API RP 7C-11F:2008 pdf download.Recommended Practice for Installation, Maintenance, and Operation of Internal-Combustion Engines.
2.9 COOUNG AIR
Engines should be oriend to take advantage of prevailing winds. Suction or blower fans should be used as best suited to conditions. When engines are installed inside buildings, sufficient openings should be provided for the intake and exhaust of cooling air. Any danger of rirculating the cooling air should be eliminated by the use of ducts. Where therinally actuated cooling-water control valves are used, the capillaiy tubing should be as strt as prtica1 in order to prevent interference from outside temperature sources.
2.10 FUEL SYSTEM
When installing fuel piping. all foreign material should be remOVed from lines befurc they e connected to the engine. Unes of adequate size should be installed and adherence to safety codes should be observed. Adequate strainers and liquid taps should be provided in the fuel system. It is desirable to include a sation of flexible tubing for vibration isolation. Non-restricting shut-off valves should be provided in the fuel lines immedialy adjcnt to the engine. Gas regulators and their orifices and springs should comply with the engine builder’s recommendations.
2.11 BA1TERY STARTiNG SYSTEMS
The bnttery should be installed in a clean, cool, ce3sibIe, and vibration-free location, which is as close to the starting motor as practicable. Before installation, the battery should be checked for correct polarity.
2.12 GAS STARTERS
Where gas starters are used, exhaust gas should be piped a safe distance from the engine.
2.13 CONTROL EQUIPMENT AND SAFETY
DEVICES
Consideration should be given to the use of engine ternperature-control equipment and to the use of safety devicea such as low oil-pressure and high-temperature cutoffs. Such devices should be operable and nut blocked out.
2.14 LOADiNG OR UNLOADI40
Engines can suffer twisted frames or other barm from careless handling. During loading and unloading operations.
2.15 FiRES ANDR EXPLOSIONS
Consideration should be given to minimize potential fires and/or explosions. Sec Appendix A for recommendations.
3 DrillIng or Other Large internal- Combustion Engines
3.1 ENGINE-FLYWHEEL ALIGNMENT
When open-type air clutches are used, the alignment of the engine flywheel with the clutch is very important since misalignment can result in severe damage to the engine.
3.2 DIESELENGINE FUEL-PUMP LINES
In or&r to eliminate the possibility of air locking the fuel pump. diesel-engine fuel-pump overflow and leakage tines should be returned to the fuel tank and not piped directly tk into the pump suction. The return a must be properly baffled and vented to permit escape of vapor and air. Also, the rettun sbould be directed against a baffle or in a mani which avoids continuous agitation oldie fuel in the tank. In. jector return fuel may require cooling prior to return to fuel tank.
3.3 ELEVATiON OF DIESEL FUEL TANK
The elevation of the diesel fuel tank should be in accordance with the recommendations oldie engine manufactwer.
4 Multiple-CylInder Pumping Engines
4.1 WET STACKING
Unburned diesel fuel may accumulate in the exhaust systern if the load on the engine is reduced below a mitiirnum design poini This condition known as wet siacking should be considered when sizing a diesel-engine in accordance with recommendations from the engine nianufacturez
4.2 DESIGN OF V-BELT DRIVE
Care should be exeicised to design die V-belt dñve for the probable engine speed range.
4.3 INSPECTiON PRIOR TO STARTiNG
New pumping engine installations should be inspected by a competent mechanic prior to starting.
