What is Hydraulic Gas Compressor?
A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Compression of a gas naturally increases its temperature. When the gas is air, the machine is called an air compressor.
Benefits of Hydraulic Gas Compressor
Lower energy costs: With electricity costs consistently surging higher, hydraulic gas compressor are a smart way to save on electricity costs. These air compressors are powered by natural gas, which greatly reduces the electricity needed and, therefore, can save a lot of money for a facility that uses air compressors.
Versatile for remote work: With a hydraulic gas compressor, there's no need to be constantly attached to an electrical power source, so you can use your air compressor on remote job sites and other areas where finding electricity may be a problem. They can also move across job sites, providing compressed air in different locations without needing to be stationary and plugged in.
High efficiency: Air compressors powered by gas offer a high-efficiency workload, even without a full tank. These compressors are heavy duty and work for various applications.
Better heat recovery: Many gas air compressors can make use of the excess heat recovered from the cooling jacket as well as the gas exhaust. This makes hydraulic gas compressor much more efficient than other types.
Types of Hydraulic Gas Compressor
Positive displacement compressors
Reciprocating compressors: These compressors use a piston and cylinder mechanism to compress the gas. Based on their compression method, they can be further classified into single-acting and double-acting reciprocating compressors.
Rotary screw compressors: These compressors employ interlocking helical screws to compress the gas.
Rotary vane compressors: These compressors use rotating vanes to compress a gas, ensuring a continuous flow.
Dynamic compressors
Centrifugal compressors: Centrifugal compressors utilize rotating impellers to impart velocity to gas, which is then converted into pressure. They can be axial flow or radial flow compressors.
Axial compressors: Axial compressors feature a series of rotating and stationary blades to compress gas continuously.
Diagonal compressors: These compressors combine the features of both centrifugal and axial compressors, offering a balance between pressure ratio and flow rate.
Hybrid compressors
Scroll compressors: These compressors use orbiting scroll-shaped plates to compress a gas, making them compact and efficient.
Liquid ring compressors: Liquid ring compressors utilize a liquid ring to create compression, which is ideal for handling wet gases.
Scroll-screw compressors: These compressors combine the benefits of both scroll and screw compressors, delivering enhanced efficiency and reliability.
Application of Hydraulic Gas Compressor
In pipeline transport of purified natural gas to move the gas from the production site to the consumer.
In petroleum refineries, natural gas processing plants, petrochemical and chemical plants, and similar large industrial plants for compressing intermediate and end product gases.
In refrigeration and air conditioner equipment to move heat from one place to another in refrigerant cycles (see Vapor-compression refrigeration).
In gas turbine systems to compress the intake combustion air.
In storing purified or manufactured gases in small volume, high pressure cylinders for medical, welding and other uses.
In various industrial, manufacturing and building processes to power all types of pneumatic tools.
In pressurized aircraft to provide a breathable atmosphere of higher than ambient pressure.
In some types of jet engines (such as turbojets and turbofans) to provide the air required for combustion of the engine fuel. The power to drive the combustion air compressor comes from the jet's own turbines.

In miscellaneous uses such as providing compressed air for filling pneumatic tires.
Process of Hydraulic Gas Compressor
Compressor package installation
Manufacturers of large reciprocating compressors have clear guidelines for how the equipment should be installed and maintained for best performance. And with laser alignment equipment, you can perform 90% of the measurements that are required:
A: Measure flatness and level of foundation and compressor and driver sole plates.
● Check soft foot of compressor and driver.
● Perform shaft alignment between driver and compressor.
● Perform bore alignment verification:
● Measure flatness and level of the top plane of the compressor frame.
● Check main bearing and connecting rod bearing clearance.
● Check connecting rod and crankshaft thrust clearance.
● Measure engine thrust.
● Perform dynamic measurement to check thermal expansion and pipe strain.
● And more.
Foundation flatness and level
For any machine that contains rotating parts, it is essential that the foundation on which the machine is placed is completely flat and level.
Soft foot check and shaft alignment
Soft foot is a condition that must be avoided, since it can cause great damage to bearings, shafts, and other parts of the machine. The occurrence of soft foot can be detected within the Shaft alignment program.
Main bearing bore alignment
The mounting surface of the top cover on a compressor frame is precision-manufactured to be flat and aligned with the main bearing bores and the bottom of the compressor feet. To ensure the best running conditions for the compressor main bearing and crank shaft, it is important to measure this surface, so it is aligned within the recommended tolerances.
Checking of clearance and thrust
Bearing clearance refers to the space between the shaft and the bearing surface which is filled with lubricating oil. It's important to keep this within tolerance to avoid bearing failure. On the compressor, we need to measure the main bearing clearance and the connecting rod bearing clearance. The clearance space is measured by lifting the shaft/rod and measuring the gap.
We also need to check that there is no excessive thrust in the crankshaft or connecting rod, which could cause serious damage to bearings, pistons, or other components. We do this by measuring the horizontal movement. We mount the detectors, set them to zero and then by using a prey bar, we force the crank shaft to move axially to its end. Then we record the travel which is our clearance. Engine thrust is measured in the same way.
Measure machine movement
A dynamic measurement is conducted while the machine is running, to check whether there are any external forces that can have a negative effect on machine performance.
How to Maintain Hydraulic Gas Compressor
Read the operation manual
Some of the most common problems with an gas compressor can be easily fixed with the help of the operation manual. Although this sounds very easy, many gas compressor owners forget about this manual completely and cause danger in terms of even the most easily solved problems.
Tighten the nuts and bolts
Because an gas compressor is used daily, it is inevitable that some nuts and bolts will loosen with long term use. As a result, as the machine vibrates, the parts that constitutes the machine also move. It is useful to check and tighten the loose screws and the fasteners at regular intervals.
Clean the suction valves
For an gas compressor to work in full capacity, it needs to have the fresh air inlet holes. When you continue to use the compressor for weeks, dust particles and other air-related elements are sucked into the ventilation holes.
Independently of the working environment, clean the suction valves at least once every three months to ensure the purity of the air released.
Check the hoses
Among all parts of an gas compressor assembly, hoses are the most vulnerable ones. As the component that transfers compressed air between the machine and a certain endpoint, hoses need to be strong and tight, but also flexible. Therefore, hoses bear a lot of responsibility and can easily become strained as time goes by.
Check the hoses regularly so that the compressor does not delay due to the worn hoses. If you see wrinkles or signs of wear, replace the hose with a new one. If this is ignored, a worn hose may render your gas compressor inefficient.
Replace the air filter
The function of the filter is to collect all the dust that seeps into the compressed gas and will deteriorate the quality of its operations, however, as the filter fills up, the compressor performance decreases and begins to lose its function. Therefore, it is very important to replace the air filter annually.
Drain the condensate from the tanks
As with filters, the moisture tank will fill up eventually. If the tank is very full, water may mix into air again and move to the other parts of the system. Even worse, the water may perish and send odours and pollution through the compressed air system. Therefore, it is very important to drain the moisture tank regularly.
Clean the compressor fuel tank
Fuel-driven gas compressors require some extra annual maintenance. The problem here relates to the fuel particles that can accumulate inside the tank and become toxic as time goes by. Fuel that is the lifeblood of the machine may eventually become toxic if the tank itself is not cleaned once a year. To clean the fuel tank, drain the remaining gas and then apply wet-dry vacuum inside the tank. Depending on the design of the tank, it may be necessary to replace the filter to clean the remaining debris.
Change oil
Not all gas compressors use oil, however they need an oil change just like a car does. To ensure the various engine parts moving trouble-free, the oil itself needs to remain fresh and full.
At high operating temperatures, the oil may lose its viscosity and ultimately not provide suitable lubrication to the various inner components of an gas compressor. This lack of lubrication may cause stress and wear along the moving metal parts and may fail very early periods. Similarly, colder operating environments may cause oil sludge, especially if the oil gets damp.
A natural gas compressor station is a vital component of a gas processing facility. Typically located every 60-100 km along a pipeline, compression stations ensure methane (natural gas) can move efficiently through pipelines to end-users. In addition, compressing cooled methane is the safest way to transport it.
The first step of natural gas compression is the scrubbing process. Scrubbing removes solid, liquid and gaseous impurities from the methane before it becomes pressurized.
The purified gas then travels through yard piping to the compression stations, where computers monitor and regulate the gas flow and increase its pressure by reducing its volume. Once full operational pressure is achieved, the natural gas is released into the pipeline.
Compress Gas
Axial: Multiple-blade rotor imparts axial velocity that is converted to pressure; with very high flow rates.
Blower: Dynamic head is imparted to the gas by means of high-speed impellers rotating in a confining case. Blowers are available in axial flow, radial, or centrifugal configurations.
Centrifugal: High-speed impeller produces radial airflow; velocity converted to pressure energy.
Diaphragm: Diaphragm oscillation driven by rod; no sliding seals or parts.
Linear: Linear compressors have no sliding parts; compression is generated with electromagnetic oscillation. This type of compressor is clean and quiet.
Reciprocating piston: Piston mechanically reduces air volume inside cylinder.
Rotary lobe: Gas is moved by the positive displacement of two rotating lobes confined in an eccentric cylinder.
Rotary screw: Rotating helical screw compresses air prior to discharge; provides even flow at relatively low pressures. Wet or dry screw types are utilized.
