Abstract
The utility model discloses a kind of split type spiral case, including spiral case upper casing, spiral case lower casing and alignment pin, the spiral case upper casing is fixedly connected with spiral case lower casing, and alignment pin is plugged between spiral case upper casing and spiral case lower casing；The spiral case upper casing is provided with sluice way, after the spiral case upper casing is fixedly connected with spiral case lower casing, drainage lumens is formed between the sluice way and spiral case lower casing of spiral case upper casing；The spiral case upper casing is provided with flow inlet with the junction of spiral case lower casing；The upper and lower surface of the sluice way is shaped by milling.The utility model uses the sluice way of split-type structural, spiral case to be shaped by milling, and water passage surface is smooth, reduces flow losses, improves efficiency；Save casting spiral case inner flow passage die cost, reduce single-piece manufacturing cost.
Description
Technical field：
The utility model is related to a kind of split type spiral case.
Background technology：
Existing spiral case is cast using monoblock type, casts spiral case inner flow passage rough surface, increases gas flow loss, and
Casting spiral case inner flow passage die cost is high, increases cost per unit.
Therefore, it is necessory to be improved to solve the deficiency of prior art to prior art.
Utility model content：
The utility model is to provide a kind of split type spiral case to solve the problems, such as above-mentioned prior art.
The technical scheme that the utility model is used has：A kind of split type spiral case, including spiral case upper casing, spiral case lower casing and fixed
Position pin, the spiral case upper casing is fixedly connected with spiral case lower casing, and alignment pin is plugged between spiral case upper casing and spiral case lower casing；
The spiral case upper casing is provided with sluice way, after the spiral case upper casing is fixedly connected with spiral case lower casing, spiral case upper casing
Drainage lumens are formed between sluice way and spiral case lower casing；
The spiral case upper casing is provided with flow inlet with the junction of spiral case lower casing；
The upper and lower surface of the sluice way is shaped by milling.
Further, the spiral case upper casing passes through screw or is welded and fixed to be connected with spiral case lower casing.
The utility model has the advantages that：The utility model uses the sluice way of split-type structural, spiral case to pass through
Milling shapes, and water passage surface is smooth, reduces flow losses, improves efficiency；Save casting spiral case inner flow passage die cost, reduce
Single-piece manufacturing cost.
