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.

6. Environmental Considerations:
Oil-free air compressors are environmentally friendly due to the absence of oil. They eliminate the risk of oil spills or leaks that can harm the environment. Furthermore, oil-free compressors may require less energy consumption compared to oil-lubricated compressors, contributing to energy efficiency and reduced carbon footprint.
7. Lower Initial Cost:
In general, oil-free compressors tend to have a lower initial cost compared to oil-lubricated compressors. This can be advantageous for applications with budget constraints or when the specific requirements of the application align with the capabilities of oil-free compressors.
It’s important to note that oil-free air compressors may have certain limitations compared to oil-lubricated compressors. They may have lower maximum operating pressures and higher operating temperatures. Additionally, the absence of oil lubrication may result in slightly reduced efficiency and increased wear on certain components over time.
By considering these advantages, users can determine whether oil-free air compressors are suitable for their specific application and requirements.
