how to rightly choose Air dryer

　　According to customer demand for born to air compressor gas quality! Overview of the classification of the air dryer and its unique performance, let more customers know the air dryer, the proper use of air dryer equipment.

　　Air drying is divided into two categories: A, frozen type air dryer; B, adsorption type air dryer; The two drying working principle is different, difference effect is different also.

　　Frozen type air dryer for some requirements for compressed air quality generic company add several pipeline filter is enough, the main thing is that can save cost. For example:  Plastic factory and hardware companies, environmental protection products factory and so on

　　Adsorption type air dryer is used to strengthen the frozen type air dryer after processing of air quality, is the production of high precision products essential purification equipment. For example: the placement machine equipment, electronic products, LED lamps factory and other companies.

　　Shanghai DENAIR compressor co., LTD., production research and development of the series products are: water-cooling screw air compressor, air cooled screw type air compressor, oil free screw air compressor, variable frequency screw air compressor , the permanent magnet screw air compressor variable-frequency screw air compressor, small air compressor etc.air compressor products.

Air tank usage

　　Pressure tank means it contains gas or liquid, carrying a certain pressure hermetic device. Its use significantly in industry and has brought great convenience, also contributed a lot to scientific research in China. Below I will introduce to you specific pressure tank usage.

　　Pressure vessel piggy tank usage is very wide.It's very important equipment in petroleum chemical industry, energy industry, scientific research and military industry, etc. Every part of the national economy plays an important role in . Pressure vessel piggy bank generally consists of cylinder, head, flange, sealing element, opening and took over, bearing and so on six big parts container body. In addition, also equipped with a safety device, the meter and the internal parts of different production process effect. due to Pressure tank easy explosion, burning a fire and endanger the safety of the personnel, equipment and property and environmental pollution accident.every countries look as a important inspection the product around the world, by the specialized agencies designated by the state, for the supervision and inspection in accordance with the laws and regulations and standards prescribed by the state and technical inspection.

How to choose suitable air compressor?

　　how to choose suitable air compressor? let DENAIR group enginner tell you . you should consider the following four factors:

　　First,Work pressure, exhaust pressure selection:

　　When users ready to air compressor unit of choose and buy, the first thing to determine the working pressure of gas side need, add 1 to 2 bar allowance, then choose the pressure of the air compressor, (the allowance is considered from the air compressor installation location to the actual gas pipeline pressure loss of the distance, according to the length of the distance between 1-2 bar pressure due consideration allowance). of course, the size of the pipe size and how much is turning point of the factors affecting the pressure loss, the bigger the pipe size and the turning point is less, the smaller the pressure loss; Conversely, the greater the pressure loss.

　　Therefore, it's too far distance between the compressor and the gas side line, should be properly enlarge head the size of the road. If environmental conditions to meet the requirements of the installation of the compressor and the condition allows, can be installed on the gas side of things.

　　second,　Volume flow selection:

　　(1) when choosing air compressor volume flow, should first understand all of the volumetric flow rate of gas equipment, the total number of the traffic multiplied by 1.2 (i.e., enlarge 20% allowance);

　　(2) the new project according to the design institute for selection of flow value;

　　(3) ask the gas equipment suppliers the selection of gas volume flow parameters of the equipment;

　　(4) air compressor station reconstruction may refer to the original parameter value selection in combination with the actual gas;

　　Users themselves on the appropriate selection, and for all air compressor equipment, selection of too much waste, selection is too small may cause air compressor in a loading state for a long time or not enough gas or pressure dozen don't go up, etc.

　　third,Power and the relationship between the pressure and volume flow

　　In the case of power is constant, when the speed change, volume flow rate and pressure of work also change accordingly; For example: a 22 kw air compressor, determine the working pressure of 7 bar during manufacturing, technology curve calculation according to the compressor speed, displacement of 3.8 m3 / min; When determine the working pressure of 8 bar, speed must be reduced (or drive electrical overload - at this time, the displacement of 3.6 m3 / min; Because, speed decreased, exhaust also reduced accordingly, and so on.

　　Power selection is under the condition of meet the work pressure and volume flow rate, power supply capacity can meet the matching the use of the drive motor power.

　　Matching air compressor, therefore, the steps are: first to determine the working pressure, and then set the corresponding volume flow, finally, the power supply capacity.

　　Fourth， to consider the safety of the compressor operation. Air compressor is a kind of machine with work pressure, with temperature and pressure at work, the safety of its operation to in the first place. The state shall implement a compressor production standardization of "two card" system, namely the compressor production license and pressure vessel manufacturing license (reservoir). Therefore, when the compressor products of choose and buy, want to strict censorship "two card". Usually has the factory product quality assurance system is perfect, won't appear the quality problem of the large, even if some problem, also the manufacturer shall be responsible for 3 packets.

How to do energy saving air compressor maintenance

　　How to do energy saving air compressor maintenance? In recent years due to the state advocates energy conservation and emissions reduction, how to effectively improve the utilization rate of resources has been more and more people's attention, in the face of all walks of life both in positive and effective energy saving measures, due to its advantages of energy saving energy saving air compressor has been widely used, in order to make the air compressor can be run normally, we must master the air compressor maintenance and maintenance knowledge, below small make up on how to introduce you to energy-saving air compressor maintenance?
　　(1) to replace the air filter and the intake valve don't let any sundry in energy saving air compressor host cavity.
　　(2) the operation and energy saving air compressor machine will host entry closed, after the operation, to a few turns with the hand, can determine the normal run time to boot.
　　(3) if the energy-saving air compressor belt loose, must adjust to the belt tension.
　　(4) environment, humidity, and whether to have acid-base gas in the air, is the key to determine oil replacement time.

screw air compressor maintenance

　　Screw air compressor risk of failure is less than the piston air compressor , but if you use wrong screw air compressor maintenance, it is hard to get to play the advantages of the screw air compressor. Many users began to change  use screw air compressor instead of  piston air compressor , due to the use of screw compressor maintenance don't understand, cause frequently break down, causing conflict between users and enterprises. So before use screw air compressor ,you need to read carefully screw air compressor maintenance instructions .

　　For machine installation site, air compressor station of the specifications of the ventilation rate, power supply cable, and air switch, pressure and flow rate of water supply, exhaust line size has a guidance. Instruction manual will also has a detailed description to the principle and structure of the machine, have certain basic knowledge of mechanical and electrical personnel through careful reading, can completely to rightly deal with and make judgment for common problems. And screw compressor consumable part needs to be changed on a regular basis are mainly oil, oil filter, air intake filter, oil filter, etc. It is worth noting that in different parts of the environment change of frequency is also different, so to keep daily use of screw compressor and inspection records.Do a good job in every step of the screw air compressor maintenance.
