Solar engineering coupling box Also known as solar engineering coupling box Solar engineering coupling box Solar engineering collector box. An important part of the solar water heating project, used to collect and store solar heat. Modular installation. Originated in China, and the rapid development of the Chinese market, a large number of applications in solar water heating projects, solar water heating projects in the past two years by more and more countries to accept, more than ninety-five percent of the world's engineering coupling box are produced from the Chinese market. Combined-box solar water heating system is a semi-immersible solar water heating system that can be combined with conventional energy sources to realize 24-hour continuous hot water supply by combining tube collector array, hot water storage tank, auxiliary heating system, intelligent control system, piping and circulatory system, and can be used to set the water temperature at will according to the need and realize the semi-immersible solar water heating system with conventional energy sources. The vacuum collector tube accepts solar radiation, converts the collected solar radiation energy into heat energy, and gradually heats up the water in the vacuum tube and collector; when the water temperature in the collector reaches the set temperature, the hot water in the collector is transported to the hot water storage tank with heat preservation function through the temperature sensor, temperature controller, solenoid valve, water pump and other equipments, and is stored in the hot water storage tank with heat preservation function, and at the same time automatically replenishes the cold water. When the water level reaches the upper limit of the hot water storage tank, the temperature controller starts the corresponding equipment, and automatically turns the system operation mode into a constant-temperature cycle, forming a cycle between the collector and the water tank, continuing to utilize the solar radiation energy, and further increasing the water temperature of the water tank. Since the domestic mature solar energy equipment are household solar energy production equipment, and solar energy engineering combined box collector production without special equipment. Due to the limitation of technology and equipment, the engineering coupling box collector can either guarantee fully automatic welding but not suitable for the reasonable size of engineering coupling box, or suitable for the reasonable size of engineering coupling box but can only be manually welded. In order to solve this contradiction, the production technicians of Liaocheng Longpu Solar Engineering Co., Ltd, a subsidiary of Longpu New Energy, combined with the automation control, machinery manufacturing, welding three professional companies after ten months of design and testing, and spent more than one million yuan to invest in the three sets of design solutions finally succeeded in finding a solution to create an assembly line and a full set of fixtures and molds. With the beginning of October to complete the commissioning for trial operation. This assembly line outer skin, inner liner automatic shearing, automatic molding, automatic welding of all welding seams, production efficiency significantly improved, and ensure the stability of product quality. After put into production, it can realize the annual output of 250,000 units of joint box. The product has been through the stability test, destructive testing and other procedures to confirm product quality in line with the design requirements, ready for formal operation and production in early 2009. The formal operation of this production line has put an end to the history of no special production equipment for coupling box collector in China, and further consolidated the company's market position as a professional manufacturer of coupling box, and further laid a foundation for the marketing concept of "scale production, affordable sales, and creating the most cost-effective coupling box collector" for the manufacturing of coupling box of Liaocheng Longpu Company.
