Abstract
The utility model discloses a shield pump built-out cooling device comprising a shield pump, a cooling water jacket disposed in the shield pump, and a heat pipe connected with the shield pump. A built-out cooling device is disposed on the heat pipe near the inlet of the shield pump, and the built-out cooling device is mainly constituted by a cooling chamber, a cooling pipe disposed in the cooling chamber, on which are respectively arranged a cold water inlet and outlet. Two ends of the cooling pipe are respectively connected with the heat pipe, and the cooling pipe is disposed in the cooling chamber in the shape of spiral. In the utility model, the cooling-heat exchanging area of the heating medium can be increased to accelerate the cooling speed of the heating medium, thereby the good cooling effect can be achieved. Compared with the prior shield pump, which cools the water through the cooling water jacket, the temperature of the heating medium can be lowered by more than about 20 DEG C in practice, thereby the ideal cooling effect of the heating medium can be achieved, the temperature of coils can be guaranteed to prevent the shield pump from jump stopping or prevent the coil from being burned. The utility model has advantages of small size, simple production, and convenient assembly as well as disassembly.
Description
Technical field
The utility model relates to a kind of chemical industry cooling unit of production of polyester, especially a kind of external cooling unit of canned motorpump that is used for.
