Submersible pumps

Beam pumping and electric submersible pumps (ESP) require a source of power. On land it may be convenient to tap into the local electricity network, or in the case of the beam pump to use a diesel powered engine. Offshore (ESP only) provision for power generation must be made to drive down hole electric pumps. [Pg.259]

For greater depths or as an alternative to the wet-pit design, a submersible pump (Fig. 7b) having a special water-tight motor can be used. [Pg.293]

Significant improvements have occurred in the designs of these motors so that the submersible pump is a rehable option to a wet-pit pump. [Pg.293]

A more economical alternative is found in a submersible pump where the pump, directly coupled with the prime mover, is slid into the tubewell through narrow pipes. Narrow pipes are easy to sink into rocky terrain or very deep water levels. They are less expensive and are easy to install due to the elimination of the need for a pump house. Once the unit is slid into the well it requires little maintenance. (See Figures 7.5-7.7.) Such pumps have a standard centrifugal multistage arrangement, and the motors are required to work under water or any other liquid. These motors have an exclusive application for submersible pumps. [Pg.170]

The application and use of deep-well turbine and submersible pumps, is extensive and a choice will depend upon the depth of liquid and the rate of discharge. In rocky areas, where the digging of larger well cavity is a difficult task, submersible pumps provide an easy alternative. Similarly, for higher heads and where only a small quantity of liquid is to be pumped, these pumps are preferred. We discuss below the characteristics of these motors and the application of these pumps. [Pg.171]

You can only raise a column of cold water in a pipe a maximum of. S.S.9 ft with a pump in suction lift. Beyond 34 ft, the water will boil or vaporize. This is the reason why submersible pumps and vertical turbine pumps exist. I here is no limit to the distanee you can push a liquid from below, but you can only a.spirate a liquid a maximum of 34 ft from below the pump. [Pg.27]

The total investment cost for the aquifer system (wells, submersible pumps, tubing, control equipment, electrical cables, well chambers and heat ex- changers) was approx. 350,000 Euro. The specific investment cost is then roughly 370 Euro/kW. [Pg.237]

It is necessary to pump water at 70°F (Pv = 0.35 psia) from a well that is 150ft deep, at a flow rate of 25 gpm. You do not have a submersible pump, but you do have a centrifugal pump with the required capacity that cannot be submerged. If a 1 in. sch 40 pipe is used, and the NPSH of the pump is 15 ft,... [Pg.258]

Of course the only way to keep this 250W behemoth running for more than a minute without hitting the IC s internal OTP (over temperature protection) was to use a water-cooled heatsink, which my rather lab-ratty senior tech fashioned in less than half a day with some tubes, strips of metal, high-temp solder, and a sump (submersible pump). Note that the dissipation in the TO-220 was about 15W at this power level (calculated and measured). Yes, if you think that is a wee bit too much for a TO-220 to handle, I am on your side. [Pg.129]

The produced oil or gas is connected to surface flowlines from the wellhead pumping unit or surface regulating valve assembly typically referred to as a Christmas tree but to its arrangement. The flowlines collect the oil or gas to local tank batteries or central production facilities for primary oil, water, and gas separation. The reliability of electrical submersible pumps (ESPs) has increased to the point where the submersible electrical pump is commonly used for the production of liquid hydrocarbons where artificial lift is required for production. [Pg.11]

Where a significant lift is required such as offshore, several options are available such as a shaft driven, hydraulic drive or electrical submersible pump. Shaft driven vertical turbine pumps historically have been used extensively offshore, but recent reliability improvement with electrical submersible pumps and hydraulic drive units have been eagerly accepted as they eliminate alignment problems, topsides weight and in some instances are less complex than the right angle engine driven vertical turbine units. Hydraulic calculations for offshore pump installations must remember to account for tide and wave fluctuations. [Pg.207]

A recent innovation to improve recovery functions is a variable-speed submersible pump. When used with electronic controls, it is possible to select a fluid surface elevation and adjust the pumping rate periodically to maintain that fluid level at that elevation. Another adaptation of existing control technology uses an electrically adjustable valve to throttle the pump output. As the fluid level declines, the throttle restricts flow to prevent a further decline. [Pg.227]

The second option considered was use of interception wells. One- or two-pump wells could be constructed at calculated spacings to create a hydraulic trough parallel to the canal to intercept the product. This design was considered more acceptable to the safety officer and the facility engineer, but was rejected by the maintenance foreperson because of the relative complexity of the operation system. The number of submersible pumps and sophisticated electronic controls would have required employment (or training) of technical specialists beyond the cost budgeted under normal operations. [Pg.367]
