Liquid ring compressors are used for the compression and delivery of process gases

Compression and transportation of process gas

For hydrogen, chlorine, acetylene, vinyl chloride, stupid, hydrogen sulfide, hydrogen cyanide, carbon dioxide, stupid ethylene, ethanol, acetone and other gases, the use of liquid ring compressor compression transport, the highest pressure can reach 0.8 Mpa (G), a single processing gas volume can reach 2400 cubic meters per hour.

Liquid ring compressors for process gas compression and delivery are described below. For more industrial applications, click here.

What are the advantages of liquid ring compressor?

Liquid ring compressor, small vibration, low noise and long service life, less sealing surface, safe and reliable, high efficiency, high exhaust pressure, low power consumption, the clearance between the impeller and the cone can be adjusted: avoid decline in efficiency and easy maintenance, reliable operation, the principle of liquid ring compressor impeller eccentric configuration inside the cylinder, and introduce a certain amount of water or other liquid inside the cylinder.The volume of each chamber expands and shrinks periodically with the rotation of the impeller.

The end covers on both sides of the cylinder are provided with suction and exhaust ports correspondingly. In this way, the impeller rotates once to realize the suction, compression, exhaust and possible expansion processes in each elementary volume. Gas discharge will bring out a part of the liquid, so a certain amount of new liquid must be added to the suction port. It will not only affect the service life of the motor but also consume more electricity. The system will leave a certain margin in the selection of the motor during the design. The motor speed of the liquid ring compressor is fixed, but in actual use , Sometimes it needs to run at a lower or higher speed, so it is very necessary to carry out frequency conversion transformation.

How much do you know about compressor installation

The layout of the compressor and its auxiliary equipment should meet the requirements of the manufacturer. It should be arranged near the pumping equipment. The auxiliary equipment should be close to the unit layout and single-layer layout of the compressor.When the ancillary equipment is more, it should be arranged in two layers.The installation height of the compressor should be determined according to its structural characteristics.The installation height of the compressor with inlet and outlet at the bottom shall meet the following requirements:

(1) Clearance requirements between the inlet and outlet connecting pipes and the ground;

(2) Requirements on the connection height between the inlet and outlet connecting pipes and pipes on the pipe gallery;

(3) the installation height and size requirements of the filter on the suction pipe;

(4) in order to reduce vibration should reduce the installation height of reciprocating compressor.

Compressor installation work has been completed, complete delivery documents, clean and tidy operation site, in line with the special requirements and safety regulations. Check the fastening of all parts of the compressor; Check the reliability of its positioning, anti-loosening, clearance and braking; Check the connecting parts, remove the inlet and exhaust valve, and install the safety filter valve; Check the connecting parts and locking device of motor and compressor, tighten and lock. After no abnormality. The piston compressor at this time attention should not be at all levels of the piston before and after the dead point position.

Open the cooling water system and circulating oil system (with forced ventilation and fan), and debug normally. Instantly start the motor according to the electrical operation rules, check whether there is any abnormality in the moving parts of the motor and compressor, and check whether there is any abnormality in the sound, temperature, vibration and speed of each part. It can run continuously for 8h ~ 12h without abnormal conditions. The oil pressure, bearing temperature rise and metal packing temperature should all reach the required control range.
