Providing, installation, testing and commissioning of 15 KVA DG set with allied works at Divisional office MICD Jammu

Providing, installation, testing and commissioning of 15KVA single phase silent type Diesel Generating Set of reputed make fitted inside canopy with allied works at Divisional office MICD Jammu. The detailed requirements include the following: 1. ENGINE: The diesel engine shall be four stroke cycle mutli-cylinder, water cooled, electric start, developing required BHP @ 1500RPM under NTP condition of BS:5514/ IS:4722 with latest amendments with an overload capacity of 110% for 1 hour in any specified 12 hours of continuous operation. The engine shall be started by a suitable starter motor engaging with the fly wheel ring gear and disengaging automatically when the engine starts. The equipment shall include an adequately rated OEM approved brand of batteries together with an automatic mains energized battery charger. The battery shall be capable of providing at least six starting cycles within a period of 5 minutes. The fuel injection system of each DG set shall be complete for the working of the DG set and inclusive of inline fuel injection pump, injectors, piping Insulated) & connections etc. Lubrication of the engine shall be by means of an engine driven integral pump. The pump shall have on the suction side a coarse strainer and on the delivery side a duplex ‘full flow’ fine filter complete with changeover cock incorporating pressure by-passes to facilitate oil flow to the engine, should the filter become blocked. The lubricating oil system capacity shall be sufficient to enable the engine to run continuously for 12 hours at any load without replenishment. The engine shall be fitted with required air filters with replaceable elements. The engine shall be completed with fuel and lube oil filters with replaceable elements. The governor shall be Mechanical/ electronic type and should be capable of fine governing of speed. The engine shall be efficiently silenced with suitable noise attenuators provided at cooling/combustion air inlets and outlets and exhaust silencers complete with interconnecting pipe and fittings. Supports for each complete system shall be of the anti-vibration type and due allowance for expansion of the exhaust system shall be made by the inclusion of expansion bellows. Exhaust pipe shall be lagged with a removable Aluminum cladding. The engine shall be provided with following devices for alarm and shutting down the engine automatically. Low lubricating oil pressure. Engine over-speed. High cooling temperature. Over cranking. Unbalanced load protection Audio alarm A sturdy elastic coupling shall connect the engine and the generator, and both shall be mounted on a common base plate forming part of the supply, proven and highly effective anti-vibrating mountings shall be provided between base plate and concrete foundation. 2. Sound Attenuated System: D.G. Set shall be conforming to MOEF/ CPCB II standards and noise level is to be 75 dB(A) at 1 m in open field environment as per ISO 8528 part 10. The system shall be made of high class sheet metal fabricated panels of suitable thickness having modular construction for ease of assembly and dismantling. Sound proofing is done with high Quality Fire proof acoustic material i.e Foam/ Mineral Wool /Rockwool (conforming to IS 8183). An additional axial flow fan may be provided to achieve optimum output to meet the air requirement and air changes and acoustic hoods with noise splitters 1f required, to block and reduce the sound leakage. Silencer shall be provided for maximum noise reduction and specially designed vibration isolators are used to restrict the transfer of vibrations from the DG set to the body panels and its surroundings. Emergency stop switch to be provided outside the container and tube rod should be provided for light inside the canopy. 3. ALTERNATOR: The alternator shall be of self-excited, self regulated, self ventilated in brushless design, provided with suitable automatic voltage regulator and shall conform to BS:2613/ IS 4722 and shall give rated output at NTP conditions. The voltage regulator shall maintain its setting for long periods without adjustment. Means shall be provided for a limited degree of manual adjustment of the output voltage setting. The alternator shall be directly coupled to and share a common high bedplate with the prime mover. The degree of protection for the generator and exciter shall be not less than IP -23. Cooling of the generator shall be by a radial-flow fan. Generator bearings shall be of the ball or roller type, rated for long life and pre-packed with sufficient grease for operating over long periods without replenishment. The stator and field windings shall consist of electrolytic copper conductors insulated throughout with Class H material. Voltage regulation should be maintained within +/- 1% from no load to full load including cold to hot variation at any power factor from 0.8 to unity. Neutral shall be solidly earthed. The D.G. Set should be fitted with manual standard control panel which shall have all latest features and safety controls of the D G Set for 15 KVA capacities as per OEM recommendations. 4. FUEL STORAGE: Unit shall have in built fuel tank of suitable capacity as per manufactures recommendations in the base rail and shall be installed in a position where any fuel leakage cannot impinge on exhaust pipe or other hot engine surfaces. The tank shall be provided with all necessary fittings. The tank of the D.G. Set shall be atleast half-filled for testing and commissioning of the D.G. Set. The charges on this account shall be borne by the firm and no extra cost whatsoever shall be entertained by the department. 5. EARTHING: The generating set and all associated equipment, control and switch gear panels must be chemically earthed before the set is put into operation. Earthing for DG sets shall be of metal conductors provided strictly as per OEM recommendations and as per BIS and Indian Electricity Act. The job also includes construction of platform of suitable size for proper resting of the DG set inside the shed and modification of existing entrance door to the required dimensions of the shed for safe movement of the DG Set through the entrance by way of cutting, welding and providing/fitting of the additional MS angle/GI Sheet required as per site conditions. And also complete painting of the newly fabricated entrance door and the protection grills on the two sides of the Shed. The job also includes the carriage of defunct 15 KVA DG set lying at Divisional office MICD Jammu to Divisional Store of MICD Jammu. The job further includes providing/fitting of Changeover switch of reputed make of suitable capacity, wires/cables from DG Set to Changeover Switch and earthing along with other safety devices and related works. The complete job includes cost of third party inspection of DG Set by CEIL/RITES/any other government approved agency, material, labour charges, crane charges, transportation/shifting charges up to the site of work including installation, testing and commissioning on full load inclusive of all taxes as applicable.
