  Stainless steel manifold , the most common explanation is not easy to rust the manifold,   stainless steel manifold   with alkali resistance, its surface has a very thin and strong and stable chromium-rich oxide film, to prevent the infiltration of oxygen atoms continue to oxidation, thus casting the stainless steel corrosion resistance. Stainless steel manifold  in water, air, and sodium cyanide and other reducing substances, corrosion resistance will be relatively higher with the chromium content, once there is some reason to destroy the  stainless steel manifold  surface of this film, oxygen atoms will penetrate, the metal in the iron atoms continue to precipitate, the formation of loose iron oxide, stainless steel corrosion resistance will produce sudden changes. So, how should the stainless steel water meter manifold be maintained and cared for? 1、When necessary, soap, weak detergent or warm boiling water can be used to clean and scrub the surface of...

  Water heaters have brought great convenience to mankind and have improved people's standard of living, so water heaters have been installed in every home. The water heater is familiar to people, but when it comes to the water heater   mixing valve , people may be confused. So, today, please allow me to give you some knowledge about the water heater   mixing valve . Water heater  mixing valve  - what is the water heater  mixing valve Role:  Mixing valve  is a valve that mixes hot and cold water, widely used in electric water heaters, solar water heaters and geothermal heating water system. Products are widely used in electric water heaters, solar water heaters and geothermal heating water systems. Users can adjust the mixing temperature of hot and cold water according to their needs, the required temperature can be quickly reached and stabilized, to ensure that the water temperature is constant, and is not affected by changes in water temperature...

  HVAC systems   consist of the cooling/heat source side, the cooling/heat transmission and distribution side, and the end-use side, so energy savings revolve around these three major components in at least 13 ways. Energy saving on the cooling/heating source side of the  HVAC system In the air conditioning system, the energy-consuming equipment on the source side is mainly the refrigeration host and the heat pump unit. Among them, the refrigeration host needs to be matched with perfect control and regulation means; heat pump units, on the other hand, can be used in combination with renewable energy and clean energy to achieve energy saving and emission reduction. The following are six ways to save energy on the source side. Under a certain load rate, try to run more refrigeration units with the highest efficiency, when the energy-saving benefits are not only obvious, but also to provide higher cooling capacity at a certain input power. The COP value is measured to allow ...

  As a result of the escalating conflict between Russia and Ukraine, energy supplies such as natural gas and oil are tight in Europe, and their commodity prices are pushing up. Previously, spot natural gas prices in Europe have been as high as $2,500 per 1,000 cubic meters, and previously German Deputy Chancellor and Minister of Economy and Climate Protection Robert Habeck has said that Germany plans to raise its carbon tax on carbon dioxide to 55 euros per ton in 2025 from the current 25 euros per ton. Clean energy status climbing fast amid energy crisis At present, European countries are entering winter, and the demand for heating is huge. The energy shortage and soaring energy prices have led to tens of millions of families in Europe having "no gas" and "no gas" in winter, making it difficult to meet their immediate heating needs. If we continue to rely on non-renewable energy sources such as natural gas for heating, every winter in the future will be a bitterly ...

  The   thermostat   is used to automatically turn on and off various heating equipment, set and adjust the room temperature, which can automatically adjust the room temperature according to the pre-set program in the case of someone or no one; to make it reach a comfortable temperature. The working principle is to automatically sample and instantly monitor the ambient temperature through the temperature sensor, and the control circuit starts when the ambient temperature is higher than the control set value, and the control return difference can be set. If the temperature is still rising, when it rises to the set over-limit alarm temperature point, the over-limit alarm function is activated. When the controlled temperature can not be effectively controlled, in order to prevent the destruction of the equipment can also stop the equipment to continue to run through the function of tripping. It is mainly used in various high and low voltage switchgear, dry-type transformers,...

  So cold! It's high season again to install   thermostats and actuators ,   actuators   used year after year, about normally open and normally closed, did you figure it out? Let's talk about the basics of  electric actuators . Normally closed type  a ctuato r  working principle. When the room temperature reaches the temperature set by the temperature controller, the positive thermistor (PTC) inside the  electric actuator  starts to work, heating the top rod to raise the valve open, and vice versa, the room temperature decreases, the thermostat is disconnected, the actuator cools down, the top rod shrinks, and the valve closes. Normally open type  actuator  working principle. When the indoor temperature reaches the temperature set by the temperature controller, the positive thermistor (PTC) inside the  electric actuator  starts to work, heating the top rod down to close the valve, and vice versa, the indoor temperature dec...
