8、注泵的结构特点 structure feature of spray pump and charge pump第6页,此课件共24页哦 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
9、stage and single suction centrifugal sand pump.They are similar 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
10、considers fully the optimum working condition of mating equipment.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 use
11、d in different condition,so the overall dimensions,weight,power etc are different.第7页,此课件共24页哦喷淋泵的作用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,
12、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 spray 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,w
13、ater tank,jet tube,etc.The function of it is that during 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 t
14、ime,the cooling liquid should be supplied to the cylinder and piston enough.Otherwise,the piston rubber and cylinder liner shall be damaged rapidly.第8页,此课件共24页哦灌注泵的作用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
15、有所下降,其工作性能稳定。The function of charge pump is that during 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.Th
16、e practice proven that even though the drilling pump 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.第9页,此课件共24页哦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)。2
