In this paper ,to overcome the shortcomings in 3MK133 Groove Grinder's hybrid spindle system that the shallow slots of the throttler are easy to be blocked and difficult to be disassembled to clean,we use the throttler which is put on the big-side surface of the conical bearing to replace the traditional throttler, change gap throttling to capillary throttling, and adjust the taper of the conical bearing , oil return way , seals and sealed mode.

针对 3MK133沟道磨床动静压主轴系统中，节流器浅沟容易堵塞及拆卸清洗不便等缺陷，提出采用端置式节流器替代原有的内置式浅沟节流器，变间隙节流为毛细管节流，并相应调整了主轴系统中圆锥轴承的锥度、回油通路、密封装置及密封方式。

Media Help Everyday we are exposed to the steam often divided into two, one, the boiler steam - saturated steam 2, thermal power plants out of steam - superheated steam 1, a relatively stable temperature and pressure saturated steam, temperature lower than 250 ℃, working pressure lower than 1.6Mpa 2, superheated steam temperature and pressure changes of a high base temperature up to 400 ℃, working pressure is lower than 4.0Mpa For the first steam, we usually use soft sealing steam solenoid valve as follows: Structural characteristics This valve is a valve and Balance valves main valve by the two vice components with the second open valve Pilot solenoid valve Heat: electromagnetic part, some with special high temperature seals and sealing materials, electrical materials, and apply a variety of insulation measures Wear: selection and reasonable Globe Valves guidance suite valve cup and clever use of fluid lubrication, reduce wear, increase life expectancy Resistance to condensation: condensation of steam pipeline valve on the steam water is an important factor in action, the valve will not affect the condensation water Other uses - soft sealing steam solenoid valve This series solenoid valve can Safety valves be widely used in textile, printing, chemicals, plastics, rubber, pharmaceutical, food, building materials, machinery, electronics, surface treatment and research sectors and bathroom, dining room, air conditioning automatic control system.

介质说明日常生活中我们接触到的蒸汽常分为两种，1、锅炉蒸汽-饱和蒸汽 2、热电厂出来的蒸汽-过热蒸汽 1、饱和蒸汽温度压力相对稳定，电动阀门执行器温度低于250℃，工作压力低于1.6Mpa 2、过热蒸汽温度压力变化基数较大温度最高可达400℃以上，工作压力则低于4.0Mpa 对于第一种蒸汽，我们通常会选用氧气专用阀、铜阀门软密封的蒸汽电磁阀如下：结构特点本阀是由副阀和主阀两大部件构成的先导式二次开阀的电磁阀耐热：电磁部分、密封件部分用特种耐高温电工材料和密封材料，并应用了各种隔热措施耐磨：选材合理，电站阀门阀杯和导向套间巧妙地利用流体的润滑作用，减少磨损，提高寿命耐冷凝：蒸汽管道的冷凝水是影响蒸汽电磁阀动作的重要因素，本阀则不受冷凝水影响其他用途-软密封蒸汽电磁阀本系列电磁阀还可广泛地应用平衡阀纺织、印刷、化工、塑料、橡胶、制药、食品、建材、机械、电器、表面处理和科研部门以及浴室、食堂、空调等自控系统。
