Test tasks: to check whether the loose connector; hand plate coupling the rotor to move a few laps to see whether rotation and flexible unit, whether there is uneven sound and light and heavy feeling, to determine whether pump or foreign body axis is curved seals, such as the installation is correct; inspection seal on the 20th cavity clean lubricants are added 1 / 2 cavity space; pump unit surface is clean; unit no-load test shift.

试车工作：检查连接件是否松动；用手盘动联轴器使转子转数圈，看机组转动是否灵活，是否有响声和轻重不匀的感觉，以判断泵内有否异物或轴是否弯曲，密封件安装正不正等；检查密封腔内的清洁20号润滑油是否加注1/2腔内空间；泵机组表面是否干净；机组转向空载测试。

BH400 pump can put on plunger or piston,Than conventional piston pump a wide range of work.

BH400泵可装活塞也可装柱塞，比常规活塞泵的工作范围广泛。

According to the conditions under the oil well and the technical requirements,the pump structure is changed from the plunger form to the piston form to compensate the wear in running of the piston ring by elasticity of itself.

活塞式抽油泵是目前普遍采用的采油设备，由于泵筒发生不同程度的磨损，导致在抽油过程中出现泄漏，根据油田井下的工况和技术要求，在不改变泵筒的前提下，把柱塞式结构改成活塞式结构，靠活塞环自身的弹性力来补偿工作运行中的磨损，所研制的活塞环，经油田的实际应用，收到良好的应用效果

Since the rotary plunger pump piston at each stroke can randomly rotate constantly change with the pump plunger cylinder contact surface, so that circular plunger gradually wear uniform or scaling at the same time, sand from the plunger and pump barrel between discharge and resolved accumulation Materials abrasion caused by wear and serious positioning rod release.

自旋转柱塞抽油泵可使柱塞在每一冲程中随机转动，不断地改变柱塞与泵筒的接触面，使柱塞圆周逐渐均匀磨损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引起的严重定位磨损及杆柱脱扣

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。

In consideration of thread fracture of 3515-type plunger pump head widely used in oilfield,the failure analysis is given.

针对在油田广泛应用的3515型柱塞泵液力端一体泵头体存在的螺纹断裂问题，进行失效分析，提出3种改进结构，有广泛的应用前景和市场效益。

Under normal circumstances, hydraulic components are not interchangeable with the couplings, but in practice some redeployment of the plunger pump repair is feasible.

通常情况下，液压元件的配合偶件是不能互换的，但在实际中有的中开泵泵重新调配柱塞进行修复是可行的。

Under normal circumstances,hydraulic components are not interchangeable with the couplings,but in practice some redeployment of the plunger pump repair is feasible.

通常情况下，液压元件的配合偶件是不克不及互换的，但在实际中有的中开泵泵重新调配柱塞进行修复是可行的。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
