When installing the aluminum alloy tuyere, check the case first, and check whether there are other sundries in the case. In order to prevent rust, a little grease or mechanical oil should be applied to a part of the connecting surface. The joint surface of the tuyere fan and the foundation should be naturally compliant when connecting the inlet and outlet ducts, and should not be forced to connect. Do not add the duct gross weight to the prefabricated components of the fan, and pay attention to ensuring the position of the fan.
After the aluminum alloy tuyere is set, test whether the transmission group is normal, and make sure that it will not cause problems such as over-tightening and fixed partial bumps. If you find that it is not right, adjust it to the normal state immediately.
