渣浆泵类型泵的简介

除了前面介绍的离心泵外,在石油天然气输送和处理厂还常用到其他类型的泵。在油田泵站和污水处理厂常用轴流泵,在输送黏度较高的润滑油和燃料油时,常用到往复泵、齿轮泵和螺杆泵等容积泵。在油库泵房中,常采用真空泵对离心泵灌泵以及抽吸油罐底油等。螺杆泵在油气混输以及原油输送中也得到应用。表2- 1给出了常用泵的主要特点及适用范围。

Brief introduction of slurry pump

In addition to the centrifugal pumps described above, other types of pumps are commonly used in oil and gas transportation and processing plants. Axial flow pumps are commonly used in oil field pumping stations and sewage treatment plants, and reciprocating pumps, gear pumps and screw pumps are commonly used when transporting lubricating oil and fuel oil with high viscosity. In pump room of oil depot, vacuum pump is often used to pump centrifugal pump and pump bottom oil of oil tank. Screw pump is also used in oil-gas mixed transportation and crude oil transportation. Table 2-1 gives the main features and application scope of common pumps.

Table 2-1 main features and application scope of common pumps

Oil pump type: screw pump

Advantages: self suction; simple structure, small volume; few faults, easy to use; stable work, uniform flow; large flow and head range; high efficiency; can transport viscous oil

Disadvantages: strict requirements on the transport medium, no solid particles impurities; not suitable for transportation of gasoline, kerosene

Scope of application: transportation of lubricating oil, fuel oil and diesel oil; high efficiency under high head and large flow

Oil pump type: reciprocating pump

Advantages: it can be self-priming; large allowable suction vacuum; high efficiency; it can transport viscous oil with little change in efficiency

Disadvantages: complex structure, large volume; uneven flow when working; unable to directly connect with the prime mover; many parts, many faults, difficult maintenance; not suitable for transporting gasoline and kerosene

Scope of application: transportation of lubricating oil, fuel oil and diesel oil; suction of oil tank bottom oil (small pump); suitable for conveying a small amount of liquid under high pressure

Oil pump type: gear pump

Advantages: self suction; simple structure, small volume; few faults, easy to use; can be directly connected with the prime mover; the flow is uniform; can transport viscous oil

Disadvantages: high requirements for parts processing, high price; small flow and head range; not suitable for transporting gasoline and kerosene

安徽快3开奖结果Scope of application: transportation of lubricating oil and fuel oil; suitable for occasions with small flow and head

Oil pump type: vortex pump

Advantages: self suction; simple structure, small volume, reliable operation; can transport liquid with gas content more than 5%; convenient installation and maintenance

Disadvantages: low efficiency, generally no more than 45%; can not use outlet throttle adjustment, can only use bypass regulation

Scope of application: especially suitable for low viscosity clean liquid with small flow and high pressure

安徽快3开奖结果Oil pump type: axial flow pump

Advantages: large flow rate, high efficiency, stable operation, liquid containing solid impurities, simple structure and convenient installation

Disadvantages: small head; small range of efficient operation area

Scope of application: especially suitable for medium with large flow, low head and low viscosity。 It is suitable for sewage treatment of combined station
