Air compressor K-1500, 1700 (analog) 87,000 nm³/hour single-shaft

The 4TYD135 model air compressor is a type of compressor equipment manufactured as an analog to the more common K-1500 and K-1700 models in Russia. It is identical to them in technical specifications but superior in energy efficiency.

Design Structure

Similar to the K-1500 air compressor, the presented model consists of the following elements:

The compressor consists of a housing with a drive shaft installed inside, onto which working impellers with blades are pressed. Systems responsible for control command transmission and regulation, lubrication supply and distribution, performance monitoring, voltage surge protection, and fault signaling are used to connect these components.

Optionally, each unit can be equipped with an automatic monitoring and analysis system. Digital control provides instant access to any equipment operating parameters with the ability to adjust them.

Operating Principle

The operating principle of the K-1500 air compressor is based on dynamic compression of the air flow entering the internal cavity. Compression occurs through continuous rotation of working impellers that impart centrifugal acceleration to the air. Moving sequentially between the unit stages, air is compressed to required pressure parameters and delivered through the outlet port.

Air rotating under the action of working impeller blades generates heat, which is absorbed by gas-water heat exchangers installed between compression stages. Compressor capacity can be regulated according to demand. For this purpose, an inlet guide vane (IGV) is installed on the inlet port, whose rotation increases or decreases the flow cross-section.

Applications

The K-1700 compressor and its analogs are used in various industrial production sectors. Their application is in demand where technological processes require regular supply of compressed air. Such enterprises include metallurgical plants and chemical production facilities.

At RusGazCryo company, you can order supplies of Parma K-1500 air compressor analogs from a manufacturer with thirty years of industry experience. Each equipment unit is supplied with necessary manufacturer documentation, including warranty. In addition to the products themselves, the range includes spare parts for the Parma K1500 compressor.

Air compressor K-3000 (analog) 180,000 nm³/hour single-shaft

The main purpose of model 4TYD150 is atmospheric air compression with subsequent supply to separation units. Installations analogous to the K-3000 compressor are widely used in chemical, metallurgical, and other industries where compressed gas is necessary for technological needs.

Features

The productivity of the K-3000 compressor analog is 180,000 nm³/hour. This is a powerful four-stage installation with steam turbine drive. The installation is also equipped with three intermediate and one final cooler. No gearbox is present.

Manufacturer RusGazKrio develops compressor equipment taking into account consumer needs and operating conditions. More than 70 years of experience in designing and manufacturing centrifugal air compressors allows us to create powerful and reliable equipment with high productivity and low failure rates.

Centrifugal Air Compressor Advantages

Model 4TYD150 is a high-quality, energy-efficient analog of the K-3000 air compressor manufactured by REP Holding, widely used in metallurgical and chemical industries. Compared to the original, it has numerous advantages:

  1. The inlet guide vane, responsible for directing gas flow movement, enables productivity regulation while minimizing losses.
  2. Heat exchangers have low resistance to air flow, guaranteeing high cooling efficiency.
  3. The air compression process in the K-3000 analog approaches isothermal due to staged, three-step compression and the presence of three interstage coolers.
  4. High installation productivity was achieved through joint work of advanced international teams.

Another advantage of equipment supplied by RusGazKrio is the possibility of equipping centrifugal air compressors with the MAPRO system, responsible for analysis, monitoring, and prediction of such rotary installations.

MAPRO Advantages

The system was created by RusGazKrio company for digitizing rotary equipment installed in large workshops of industrial productions. Its main advantages are:

Various equipment for modernization and equipping compressor workshops, including K-3000-63 and oxygen booster compressors, can be purchased from RusGazKrio using a special form on the website.

Oxygen compressor 3CKK-100/3.5M (equivalent) 6,000 nm³/hour up to 1 MPa

The main application of centrifugal compressors, including the 3TYS72 model, is oxygen compression. The equipment is designed for operation at a working pressure of no more than 1 MPa and has a capacity of 6000 nm3/hour. The equipment is in demand at metallurgical plants, in the synthesis of chemical compounds, and in other processes where compressed oxygen is required.

What makes our equipment special

RusGazCryo offers a wide range of compressor equipment. It is designed specifically for oxygen compression using Hitachi technologies. We work with a reliable supplier that has been designing and manufacturing compressor units for oxygen processing for over 70 years.

To ensure that the equipment is completely safe to operate, the following technical solutions have been implemented:

  1. The inside of the device housing is coated with copper spray.
  2. The device includes anti-pump protection as an addition to the security system.
  3. Gas seals are used in differential multi-channel systems, minimizing the risk of gas leakage and environmental contamination.
  4. During compression, the gas temperature is constantly monitored.
  5. Labyrinth seals are used in a multi-port type, which guarantees safety and eliminates gas leakage.

Additional features

Centrifugal compressors for oxygen are also manufactured by Kazancompressormash. However, when comparing this manufacturer’s model 3CKK-100/3.5M with the 3TYS72 model, the equipment offered by RusGazCryo is more energy efficient. In addition, it is compatible with the MAPRO system. This is a comprehensive solution that allows you to monitor and analyze data and use it to make predictions about the operation of rotary equipment.

What does the MAPRO system offer?

MAPRO was created by RusGazCryo to enable large production facilities to digitize data from rotary equipment.
