The piston type is directional, and the phase sequence protector must be installed. In case the circuit phase sequence changes, it will protect it and not work. The spiral type is good, it has no direction, the wiring direction is not specified, and the work is stable.
The piston type is directional, and the phase sequence protector must be installed. In case the circuit phase sequence changes, it will protect it and not work. The spiral type is good, it has no direction, the wiring direction is not specified, and the work is stable. At present, the central air-conditioning screw air comperssor on the market takes the twin-screw compressor as the mainstream, the compression mode of the twin-screw compressor is two screw meshing with each other for compression, and the piston machine is a kind of round-trip compression.
The piston air compressor basically has no automatic control system, and the screw compressor has a perfect automatic control and protection system. It is a mechatronic product, which facilitates the maintenance and management of the equipment and reduces the energy consumption to a large extent. Piston machines are generally classified by exhaust pressure, exhaust volume (volume flow), structural type and structural characteristics.
When the piston machine completes each working cycle, the change process of the gas in the cylinder is very complicated. In order to facilitate the study of the problem and simplify the influence of secondary factors, several assumptions are put forward in theory, and the working cycle completed by the piston air compressor under the assumed conditions is called the theoretical working cycle.
As the screw air compressor has been fully intelligent control, high-precision electronic sensors accurately collect a variety of data, so that the machine in accordance with reasonable pressure requirements, running time, self-protection completely self-management. Its management costs are much lower than piston compressors.
Since the oil content of the screw air comperssor is lower than 3ppM, which is far lower than the oil content of the piston compressor (lower than 10ppM), the service life of the back-end air source processing equipment is greatly extended, and the pneumatic equipment and tools are also protected. The installation of the piston machine needs to be made of cement foundation and circulating water (the large piston machine has no air cooling type and needs water cooling), thus the installation cost is higher.
