Description
Technical field
The utility model relates to and a kind ofly is applicable to textile manufacturing machine such as tight frame suction negative pressure and gets rid of the back to high pressure centrifugal ventilator of trifle in the world, also can be used for high pressure suction, the exhaust occasion of other no etchant gas.Belong to technical field of textile machine.
Background technique
Be used for textile manufacturing machine suction negative pressure and the ventilator of getting rid of trifle in the world such as tight frame at present, be mainly the high pressure centrifugal ventilator of forward direction impeller (being that impeller blade is a forward-type).This is because the ventilator that adopts the forward direction impeller under identical impeller diameter, can obtain high relatively pressure.And tight frame has the restriction of comparison strictness to the volume of supporting blower fan.But the forward direction blower fan also exists, and fan efficiency is low, noise is high, the working zone is narrow, impeller channel complex structure, manufacturing cost height, easily surge and easy shortcoming such as overload.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of and satisfying textile manufacturing machine such as tight frame suction negative pressure and getting rid of under the prerequisite of the needed blower sizes of trifle in the world, aeroperformance, what have high efficiency, low noise, low cost, simple in structure, function admirable is used for the back to high pressure centrifugal ventilator of tight frame.
The purpose of this utility model is achieved in that a kind of back to high pressure centrifugal ventilator, comprises impeller, and described impeller comprises blade, and the blade profile of described blade is that the backward type circular arc is plate shaped.
To high pressure centrifugal ventilator, described blade radius of arc is 1.15～1.25 with the ratio of impeller diameter behind the utility model; The impeller outlet angle is 60 °～65 °; The impeller inlet width is 0.18～0.24 with the ratio of impeller diameter; Impeller outlet width is 0.09～0.12 with the ratio of impeller diameter; The impeller inlet diameter is 0.3～0.35 with the diameter ratio of impeller; The impeller blade number is 10～14.
Back of the present utility model to high pressure centrifugal ventilator with form by impeller outlet angle with large inclined angle and backward type circular arc plate blade back be main feature to the high pressure type impeller, can make back of the present utility model satisfy textile manufacturing machine suction negative pressure such as tight frame to high pressure centrifugal ventilator and get rid of under the prerequisite of the needed blower sizes of trifle in the world, aeroperformance, have blast height, efficient height, noise is low, the working zone is broad, simple in structure, advantage such as manufacturing cost is low, for textile manufacturing machines such as tight frame suction negative pressure with get rid of trifle in the world and have good result.
