Smoke Exhausters
All smoke exhausters that PJSC “Dalenergomash” manufactures are stationary, with installation on a foundation. Electric motorsare used to drive the exhausters. Depending ontheir structural configuration, the smoke exhausters can be divided into two types: with ashaft-supporting part, and without it.
Smoke exhausters (Д-3,5 and ДН-12,5У) without a shaft-supporting part have a one-piece design. The scroll and the driving motor are mounted on a common frame to form an integrated unit. The impeller is forced directly onto the shaft of electric motor.
Smoke exhausters with a shaft-supporting part have two separate sub-units: a shaft-supporting part with an impeller forced onto its shaft, and a scroll. During installationthe shaft-supporting part and the scroll are arranged on a foundation and fixed to it by means of anchor bolts.
The electric motor is also installed on the foundation; it is joined to the shaft with the aid of a coupling supplied togetherwith the smoke exhauster. For smoke exhausters with a shaft-supporting part a customer on its own buys electric motors. On customer’s request, an electric motor can be included into a scope of supply. Except forД-3,5-type, all other smoke exhausters have inlet guide vanes.
Smoke exhausters of ДН and Дtype are made with a right or with a left rotation of impeller. The right rotation is clockwise, and the left rotation is counterclockwise when the impeller is viewed from the side of electric motor. Rotation direction should be specified by ordering of a smoke exhauster.
Orientation of the delivery connecting pipe in standard makes of smoke exhausters is as follows:
- smoke exhauster Д-3,5 – 270°;
- smoke exhauster ДН-6,3 – 0°;
- all other smoke exhausters– 90°.
On request, orientation of the delivery connecting pipe can differfrom the standard one, the incremental step is 15°. Rearrangement of the scroll for another orientation angle can be done on-site with observance of technical documentation requirements.
