Belt screw air compressor advantage

In the belt drive mode, the theoretical no-load pressure can be zero, and the rotor sucks in oil enough to lubricate the rotor and the bearing. Generally, for safety reasons, the pressure is maintained at about 0.5 bar.

The belt screw air compressor has the function of transmitting power and changing the speed. The belt screw air compressor relies on friction to transmit power, and it needs to consume a certain amount of energy, which accounts for 2% to 3% of the transmitted power. The belt must have a certain amount of tension to obtain sufficient friction. The belt tension subjects the bearings of the motor and the head to additional radial loads.

The belt screw air compressor compressor has higher requirements on the bearings of the motor and the head. Belt screw air compressor compressors have lower production costs and are generally only used for small compressors and economical compressors.

When the belt tension is insufficient, the belt will slip and the transmission power will be insufficient, which will not only cause the belt to wear at high temperature, but also reduce the speed of the air compressor and reduce the displacement. Always check the belt tension and pull the belt or replace the belt in time.

Belt screw air compressor features

  1. Our air compressor is compact in design and simple in appearance, which greatly reduces the space occupancy.
  2. Detachable bellows air outlet, which is more convenient and labor-saving, whether it is normal cleaning or regular maintenance.
  3. New high-quality sound insulation materials and advanced soundproof box design ensure that the working noise is within the ideal range, creating a quieter and more comfortable working environment for users.
  4. Advanced and efficient all-round intelligent control gas, while ensuring the performance of the equipment, also brings users a better operating experience.
  5. Our air compressor realizes stemless adjustment of high energy-saving exhaust volume. When the gas consumption is reduced, the exhaust volume of the machine will also decrease, the amount of the same gas will increase, and the displacement of the machine will increase accordingly. An optimal state of high energy efficiency.
  6. The air compressor has super-environmental adaptability. Our air compressor cooling system is quoted from the latest foreign design and is suitable for working in any environment. It also requires no special foundation for simple installation.
