Abstract

The present invention is designed to transmit to a host computer a result of judgement of operation of each steam trap and measurement of steam leakage, to automatically totalize and analyze the result of measurements, and to predict the time to repair or replace.

Description

Steam trap operation judging device
The present invention relates to differentiate the steam trap operation judging device of steam trap working condition, i.e. steam trap leaked steam whether is perhaps measured the leakage rate of steam.
Steam trap is installed in steam line or uses on the device of steam, and only standard is emitted the water of collecting automatically and do not let off steam.Because fuel price rises, need the leakage of more and more stricter supervision steam.Leaked steam has not become the prerequisite of selecting steam trap for use now.Steam line after installing, is checked strictly that the steam trap of leaked steam must be repaired or change.
Developed now and the actual leak detector that has used the steam trap of various ways.
For example, on the pipeline of steam trap outlet end, insepction window is set, observing fluid state wherein, and is used for thermometer and vibrometer with the surface temperature of measuring steam trap and the mobile sound of fluid.
No matter above-mentioned which kind of situation only to accomplish the qualitative observation to the leak condition of steam trap, can not be accomplished the quantitative measurment to leaking.So, the degree of differentiate leaking also fibrous root according to people's sensation.
Therefore, the applicant has invented simple steam trap leak detector.
A kind of in the detector is that Japanese patent application No. 61-57499 proposes.This invention is according to determining steam leakage with vapor pressure as the vibration and the mutual relation of steam leakage of parameter.Steam leakage is equipped with the measured in advance and storage of detector of vibration transducer and temperature transducer by an inside.This detector is contained on the outer surface of block steam and drain water valve shell.
Another device that Japanese patent application No. 61-56521 proposes is arranged between steam supply side and the steam trap, and decides steam leakage by the relation between the horizontal plane of the steam flow by nozzle and its primary side.
Said apparatus can be differentiated the working condition of each steam trap and measure steam leakage, but work is differentiated and a series of preparatory works of the measurement result of leakage rate, the accumulating totals and the analysis of accumulative total of leaking and the leakage represented with amount or excretion rate all need the manual operation of trouble.In addition, repair or change the steam trap that leaks vapour and will after detection, just can carry out, therefore can not make steam trap obtain predetermined maintenance.
Therefore, technical target of the present invention be can add up automatically and analysis detecting data and can predict the repairing and the replacement cycle.
The technological means that addresses the above problem that the present invention discloses is can differentiate the working condition of each steam trap and pass through the detection of steam leakage detector and the storage steam leakage, the data of above-mentioned storage are sent to declare in the host computer, this machine writes down and shows the work differentiation result and the leakage rate of each steam trap, accumulative total and the leakage of analyzing the total leakage rate of all steam traps and representing, and the time dependent situation of each steam trap with amount and excretion rate.
The function of above-mentioned technique device will be discussed below.
The work differentiation of each steam trap and the mensuration of steam leakage are finished by the steam leakage detector.In a single day storage part that the differentiation of working condition and the measurement result of leakage rate are stored the steam leakage detector, and after checking all steam traps, the data of storage are sent in the host computer.
Host computer writes down and shows the working condition differentiation result and the leakage rate of each steam trap, the accumulative total of the leakage rate always of all steam traps and analysis and the leakage of representing with amount and excretion rate, and the time dependent leakage rate of each steam trap.
Therefore, print, the analysis of total and check result can correctly be finished automatically, the maintenance control of steam trap can easily be carried out, equally, because time dependent leakage rate is recorded and shows, repair or the replacing time by pre-determining according to leakage rate, can understand automatically and repair or the replacing time.
The bar code that will be affixed on each steam trap expression steam trap number and model by bar code reader reads in computer and to save data is input to hand labor in the computer.
The present invention has following effect unique.
Because the automatic record of host computer, accumulative total and printing testing result can be saved hand labor, save the operating time and make woprk standardization.
In addition,, can find abnormal parts and repairing or replacing early, expend to reduce product, and save the energy because the time dependent steam leakage of steam trap is recorded and shows.
Fig. 1 is the explanation block diagram of steam trap operation judging device structure of the present invention;
An embodiment of above-mentioned technique device is discussed referring to Fig. 1.
The operation judging device of steam trap of the present invention comprises steam leakage detector 1, calculates display unit 2 and host computer 3.
The operation detection part 10 of steam trap is positioned at an end of detector 1, and bar code reader is positioned at the other end.
Bar code reader is read the number of steam trap and model and they is input in the microcomputer 6 that calculates 2 li of display unit, the signal that is received by operation detection part 10 is sent to the calculating display unit by cable 12, amplify by amplifier 4, convert numeral to through A/D converter 5, then feed-in microcomputer 6.
Microcomputer 6 calculates leakage and leakage rate whether occur.On display unit 7, show, simultaneously, the number of each steam trap of storage reflection and the data of model, working condition and leakage rate in storage part 8.After all steam traps were checked, the survey data that is stored in the storage part 8 was delivered to host computer 3 from data link part 9 by cable 13.
Host computer 3 records also show the working condition of each steam trap and the differentiation result of leakage rate, and accumulative total is also analyzed total leakage rate of all steam traps and the leakage of representing with amount and excretion rate, and each steam trap over time.
Although with reference to accompanying drawing, by way of example the present invention is described in detail, should be pointed out that obviously to have multiple variation and modification to those skilled in the art.So unless these variations and modification exceed claim scope of the present invention, otherwise they will be considered to be contained in wherein.
