  What determines the efficiency of a building hoist

  The reducer of building hoist should be lubricated by lubricating oil as far as possible, and lubrication can be used when oil lubrication is inconvenient. The following aspects should be considered when choosing specific lubricant grades.

  1. Working temperature: When working at low temperature, it should choose lubricating oil with small viscosity and low condensate point; When working at high temperature, it should choose lubricating oil with large viscosity, high flash point and good oxidation resistance; when the working temperature changes greatly, it is advisable to choose the lubricating oil with good viscosity temperature characteristic and high viscosity index.

  2, the speed of movement: low speed is not easy to form a dynamic pressure oil film, it is advisable to choose a high viscosity lubricant or needle into the small lubrication refers to the high speed, in order to reduce power loss, it is advisable to choose a low viscosity lubricant or needle into the large grease.

  3, Transmission type: Different types of deceleration device on the lubricant to Shenzhen city in many aspects is different should be as far as possible targeted to select the exercise of the form of lubricants.

  4, working load: the higher the viscosity of lubricating oil, the greater the bearing capacity of the film, so when the work load, should choose the viscosity of high and oily and very good pressure lubricants. In the work, the impact load is suitable for lubricating oil with large viscosity or small needle penetration.

  5, the work surface status: The work surface roughness is big, the request uses the viscosity big lubricant or the needle enters the small lubricating oil refers, with the surface clearance small, the request uses the viscosity small lubricant.
