Changzhou Baixiang pressure controller includes pressure switches and pressure sensors,They can be used not only for the protection and control of high and low pressures in refrigeration systems such as household, commercial, and automobile air-conditioning, but also for air compressors, air pumps, water pumps, sprayers, hydraulic machines, and other equipment that requires pressure control.
When the gas compression refrigeration system is working, the inlet of the compressor discharge port --- condenser --- expansion valve (capillary tube) belongs to the high pressure part.From the outlet of the expansion valve-the evaporator-the suction port of the compressor belongs to the low pressure part.
Different air compressor pressure switch has different adjustment methods.One is the switch with fixed pressure , only adjust the automatic shutdown pressure or the highest pressure, This kind of pressure swith always has two one-letter Screwdriver Adjustment Knob,and the two knobs must be adjusted together or air compressor will be frequent action and burn out the appliances. Another one is one
However, in the current pressure switch application market, in addition to the demand of positive pressure, there is also the demand of negative pressure;However, there are few pressure switches with negative pressure induction at present, and even if they have, they are complicated in structure, the product quality is unreliable or the application pressure range is very low.
pressure monitoring is recognized by the air-conditioning pressure switch.But what is the air conditioner pressure switch? What is the working principle of the air conditioner pressure switch?
Mainly used in air 、oil、water and refrigeration systems to prevent the pressure in the system from being too high or too low to ensure that the air conditioning and refrigeration system is always within a safe working pressure range.
The low pressure switch is the first protection setting on the pure water machine.Its function is to start the water purifier when the water pressure entering the reverse osmosis water purifier reaches the preset starting pressure.When the water pressure entering the pure water machine is too small or when there is no water entering the pure water machine, the low pressure switch will not start an
