          加氣混凝土專用泵
          添加時間:2020.12.19

          加氣混凝土專用泵的優點

          (1)流量均勻。當螺桿旋轉時,密封腔連續向前推進,各瞬時排出量相同。因此,螺桿泵的流量比往復泵、齒輪泵要均勻。
              (2)受力情況良好。多數螺桿泵的主動螺桿不受徑向力,所有從動螺桿不受扭轉力矩的作用。因此,螺桿泵的使用壽命較長。有些泵做成雙吸結構,還可以平衡軸向力。
              (3)除單螺桿泵外,其他螺桿泵無往復運動,不受慣性力影響,故轉速可以較高,一般轉速為1500~ 3000r/ min。
              (4)運轉平穩.嗓聲小。被輸送液體不受攪拌作用。螺桿泵密封腔空間較大,有少量雜質顆粒也不妨礙工作。
              (5)有良好的自吸能力,因桿密封性好,可以排出氣體,動時可不用罐泵,可作氣混相輸送。由于密封性好,可在較壓力下工作,壓力可達300*10Pa。
          三、加氣混凝土專用泵的類型及其特點

          三種類型螺桿泵的比較見表2-2。
          四、加氣混凝土專用泵在油氣混輸中的應用
              在油氣田開發工程中.用于遠距離輸送未經處理的原油或部分處理的油氣水多相混合液體的氣液兩相流泵或油氣水多相流泵稱為多相泵,或稱為混輸泵。采用多相泵技術可以縮短油田生產周期,提高油田產量,節省油田投資,延長老油田壽命。
              目前國外已開發研制出多種類型的多相泵,按照使用場合不同,分為陸上多相泵和水下多相泵;按照工作原理的不同,又可分為旋轉動力式多相泵和容積式多相泵,前者包括螺旋軸流式多相泵、離心泵、對轉式濕式壓縮機等,后者包括單螺桿泵、雙螺桿泵、隔膜泵、線性活塞泵等。

          Advantages of special pump for aerated concrete

          (1) The flow rate is uniform. When the screw rotates, the seal chamber is pushed forward continuously, and the instantaneous discharge is the same. Therefore, the screw pump flow than reciprocating pump, gear pump to uniform.

          (2) The stress condition is good. The driving screw of most screw pumps is not affected by radial force, and all driven screws are not affected by torsion moment. Therefore, the service life of screw pump is longer. Some pumps made of double suction structure, can also balance the axial force.

          (3) In addition to single screw pump, other screw pumps have no reciprocating motion and are not affected by inertial force, so the speed can be higher, generally 1500 ~ 3000r / min.

          (4) Smooth operation and low voice. The transported liquid is not agitated. Screw pump seal cavity space is large, there is a small amount of impurity particles do not hinder the work.

          (5) It has good self-priming ability. Because of the good sealing performance of screw, it can discharge gas. It can be used for gas-liquid mixed phase transportation without tank pump when starting. Due to its good sealing performance, it can work under high pressure, and the pressure can reach 300 * 10Pa.

          3、 Characteristics of aerated concrete pump

          The comparison of the three types of screw pumps is shown in table 2-2.

          4、 Application of special pump for aerated concrete in oil and gas mixed transportation

          In the oil and gas field development project, the gas-liquid two-phase flow pump or oil-gas-water multiphase flow pump used for long-distance transportation of untreated crude oil or partially treated oil-gas-water multiphase mixed liquid is called multiphase pump or mixed transportation pump. The application of multiphase pump technology can shorten the production cycle of oilfield, improve the production of oilfield, save investment and prolong the life of old oilfield.

          At present, many kinds of multiphase pumps have been developed abroad, which can be divided into onshore multiphase pumps and underwater multiphase pumps; According to different working principles, it can be divided into rotary power multiphase pump and positive displacement multiphase pump. The former includes spiral axial flow multiphase pump, centrifugal pump, counter rotating wet compressor, etc., while the latter includes single screw pump, twin-screw pump, diaphragm pump, linear piston pump, etc.
