When we have the preparatory work ready, oil-free air compressor can be started according to the following procedures:
1. Check whether the rotor and stator have abnormal phenomena such as friction and collision, and confirm that the rotor is flexible;
2. Slowly lift the starter handwheel to make the steam open the valve quickly. When the power oil pressure difference at both ends gradually increases, it opens quickly and the steam enters the speed regulating valve chamber.
3. Continue to lift the starter handwheel, generate secondary oil pressure, and apply force to the oil motor slide valve. When the secondary oil pressure rises to some value, the slide valve, under the action of the secondary oil pressure, rolls the power oil to the channel of the upper chamber of the oil motor piston for communication, the power oil enters the upper chamber of the oil motor piston, opens the speed regulating valve, the steam enters the turbine through the nozzle, and the unit starts to rotate;
4. When the rotating speed of the unit rises to 100 rpm, it is said to run for 15min. When it is confirmed that there is no abnormality, it shall be carried out according to the procedure.
5. Continue to lift the starter handwheel until it reaches the highest position.
6. After the starter function is finished, the governor is put into normal operation to play its speed adjustment function.
The advantages of oil-free air compressor: oil-free air compressor has low noise, which solves noise pollution, and oil-free air compressor solves the phenomenon of compressed gas oil and water. The machine itself contains a water outlet, which can discharge the water in the gas tank. Increased service life. At the same time, the oil-free air compressor does not need lubricating oil, which reduces the cost of purchasing lubricating oil.
What is a medical mute oil-free air compressor refers to the kind of air compressor suitable for use under medical environmental and sanitary conditions. It requires precision, stronger reliability, environmental protection and tranquility, fresh and clean compressed air, and the output gas can directly contact the human body. Medical air compressors with a displacement of less than 1m 3/min are mostly micro-screw reciprocating.
Air compressors are used in various production fields. Due to the different quality of equipment, they will be reported for repair more or less. Common faults mainly include high-temperature shutdown, frequent loading and unloading, and failure to start when the voltage is too high. When the air compressor fails
The simplest point is to see whether it contains a frequency converter, and the second is to see whether the motor changes its speed according to the actual working conditions during operation. There are many factors to look. Speed directly affects the oil pressure and high and low pressure. I can see whether there is frequency conversion in current or not. Literally understood, the speed of the variable frequency air compressor is almost the same as the fixed frequency under the working state. When the air compressor is not in the pumping state, the motor frequency will automatically drop and the input power will be reduced to achieve the effect of energy saving.
The perfect air compressor does not exist, has the ability to continuously improve the air compressor technology manufacturers, constantly improving equipment, through service to achieve relative perfection. At present, all manufacturers of permanent magnet variable frequency air compressors are basically doing it. Only when they are used can they know which brand and manufacturer are good.
It is understood that the use of screw air compressor users more or less, or large or small are almost experienced host or motor overload. When the screw air compressor is running under unloading conditions, its energy consumption rating is 30%-40%. The energy saving effect of permanent magnet motor is better than that of power frequency and ordinary frequency conversion in the case of low load.
If the maintenance of the air compressor is not timely, it will have a great impact on the air compressor. The screw air compressor will have a first guarantee for 500 hours of operation and a maintenance for 2000 hours after operation. Screw air compressor oil is good or bad on the oil injection screw
A good brand is managed by heart, and the screw air compressor depends on the after-sales ability of the manufacturer, and the supply of product accessories is long-term. The first choice for purchasing oil-free air compressors is to make some reputation in the industry, with as many cases as possible and perfect after-sales spare parts.
China is rich in coalbed methane resources. Accelerating the development of coalbed methane can not only alleviate the contradiction of natural gas shortage, but also ensure the safety of coal mines and reduce air pollution. Choosing air compressor for coalbed methane project, the better choice is to choose the current market
1. license project name: special equipment use registration, pressure vessel. 2. setting basis: Article 25 of the Regulations on Safety Supervision of Special Equipment: "Before or within 30 days after special equipment is put into use, the unit using the special equipment shall report to the special equipment safety supervision and management department of the municipality directly under the Central Government or the city divided into districts.
