Description

An energy-saving rolling mill spray water system

technical field

The utility model belongs to a spray water system, in particular to an energy-saving rolling mill spray water system.

Background technique

The role of the rolling mill spray water system is to transport the turbid ring cold water to the rolling mill for spray cooling in the hot rolling mill. Since the hot rolling process of the iron and steel plant is an intermittent work system, a large amount of water is required when rolling steel, and very little water is required when not rolling steel, so the flow rate of the spray water system of the rolling mill varies greatly, which is indispensable for the hot rolling process of the iron and steel industry. missing part. A common energy-saving rolling mill spray water system is shown in Figure 1, which is mainly composed of a cold water pool 1, a spray pump 2, a regulating valve 3 and a rolling mill 4. This rolling mill spray water system lacks an effective adjustment method, and the flow rate of the rolling mill spray water system can only be controlled by frequently adjusting the valve at the rolling mill. A large part of the work of the spray pump is wasted on the adjustment valve, resulting in a waste of energy. Adjusting the valve at the rolling mill will increase the pressure of the pipe network, which will bring hidden dangers to the safety of the pipe network. In severe cases, there is a risk of pipe bursting.

Utility model content

The technical problem to be solved by the utility model is to provide a frequency conversion, speed regulation and energy saving type hot rolling swirl pool lift pump system that automatically adjusts the operation of the spray pump according to the water pressure.

In order to solve the above technical problems, the energy-saving rolling mill spray water system provided by the utility model includes a cold water pool, a spray pump and a rolling mill, the cold water pool is connected to the inlet end of the spray pump, and the The outlet end of the spray pump is connected to the rolling mill and the control end of the spray pump is connected to the frequency converter. A pressure sensor is arranged on the pipeline between the spray pump and the rolling mill. The frequency converter is electrically connected with the pressure sensor.

The energy-saving rolling mill spray water system adopts the above-mentioned technical scheme. The frequency converter automatically adjusts the operation of the spray pump by means of constant pressure water supply according to the water supply pressure monitored by the pressure sensor, and cancels the adjustment method of high energy consumption such as valve adjustment. According to The principle of the square relationship between the energy consumption of the water pump and the frequency of the frequency converter, the use of frequency conversion regulation can achieve the purpose of energy saving, and the water supply pressure of the pipe network is stable, eliminating hidden dangers in the safety of the pipe network.

In summary, the utility model is an energy-saving rolling mill spray water system that automatically adjusts the operation of the spray pump according to the water supply pressure.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

Referring to Figure 1, a common rolling mill spray water system includes a cold water pool 1, a spray pump 2, a regulating valve 3 and a rolling mill 4. Due to the lack of effective adjustment means, the flow of the spray water system of the rolling mill can only be controlled by frequently adjusting the valve at the rolling mill. A large part of the work of the spray pump is wasted on the adjusting valve, resulting in a waste of energy. The pressure of the pipe network increases, which brings hidden dangers to the safety of the pipe network, and there is a risk of pipe bursting in severe cases.

Referring to Figure 2, the energy-saving rolling mill spray water system, the cold water pool 1 is connected to the inlet end of the spray pump 2, the outlet end of the spray pump 2 is connected to the rolling mill 4 and the control end of the spray pump 2 is connected to the frequency converter 5, A pressure sensor 5 is provided on the pipeline between the spray pump 2 and the rolling mill 4 , and the frequency converter 5 is electrically connected to the pressure sensor 6 . The frequency converter 5 automatically adjusts the operation of the spray pump 2 by means of constant pressure water supply according to the water supply pressure monitored by the pressure sensor 6 .

Referring to Figure 1 and Figure 2, the utility model adds a pressure sensor 6 and a frequency converter 5, and the frequency converter 5 automatically adjusts the operation of the spray pump 2 by means of constant pressure water supply according to the water supply pressure monitored by the pressure sensor 6, replacing the valve adjustment This high energy consumption adjustment method can achieve the purpose of energy saving, and the water supply pressure of the pipe network is stable, eliminating the complete hidden danger of the pipe network.

In summary, the utility model is a safe and reliable energy-saving rolling mill spray water system.

Those skilled in the art should recognize that the above-mentioned embodiments are not used as a limitation to the present utility model, as long as within the scope of the essential spirit of the present utility model, any technical changes and modifications to the above-mentioned embodiments do not exceed the scope of the present utility model protected range.
