Balanced containers are widely used in different industries. In order to let more people get familiar with him, let's give you a detailed introduction. For his basic information here, you will not feel strange when you see him in the future.
Before we use the balance container, we need to know more knowledge points, because most of our friends are not very familiar with these problems. Today, we just take this opportunity to make a simple introduction. First of all, you need to know that the balance container is a kind of drum water level measuring device with clever structure and self compensation ability. It is also found that its main structure is the balance container, which is divided into single-chamber balance container and double-chamber balance container. The double-chamber balancing vessel has a circular funnel structure above the reference cup, dividing the whole balancing vessel into two parts. Because you want to use it, what you need to know is the density of saturated steam and saturated water (r/,r/). Here is a single-valued nonlinear function of the drum pressure P, which can be obtained by measuring the drum pressure. When working, the average water density R in the reference water column is usually calculated according to the water density at 50 ℃. However, the actual R has a large uncertainty, which is very different from the water density at 50 ℃, which is one of the main reasons for the measurement error. In addition, the reference water column temperature of this product in the single-chamber balance container is very different from the 50°C or 60°C corrected and compensated by DCs, which brings uncertain additional errors, and the error exceeds 100mm.
In addition, another good feature of the balance container is that because the error direction of the mica water level gauge is inconsistent with the error direction of the single-chamber balance container, it is impossible to ensure that the deviation between each water level gauge is within 30mm. At present, the mica water level gauge is standard, and then repaired by replacing the transmitter or DCS software correction. Under certain working conditions, the deviation can only be carried out within 30mm and a small numerical range, which is self-defeating. In this case, what you need to know is that the safe operation of the balance vessel and its boiler cannot be guaranteed. It can be seen that in the whole process and range, the deviation between the drum water level gauge can not be less than 30mm. Of course, this is mainly due to the inaccurate measurement of the drum water level, which leads to the long-term high water level operation of the drum, which reduces the working efficiency of the cyclone separator, makes the saturated steam carry too much water, and increases the fouling of the superheater and steam turbine. This also greatly reduces the working efficiency of the unit, accelerates the explosion and leakage of the superheater, and there is a great hidden danger of accidents. As the main product of our factory, thanks to the strong support of new and old customers, while ensuring the reliability of product quality, we also benefit our customers. If you have any technical problems related to the product, you can come here at any time to consult.
After the explanation of the above content, we also have a better understanding of the working principle of the balanced container. In fact, there are still many knowledge points about it. The next issue will bring more wonderful content. If you have time, you may wish to pay more attention to the website, so as not to miss the knowledge points related to him. I hope it can bring help to relevant people.
