Description
Technical field
The present invention relates to a kind of heater cores proving installation, particularly a kind ofly simulate heat interchanger actual work temperature and pressure or the proving installation than reality more rugged surroundings.
Background technology
Air conditioning for automobiles company produces heater cores (heat interchanger used by water heating type heating system) and uses soldering tech, rosin joint (using core body after 1 year to reveal) may be there is, therefore the core body that there is rosin joint need be found out in advance, cause unnecessary infringement after preventing substandard products from dispatching from the factory.
As shown in Figures 1 to 4, existing heater cores proving installation can realize automatically testing core body whether there is rosin joint by passing into hot water in core body, but because its frock structure reason can only place a kind of core body, nobody's machine interactive interface thus common test pattern (passing into 5min85 DEG C of hot water in heater cores) can only be run, and when water temperature easily cavitation phenomenons occurs in 85 DEG C of pipelines, pipeline general pressure can not more than 0.4MPa, therefore need redesign to meet new demand.And current heat interchanger leak detection proving installation mostly is gas inspection, the method is invalid to the core body that there is rosin joint.
Summary of the invention
The present invention for solving the problem, and provides a kind of heater cores proving installation, and by theoretical analysis and calculation, construction drawing is drawn, buying, installation, and debugging and test, drop into practice and reach desired effect.
Technical solution of the present invention is: a kind of heater cores proving installation, comprise frock, water tank, water pump, electric heater, tested heater cores, electrical control cubicles, clamping plate, cylinder, solenoid valve, described clamping plate front end is provided with the water-in and water-out pipe adapter matched with the tested heater cores be arranged in frock, wherein, admitting pipe joint is connected water tank by waterpipe with water pump, titting water outlet is connected water tank by waterpipe with back-water valve (BWV), described clamping plate rear end connects cylinder, connects source of the gas by feed channel, solenoid valve, pressure regulator valve; Described water tank is built with electric heater; Described water pump, solenoid valve, pressure regulator valve, electric heater connect electrical control cubicles, for realizing proving installation automatic operating.
Described electrical control cubicles comprises PLC, touch-screen, and touch-screen connects PLC, realizes manual mode, automatic mode, alternate mode freely switch by touch-screen.
Described clamping plate front end is provided with an admitting pipe joint and two titting water outlets.
Described frock leading flank has three grooves, freely switch for the two kinds of core bodys realizing tested heater cores.
Described electrical control cubicles also comprises PID table, Power Regulation instrument, frequency converter, electronic voltmeter, and described PID table, Power Regulation instrument connect electric heater, regulates for realizing temperature; Described frequency converter, electronic voltage list catenation water pump, regulate for realizing water pressure, by increasing electrical heating power and pump head simulation environment more worse than tested core body actual operating mode, thus detects the core body that there is rosin joint in advance.
The invention has the beneficial effects as follows:
The present invention is on the basis of old device, and improved frock can place two kinds of core bodys, achieves two kinds of core bodys and arbitrarily switches; Have employed human-computer interaction interface, general mode can be realized by touch-screen, alternate mode (passes into 1min hot water in heater cores, stop water flowing 1min, hocket 10 times) and manual mode (open the parts such as electrical heating or water pump separately, observe its performance whether good) arbitrarily switch; By calculating, waterbox design and pump selection achieve system can stable operation under 95 DEG C of high-temperature water, effectively avoids cavitation phenomenons.
