Type requirements: land type, indoor fixed installation. The mute unit adopts an integrated structure, and necessary shock absorbers (expansion damper joint and frame shock absorber) are added at the bottom and base of diesel engine and generator. The cooling fan of water tank blade and battery charger are equipped with protective cover to prevent hard objects from getting involved and damaging. Cooling mode: the cooling system of the unit can keep normal operation at ambient temperature, with fan cooling water tank and copper water tank for closed circulating cooling. Fuel oil specification: this unit uses 0 × 10 light diesel oil as fuel oil; is there a muffler for nail gun? There is a basic oil tank made of high-quality steel plate, and the thickness is not less than 4 mm. A buried oil tank is set as the standby oil tank of 2 * 600 kW generator set; the reserve oil tank is made of high-quality steel plate, and the thickness is not less than 4 mm. When the oil level of the oil tank is lower than the set value, the oil pump will supply oil automatically, and the oil supply will not alarm. When the oil level is higher than the set value, stop pumping and return to the oil tank through the overflow pipe. The fuel tank has exhaust pipe, etc. In order to meet the fire requirements. Oil way system: the bidder shall complete the oil circuit system between the standby oil tank, special muffler daily oil tank of steam gun and diesel generator set, and provide oil pump control box to realize the automatic start and stop of oil pump. Lubricating oil: the lubricating oil specification of the unit is 15w-40cf. Any change shall be explained in the bidding document. Diesel engine filtering system: dry cylinder air filter, shell diesel filter and oil filter are adopted, all filters can be replaced. Exhaust system: industrial heavy-duty exhaust muffler is adopted. The exhaust gas needs to be discharged outside the machine room after passing through the flue gas purifier to meet the corresponding emission standards. The smoke exhaust pipe is a finished smoke pipe, which should be made of stainless steel. The parameters of the stainless steel smoke exhaust pipe are: SUS304, stainless steel, 2.0 mm inside, 0.8 mm outside, and 50 mm heat preservation (aluminum silicate cotton), which must meet the requirements of smoke exhaust of generator set. The installation mode of smoke exhaust pipe and the installation position of flue gas purifier shall be determined by the bidder through site investigation. The flue gas purifier is made of high quality stainless steel. The bidder shall survey the site by himself to determine the quantity. The project is given in the form of itemized quotation, and the final settlement price will not be adjusted.
