Embodiment 2

[0035] This embodiment provides an intelligent diagnosis system for on-line fault monitoring of external pump units. Further, the computer 3 in the central control room and the remote diagnosis center 2 are all equipped with a database unit, a data acquisition unit, a state monitoring unit, and a dynamic balance calculation unit. unit and analysis and diagnosis unit, and these units are special-purpose units, which belong to the prior art.

[0036]Among them, the database unit is used for data storage, which consists of a speed-up and down-speed database, a historical database and an event database, etc. It stores relevant data in different databases according to the different states of the unit for subsequent analysis. The data acquisition unit also includes a setting unit. The data acquisition unit is used for data acquisition. It can automatically identify the operating status of the unit, such as start and stop, speed up and down, and normal or abnormal status, and collect ...

Embodiment 3

[0044] This embodiment provides an intelligent diagnosis system for on-line fault monitoring of the external delivery pump unit, and the external delivery pump unit may be in a single group or in multiple groups. The intelligent diagnosis system for on-line monitoring failure of the external delivery pump unit of the present invention can simultaneously monitor a single group or multiple groups of external delivery pump units.

[0045] Further, the horizontal and vertical directions of the front and rear ends of the outbound pump 8 are equipped with a vibration detection composite sensor 9, and the vibration detection composite sensor 9 includes a vibration acceleration sensor, a temperature sensor, a rotational speed sensor and a pressure sensor integrated special composite sensor. Sensor, ATEX certified.

[0046] The sensor used in the present invention is a piezoelectric vibration measurement sensor, a temperature sensor, a hall sensor and a pressure change sensor with a bu...

Abstract

The invention provides an intelligent diagnosis system and method for online fault monitoring of an efflux pump unit. The diagnosis system comprises the efflux pump unit, an acquirer, a multi-port repeater, a local monitoring unit and a remote monitoring unit, wherein the efflux pump unit comprises a motor and an efflux pump which are connected with each other; a vibration detection composite sensor is arranged on the efflux pump and is electrically connected with the acquirer; and the acquirer, the local monitoring unit and the remote monitoring unit are electrically connected with the multi-port repeater. By the intelligent diagnosis system and method for online fault monitoring of the efflux pump unit, the problems that an efflux main pump unit of an oilfield does not have a special online fault monitoring intelligent diagnosis system, vibration exceeds the standard for a long time, the efflux main pump unit is unsafe, electric energy is wasted, and shutdown is easily caused to result in loss are solved.

Description

technical field [0001] The invention relates to the field of on-line monitoring of an outbound pump unit, in particular to an intelligent diagnosis system and method for an on-line monitoring fault of an outbound pump unit. Background technique [0002] Most of the key points of the main pump unit of Changqing Oilfield come from well-known companies all over the world. The cost is expensive, and the unit works continuously for 24 hours at a high speed for a long time. The maintenance of the equipment is extremely important and difficult. Once damaged or unexpectedly stopped, not only the direct loss is huge, but also the indirect loss caused by the shutdown of the entire line is even more inestimable. There is no monitoring for the external pump unit, and individual pump units are based on single data collection and limit protection, and there is no special online monitoring fault intelligent diagnosis system; most of the long-term vibration exceeds the standard, and a lot o...
