WHAT ARE THE ADVANTAGES OF PERISTALTIC PUMPS USED IN WATER QUALITY SAMPLERS?

Image
â… . THE WORKING PRINCIPLE OF PERISTALTIC PUMP   A peristaltic pump is like squeezing a hose full of fluid with your fingers. As the fingers slide forward, the fluid in the tube moves forward. The peristaltic pump also uses the same principle, except that the finger is replaced by a roller.   The fluid is delivered by alternately squeezing and releasing the elastic delivery hose of the peristaltic pump. Just like squeezing a hose with two fingers, as the fingers move, negative pressure is formed in the tube, and the liquid flows along with it.   With the wide application of peristaltic pumps, there are more and more peristaltic pump manufacturers .   â…ˇ. WHY DOES THE WATER QUALITY AUTOMATIC SAMPLER USE A PERISTALTIC PUMP?   In the process of realizing water quality sampling, the water pump used by the automatic water sampler is in most cases a peristaltic pump. what is the reason?   1. No contamination-the liquid only touches the pump tube of the peristaltic p...

INTRODUCTION TO THE DESIGN ADVANTAGES AND CLASSIFICATION OF PERISTALTIC PUMPS

Image
  In the past, peristaltic pumps were almost exclusively used in laboratories. But after redesigning, its flow rate and pressure have been improved. Now, a large number of peristaltic pumps have been successfully applied in the field of chemical process control and production.   The popularity of the peristaltic pump can be attributed to its design, which uses a motor to drive a set of rollers to rotate. The rollers successively run over the soft peristaltic pump tube, compressing and releasing it repeatedly. This squeezing action creates a vacuum, sucking fluid in and passing through the peristaltic pump tube, thereby completing the pumping process. Because only the peristaltic pump tube is the water-passing part, maintenance and cleaning are simple and convenient. And there are more and more peristaltic pump manufacturers .   â… . DESIGN ADVANTAGES OF PERISTALTIC PUMP   The design and configuration of the peristaltic pump can make the conveyed fluid always flow in th...

COMMON TROUBLESHOOTING AND SELECTION OF RO BOOSTER PUMP

Image
  1. WHAT IS RO BOOSTER PUMP The main function of the RO booster pump is to pressurize the water. Electric appliances such as water purifiers have too little water yield because of the low water pressure due to the low water supply pressure of the tap water, which can be improved by installing a booster pump.   2. COMMON TROUBLESHOOTING OF BOOSTER PUMP FOR WATER PURIFIER   When the booster pump for water purifier is running, there may be many reasons that cause the booster pump to not work normally. Common faults are:   (1) The seals of the driving piston are severely worn, resulting in air leakage on the upper and lower sides of the piston; (2) The reversing valve is not clean or cannot move normally due to the damage to the seal; (3) The connection between the two pistons in the booster pump is damaged, the split pin falls off, and the two piston rods are misaligned, which makes the piston rod unable to rotate; (4) Air leakage occurs in the seals of the booster cyl...

USES AND APPLICATION RANGE OF THE PERISTALTIC PUMP

Image
  INTRODUCTION OF THE PERISTALTIC PUMP   The peristaltic pump is a type of pump that realizes fluid delivery by squeezing a hose. Usually, the pump with a pressure higher than 0.4Mpa is called a hose pump, and that with a pressure lower than 0.4Mpa is called a peristaltic pump. Peristaltic pumps are divided into plug-and-play complete sets of peristaltic pumps and OEM peristaltic pumps for OEM customers, equipment manufacturers and machinery manufacturers. It is suitable for independent work, such as in the laboratories, industrial production, etc.   From the perspective of product function, the main purpose of the peristaltic pump is: quantitative or metered delivery, and quantitative or metered distribution. Therefore, peristaltic pumps can be selected to meet the application requirements for all application scenarios that require quantitative delivery and distribution.   The use of the pump can also be simply considered from the perspective of the working state of...

THE WORKING PRINCIPLE OF PERISTALTIC PUMP

Image
  1. THE WORKING PRINCIPLE OF PERISTALTIC PUMP   The peristaltic pump is a commonly used equipment, which is composed of a driver, a pump head and a peristaltic pump hose. It is a liquid delivery equipment that can control the flow rate.   The gland and roller of the pump compress the hose, and the hose between the two rollers presents a pillow shape. When the roller rotates, the elastic delivery hose is alternately squeezed and released to pump fluid. With the rolling of the rollers, the elasticity of the hose will restore the pump tube to its original shape, forming a negative pressure at the pump inlet, which promotes the flow of liquid and makes it fill the pipeline to achieve the purpose of transmission. The pillow-shaped volume formed therein has a certain relationship with the wall thickness, inner diameter of the peristaltic pump hose and the size of the roller. The flow rate of the pump depends on the speed of the pump head and the wall thickness of the hose. In ...

DIFFERENTIAL PRESSURE SENSOR VS DIFFERENTIAL PRESSURE TRANSMITTER

Image
    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 ).   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 differential pressure 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 pressure.   The pressures that silicon experienced are converte...

THINGS YOU SHOULD KNOW ABOUT MISTING SYSTEM

  Misting systems are referred as to  "Fogging Systems" or "Spray Cooling". All misting systems fit in the category of misters, and every one of them works the same way. All misters work with evaporative cooling - the natural cooling effect that happens when water evaporates in warm air. They all work beautifully in dry weather.   A misting system for a greenhouse could consist of a reservoir, a 300 GPD RO booster pump, high-pressure pipes,1/4 inch quick connect bulkhead unions,1/4 inch quick connect tees,1/4 inch quick connect elbows, and misting nozzles.   Misting System is an optimal outdoor cooling method that uses a fine spray of water to cool you, your family, your guests, your customers, your workers, teammates, employees… even your animals -- pets or livestock.   A commercial misting system can be consist of an 800 GPD pressure boosting pump, flexible tubing, host fitting,3/8 inch quick fittings, high-pressure pipes, Cantilever Umbrellas, the pros of add...

PRESSURE SENSOR VS PRESSURE TRANSMITTER

Image
    Definition of a Pressure Sensor:    The literal definition of a pressure sensor is a device that undergoes a physical force on a certain area and translates it to a basic energy signal. The sensor consisting of a pressure-sensitive silicon wafer, for a liquid pressure sensor, requires a diaphragm and filled oil, and PCB to convert information from the silicon wafer into an output signal. The working principle of the pressure sensor is based on the Wheatstone bridge. The basic energy signal of a pressure sensor can be 4-20 ma.   Definition of a pressure Transmitter:   The pressure transmitter consists of a pressure sensor that uses additional electronics to compensate for linearity deviations and temperature errors, outputting measurement results as higher-level signals. Every transmitter is measured over the entire pressure and temperature profile and compared to the desired signal span. The higher energy signal of a pressure sensor can be 0-10 V, 0.5-5...
