Description

Technical Field

[0001] This utility model relates to the field of steam generator testing technology, and in particular to steam generator testing equipment. Background Technology

[0002] Steam generators are core components in industrial production, medical equipment, and energy systems. Their performance stability directly affects the safety and reliability of end-user equipment. During the research, development, production, and quality inspection of steam generators, comprehensive testing of key parameters such as heating efficiency, liquid level control accuracy, corrosion resistance, and adaptability to operating conditions is required using specialized testing equipment. However, existing testing equipment generally suffers from the following shortcomings:

[0003] Traditional testing equipment often employs a single-station design, enabling fixed-condition testing of only one type of steam generator. For example, electrically heated steam generators require testing temperature control and current stability in a static position, while intelligent level-controlled steam generators require simulating dynamic conditions such as flipping and tilting to verify the response accuracy of the level sensor. Existing equipment cannot simultaneously meet the differentiated testing needs of both types of products. If switching test objects is required, manual replacement of fixtures and adjustment of test parameters are necessary, resulting in long testing cycles and low efficiency. This problem of insufficient equipment utilization is particularly prominent in scenarios involving parallel development of multiple product models or batch quality inspection.

[0004] Secondly, existing steam generators have stringent requirements for water quality. Particulate impurities, ionic contaminants, or microorganisms in the water can easily cause problems such as scaling of heating tubes, misjudgment of liquid level sensors, and pipe blockage, which directly affect the reliability of test data. The water supply system of existing testing equipment mostly adopts simple filtration or no filtration design, which cannot effectively remove tiny impurities and ionic contaminants. Long-term use can easily lead to damage to the internal components of the steam generator, which in turn causes deviations in test results. In addition, traditional filtration devices are mostly integrated structures, requiring the entire pipeline to be disassembled for maintenance, and the replacement of filter media is cumbersome.

[0005] Therefore, how to provide steam generator testing equipment is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide a steam generator testing device. This invention can achieve parallel testing of both electrically heated and intelligent liquid level controlled steam generators in two stations. The cleanliness of the test water source is ensured through a graded filtration water supply system. Combined with pneumatic clamps, a flipping mechanism, and a safety interlock design, it significantly improves testing efficiency, accuracy, and operational safety.

[0007] The steam generator testing equipment according to an embodiment of the present invention includes a base, a protective cover, and a water tank. A testing platform is fixedly installed on the top of the base. A first testing station and a second testing station are respectively arranged on both sides of the top of the testing platform. The protective cover is fixedly installed on the top of the testing platform, and a top plate is fixedly installed on the top of the protective cover. The water tank is fixedly installed on the top of the top plate. An electric heating steam generator and an intelligent liquid level control steam generator are respectively installed on the first testing station and the second testing station. A safety light curtain is provided on the outside of the protective cover. A dual start button, an emergency stop button, and a reset button are provided at the front end of the testing platform.

[0008] Furthermore, a filter box is embedded in the rear side of the top plate. The filter box contains at least two sets of filter layers, including a coarse filter layer and a fine filter layer. A maintenance cover is detachably installed on the top of the filter box by bolts, and water supply pipes are fixedly connected to both sides of the top. The other end of the water supply pipes is connected to the outlet of the water supply pump of the water tank. Two sets of water supply ports are provided at the bottom of the filter box. The water supply ports are connected to the inlet of the electric heating steam generator and the intelligent liquid level control steam generator respectively through quick-change hoses.

[0009] Furthermore, a first pneumatic clamp and a second pneumatic clamp are respectively provided on the front and left sides of the top of the first test station. The first pneumatic clamp is a horizontally moving clamp, and the second pneumatic clamp is a vertically pressing clamp. The electric heating steam generator achieves horizontal positioning and vertical clamping fixation through the combined action of the first and second pneumatic clamps.

[0010] Furthermore, the second test station is equipped with brackets on the front and rear sides of the top. A servo motor is fixedly installed on the inner wall of the rear bracket, and its output shaft is connected to one end of the flipping seat. The other end of the flipping seat is movably connected to the front bracket through a rotating shaft. The servo motor can drive the flipping seat to rotate around the rotating shaft to realize the flipping test of the intelligent liquid level control steam generator.

[0011] Furthermore, a third pneumatic clamp and a fourth pneumatic clamp are alternately installed on both sides of the top of the flipping seat. The third pneumatic clamp is a rotary clamping cylinder, and the fourth pneumatic clamp is a pipeline limiting clamp. The main body of the intelligent liquid level control steam generator is fixed by the third pneumatic clamp, and the steam pipeline, liquid injection pipe and water inlet pipe are clamped and limited by the fourth pneumatic clamp respectively.

[0012] Furthermore, the water tank is provided with a water inlet on the top, and a dust cover is threaded onto the water inlet. A transparent liquid level observation window is provided on the side of the water tank.

[0013] Furthermore, the electric heating steam generator is connected to a temperature sensor and a current detection module. The temperature sensor is used to detect the steam outlet temperature, and the current detection module is used to monitor the operating current. The intelligent liquid level control steam generator has a built-in reed switch liquid level sensor, and the flip base is equipped with a signal reading device for detecting the on / off state of the reed switch.

[0014] Furthermore, the protective cover adopts a frame structure, with a protective shell with observation windows on both the inside and outside. The protective door of the protective cover is equipped with a safety door switch, forming a dual-circuit safety interlock with the control system.

[0015] Furthermore, an electrical cabinet is installed below the test platform and inside the base, and the electrical cabinet integrates a PLC controller, an HMI touch screen and a quick-change connector module. The PLC controller is connected to a temperature sensor, a reed switch level sensor and a current detection module through an RS interface, and has reserved expansion functions through a USB interface. The HMI touch screen can switch to display independent test parameters of the first test station and the second test station.

[0016] Furthermore, the power supply lines and water level sensor lines of the electric heating steam generator and the intelligent liquid level control steam generator are all connected using quick-connect couplings, and the joint roots are fixed with glue.

[0017] The beneficial effects of this utility model are:

[0018] 1. The device in this utility model is equipped with a first test station and a second test station, which can simultaneously perform differentiated tests on two types of devices with different principles: electric heating steam generators and intelligent liquid level control steam generators. The first station achieves precise positioning and clamping through a combination of horizontal moving and vertical pressing pneumatic clamps, which is suitable for static performance testing of electric heating equipment. The second station supports the flipping condition testing of intelligent liquid level control equipment through a servo motor-driven flipping seat and pipeline limiting clamps. The two types of stations do not interfere with each other, which greatly shortens the testing cycle of a single device and meets the parallel testing needs of multiple product models.

[0019] 2. The filter box on the rear side of the top plate of this utility model has at least two sets of filter layers, including a coarse filter layer and a fine filter layer, which can effectively remove particulate impurities, ionic pollutants and microorganisms from the water, ensuring that the cleanliness of the water entering the steam generator meets the standards. The coarse filter layer intercepts large particulate impurities, and the fine filter layer further adsorbs fine pollutants, preventing impurities from clogging the generator pipeline or affecting the performance of the liquid level sensor and heating element, thus ensuring the accuracy of test data from the source. In addition, the removable maintenance cover on the top of the filter box is fixed with bolts, which supports quick replacement of filter media without disassembling the entire pipeline during maintenance.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] like Figure 1-5 As shown, this utility model discloses a steam generator testing device, including a base 1, a protective cover 7, and a water tank 9. A testing platform 2 is fixedly installed on the top of the base 1, with a first testing station 3 and a second testing station 4 respectively located on both sides of its top, used for testing an electrically heated steam generator 5 and an intelligent liquid level controlled steam generator 6. The protective cover 7 adopts a frame structure, with a top plate 8 fixed to the top. The water tank 9 is installed on the top of the top plate 8, and a safety light curtain 22 is installed on its outer side. The front end of the testing platform 2 is equipped with a dual start button, an emergency stop button, and a reset button, forming a safe operating interface.

[0032] The first test station 3 and the second test station 4 are key components, which can be used for the fixed operation of the electric heating steam generator 5 and the intelligent liquid level control steam generator 6, respectively.

[0033] The first test station 3 is equipped with a horizontally movable first pneumatic clamp 13 and a vertically pressing second pneumatic clamp 14 on its front and left sides, respectively. The electrically heated steam generator 5 is positioned by the horizontal clamp and pressed by the vertical clamp, achieving bidirectional fixation and ensuring stability during the test process.

[0034] Secondly, the second test station 4 is equipped with supports 15 on the front and rear sides. The rear support has a built-in servo motor 16 that drives the flipping seat 17 to rotate around the axis, realizing 0-180° flipping test. The top of the flipping seat 17 is staggered with the third pneumatic clamp 18 and the fourth pneumatic clamp 19, which respectively fix the generator body and the steam pipeline, liquid injection pipe and water inlet pipe to ensure that the pipeline does not loosen during the flipping process.

[0035] In practical use, this steam generator testing equipment can select the appropriate testing station according to the type of evaporator, and the dual-station design allows for the simultaneous testing of two different types of steam generators. For example, when testing a traditional electric heating steam generator 5, it can be installed on the first testing station 3 for testing. However, when testing an intelligent level control steam generator 6 with a reed switch level sensor, the second testing station 4 with a flip function can be selected to detect the on / off state of the reed switch, greatly improving the testing functionality, efficiency, and accuracy.

[0036] As an example of this application, a filter box 20 is embedded in the rear side of the top plate 8, which contains a coarse filter layer and a fine filter layer. A removable maintenance cover 11 is bolted to the top for easy replacement of the filter media. A water supply pipe 10 connects the water supply pump outlet of the water tank 9 to the filter box 20. Two sets of water supply ports 21 at the bottom are connected to the liquid inlets of two steam generators via quick-change hoses to achieve directional delivery of clean water. The top of the water tank 9 is equipped with a water inlet 12 and a dust cover, and a transparent liquid level observation window is provided on the side for easy monitoring of the water level.

[0037] The electrically heated steam generator 5 is connected to a temperature sensor to detect the steam outlet temperature and a current detection module to monitor the operating current. The intelligent level control steam generator 6 has a built-in reed switch level sensor, and the flip-top seat 17 is equipped with a signal reading device to detect the on / off status of the reed switch. The electrical cabinet below the test platform 2 integrates a PLC controller, an HMI touch screen, and a quick-connect module. The PLC acquires sensor data through an RS232 interface, and the HMI interface can switch between displaying independent test parameters for two stations. A USB interface is reserved for future expansion.

[0038] The protective cover 7 has an internal protective shell with an observation window. The protective door is equipped with a safety door switch, forming a double-loop safety interlock with the control system to ensure that the equipment automatically stops when the door is opened. The power supply line and water level sensor line are connected with quick-connect couplings, and the coupling base is glued to prevent loosening.

[0039] Working principle: Before testing, distilled water is injected into the water tank 9 through the water inlet 12. The water supply pump pressurizes the water into the filter box 20 through the water supply pipe 10. After coarse filtration and fine filtration, the water is delivered to the two steam generators through the quick-change hose. The operator places the electric heating steam generator 5 in the first test station 3 and starts the double start button. The first pneumatic clamp 13 and the second pneumatic clamp 14 move in sequence to complete the horizontal positioning and vertical clamping. The PLC controller triggers the power supply circuit. The temperature sensor and current detection module monitor the steam temperature and working current in real time. The data is displayed synchronously on the HMI touch screen.

[0040] For the intelligent liquid level control steam generator 6, it is installed on the tilting seat 17. The third pneumatic clamp 18 rotates and presses the main body, the fourth pneumatic clamp 19 limits the pipeline, the servo motor 16 drives the tilting seat 17 to slowly tilt, and the signal reading device detects the on / off status of the reed switch liquid level sensor in real time to determine whether the liquid level control function is normal. During the test, the safety light curtain 22 monitors the protected area in real time. If a person approaches or the protective door is opened, the system immediately triggers an emergency stop, cuts off the power source, and ensures safety. After the test, click the reset button, the clamps are released, and the equipment returns to the initial state.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
