查询词典 movable unit

The unit adopts variable displacement hydraulic pump, hydraulic cylinder, movable pulley and broad belt to transmit power,has the charecteristics of abundant recovery and full use of power,minor fluctuation of electric motor load, low height of the unit, long stroke length and convinence of adjusting the stroke length and pumping speed, can realize the performance of being fast on the upstroke and slow on the downs...

该液压抽油机采用变量液压泵—液压缸—动带轮及宽胶带传递动力，具有功率回收利用充分、电动机负载波动小、整机高度较低、冲程长、冲程和冲次调节方便等特点，可实现上快下慢的工作状态，并具有失载与过载保护功能，是一种结构简单、重量轻、能耗少、载荷大的新型长冲程液压抽油机。

Regarding the frequent occurrence of speed stalling of boiler axial flow primary fan in the operation of 600 mw unit in china,the cause of speed stalling was analyzed based on the actual measured data.the problem is mainly caused by primary air pipe resistance property variation,which caused the excessive opening of movable blades,the primary fan is working on the condition of higher wind pressure and lower flow.the approaches to reduce the speed stalling of primary fan and preventive measures are put forwa...

针对目前国内600 mw大容量机组锅炉轴流式一次风机运行中失速事故频繁发生的问题，在了解造成轴流式一次风机失速原理的基础上，根据实测数据对一次风机失速原因进行分析。主要原因为一次风管阻力特性的变化，使一次风机动叶开度过大，一次风机工作点处在高风压区低流量的工况点，是造成一次风机失速的主要原因，提出了运行中减少一次风机失速机率的处理方法及预防措施。

A new-type bike features that its pedal crank has an arc rack bar acting on the ratchet gear in single direction and in turn driving the drive chain wheel, a reset unit composed of crank mechanism is used to make left and right pedal cranks be pedaled alternatively, and its front movable saddle plate is connected via connecting rod to pedal crank for making rider comfortable. Its advantages are high drive performance and efficiency and saving labour.

一种新式自行车，其最大特点是蹬踏杆上含有一弧形齿条，由该弧形齿条上的轮齿作用于具有单向离合的棘齿轮，从而带动主动链轮转动，由曲柄机构组成的复位器使左右蹬踏杆能够交替连续踩踏以驱动自行车行驶，前活动座板与蹬踏杆由连杆相连结，从而实现同步摆动给以乘骑者踩踏感到舒适，该发明具有传动性能好，效率高，力损耗小等优点。
