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. Coolant all year round with a good use of generators for rent, 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 generator rental price, 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. Diesel generators importance of service industries and services as an important industry in our country, has made rapid development in recent years, gradually increased the proportion of China's industrial structure, the importance of the increasingly prominent in promoting China's economic development played a big role. Services including transportation, storage and postal industry, wholesale and retail, residential services, accommodation and catering and other industries, these areas and people's lives, to ensure the normal operation of the economy. In our daily life and production, often will encounter power shortages, blackouts government trailer generator rental, but had to stop normal operations. Therefore, many companies are considering the issue since the purchase of diesel generator sets, and this is a particularly important issue. 1, some companies will take into account the purchasing power of the generator will increase operating costs; 2, in the peak period, and occasionally hear of a few power outages, it is not surprising thing, however, the shortage period, companies due to power failure interrupted normal business, will bring more costs, long-term accumulated import generator rental, the opportunity cost of the enterprise greatly increased economic efficiency of enterprises will be greatly reduced. Therefore, purchasing a generator as a backup power source, is imperative. For example, Mr. Zhang invited friends over to celebrate the birthday of a KTV, KTV power outage at the event, and all the activities of a termination of all time, is not to let Mr. Zhang felt sorry for friends? Many hotels, KTV establishments have adopted the heavy Kang generator diesel generator set production equipment. Silent generator rental, the diesel generator (certified), Nanshan generator rental is provided by diesel and Electrical Equipment Co., Dongguan ShangXi. Electrical Equipment Co., Ltd., Dongguan ShangXi Chai (www.dongguanfadianji.cn) is an industry leader in Dongguan, Guangdong, diesel generator sets, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. On the diesel generator leadership with the staff warmly welcome all inquiries negotiations to create a better future for diesel generators.
