    How to choose a peristaltic pump for you

    The choice of peristaltic pump is mainly affected by four aspects: 1.Hose inner diameter When the speed is the same, the pump flow of the hose having a large inner diameter is greater than the pump flow of a hose having a small inner diameter. 2. Flow range Traffic is an important pump parameter, determined by many factors, for example: Hose inner diameter -------- The larger the inner diameter, the greater the flow rate Pump head speed -------- The larger the speed, the greater the flow rate Pulsation size -------- The larger the pulsation, the greater the traffic 3. Pulse Pulsation is an important selection parameter of a peristaltic pump, which is determined by many factors: Traffic range ------- The larger the flow, the greater the pulsation Pump cavity ------- The larger the pump chamber, the greater the pulsation Rotor speed ------- The faster the speed is pulling, the greater Flow density ------- The higher the density, the greater the pulsation (Note: Value above the parameters. In the reasonable range of normal operation) 4. Treatment of liquid When selecting a peristaltic pump, the nature of the application environment and liquid is also a very important reference factor.

    What is the principle of peristaltic pump?

    The principle of peristaltic pump operation is that there is always a runner that keeps the pump tube in the pump. When the peristaltic pump shaft rotates continuously, the runner will rotate the squeeze hose once, but the runner in the peristaltic pump appears. The two runners simultaneously squeeze the hose, so the hose is alternately squeezed as the runner alternates. When the wheel is turned to the hose outlet, the squeeze received by the hose disappears instantaneously because the wheel loosens the hose. At this time, because the hose is not squeezed, it will immediately return to the non-extrusion state, at which point we will see a sudden decrease in the fluid flow at the hose outlet. At the same time, when the hose rebounds, the volume inside the hose suddenly increases, and the other roller in the pump squeezes the inlet of the pump. The increased volume will automatically suck back from the outlet. The fluid flow at the outlet also suddenly decreases, so that a pulse occurs.

    How to Operate a Pool Pump & Filter

    Components of a swimming pool are highly interdependent. Without proper operation of each element, water quality and comfort degrade and damage may occur to other components. The basics of pool design are consistent whether applied to in-ground or above-ground pools. The system is engineered to keep a large volume of water properly filtered, circulated, heated and treated with disinfecting chemicals. The two most critical elements in any pool system are the pump and the filter. Pool Circulation A pool pump circulates water from the pool through the filter and back to the pool. The pool pump is generally located next to the filter in a concrete pit or recess below the water level of the pool so water flows by gravity to the inlet of the pump. Water entering the pump input first passes through a strainer basket in the pump housing to remove debris. Leaving the pump, the water circulates through the filter and then the heater, if one is installed. Water is reintroduced to the pool through return jets embedded in the walls of the pool. In a regularly utilized pool, the pump may run continuously to provide consistent filtration and circulation. To conserve electricity, many residential pool pumps are connected to timers so the circulation is limited only to hours of the day when the pool is likely to be used. Priming The Pump And Filter Occasionally a pool pump may lose its prime and air may enter the system, interrupting circulation of water. The most common cause is evaporation, causing the pool water l

    How to Prime a Diesel Injector Pump?

    Injection pumps play an integral role in the operation of diesel-powered vehicles. The part allows diesel cars and trucks to run by delivering an exact amount of fuel, under very high pressure, to each injector at a specified time interval. As the fuel is delivered from the injection pump, each injector disburses the fuel into the motor's cylinders, where it combusts, and keeps the motor running. During routine maintenance, such as fuel filter replacements, you may need to prime the injection pump to remove air from the fuel system. Loosen the nuts connecting the injectors to the motor head. This will allow any air between the injection pump and injectors to exit the system during priming. Insert the key into the ignition. Turn the key to the "on" position and turn it slightly toward the "start" position to bump the starter. Release the key after approximately one to two seconds so that it returns to the "on" position. Listen for the vehicle's electric lift pump to begin transferring diesel from the fuel tank to the fuel filter housing and, in turn, the injector pump. The lift pump will sound like a buzzing coming from the fuel tank. If you do not hear the lift pump working, bump the engine a second time. Work with a partner to watch for fuel coming from the injector lines where you previously loosened the connection nuts. Re-tighten the nuts when fuel begins to flow out of the injector lines. At this time, your injector pump is primed with fuel. With the injector lines re-connected to the head, crank the vehicle and allow it to begin running.

    Application of Mini Peristaltic Pump in Automatic Washing Machine

    Application of micro peristaltic pump in fully automatic washing machine: Large automatic washing machines need to add various chemical agents quantitatively and regularly to complete the entire automatic washing process. Because the hose of the peristaltic pump can withstand various chemicals, there is no possibility of cross-contamination, it has good sealing, and can accurately meter and pump viscous liquids. It is only suitable for this task to be completed by the peristaltic pump. Because the detergent has a certain viscosity, when choosing a peristaltic pump, it is necessary to choose a peristaltic pump with a relatively thick hose wall thickness as much as possible, so that the performance of the peristaltic pump can be better reflected. Using a peristaltic pump to complete this work can realize automatic and accurate measurement of how much detergent should be added according to the amount of clothing, so as not to waste detergent or lack of detergent, which reduces environmental pollution and water waste. It also saves the cost of manual addition, and washing machines with detergent added by peristaltic pumps will be more and more recognized by users and become an indispensable part.
