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.
Oil-free air compressors are often used in production and life. Many companies will purchase them, but there are some parameters that need to be understood when purchasing. The precautions for choosing oil-free air compressors are as follows: 1: First of all, you must choose a truly oil-free air compressor. There are many types of oil-free air compressors on the market, but there are not many that can be completely oil-free, granklin water lubricated air compressor when running
Single screw air compressor and twin screw air compressor difference in the world, in addition to the micro compressor, in the power with air compressor, more than 70% for the twin screw air compressor. Compared with the single screw air compressor, the performance of the new machine is not much different, mainly reflected in the performance difference after a period of use.
With the development of science and technology, the requirements for mechanical equipment in industrial production are getting higher and higher. Now many enterprises are using oil-free air compressors to replace traditional air compressor equipment in order to ensure the quality of production. However, oil-free air compressor equipment and ordinary air compressor equipment
Air compressor type variety, wide range of uses, and different types of air compressor, the lubrication requirements vary greatly. In the air compressor parts, the lubricating oil plays a role in preventing wear, sealing, and cooling, minimizing the influence of air on the viscosity of the lubricating oil and the reaction between additives and air, so as
The equipment that integrates components such as freeze dryer, precision filter, gas tank and so on is called integrated air compressor, and it can also be called combined air compressor, which is convenient to install, simple to apply and convenient to move.
Is it difficult to choose an air compressor for industrial use? Among the large air compressors, the "water-lubricated air compressor" produced by Shanghai Granklin Group can achieve 250KW power on a single machine. Industrial use of oil free air compressor choose it:
Before using the air compressor, please read the manual or discuss with the air compressor technician, the equipment is safe and the cost of the enterprise is reduced. Before operating the air compressor, you must be familiar with the following issues: 1. Keep the lubricating oil in the oil pool within the scale range, and the flow rate of the tanker before the air compressor runs shall not be lower than the scale line value.
Which brand of screw air compressor is better? This kind of problem has always been the most concerned and most concerned about the problem of buyers and sellers. It is also the so-called "Wang Po sells melons and boasts", so when choosing the brand of screw air compressor, it must be
View detailsOil-free air compressor three filters mainly include: oil-free air filter, oil-free oil filter, oil-free oil and gas separator. The method of replacing each filter element is slightly different, and we will talk about it separately. The water-lubricated air compressor produced by Shanghai Granklin Group is 100% oil-free.
With the accelerating process of industrialization, the consumption rate of energy resources is also increasing year by year. The shortage of resources has led more and more people to pay attention to environmental protection and energy conservation. Electric cars, ethanol gasoline and so on are energy-saving products. In this strong energy-saving environment, air compressor as an important part of production and life has attracted much attention. Shanghai Granklin Group, in response to social needs, developed a series of energy-saving air compressor, widely praised by users.
