The flow controller 6 accurately controls the frequency converter according to the preset grouting flow and the real-time feedback grouting flow information of the sensor, so as to ensure the stability of the grouting flow.

[0033] With reference to Figure 1 - Figure 3 The heat dissipation assembly one comprises a coiled pipe 4, the coiled pipe 4 is sleeved on the outside of the variable frequency speed regulation three-phase asynchronous motor 3, one end of the coiled pipe 4 is fixedly connected with a water storage tank 5, the outside of the water storage tank 5 is fixedly connected with a hose 11, the top of the bottom plate 1 is fixedly connected with a water pump 12, the output end of the water pump 12 is fixedly connected at the end of the hose 11 away from the water storage tank 5, the input end of the water pump 12 is fixedly connected at the end of the coiled pipe 4 away from the water storage tank 5, the water storage tank 5 is used to store the cooling liquid, the design of the water storage tank 5 can achieve heat preservation and leakage prevention and other functions, so as to ensure the effective use of the cooling liquid, the hose 11 is used to connect the water storage tank 5 and the water pump 12, forms part of the cooling liquid circulation path, so that the cooling liquid can flow between the water storage tank 5 and the coiled pipe 4, realizes effective cooling circulation, and the water pump 12 is the power source for the circulation of the cooling liquid in the coiled pipe 4.

[0034] With reference to Figure 1 - Figure 3 The control assembly comprises the flow controller 6, and the top of the flow controller 6 is provided with a heat dissipation assembly two. The heat dissipation assembly two comprises a plurality of heat dissipation fans 7 fixedly connected at the top of the flow controller 6. The flow controller 6 is used to adjust the frequency of the variable frequency speed regulation three-phase asynchronous motor 3 to change the speed thereof, and then adjust the speed of the grouting pump 2. The heat dissipation fans 7 are used to dissipate heat of the flow controller 6, so as to ensure the high efficiency of the work.

[0035] With reference to Figure 1 - Figure 3The flow controller 6 is electrically connected with the variable frequency speed regulation three-phase asynchronous motor 3, the inner side of the serpentine pipe 4 is close to the outer side of the variable frequency speed regulation three-phase asynchronous motor 3, the serpentine pipe 4 is used for bearing the cooling liquid inside, thereby taking away the heat generated by the variable frequency speed regulation three-phase asynchronous motor 3 during operation, and ensuring the good working performance and stability of the variable frequency speed regulation three-phase asynchronous motor 3.

[0036] With reference to Figure 1 and Figure 3 The top of the water storage tank 5 is fixedly connected with a water inlet pipe 10, the outer side of the water inlet pipe 10 is fixedly connected with a valve 8, the water inlet pipe 10 is used for injecting the cooling liquid into the inside of the water storage tank 5, and the valve 8 is used for controlling the opening and closing of the water inlet pipe 10.

[0037] With reference to Figure 1 and Figure 3 The bottom of the water storage tank 5 is fixedly connected with a water outlet pipe 13, the outer side of the water outlet pipe 13 is fixedly connected with a valve 9, the water outlet pipe 13 is used for discharging the cooling water in the water storage tank 5, and the valve 9 is used for controlling the opening and closing of the water outlet pipe 13.

[0038] Working principle: the flow controller 6, variable frequency speed regulation three-phase asynchronous motor 3 and grouting pump 2 are connected. In the test, when the grouting flow needs to be changed, the operator can adjust the parameters of the flow controller 6 (such as adjusting the proportional, integral and differential coefficients in the PID controller), or directly set the target flow value. The flow controller 6 will send a control signal to the flow frequency converter according to the set requirements, and the frequency of the variable frequency speed regulation three-phase asynchronous motor 3 can be adjusted in real time through the flow frequency converter, so that the frequency of the variable frequency speed regulation three-phase asynchronous motor 3 can be adjusted from 5-50Hz, and the speed of the variable frequency speed regulation three-phase asynchronous motor 3 is adjusted, the grouting flow range of 1.07-8.45L / min is realized, and finally the control of the output flow of the grouting pump 2 is realized. For example, when the grouting flow needs to be increased from a lower flow to a higher flow, the flow controller 6 will send a signal to the frequency converter to increase the output frequency, which will increase the speed of the variable frequency speed regulation three-phase asynchronous motor 3, and when the motor speed increases, the plunger movement speed of the grouting pump 2 or the rotation speed of the impeller increases (depending on the type of grouting pump 2), so that the amount of slurry output per unit time increases, thereby realizing the grouting flow range of 1.07-8.45L / min. At the same time, the stopwatch is used to measure the grouting amount of 1min as the standard grouting flow, and the slurry flow of 1min at the rated power is used as the standard for constant flow grouting. This means that during the grouting process, the grouting pump 2 outputs a constant amount of slurry per minute by adjusting the frequency of the flow controller 6, realizing constant flow grouting. When the variable frequency speed regulation three-phase asynchronous motor 3 is working, the motor is cooled by installing the serpentine pipe 4 on the outside, and during operation, the water pump 12 will deliver the cooling water in the water storage tank 5 to the inside of the serpentine pipe 4, and then return to the inside of the water storage tank 5 from the other end of the serpentine pipe 4, forming a circulating flow. In this way, the cooling water can timely take away the heat generated by the motor during work, thereby ensuring its good working performance and stability. Effectively improve the heat dissipation efficiency of the variable frequency speed regulation three-phase asynchronous motor 3, and ensure its efficient and stable operation.
