Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.
[0027] The following will be combined with Figures 1 to 3 A filling pump test system provided by an embodiment of the present invention will be described. It should be understood that the following is only a schematic implementation manner of the present invention and does not constitute any special limitation to the present invention.
[0028] An embodiment of the present invention provides a filling pump test system, as Figure 1 shown. The filling pump test system includes: a filling pump 100, the filling pump 100 includes a discharge port and a hopper feed port, and a test pipeline is connected between the discharge port and the hopper feed port; a test pressure control valve 200, the test pressure control valve 200 is arranged on the test pipeline; a remote controller 300, the remote controller 300 is connected to the test pressure control valve 200 and is used for steplessly adjusting the valve opening of the test pressure control valve 200.
[0029] In the filling pump test system provided by the present invention, it includes a filling pump 100, a test pressure control valve 200, and a remote controller 300. The filling pump 100 includes a discharge port and a hopper feed port. A test pipeline is connected between the discharge port and the hopper feed port of the filling pump 100, and a test pressure control valve 200 is arranged on the test pipeline. The test pressure control valve 200 is used for adjusting the pressure of the test pipeline. The remote controller 300 is arranged in a remote area that is convenient to operate and relatively safe. The remote controller 300 is connected to the test pressure control valve 200, and it can steplessly adjust the valve opening of the test pressure control valve 200. Furthermore, it can change the pressure of the test pressure control valve 200 to perform durability tests under different pressure states.
[0030] With the above filling pump test system, the staff can infinitely adjust the valve opening of the test pressure control valve 200 through the remote controller 300 arranged in the remote safe area convenient for operation, and further, remotely and infinitely adjust the loading pressure of the filling pump test system. Thus, not only can the accuracy of test pressure adjustment be improved, but also the operation safety can be enhanced.
[0031] As Figure 1 shown, the filling pump 100 further includes an oil tank 110, a plunger oil pump 120, a plunger oil pump motor, an oil-based overflow valve 130, an oil-based directional valve 140, an oil-based hydraulic cylinder 150, a water-based hydraulic cylinder 160, a water-based swing valve 170, and a hopper 180. A hopper feed inlet is provided on the hopper 180. The plunger oil pump motor drives the plunger oil pump 120 to operate. The plunger oil pump 120 sucks in low-pressure oil from the oil tank 110 and converts it into high-pressure oil and transports it to the oil-based directional valve 140. The oil-based overflow valve 130 is connected in parallel to the main oil circuit to play a role in high-pressure overflow protection. The oil-based directional valve 140 controls the forward and backward movement of the oil-based hydraulic cylinder 150. The oil-based hydraulic cylinder 150 is connected to the water-based hydraulic cylinder 160 through a mechanical structure. The oil-based hydraulic cylinder 150 drives the water-based hydraulic cylinder 160 to move forward and backward. The water-based hydraulic cylinder 160 inputs the medium in the hopper 180 of the filling pump 100 into the discharge port of the filling pump 100 through the water-based swing valve 170. The discharge port of the filling pump 100 is connected to the hopper feed inlet through a test pipeline.
[0032] In an embodiment of the present invention, it further includes: a liquid tank 400, the liquid tank 400 is connected between the discharge port and the hopper feed inlet; a reflux control assembly, the reflux control assembly is arranged between the liquid tank 400 and the hopper feed inlet; the remote controller 300 is connected to the reflux control assembly and is used to adjust the flow rate of the reflux control assembly; the test pressure control valve 200 is arranged between the discharge port and the liquid tank 400.
[0033] For example, as Figure 1 shown, a liquid tank 400 is arranged between the discharge port and the hopper feed inlet of the filling pump 100. During the test, the liquid output from the discharge port of the filling pump 100 first enters the liquid tank 400, and then the liquid in the liquid tank 400 enters the hopper feed inlet. A reflux control assembly is arranged between the liquid tank 400 and the feed hopper 180. The remote controller 300 is connected to the reflux control assembly. The remote controller 300 can adjust the flow rate entering the hopper feed inlet through the reflux control assembly to prevent the overflow phenomenon of the hopper 180.
[0034] More specifically, in an embodiment of the present invention, the reflux control assembly includes: a centrifugal pump 520, which is connected to the liquid tank 400; a reflux pressure control valve 510, which is connected between the centrifugal pump 520 and the hopper feed inlet; and a remote controller 300, which is connected to the reflux pressure control valve 510 and is used to steplessly adjust the opening degree of the reflux pressure control valve 510.
[0035] For example, as Figure 2 shown, both the reflux pressure control valve 510 and the test pressure control valve 200 are electric sleeve plunger valves. The electric sleeve plunger valve includes an electric actuator 210, an upper valve body 220, a lower valve body 230, a valve sleeve 240, a valve core 250, and a force output rod 260. Among them, the upper valve body 220 is butt-connected to the lower valve body 230. The lower valve body 230 is provided with a cavity, and a low-pressure port and a high-pressure port are opened thereon. The valve sleeve 240 is installed in the cavity of the lower valve body 230, and the valve core 250 is sleeved into the valve sleeve 240. The force output rod 260 passes through the upper valve body 220 and is connected to the valve core 250. The electric actuator 210 is connected to the force output rod 260. During the working process, the electric actuator 210 can drive the force output rod 260 to move, and the force output rod 260 drives the valve core 250 to move, thereby changing the valve opening degree between the valve core 250 and the high-pressure port, and further adjusting the pressure of the electric sleeve plunger valve. For example, the electric actuator 210 includes a stepper motor, a speed reducer, and a lead screw. The remote controller 300 is a host computer. The host computer controls the PLC to send a pulse signal, and the pulse signal controls the stepper motor to rotate. The output torque is increased by the speed reducer, and the increased torque is a rotational motion, which is then converted into a linear motion by the lead screw. The lead screw is mechanically connected to the valve core 250 through the force output rod 260, thereby driving the valve core 250 to move up and down to adjust the valve opening degree.
[0036] In an embodiment of the present invention, it further includes: a first flow rate detection device 610, which is arranged between the discharge port and the test pressure control valve 200; and a second flow rate detection device 620, which is arranged between the reflux pressure control valve 510 and the hopper feed inlet.
[0037] Furthermore, in an embodiment of the present invention, the remote controller 300 is connected to the first flow rate detection device 610 and the second flow rate detection device 620, and is used to control the valve opening degree of the reflux pressure control valve 510 based on the detection results of the first flow rate detection device 610 and the second flow rate detection device 620.
[0038] To prevent the overflow phenomenon of the hopper 180, as Figure 3As shown, before the durability test, it is necessary to determine the initial value of the reflux pressure control valve 510, that is, a preliminary test needs to be carried out. Specifically, when the medium flows through the first flow detection device 610, the first flow detection device 610 transmits the detection result to the remote controller 300. The remote controller 300 records the flow value Q1 of the first flow detection device 610 at this time and turns on the centrifugal pump 520, so that the centrifugal pump 520 extracts the medium from the liquid tank 400. The medium enters the hopper 180 after flowing through the second flow detection device 620 and the reflux pressure control valve 510. During this process, the remote controller 300 continuously adjusts the valve opening of the reflux pressure control valve 510 until the flow value of the second flow detection device 620 is equal to Q1, and records the valve opening of the reflux pressure control valve 510 at this time as k1, so as to provide the initial setting value of the reflux pressure control valve 510 for the subsequent durability test, ensure that the liquid ejected from the discharge port of the filling pump 100 is basically equal to the liquid recovered at the liquid inlet of the hopper, and prevent overflow.
[0039] In an embodiment of the present invention, as Figure 1 shown, the filling pump test system further includes: a heightening wall 800, and the heightening wall 800 is used to connect to the hopper 180 of the filling pump 100 to increase the height of the hopper 180 of the filling pump 100. Thereby, it can prevent the medium from splashing, avoid medium loss, and ensure a clean test environment.
[0040] During the long-term durability test, the flow rate of the filling pump 100 itself fluctuates. When the flow rate ejected by the filling pump 100 fluctuates and is more than the flow rate supplied by the centrifugal pump 520, after a long-term accumulation, the medium will overflow from the hopper 180. Based on this, in an embodiment of the present invention, the filling pump test system further includes: a liquid level detection device 630, and the liquid level detection device 630 is used to detect the liquid level of the hopper of the filling pump 100; the remote controller 300 is connected to the liquid level detection device 630 and is used to adjust the valve opening of the reflux pressure control valve 510 based on the detection result of the liquid level detection device 630. In addition, the filling pump test system further includes: a first flow detection device 610, and the first flow detection device 610 is arranged between the discharge port and the test pressure control valve 200; a second flow detection device 620, and the second flow detection device 620 is arranged between the reflux pressure control valve 510 and the hopper inlet.
[0041] Specifically, at the start of the durability test, the remote controller 300 adjusts the valve opening of the return pressure control valve 510 to the valve opening k1 of the return pressure control valve 510 obtained in the preliminary test, and records the liquid level value of the liquid level detection device 630 at this time as the initial liquid level value Lc; the centrifugal pump 520 and the filling pump 100 are turned on. After the filling pump 100 operates stably for 5 minutes, the valve opening of the test pressure control valve 200 is adjusted through the remote controller 300 so that the detection result of the first pressure detection device 640 reaches the specified test value to conduct the durability test. During the entire process of the durability test, the liquid level detection device 630 continuously monitors the liquid level L of the fluid medium in the hopper 180. If the liquid level L in the hopper 180 is outside Lc±△L, the remote controller 300 controls and adjusts the valve opening of the return pressure control valve 510 until L is within Lc±△L; if the liquid level L in the hopper 180 is within Lc±△L, the durability test continues until the target test duration of the durability test is reached. For example, △L can take a value of 5 mm.
[0042] In another embodiment of the present invention, the filling pump 100 further includes: a circulating cooling unit, which is connected to the liquid tank 400 and is used to cool the liquid in the liquid tank 400.
[0043] Further, in an embodiment of the present invention, as Figure 1 shown, the circulating cooling unit includes: a cooling tower 710, which is connected to the liquid tank 400; a cooling circulation power device 720, which is arranged between the cooling tower 710 and the liquid tank 400.
[0044] Specifically, for example, the cooling circulation power device 720 includes a cooling circulation pump. During the durability test process, after the remote controller 300 adjusts the valve opening of the return pressure control valve 510 to k1 and records the liquid level value of the liquid level detection device 630 as the initial liquid level value Lc, the cooling circulation pump is turned on, so that the liquid medium in the liquid tank 400 enters the cooling tower 710, and the medium cooled by the cooling tower 710 returns to the liquid tank 400. Thus, the liquid medium in the liquid tank 400 is always in a low-temperature state to prevent the medium from getting hot and ensure the smooth progress of the durability test.
[0045] In addition, a filter is further provided between the discharge port and the test pressure control valve 200 to ensure the cleanliness of the liquid medium.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
