1. Perkins diesel generator set maintenance of new units before the start of the cooling system to be filling the coolant. When filling, you should open the bleed valve upper engine cooling system, slowly cooling the coolant from the tank to the engine plus outlet added until no bubbles discharged from the bleed valves so far. Coolant should be filled to the cooling water tank below the outlet of the neck, not too full. After the filling is completed, the deflate valve is closed, and the water filter mounts sectional door open so DCA4 additives can be mixed into the cooling system. Cooling system used mainly by pure water coolant, antifreeze additives and DCA4 three components constitute liter coolant containing 50% pure water, DCA4 50% antifreeze additive and 0.5 units. With a good coolant can be used all year round and can be used continuously for two years. Because of pure water is purified, thus avoiding the formation of scale. Ethylene glycol or propylene glycol antifreeze means industrial use, can be reduced to improve the freezing point of water and the boiling point of water. The concentration of antifreeze should be 40%. 68%, the concentration is too high or too low will affect the ability of anti-freeze coolant. In most climates, antifreeze recommended concentration of 50%, freezing point of the coolant up -33cC. DCA4 additives in surface water systems form a protective film to prevent the liner and the body to produce cavitation and prevent sediment accumulation. Cummins generator charging generator battery charging generators Silicon Rectifier DC generators and alternators two kinds. Cummins generators currently the most widely used is silicon rectifier alternator. When T. Cummins generator for when the AC power silicon rectifier sweep l 6 只 silicon diode three-phase full-wave rectified 1000KW generator maintenance, and supporting the charge alternator regulator for use to charge the battery. Silicon Rectifier alternator main rotor, stator, and so on shell composed of silicon diodes. I. Physical appearance of a rotor shown in FIG. The rotor is the part that is not to produce a generator, which is mainly composed of an exciting coil, the magnetic pole and the collector rings and other components. Single pole shaped like a beak volts, a number of circumferentially spaced pole beak shape like claws f, so called claw pole. Every two claw-pole rotor intertwined since the corpse. General use of low-carbon steel claw pole punched together. Pressure mounted on the rotor shaft excitation coil, the coil is energized when the excitation of large generator repair, claw pole is called the pole. Turn - two side made of copper collector ring (or slip ring), insulated from each other and between them and the rotor shaft are insulated. On two collector rings connected with the excitation coil leads to both ends of a r respectively, two collector ring generator maintenance were in contact with the two brushes Brush rack so that the generator output is rectified After the introduction of the excitation coil current. 2. stator stator physical shape as shown. It consists of silicon steel sheets punched recess folded, embedded press star connection three-phase winding is connected 800KW generator maintenance in the recess, the trailing end of each phase winding together to form a neutral rli, and the other end member silicon diode board. 3. Front, front and rear cover, the rear end cover are cast aluminum alloy, the bearing housing is mounted at the two end caps steel jacket to increase its wear resistance. Bearing holes on air-bearing. Which is good generator maintenance | nave generator maintenance | on firewood provided by the Electrical and Mechanical and Electrical Equipment Co., Dongguan ShangXi firewood. Electrical Equipment Co., Ltd., Dongguan ShangXi Chai (www.dongguanfadianji.cn) strong, credible, diesel generator sets and other industries in Dongguan, Guangdong has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the diesel generator and you hand into the brilliant, for a better future!
