Introduction

1. Size: 1800x1250x1680mm, weight: 1120KG

2. Application: Small industrial air compressor is based on the principle of permanent magnet frequency conversion, using the powerful magnetic field generated by the permanent magnet and the magnetic field generated by the electric current in the coil to interact and achieve efficient energy conversion. By adjusting the motor speed through the frequency conversion controller, the air output can be precisely controlled to meet the needs of different working conditions. With high efficiency, energy saving and stability, the permanent magnet frequency conversion screw blower is widely used in building construction, mining, industrial manufacturing and petrochemical industries.

Details

High efficiency and energy saving

The permanent magnetic frequency conversion technology of small industrial air compressor can precisely adjust the motor speed according to the actual air demand, so that the blower can maintain high efficiency under different working conditions, and save more than 20%-35% energy compared with the traditional Roots blower.

Stable pressure

The output air pressure fluctuation is small, which can provide stable air source support for various processes, which is conducive to the stable operation and prolonged service life of the equipment.

Low noise

The aerodynamic noise of the screw rotor is very small, together with the wave-shaped air inlet and outlet design, the airflow fluctuation can be reduced to a lower level, while some of the products are equipped with soundproof chassis, which further reduces the operating noise.

Reliable operation

Fewer parts, no wearing parts, reliable operation, and the use of high-strength alloy steel and special coating technology, so that the rotor gap is smaller, improving the volumetric efficiency, but also effectively protect the rotor, prolonging the service life.

Uses

Permanent magnet variable frequency screw blowers have a variety of uses in factories, including the following:

Pneumatic conveying

It can be used to convey powdery and granular materials in the factory, such as cement, coal powder, grain, etc., from one place to another through pipelines to achieve efficient and clean transmission of materials, avoiding the problems of dust pollution and high labour intensity that may be brought about by manual handling.

Workshop Ventilation

Provide ventilation for the workshop, send fresh air into the workshop, and at the same time discharge the dirty air, heat, moisture and harmful gases in the workshop, etc., to improve the air quality and working environment in the workshop, and safeguard the health and working efficiency of the employees.

Air supply for pneumatic equipment

Provide power air source for all kinds of pneumatic equipments in the factory, such as pneumatic tools, pneumatic valves, pneumatic fixtures, etc., to ensure the normal operation of these equipments, which has the advantages of stable air supply, adjustable pressure, etc., and can satisfy the working requirements of different pneumatic equipments.

FAQ

Q: What are the requirements for the installation environment of permanent magnet frequency conversion screw blower?

A: Generally, it is required to be installed in a dry and well-ventilated place, and enough space should be left around for easy maintenance and repair. The ground needs to be level to avoid vibration affecting the operation of the equipment, and at the same time, it should be far away from high temperature sources and corrosive gases.

Q: How to judge whether the equipment needs to add lubricant?

A: You can observe the oil level meter and check whether the oil level is in the middle position of the oil mark after shutdown, if it is lower than the middle position, it needs to be added.

Q: How often do I need to replace the air filter element?

A: Usually, the filter element must be replaced after one year of use. Normally, it should be checked regularly, if the filter is found to be clogged, which affects the air intake, it needs to be replaced in time even if it has not reached one year.

Q: What is the reason for the sudden increase in noise when the equipment is running?

A: It may be caused by bearing wear, gear damage, rotor imbalance, air intake filter clogging or muffler failure.
