Pressure transmitters in the paper industry play different roles at different stages

Pressure transmitters in the paper industry play different roles at different stages

2016-10-09

Pressure transmitter is a commonly used flow measuring instrument, which is widely used in various industries. In the paper industry, pressure transmitter is also one of the indispensable parts. It is almost different in the paper industry. Different types of pressure transmitters are used in the stages. The pressure transmitter is the most frequently used in the entire paper industry, so what is the role of the pressure transmitter in each of the different stages? How does it work? Next, the pressure transmitter manufacturer will come to reveal the answer to everyone!     1. The pressure transmitter is used in the material preparation section.The pressure transmitter is mainly involved in the flow measurement of refining, water and acid or alkali in the pulping process. Generally, the temperature of the slurry after mechanical grinding should reach 80°C. However, when wood or grass materials are used as raw materials for pulping, a cooking process is usually required. Since the cooking liquid is generally alkaline, the lining of the pressure transmitter is mostly high temperature resistant PTFE, and the structure is split. The electrode material must have corrosion resistance, so you need to choose carefully when choosing the electrode material.   2. The pressure transmitter is used in the screening and bleaching section.There are about five kinds of pulp (chemical pulp, deinked pulp, CTMP, mechanical pulp, and damaged liquid pulp) from each material preparation workshop into the papermaking workshop to participate in the pulping process. Here, the temperature of the machine pulp and CTMP pulp is as high as 50 to 80°C, and the pressure transmitter lining material should be PFA or PTEE preferentially.   　　In order to obtain paper of different quality, the slurry ratio can be completed by using different slurry ratio concentrations. However, if the finished product is unqualified due to the fine ultra-tolerance of a slurry, it will cause great losses to the manufacturer. Therefore, the manufacturer pays special attention to this link. Each of the pipelines participating in the proportioning is equipped with a pressure transmitter to measure the instantaneous and total flow into the slurry distribution main pipe. At the same time, the online concentration is installed at the lower end of the slurry pipe Calculated to detect the effect of slurry preparation. If there is a deviation from the expected, adjust the corresponding slurry flow by adjusting the opening of the valve. This requires high accuracy requirements for pressure transmitters, as well as good repeatability and fast dynamic response.   　　Pressure transmitters generally use PTFE or other fluoroplastic linings in the papermaking field: electrodes are selected according to the acidity and alkalinity of the liquid. When selecting electrodes or lining materials, if there is a mismatch, the sensor may not operate normally, so it is very important to select a suitable pressure transmitter in the paper industry. In addition, the factors that affect the accuracy of the sensor include dissatisfied pipes, insufficient length of straight pipes, misalignment during small-diameter installations, and so on.   　　In addition to the above-mentioned paper preparation section and screening and bleaching section as representatives, it is also necessary to select a suitable pressure transmitter from the analysis of the environment of each section, etc., in order to reduce the error of the measurement process and ensure the normal operation of the sensor. The produced paper meets the predetermined requirements.

Problems to be solved in the localization of fire pressure sensors

2016-09-28

Fire pressure sensors are the most widely used products in modern industrial production, and they are widely used in many industries. However, a large part of the domestic demand for pressure sensors still relies on imports, especially for precision pressure measurement occasions. In the past few years, domestic manufacturers have also continued to improve their technology, product performance has been improved, and the phenomenon of uneven quality has also appeared. On the other hand, it has also led to a reduction in the price of foreign products, but they are still very expensive compared with domestic products.
