Main technical data
Cylinder
All the cylinders comprise upper plate, diaphragms, and cylinder body etc. The diaphragms are clamped between the cylinder cover and cylinder body. The cylinder cover and cylinder body each has a concave recess hollowed out in their contacting faces. The gas cylinder is formed between cylinder cover concave recess and diaphragms. Both suction valve and discharge valve are fitted on the upper plate. Among of them, the discharge valve is located on the center of the upper plate. The evenly located small oil holes are on the cylinder body to deliver the oil pressure inside the oil cylinder to the bottom of diaphragms (each diaphragm compressor’s cylinder has 3 piece diaphragm.)
Pressure Regulating Valve
The oil pressure of oil cylinder is regulated by the tension of the valve spring.In case the oil pressure is higher than the regulated value, turn the regulating bolt counter-clockwise to loosen the spring tension, but turn the regulating bolt clockwise to tighten the spring, when the oil pressure is lower than the regulated value. When the oil pressure meets the required value, the regulating bolt must be locked with a lock-nut. The oil pressure of the oil cylinder shall always be higher than the discharge pressure by 15~20%. But the oil and gas differential pressure shall not be lower than 0.3MPa or higher than 1.5MPa.
Cooler
The cooler structure is the double-wall pipe type. The circular space between the outer and inner pipe is the cooling water passage and the inner pipe is the gas passage. Normally the water inlet port is at the lower side and the water outlet port is at the upper side. The flow direction of cooling water and gas is on the contrary.
Oil Pressure Measuring Device
The measuring device of oil cylinder discharge pressure consists of shock-proof pressure gauge, check valve and unloading valve. The case of the pressure gauge is totally airproof and filled with damping liquid. The inner devices of gauge is immersed in the liquid, which makes the pressure gauge hands stable through the function of the viscosity of damping liquid. The unloading valve is fitted under the gauge to discharge the remained air in the oil pipeline and to unload the oil pressure gauge. Also the check valve connecting with oil cylinder through pipeline is fitted under the unloading valve.
Oil pipes
Oil pipes consist of lube oil pipe and oil pressure secure system.
The lubrication for the driving device adopts gear oil pump circulation pressure lubricating. The lube oil stored in the frame oil tank enters into the gear oil pump after being filtered and is pressed into the oil holes in the crankshaft through the gear oil pump to lubricate the crankshaft friction surface. At the same time, part of the lube oil reaches the crosshead pin and crosshead along the oil holes in the connecting rod to lubricate the friction surface. The oil pressure of gear oil pump shall be kept between 0.3~0.5Mpa, and the bearings at the 2 ends of crankshaft is splash lubricated.
Oil pressure secure system consists of oil compensating pipe, pressure-measuring pipe and oil return pipe. The oil output from the oil compensating pump will supplement oil for compressor cylinders through the oil compensating pipe and the excess oil returns to the crankcase through the pressure-regulating valve.

Can air compressors be used for painting and sandblasting?
Yes, air compressors can be used for both painting and sandblasting applications. Here’s a closer look at how air compressors are utilized for painting and sandblasting:
Painting:
Air compressors are commonly used in painting processes, especially in automotive, industrial, and construction applications. Here’s how they are involved:
- Spray Guns: Air compressors power spray guns used for applying paint coatings. The compressed air atomizes the paint, creating a fine mist that can be evenly sprayed onto surfaces. The pressure and volume of the compressed air impact the spray pattern, coverage, and overall finish quality.
- Paint Mixers and Agitators: Compressed air is often used to power mixers and agitators that ensure proper blending of paint components. These devices use the compressed air to stir or circulate the paint, preventing settling and maintaining a consistent mixture.
- Airbrushing: Air compressors are essential for airbrushing techniques, which require precise control over airflow and pressure. Airbrushes are commonly used in artistic applications, such as illustrations, murals, and fine detailing work.
Sandblasting:
Air compressors play a crucial role in sandblasting operations, which involve propelling abrasive materials at high velocity to clean, etch, or prepare surfaces. Here’s how air compressors are used in sandblasting:
- Blasting Cabinets: Air compressors power blasting cabinets or booths, which are enclosed spaces where the sandblasting process takes place. The compressed air propels the abrasive media, such as sand or grit, through a nozzle or gun, creating a forceful stream that impacts the surface being treated.
- Abrasive Blasting Pots: Air compressors supply air to abrasive blasting pots or tanks that store and pressurize the abrasive media. The compressed air from the compressor enters the pot, pressurizing it and allowing for a controlled release of the abrasive material during the sandblasting process.
- Air Dryers and Filters: In sandblasting applications, it is crucial to have clean, dry air to prevent moisture and contaminants from affecting the abrasive blasting process and the quality of the surface being treated. Air compressors may be equipped with air dryers and filters to remove moisture, oil, and impurities from the compressed air.
When using air compressors for painting or sandblasting, it is important to consider factors such as the compressor’s pressure and volume output, the specific requirements of the application, and the type of tools or equipment being used. Consult the manufacturer’s guidelines and recommendations to ensure the air compressor is suitable for the intended painting or sandblasting tasks.
Proper safety measures, such as wearing protective gear and following established protocols, should always be followed when working with air compressors for painting and sandblasting applications.

What are the key components of an air compressor system?
An air compressor system consists of several key components that work together to generate and deliver compressed air. Here are the essential components:
1. Compressor Pump: The compressor pump is the heart of the air compressor system. It draws in ambient air and compresses it to a higher pressure. The pump can be reciprocating (piston-driven) or rotary (screw, vane, or scroll-driven) based on the compressor type.
2. Electric Motor or Engine: The electric motor or engine is responsible for driving the compressor pump. It provides the power necessary to operate the pump and compress the air. The motor or engine’s size and power rating depend on the compressor’s capacity and intended application.
3. Air Intake: The air intake is the opening or inlet through which ambient air enters the compressor system. It is equipped with filters to remove dust, debris, and contaminants from the incoming air, ensuring clean air supply and protecting the compressor components.
4. Compression Chamber: The compression chamber is where the actual compression of air takes place. In reciprocating compressors, it consists of cylinders, pistons, valves, and connecting rods. In rotary compressors, it comprises intermeshing screws, vanes, or scrolls that compress the air as they rotate.
5. Receiver Tank: The receiver tank, also known as an air tank, is a storage vessel that holds the compressed air. It acts as a buffer, allowing for a steady supply of compressed air during peak demand periods and reducing pressure fluctuations. The tank also helps separate moisture from the compressed air, allowing it to condense and be drained out.
6. Pressure Relief Valve: The pressure relief valve is a safety device that protects the compressor system from over-pressurization. It automatically releases excess pressure if it exceeds a predetermined limit, preventing damage to the system and ensuring safe operation.
7. Pressure Switch: The pressure switch is an electrical component that controls the operation of the compressor motor. It monitors the pressure in the system and automatically starts or stops the motor based on pre-set pressure levels. This helps maintain the desired pressure range in the receiver tank.
8. Regulator: The regulator is a device used to control and adjust the output pressure of the compressed air. It allows users to set the desired pressure level for specific applications, ensuring a consistent and safe supply of compressed air.
9. Air Outlet and Distribution System: The air outlet is the point where the compressed air is delivered from the compressor system. It is connected to a distribution system comprising pipes, hoses, fittings, and valves that carry the compressed air to the desired application points or tools.
10. Filters, Dryers, and Lubricators: Depending on the application and air quality requirements, additional components such as filters, dryers, and lubricators may be included in the system. Filters remove contaminants, dryers remove moisture from the compressed air, and lubricators provide lubrication to pneumatic tools and equipment.
These are the key components of an air compressor system. Each component plays a crucial role in the generation, storage, and delivery of compressed air for various industrial, commercial, and personal applications.
