Entering the TWH era.Power battery manufacturers are prone to increase production capacity by tens of thousands of GWH, and the scale of the unit production line of the new project is increased by 1-2 times, which means that the production efficiency requirements of lithium manufacture equipment is also significantly increased, forcing the upgrading of equipment technology.
Electrolyte injection As a core part of the lithium battery production process, directly affects the electrochemical performance, cycle life and safety of lithium batteries.
With the increase of battery capacity and production line capacity, new requirements such as High efficient, maintenance free and safer are put forward for the key equipment "injection pump" in the electrolyte injection link.
As a solution provider specializing in the precision fluid area such as filling, dispensing, spraying and pre-filling,(hereinafter referred to as Guangzhou Ascend) has been committed to the development of lithium battery injection pump technology since 2009, from the traditional electric ceramic pump, intelligent pump, to the constant flow metering pump, continue to lead the development of lithium battery injection pump technology route.
Focusing on the new demand of power battery scale manufacturing, Guangzhou Ascend launched FSH-CF constant flow metering pump, effectively meet the new requirements of lithium battery injection under mass production and manufacturing, and has been applied in more than 5000 units in China.
The general principle is that the FSH-CF constant flow metering pump breaks through the traditional method of liquid injection, and the motor drives the cam mechanism to drive the three ceramic pistons for reciprocating movement. The three ceramic pistons are arranged according to specific positions, so that when the motor turns through a certain angle, the dispensing volume of the pump remains the same, and can achieve the effect of no intermittent work. Therefore, the dispensing volume can be adjusted according to the control motor rotation angle.
It is also based on the above-mentioned special working principle that makes the product have the outstanding features of high efficiency, maintenance-free, no-pump jam, up to 0.1% accuracy, linearity without pulsation, and continuous metering to meet the new needs of power battery manufacturing.
Guangzhou Ascend already has launched FSH-CF30 and FSH-CF150 series products.FSH-CF30 series has an efficiency of up to 50ml/s; while FSH-CF150 series is the new higher flow rate constant flow metering pump with an efficiency of up to 150ml/s, which is suitable for the production workshop of aluminum case battery with higher efficiency requirements for liquid injection.
With the increase of battery capacity and production efficiency, customers have an urgent need for the improvement of injection efficiency.
The FSH-CF30 constant flow metering pump can reach up to 50ml/s, and the FSH-CF150 high flow pump can reach 150ml/s. Its liquid injection efficiency is higher, reaching 2-10 times of the traditional injection pump, which can meet the customers' requirements for capacity improvement.
For battery companies, Many production line has been directly through the replacement of the Ascend constant metering pump to enhance the capacity of the existing production line; new production line can use Ascend constant metering pump to directly enhance the capacity and efficiency, or reduce the number of pumps to save costs.
FSH-CF constant flow metering pump adopts a new type of fully enclosed chamber to avoid the crystallization caused by the contact between electrolyte and air, which fundamentally solves the trouble of pump jamming. The electrolyte is highly corrosive, and no pump jam /maintenance-free design of FSH-CF constant flow metering pump greatly reduces the probability of operators contacting the electrolyte. Operator don't need to spend much time in repairing the injection pump. Even if operators are on vacation for a long time, They don't need to worry about the pump jam when start the pump again.
The FSH-CF constant flow metering pump communicates with the filling by Ethernet, and the parameters can be modified remotely through the network.
No pump jam, maintenance-free design freeing operators from the injection workshop, which can reduce the number of operators in the injection workshop and provide a more comfortable working environment for operators to operate remotely, ultimately achieving continuous and stable safe production.
It is not limited by the injection volume, and can continuously measure injection volume, compatible with small, medium, large and super large power battery electrolyte injection. It is a must-have liquid injection pump for soft pack power and aluminum case power battery manufacture, and it is easier and faster to change the product model and modify the liquid injection parameters directly digitally.
Guangzhou Ascend adopts precision servo drive to digitally set/modify the liquid injection parameter and can achieve intelligent closed-loop control, thus significantly improving the CPK value, enhancing the consistency and stability of lithium battery liquid injection and higher yield rate.
According to the official introduction of Guangzhou Ascend, its FSH-CF constant flow metering pump has been used in more than 5000 units of domestic lithium battery company, while in the production line has been batch and long time verification and recognition, the product is efficient and reliable.
Up to now, Guangzhou Ascend lithium products have served most of the top 30 customers of China lithium battery company, and exported to Japan, South Korea, the United States, the United Kingdom, Germany and other overseas markets.
With the core concept of "professionalism, concentration, innovation and efficiency", Guangzhou Ascend always insists that technology never ends and will continue to invest in R&D technology to continue to lead the technology and development line of injection pumps and grow together with customers.
