英语翻译
一、产品型号差异比较：
1.FSDB-30型、FSDB-90型与ZSDB-90型液压盘式制动器的主要差别在于制动形式；FSDB-30型、FSDB-90型为常闭式制动器,即采用弹簧制动,液压动力开闸；而ZSDB-90型为常开式制动器,即采用液压动力来制动; 液压动力消失,制动器开闸.
2.FSDB-30型与FSDB-90型液压盘式制动器的主要差别在于制动力和安装尺寸的区
别；制动力及其参数见产品简述,安装尺寸的区别见附图.
二、产品使用说明：
FSDB、ZSDB系列液压盘制动器主要适用于并网型风力发电机组中用于机械驱动配套的机械制动.它具有体积小、结构紧凑、制动力矩大、制动时间短、制动性能稳定、摩擦衬垫耐高温、安装调整方便等特点.此外它还适用于起重运输、冶金、港口装卸、吊索设备等多种行业的与机械驱动配套的机械制动和减速.
三、使用条件
采用液压动力单元提供相应的额定压力工作,使制动器开闸(常闭式)；或制动(常开式) .
四、环境条件
1.使用地点海拔不超过2000m;
2.环境空气温度为-40℃—80℃; 超出此范围时由供需双方协商确定.
3.环境空气的年平均相对湿度小于或等于95%;
4.环境中不应有易燃、易爆性气体和介质;
5.安装后的制动盘的端面跳动应符合GB7019的要求.

1,Model Comparison:
1.FSDB-30,type-90 and FSDB ZSDB-90 hydraulic disc brake brake the main difference lies in the form of FSDB-30,FSDB-90 closed for regular brake that the introduction of spring brake,Hydraulic Power gate opening,and ZSDB-90 for the open-type brake,a hydraulic power to brake; Hydraulic Power disappeared,brake gate opening.
2.FSDB-30 and FSDB-90 hydraulic disc brake system is the main differences between driving force and the district to install size
While another dynamic system parameters and see brief product,the installation of the size distinction see attached map.
Second,product use:
FSDB,ZSDB series of hydraulic disc brake applies to the main grid and turbine-driven machinery for the group supporting the mechanical brake.It is small,compact structure,the brake torque,braking short time,braking performance and stability,high temperature friction pad installed adjustment convenient features.It also applies to lifting transport,metallurgy,port handling,equipment,and other slings and mechanical drive industry supporting mechanical braking and deceleration.
Third,conditions of use
A hydraulic power unit provides the corresponding nominal pressure,the brake gate opening (regular closed); or braking (open-type).
4,environmental conditions
1.Use sites not more than 2000 m above sea level;
2.Ambient air temperature of -40 ℃ -80 ℃; beyond the scope determined by the supply and demand consultation between the two sides.
3.Annual average ambient air relative humidity is less than or equal to 95%;
4.Environment should not be flammable,explosive gas and media;
5.Installed after the end of the brake disc beating should be consistent with the requirements of GB7019.
