What are the differences between oil-free air compressor and oil compressor?

At present, oil-free air compressor is improved and developed on the basis of oil compressor. It mainly adopts two ways: one is to replace oil with water, and the other is to coat the rotor with self-lubricating coating. Because the bearings at both ends of the rotor at high speed need oil lubrication, it is necessary to make the lubrication space of the rotor bearing and the compression space of the rotor mutually

Classification of solenoid valves

Introduction to direct acting solenoid valve: There are two types: normally closed type and normally open type. When the normally closed type is powered off, it is closed. When the coil is powered on, electromagnetic force is generated to enable the moving iron core to overcome the spring force and pull in with the static iron core to open the valve directly, and the medium is in a path; When the coil is powered off, the electromagnetic force disappears, and the moving iron core resets under the action of the spring force

How to select post-processing equipment of air compressor

In a complete pneumatic system, in addition to using air compressors to produce compressed air, post-treatment equipment is also needed to cool, dry and purify compressed air. The post-treatment equipment of air compressor generally includes air receiver, dryer and filter. Different models and operating conditions have different types of post-treatment equipment. The specific methods are
