BH9000 Machinery Protection System (MPS)
The BH9000 Machinery Protection System (MPS) features condition monitoring, fault diagnosis, and vibration protection in one system, making it suitable for monitoring and protection of critical machinery. The system continuously monitors vibration and process parameters, such as radial vibration, case vibration, axial displacement, key phase, speed, eccentricity, differential expansion, temperature, and pressure etc. It provides reliable protection against catastrophic equipment failures and offers comprehensive analytical tools for predicting and diagnosing mechanical faults.
System Functions
The BH9000 can continuously and synchronously collect, analyze and store all kinds of input signals, and can automatically identify the running status of the machine, such as startup/shutdown, speed up/down, and normal or abnormal status, and collect data according to the running status.
When there is an abnormality in the machine, the system drives relays output according to the logical operation which is set inside system to shutdown machine in order to avoid greater losses.
Each input channel corresponds to a 4-20 mA output, which converts the sensor measurement value into a current signal for PLC, DCS or others.
Records alarm events and system events. The list of events allows you to recognize the status of the BH9000 at the moment of the event.
BH9000 has professional vibration analysis tools, including Trend, Waveform, Spectrum, Phase, Envelope, Shaft Orbit, Shaft Position, Waterfall, Bode, Polar, Cascade and so on.
It is possible to diagnose mechanical faults such as imbalance, misalignment, component dislodgement, surge, flow excitation, gear and bearing failure, etc., based on professional analysis tools.
Data Collector
BH7000 Data Collector, a key hardware, is designed for condition monitoring system. The modularization feature makes BH7000 a universal platform which can be applied in any scenario. By combining different modules, BH7000 can be applied on various machines.

Stepless Capacity Control System (BHSCCS for short) is designed for reciprocating compressors and utilizes a partial-stroke, top-opening inlet valve. The system adopts a hydraulic system to control the mechanical unloader to press open the suction valve, control the compressor discharge volume by controlling the volume of air returning to the suction pipeline during the compression process, thus controlling the load of the unit to meet the demands of the production process on site, eliminating the return loss, effectively reducing the operating current of the unit under low load condition, and realizing the high efficiency and green operation of the unit.
