Brief introduction of Wannan motor Limited by Share Ltd explosion-proof motor characteristics

The explosion-proof motor is separated from the explosive gas mixture by the electrical part of the explosion proof enclosure which may produce sparks, electric arc and dangerous temperature. However, this case is not sealed, the explosive gas mixture can be through the shell of the various parts of the joint surface gap into the motor. When the ignition source of exposure and the shell of spark and arc, high risk and so on may occur explosion, then vibration motor burst housing will not only damage or deformation and explosion flame or hot gas through a bonding surface gap came, also cannot ignite explosive gas mixture around.

Main features are:

(1)全系列采用F级绝缘，温升按B级考核；

(1) the full range of F insulation, temperature rise by B level assessment;

(2)功率等级、安装尺寸及转速的对应关系与DIN42673一致，同时考虑到与YB系列 的继承性和Y2系列的互换性，作了必要调整，更加有效和适用；

(2) power rating, installation size and speed corresponding relationship with the din42673 consistent, taking into account and Yb series of inheritance and Y2 series of interchangeability and made the necessary adjustment, more effective and applicable.

(3)外壳防护等级提高到IP55；

(3) enclosure protection level is raised to IP55;

(4)噪声限值比YB系列低，接近YB系列的I级噪声，振动限值与YB系列相当；

(4) the noise limit is lower than the YB series, close to the YB series I noise, and the vibration limits are comparable to the YB series;

(5) 全系列选用低噪声深沟球轴承，机座中心高在180mm以上电机设注排油装置；

(5) full range of selection of low noise deep groove ball bearings, shaft center height above 180mm motor with injection oil discharge device;

(6)主要性能指标达到20世纪90年代初国际先进水平；

(6) the main performance indicators reached the international advanced level in the early 90's of the's.;

(7)电机散热片有平行水平分布和辐射分布两种，以平行水平分布为主。

(7) there are two kinds of parallel horizontal distribution and radiation distribution of the motor heat sink.
