screw air compressor use skills?

There is a complete set of procedures for the installation of screw air compressors. Although the standards of various manufacturers are different, the general steps are similar. On the basis of summarizing the installation and debugging experience of many air compressors, the author now writes down the general steps and matters needing attention in an article to provide reference for peers to smoothly carry out the installation and debugging of air compressors.

The installation and commissioning of air compressors is a basic work, which is related to the future use of equipment: it is also a systematic project, from pre-sale, sale to after-sale, installation and commissioning work is very important and not simple. Affect the installation and commissioning progress and quality, including not only the air compressor equipment itself, but also the professional quality of the installation and commissioning personnel and the skill level of the operator.

The installation and debugging of the screw air compressor is not only a test for the air compressor manufacturer, but also a test for the user. For manufacturers, it is very important whether the equipment passes the customs and whether the debugging personnel have the ability and experience. For users, whether the equipment selection is appropriate, whether the layout is reasonable, whether the infrastructure is qualified, and whether the follow-up training can keep up are all a big test.

Selection of 1. air compressor

selection is the first step in the procurement of air compressor. Each manufacturer has different requirements for the air supply and compressed air quality of the air compressor. The manufacturer selects the air compressor supplier through various channels or bidding procedures. After selecting the manufacturer and brand, the individual should go to the manufacturer for inspection. After the inspection, the contract is signed. After a month or so, the air compressor manufacturer placed an order for the manufacture of the air compressor, which can be supplied directly if the manufacturer has inventory.

Preparation before 2. installation

after the contract is signed, air compressor manufacturers and users will enter the preparation stage of equipment installation. The larger air compressor, the preparation time is longer, the smaller air compressor, the preparation cycle is naturally shorter. 3. installation and commissioning

installation

after the screw air compressor arrives at the user's place, the installation is relatively simple, because it does not need to be the foundation of the base like the piston machine, and the piston machine must be fixed with large screws. Screw machine as long as the air compressor on the base of the machine or flat ground can be. However, in the process of installation and commissioning, we should pay attention to the changes of various details to prevent unnecessary accidents and make the installation and commissioning work orderly and effectively.

The installation of the air compressor should follow the relevant local laws and regulations, and strictly abide by the following regulations:

1. The air compressor shall be lifted by lifting equipment with load-bearing capacity greater than the weight of the unit, and the lifting speed and acceleration shall be limited within the permitted range;

2. Try to install the air compressor in a cool, clean and well-ventilated place to ensure that the air sucked by the air compressor is clean and has the smallest moisture content;

3. The air sucked by the air compressor is not allowed to contain combustible gas and corrosive gas, so as not to cause explosion or internal corrosion;

4. Air-cooled machines should preferably have exhaust fans or air ducts to export hot air to the outside to avoid hot air circulation to the air inlet;

5, air compressor sewage, waste oil discharge should comply with the provisions of the local environmental protection department;

6. The power supply line of the air compressor must match its power and install safety devices such as air switches and fuse wires. In order to ensure the reliability and safety of electrical equipment, it must be reliably grounded.

In addition, before the start-up, the pipeline laying should be prepared, the valve opening state of the pipeline system should be checked, and the vent valve should be closed. Some air compressors with post-processing devices sometimes require post-processing manufacturers to operate on site. After the inspection is correct, the equipment can be commissioned.

The following points should be noted during commissioning and operation;

1, the new machine debugging, must be designated by the company or approved debugging personnel;

2. Before starting up, make sure that there is no one in the unit, check whether there are any items and tools left behind, and close the unit door: when starting up, notify the personnel around the unit to pay attention to safety;

3. During the test run, strictly check the running direction of the air compressor. When it is found to be reversed, stop the machine immediately, cut off the power supply, and switch any two of the three-phase lines to restart the machine, otherwise it will damage the air compressor. [Pay attention to every time the factory power supply is overhauled!);

4. The air compressor cannot work under the exhaust pressure higher than the nameplate, otherwise it will cause the motor to overload and burn out:

5, when the air compressor is in remote control, the machine may start at any time, should be listed to remind;

6, when the air compressor failure or there are unsafe factors, do not force the boot, at this time should cut off the power supply, and make a significant mark.

4. management and training

the training of operators includes the training of technicians and management personnel, which is taught by sales personnel or after-sales personnel. The main contents of the lecture include the structural principle of the air compressor, equipment maintenance, maintenance and troubleshooting. Good conditions can be used to explain the courseware projection equipment, and combined with the actual equipment to explain. Operators training in various forms, the time can be long or short, according to the need for multiple training.

The installation and debugging of air compressor is important and complicated. It is necessary to install carefully, check orderly and parts effectively. To ensure the quality of work and improve performance, it is also necessary to strengthen training and training assessment in order to provide users with efficient and high-quality screw air compressor products.
