Reciprocating compressor energy efficiency analysis system based on P-V diagram test

Abstract

The invention discloses a reciprocating compressor energy efficiency analysis system based on a p-V diagram test. The system comprises a hardware module and a software module, the hardware module comprises a pressure sensor, a pressure transmitter, a temperature sensor, a key phase sensor, a mutual inductor and a data acquisition card, the software module comprises data display, data processing and data storage. The system can achieve real-time measurement and analysis of the flow rate, indicated power, motor power and efficiency of a reciprocating compressor, so that the operation situation of the reciprocating compressor is reflected. The system has the beneficial effects that the compressor flow can be obtained through p-V diagrams of measured cylinders at each level without the need ofinstalling a flowmeter on a compressor pipeline; the p-V diagrams of the measured cylinders at each level can reflect the change of air volume at all levels, the indicated power at all levels and thetotal indicated power intermediately; the compressor energy efficiency analysis system based on the p-V diagram test can complete the real-time data processing, the measurement efficiency is improved, and the technology is simple and convenient, and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to an energy efficiency analysis system of a reciprocating compressor. Background technique [0002] Large-scale reciprocating compressors are key equipment in industries such as chemical synthesis and natural gas gathering and transportation, and are also major energy-consuming equipment. With the expansion of production scale, the number and specifications of reciprocating compressors are expanding, and the power of many compressors is at the megawatt level. Judging from the current usage of compressors, many compressors have the problem of imprecise energy consumption management. The energy consumption status of the compressors is not clear, and they may even run under low-efficiency conditions for a long time, resulting in huge energy consumption and reducing the cost of enterprises. overall benefit. At present, the country is entering the 14th five-year period...

Problems solved by technology

However, for power consumption and flow measurement, most of the measuring devices currently on the market must be installed on the main engine and pipelines. Due to the lack of on-site installation conditions or the safety regulations do not allow it, the use of such measuring devices has great limitations.
