The most commonly used home heating is a gas wall-mounted boiler, which heats water through the boiler and pressurizes the water pump to form a hot water cycle to complete the heating process. Gear drive shaft vacuum heat treatmentThere are three main types of gas-fired boilers on the market, casing-type gas-fired boilers, plate-replacement gas-fired boilers, and condensing gas-fired boilers. Although gas-fired boilers still emit exhaust gas, they are still a common heating method for some low-income families.Aluminum alloy vacuum brazing process Plate exchange boiler The difference from the casing boiler is that when using domestic water, the boiler is specially equipped with a heat exchange plate, which cuts off the heating water circuit through the switching of the electronic three-way valve in the boiler, so that the heated hot water forms a heat exchange in the boiler. CTS antenna vacuum brazingSmall cycle, through the plate heat exchange to domestic water. Therefore, in terms of constant water temperature, plate-exchange boilers have certain advantages, and their service life is longer than that of jacketed boilers.Vacuum heat treatment of 20CrMnTi steel
