Application of screw air compressor for water treatment

In the past water plant construction, we generally choose the piston screw air compressor. The piston screw air compressor has the advantages of low investment cost and large compression ratio, but at the same time, the screw air compressor also has many moving parts, easy to wear, and large maintenance workload.

There are two two-stage air-cooled oil-free piston screw air compressors, which have been in use for less than half a year. Various problems have arisen one after another, such as excessive wear of piston rings and pistons of piston air compressors, excessive wear of inlet and outlet valve plates and valve seats, and oil leakage of oil control system. Moreover, the air production of the piston air compressor is obviously insufficient, and the machine is in a loading state for a long time and cannot be unloaded, thus increasing its own wear.

Through extensive understanding of the screw air compressor and comparison, the final selection of the screw air compressor. After use, it is found that the screw air compressor is not only easy to operate, but once the various operating parameters of the screw air compressor are set, the screw air compressor can be completely controlled and monitored by its own computer controller.

These characteristics of the screw air compressor are related to the unique host structure and working mechanism of the screw air compressor, and are also closely related to the reasonable system design and intelligent electrical control system of the screw air compressor itself.

A prominent feature of the electrical control system of the screw air compressor is the high degree of intelligence, and the man-machine interface of the screw air compressor is simple and friendly.

It takes a computer controller and its control panel as the control center, takes the analog signal of the outlet temperature sensor of the compressor host and the pressure sensor of the air supply port of the screw air compressor and the switching signal such as motor overload as the main input, runs the built-in control program through the screw air compressor, and outputs the electrical signal to trigger the conventional electrical control element to realize the control of the screw air compressor.

From the main structure and working mechanism of the screw air compressor, it is not difficult to see that the screw air compressor has fewer moving parts. The screw air compressor has only a pair of intermeshing rotors (there is an oil film between the rotors). The screw air compressor does not have a reciprocating piston mechanism similar to a piston machine and a complex inlet and outlet valve mechanism, so the screw air compressor has little wear, more reliable operation and long life.

Secondly, the operation of the main engine of the screw air compressor is similar to that of the turbine machine. The screw air compressor has no unbalanced inertial force, and the gas compression of the screw air compressor is continuous without impact. The machine can work smoothly and at high speed without special equipment foundation.

In addition, the noise of the screw air compressor can be reduced to a lower level.
