The water lubricated air compressor produced by Shanghai granklin group is widely used in metallurgy, machinery manufacturing, mining, electric power, textile, petrochemical, textile and other industries. Our cases cover all provinces and cities in China.
Oil-free screw air compressor
1. Overview Oil-free screw air compressors are widely used in metallurgy, machinery manufacturing, mining, electric power, textile, petrochemical, textile and other industries. They are the core equipment of many technological processes. Their installed capacity generally depends on the amount of air required for production and an additional 10% ~ 20% margin.
Due to the imbalance of gas used in production, when the gas pressure reaches a certain value, the air compressor generally adopts the two modes of unloading no-load operation or stopping the air compressor.
Among them, the power consumption during unloading no-load operation is 30% to 60% of the full load. This part of the electric energy is wasted in vain, and stopping the air compressor operation will bring frequent start and stop of the motor, which will have a greater impact on the power grid and other equipment. At the same time, the life of the air compressor will be shortened.
Do not use natural solvents such as gasoline or kerosene to clean air filters or other parts. The screw air compressor cannot be started mainly due to the following five points: 1. check whether the fuse is burnt out, 2. the relay protecting the machine has lost its effect. 3. to the poor contact of the start button, this problem is not very common, because the current screw air compressor, unless it is really cheap and buy a very low price of the machine, otherwise it is generally not such a problem, even if there is also a good solution.
We often say that variable frequency air compressors do not save electricity. Loading depends on the specific power and unloading depends on the internal pressure. Specific power is one of the important indicators to measure whether the air compressor is energy-saving. To understand the specific power of a variable frequency air compressor, we must first have a complete understanding of the concept of its input power. The electricity bill to be paid by the user is not the output power consumption of the entire machine, but the input power consumption of the entire machine, that is, the total input energy consumption of the machine.
Many users only care about the immediate purchase cost when purchasing air compressors. I will buy whoever is cheaper. This must be a very layman's practice. The air compressor bought cheaply may consume a lot of electricity. After watching the electric meter fly like a gyroscope, it will make me feel distressed.
The oil-free air compressor should run smoothly and the sound of all moving parts should be normal. There is also the lubricating oil pressure, temperature and oil supply of the oil-free air compressor, which also needs to be observed at all times. The oil pressure shall not be less than 1kg/cm2 before being fed into the distribution piping.
The lubricating oil in the crankcase or fuselage shall be wet: the equipment with crosshead shall not exceed 60 ℃. No crosshead shall exceed 70 ℃. Measure the inlet and outlet water temperature and check the supply of cooling water. The cooling water shall not flow intermittently, bubble and blockage. The drainage temperature of cooling water shall not exceed 40 ℃.
When the oil-free silent air compressor is operated, the safety accessories such as air storage cylinder, safety valve and pressure gauge must meet the requirements of the Ministry of Railways on the safety technology of compressed air storage cylinder. The air filter of the oil-free silent air compressor must be cleaned frequently to keep it unblocked to reduce unnecessary power loss.
When the oil-free silent air compressor operates dusty work such as sandblasting and derusting, the machine should be kept at a certain distance from the sandblasting site, and corresponding dust prevention measures should be taken. The operation of the motor part of the oil-free silent air compressor must comply with the relevant regulations of the motor.
"7.5kw air compressor" in the industrial "industrial screw air compressor" is not big, because as "Shanghai granklin group" production of a larger "air compressor", it has the characteristics of simple maintenance, stable gas supply. Small "air compressor" models are more popular in small and medium-sized enterprises, especially "7.5kw air compressor".
Granklin water lubricated air compressor has a reasonable structure and an ideal force balance: both sides of the screw of the oil-free air compressor are equipped with a star wheel symmetrical structure, so that the oil-free air compressor not only has no unbalanced inertial force, but also The axial force and radial force on the screw cancel each other out, making it have an ideal force balance.
Compressors are classified according to different structural forms as follows: According to their principles, they can be divided into: reciprocating (piston) compressors, rotary (rotary) compressors (turbine, water ring, turbine) compressors, and axial flow Compressors, jet compressors and screw compression
The oil-free air compressor is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy, and is a pressure generating device for compressed air. Attention to the use of oil-free air compressor 1. When the oil-free air compressor is shut down due to power failure, in order to prevent the compressor from starting under pressure, when starting up again
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.
There are several possible reasons for the overload of air compressor: 1. The main engine or motor is blocked or the bearing is damaged. 2. The power supply voltage is too low. 3. Missing phase operation. 4. Poor contact of the main power supply or contactor. 5. The oil filter or oil-gas separator is blocked.
The competitiveness of domestic air compressors in the global market has become stronger and stronger in recent years, thanks to the upgrading of the entire domestic industry. In the past like to buy imported air compressor, different times more and more enterprises began to choose to buy domestic air compressor.
We may not know, in fact, the maintenance of air compressor can be divided into four stages, according to the time node, is divided by day, month, quarter, year. Basically, the daily maintenance is to pay attention to check whether the exhaust port temperature of the host is abnormal.
The oil-free air compressor produced by Shanghai Granklin Group can compress the gas to meet the oil-free standard. Many industries with high requirements for compressed air can purchase water-lubricated air compressors: clean and dry, not allowed to contain water, oil, dust, etc. Therefore, purification of compressed air is an essential means of industrial production. Compressed air dryers and matched compressed air filters are the most effective methods for drying and filtering compressed air.
View detailsThe difference between oil-free air compressor and oil-free air compressor is: different materials, different final discharge of gas, and different life. Different 1. materials: 1. Oil-free air compressor: the material of oil-free air compressor contains oily substances, which will pollute the terminal equipment; 2. Oil-free air compressor: the material of oil-free air compressor does not contain oily substances, thus avoiding the pollution of oil-free air compressor to terminal equipment.
