Description

DEVICE FOR MEASURING THE REAL-TIME PERFORMANCE OFA PUMP
TECHNICAL FIELD OF THE INVENTION
This invention relates to a device and a system for measuring real-time performance data for pumps and in particular vacuum pumps.
BACKGROUND ART
In a production environment utilising vacuum pumps as an integral part of a system, performance needs to be monitored to ensure maximum productivity. Typically a performance test would require disconnecting and isolating the suction port of the pump and fitting a range of beam nozzles of varying inlet diameters and recording the resultant pressure and temperature conditions. This data is used to calculate the respective duty points of the pump, thus enabling a performance curve to be plotted for it. The process is done manually, typically every 6 - 12 months and involves disconnecting the pump from the line. Another alternative method is to measure vibration of the pump but this method is not widely used.
The above methods have the disadvantage that they do not operate in-line with the factory system and hence cannot provide real-time performance information. Real-time performance information would be an invaluable asset to production managers in maintaining optimum productivity of their lines. Any performance degradation would be immediately visible in the output allowing faster response to issues on the production line. Tracking long term performance degradation due to wear and tear on pumps, seals bearings etc becomes easier and preventative maintenance can be planned/ undertaken with less disruption to production outputs.
It is therefore an object of this invention to provide a device and method for measuring pump performance data which works in-line with the factory system and monitors the capacity at the suction portion of the pump to calculate the pump's realtime performance characteristics. DISCLOSURE OF THE INVENTION
According to the invention, a device for measuring the real-time performance of a pump comprises a spool piece attachable to the suction port of a pump, the spool piece including one or more spaced apart sockets for receiving electronic sensor devices for measurement of one or more of temperature, pressure and flow velocity.
In the preferred form the sensors deliver a mA output signal.
Also in the preferred form, the number of sockets corresponds to the number of sensors required to measure the pump performance, the spacing of the sockets depending on the length and diameter of the spool.
Also in the preferred form of the invention, the spool piece includes a snifter vacuum breaking valve at the inlet end of the spool piece and a non-return valve at the outlet side thereof. The snifter valve is preferably a spring-loaded relief valve and is used to bleed air into the pump when the duty point approaches the zone of cavitation (at the respective water temperature and ambient pressure).
The non return valve is a spring loaded disc valve which is positioned on the suction port of the pump. This serves to automatically isolate the system condition from the vacuum pump, when the vacuum pump is stopped, preventing air being drawn through the pump from the atmosphere.
In experimentation, it was noted by the Applicant, that the optimum functioning of the temperature sensor was not affected by its position in the spool piece. Accordingly, the temperature sensor is preferably located in the socket closest to the inlet end of the spool piece. The pressure sensor requires no probe rod and would therefore have less turbulence effect on through flow (and in particular on the velocity sensor located behind it) and is accordingly located in the middle. Testing showed that air flow was most laminar and had the least turbulence toward the rear of the spool piece and accordingly, in the preferred form, the velocity sensor is located in the socket furtherest from the inlet end of the spool piece. The tips of the velocity and temperature probes are preferably located in the middle of the spool piece when viewed in cross-section.
According to a second aspect of the invention, a system for measuring pump performance makes use of a spool piece of the invention, the sensors thereof being connected to a data acquisition system, capable of interpreting the mA output signal from the sensors and outputting it in metric units.
The metric units are as follows:
Air velocity output - metres per second
Temperature - degrees Celsius
Pressure - bar
The data acquisition system may in its simplest form comprise a USB data acquisition card (DAQ) to interpret the signals and a software program to log the date from each channel into a file.
In one form, the data acquisition system may comprise an adaptor including an electronic circuit adapted to convert the output to serial RS-232 which is convenient for industrial installations and long cable segment lengths. The data may be read by a software application running on a computer located in the vicinity of the sensors. The computer may be provided with an internet connection by means of which the software transmits the raw data to a web service or to a web page running on a web server at a remote location. The raw data on the web service or web page is preferably cleaned and the volumetric flow (capacity) is calculated for each measurement.
The static data necessary for the calculations may be stored in tables inside the database. The raw data and calculated values will then be inserted into staging tables in a database management system, together with fields that contain keys to the client and pump numbers. The database will consists of tables containing the raw data, client and pump details, and other tables containing information relevant to the system.
In another form of the invention the data acquisition system comprises a mobile unit such as a trolley or the like. According to a third aspect of the invention a method of measuring real-time pump performance includes the steps of obtaining in-line measurements of temperature, pressure and flow velocity (raw data), collating the raw data by means of a data acquisition system, reading the data using a computer software application, transmitting the raw data to a web service and/or a web page at a remote location, cleaning the data and calculating the volumetric flow (capacity) for each measurement.
In the preferred form, static data required for each calculation is drawn from tables stored within the web server or web page database. Raw data calculated values may be inserted into staging tables in a database management system, together with fields which contain keys to the client and pump numbers, and other tables containing information relevant to the system.
This system can be applied to any pump technology, but it is with vacuum pumps that this system is most revolutionary in terms of being a new way to achieve a long standing objective of measuring pump capacity. The most appealing benefits in the business sense are the real time reports. Planned and Scheduled maintenance are far less disruptive to a production cycles than a breakdown or unplanned shut. Spotting any performance degradation early on allows management to analyse and rectify the problem before its starts affecting their output.
The information is stored in a database and is available live from any device with an internet connection. This online design allows the data to be available to a wide range of platforms that are not geographically limited. The system can be set to inform production manager via electronic means such as email and sms, or can output any number of visible and audible alarms on the factory floor or in control rooms in the event of any degradation of performance out of an acceptable range.
