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.

How Does an Oil-Free Air Compressor Work?
An oil-free air compressor, also known as an oilless air compressor, operates using alternative methods to achieve compression without the need for lubricating oil. These compressors employ various techniques to deliver clean, oil-free compressed air. Here’s a detailed explanation of how an oil-free air compressor works:
1. Dry Compression:
In oil-free air compressors, the compression chamber is designed to operate without any oil present. The compression process starts with the intake stroke, where ambient air is drawn into the compressor through an inlet valve. The air is then compressed in the compression chamber without any oil lubrication.
2. Friction Reduction:
Since there is no oil in the compression chamber, special measures are taken to reduce friction and wear between the moving parts. These measures include the use of specialized materials, coatings, and surface treatments on the compressor components. These friction-reducing techniques minimize the need for lubrication and allow for efficient compression.
3. Piston Rings and Seals:
Oil-free compressors utilize advanced piston rings and seals to provide effective sealing without the need for oil lubrication. These rings and seals are designed to reduce internal leakage and ensure efficient compression. They help maintain the compression efficiency by minimizing air leakage during the compression process.
4. Cooling Mechanisms:
Oil-free air compressors often incorporate cooling mechanisms to dissipate the heat generated during compression. This helps prevent overheating and ensures the compressor operates within acceptable temperature limits. Common cooling methods include water cooling and air cooling. Water-cooled compressors use a water jacket or a separate cooling circuit to remove heat, while air-cooled compressors rely on fans and heat sinks to cool the compressor.
5. Filtration:
