Solar water heaters convert sunlight into heat and heat water from low temperatures to high temperatures to meet the hot water usage in people's life and production. Solar water heaters according to the structure is divided into vacuum tube solar water heaters and flat-panel solar water heaters, vacuum tube solar water heaters, accounting for 95% of domestic market share.

Temperature control heat cycle Solar water heating system in a collector temperature detector and water temperature sensor, solar collector system absorbs solar radiation, the collector temperature rises, when the collector temperature and water temperature difference between tank temperature t set value, the detection system Issue a command, circulating pump will be the central water heater cold water input collector, the water is heated and then back to the tank, the water tank to set the temperature. 2. To warm the pipe circulation system Add a hot water circulation pump, through the controller to warm the pipe circulation. When the water temperature reaches the set temperature, automatically start the warm circulation pump, the high temperature water through the floor heating coil in the room to circulate, so that the indoor temperature continues to increase. When the water temperature of the water tank is lower than a certain set value, it automatically stops heating the circulation pump of the pipeline.
Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.
Surface grinding is the most common of the grinding operations. It is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look by removing the oxide layer and impurities on work piece surfaces. This will also attain a desired surface for a functional purpose.

The surface grinder is composed of an abrasive wheel, a workholding device known as a chuck, and a reciprocating or rotary table. The chuck holds the material in place while it is being worked on. It can do this one of two ways: ferromagnetic pieces are held in place by a magnetic chuck, while non-ferromagnetic and nonmetallic pieces are held in place by vacuum or mechanical means. A machine vise (made from ferromagnetic steel or cast iron) placed on the magnetic chuck can be used to hold non-ferromagnetic workpieces if only a magnetic chuck is available.
Factors to consider in surface grinding are the material of the grinding wheel and the material of the piece being worked on.
Typical workpiece materials include cast iron and mild steel. These two materials don't tend to clog the grinding wheel while being processed. Other materials are aluminum, stainless steel, brass and some plastics. When grinding at high temperatures, the material tends to become weakened and is more inclined to corrode. This can also result in a loss of magnetism in materials where this is applicable.
