The peristaltic pump is one of the pump products that can transfer solid-liquid mixture, but peristaltic pump transmission of the solid-liquid mixture is limited, some problems should be paid attention to in the use. The solid components contained in the liquid-solid mixture can be divided into two types: hard particles and flexible particles. When transporting the solid-liquid mixture with hard particles, if the specific gravity of hard particles is relatively large and easy to deposit, the transmission with a peristaltic pump should run at a higher speed, because this kind of mixture is easy to accumulate at the inlet pipe of peristaltic pump, causing the blockage. Agitator shall be installed in the container containing the solid-liquid mixture to ensure that the solid particles are not precipitated and evenly distributed so that they can be uniformly extracted by the peristaltic pump. In addition to the diameter of hard solid particles is limited, usually, the max particle diameter can not exceed 10% of the hose diameter. When the transmission of hard solid particles of uniform size, choose a thicker pipe, make the particle diameter less than 5% of the hose diameter or lower proportion, otherwise, there is the possibility of the pump head being stuck by solid particles.

Bromine is a dark reddish-brown liquid. It is also a liquid nonmetallic element at room temperature. It has a pungent smell and is highly corrosive. It is mainly used for the production of bromide, as a general analytical reagent, oxidant, absorber for ethylene and hydrocarbons, and as a brominated agent for organic synthesis. Since bromine is an organic solvent, it is highly corrosive. When transferring bromine, the peristaltic pump matching silicone tube cannot transfer bromine, because bromine will corrode the silicone tube. Currently available for transmission of bromine and compatible with peristaltic pumps, only a rubber-lined Teflon hose lined with teflon material, resistant to expansion and cracking, suitable for almost all solvents. And teflon can also transport bromine. Because the teflon pipe is too hard to be used with a peristaltic pump, teflon lined hose can only be used, that is, teflon lined hose. 1.Start up and preheat the hose As the teflon lined hose is harder than the silicone tube, it is necessary to squeeze the teflon lined tube at low speed to soften it at the beginning of startup. Or at low-speed pump head extrusion rod open, slowly press the extrusion rod down, while press to observe whether the hose is evenly squeezed. Wait until the hose is evenly squeezed, yo

Microfluidic pump, hose pump, tube pump all belong to peristaltic pump. But, Microfluidic pump and hose pump not exactly the same. In microfluidics, it is often desirable to minimize the circulating volume of fluid. Traditional pumps require a large volume of liquid external to the microfluidic circuit. This can lead to problems due to dilution of analytes and already dilute biological signalling molecules. For this reason, among others, it is desirable to integrate a micro-pumping structure into the microfluidic circuit. Presented in 2008 a pneumatically actuated peristaltic micropump which eliminates the need for large external circulating fluid volumes. If you have any questions about the hose pumps, please feel free to consult us chuangrui precision pump.

The peristaltic pump is a new type of industrial pumps, widely used in pharmaceutical, food, chemical and other industries, transport some with sensitivity, viscous, highly corrosive, with grinding action, high purity requirements, and contains a certain particulate material medium. In the pharmaceutical field, the peristaltic pump is highly popular for its high precision and low flow rate, which can transfer highly viscous liquids, non-polluting, and non-corrosive pump tube types. Experts said that when customers choose a peristaltic pump, whether it is an industrial peristaltic pump, or laboratory peristaltic pump, or liquid transmission peristaltic pump, decided to work efficiency or peristaltic pump transmission accuracy, and decided peristaltic pump transmission accuracy requires good peristaltic pump body, peristaltic pump head, and hose. Wherein, peristaltic pump peristaltic pump hose is the main working part, its performance directly affects the accuracy, stability peristaltic pump flow. The impact peristaltic pump hose life there are many factors, such as the running speed of the pump head, the hose material and the pump head roller and the arc between the pressure tube ga

After the fluid enters the peristaltic pumps pump head is accumulated between the two rollers, forming a"fluid pillow." Followed by a brief break, because the back section of the pump tube has been blocked roller, again forming a"fluid pillow."So the cycle, they form a pulsating, rather than smooth continuous fluid. If you do not want this pulsation, can be used peristaltic pumps tube locking degree adjustable pump head, which can reduce the degree of pulsation by 25%, because it makes the degree of drying fluid between the pillow slowed. However, some applications of peristaltic pumps pulsation generated more restrictive. For them, a 25% reduction in the degree of pulsation is not enough.

Mainly refers to the peristaltic pump clamp optimization The adjustment steps are as follows: 1. Install the peristaltic pump clamp and put it in place. (it is better to install all the pump clamps to avoid the inclination of the pump clamps. ) 2. Through the plasma control panel, set the atomizing gas pressure as 30psi. 3. Put the sample tube into distilled water and observe the flow of distilled water.

Compared with a piston pump, a peristaltic pump has the following characteristics Function: The peristaltic pump can provide a wide range of filling volume, 0.1ml ~ 500ml. Of course, it depends on different hose diameters. When changing the filling volume, you only need to replace the hose with the appropriate diameter, and you don't need to purchase and reserve the pump body compatible with other filling volumes.

Peristaltic pump and diaphragm pump are two relatively new types of pumps. Now it is the rising market of these two pump products, and they are constantly seizing the market of other products. Now we will explain in detail the differences between the peristaltic pump and diaphragm pump. 1. Diaphragm pump needs air pressure to drive, and the air pressure also needs part of the cost. For the air source, the consumption of the diaphragm pump is much more than that of the peristaltic pump. 2. Diaphragm pump is drive

Fermentation tanks are widely used in industrial production. Various experimental fermentation tanks and factory-scale production fermentation tanks are widely used in industrial production. These fermentation tank devices play a very important role in biological fermentation. Fermentation tanks are used in factories. In each process of the production process, various trace elements or catalysts need to be continuously added and supplemented to control the state of the fermentation broth. Through these supplementary substances to precisely control the fermentation process. The accuracy of the added trace elements will greatly affect the progress of the fermentation process and the quality of the final product. Generally, various pumps are used in fermentation tanks to automatically and continuously add liquid. Among them, peristaltic pumps are widely used in fermentation tanks. The delivery accuracy and long-term reliable operation characteristics of peristaltic pumps determine the stability and reliability of the output liquid. It also plays a particularly important role in the fermentation process. Manufacturers of fermentation tanks, therefore, need to pay special attention to the selection of peristaltic pumps and the matching of models. There

The explosion-proof peristaltic pump is like squeezing a hose full of fluid with your fingers. As your fingers slide forward, the fluid in the pipe moves forward. The principle of the peristaltic pump is the same, but the finger is replaced by the roller. Now we will explain in detail how to reduce the pulsation amplitude in the process of peristaltic pump pumping. (1) The pump head with an adjustable locking degree of pump pipe can slow down the flow interruption between fluid pillows and reduce the pulsation by 25%. (2) But in some applications, the pulsation produced by the peristaltic pump is more strictly limited, and the reduction of 25% pulsation is not enough. In this case, the other four measures can be considered to further reduce the pulsation The pump head with staggered locking and more rollers is adopted;

Peristaltic pump silica gel tube is also called peristaltic pump hose. It uses the platinum vulcanization process for vertical extrusion molding, which eliminates the precipitation problem often encountered in other vulcanization methods. There is a great difference between the peristaltic pump hose and the ordinary silica gel tube. 1, because the silica gel tube is always squeezed in the process of use, so it should have the characteristics of not easy deformation and high resilience. The silica gel tube used by the Leifer pump is made of the high-purity wear-resistant silica gel material, which has the characteristics of high transparency, high-temperature resistance, and 90% resilience. 2, pump transmission characteristics for precision transmission, for peristaltic pump silica gel tube diameter and wall thickness size requirements are very precise, because the size of the inner diameter directly affects the flow rate of pumping liquid, thus affecting the size of the pump flow;

A peristaltic pump head can adapt with a variety of pump tubes, and each tube with different inner diameter of the pump tube will cause different flow rate. As for the same peristaltic pump head, the inner diameter is larger, and the flow rate for each turn is bigger, on the contrary it is smaller. In the ideal state does, without taking into account the impact of liquid viscosity on the flow, the peristaltic pump generate the same flow rate each tur. Then if the pump generate 10ml each, the flow rate is 10ml / min, if the pump turn N /min, the flow rate is 10N/min. Of course, there are some differences between the reality and the ideal condition, as below 1.The

The peristaltic pump can be called a constant flow pump, which is a kind of constant flow pump, because the conveying precision can reach up to 0.5%, so it plays a role of constant current. The specific analysis is as follows: Why is the peristaltic pump called constant flow pump? The peristaltic pump can be called a constant flow pump, which is a kind of constant flow pump, because the conveying precision can reach up to 0.5%, so it plays a role of constant current. The specific analysis is as follows: The principle of the peristaltic pump is that the runner presses the pump tube and rotates to push the fluid in the tube forward to generate fluid flow, just like using two fingers to squeeze a hose filled with liquid, with the fingers When moving, a negative pressure is formed in the tube and the liquid flows. Therefore, the peristaltic pump is a positive displacement pump. The liquid in the pump tube is pushed out by the runner of the pump head. After the runner leaves, the pump tube will stably rebound and suck in new liquid. Our peristaltic pump head produces a constant flow rate per revolution, and the flow rate will increase by the same amount every time the speed is increased per unit time. Therefore, the flow rate generated by the peristaltic pump at a specified rotationa

SPME is a new technology of sample pretreatment. SPME is one of the best sample pretreatment methods at present. It has the advantages of simplicity, low cost and easy automation.,Now SPME has been widely used in environmental protection and water quality treatment, clinical medicine, public security case processing, national defense and other fields. The SPME device has a telescopic rod in the needle, and a molten quartz fiber is attached to the SPME device, and its surface is coated with chromatographic stationary phase. Generally, the molten quartz fiber is hidden in the needle, and when necessary, When needed, push the sampler push rod to allow the quartz fiber to protrude from the needle. Solid phase microextraction is divided into two steps. The first step is extraction. The needle is inserted into the sample container and the quartz fiber is pushed out to extract the sample.The second step is to insert the needle into the chromatogram injector in the sampling process, push out the quartz fiber, and complete the steps of desorption and chromatogram analysis. Of course, in the process of collecting and bottling, the sample liquid can also be collected under the action of peristaltic pump.

Peristaltic pump safe and healthy, stable operation, adjustable pressure, can handle most viscous fluid, excellent performance in pharmaceutical and food bottling. Chuangrui's customers in a pharmaceutical factory in shandong province are comprehensive pharmaceutical enterprises mainly engaged in the production of large-capacity injection, and the filling production of various kinds of pharmaceutical liquid, including sensitive preparations, viscous preparations, corrosive preparations and so on. Customer example: The customer USES automatic filling equipment and plunger pump (10 heads) to fill ampoules with the volume of filling liquid in the range of 1ml ~ 20ml, 10 bottles/time, and the single filling time is between 0.5 and 1.5 seconds. The plunger pump has a good effect, but when the speed is too fast and the liquid viscosity is large, the plunger pump body is easy to be damaged during repeated extraction and filling. In view of this situation, the pharmaceutical company procured peristaltic pump for production.

Peristaltic pump is powered by air pressure to transport liquid, not only ordinary liquid and granular liquid, but also air.In some cases. peristaltic pumps can also deliver pure solid material.First, the solid material must meet several requirements before it can be transported through the peristaltic pump: 1. The solid to be transferred must have natural tightness, that is to say, in the natural state, the solid to be transferred in any section of the hose has air tightness or very low air leak rate, which requires the solid must be in the state of fine powder. 2. The solids to be transferred must be self-lubricating. If the friction between the transmitted solids is relatively large, it is easy to form a tight accumulation of solids, resulting in the blockage of the transmission pipeline. 3. Since the fluidity of solid material is far less than that of conventional liquid, the solid to be transmitted should also meet the condition of low density, so as to minimize the transmission resistance of solid and avoid the accumulation and blockage of solid. Daily use of printer toner is to meet the above three conditions, so peristaltic pump can be applied to toner transmission. There are some differences between toner and liquid transport:
