Abstract

The invention discloses a reciprocating compressor energy efficiency analysis system based on p-V diagram test, the system includes a hardware module and a software module, the hardware module refers to a pressure sensor, a pressure transmitter, a temperature sensor, a key phase sensor, a mutual inductance controller, data acquisition card, and software modules including data display, data processing, and data storage. This system can realize real-time measurement and analysis of the flow rate, indicated power, motor power, and efficiency of the reciprocating compressor, thereby reflecting the operation of the reciprocating compressor. situation. The beneficial results of the present invention include: the flow rate of the compressor can be obtained by measuring the p-V diagrams of the cylinders at all levels, and it is not necessary to install a flow meter on the compressor pipeline; the p-V diagrams of the cylinders at all levels can reflect the middle stages Changes in gas volume, indicated work at all levels and total indicated power; the compressor energy efficiency analysis system based on the p-V diagram test can complete real-time data processing, improve measurement efficiency, and the technology is simple 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.
