持续横倾：15°
持续纵倾：10°
振动：有
冲击：有
特点
JCL(CLQ)型：
尺寸小、重量轻
低噪音、低振动
防腐性好
气密性好
启动力矩小
抗摇摆、振动和冲击性强
结构型式
JCL(CLQ)型：
通风机为卧式、单级、单吸式结构，亦可制成立式结构。
通风机与电动机的联接形式为直联式，即叶轮直接装在电动机轴上。
叶轮由铝合金材料铆接制成，并经静、动平衡校正。
机壳、进风口等采用普通钢质材料焊接而成，并制成气密式结构。
通风机可制成逆转(左转)或顺转(右转)：
逆转(左转)——从电动机端正视，叶转按逆时针方向旋转，以“L”表示。
顺转(右转)——从电动机端正视，叶轮按顺时针方向旋转，以“R”表示。
通风机的出风口位置按叶轮转向制成以下几种基本型式。根据需要，出风口位置允许按30°或22.5°变化的其它型式。
PREFACE
JCL(CLQ)series centrifugal fans for marine or navyuse 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
JCL and 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.
JCL and 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.
CHARACTERISTICS
JCL(CLQ) type:
small in size,light in weight
low noise and low vibration
good anticorrosiveness
good airtightness
small starting torque
strong resistance against swing,vibration and impact
STRUCTURE TYPE
JCL(CLQ) type:
The ventilator is of horizontal,single-stage and single-drawing type with direct conneciton for the motor.It can also be constructed into a vertical type with the vane wheel on the motor shaft.The vane wheel is made of rivetted aluminium alloy.They have calibrated under both static and dynamic balance.Both the machine casing and the inlet are made of welded common steel with airtight structure.The ventilator can be made for counterclockwise(left)or clockwise(right)rotation,conterclockwise(left)rotation:viewed from the motor side.The vane wheel rotates anti-clockwise and indicated as“L”.Clockwise(right)rotation:viewed from the motor side,the vane wheel rotates clockwise and indicated as “R”.The outlet position of ventilator,according to the rotating direction of vane wheel,is made into the following main types,In conformity with the requirement,the outlet position is allowed to use other types.the angle of which is 30° or 22.5°.
