Indoor Wall Light is Lighting Product installed on interior walls, usually consisting of a lampshade and a bracket. They include Wall Sconce and Vanity Light come in various designs and styles, ranging from modern, traditional, artistic, to minimalist. Indoor wall light can be used to provide basic lighting or to create atmosphere and accentuate interior decoration. Some indoor wall light also come with dimmers, allowing for adjustable light levels as needed. They typically use LED or energy-saving bulbs, thus saving energy and being long-lasting.

Briefly describe the protection of water flow switch in cooling water pump
The water flow switch in the cooling water pump is generally the target slice flow switch, the target of the water flow switch is improperly installed. When the water flow in the cooling water pump is unstable, it is easy to break, and the water flow protection Fault, the simple treatment is to replace the target film, put an end to the water flow switch to move away from the elbow 5 times the diameter of a stable pipe straight pipe. Pump in the water flow switch emergency measures: First look at the cooling tower has no water, water is full, press the one to add water float valve to see if the replenishment, open the cooling water pump, the water fountain is functioning normally, the water flow Is stable, if all normal, you can first cooling water flow switch wiring short, boot. When you can stop, check the water flow switch again, replace or repair it. If no water or water pump no water flow to make up, exhaust, check the valve, check the spare pump check valve. Cooling water pump should pay attention to the place: Shorting cooling water flow switch, if no water boot, the unit will be high pressure protection or compressor overheating protection, compressor overcurrent protection, if these protection failure, it will burn the compressor. Do not short circuit the chilled water flow switch, if the chilled water does not flow, the unit evaporator will freeze in tens of seconds or a few minutes. Water flow switch in the cooling water pump work: Water flow switch with flow control accuracy, no additional resistance to the system, but also on the water pipe diameter does not require interference and no water flow disturbance characteristics, can replace any form of target flow As the flow control of HVAC water system, the switch can avoid the false flow caused by cavitation of pump (the actual flow rate is very big, but the air is mixed with the actual flow rate is not big) compared with the target flow switch. And the scene installation does not affect the flow control value of the differential pressure flow switch, so the water flow switch can be widely used in small and medium sized brazed plate heat exchanger, casing heat exchanger and shell and tube heat exchanger Air-cooled or water-cooled chillers for water flow control and part of the antifreeze protection. The very accurate flow control characteristics of the differential pressure water flow switch can also expose the external water line of the unit to design or improper installation, prompting the installer to exclude installing or changing the piping design.
