JCZ(CZ)型：
通风机制成电动机置于机壳内的结构，叶轮直接装在电动机轴上。
叶轮由防腐铝合金浇铸制成，叶轮前面装有导流罩。机壳采用普通钢质材料焊接而成。
通风机制成从电动机端正视，叶轮按顺时针方向旋转。在使用中，允许通风机逆向旋转。
通风机可立式或卧式安装在管道内，也可安装在甲板上。可用于抽风或送风。
按用户需要，JCZ(CZ)型通风机可配套提供风帽。

PREFACE
and JCZ(CZ)series axial-flowfans for marine or navyuse series fans are designed and manufacwtured according to the standards of the state for GB11865《Marine Centrifugal Ventilator》,GB11864《Marine Expeosion-proof Axial Flow Fans》 《Rules and Regulations for the Construction and Classifi-cation of Sea-going Steel Ships》and《Rules and Regula-tions for the Construction of PLA Naval Ships》.
This series of ventilators have been examined and provecd up to stand by the Register of Shipping of china and have got the certificate.They are also approved by the authority of shipping equipment and research Staff.
USES
JCZ ventilators can carry ordinary air,seaair containing salt fog and air containing oil fog and other corrosives.
These ventilators are suitable for ventilation of all kinds of tanks in the naval and merchant ships.They can also be used for partly cooling.They can be used on land,either.
JCZ ventilators can be matched with Y-J three phase naval induction motor or Y-H three phase marine induction motor(50Hz,380V or 60Hz,440V)
WORKING CONDITIONS
ambient temperature:-25～55℃
relative humidity of air:≤95%
cyclical oscillation: 22.5～45° (oscillation cycle 5～10s)
sustained horisontal tilting:15°
sustained vertical tilting:10°
vibration:existent
shock:existent.
JCZ type:
The ventilator is manufactured with a built-in casing motor structure.The vane wheel is directly mounted on the motor shaft.The vanewsheel is made of anticorrosive cast aluminium alloy while the casing is made of welded common steel.In front of the vane wheel there is an inducer.Viewed from the motor side,the vane wheel rotates clockwise while in service the ventilator is allowed to rotate reversely.The ventilator can be installed vertically or horizontally and can also be installed on the deck or in the pipe.It may be used for pumping or inducing air.According to the user's need,we can supply hood together with JCZ type ventilator.
MODELS
The models of ventilators are expressed by the first letter of the Chinese phonetic name,the outer diameter of the vane wheel,the power and the rotational speed of the motor,etc.
For example:
(JCL-30/1.5-1460) R180°(JCZ-90A/7.5—1460)
Where：
J-for naval ship use
C-for merchant ship use
L-centrifugal ventilator
Z-axialflow ventilator
30-the outer diameter of the vane wheel,30cm
90-the outer diameter of the vane wheel,90cm(circle integer)
A-code for vane wheel
15-the power of motor,1.5kw
75-the power of motor,7.5kw
1460-the standard rotational speed,1460r/min(50Hz)
R180°-clockwise(right)rotation,the position of the wind opening-180°
