Comparison between pneumatic injection pump and Ji kerr ceramic injection pump
Date：2018-11-21 browse：339
Comparison between pneumatic injection pump and Ji kerr ceramic injection pump | ||
pneumatic | power-driven | |
Control mode | Additional controller systems are required | The system interface is rich, flexible, can be used directly on the workbench surface, can also be used for system integration and R232,R485 communication, with time feedback, complete feedback, alarm feedback, etc |
Sealing element | Contains dynamic seals, because the dynamic seals are not resistant to wear, need to be periodically removed and replaced | No dynamic seals, zero maintenance costs. |
Low injection accuracy | The injection accuracy is not high, easy to hang liquid, drip phenomenon, has an impact on the consistency of the battery quality, and waste electrolyte | High injection precision without hanging liquid, dripping phenomenon |
Pump valve body cavity | The pump valve chamber adopts the principle of pneumatic linear push and pull motion, and the suction and discharge are controlled by the one-way valve. The dead Angle in the chamber affects the accuracy | The pump valve chamber adopts the principle of rotary valve push-pull movement, and there is no dead Angle between suction and discharge to ensure accuracy. |
Pump valve piston | Composed of rubber parts easy to wear | Ceramic plungers wear well |
Transmission mode | The suction and discharge pressure of cylinder drive will be affected by the unstable factor of air source | Stepper motor drive suction and discharge pressure constant |
Production efficiency | The speed depends on the pressure | Closed-loop step, theoretically 1200 RPM, high repetition rate |
Easy maintenance | It takes 30-60 minutes | 5 minutes |
Service life | 2-3 years | Five to eight years |
Maintenance cost | Maintenance costs are mainly on the seal is easy to break, easy to crystallize | No dynamic sealing, easy to clean, no cost of wearing parts |
