Hoist motor maintenance
 

The motor is an important part of the winch, winch is also the most expensive parts, if damaged, repair or replacement costs that would be too high. So here we remind customers to take good care of the windlass or winch motor. Maintenance methods are as follows:

1、使用环境应经常保持干燥,电动机表面应保持清洁,进风口不应受尘土、纤维等阻碍。

1, the use of the environment should be kept dry, motor surface should be kept clean, Menorca should not receive dust, fiber and other obstacles.

2、当电动机的热保护连续发生动作时,应查明故障来自电动机还是超负荷或保护装置整定值太低,消除故障后,方可投入运行。

2, when the motor thermal protection continuously happen when, should find fault from motor or overload or protection device setting value is too low, eliminate malfunction, can be put into operation.

3、应保证电动机在运行过程中良好的润滑。一般的电动机运行5000小时左右,即应补充或更换润滑脂,运行中发现轴承过热或润滑变质时,液压及时换润滑脂。更换润滑脂时,应清除旧的润滑油,并有汽油洗净轴承及轴承盖的油槽,然后将ZL-3锂基脂填充轴承内外圈之间的空腔的1/2(对2极)及2/3(对4、6、8极)。

3, should ensure good lubricating motor during operation. General motors run for about 5000 hours, should complement or replace grease, bearing overheating or lubrication modification found in operation, the hydraulic timely for lubricating grease. Replacing the grease, should remove old lubricating oil, and the oil tank of gasoline to clean the bearing and bearing cover, then the ZL-3 grease filling the cavity between the inner and outer ring of the bearing 1/2 (2 pole) and 2/3 (4, 6, 8).

4、当轴承的寿命终了时,电动机运行的振动及噪声将明显增大,检查轴承的径向游隙达到下列值时,即应更换轴承。

4, when the bearing life end, motor running vibration and noise will increase obviously, check the radial clearance of the bearings to the following values, i.e.replace bearings.

5、拆卸电动机时,从轴伸端或非伸端取出转子都可以。如果没有必要卸下风扇,还是从非轴伸端取出转子较为便利,从定子中抽出转子时,应防止损坏定子绕组或绝缘。

5, removing the motor, from the shaft extension end or end of rotor can be taken out. If it is not necessary to remove the fan, or from a shaft extension end out rotor is more convenient, from out of the rotor in the stator, stator winding insulation should prevent damage or.

6、更换绕组时必须记下原绕组的形式,尺寸及匝数,线规等,当失落了这些数据时,应向制造厂索取,随意更改原设计绕组,常常使电动机某项或几项性能恶化,甚至于无法使用。

6, the replacement of winding must take note of the primary winding form, size and number of turns, wire, when the loss of the data, should ask factory, arbitrarily change the original design of the motor winding, often one or several performance deterioration, and even can not be used.
