我厂生产的MMB1420精密外圆磨床的液压传动系统使用螺杆泵,其作用是利用螺杆的旋转运动,使被排送的液体好象“液体螺母”一样,顺着螺杆上的螺旋槽不断地前进,从而达到输送液体,并对液体进行增压。螺杆泵由于其结构简单,体积小,噪音低,工作平稳,寿命长等优点,正逐渐地得到广泛应用。我厂制造的螺杆泵规格如下; I plant MMB1420 precision cylindrical grinding machine hydraulic drive system uses a screw pump, its role is to use the rotational movement of the screw so that the liquid is discharged as “liquid nut”, along the spiral groove on the screw continue to move forward , So as to achieve the delivery of liquid, and to pressurize the liquid. Screw pump due to its simple structure, small size, low noise, stable work, long life, are gradually being widely used. I plant manufactured screw pump specifications are as follows;
