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
