General information of structure

   Diaphragm compressor mainly consists of crankcase, connecting rod, cross-head, piston, cylinder body, cooler and its pipeline, base plate, instrumentation, electric motor etc. The compressor structure is divided into 4 types—L, Z, V and D, according to cylinder body arrangement. 
L type diaphragm compressor’s vertical and horizontal cylinders form L. (Please refer to the picture)
Z type diaphragm compressor only consists of vertical cylinders, and this structure looks like the letter “Z”. (Please refer to the picture)
V type diaphragm compressor’s left and right cylinders form V. (Please refer to the picture)
D type diaphragm compressor is the balanced opposed frame, the cylinder body number can be 2, 3 or 4. (Please refer to the picture. This is the 4 cylinders type)

Main technical data

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 diaphragms. 

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. 

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.

Gas pipes
The gas enters into compressor through inlet port to be compressed and enters into the clients’ system after cooling by the cooler.

Can Gas Air Compressors Be Used for Well Drilling?

Gas air compressors can be used for well drilling, and they are commonly employed in drilling operations. Here’s a detailed explanation:

1. Air Drilling Method:

Gas air compressors are often utilized in the air drilling method, also known as pneumatic drilling. In this drilling technique, compressed air is used to create a high-velocity airflow that carries the drill cuttings to the surface. The high-pressure air also aids in cooling the drill bit and providing additional force for efficient drilling.

2. Benefits of Gas Air Compressors:

Gas air compressors offer several advantages for well drilling:

  • Portability: Gas air compressors can be easily transported to remote drilling sites, allowing for flexibility in well location.
  • Power: Gas air compressors provide high-pressure air output, which is essential for effective drilling in various geological formations.
  • Cost-Effectiveness: Gas air compressors can be more cost-effective compared to other drilling methods, as they eliminate the need for drilling mud and associated disposal costs.
  • Environmental Considerations: Air drilling with gas compressors produces minimal waste and does not require the use of potentially harmful drilling fluids, making it an environmentally friendly option.

3. Compressor Selection:

When selecting a gas air compressor for well drilling, several factors should be considered:

  • Pressure and Flow Requirements: Evaluate the pressure and flow requirements of the drilling operation to ensure that the gas air compressor can deliver the necessary air output.
  • Compressor Size and Power: Choose a compressor with adequate size and power output to match the drilling demands. Factors such as borehole depth, drill bit type, and drilling speed will influence the compressor’s power requirements.
  • Portability: Consider the portability features of the gas air compressor, such as its weight, dimensions, and mobility options, to facilitate transportation to drilling sites.

4. Safety Considerations:

It is essential to follow safety guidelines when using gas air compressors for well drilling. These may include proper ventilation to prevent the accumulation of exhaust fumes, adherence to equipment operating limits, and the use of personal protective equipment (PPE) for drilling personnel.

5. Other Considerations:

While gas air compressors are commonly used for well drilling, it is worth noting that the suitability of a gas air compressor for a specific drilling project depends on various factors such as geological conditions, well depth, and drilling objectives. It is recommended to consult with drilling experts and professionals to determine the most suitable drilling method and equipment for a particular project.

In summary, gas air compressors can be effectively used for well drilling, particularly in the air drilling method. They offer portability, power, cost-effectiveness, and environmental advantages. Proper selection, considering pressure and flow requirements, as well as safety precautions, is crucial to ensure successful and safe drilling operations.

What Is the Role of Air Receivers in Gas Air Compressor Systems?

Air receivers play a crucial role in gas air compressor systems by serving as storage tanks for compressed air. Here’s a detailed explanation:

1. Storage and Stabilization:

The primary function of an air receiver is to store compressed air generated by the gas air compressor. As the compressor produces compressed air, the air receiver collects and stores it. This storage capacity helps meet fluctuating demand in compressed air usage, providing a buffer between the compressor and the system’s air consumption.

By storing compressed air, the air receiver helps stabilize the supply to the system, reducing pressure fluctuations and ensuring a consistent and reliable flow of compressed air. This is particularly important in applications where the demand for compressed air may vary or experience peaks and valleys.

2. Pressure Regulation:

Another role of the air receiver is to assist in pressure regulation within the gas air compressor system. As compressed air enters the receiver, the pressure inside increases. When the pressure reaches a predetermined upper limit, typically set by a pressure switch or regulator, the compressor stops supplying air, and the excess air is stored in the receiver.

Conversely, when the pressure in the system drops below a certain lower limit, the pressure switch or regulator signals the compressor to start, replenishing the compressed air in the receiver and maintaining the desired pressure level. This cycling of the compressor based on pressure levels helps regulate and control the overall system pressure.

3. Condensate Separation:

During the compression process, moisture or condensate can form in the compressed air due to the cooling effect. The air receiver acts as a reservoir that allows the condensate to settle at the bottom, away from the outlet. The receiver often includes a drain valve at the bottom to facilitate the removal of accumulated condensate, preventing it from reaching downstream equipment and causing potential damage or performance issues.

4. Energy Efficiency:

Air receivers contribute to energy efficiency in gas air compressor systems. They help optimize the operation of the compressor by reducing the occurrence of short-cycling, which refers to frequent on-off cycling of the compressor due to rapid pressure changes. Short-cycling can cause excessive wear on the compressor and reduce its overall efficiency.

The presence of an air receiver allows the compressor to operate in longer and more efficient cycles. The compressor runs until the receiver reaches the upper pressure limit, ensuring a more stable and energy-efficient operation.

5. Air Quality Improvement:

Depending on the design, air receivers can also aid in improving air quality in the compressed air system. They provide a space for the compressed air to cool down, allowing moisture and some contaminants to condense and separate from the air. This can be further enhanced with the use of additional filtration and drying equipment installed downstream of the receiver.

In summary, air receivers play a vital role in gas air compressor systems by providing storage capacity, stabilizing compressed air supply, regulating system pressure, separating condensate, improving energy efficiency, and contributing to air quality control. They are an integral component in ensuring the reliable and efficient operation of compressed air systems across various industries and applications.

Are There Different Types of Gas Air Compressors Available?

Yes, there are different types of gas air compressors available, each designed to suit specific applications and requirements. These different types vary in terms of design, power source, configuration, and intended use. Here’s a detailed explanation of the various types of gas air compressors:

1. Reciprocating Gas Air Compressors:

Reciprocating gas air compressors, also known as piston compressors, use a reciprocating motion of one or more pistons to compress the air. These compressors are commonly used for small to medium-scale applications and are available in both single-stage and two-stage configurations. Single-stage compressors compress the air in a single stroke, while two-stage compressors use an additional cylinder for further compression, resulting in higher pressures.

2. Rotary Screw Gas Air Compressors:

Rotary screw gas air compressors utilize two interlocking helical screws to compress the air. These compressors are known for their continuous and efficient operation, making them suitable for demanding industrial applications. They are often used in industries such as manufacturing, construction, and automotive where a constant supply of compressed air is required.

3. Rotary Vane Gas Air Compressors:

Rotary vane gas air compressors use a rotor with sliding vanes to compress the air. As the rotor rotates, the vanes slide in and out, creating compression chambers that compress the air. These compressors are compact, reliable, and often used for smaller-scale applications or in situations where space is limited.

4. Centrifugal Gas Air Compressors:

Centrifugal gas air compressors operate by accelerating the air using a high-speed impeller. The accelerated air is then redirected into a diffuser, which converts the velocity energy into pressure energy. These compressors are commonly used for large-scale applications requiring high volumes of compressed air, such as in power plants, refineries, or chemical processing industries.

5. Oil-Free Gas Air Compressors:

Oil-free gas air compressors are designed to provide clean, oil-free compressed air. They feature special sealing mechanisms and materials to prevent oil contamination in the compressed air. These compressors are commonly used in industries where oil-free air is essential, such as food and beverage processing, pharmaceuticals, electronics manufacturing, and painting applications.

6. Portable Gas Air Compressors:

Portable gas air compressors are specifically designed for mobility and ease of transportation. These compressors often feature wheels, handles, or trailers for convenient movement. They are commonly used in construction sites, remote job locations, outdoor events, or other situations where compressed air is needed at different locations.

7. High-Pressure Gas Air Compressors:

High-pressure gas air compressors are designed to generate compressed air at elevated pressures. These compressors are used in applications that require air pressure higher than the standard range, such as in diving operations, breathing air systems, or specialized industrial processes.

8. Biogas Air Compressors:

Biogas air compressors are specifically designed to compress biogas, which is generated from the decomposition of organic matter. These compressors are used in biogas production facilities, landfills, wastewater treatment plants, or agricultural operations where biogas is produced and utilized as an energy source.

These are just a few examples of the different types of gas air compressors available. Each type has its own advantages and is suitable for specific applications based on factors such as required airflow, pressure, mobility, oil-free operation, and environmental considerations. It’s important to choose the appropriate type of gas air compressor based on the specific needs of the application to ensure optimal performance and efficiency.
