工作唧筒。当增大机床外形轮廓没有关系时,在两方向内以相同的速度直线移动机床的工作部分系采用两面有拉杆的唧筒。移动活塞所必需的油压力为: 活塞速度: 式中:Q──进入唧筒的液量(公斤/分) 在磨床上为了减小外形轮廓,常采用一面有细拉杆的唧筒,在这种情况下,两方向内的移动 Working pump. When increasing the outline of the machine does not matter, the same speed in both directions to move the machine part of the work of the Department of the use of both sides of the rod pump. The hydraulic pressure necessary to move the piston is: Piston Speed: where: Q - the volume of liquid entering the pump (kg / min) on the grinder In order to minimize the profile, a cylinder with a slim drawbar is often used, in which case Next, both inward movement
