QSK23-G3

Description

The QSK23 is an in-line 6 cylinder engine with a 23 litre displacement. This Quantum series utilizes sophisticated electronics and premium engineering to provide outstanding performance levels, reliability and versatility for Standby, Prime and Continuous Power applications.

This engine has been built to comply with CE certification.

This engine has been designed in facilities certified to ISO9001 and manufactured in facilities certified to ISO9001 or ISO9002.

Features

The QSK23 uses the Cummins High Pressure Injection (HPI) PT full authority electronic fuel system. The HPI PT fuel system is managed by a G-Drive Governor Control System (GCS) controller, which is provided for off-engine mounting in the genset control panel. The Quantum Control has a specific fuel system board to interface with the HPI-PT fuel system and provides an Engine Protection package giving greater customer flexibility and cost effective alternatives in the control design and the benefits of Full Authority electronic control CTT (Cummins Turbo Technologies) HX82 turbo-charging utilizes exhaust energy with greater efficiency for improved emissions and fuel consumption. Charge Air Cooling - QSK23 engine requires the use of an Air-to-Air heat exchanger or Charge-Air-Cooler (CAC) to reduce intake manifold temperature and to meet the lower emissions requirements CoolPac Integrated Design - Products are supplied complete with cooling package and air cleaner kit for a complete power package. Each component has been specifically developed and rigorously tested for G-Drive products, ensuring high performance, durability and reliability. Service and Support - G-Drive products are backed by an uncompromising level of technical support and after sales service, delivered through a world class service network

These guidelines have been formulated to ensure proper application of generator drive engines in A.C. generator set in-stallations. STANDBY POWER RATING: Applicable for supplying emergency power for the duration of the utility power outage. No overload capability is available for this rating. Under no condition is an engine allowed to operate in parallel with the public utility at the Standby Power rating. This rating should be applied where reliable utility power is available. A Standby rated engine should be sized for a maximum of an 80% average load factor and 200 hours of operation per year. This includes less than 25 hours per year at the Standby Power rating. Standby ratings should never be applied except in true emergency power outages. Negotiated power outages contracted with a utility company are not considered an emer-gency. PRIME POWER RATING: Applicable for supplying electric power in lieu of commercially purchased power. Prime Power applications must be in the form of one of the following two categories:UNLIMITED TIME RUNNING PRIME POW-ER: Prime Power is available for an unlimited number of hours per year in a variable load application. Variable load should not exceed a 70% average of the Prime Power rating during any operating period of 250 hours. The total operating time at 100% Prime Power shall not exceed 500 hours per year. A 10% overload capability is available for a period of 1 hour within a 12-hour period of operation. Total operating time at the 10% overload power shall not exceed 25 hours per year.LIMITED TIME RUNNING PRIME POWER: Limited Time Prime Power is available for a limited number of hours in a non-variable load application. It is intended for use in situations where power outages are contracted, such as in utility power curtailment. Engines may be operated in parallel to the public utility up to 750 hours per year at power levels never to ex-ceed the Prime Power rating. The customer should be aware, however, that the life of any engine will be reduced by this constant high load operation. Any operation exceeding 750 hours per year at the Prime Power rating should use the Con-tinuous Power rating.CONTINUOUS POWER RATING: Applicable for supplying utility power at a constant 100% load for an unlimited number of hours per year. No overload capability is available for this rating.

Data shown above represent gross engine performance capabilities obtained and corrected in accordance with ISO-3046 conditions of 100 kPa (29.53 in Hg) barometric pressure [110 m (361 ft) altitude], 25 °C (77 °F) air inlet temper-ature, and relative humidity of 30% with No. 2 diesel or a fuel corresponding to ASTM D2. Derates shown are based on 15 in H20 air intake restriction and 2 in Hg exhaust back pressure.

The fuel consumption data is based on No. 2 diesel fuel weight at 0.85 kg/litre (7.1 lbs/U.S. gal).

HCI634GSPECIFICATIONS & OPTIONS

STANDARDS

Newage Stamford industrial generators meet therequirements of BS EN 60034 and the relevantsection of other international standards such asBS5000, VDE 0530, NEMA MG1-32, IEC34, CSAC22.2-100, AS1359.Other standards and certifications can be consideredon request.

VOLTAGE REGULATORS

MX321 AVR - STANDARD

This sophisticated Automatic Voltage Regulator(AVR) is incorporated into the Stamford PermanentMagnet Generator (PMG) system and is fitted asstandard to generators of this type.The PMG provides power via the AVR to the mainexciter, giving a source of constant excitation powerindependent of generator output. The main exciteroutput is then fed to the main rotor, through a fullwave bridge, protected by a surge suppressor. TheAVR has in-built protection against sustained over-excitation, caused by internal or external faults. Thisde-excites the machine after a minimum of 5seconds.Over voltage protection is built-in and short circuitcurrent level adjustments is an optional facility.

WINDINGS & ELECTRICAL PERFORMANCE

All generator stators are wound to 2/3 pitch. Thiseliminates triplen (3rd, 9th, 15th …) harmonics on thevoltage waveform and is found to be the optimumdesign for trouble-free supply of non-linear loads.The 2/3 pitch design avoids excessive neutralcurrents sometimes seen with higher windingpitches, when in parallel with the mains. A fullyconnected damper winding reduces oscillationsduring paralleling. This winding, with the 2/3 pitchand carefully selected pole and tooth designs,ensures very low waveform distortion.

TERMINALS & TERMINAL BOX

Standard generators feature a main stator with 6ends brought out to the terminals, which are mountedon the frame at the non-drive end of the generator.A sheet steel terminal box contains the AVR andprovides ample space for the customers' wiring andgland arrangements. It has removable panels foreasy access.

SHAFT & KEYS

All generator rotors are dynamically balanced tobetter than BS6861:Part 1 Grade 2.5 for minimumvibration in operation. Two bearing generators arebalanced with a half key.

INSULATION/IMPREGNATION

The insulation system is class 'H'.All wound components are impregnated withmaterials and processes designed specifically toprovide the high build required for static windingsand the high mechanical strength required forrotating components.

QUALITY ASSURANCE

Generators are manufactured using productionprocedures having a quality assurance level to BSEN ISO 9001.

The stated voltage regulation may not be maintainedin the presence of certain radio transmitted signals.Any change in performance will fall within the limits ofCriteria 'B' of EN 61000-6-2:2001. At no time will thesteady-state voltage regulation exceed 2%.

NB Continuous development of our products entitlesus to change specification details without notice,therefore they must not be regarded as binding.
