Welded joint

It is generated by the pipeline flow of the medium itself force automatically turned on and off, is an automatic valve. Check valve for pipeline system, its mainrole is to prevent the media back, to prevent the pumpand drive motor reversal, and the container medium discharge. A one-way valve is only for unidirectional flow control, not as safety relief device.

Q: How to choose a good use of solar energy: See brandAt present, there are more than 5 thousand brands of solar water heater industry, of which, a small family workshop type enterprises accounted for the majority of such enterprises weak competitiveness, the average life expectancy of enterprises, but only 1.5 years. Consumers choose products produced by such enterprises, often a few years later will become a three noes products, the interests of consumers can not be guaranteed. Therefore, consumers should choose in the country's high visibility of the big brands, big brands of solar water heaters not only reliable product quality, but also to provide consumers with long-term after-sales service protection.

Q: In the domestic high temperature solar energy collector can achieve how many degrees, the existing product and the technology form?: Solar thermal power can be divided into three categoriesTrough system, tower system and dish system, they all belong to medium and high temperature system,Trough system is relatively popular in the other two categories, but also the most promising class. Operating temperature of 400~700 degrees Celsius, the scale is not limited to a few dozen megawatts, up to the level of Gigabit, there are some examples of successful commercial operation abroad. There are many prototypes in China, but there is no practical system.

Q: Solar electric vehicle charging device: Electric vehicle using solar silicon and polysilicon combination surface for Ling lighting plate, high quality and high efficiency crystalline silicon plate, the weak light response is very good, high photoelectric conversion efficiency, both indoor and outdoor sunlight, can be 24 hours of uninterrupted charging for electric vehicles to absorb light, can meet the different electric vehicles with electric load.

Q: Is it hot in summer and the water is hot in winter?: Wall type solar water heater can belong to the separated type solar hot water system, water tank placed in the balcony or exterior wall, the collector is placed at the south facade of building a balcony wall hanging type solar water heater with flat collector to absorb solar radiation into heat, heat to reach the water tank and the water heat exchanger, so that the temperature of the whole the water tank is increased gradually, let the user can enjoy free hot water from the sun.The successful use of plate heat exchanger technology in wall mounted solar products, not only improves the thermal efficiency of balcony wall products, and the successful implementation of the building safety products and life integration, so that the water heater installation expanded to all floors and is not limited to the roof, and greatly lifted the traditional solar water heater, frozen fried tube, easy Water Leakage, easy scaling problems.

Q: Is there any water in the solar energy to water?: How much is the automatic water supply set level up to the number 2 can not need to fill 100 set automatic water temperature time to remove any fill

Q: Or must there be built - in battery? If yes, then use the mobile phone lithium battery can?: Solar panels because of light effects, such as shadow, the angle, so the output voltage is not stable, not stable in 5V, generally with a simultaneous mobile power output and input to the panel itself has a built-in battery, then of course better.

Q: Good solar polymer or monocrystalline: Spark solar energy products are also exported to many countries and regions such as Italy, Hongkong, Taiwan, the United States, Japan, Korea, Germany and other regions. After years of continuous development and improvement, not only to ensure good quality requirements, and won the domestic and foreign business partners to praise and affirmation. Stand on your point of view the factory must promise: fast delivery! Quality assurance! Price service is good. This season can undertake a large number of solar panels. This product can be customized for the price can also be agreed! Welcome to inquire or visit our company to discuss cooperation!

Q: Solar energy product development prospects?: 3 local regulations activate the project market, the development of the industry ushered in new growth, the rapid development of solar water heating system engineering market, government policy support. Engineering market is mainly concentrated in the town, the construction of new rural residents in the housing construction, but also for the development of the engineering market provides a new opportunity. To November 2010, some enterprises in the hot water system engineering sales have accounted for the overall sales of 40%, compared with the previous total of only 5% to 15% of the proportion, this growth can be described by leaps and bounds. In the completion of the sale after the maximum sinking, hot water engineering market city building will become the brand of a hotly contested spot, always adhere to the rural areas as the focus of the strategy in the next few years, may turn to the rural market both strategic transformation development market as the leading city.

Q: Buy solar water heater mainly look at what?: Second, liner thickness. The quality of the liner determines the life of the water heater, if the water tank, the water heater will be scrapped. Major brand manufacturers use thickness of not less than 0.5mm of SUS304 food grade stainless steel liner. Argon arc welding is adopted to ensure the service life can reach more than 15 years. Other brands of water heaters in the liner between 0.2mm-0.4mm, the use of a period of time there will be water leakage problem. Therefore, consumers in the purchase of products must ask the thickness of the liner. At the same time, but also beware of patch water tank, the water tank liner is made up of a number of scrap steel belt, the entire inner bladder welding as many as dozens of times
