HCDEC Контролируемое ПК устройство изучения двухступенчатого компрессора

The Computer Controlled Two-Stage Compressor Test Unit, "HCDEC", works with compressed air and presents as a principal device a compression bench with two pistons, low and high pressure.

This unit presents four circuits or work dispositions which allow to study the different compression situations.

In the four selectable circuits that the unit presents, it can be identified the similar first stage where the air enters by aspiration of the compressor piston. In this first stage the air pass through a priming vessel where the condensates are collected, the air pass across the flow sensor, temperature sensor and pressure sensor which collect the information through the computer. The first stage presents a pressure gauge and air filter too.

After this first stage, the unit presents different compression situations which offer the data of each compression points through three different temperature and pressure sensors. The unit presents a concentric tubes heat exchanger which cools down the compressed air stream with refrigeration water, two temperature sensors collect the data and allow to do the heat balance calculation in the device, and study the influence of this device over this type of process.

The unit allows for studying different compression situations:

a) Compression in one stage – low pressure piston.

b) Compression in one stage – high pressure piston.

c) Two stages without intercooling.

d) Two stages with intercooling.

All of the circuits present the respective safety systems, relief valves, check valve such as two safety pressure switch.

The compression circuits are selected through the computer. The unit allows the representation of the instantaneous compressed cycle and the measurement of: the power consumed by the compressor, the data of pressure and temperature in every point of the compression and the operation time required to perform the compression.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
