Screw compressors are allied products for almost all industrial operations, whether in the food, pharmaceutical, automotive, textile, and more. As screw compressors are such a versatile tool, it is important to make the right investment to avoid having to purchase additional compressors to meet the demand for compressed air in production plants.
In this blog, we present the key principles to take into account to correctly choose a screw compressor.
1.- Establish pressure.
It is important to verify the maximum pressure required by each of the machines and tools to be used in the pneumatic system, as the screw compressors are graduated to a certain power. The lower the pressure, the higher the flow delivered by the compressor.
2- Size of the screw compressors.
When establishing the size of the screw compressor, the air flow is the determining aspect, because with it we ensure that the compressor completely cover the air demand of all machinery. It will be necessary, then, is to review each of the technical data of the (s) machine (s) or tools and in the case of more than one, make a summation to know the total consumption they need.
We have screw air compressors, with a variety of models with variable capacity, according to the requirements of each customer.
We recommend calculating an additional 25% to 40% in the estimated flow, thus avoiding an overload of the compressor and therefore the premature wear of its parts and equipment. On the other hand, a higher flow rate will allow us to compensate for possible air losses caused by the pneumatic network, which reduce the air flow delivered by the compressor.
3.- Determine the daily workload
Depending on the industry and application, it is recommended to determine the daily working hours that will have the compressor. Sometimes, there are economical compressors, which, due to their technical characteristics, are for moderate use. However, our screw compressors are of high quality and support, which reduces the time of preventive maintenance.
One of the indispensable acts in every compressor is the periodic change of filters, such as air filter, oil filter and separator filter. Applying it will allow the compressor to always supply clean and quality air.
