Marine axial fan

PREFACEJCZ(CZ)series axial-flowfans for marine or navy use 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.USESJCZ 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) and others.WORKING CONDITIONSambient temperature:-25～55°relative humidity of air:≤95%cyclical oscillation: 22.5～45° (oscillation cycle 5～10s)sustained horisontal tilting:15sustained vertical tilting:10vibration:existentshock: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.MODELSThe 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 useC-for merchant ship useL-centrifugal ventilatorZ-axialflow ventilator30-the outer diameter of the vane wheel,30cm90-the outer diameter of the vane wheel,90cm(circle integer)A-code for vane wheel15-the power of motor,1.5kw75-the power of motor,7.5kw1460-the standard rotational speed,1460r/min(50Hz)R180°-clockwise(right)rotation,the position of the wind opening-180.Introduction companyQingdao Yongjian Marine Machinery Manufacture Co., Ltd.
