[0019] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.
[0020] refer to Figure 1In a preferred embodiment, the MTU956 diesel engine critical pump performance testing system includes: at least one test pump 2; a test bench 1, which is equipped with a mounting base 11 for mounting the test pump 2 and a servo motor 12 connected to the mounting base 11 for driving the test pump 2; and an industrial control computer 4 connected to the servo motor 12 for controlling its start and stop. The inlet of the test pump 2 is connected to the outlet of the corresponding medium system 3, and the outlet of the test pump 2 is connected to the inlet of the corresponding medium system 3. The medium in the medium system 3 is pressurized by the test pump 2 and flows out from its outlet to form a fluid loop. The test bench 1 also includes at least one measuring instrument 13 disposed between the outlet of the test pump 2 and the inlet of the medium system. The measuring instrument 13 is used to measure the actual fluid parameters at the outlet of the test pump 2 to determine the performance of the test pump.
[0021] It can be understood that the test pump 2 in this embodiment refers to the important onboard pumps of the MTU956 diesel engine, including the coolant pump, fuel pump, and lubricating oil pump to be tested. Correspondingly, the media system includes the coolant media system 31, the fuel media system 32, and the lubricating oil media system 33. That is to say, as Figure 2 As shown, when test pump 2 is a cooling water pump, the medium system connected to the MTU956 diesel engine important pump performance test system is the cooling water medium system 31. When test pump 2 is a fuel pump, the medium system connected to the MTU956 diesel engine important pump performance test system is the fuel medium system 32. When test pump 2 is a lubricating oil pump, the medium system connected to the MTU956 diesel engine important pump performance test system is the lubricating oil medium system 33.
[0022] Optionally, the mounting base 11 may have pre-drilled holes that match the mounting interfaces of different types of test pumps 2. The size and shape of these pre-drilled holes are precisely designed to ensure that the corresponding pump can be securely mounted on the test bench and can be easily disassembled and replaced.
[0023] Specifically, the outlet pressure of test pump 2 is configured to be between 5 bar and 16 bar. Servo motor 12 is a 3-phase AC motor with a power configuration of 7.5 kW and a maximum speed of 2800 rpm.
[0024] In some embodiments, the industrial control computer 4 also includes a human-machine interface, which is used to receive user-triggered operations to generate motor start control commands or motor stop control commands, and to communicate with the measuring instrument 13 to receive and display the actual fluid parameters measured by the measuring instrument 13.
[0025] In some embodiments, reference is made to Figure 3The cooling water medium system 31 includes a cooling water tank 31-1, a first filter 41, a first valve 42, a safety relief valve 43, a first flow meter 44, and a second flow meter 45. The first filter 41 is installed in the cooling water tank 31-1. The first valve 42 is installed between the inlet of the test pump 2 and the outlet of the cooling water tank 31-1. The safety relief valve 43, the first flow meter 44, and the second flow meter 45 are sequentially installed between the outlet of the test pump 2 and the inlet of the cooling water tank 31-1, and are connected in parallel. It can be understood that the cooling water from the cooling water tank 31-1 flows out of the outlet of the cooling water tank 31-1 through the first filter 41, enters the cooling water pump through the first valve 42, is pressurized by the cooling water pump, flows out of its outlet, and then flows back into the cooling water tank 31-1 through the safety relief valve 43 and the flow meter, thus forming a cooling water circulation loop. In this embodiment, the measuring instrument 13 is installed between the outlet of the cooling water pump and the pipe connected to the safety relief valve 43.
[0026] In some embodiments, reference is made to Figure 4 The fuel medium system 32 includes a fuel tank 32-1, a first filter 41, a second filter 46, a first valve 42, a safety relief valve 43, a first flow meter 44, and a second flow meter 45. The first filter 41 and the second filter 46 are connected in parallel and are disposed within the fuel tank 32-1. The first valve 42 is disposed between the inlet of the test pump 2 and the outlet of the fuel tank 32-1. The safety relief valve 43, the first flow meter 44, and the second flow meter 45 are sequentially disposed between the outlet of the test pump 2 and the inlet of the fuel tank 32-1, and are connected in parallel. It can be understood that fuel from the fuel tank 32-1 flows out of the outlet of the fuel tank 32-1 through the first filter 41 and the second filter 46, enters the fuel pump through the first valve 42, is pressurized by the fuel pump, flows out of its outlet, and then flows back into the fuel tank 32-1 through the safety relief valve 43 and the flow meter, thus forming a fuel circulation loop.
[0027] In some embodiments, reference is made to Figure 5The lubricating oil medium system 33 includes a lubricating oil tank 33-1, a first filter 41, a second filter 46, a first valve 42, a safety relief valve 43, a first flow meter 44, and a second flow meter 45. The first filter 41 and the second filter 46 are connected in parallel and are disposed in the lubricating oil tank 33-1. The first valve 42 is disposed between the inlet of the test pump 2 and the outlet of the lubricating oil tank 33-1. The safety relief valve 43, the first flow meter 44, and the second flow meter 45 are disposed sequentially between the outlet of the test pump 2 and the inlet of the lubricating oil tank 33-1, and are connected in parallel. It can be understood that the lubricating oil in the lubricating oil tank 33-1 flows out of the outlet of the lubricating oil tank 33-1 through the first filter 41 and the second filter 46, and enters the lubricating oil pump through the first valve 42. After being pressurized by the lubricating oil pump, it flows out from its outlet and then flows back into the lubricating oil tank 33-1 through the safety relief valve 43 and the flow meter, thus forming a lubricating oil circulation loop.
[0028] It should be noted that, in the embodiments of this application, the filter also has the function of buffering and depressurizing when the fluid pressurized by the test pump enters the water tank or oil tank in the fluid circuit and before flowing out of the water tank or oil tank.
[0029] The embodiments of the present invention can achieve the following technical effects: 1. This product can perform offline testing of the performance of important pumps such as the MTU956 diesel engine's onboard water pump, fuel pump, and lubricating oil pump.
[0030] 2. Based on the structural characteristics of the important pumps of the MTU956 diesel engine, convenient and quick pump testing can be achieved without changing the connection form of the MTU956 diesel engine pump.
[0031] 3. The combination of hardware and software enables automatic control of the speed and torque of the variable frequency motor, eliminating the reliance on the experience and skills of maintenance personnel.
[0032] 4. It has a simple structure, low cost, and is flexible in use.
[0033] 5. It is highly adaptable and can be extended to other diesel engines with simple improvements.
[0034] Figure 6 A schematic diagram of the structural principle of a performance testing system for critical pumps in an MTU956 diesel engine, according to a specific embodiment, is shown. (Combined with...) Figure 6Taking the cooling water pump test as an example, the test process includes: the industrial control computer can control the opening of the first valve and the flow meter valve (Figures 32-1 and 33-1), start the servo motor, and the cooling water pump to be tested draws water from the cooling water tank through the pipe connected to S1. The water flows through the first filter and the first valve, reaches the water pump, and after being pressurized by the water pump, flows out from the B1 outlet; the water flows through the pipe equipped with a safety relief valve, passes through the flow meter, and returns to the water tank.
[0035] In some embodiments, the measuring instruments include a temperature gauge and a pressure gauge, wherein the temperature gauge is used to measure the actual temperature of the fluid at the outlet of the test pump, and the pressure gauge is used to measure the actual pressure of the fluid at the outlet of the test pump. Optionally, the measuring instruments also include a pressure sensor redundantly configured with the pressure gauge. Figure 6 The numbers 7-1, 7-2, and 7-3 shown are thermometers. Figure 6 The labels 9-1, 9-2, and 9-3, and 10-1, 10-2, and 10-3, respectively, represent pressure gauges and pressure sensors. It is understood that in this embodiment of the invention, the number of measuring instruments can be determined according to the needs of the media system; that is, all media systems can share the same set of measuring instruments, or each media system can be configured with a separate set of measuring instruments (e.g., ...). Figure 6 As shown, all of them fall within the scope of protection of this application.
[0036] It should be noted that the specific structural composition of the media system in the embodiments of this application can also refer to relevant existing mature technologies, see below. Figure 6 For example, depending on the specific structure of the media system required for actual operation, it may include, but is not limited to, pressure gauge switch connectors, pressure sensors, two-piece ball valves, manual valves, level gauges with check valves, level control relays, electric heaters, shut-off valves, etc., and their specific quantities can be set according to the corresponding type of media system, which will not be elaborated here. It is understood that the first or second flow meter can also be an ultrasonic flow meter, and correspondingly, the second or first flow meter can be a conventional flow meter. The temperature gauge can be a temperature transmitter. The water tank or oil tank can be a closed storage tank. In some embodiments, a high-pressure hose can be used to connect the inlet of the test pump to the first valve, and a high-pressure hose can also be used to connect the outlet of the test pump to the safety relief valve. The relief valve is an automatic valve used to release excess fluid (such as water, steam, or gas) when the system pressure exceeds a set value to prevent excessive system pressure from causing equipment damage or safety accidents. Optionally, the safety relief valves for fuel media systems and lubricating oil media systems can also be relief valves with relatively lenient design standards.
[0037] In some embodiments, the test system is equipped with a manual pump for static pressure testing of the pump. Optionally, the oil tank / cooling water tank volume can be 200–300 liters. A closed-type pressure oil tank is initially adopted, with a reinforced tank structure and the elimination of the breather. This allows for meeting the pump's oil intake requirements while reducing the tank volume and preventing air intake. The oil tank / cooling water tank dimensions (external) are preferably 900×700×600mm to meet the on-site requirements of "mobile equipment with a compact and aesthetically pleasing appearance."
[0038] Specifically, the industrial control computer may include a data acquisition and control module, a servo motor drive controller, motor starting and protection components, test control software, and a human-machine interface. Through the touch screen of the human-machine interface, the motor can be started and stopped, parameters can be set, and motion control commands for the actuator can be executed. Various physical signals such as pressure signals, oil temperature, and flow rate can be displayed, as well as various alarms. The operating parameters and curves such as motion control command signals, flow rate, and pressure signals can be displayed in real time, providing a reliable basis for test conclusions.
[0039] This embodiment marks the first successful implementation of refurbished testing of an MTU956 diesel engine pump, ensuring the pump's performance after repair and refurbishment. The system is equipped with fuel, lubricating oil, and cooling water tanks, enabling testing of various pump types. The system's electronic control system also features self-diagnosis and protection, detecting the status of sensors and their circuitry through self-testing, reducing the probability of data errors. The system has historical data storage capabilities, allowing for the setting of different equipment models and parameters, facilitating the accumulation and comparison of operational experience data from similar equipment.
