How to Adjust the Water Pump Pressure Switch?

Image
  How to Adjust the Water Pump Pressure Switch? 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 ...

  LEFOO 100 GPD RO PUMP RO booster pump 100 GPD Pressure Booster Pump / Self-Priming Pump Work Flow: 0.98L/min or 1.05L/min Work Pressure: 0.5Mpa=70Psi Noise Level: ≦45db / ≦50db Max Current: ≦1.4A / ≦2.1A   RO Booster Pump 100 gpd Self-priming RO Booster Pump 100 gpd   The water purifier manufacturers can employ 100 gpd pump  as pressure boosting devices in their products. The reverse osmosis system can remove 98-99 % of contaminants in the tap water or static water resource. The ro booster pump 100 gpd  can increase the water production efficiency by 70 psi pressure feeding.   REVERSE OSMOSIS OF RO BOOSTER PUMP 100 GPD Reverse Osmosis is the reverse process of natural osmosis. Solutions with low salinity and low density have a natural tendency to migrate to solutions with high salinity and high density. The reverse osmosis membrane of the RO water booster pump divides the water into two pass way, the permeated water passes through the RO membrane to the c...

HOW TO IMPROVE THE WORKING EFFICIENCY OF A PERISTALTIC PUMP?

Image
  Relevant people in the industry said that as pumping fluid equipment, high productivity must be emphasized, especially in the era of high-speed production. So, how to make the peristaltic pump most effective when it is working? You can refer to the following:   1. Reduce the speed of the peristaltic pump as much as possible   The flow of the peristaltic pump is caused by the rotation of the pump head. The faster the rotation, the shorter the use time of the pump. Therefore, if you want the pump to last longer, you can choose the pump with the largest possible pipe diameter to reduce the speed of the peristaltic pump. Lefoo, one of the the leading peristaltic pumps manufacturers,  can provides DC peristaltic pump and stepper motor peristaltic pump that you can choose.   2. Selection of peristaltic pump pipe   It is recommended to use special pipes for peristaltic pumps for the pump head and ordinary pipes for the remaining connections. The squeeze tube use...
