Condensing water heater in the international arena began in the mid-1990s in China began in the beginning of this century, so far, five, six years of history in a short period of the development process, condensing gas water heater experiencethe two industry restructuring phase of ascension.
First condensing unit water heater in China since 2005, the rate of energy, and the advantages of brand has to start a technology research and development work with the product development of energy-saving condensing gas water heater, environmental indicators have reached or are close to the level of similar foreign products, the core technology is mature. 2007, the condensing water heater is now cutting edge in the market early.
In the last two years, the industrial technology research and development of domestic condensing gas water heater into the upgrade cycle of the main reasons are as follows:
Condensing gas water heater market, but the impact of high cost, the price is high. Some companies have reduced the technological content of products in order to reduce production costs, enhance the competitiveness of stage market to seize market share. But this has led to the decline of the overall technological level of the condensing gas water heater, resulting in the true meaning of the condenser marketing process is slow. Common practice in the international promotion of the condensation product is – the government out of special funds to subsidize energy-saving products, so that ordinary people can afford. For enterprises, the product sales reached a certain scale, the cost of the product can be naturally decline, and businesses will have more funds for technological innovation, and promote product development into the virtuous circle of development track.
Qiantang River Bridge in Jiashao tide tide-point, wide-shallow river, tidal rapids fast, bore a strong, large ships can not be in place, unable to use conventional steel box girder of large floating crane for installation. To this end, the project department through in-depth research and innovation, with a luffing crane type deck area of steel box girder cable-free installation, which is in bridge construction in the country’s third use, and the weight lifting maximum, the process of lifting crane bracket system and force the system requirements are quite high.
The first film to ensure smooth lifting of steel box girder, the project department has done a lot of preparatory work. Upon successful completion of load test basis, on January 12 board meeting held in the project brief meeting before lifting. Bridge headquarters, Hangzhou, Marine Department, Marine Department Shangyu, steel box girder manufacturing and transportation units, pilot units, supervision units and other interested parties were present at the meeting, the Qiantang River during the dry season combined with hydrological conditions at this stage, the maritime safety, mooring and lifting process a careful and detailed planning arrangements.
As Jiashao Bridge steel box girder bridge crane with using self-developed quick connect fittings. Quick Connector steel box girder section needs to be installed before lifting on to the steel box girder. To this end, 13 am, the project department rushed to arrange to carry salt Baita Mountain anchorage connectors were installed for lifting steel box girder bridge set aside enough time.
Currently, the project department of steel box girder brackets are being stepped up the slip area, to ensure completion before the Spring Festival four steel box girder installation plan.
Informed of the news of the accident, the Heilongjiang Provincial Secretary Ji Bingxuan do rescue work immediately made ??instructions to find out the specific circumstances of the underground, to speed up the pumping speed, as long as a glimmer of hope, we must make a hundred percent effort to save lives, to science and rescue, to avoid secondary disasters, good medical care to prepare, good family stability, with the news media reported the situation accurately.
Jixi City, Heilongjiang Province and relevant leaders immediately rushed to the scene directing rescue, long molecular Jixi Coal Company, Shen Long Dongsheng Coal Company chicken personnel, equipment, drainage rescue scene. State Administration of Work Safety dispatched to the scene of the rescue and accident investigators arrived on the scene was 13 evening, is assisting the local government organizations, rescue, do everything possible to rescue trapped workers, the situation fully investigate the accident.
Responsible for rescue work in the field of Jixi City Deputy Secretary-General, the Secretary for Work Safety, told reporters early east side, closing at 19:00 on the 13th, on-site rescue personnel reached 480 people, has been drained 2010 cubic meters, the water level elevation of 0.8 meters.
East side early introduction, the rescue of the materials required have been basically put in place, including 12 sets of pumps, vacuum switches 2, 6-inch iron pipe 1000 meters, 1000 meters of nylon tube and cable 1,400 meters. Drainage, the current drainage capacity has reached 160 m3 / h, the third times a drain line and pumps have been installed, you can start to solve power supply problems. The fourth trip is also about to complete the laying of drain line.
“Scene, the situation is more complicated, there are a lot of silt need to be cleaned, drained and rescue personnel are still great difficulties. Responsible for the accident identified, the need to exclude such water, the accident investigation experts to go down the investigation, at present, Jixi local inspection side and the police investigation. “Fang said the early East.
Car to drive away fear half the time out of state, especially for those beginners. Maintenance if they have some knowledge, some small problems do not need to resort to a auto repair factory. In addition, if a failure occurs in the course or No spare parts, how to do? Experts to teach emergency vehicle owner method.
When driving long distances in the wild, if the vehicle fuel tank leaking how to do? There is a good way: After chewing gum after the paste residue in the fuel tank will spill site, you can drop the fuel tank does not leak, because the gum tightly blocked drip dry after the site, not only an emergency, even do not replace the fuel tank. In addition, experienced air conditioning refrigerant leakage in the pipeline where chewing gum can also try to fill gaps. As long as not too serious leakage can generally be blocked leak.
Fan belts are generally used A-type belt, because it is relatively thin rubber, it is easy to wear, fracture. Therefore, the fan belt is driving will bring spares. But often leave spare fan belt in the car, not many people. Thus, in driving out long journey, if you find the belt has worn, you can use nylon stockings to tie the broken part of the belt is not easy on the belt from the pulley groove, not being broken, or even to maintain some distance. However, moving the throttle to ease some of the, otherwise, too much fuel, will be slippery nylon stockings, with a fixed belt drive.
As in the case of flat tire when driving, remember to stay calm, his hands to grip the steering wheel, the car slowly drove as far as possible the safety of the roadside stop. Replacement tires, the first diagonal form of the rim to loosen the screws. Then the jack on the chassis bracket, the body slowly rising, to ensure there is enough space, the spare tire into the normal inflation. And has been blasting out of the tires on the vehicle, the spare tire installed. Auto Fuel Line Fittings with tires, make sure the screws in the correct position to tighten the screws on the diagonal form. As the wheel is still hanging in the air, so the screws are not tight on to the state. When the tires touch the ground again after that they can form one by one with a diagonal locking the screw.
Inspection and maintenance of the fan drive system. Fan belts, bearings, motor and wheel wear or damage may result in loss of airflow or cooling performance.
Steam generation and infrared humidifier. Humidifier may be connected to the valve and hose leaks, drains may be clogged over time. Infrared humidifier bulb may burn out. These components should be checked regularly.
Condensate drains and pump inspection. Confirm and verify proper drainage pump function is blocked. Obviously, sewer blockages and overflows can cause sensor failure.
Check and clean reheat elements, investigation, and strengthen the supporting hardware.
Check compressor oil level and check for leaks. Compressor to run too much or too little oil will reduce the service life. Always use the same type of OEM-supplied fuel.
Evaporator coil should be checked regularly to make sure they are clean and free of debris. As you might imagine, dirty coil reduces the cooling efficiency.
Air cooled condenser coil should be checked regularly to make sure they are clean and free of debris. Motor should be tight, the bearings should be unfettered.
In order to reduce the associated failure, we recommend the maintenance of a comprehensive program of technical personnel and OEM training. When properly implemented, maintenance programs to ensure maximum reliability of the data center equipment, providing systematic inspection, to be effective for the initial fault detection and correction, regardless of fault or develop into major defects, may lead to costly downtime. Typical preventive maintenance, including inspection, testing, measurement, adjustment, replacement parts and housekeeping measures.
Pressure test, test, I ran more than 500 water purification plants, a complete suite of test equipment pressure test only Patio, beautiful, open can, very few stand several upgrades, most of the factory test pressure test device can only increase the static pressure, can not measure dynamic pressure and burst pressure pulse, and some have never even done a pressure test. Only now developing national standards for water purifiers for three pressure test requirements is estimated to improve the quality of water purifiers, especially leak-proof water will help, but is recommended as the standard, non-enforcement, small factories ignored, nor will be implemented.
On-site installation quality is also very important. For example, the cartridge filter built well, screw cap, can not be too loose, too loose will leak; can not be too tight, tight rubber band will cause distortion and leakage. Therefore, installers must be trained.
Connector loss is a common fault leakage, mainly due to the principle of joint is not perfect, and installation work is not in place. German-owned Water World Baokang (Nanjing) Co., Ltd. specializes in serious, repeated tests, the development of new water-tight, do not fall off the pipe fittings, has obtained national patents, about mass production, the water leak on the water purifier is definitely a blessing. Traditional fuel nylon quick connector and pawl, water seepage and off easily; Korea DMT quick connectors use seals and pawl, but such as the installation is not in place, or forget to install the locator card, the park is not enough water, ultrasonic welding is not strong and the front cover off so will result in leakage and flooding, the world’s joint Baokang improve these shortcomings, the water in the water park to increase plugs correction degree, two-way sealing ring seal through the side and face, the front cover with nuts to the locking pawl, greatly improving the reliability of joints, seepage rate, leakage rate is almost zero.
Jixi City, Heilongjiang Province and relevant leaders immediately rushed to the scene directing rescue, long molecular Jixi Coal Company, Shen Long Dongsheng Coal Company chicken personnel, equipment, drainage rescue scene.
State Administration of Work Safety dispatched to the scene of the rescue and accident investigators arrived on the scene was 13 evening, is assisting the local government organizations, rescue, do everything possible to rescue trapped workers, a comprehensive identification of accident-related circumstances. Responsible for rescue work in the field of Jixi City Deputy Secretary-General, the Secretary for Work Safety, told reporters early east side, closing at 19:00 on the 13th, on-site rescue personnel reached 480 people, has been drained 2010 cubic meters, the water level elevation of 0.8 meters. East side early introduction, the rescue of the materials required have been basically put in place, including 12 sets of pumps, vacuum switches 2, 6-inch iron pipe 1000 meters, 1000 meters of china nylon tube and cable 1,400 meters. Drainage, the current drainage capacity has reached 160 m3 / h, the third times a drain line and pumps have been installed, you can start to solve power supply problems. The fourth trip is also about to complete the laying of drain line.

In fact, in international markets mature, there is a similar Chinese 4S shops (OES)and the Auto Fuel Line Fittings Manufacturer market (IAM independent aftermarket) Two car maintenancemode. In the United States market, IAM about 70% or more; in the German market,about 60%. The share of passenger cars in China is much higher than the OES IAM.This is mainly for three reasons: First, Chinese consumers lack the expertise andparts recognition, trust services and parts of 4S stores; the other hand, vehicle manufacturers to strengthen the 4S shop ”factory is a good quality” image; third,China lacks the relevant regulations, constraints, China’s passenger carmanufacturers in the aftermarket has alleged monopoly measures. Parts pricing is far higher than its cost price, thus forming a ”4S too expensive” situation.
The Auto City in the IAM market is a group of auto dealers gathered at all levelsmade??. Compared to European and American markets, China’s auto partsdistribution is still in the early stage. Beijing alone, more than 10,000, and fierce competition. Or sale of counterfeits, or their OEM sales; Therefore, the sales price of the product relative to the 4S shop, the often surprisingly cheap, but quite a mixed bag, real to the enemy.
On-site installation quality is also very important. For example, the cartridge filter built well, screw cap, can not be too loose, too loose will leak; can not be too tight, tight rubber band will cause distortion and leakage. Therefore, installers must be trained.

Should be a last resort to remedy the situation, the water purifier water leakage sensor or component is installed on a volume of leaks, leaking components start to make water purifier inlet valve closed, cutting off water sources, or both alarms to prevent flooded the floor . Now there are many factory installed water purifier water leakage sensors and leak-proof water system.
The Division is located in Chaozhou, Guangdong into the polymer is a company specializing in nylon materials research, production and sales of high-tech enterprises, is China’s first manufacturer of MC nylon pipe, only the last ten years on the application of 23 inventions, utility models, exterior design patents. MC nylon developed to enhance their products back in 1993 was included in the national “Spark Program”, “Torch Program” and “Key New Product”, the product is widely used all over the country’s oil fields, petrochemical industry, salt industry, etc. high pH, high corrosion industry.
The summer of 2003, the Guangdong Branch into a national professional journal in Zhenjiang, Jiangsu Province found a company published “China Nylon Tube” advertising photos with their business exactly the same photo printed promotional materials. This is not only against the “Li Kui” reputation, but also a potential for user security threat. Guangdong Branch, respectively, into the Intellectual Property Office of Jiangsu Province and Jiangsu Province Administration for Industry presented the survey process the request, were rejected.
Administrative appeal of the road a dead end, into the Guangdong Branch decided to use legal means to enforce the patent rights. Happened in 2005, they found that the company will sell the allegedly infringing products into the Guangdong Branch of the old customers. Then in 2006, the Wuhan City Intermediate People’s Court, after several trials, Hubei Higher People’s Court on March 6, 2009 to make final judgments in civil, found the company infringed. But the company refused to accept the application for reconsideration brought to the Supreme Court, Supreme People’s Court on October 29, 2009 dismissed the application.
