Motor pumps are important equipment for refining and petrochemical companies and offshore oil platforms, such as hot oil pumps for petrochemical companies, and crude oil pumps for offshore oil platforms; once these equipments fail, they may halt production processes and cause major losses.Pump impellers, bearings, and retaining rings are vulnerable components and are prone to failure.The BH7000P online monitoring and diagnosis system for key pumps can help in the early warning of failures, achieve predictive maintenance, and take measures before the failures deteriorate to reduce losses. The BH7000P key pump and pump online monitoring and diagnosis system developed has solved the important problems of online monitoring and fault diagnosis of important pumps, especially high-risk pump bearings, impellers, ring rings, gears and other vulnerable components. The enterprise avoided multiple serious accidents, realized predictive maintenance, and produced good results. The signals generated by the failure of the pump are mainly: conventional low frequency signals and high frequency shock vibration signals.Conventional low-frequency signals are expressed by speed values (mm / s), which can solve problems such as imbalance, misalignment, looseness, and eccentricity of the impeller.High-frequency shock vibration signals are expressed by acceleration (m / s2) and gIE values, which can solve bearing faults, cavitation and other faults.For this signal, Bohua Technology uses the patented technology "optimal filtering and demodulation" to analyze the "shock vibration signal" to extract the fault characteristic signal for the engineer to analyze.
· For non-bearing failures, such as imbalance, misalignment, looseness, etc., speed monitoring can be used to provide early warning. · For bearing failures, acceleration and gIE can be used for early warning. Equipment will release early warning signals before its failure, such as changes in vibration, temperature, and sound, and vibration is the most useful signal among them. Quantitative management of vibration data can solve most of the unit's failures.Equipment failure cycle is a very important factor.If the offline data collection cycle is too long, then failure information may not be captured.The BH7000P key machine pump online monitoring and diagnosis system can solve this problem and collect real-time vibration to cover the equipment failure cycle.Early warning of equipment is achieved, so that unplanned shutdowns or safety accidents of production lines can be avoided, and inspection and maintenance plans can be reasonably arranged.
