The characteristics of the mobile screw machine are as follows:
1. It is convenient to move frequently, the working conditions are varied, and the load changes greatly;
2. Mobile screw machineMore heavy-duty, medium-speed or low-speed transmissions, most require frequent starting, and often withstand impact loads;
3, the field environment is harsh, humid, with rock dust, coal dust and gas, and some contain Sulfur harmful gas, so many mobile screw machines will encounter fire, explosion, corrosion and other problems;
4, open-air moving screw machine to withstand wind, sun, rain and hot summer cold, etc. Climate change;
5, due to the small space, the maintenance of the machine is more difficult, so the mobile screw machine is required to be durable and easy to repair.
Mobile screw machine Suggestions for lubricating oil:
1. The volume of the mobile screw machine and the volume of the fuel tank are small, and the amount of lubricating oil installed is also small. The oil temperature is higher during work, which requires the lubricant to have better thermal stability and oxidation resistance.
2, because the environment in the wild is bad, coal dust, rock dust, water, the lubricating oil is inevitably contaminated by these impurities, so the lubricating oil should have better anti-rust, anti-corrosion and anti-emulsification properties; When the lubricant is required to be contaminated, its performance will not change too much, that is, it is less sensitive to pollution.
3, the open-air machinery winter and summer temperature changes greatly, and some areas have large temperature difference between day and night, so the viscosity of the lubricant is required to change with temperature, it is necessary to avoid the oil viscosity becomes too low when the temperature is high. Therefore, the lubricating film cannot be formed, the lubrication effect should not be achieved, and the viscosity is too high when the temperature is low, so that starting and running are difficult.
4. For some mobile screw machines, especially those used in environments prone to fires and explosions, which require the use of lubricants with good flame resistance, flammable mineral oil cannot be used.
5, the lubricant is required to adapt to the seal, so as to avoid damage to the seal
