Description

绝缘子水冲洗闭环水压控制系统Insulator water flushing closed-loop water pressure control system

技术领域：Technical field:

本实用新型与绝缘子水冲洗系统有关，尤其与闭环水压控制有关。The utility model relates to an insulator water flushing system, in particular to a closed-loop water pressure control.

背景技术：Background technique:

电气化铁路和供电站绝缘子污闪现象是困扰线路正常供电的重要问题。避免污闪的有效办法是定期对绝缘子进行水冲洗作业。传统的清洗采用人工擦洗的办法，不仅劳动强度大、危险性高，而且需开天窗时间，大大降低了清洗效率。因此，具有冲洗效果好、不需专门开天窗时间的带电(不带电)水冲洗系统解决了上述问题，是绝缘子清洗的有力手段。Pollution flashover of insulators in electrified railways and power supply stations is an important problem that plagues the normal power supply of lines. An effective way to avoid pollution flashover is to regularly wash the insulators with water. The traditional cleaning method adopts manual scrubbing, which is not only labor-intensive and dangerous, but also requires time to open the skylight, which greatly reduces the cleaning efficiency. Therefore, the charged (non-charged) water flushing system with good flushing effect and no need to open the skylight time solves the above problems, and is a powerful means for cleaning insulators.

现有的绝缘子水冲洗水压系统采用开环控制。由于离心泵的流量脉动较大，因此开环系统的工作压力具有一定的波动，造成一定的流量脉动，在一定程度上影响冲洗效果并可能造成接触网的波动，存在以下不足：一是冲洗流量脉动太大；二是流量易受干扰；三是压力不太稳定；四是用水量较大。The existing insulator water flushing hydraulic system adopts open-loop control. Due to the large flow pulsation of the centrifugal pump, the working pressure of the open-loop system has a certain fluctuation, resulting in a certain flow pulsation, which affects the flushing effect to a certain extent and may cause fluctuations in the catenary. There are the following deficiencies: First, the flushing flow The pulsation is too large; the second is that the flow is easily disturbed; the third is that the pressure is not stable; the fourth is that the water consumption is large.

实用新型的内容：Contents of the utility model:

本实用新型的目的是提供一种绝缘子水冲洗闭环水压控制系统，保证冲洗压力和流量具有较好的稳定性。The purpose of the utility model is to provide a closed-loop water pressure control system for insulator water flushing, which can ensure good stability of flushing pressure and flow.

本实用新型是这样实现的：The utility model is achieved in that:

本实用新型绝缘子水冲洗闭环水压控制系统，水泵2的出水口并联安装有电动调节阀5，水泵2的出水管道上装有压力传感器1和喷嘴，压力传感器1的信号输出端与控制器6的输入信号端连接，控制器6的输出端与电动调节阀的电信号输入控制端连接。The utility model insulator water flushing closed-loop water pressure control system, the water outlet of the water pump 2 is installed in parallel with the electric regulating valve 5, the water outlet pipe of the water pump 2 is equipped with a pressure sensor 1 and a nozzle, the signal output end of the pressure sensor 1 and the controller 6 The input signal end is connected, and the output end of the controller 6 is connected with the electric signal input control end of the electric regulating valve.

电磁水阀3并联在水泵2的出口。The electromagnetic water valve 3 is connected in parallel with the outlet of the water pump 2.

本实用新型采用闭环控制系统。通过检测反馈系统的实际工作压力，实时与控制压力值相比较，出现偏差时进行电动调节阀5开口的调节，始终保证系统压力的稳定性，从而保证喷嘴出水流量的稳定性，提高冲洗效果。同时，由于采用电动调节阀调节系统压力，使水泵工作在高效、经济区，不仅工作效率高，而且寿命长，可方便实现一组水泵电机带动多个水炮同时进行水冲洗作业。The utility model adopts a closed-loop control system. By detecting the actual working pressure of the feedback system and comparing it with the control pressure value in real time, the opening of the electric control valve 5 is adjusted when there is a deviation, so as to always ensure the stability of the system pressure, thereby ensuring the stability of the nozzle water flow and improving the flushing effect. At the same time, because the electric regulating valve is used to adjust the system pressure, the water pump works in a high-efficiency and economical area, which not only has high working efficiency, but also has a long life.

具体实施方式：Detailed ways:

本实用新型为绝缘子水冲洗闭环水压控制系统，电动调节阀5和电磁水阀3并联在水泵2的出口，压力传感器1的入口与水泵2的出口相连。压力传感器1的输出电信号pc与压力输入控制信号pi分别与控制器6的输入信号端和反馈信号端相连，控制器6的输出信号与电动调节阀5的电信号输入控制端相连。电动调节阀5的型号为ZAEP-1.6，压力传感器1的的型号为TEYB-KO-K-A-G，控制器6的型号为APS-D2-S2-10。The utility model is an insulator water flushing closed-loop water pressure control system, the electric regulating valve 5 and the electromagnetic water valve 3 are connected in parallel at the outlet of the water pump 2, and the inlet of the pressure sensor 1 is connected with the outlet of the water pump 2. The output electrical signal p c of the pressure sensor 1 and the pressure input control signal p i are respectively connected to the input signal terminal and the feedback signal terminal of the controller 6 , and the output signal of the controller 6 is connected to the electrical signal input control terminal of the electric regulating valve 5 . The model of the electric regulating valve 5 is ZAEP-1.6, the model of the pressure sensor 1 is TEYB-KO-KAG, and the model of the controller 6 is APS-D2-S2-10.

压力传感器1用来检测、反馈水泵的出口工作压力。The pressure sensor 1 is used to detect and feedback the outlet working pressure of the water pump.

电磁水阀3在暂停冲洗时让水泵卸荷，出水直接和进水相通，实现节能节水。The electromagnetic water valve 3 allows the water pump to unload when the flushing is suspended, and the outlet water directly communicates with the inlet water, so as to realize energy saving and water saving.

水泵2的出口可同时连接多个炮嘴，进行同时和独立水冲洗作业。The outlet of the water pump 2 can be connected to a plurality of nozzles at the same time to perform simultaneous and independent water flushing operations.

电动调节阀5的调压作用可使水泵工作在经济、高效区。The pressure regulation function of the electric regulating valve 5 can make the water pump work in the economical and efficient area.

当水泵2的出口压力与控制压力出现偏差时，产生一个偏差值控制电动调节阀5的开口，直到实际出口压力等于控制压力。采用不同直径大小的喷嘴时，喷嘴的进口压力不受影响，只与控制值有差，从而可较好地保证不同直径喷嘴所对应的喷射流量。When the outlet pressure of the water pump 2 deviates from the control pressure, a deviation value is generated to control the opening of the electric regulating valve 5 until the actual outlet pressure is equal to the control pressure. When nozzles with different diameters are used, the inlet pressure of the nozzles is not affected, but only differs from the control value, so that the injection flow corresponding to nozzles with different diameters can be better guaranteed.
