1, according to the flow parameters to query
You can be based on the model of the pump head and hose, directly get the flow rate corresponding to the rotational speed. Or find the amount of liquid transferred per revolution, according to the flow rate formula, calculate the required flow rate corresponding to the rotational speed, and then adjust the speed that is the corresponding flow rate. This method can roughly set the speed and flow rate, easy to operate, commonly used in many types of pumps.
2, calculate the rotational speed and flow of the corresponding relationship
Set any speed n1, determine a certain time t1 transmission of the actual volume of liquid Q1, according to a = Q1/n1 calculated flow coefficient a, and then according to the formula n2 = Q2/a calculated the required speed n2, adjust the speed so as to get the required flow rate of L1. This method of flow rate is more accurate, but the operation is complex, applicable to the flow rate and quantitative accuracy requirements of higher. Higher requirements for the flow and dosing accuracy of the pump, when the external operating conditions change or a long period of time when running, the need for timely flow correction, in order to maintain a high degree of accuracy of the flow.
3, directly enter the flow parameters
Peristaltic pumps are high-definition LCD touch-screen display and operation, simply select the pump head and hose models, and then directly enter the flow parameters can be. This method of flow obtained by high precision, only according to the prompt can be completed, convenient operation, high degree of intelligence. When the working conditions change or when running for a long time, it is necessary to carry out timely flow correction in order to maintain high flow accuracy. The pump and flow sensor form a closed-loop system, which can fully automate the real-time flow correction and realize the stable flow transmission for a long time.
Expansion of knowledge
Knowledge points, How to make peristaltic pump flow Transportation to become more accurate
Peristaltic pump as a new industrial pump, because of its low maintenance costs, long use and many other advantages, more and more received by the industry's welcome, but because the first contact is not very good at using, resulting in the transfer of the situation up to the expectations of their own wants, the following share some of the use of skills:
1, pay attention to the suction range and lift
Peristaltic pump suction range and head is an important factor affecting the flow, suction range is the horizontal position of the liquid surface to the vertical height of the pump head, and head is the pump head to the vertical height of the liquid outlet. If it is too long, it will make the flow rate of peristaltic pump decay rapidly.
2, liquid characteristics
The type and characteristics of the liquid peristaltic pump transmission also has an impact, especially viscous liquids and liquids containing particles, so in the formal production environment, you can be calibrated according to the instructions for flow.
3, flow size
Because of the operating principle of the peristaltic pump, so different flow rates will have an impact on the accuracy, such as small flow rate of the pump head and hose, the flow rate of the more accurate, but if you reach the pump head of YZ35 or even KZ50 and the hose with it, it certainly will not be too high accuracy, if the requirements for accuracy is very high, small flow rate of the pump head and hose is more recommended. and hoses are recommended.
4, maintenance
Daily use, pay attention to the loss of the hose, installation, pay attention to the hose placed in the correct position, which can greatly extend the service life of the hose, but also to ensure that the flow of peristaltic pumps to ensure that the transmission of more accurate.
Knowledge point two,Screw pumps are mainly used in what occasions
1, screw pumps because of its variable conveying, self-absorption ability, can be reversed, and can be transported solid particles of liquid, etc., in the wastewater treatment plant, the screw pumps widely used in the transfer of water, wet sludge and flocculant liquid.
2, screw pumps due to the structure and working characteristics, can transport high solid content of the media, flow uniformity, pressure stability, low speed is more obvious, due to good variable adjustability, and thus can be a pump for multiple purposes, transporting different viscosity of the media.
3, the installation position of the screw pump can be tilted arbitrarily, suitable for conveying sensitive goods and goods susceptible to damage by centrifugal force and so on.
Knowledge point three,Screw pump working characteristics
Screw pumps mainly have the following characteristics: simple structure, the use of safe and reliable, easy to use and maintain, the liquid continues to be an average, stable pressure, murmur and vibration of the small, with the ability of self-absorption, but the processing of the screw is more troublesome.
Knowledge point four,What is the three screw pump
Screw pumps are a rotary volumetric pumps, by the Screw how much, can be divided into single screw, twin screw, three screw and multi-screw pumps, three-screw pump, that is, there are three screw screw pumps, including one inserted in the pump cylinder in the active screw and its engagement with the two slave screw, three mutually meshing screw, in the pump cylinder according to each lead to form a sealing cavity, resulting in a seal between the suction and discharge ports.
Knowledge point five,peristaltic pump uses what
Peristaltic pumps of any of the use of the scene is to deal with fluid (can be any liquid with fluidity, can also be a mixture of solid-liquid), peristaltic pumps is the main role of the transfer. Peristaltic pump conveying accuracy can reach up to ± 0.5%, so it can meet the needs of quantitative conveying, but also can meet the needs of quantitative distribution.
From the level of product function, the use of peristaltic pumps is mainly: quantitative or metered delivery, quantitative or metered distribution. So where there is quantitative conveying and distribution needs of the application scenarios, can choose peristaltic pump to meet the application requirements.
Peristaltic pumps have excellent performance and reliability, so the application is very broad, to meet the application of various processes, including from experimental scientific research, analytical instruments to industrial production in many areas, so the peristaltic pump is very useful, the use of a very wide range of the following areas:
