Abstract
The utility model discloses an efficiency detection instrument of a water chilling unit. The efficiency detection instrument comprises an ultrasonic flowmeter, a temperature transmitter, a data acquisition box, a communication control box, an intelligent ammeter and a computer, wherein the ultrasonic flowmeter and the temperature transmitter are respectively connected with the input end of the data acquisition box through feeder lines; one end of the data acquisition box is connected with the computer through the communication control box; and the other end of the data acquisition box is connected with the intelligent ammeter. Since the ultrasonic flowmeter, which is adopted by the efficiency detection instrument, is externally clamped or installed on a pipeline so as to perform real-time measurement, is connected with the intelligent ammeter capable of performing power real-time measurement and the temperature transmitter capable of performing temperature real-time measurement, and is connected with the computer through the communication control box, the efficiency detection instrument can be installed without damaging the pipeline, and is simple, easy, convenient and rapid in operation.
Description
Technical field
The utility model relates to a kind of checkout equipment, particularly relates to a kind of chiller efficiency detector.
Background technology
At present, handpiece Water Chilling Units is used every field widely.In order to keep the good running status of handpiece Water Chilling Units; Need the daily detection of carrying out to chiller efficiency; And fast measuring is carried out at the scene of other running state parameter of unit instruct energy-conservation, the safe operation state of handpiece Water Chilling Units with calculating, so that rationally arrange dynamically maintenance.The chiller efficiency tester system commonly used is complicated, wiring is loaded down with trivial details, debugging difficulty is big, mostly need destroy the piping erection flowmeter (as, orifice plate, vortex street, electromagnetism), use inconvenient.
The utility model content
The purpose of the utility model is to provide a kind of chiller efficiency detector easy to use.
For realizing above-mentioned purpose, the technical solution of the utility model is:
The utility model is a kind of chiller efficiency detector, and it comprises ultrasonic flow meter, temperature transmitter, data acquisition device, Communication Control case, intelligent electric meter, computer; Described ultrasonic flow meter and temperature transmitter are connected the input end of data acquisition device respectively through feeder line, an output terminal of data acquisition device is connected another output terminal connection of intelligent ammeter of data acquisition device through the Communication Control case with computer.
After adopting such scheme; Because the utility model adopts the ultrasonic flow meter of pipeline in real time measuring flow with pressing from both sides or be installed in outward; Be connected with the temperature transmitter that can measure the intelligent electric meter of power in real time, measure temperature in real time; And be connected with computer through the Communication Control case, need not to destroy pipeline and just can install, what operate is simple and easy, convenient, fast; A people can accomplish the mensuration and the calculating of pump efficiency, flow, unit power consumption amount and other parameter of unit in the short period of time, realizes that really the unit performance test is made a practice of, day-to-day.
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
Description of drawings
Fig. 1 is the structured flowchart of the utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of chiller efficiency detector, and it comprises ultrasonic flow meter 1, temperature transmitter 2, data acquisition device 3, Communication Control case 4, intelligent electric meter 5, computer 6.
Described ultrasonic flow meter 1 and temperature transmitter 2 are connected the input end of data acquisition device 3 respectively through feeder line, an output terminal of data acquisition device 3 is connected another output terminal connection of intelligent ammeter 5 of data acquisition device 3 through Communication Control case 4 with computer 6.
During use, with external clamping ultrasonic flow meter 1 probe clip or be installed on the outlet conduit 10 of the handpiece Water Chilling Units of flowing through.Two probes 21,22 of temperature transmitter 2 are clipped in respectively or are installed on the outlet conduit 10 and water return pipeline 20 of the handpiece Water Chilling Units of flowing through.
The characteristics of the utility model:
1, selects ultrasonic flow meter 1 probe for use.Available external clamping ultrasonic flow probe (can install) in the situation that not destroy pipeline, compared with can only the flowmeter that destroys piping erection (as, orifice plate, vortex street, electromagnetism) have a convenience.
2, signal is gathered nearby.Temperature, flow measuring point near, measurement parameter (possibly be voltage, current signal) is collected through data acquisition device 3 and is changed into numeral (1,2,3), accomplishes data transmission with the RS485 communication network again, the accuracy height.
3, computer 6, Communication Control case 4, data acquisition device 3 are located at different positions.
The emphasis of the utility model just is: external clamping ultrasonic flow meter and temperature transmitter.
The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
