  Whether in industry or agriculture, the application of water pump pressure switches in life is quite extensive. Usually, pumps with pressure switches are high pressure pumps. The purpose is to stop the pump after reaching a certain pressure to avoid accidents. So today Lefoo mechanical pressure switch is going to introduce the knowledge about how to adjust the water pump pressure switch .   1. WATER PUMP PRESSURE SWITCH ADJUSTMENT   (1) Loosen the lock nut of the pressure switch. Turn the adjusting nut clockwise or counterclockwise as needed until the pointer points to the desired pressure value. There are two types of pressure switches: mechanical and electronic. The pressure switch is a device combined with an electrical switch. When a certain water pressure is reached, the water pump stops.   (2) The water pump pressure switch  usually has two knobs, which are turned with a flat-blade or Phillips screwdriver. Loosen the lock nut before turning it, and turn ...

  WHAT IS A DIFFERENTIAL AIR PRESSURE SENSOR?   The differential pressure sensor  is a device that monitors the pressure changes of the medium at two different positions. (For example, the pressure of the raw water before filtering will be higher than that after filtering. When the water pressure at the low pressure side suddenly increases, it usually means that the filter is clogged or damaged ).   For air differential pressure transmitter   manufacturers, The positive and negative pressure ends are separated by a stainless steel diaphragm, so both pressure chambers are available to a chemical aggressive fluid, and the measured pressure differential  is passed to the silicon wafer through the isolation diaphragm and filled silicone oil, generating a milliampere-level electricity current signal, which is collected by the pressure sensitive sensor and the circuit board followed by a temperature compensation to achieve accurate measurement of the differential...

  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 for HVAC  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 building pressure sensors  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 duct pressure sensors  monitoring differential pressure in HVAC systems are especially important for critical applications such as the detection of stairwell ...

  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 aqua 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 gr...

  Most Reverse Osmosis membranes have ideal minimum pressure such as 50 psi or 60 psi.  When the pressure is insufficient the RO system will generate less drinkable water at a low purify effect. The 150 gpd ro booster pump will increase 75 psi pressure. The RO pump can be used in a water purifier of 150 gallons per day. The RO Booster Pump 150 gpd can generate more high-purity freshwater with less rejected water. 150 gpd ro booster pump  are commonly used either to pressurize water from an atmospheric tank, to deliver purified water to a specific point of use, or simply to increase pressure when required. This ro booster pump 150 gpd  is designed for both intermittent duty and continuous operation.   As a professional peristaltic hose pump  supplier, lefoo  trys our best to provide good products and service for you.
