Ceramic metering pump as precision fluid metering, liquid injection, adding, packing, dropping, sampling of the ideal metering equipment, ceramic metering pump has been widely used in battery injection, biological agents, micro electronics, food and beverage and chemical industry and other fields. In the production process of high standard, high requirements in the process of high precision, corrosive, toxic fluid medium metering addition and transportation tasks. After years of practical application and technical improvement, now ceramic metering pump has entered its high-speed growth period.
Now, due to the new material ceramic technology from raw material - sintering - precision processing is stable and mature. The performance, quality and cost of the ceramic metering pump have been greatly changed, and the precision and stability of the ceramic metering pump can almost complete the chemical protection requirements of conveying most liquid media under the dynamic drive. With the general improvement of Chinese industrial intelligent automation production requirements, as a domestic ceramic metering pump r & D and sales enterprises, with skilled, experienced r & D personnel. The safety, controllability and intelligence of ceramic metering pump become more and more important.
The principle of
Ceramic metering pump is mainly driven by stepping motor, ceramic valve body, adjustment controller three important institutions. Because of the power drive mode is different, there are two leading rotary reciprocating and linear push-pull type.
Rotary reciprocating by the stepping motor power drive device drives the reciprocating push and pull of the ceramic rod rotation (ceramic piston) to achieve the reciprocating piston movement, the fluid is transported to the desired destination. Precision ceramic valve cavity to ensure each suction and discharge, and then realize the delivery of the medium precision measurement.
The linear push-pull type is telescopic movement by the stepping motor. Under the cooperation of the one-way valve, it can pull in and push the fluid to achieve the purpose of precise measurement.
Rotary reciprocating ceramic metering pump
Rotary reciprocating ceramic metering pump is widely used in the field of battery injection and biological reagents because of its simple structure and very convenient maintenance and repair, and it only takes 2-3 minutes to disassemble and assemble. There are many limitations for high viscosity medium in high pressure working environment.
Linear push-pull ceramic metering pump
The linear push-pull ceramic metering pump has a high degree of intelligence, and there is no need to manually adjust the amount of liquid injection, so as to achieve intelligence and automation. Compared with the rotary reciprocating structure is relatively complex disassembly trouble, more pump body components.
control
The metering pump controller is equipped with R232 communication port of upper computer, which can realize the monitoring and control of metering pump by upper computer. With the switch quantity input and output, alarm, always feedback, complete feedback signal, etc.
Rotary reciprocating control
Each stroke cavity of metering pump determines its metering capacity. The flow rate of the pump output medium depends on the length of the stroke, the volume of the ceramic cavity and the number of strokes. Under the condition of determining the metering medium and working pressure, the output of the metering pump can be adjusted by manually adjusting the stroke length (i.e., the Angle) through the man-machine interface to set the stepping speed and rotation direction.
Straight push and pull control
Similarly, each stroke cavity of the linear push-pull ceramic metering pump determines its metering capacity. The flow rate of the pump output medium depends on the length of the stroke, the volume of the ceramic cavity and the number of strokes. Under the condition of determining the metering medium and working pressure, the output of metering pump can be adjusted by adjusting the stroke length. Although both stroke length and stroke compensation can be used as adjustment variables, in engineering applications, stroke length is generally regarded as coarse adjustment variable and stroke compensation as fine adjustment variable: adjust the stroke length to a certain value, and then change its compensation to achieve fine adjustment and increase the flexibility of adjustment. In relatively simple applications, the stroke length can also be set manually, using only the stroke frequency as the adjustable variable, thus simplifying system configuration.
