In the maintenance of electric hoist, one of the most important is to fill lubricating oil regularly. What effect can reasonable filling lubricating oil have?
In electric hoist maintenance section, a crucial is filling lubricating oil regularly, then the reasonable filling lubricating oil can have what effect?
There are three types of lubricants, liquid, semi-fixed and fixed, which are usually lubricating oil, grease and fixed lubricant respectively. Lubricating oil and grease are mainly used.
The main functions of lubricating oils are wear reduction, cooling and corrosion protection.
There are three types of lubricants, liquid, semi-fixed and fixed, which are usually lubricating oil, grease and fixed lubricant respectively. Lubricating oil and grease are mainly used.
The main functions of the lubricating oil is to reduce wear and tear, cooling and corrosion.
The selection principle is as follows:
1. In order to reduce the loss of energy, the lubricating oil with small viscosity is preferred to be selected under the condition of ensuring the safe work of machine wear parts.
2. For the friction parts with high speed and light fit work, choose the lubricating oil with small viscosity. For the parts with low speed and heavy load work, choose the lubricant with large viscosity.
3, about winter working machines should choose small viscosity, low solidifying point of lubricating oil; About summer job rotation parts choose the viscosity of lubricating oil.
4, impact fit and reciprocating running friction appearance, should choose the viscosity of lubricant.
5, the working temperature is higher, the wear is more severe and the processing is rough friction surface, should choose large viscosity lubricant.
6, the machine working at high temperature should choose lightning high lubricants.
7, when there is no suitable for lubricating oil, should be chosen near the generation of oil or mixed oil viscosity (configuration).
Lubricating grease is mainly composed of mineral oil and thickener, and the commonly used thickener is calcium soap and sodium soap. The effect is anti-corrosion, wear and sealing.
The advantage of grease is that the coefficient of dynamic friction is small, and it does not leak when the machine is working or stopping. The disadvantage is that the coefficient of static friction is large, which will increase the difficulty of starting the machine.
In the filling of electric hoist parts, some customers will choose lubricating oil, and some will choose lubricating grease, and the filling of different bearing parts may also be different.
