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.

The piston screw air compressor has the advantages of low investment cost and large compression ratio, but at the same time, the piston 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.

Shenzhen screw air compressor which is good, Shenzhen screw air compressor brand which is good screw air compressor compression components can ensure that the temperature of the equipment and compressed air temperature are maintained at a low state, Shenzhen screw air compressor which is good for internal components
Twenty-first Century air compressor market competition is fierce, consumers in the purchase of products, often the machine quality and price included in the purchase standard. Therefore, this article will be common in the market a variety of labeling methods to make a description, in order to protect the interests of consumers to do a force.
In order to make the oil-free air compressor can run normally and reliably and ensure the service life of the unit, a detailed maintenance plan must be formulated, and the fixed person operation, regular maintenance and regular inspection and maintenance must be carried out to keep the oil-free air compressor clean, oil-free and dirt-free. Main Department
Choose air compressor according to the needs of different industries and working conditions, there are corresponding standards. Then how to choose a suitable oil-free air compressor? 1. First figure out what is an oil-free air compressor and why should it be used? The oil-free air compressor has been running
As we all know, air compressors account for more than 70% of the industrial electricity consumption, which belongs to the "big tiger" in industrial electricity consumption ". With the rapid improvement of the national economy, as an important part of the general machinery industry-compressor
The water-lubricated oil-free air compressor has the characteristics of energy saving, environmental protection, stability and durability. It has been widely used in many industries, and the maintenance and maintenance of oil-free air compressors are also concerned by users. The correct daily maintenance and use, can be extended.
In an increasingly competitive industry, customers are often misled by lower air compressor prices and buy an air compressor with low price but poor quality. Here is a brief introduction to the relevant knowledge about the price of air compressor.
