What are the confirmation points of the hydraulic pump type?

The following points should be considered when determining the type of hydraulic pump

① Determine the working pressure of the hydraulic system. The low-pressure system below 2.5MPa should use a gear pumps, the medium-pressure system of 2.5-6.3MPa should use a vane pump, the high-pressure system of 6.3-10MPa should use a high-pressure gear pump and high-pressure vane pump, and the high-pressure system above 10MPa should use a plunger pump;

②The load power of the hydraulic system. For hydraulic equipment with small load and low power, gear pumps and double-acting vane pumps can be used; for hydraulic equipment with large load and high power

③Working speed requirements of the system. For equipment with high-speed and stable-speed strokes, such as combined machine tools, etc., in order to make energy utilization reasonable, pressure-limited variable vane pumps and double vane pumps can be used;

④ The stability requirements of the equipment. On special precision equipment (such as mirror grinders, injection molding machines, etc.), in order to reduce vibration and noise, double-acting vane pumps and screw pumps are used. Those systems that do not require high stability, pulsation and noise can use medium and high pressure gears Pump;

⑤ Economy. A cost-effective hydraulic pump should be selected as far as possible according to the equipment requirements, and a low-priced gear pump should be used for mechanical auxiliary devices (such as feeding, clamping, lubrication, etc.); in addition, self-priming ability and anti-pollution should also be considered when selecting a hydraulic pump ability.
