我队广大职工，经过无产阶级文化大革命和批林批孔运动，提高了阶级斗争、路线斗争觉悟，激发了大干社会主义的积极性。在原齿筒式退心器的基础上，自行设计、试制了一台柱塞式水压退心器。通过实践，退心效果良好，解决了从岩心管内退岩心的困难，并减轻了劳动强度，提高了效率，现全队已推广使用。一、结构及作用原理主要由杠杆、柱塞，柱塞体，进排水阀等构成。作用原理及结构见示意图。根据杠杆原理可得：
Through the great proletarian cultural revolution and the campaign to criticize the proletariat and the proletariat, the vast majority of our team of workers and staff raised the awareness of class struggle and route struggle and aroused the enthusiasm of a lot of socialism. On the basis of the original gear-type ejector, a plunger-type hydraulic ejector was designed and manufactured by ourselves. Through practice, the effect of withdrawing the heart is good, solving the difficulties of darting the core from the core pipe, reducing the labor intensity and improving the efficiency, and the team has now promoted the use. First, the structure and role of the principle Lever, plunger, plunger body, into the drain valve and other components. Schematic diagram of the principle of operation and structure. According to the principle of leverage available:
