Variable displacement piston pump is a motor as a power source, driven by the drum gear coupling reducer rotation, then what are the advantages and disadvantages of the pump in actual use? Here is the variable piston Introduction to the advantages and disadvantages of the pump. Variable piston pump advantages and disadvantages Introduction First, the advantages of variable piston pump 1. High parameters: high rated pressure, high speed, pump drive power; 2. High efficiency, volumetric efficiency of about 95%, the total efficiency of About 90%; 3. Long life; 4. Convenient variables, many forms; 5. The unit power of light weight; 6. Piston pump parts are subject to compressive stress, material strength and performance can be fully utilized. Second, the shortcomings of the variable piston pump 1. Structure is more complex, the number of parts more; 2. Self-absorption is poor; 3. Higher manufacturing processes, the cost is more expensive; 4. Oil on the more sensitive to pollution, The filtration accuracy, high requirements for the use and maintenance.
