2、泵常见故障判断及排除方法the failure and solution of spray pump,离心泵的工作原理operating principle of centrifugal pump,叶轮与泵轴固装在一起，当动力机通过联轴器和泵轴带动叶轮旋转时，叶片就带动叶片间流道中的液体作圆周运动，在离心力的作用下，液体以较大的速度和较高的压力，沿着叶片形成的流道，自重心想外缘运动，并通过蜗壳和扩散管流向排出管。由于液体不断排出，在泵壳内叶轮中心和吸入管内形成真空，吸入池中的液体在大气压或液罐内压力的作用下，源源不断地流进吸入管和叶轮。 The impeller and pump shaft

3、are fixed together. When the prime power machine drives the impeller to run through coupling and pump shaft, the leaf drives the liquid in the flow channel to do circular motion. With the effect of centrifugal force, the liquid forms a flow channel along the leaf to move from the barycenter to the r

4、im with high speed and pressure. Then it flows to discharge (port) pipe through volute casing and diffusion bell. Because of discharge of liquid, the vacuum zone at impeller center and suction line (port) of pump shell shall present. With the effect of atmosphere pressure and pressure of the fluid i

5、n tank (pit), the liquid in suction pit (tank) shall continuously go into the suction pipe and impeller.,离心泵的分类classification of centrifugal pump,按泵轴布置方式分：卧式泵 立式泵 Classification according to the layout of pump shaft: horizontal pump vertical pump 按泵吸入方式分：单吸泵 双吸泵 Classification according to the sucti

8、 pump,喷淋泵和灌注泵同为单级单吸离心式砂泵，在结构上具有许多相同点，均采用轴向吸入结构，过流部件为抗磨铸铁，适用于输送腐蚀性带有悬浮颗粒的钻井液或其它类似工况的液体介质，其参数设计充分考虑了所配套的设备能在最佳工况下工作，主要特点是零件的通用性和互换性强，轴封泄漏少，工作可靠，使用寿命长，维护方便。 但由于上述两种砂泵的使用场合不同，在外形结构尺寸、重量、功率等方面也存在着许多不同之处。The spray pump and charge pump is single stage and single suction centrifugal sand pump. They are simi

9、lar on structure. They both adopt axial suction frame; their liquid transfer components are made of antiwear cast iron and available to transfer caustic drilling liquid with suspending particles or some other similar liquid medium. The design considers fully the optimum working condition of mating e

10、quipment. The main feature is that the universal and interchangeability is strong, and the leakage of shaft seal is less, and work reliable with long service life and convenient to maintenance. But the two kinds of sand pump mention before are used in different condition, so the overall dimensions,

11、weight, power etc are different.,喷淋泵的作用function of spray pump,本公司钻井泵所配置的喷淋泵型号均为32SB180J-2.2kW（32PL），采用电机直联驱动和皮带轮传动两种方式，正反转均能使用。喷淋泵总成由喷淋泵、水箱、喷管等组成。其作用是在泵的运转过程中，由小齿轮轴通过皮带轮带动（或用电动机单独驱动），用水作为冷却润滑液，对缸套、活塞进行冲洗、润滑与冷却，以提高缸套活塞的使用寿命。 必须注意的是：在所有工作时间内，冷却液要充分供应到缸套及活塞上，不然冷却液的中断会立即导致活塞橡胶件及缸套的损坏。All the model of sp

12、ray pump mated with the drilling pump made by our company is 32SB180J-2.2kW（32PL）. All are driven by motor directly or belt transmission. It can run normally clockwise or counterclockwise. The spray pump assembly is consisted with spray pump, water tank, jet tube, etc. The function of it is that dur

13、ing the running process of mud pump, it is driven by belt or motor; the water is used as coolant and lubricant to wash, lubricate and cool the cylinder liner and piston to enhance the service life of cylinder liner and piston. Notice: during the work time, the cooling liquid should be supplied to th

14、e cylinder and piston enough. Otherwise, the piston rubber and cylinder liner shall be damaged rapidly.,灌注泵的作用function of charge pump,灌注泵的作用是在钻井泵运转过程中出现吸入压头不足时，为其持续不断的输送泥浆，以保证泵的正常吸入性能减少水击现象，延长零部件的使用寿命。 实践证明，即使钻井泵工作在有利于自然吸入的工况下，如果改用灌注泵吸入，可使泵的噪声振动有所下降，其工作性能稳定。The function of charge pump is that during

15、 the running process of drilling pump, when the suction pressure is not enough, it supply mud continuously to drilling pump (suction port) and reduce water hammer; to ensure the suction performance of pump and extend the service life of components. The practice proven that even though the drilling p

16、ump can work normally under natural suction, but if charge it with charge pump, the noise and vibration shall reduce greatly, hence the performance is improved.,灌注泵可直接安装在泵大底座上，也可单独安装。为满足用户的不同要求，灌注泵有正反转之分，其余所有外形及安装尺寸都是相同的，正转泵在左侧，反转泵在右侧（从吸入端看）。 2500SB8x6 砂泵推荐用于3200m以上钻机配套使用，2500SB 6x5砂泵推荐用于2500m以下钻机配套

17、使用，目前HHF-1600钻井泵选择配套的灌注泵型号为2500SB 8x6-13砂泵。 The charge pump can be installed on the skid of pump, or be installed separately. To satisfy the requirement of customer, the charge pump can classify to be positive running type and reverse running type. All figure and installation dimensions shall be the

18、 same. The positive running pump is at the left and the reverse one at the right (judge from the suction end). The 2500SB86 sand pump is commended to match with the drilling pump used for drilling rig of over 3200m, and the 2500SB 65 sand pump for rig of under 2500m. By now, the 2500SB 86-13 sand pu

19、mp is used as charge pump matched with HHF-1600 drilling pump.,喷淋泵及灌注泵的使用operation of spray pump and charge pump,由于灌注泵的结构、安装于维修维护与喷淋泵基本相同，在这里仅以喷淋泵为例进行介绍。 Because the structure, installation and maintenance of charge pump are similar to the spray pump, here we take the spray pump as example to introd

20、uce. 喷淋泵的安装installation 喷淋泵管路安装installation of pipelines 喷淋泵的使用operation,喷淋泵的安装installation of spray pump,泵安装：泵的安装位置应尽可能靠近抽送源，以缩短吸入段的长度，减少吸入损失。泵安装基础应水平、牢固可靠，以避免振动。 联轴器安装（为电机直联驱动）：泵和电机的较长使用寿命取决于弹性联轴器的较好对正。 皮带轮的安装： 两皮带轮轴线须平行，且端面误差不得超过2mm；皮带必须找正、松紧合适；电机安装须平稳、牢固。 Installation: The installation position

21、should try to be close to the suction source as possible to reduce the length of suction line and also reduce the suction loss. The base of pump should be level, firm and reliable to avoid vibration. The installation of coupling (driven by motor): the service life of pump and motor depends greatly o

22、n the alignment of the elastic coupling. Installation of pulley: the two shaft of pulley should be parallel and the error of end face should not be more 2mm. the extension of V-belt should be suitable and the installation of motor should be stable and fixed.,喷淋泵管路安装installation of spray pump pipelin

23、e,A.吸入管路截面积必须大于或等于泵流道断面积。 The section area of suction line should be bigger or equal to the section area of pump passage. B.吸入管路中不允许安装节流阀，但可以安装常开阀以减少液流紊乱，该阀只能在拆泵进行检修时才能关闭。 There shall not be choke valve installed in the suction line. But it can install a normally opened valve to reduce the flow turb

24、ulence. This valve just can be closed when disassemble the pump for servicing. C.为避免吸入管路中产生汽泡，抽送源和泵之间应从高到低逐渐渡。 To avoid air bubble in the suction line, the suction source and the pump should transmit gradually from the high place to the low place. D泵入口处的管路必须平直，其长度至少为吸入管路直径的二倍。 The line of the pump e

25、ntrance should be flat and straight, and the length is twice of the suction lines diameter at least. E当临时使用软管作吸入管路时，必须保证软管不被压缩，这是因为吸入段管内压力一般都比大气压低，在大气压作用下，软管被压缩，从而导致流量降低甚至断流。 When use hose as suction pipe temporarily, make sure the hose should not be compressed. Because the internal pressure of suct

26、ion pipe is often lower than the atmosphere pressure, with the effect of atmosphere pressure, the hose may be compressed to result the fluid flow be reduced and blocked. F为便于泵的检修，出口管路中应该安装常开阀。 There should be a normally opened valve installed in the discharge pipelines for convenience of pump servic

27、ing. G所有管路（包括入口管路）必须有自己的支撑，绝不允许由泵承受管路重量。 All pipelines (including the entry pipelines) should have its own support. It is forbidden to make the pump to bear the weight of pipelines. H当工作条件不明或不稳定时，出口管路中必须安装节流阀，以保证泵在设计点运行。 When the working condition is unclear or unstable, there should be a choke valv

28、e installed in the discharge pipelines to make sure that the pump runs under the design condition,喷淋泵的使用operation of spray pump,准备：A.用手转动泵轴，必须保证运转灵活，各处不得有摩擦声。B.给泵体和入口段管路注满引水，以排出空气。C.该泵空转不能超过5秒,必须注满液体方可运转,否则会造成机封损坏。 Preparation: A. rotate the pump shaft by hand, ensure that it can rotate freely witho

29、ut grating. B. charge the pump body and entry pipeline with water to discharge the air. C. the idling should not exceed 5 seconds It should run with liquid, or the mechanical seal may be damaged. 起动和运转: A.当运转前的准备做好后,启动原动机,逐渐开启闸阀至需要量。B.运转过程中,如发现噪音或其它异常现象应立即停机检查。 Start and running: A.
