This will depend on how high the tariff is and what it does to the relative price of the imports and competing products that are produced domestically.
If the tariff is relatively low, revenue will go up. Imports will still out-compete domestic goods and will therefore keep coming in. If the number of imports does not go down much, the tariff will bring in money.
But if the tariff is very high, it may not help government revenues. If the tariff is high enough, imports may simply stop coming in. Instead of buying imports, people will buy domestically produced goods. In such a case, the tariff will not bring in any revenue.
