A water pump flow control system and a fire fighting truck according to an embodiment of the present invention are described below with reference to fig. 1. It should be understood that the following description is only exemplary embodiments of the present invention and does not constitute any particular limitation of the present invention.
An embodiment of the first aspect of the present invention provides a water pump flow control system, as shown in fig. 1, including: the spray assembly 300, the detection unit, the control unit 500, the feedback actuator assembly and the water pump 100.

The control unit 500 is connected with the detection unit, the feedback performing assembly is connected with the control unit 500, and the water pump 100 is connected with the feedback performing assembly, so that the control unit 500 controls the feedback performing assembly to adjust the flow rate of the water pump 100 according to the working state of the jetting assembly 300 detected by the detection unit. The water pump 100 is connected to the spray assembly 300 to supply water to the spray assembly 300.
In use, the detection unit in the water pump flow control system detects the current working state of the spraying assembly 300 and feeds the working state back to the control unit 500, the control unit 500 receives the current working state of the spraying assembly 300 and controls the feedback execution assembly to adjust the flow of the water pump 100 according to the working state, and the water pump 100 is connected with the spraying assembly 300 to supply the water amount adapted to the current working state of the spraying assembly 300 to the spraying assembly 300.
According to the above description, the structure of the water pump flow control system is simple. Meanwhile, the water pump flow control system is provided with a detection unit, a control unit 500 and a feedback execution component. The control unit 500 can automatically control the feedback execution assembly to adjust the flow rate of the water pump 100 according to the detection result of the detection unit, so that the control unit adapts to the current working state of the injection assembly 300, manual auxiliary operation is not needed, and time and labor are saved.
In one embodiment of the present invention, the spray assembly 300 includes a plurality of spray guns. The detection unit includes a flow switch 200.
Wherein, a flow switch 200 is correspondingly arranged on each spray gun. The flow switch 200 is used to detect the operating state of the spray gun to which it is correspondingly connected. Each flow switch 200 is electrically connected to the control unit 500.
For example, as shown in FIG. 1, in this embodiment, spray assembly 300 includes two spray guns, first spray gun 301 and second spray gun 302, respectively. The number of flow switches 200 is equal to the number of spray guns. Accordingly, the detection unit comprises two flow switches 200, respectively a first flow switch 201 and a second flow switch 202.
The first flow switch 201 is installed on a 301 connecting pipeline of the first spray gun and is used for detecting the working state of the first spray gun 301; second flow switch 202 is installed on a connection line of second spray gun 302 and is used to detect an operating state of second spray gun 302. Spray gun switches are arranged on the first spray gun 301 and the second spray gun 302.

Similarly, second flow switch 202 can detect that second spray gun 302 is in an on state when the spray gun switch on second spray gun 302 is pressed.
The control unit 500 receives the feedback detection results from the first flow switch 201 and the second flow switch 202, and controls the feedback actuator to adjust the flow rate of the water pump 100 according to the feedback detection results.
It should be noted that the above-mentioned embodiment is only an illustrative embodiment of the present invention, and does not constitute any limitation to the present invention. Spray assemblies include, but are not limited to, spray guns. For example, the spraying assembly may further include a fire monitor or the like. Meanwhile, the number of the spray guns includes, but is not limited to, two, and correspondingly, the number of the flow switches 200 is equal to the number of the spray guns, including, but not limited to, two.
In one embodiment of the invention, the feedback actuator assembly includes an engine 401, an electronically controlled pump 402, and a hydraulic motor 403.
Wherein, the engine 401 is connected with an electronic control pump 402. The electronically controlled pump 402 is electrically connected to the control unit 500, so that the electronically controlled pump 402 can adjust the displacement of the electronically controlled pump 402 according to the operating state of the jetting assembly 300 detected by the detection unit. The electronically controlled pump 402 is connected to a hydraulic motor 403. The hydraulic motor 403 is connected to the water pump 100.
Further, in one embodiment of the present invention, the feedback actuator assembly further includes a directional valve 405. A directional valve 405 is connected between the electrically controlled pump 402 and the hydraulic motor 403. The direction valve 405 can be switched between a cutoff position and a conduction position.
In one embodiment of the present invention, a pressure relief valve 404 is also provided at the outlet of the electronically controlled pump 402.
Specifically, as shown in fig. 1, the engine 401 is operated at a constant speed, and in an initial state, the reversing valve 405 is at a cut-off position, and at this time, the electronically controlled pump 402 is communicated with the oil tank, and the whole control system is in an unloading state. When the reversing valve 405 is switched to the conducting position, the output oil of the electronic control pump 402 is divided into two branches, one part of the hydraulic oil is used as an external oil control source after being subjected to the pressure reduction action of the pressure reducing valve 404, and the other part of the oil enters the hydraulic motor 403 after passing through the reversing valve 405 to drive the hydraulic motor 403 to operate. When the electronic control pump 402 is not powered, the displacement of the electronic control pump 402 is minimum, and then the hydraulic motor 403 is driven to drive the water pump 100 to run at a low speed, and the whole control system is in a low-pressure low-flow standby state. When different currents are applied to the electronic control pump 402, the displacement of the electronic control pump 402 is changed accordingly, so as to drive the hydraulic motor 403 to drive the water pump 100 to operate at different rotation speeds, and finally achieve the purpose of adjusting the flow rate of the water pump 100.
When the detection unit detects that the first spray gun 301 or the second spray gun 302 is in the single start state, the water demand of the spray assembly 300 is a, the control unit 500 receives the detection result of the detection unit and controls the energization current of the electronic control pump 402 to be I according to the detection result, so that the electronic control pump 402 operates at a displacement suitable for the water demand, and further drives the hydraulic motor 403 to drive the water pump 100 to operate and provide the spray assembly 300 with the water volume suitable for the current single gun operating state.
When the detection unit detects that the first spray gun 301 and the second spray gun 302 are simultaneously in the start state, the water demand of the spray assembly 300 is 2A, the control unit 500 receives the detection result of the detection unit and controls the energization current of the electronic control pump 402 to be 2I according to the detection result, so that the electronic control pump 402 operates at a displacement suitable for the water demand, and further drives the hydraulic motor 403 to drive the water pump 100 to operate and provide the spray assembly 300 with water in a current double-gun operating state.
According to the above-described embodiment, the engine 401 in the control system operates at a constant speed, and the flow rate of the water pump 100 is indirectly adjusted by adjusting the displacement of the electronically controlled pump 402. The water pump flow control system is simple in structure and high in corresponding speed.
In one embodiment of the present invention, a diverter button 406 is attached to the diverter valve 405 as shown in FIG. 1. The direction selector button 406 is capable of controlling the direction selector valve 405 to switch between the off position and the on position.
For example, in yet another embodiment of the present invention, the selector valve 405 comprises a two-position, four-way selector valve.
When the two-position four-way reversing valve is at the cut-off position, the electric control pump 402 is communicated with the oil tank, and the electric control pump 402 is cut off from the hydraulic motor 403; when the two-position four-way reversing valve is in the conducting position, the electronic control pump 402 and the hydraulic motor 403 are communicated with each other to supply oil to the hydraulic motor 403.
Specifically, as shown in FIG. 1, in this embodiment, the reversing valve 405 uses a two-position, four-way reversing valve. The right position of the two-position four-way reversing valve is a cut-off position, and the left position of the two-position four-way reversing valve is a conducting position. A reversing button 406 is provided on the two-position four-way reversing valve. When the reversing button 406 switches the two-position four-way reversing valve to the right position, the electronic control pump 402 is communicated with the oil tank, and the whole control system is in an unloading state. When the reversing button 406 switches the two-position four-way reversing valve to the left position, the electronic control pump 402 and the hydraulic motor 403 are communicated with each other, so that the electronic control pump 402 supplies oil to the hydraulic motor 403, the hydraulic motor 403 drives the water pump 100 to operate, and finally the water pump 100 supplies water to the injection assembly 300.
In one embodiment of the invention, a relief valve 407 is connected to the outlet of the electronically controlled pump 402. The relief valve 407 includes a relief valve.
As shown in fig. 1, a relief valve is connected to an outlet of the electronically controlled pump 402. The oil inlet of the overflow valve is connected with the outlet of the electric control pump 402, and the oil outlet of the overflow valve is connected with the oil tank. The relief valve is internally set with opening pressure, when the pressure of the electronic control pump 402 exceeds the set safety pressure value of the relief valve, the relief valve is opened, hydraulic oil is discharged into the oil tank through the relief valve, and then the electronic control pump 402 is unloaded. Through the structure, the electric control pump 402 can be effectively prevented from being damaged by high pressure, and the service lives of the electric control pump 402 and the whole control system are effectively prolonged.
It should be noted that the above-mentioned embodiment is only an illustrative embodiment of the present invention, and does not constitute any limitation to the present invention. In other words, the relief valve 407 described above includes, but is not limited to, a relief valve.
In one embodiment of the present invention, a return filter 408 is mounted on the return line of the electronically controlled pump 402. A check valve 409 is provided in parallel with the return oil filter 408.
For example, as shown in fig. 1, by installing the return filter 408 on the return line of the electronic control pump 402, impurities in the returned oil can be effectively prevented from entering the oil tank, and further, the connecting line, the electronic control pump 402, the reversing valve 405, the hydraulic motor 403, the safety valve 407, and the like are polluted in the oil circulation process, and the service life of the whole water pump flow control system is prolonged. Meanwhile, the return oil filter 408 is provided with a check valve 409 in parallel, and when the return oil filter 408 is seriously blocked, the return oil cannot flow back to the oil tank through the return oil filter 408. At this time, when the pressure reaches a certain value, the check valve 409 connected in parallel to the oil return filter 408 is opened to ensure that the return oil smoothly flows back to the inside of the oil tank, thereby avoiding the occurrence of high-pressure dangerous conditions.
Embodiments of the second aspect of the invention provide a fire fighting vehicle comprising a water pump flow control system as described above.
For example, the fire engine includes a high pressure water mist fire engine.
It should be understood that the above-mentioned embodiment is only an illustrative embodiment of the present invention, and does not constitute any limitation to the present invention. In other words, the fire engine includes, but is not limited to, a high pressure water mist fire engine.
Further, since the fire engine comprises the water pump flow control system, the fire engine also has the advantages as described above.
