自旋转柱塞抽油泵可以使柱塞在每冲程中随机转一下，不停地转变柱塞与泵筒的接触面，使柱塞圆周逐渐匀称磨耗的同时将砂粒或结垢从柱塞与泵筒之间排出，解决了磨蚀材料聚集所导致的紧张定位磨耗及杆柱脱扣。

This cone of concentricity and face runout vertical degree and CNC machine tools with a common location in a process out of the valve stem is easier to FILTER SERIES ensure design accuracy, while reducing the processing cost.

这样锥面的同轴度和端面的垂直度和跳动度用普通数控机床可以在一次定位中加工出来，阀杆的设计精度就比较容易保证，同时降低了加工成本。

It features big needle stitch, thick sewing material, high rotating speed, pressure-foot revival dual feed, bisynchronous feed for up feed, needle stem thread picking, bend needle drawing, eccentric positioning of principal axis, mechanical full-automatic lubrication to increase speed, ensuring the quality and prolonging the lifetime, making the material neat and regular with good-looking thread stitch and even needle pitch.

其特点：针距大，缝料厚，转数高，采用单压脚上下复活式双送料，双同步，上送料为双牙齿送料，针杆挑线，弯针勾线，主轴偏心定位，机械式全自动供油全润滑，提高速度，保证整机质量，延长使用寿命，使制品整齐，针距均匀，线迹美观牢固。

It can implement different path construction and deviation correction of the mole through applying a steering torque to the mole to change its working configuration and the orientation of the steering head slant face and make the mole advance according to the predetermined path. In this paper, Fussy Control is selected as the method of controlling the construction path of the mole and a set of detailed control strategy is established.

此外，针对气动冲击式轨迹可控穿孔机的施工特点，还专门设计了微型化和抗冲击的定位测量系统，以实现在施工过程中对穿孔机的监测，其测得的穿孔机实际运行轨迹用于和设计轨迹进行比较，作为对穿孔机施工轨迹进行控制的依据；以及由控向机构和挠性杆组成的控向系统，其作用是通过施加控向扭矩于穿孔机来改变穿孔机的工作模式及导向穿孔头斜面的朝向，从而实现不同性质轨迹施工和偏离修正，保证穿孔机尽可能按照设计轨迹进行施工。

What's more, a special locating and measuring equipment is designed according to the characteristics of the pneumatic percussive steerable mole, which is minisized and able to stand strong impact. By using it, the mole can be monitored during construction. By comparing the actual path to the predetermined path, the construction path of the mole can be controlled. The steering equipment comprises a steering tool and flexible pipes. It can implement different path construction and deviation correction of the mole through applying a steering torque to the mole to change its working configuration and the orientation of the steering head slant face and make the mole advance according to the predetermined path.

The round trip is driven by servomotor, matched up with precision ball screw and wire slide rail, to smooth the round trip of the blade and position accuracy.

切刀与主轴采用无级变速AC马达。5。行程以伺服马达驱动，配合精密滚珠螺杆及线滑轨，切刀行程顺畅，定位精确。

Therefore, you must release the take the wheel and loosen its teeth in its teeth on the shaft by time cam control rocker, but equipped page machine in its wheel is compact, inconvenient demolition, and pick out the teeth and inspection of pressure on the relative position of the key is to detect many parts of the machinery in a manner worthy, opening the restore time, the earliest possible time to 2300 hours, easily affecting production.

因此必须松开叼纸轮的定位，并且松开叼牙轴上受叼牙时间凸轮控制的摆杆，但由于配页机的叼纸轮安装较紧凑，不方便拆卸，且叼牙与检测压力相对位置是检测多帖关键的机械部位，拆开后，还原时间长，最快也要二三个小时，容易影响生产。

This three-wheeler is a sight with its long pole holding nine cameras, a GPS, a computer and a generator.

这辆三轮车本身就是一道风景——车上装有一根绑着有9部照相机的长杆、一个全球定位系统仪、一台电脑和一台发电机。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
