Embodiment

[0032] The specific implementation of the water pump is a cantilever single-stage single-suction double-blade centrifugal pump with a specific speed n s =111, the rated working condition is: flow Q=25.86m 3 / h, head H=2.68m, speed n=750r / min. The implementation motor is a three-phase asynchronous motor with a rated power of 7.5kW.

[0033] Build the test bench of the water pump unit: the three-phase asynchronous motor 7 of the water pump unit is equipped with a motor temperature sensor Pt1008, a motor vibration sensor HZ-892A9 and a coil induction speed sensor 11, and the three-phase asynchronous motor 7 is connected to the three-phase power line. Transformer BH-0.66-30I14; the pump body vibration sensor 25 in the XYZ three directions is installed on the test pump 1, which is INV983; the outlet hydrophone RHSA-103, the inlet hydrophone 20, and the outlet hydrophone The pressure sensor 4 is MIK-P300, the inlet pressure sensor MIK-P30019 and the outlet pressure pulsation senso...

Abstract

The invention discloses a pump unit typical health status monitoring device and method based on Internet of Things, and belongs to the technical field of intelligent diagnosis of fluid machinery Internet of Things. The pump unit typical health status monitoring device is arranged to be an erecting pump unit platform. Signal collecting sensors are arranged on the pump unit to form an Internet of Things sensing layer which is used as a collection module of data transmission, and forms an Internet of Things network layer with communication protocol; and a field monitoring platform forms an Internet of Things application layer by a touch screen / PC and compiled upper computer software. Functions performance testing, signal processing, fault diagnosing, health evaluating, database managing and remote monitoring and real time monitoring of the pump unit are achieved. Integration, automation and intellectualization of the system are high; predicative maintenance is achieved; occurrence of major accidents and economic loss are avoided, alleviated and reduced; optimal management of pump unit operation is facilitated; benefit level is improved; and pump unit overhauling and maintenance basisis provided.

Description

technical field [0001] The invention belongs to the technical field of fluid machinery Internet of Things intelligent diagnosis, and in particular relates to a typical health state monitoring method of a water pump unit based on the Internet of Things. Background technique [0002] A pump is a machine that converts the mechanical energy of the prime mover into liquid energy. It is widely used in various fields of the national economy, from industry to agriculture, civilian to military, general technical departments to cutting-edge technical departments, etc. Pumps are inseparable. The water pump unit is also the key equipment in many industrial production systems. Once a failure occurs, it will affect production at least, and cause equipment shutdown and process interruption at worst, resulting in serious economic losses and even threatening life safety. The Internet of Things is an emerging technology developed with the Internet technology in recent years. Its rapid develop...
