Scroll machine and screw machine have their own advantages and applicable scenarios, can not simply say which is better. Here are some comparisons of them:
efficiency: Screw machines usually have high efficiency, especially under high load and continuous operation. Scroll machines may be more energy efficient under partial load and intermittent operation. This is because the design of the scroll machine makes it more efficient at part load and can be operated at lower speeds. However, at full load and high speed, the efficiency of the scroll machine may decrease because of its internal leakage and friction losses. Because of its design principle, the screw machine can provide high volumetric efficiency and thermal efficiency in the compression process.
Application: Due to its high efficiency and smooth operation characteristics, screw machines are usually suitable for industrial applications that require continuous and high-load operation, such as manufacturing, power and chemical industries. Scroll machines are more suitable for part-load and intermittent operation applications, such as small factories, laboratories or offices. In addition, the scroll machine can produce gas without oil, which greatly improves the quality of compressed air. Therefore, in some occasions with high air quality requirements, the scroll machine may be more popular.
Stability: screw air compressor and scroll air compressor stability is good, low failure rate. However, due to fewer moving parts, the scroll air compressor has less wear and tear for long-term operation, and its service life may be longer. In addition, the noise of the scroll air compressor is usually low because of its low operating speed.
Occupying area: due to the small gas production of the scroll air compressor, the equipment itself is small, and the internal space can be set more compact, so the occupied area is small. This may be an advantage for applications where space is limited.
In summary, the choice of a scroll machine or a screw machine depends on the specific application needs and scenarios. If continuous, high-load operation is required and air quality is not required, a screw machine may be more suitable; if intermittent operation is required, air quality is required, or space is limited, a scroll machine may be more advantageous. When choosing, it is also necessary to consider the acquisition cost, maintenance cost and operating cost of the equipment.
The drainage period of the air storage tank of the air compressor needs to be dynamically adjusted according to the environmental conditions, operating conditions and equipment configuration. The specific suggestions are as follows: 1. the environmental conditions to affect the high humidity environment in rainy season or humid areas: drain water 1-2 times a day to prevent condensate from flowing back to rust the main engine.
Condensed water will be produced during the operation of the air compressor. If it is not treated in time, it may cause equipment corrosion and compressed air quality degradation. The following is a systematic scheme for drainage treatment: the causes and hazards of 1. condensate air is compressed
There are significant differences between the air compressor integrated machine and the split machine in many aspects, which are mainly reflected in the structure, ease of use, application scenarios and maintenance costs. The following is a detailed analysis of the difference between the two: 1. structure difference one
The oil content of compressed air can be divided according to different standards, including international standard ISO8573, European standard DINISO8573 and other application-specific standards. The following are the oil content levels of compressed air according to these standards:
The maintenance cycle of the screw machine can be determined according to a number of factors, including the use environment of the equipment, the frequency of use, the condition of the equipment, etc. Generally speaking, the maintenance of the screw machine can be divided into daily maintenance and large maintenance. Daily maintenance: the recommended cycle is 1~2 months
The replacement cycle of the oil core of the air compressor is usually between 2000 and 4000 hours, but it also depends on some interesting factors. For example, if our air compressor works in a relatively "difficult" environment, such as high temperature, high humidity, or
