Low Pressure Switches and High Pressure Switches in HVAC Systems

Image
  Low pressure switch HVAC systems and high pressure pressure switches are the two basic refrigeration switches in a typical high-grade residential system. It is called high grade because not every refrigeration system of air conditioners and heat pumps has a switch to protect the refrigeration system. Today's focus is on what is a HVAC pressure switch used in a refrigeration circuit and how an HVAC pressure switch protects the system from further damage.   Ⅰ. HVAC PRESSURE SWITCH: INTRODUCTION TO HIGH PRESSURE PRESSURE SWITCH REFRIGERATION   In Lefoo pressure switch manufacturer, The high pressure switch  will stop the compressor circuit if the pressure exceeds the HVAC pressure switch rating. Ratings will vary depending on the type of refrigerant the air conditioner or heat pump uses with the system.   On some air conditioners or heat pumps, this switch is just reset manually. Because if it trips, there's definitely a problem that needs to be fixed before the ...

Application of Differential Pressure Sensor in HVAC System

Image
  As building maintenance needs continue to increase, HVAC systems are no longer adequate for stand-alone use. Whether it is a commercial, retail or industrial building, differential pressure sensors play an important role in monitoring the safety and comfort of the building. When combined with pressure technology, HVAC systems can operate at optimal levels and also improve building maintenance. There are three ways to realize it.   1. THE MAINTENANCE OF THE DIFFERENTIAL PRESSURE SENSOR HVAC  DETECTION AREA   Quality control of the building is fundamental. HVAC differential pressure sensor can closely monitor pressure changes and point out whether there is a dilemma. Pressure drops in the room or through the filter can alert service technicians for maintenance.   Differential pressure sensors monitoring differential pressure in HVAC systems are especially important for critical applications such as the detection of stairwell pressurization, clogged filters or cl...

Application and Common Problems of RO Booster Pump in the System (Water Purifier)

Image
  The main components of RO water purifier pump are generally: front PP cotton, front water inlet solenoid valve, low pressure switch, front activated carbon, middle PP cotton, ro motor pump  for water purifier, RO reverse osmosis membrane, wastewater ratio, backwash electromagnetic Valves, high-pressure switches, pressure barrels, rear activated carbon, gooseneck faucet, etc.   Ⅰ. CLASSIFICATION OF RO BOOSTER PUMPS (BY PERFORMANCE) At present, there are probably: ordinary (second generation) booster pumps, stabilized booster pumps, and self-priming booster pumps. (Note: Mini pumps and RV pumps are not RO water pumps, they are only used for water supply machines).   Ordinary (second generation) RO water booster pump-RO water booster pump without other auxiliary functions;   Stabilized (pressure-limiting) booster water pump-Compared with ordinary booster water pumps, it has an independent pressure relief device. Its function is to discharge the pressure greater t...

The Function and Application of Booster Pump for Water Purifier

Image
  A water pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the liquid energy, and is mainly used to transport liquids including water, oil, acid-base liquid, emulsion, suspoemulsion and liquid metal.   1. INTRODUCTION OF LEFOO BOOSTER PUMP FOR WATER PURIFIER   As the name implies, ro motor pump is a pump used for pressurization. Its main uses are water heater pressurization, low water pressure in high buildings, sauna, bathing and other pressurization, pressurization of insufficient water pressure on the uppermost floor of the apartment, solar automatic pressurization, reverse osmosis purification. Water booster, etc.   Diaphragm pump: Diaphragm pump, also known as control pump, is the main type of actuator, which receives the control signal output by the control unit. Diaphragm pumps are powered by power to change the flow of fluid. The diaphragm pump i...

The Classifications and Working Principles of RO Booster Pump

Image
  RO pump is also known as RO booster pump, RO diaphragm pump, reverse osmosis booster pump, and is a type of DC diaphragm booster pump. It is currently one of the core parts of the water purification industry and household water purifiers.   Ⅰ. DEFINITION OF LEFOO RO BOOSTER PUMP   RO booster pump is the booster pump used in reverse osmosis equipment. It has the functions of self-priming and pressurization and is one of the key and important components of the RO water purifier. The RO booster pump is another important component of the RO membrane in the RO water purifier, which provides the water pressure and water flow required for its work, so as to achieve the purpose of the ro water purifier pump to produce pure water.   Ⅱ. CLASSIFICATION OF RO BOOSTER PUMPS   1. According to RO membrane water production specifications, it can be classified into two categories. The first type is household type. The corresponding pumps of the "national standard RO membrane" ...

Some Questions About Booster Pump for Water Purifier

Image
  Ⅰ. Can the water purifier of the booster pump for water purifier be replaced with a self-priming pump?   It can be replaced. If the source water pressure is above 1 kg, the booster pump can be directly replaced with a self-priming pump; if the source water pressure is below 1 kg (well water), the self-priming pump should be placed in the first stage To the front of the filter element of the water heater, add a self-suction head to the front of the water inlet of the pump, and connect the two lines of the low pressure switch.   Ⅱ. What is the reason for the "gasping sound" inside the booster pump for water purifier ?   There is air flow in the water pump, which is usually caused by low water pressure environment or blockage of the front filter element. Remove the water pump and test it separately to determine whether there is a problem with the water pump. If there is no fault, wait for the air in the pure water machine to be drained. Then you can.   Ⅲ. There i...

  A soda pump dispenser  can get you cold soda water, and RO pumps are optimal for liquid transfer such as soda waters.  

LEFOO WATER PRESSURE SENSOR

Image
  Digital Drinking Water pressure sensors are frequently used for inlet and outlet water pipe pressure measurement in clean water systems at public utilities.   LEFOO WATER PRESSURE SENSOR AND WATER PIPE PRESSURE MEASUREMENT Water pipe pressure sensors  are frequently used for inlet and outlet water pipe pressure measurement in clean water systems at public utilities. Some water systems are fed by the gravity flow of the water, usually, lift stations pump the water to a higher elevation to provide reliable gravity flow. Water pressure in the pump well, water tower needs to be monitored by a water differential pressure sensor to control the predetermined water flow rate at the pump input, which turns off the pump at a minimum flow rate to prevent empty run damage. Also, pump well and water tower that undergoes a large release of water require water supplement.  Pressure sensors for water pumps offer reliable pressure measurement for the pump and the observer can deter...
