【摘要】：本設(shè)計將目前已經(jīng)在石油采油等領(lǐng)域得到廣泛應(yīng)用的單螺桿式泵,應(yīng)用于增壓注水泵。擬發(fā)揮單螺桿泵的結(jié)構(gòu)簡單,流量均勻,壓力穩(wěn)定,易損件少,成本低等諸多優(yōu)點(diǎn),為滿足注水單井的高壓需求,提高油田注水系統(tǒng)效率,降低注水能耗及成本,做出新的嘗試。 設(shè)計采用兩個螺桿襯套副,對稱布置,以平衡單螺桿泵的較高的軸向力,通過該設(shè)計,可以免去止推軸承設(shè)計,而且,增大了泵的流量。 采用中間進(jìn)水,兩端出水方案,則兩端高壓,中間低壓,兩螺桿襯套副之間,需要安裝耐軸向壓力的萬向聯(lián)軸器。設(shè)計采用瓣式萬向聯(lián)軸器,其芯部的定位球,可承受軸向壓力載荷。 多頭單螺桿泵較單頭單螺桿泵,有著多方面優(yōu)勢,設(shè)計采用運(yùn)動比值為2/3的雙頭設(shè)計,采用短幅內(nèi)擺線的外等距曲線作為襯套的齒形曲線,其共軛曲線作為螺桿的齒形曲線,并對型線多個特征參量進(jìn)行了針對性分析和設(shè)計,在保證使用壽命的前提下,充分發(fā)揮螺桿襯套副的機(jī)械水力性能。 傳動軸端采用撓性軸連接和填料密封設(shè)計,并設(shè)計了配套的減速箱。
[Abstract]:In this design, the single screw pump, which has been widely used in oil production and other fields, is applied to the supercharged water injection pump. The single screw pump has many advantages, such as simple structure, uniform flow, stable pressure, less easily damaged parts, low cost and so on. In order to meet the high pressure demand of water injection single well, improve the efficiency of oilfield water injection system and reduce the energy consumption and cost of water injection, a new attempt is made. Two screw bushing pairs are used in the design to balance the higher axial force of the single screw pump. Through this design the thrust bearing design can be avoided and the flow rate of the pump is increased. If the intermediate inlet and outlet schemes are adopted, then the two ends of high pressure, middle low pressure and two screw bushing pairs need to be fitted with a universal coupling resistant to axial pressure. Can withstand axial pressure load. The multi-head single-screw pump has many advantages over the single-head single-screw pump. The design adopts the dual-head design with the motion ratio of 2/3, the outer equidistant curve of the short amplitude inner cycloid as the tooth profile curve of the bushing, and the conjugate curve as the tooth profile curve of the screw. Several characteristic parameters of the profile line are analyzed and designed to give full play to the mechanical and hydraulic performance of the screw bushing pair on the premise of guaranteeing the service life. The transmission shaft end is designed with flexible shaft connection and packing seal, and a matching deceleration box is designed.
