High pressure gear pump with compact structure, good self-absorption, high efficiency, adaptability and other characteristics, the delivery of liquid containing impurities in the occasion, the pump life than the average gear pump 2-10 times longer. The following small series to introduce you to the pump's basic performance parameters. Basic performance parameters of high-pressure gear pump Introduction High-pressure gear pump (or hydraulic motor) common in the use of the basic performance parameters are: working pressure P, P (dimension Pa or 10_5bar), the flow Q (1 / rain) q (ml / r), power N (kw), torque (n · m), speed n (nad / s; rpm or r / min) For a high-pressure gear pump, the input energy is in the form of the product of torque and rotational speed (M · ∞). The output energy is in the form of the product of the oil pressure and the flow rate (1lp PQ). For the hydraulic motor, the opposite is true. When high-pressure gear pumps or hydraulic motors have no energy loss during their energy conversion, their power expressions will be N = M · ∞ or N = p Q. Working pressure High pressure gear pump working pressure refers to its output pressure. That is, the fluid must overcome the resistance (including the pipeline resistance, the frictional resistance of the moving parts and the applied load, etc.) that must be set up. Resistance increases, the pressure increases I On the contrary, the pressure decreases. This means that the working pressure of high pressure gear pump depends on the size of the external load. In the high-pressure gear pump manual, there are two general provisions of the pressure, namely: the rated pressure and maximum pressure. Rated pressure is to ensure that the volumetric efficiency of the pump, life and rated speed under the premise of continuous operation of the pump allowed to use the maximum pressure over this value is overload. The maximum pressure is the limit pressure that the pump is allowed to overload in a short time, which is mainly determined by the sealing performance and part strength. The rated pressure and the maximum pressure are not the pressure of the actual work of the pump, be careful not to be confused. Due to the different uses of the hydraulic system, the required hydraulic pressure is different, and the pressure is often divided into five levels: low pressure (less than 25 bar), medium pressure (25 to 80 bar), medium to high pressure (80 to 160 bar) , High pressure (160 ~ 320 bar) and extra high pressure (more than 39bar).
