liquids with weak corrosive media, gears As long as the pump is equipped with stainless steel, it can still complete the work.
Therefore, the circular arc gear pump has powerful functions, and the use of different materials can expand its range of use and efficacy. Especially for flow and pressure, with different motors, different inlet and outlet diameters, and materials, it can reach a maximum diameter of 10 inches. 5400L.
