In the complete pneumatic system, in addition to using the
custom screw air compressor to produce compressed air, post-treatment equipment is also required to cool, dry and purify the 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 as follows:
1、 The volume of the air receiver shall be about 1/6 of the compressor discharge, which can be appropriately enlarged according to the working conditions.
2、 The precision filter can be divided into several levels according to the filtering accuracy. For example, the precision filter of Krupp air compressor can be divided into four levels: C, T, A and H. Among them, C is the primary filter, and H is the level with the highest filtering accuracy. Generally, three-stage filters can meet the user's requirements, while special industries such as pharmaceuticals and electronics need to use four or five stage filters.
3、 The processing capacity of the dryer shall be consistent with the exhaust capacity of the air compressor. The filter before the dryer shall be equipped with an automatic drain. When the compressed air with dryness of - 70 ℃ (dew point) is required to be supplied by the gas equipment, the heating regeneration type is generally adopted; If it is required to supply dry air at about - 40 ℃, the heatless regeneration type is generally adopted; When the gas equipment requires win-win dry air of about - 20 ℃, it is better to choose a frozen compressed air dryer. The lower the pressure dew point, the higher the quality, which can be selected according to the gas requirements of the enterprise.
When the dryer is installed behind the air receiver, the role of the air receiver is fully reflected, which plays the role of buffering, cooling and blowdown. At the same time, it can reduce the load of the dryer, which is used for the working condition of uniform air supply of the system. The dryer is installed in front of the air receiver, and the system can provide large peak adjustment capacity, which is mostly used for the working conditions with large gas consumption fluctuations.
We all know the importance of
China wholesale Oil free rotary screw air post-treatment equipment. It can remove water, oil and impurities in compressed air, eliminate gas pulse, cool compressed air, etc., ensure the quality of compressed air, and maintain great reliability of pneumatic system. It is very necessary to correctly select post-treatment system of air compressor.
PRODUCT FEATURES
UItra-low frequency speed control technology far surpasses standard VSD compressor systems.Capable of lower than 15Hz operation，this system is truly capable of constant variable pressure operation and significant energy saving.
USoft-start feature allows for little or no impact on the power supply system and marginalises mechanical wear and tear up on start-up.
Leakage is always present in any air system.At full pressure a good system can loose 0.2Mpa.Zerlion VSD machines can reduce that loss by up to 25%simply by supplying the air pressure that is required.
Advanced Vector variable frequency control reduces vibration and noise.The unit can be used without the requirement for a special room.
This means saving of all resources required to install a machine in an external location such as pipe and power lines and land.Oil exhaust output is lower than 3ppm thus negating enviromantal impact.
Utilising frequency control for the cooling fan and drive motor allows for up to 30%energy savings.This translates into less frequent servicing of the screw compressor thus further significant savings are achieved over the life of the machine.
