Is it considered usury for the bank to purchase the necessary equipment for my project, and then I repay the amount to them with a small interest, instead of them giving me money?

If the transaction with the bank is conducted according to the Shariah-compliant regulations of Murabaha, with the bank owning the goods and equipment before selling them, and without stipulating a penalty for late payment, then there is no objection. However, if the bank does not own the equipment and merely pays its price, then recovers it with interest, this is a forbidden usurious loan.
