机床进行金属切削时,刀具和金属加工件会产生高温发红,这就需要用冷液来冷却。目前多数采用电动机带动,离心泵或齿轮泵供液冷却。我厂在各级党委领导下,以工人老师傅为主体,组成工人、领导干部、技术人员三结合小组,成功地制造了晶体管单阀冷液泵。工作原理:当绕在缸体外的线圈通电时,产生一个磁场,吸引缸内圆桶状的金属活塞向上运动,由于活塞中的阀珠被阀簧顶在阀座上,阀门关闭,所以进液管内的空气数量没有增加,体积却突然增大,相应压强减少,在外界大气压的作用下,冷却液通过进液滤网升入进液管。停止对线圈通电,磁场消失,在释放弹簧作用下,活塞向下运动,这时进液管面上的
Machine metal cutting, the tool and metal parts will produce high temperature redness, which requires the use of cold liquid to cool. At present, the majority of motor driven, centrifugal pumps or gear pumps for liquid cooling. I plant under the leadership of party committees at all levels, the workers master as the main body, composed of workers, leading cadres and technicians combined with the three groups, successfully manufactured a single valve transistor coolant pump. Working principle: When the coil around the cylinder is energized, a magnetic field is generated to attract the cylinder-shaped metal piston to move upwards. Since the valve ball in the piston is pushed on the valve seat by the valve spring and the valve is closed, No increase in the amount of air within the liquid pipe, the volume suddenly increased, the corresponding pressure to reduce the role of atmospheric pressure in the outside, the cooling liquid into the liquid through the filter into the liquid pipe. Stop energizing the coil, the magnetic field disappears, under the action of the release spring, the piston moves downward, then the liquid inlet tube surface
