Solutions to improve efficiency and save energy for fabric tensioners

Using INVT’s PLC and multi-function inverter for the control solution of the needle tensioner system to help the machine system operate stably, improve the engine’s durability and save up to 10% of electricity consumption for the business owner. Karma.

The needle tensioner is a terminal device in a textile dyeing factory, which has the function of helping to stretch the fabric to the correct size, treat the shrinkage, create surface aesthetics and can adjust the weight of the finished fabric within certain. Mostly, the needle tensioner system is controlled by a dedicated controller according to the machine, the fan motor starts directly from the grid and always runs at a fixed speed at maximum capacity.

CUSTOMERS’ DIFFICULTIES

Difficult operating system
When there is a problem, it usually takes a long time to repair and there is no stock to replace
Some machines are imported from Japanese yards, using 3P 220V power inverters that are not suitable for the power grid in Vietnam.
The motor operates at full capacity continuously, consuming a lot of power

SOLUTION ANALYSIS
