Problems solved by technology

The pump motor online intelligent monitoring device disclosed in this invention can detect the temperature of the pump machine during operation and monitor the current and voltage through the set sensor, current detection module, and voltage detection module, but it cannot monitor the pump group. Real-time monitoring of the running vibration of the pump body and the mechanical seal of the pump body; in addition, the device alarms through the set alarm module, but when the operator is not near the alarm, it cannot receive relevant prompts in time, let alone Send the result of pump fault diagnosis to the operator in time, reminding the operator to deal with it in time

Embodiment 1

[0052] The present embodiment 1 discloses a petrochemical pump group operation monitoring and fault diagnosis system based on an ad hoc network, the main components of which include a control cabinet 10, a portable receiving terminal, and a pump composed of multiple petrochemical pumps 1 group. Each petrochemical engine pump 1 is provided with a temperature monitoring device 2, a pump body mechanical seal monitoring device 3, a running vibration monitoring device 4, and a flow rate monitoring device for a single petrochemical engine pump 1 and a total monitoring device for the pump group. Flow monitoring device 5 for flow.

[0053] Reference attached figure 2 A plurality of petrochemical pumps 1 are neatly arranged in a row to form a pump group, a mounting base plate 21 is arranged below a row of petrochemical pumps 1 , and an organic pump seat 100 is arranged at the lower end of each petrochemical pump 1 .

Embodiment 2

[0060] Embodiment 2 discloses an improved self-organized network-based petrochemical engine pump group operation monitoring and fault diagnosis system based on Embodiment 1. The same points as those in Embodiment 1 will not be described again, and the differences are not described again. in:

[0061] In Embodiment 2, the outer surface of the pressure sensor 1082 disposed inside the nozzle 1081 is also coated with a corrosion-resistant layer, so as to protect the pressure sensor 1082 that has been in contact with oil for a long time and prolong its service life.

[0062] In addition, in Embodiment 2, sealant is also filled between the temperature probe and the jack on the temperature sensor 202, so that the pump motor 101 still has excellent water resistance after the temperature sensor 202 is installed.

[0063] The control cabinet 10 in Embodiment 2 is provided with a rectangular opening on its front side, and a cabinet door 16 is rotatably connected to the rectangular openin...

Abstract

The invention relates to the technical field of oil exploitation, and particularly discloses a petrochemical engineering machine pump group operation monitoring and fault diagnosis system based on an ad hoc network and a management method. Comprising a control cabinet, a portable receiving terminal, a machine pump group composed of a plurality of petrochemical machine pumps, temperature monitoring devices arranged on all the petrochemical machine pumps, pump body mechanical seal monitoring devices arranged on all the petrochemical machine pumps and operation vibration monitoring devices arranged on all the petrochemical machine pumps. The flow monitoring device is used for monitoring the flow of a single petrochemical machine pump and monitoring the total flow of the machine pump group; according to the design of the whole device, the intelligent degree is high, regular inspection by operators is not needed, targeted maintenance is directly carried out according to received fault diagnosis results, the labor intensity of the operators is reduced, and normal and stable operation of the petrochemical engineering machine pump group is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, and specifically discloses an operation monitoring and fault diagnosis system and a management method of a petrochemical machine pump group based on an ad hoc network. Background technique [0002] In the process manufacturing industry, especially the petrochemical industry, there are a large number of pump equipment in the factory, and a pump group is composed of multiple pumps. Once the pump fails, it usually affects production, causing waste, unstable product quality and even accidents. In the past, the monitoring of pump equipment scattered throughout the factory area was carried out by manual periodic inspection, while there were many testing parameters for the pump, such as the temperature of the pump when it was running, the vibration of the pump when it was running, and the mechanical properties of the pump body. For airtightness, etc., the existing manual periodic inspect...
