Rotating joint for solar energy

Solar specific rotary joints are mainly used as collectors in solar thermal oil boilers. Solar thermal oil boilers are boiler systems that use solar energy to heat thermal oil and can stably output it. They are mainly composed of three parts: solar collectors, accumulators, and thermal oil boilers.

The rotary joint of solar photovoltaic power generation equipment belongs to the category of high-temperature rotary joints. It converts solar energy into radiant energy to heat the fluid medium, which is transmitted through a dedicated rotary joint to a heating tank or tank with a water tank, and converted into steam energy to drive a steam turbine for power generation; According to the fluid medium, it can be divided into thermal oil rotary joints, thermal silicone oil rotary joints, and high-temperature molten salt rotary joints. The flange and welding connection methods can be selected according to the equipment operating conditions; The entrance of the transmission medium can be freely selected to enter through the side or rear according to the working conditions.
