Screw air compressor in the choice of purchase, the need to assess several aspects of the parameters, in order to ensure that the choice of more suitable.
1. Compressed air quality of screw air compressor
according to the requirements of industry gas equipment for compressor gas, screw air compressor and supporting equipment should be selected appropriately. The following points need to be considered:
1) To reduce the oil content in the compressed gas, a degreasing purifier can be used. If the treatment index is high, multi-stage treatment can be selected.
2) To reduce the water content in the compressed gas, water removal equipment can be used.
2. Exhaust pressure
the greater the exhaust pressure of the screw air compressor, the more energy consumption. The sum of the use pressure, pipeline resistance loss and the pressure drop of the supporting equipment is determined as the lower limit of the rated exhaust pressure of the screw air compressor. Under normal circumstances, the diameter of the gas pipeline should be larger. In order to reduce resistance loss and achieve the purpose of reducing energy consumption in long-term operation. The greater the discharge pressure of the compressor, the more energy consumption. So do not use high exhaust pressure screw air compressor.
3. Screw air compressor displacement
calculate the actual total gas consumption ξ 1.1-1.2 coefficient, as the selection of exhaust volume of the model, such as the selection is too low, can not reach the specified value of gas equipment, the selection is too large, resulting in load reduction energy consumption, load reduction operation is not economical. At the same time, the purchase cost of large displacement screw air compressor is higher.
Combined with the three screw air compressor in the purchase of the need to consider, and then combined with the actual use of the company itself, generally can choose the appropriate screw air compressor.
The oil-free screw air compressor in the factory usually needs to run all day and consume a lot of electricity. Advanced frequency conversion technology not only helps to save energy, but also makes the operation of the air compressor simple and stable. So in the choice of oil-free screw air compressor inverter should pay attention to what?
View detailsThe water-lubricated air compressor produced by Shanghai Granklin Group is oil-free, environmentally friendly and energy-saving. The whole air compressor is made of stainless steel, so the gas compressed by the air compressor is free of oil. Should the gas storage tank keep up with it?
View detailsThe expenditure of using screw air compressor is divided into two parts, the cost of using energy consumption and the cost of purchasing machines. Buy water-lubricated oil-free air compressor and choose a suitable brand. Shanghai granklin group can be selected for a price. Oil-free screw air compressor factory direct, the price can make you more satisfied. Quality, after-sales nationwide to provide high-quality services.
How to properly maintain and maintain oil-free air compressor 1, oil-free air compressor intake air filter element maintenance and maintenance. The air filter is a component that filters out air dust and dirt, and the filtered clean air enters the compression cavity of the screw rotor for compression. Because of the screw machine
Screw compressor is a kind of power equipment widely used in the field of petrochemical and industrial production, and its safe and reliable operation is of great significance to ensure production, so it is necessary to focus on it. A screw compressor is arranged in parallel in the cylinder of the main engine.
The food industry has high requirements for the selection of oil-free air compressors. The oil-free air compressor used in the food industry is usually divided into non-contact, indirect contact and direct contact. No matter which one, it requires the purity and sterility of the air environment, and the reduction of microbial content is strict. Food health is directly related to the health of consumers. Once a bad air compressor is used, the impact on product quality, the threat to consumer health, and the impact on the company's reputation are very huge.
View detailsBuy oil-free air compressor should pay attention to the point: buy oil-free air compressor to consider the safety of air compressor operation. Air compressor is a kind of machine with pressure work, accompanied by temperature rise and pressure, the safety of its operation should be put in the first place. National Air Compressor
What is the price of oil-free and water-free air compressor? Oil-free air compressor does not contain a drop of oil during compression. The air compressor head needs cooling and lubrication, and water is used as the lubricating medium. This effect can be achieved very well. Industrial production often needs to be matched with post-treatment such as cold dryer, suction dryer, precision filter, air storage tank, etc.
In the application of some special scenes of compressed gas, we need to use explosion-proof ability of "explosion-proof air compressor", but most people only know "explosion-proof air compressor", but do not know what is "explosion-proof air compressor".
The primary maintenance of screw air compressor mainly includes the following contents and steps: 1. Check the joint contact and insulation resistance of the electrical part of the air compressor. First, use an ammeter to detect the current value of each item or use an infrared temperature measuring gun to detect the incoming terminal temperature. Do
