The air compressor in the sewage treatment plant is the key equipment to ensure the smooth operation of the sewage treatment process, mainly by providing compressed air to drive a variety of core process links, which use. Air compressor without oil and water lubrication technology because of its environmental protection characteristics, it has more advantages in the application of sewage plant. The following is the specific function and the suitability of water lubricated air compressor:
the environment of the sewage plant is humid and corrosive gas may exist. The traditional oil-lubricated air compressor is easy to pollute the water quality due to oil leakage, or the deterioration of lubricating oil will affect the service life of the equipment. And air compressor without oil and water lubrication these issues are addressed by the following features:
zero risk of oil pollution
water lubrication technology completely replaces lubricating oil, prevents oil from entering sewage or pneumatic system from the source, and prevents:
Adapt to wet environment
the water-lubricated air compressor has a simple structure, and the oil-free system reduces the problem of lubricating oil emulsification and deterioration caused by moisture, and the operation is more stable.
Low maintenance costs
there is no need to regularly replace lubricating oil or deal with waste oil, and only simple maintenance of water-lubricated components (such as water quality cleaning) is required to reduce long-term use costs.
Energy saving and mute
some water-lubricated air compressors adopt frequency conversion technology to automatically adjust the power according to the gas demand to reduce energy consumption; at the same time, the operating noise is low to improve the working environment of the sewage plant.
dew point control
some processes (such as aeration) of the sewage plant require high air dryness, and drying equipment should be matched to further reduce the dew point of compressed air to prevent the accumulation of pipeline condensate.
gas supply stability
according to the scale of the sewage plant, select the air compressor with appropriate displacement, and configure the gas storage tank to buffer the fluctuation of gas consumption, so as to avoid the influence of process continuity due to insufficient gas supply.
Corrosion resistant design
it is preferred to select air compressors with corrosion resistance (such as stainless steel pipes) to adapt to the acidic or alkaline gas environment that may exist in the sewage plant.
Through the reasonable configuration of oil-free water lubrication air compressor, sewage treatment plant can not only meet the demand of pure compressed air, but also reduce the operation risk and maintenance cost, and achieve the goal of efficient and environmentally friendly sewage treatment.
There is a close relationship between air pressure and air volume, which affect each other and jointly determine the performance of the air compressor. The following is a detailed explanation of the relationship between air pressure and air volume of air compressor: definition of air pressure and air volume: air pressure: refers to the pressure of compressed air
The standard of compressed air in the machining center mainly includes the following aspects: Pressure stability: The compressed air used in the machining center needs to maintain a stable pressure output. In general, the pressure should be between 6-8bar, there are also requirements pressure in 0.7-1.0 MPa (MPa)
在制药发酵过程中，使用的压缩气体确实需要是无油的，这主要基于以下原因和行业要求：一、无油压缩气体的必要性 防止药品污染 制药发酵过程中，压缩空气直接接触菌种、培养基或药品
The air compressor cannot be started immediately after shutdown, which may be caused by the following reasons: 1. electrical problems power supply problems: unstable or too low voltage: the supply voltage of the screw air compressor is too low, and the undervoltage of the power supply will cause the motor to fail to start normally. Motor supply voltage in
20m & sup3; The power of the air compressor is not fixed, it is affected by many factors, including working pressure, brand, model and mechanical efficiency. The following is a detailed analysis and summary of 20m & sup3; air compressor power: power range: general
In the cleaning process of the electronic industry, compressed air must meet the core standards of ultra-low oil content (≤ 0.003 mg/m & sup3;), extremely low particle pollution (particle size ≥ 0.1μm particle number <1000/m & sup3;), deep drying (pressure dew point ≤-70 ℃ or even -100 ℃)
The role and use of air compressors in chemical plants mainly include the following aspects: 1. function: power supply: air compressors can be used as power after air compression, which is the most basic role of air compressors in chemical plants. Many chemical machinery are required
The water supply of the water-lubricated air compressor is controlled by the system. The water vapor cylinder will replace the pure water many times to replace the water in the head of the water-lubricated air compressor. Water replenishment is not performed at one time. Without affecting the work of the water-lubricated air compressor head, the lubrication water can be replaced many times to achieve the purpose of automatic water replenishment.
Q: scroll type and screw type which is the most advanced? A: scroll type and screw type air compressor have their own advantages and scope of application, can not simply judge which is more advanced. The principle of scroll air compressor determines that it can only be used in small models (15KW and below)
In the air compressor industry, permanent magnet frequency conversion technology has become the key technology to improve energy efficiency and stability. So, which brand of permanent magnet variable frequency air compressor is better? This article will focus on the water-lubricated screw air compressor produced by Shanghai Grankering Group, with its
