Explosion-proof wall practice drawings
The common methods of explosion-proof walls were reinforced concrete walls, brick walls with reinforcements, and sand-filled steel planks. For reference, the standard of Atlas 14J938 shows that the pressure value of the anti-explosion wall is greater than or equal to 400KPa. The design of the anti-explosion wall requires the use of fire-resistant materials that are not easy to burn. It should not be selected as the bearing wall of the house. It can be used as a reinforced brick wall. If there are special circumstances in the room next door (such as the presence of certain items, etc., which are not specified in detail), they need to be considered on a case-by-case basis. In terms of wall construction, materials with high strength, corrosion resistance, and explosion-proof properties should be used, such as reinforced concrete, fire-resistant bricks, and impact-resistant plates. The thickness of the reinforced brick wall shall be determined by the structural calculation, but it shall not be less than 240mm. The brick strength shall not be lower than MU75, and the mortar strength shall not be lower than M5. Along the height of the wall body, a horizontal steel bar of 3 × 6 - 10 length shall be arranged every 500mm. Both ends of the steel bar shall be bound or welding with the embedded steel bar of the reinforced concrete frame or bent column. There was also an explosion-proof wall structure consisting of steel keels, fiber cement composite steel plates, and rock wool. The fiber cement composite steel plates were made of two 0.5mm thick plated steel plates that were punched and squeezed onto 85mm thick fiber cement. There was also a 20-centimeter finished anti-explosion wall, which was made of double-sided single-layer fire-resistant board and reinforced with rock wool. During the construction process, the distance between the keels shall be 1200mm, and the installation method shall be bolted connection or welding (intermittent welding, the length of the welding spot shall be 50mm, and the distance shall be 100 - 110mm from the edge of the keels, and it shall be evenly distributed along the length of the steel plate). After the welding is completed, the welding slag shall be removed, and the steel surface shall be derusted. The base layer shall be painted without impurities, and it is strictly prohibited to miss coating, peel off and rust back. The explosion-proof wall can use a file or a grinder to remove the sharp edge produced by cutting the steel plate. The cut generally does not need to be anti-corrosive, but when removing the cut, avoid damaging the plated layer of the steel plate to prevent reducing the anti-corrosion property. The drill can be used for drilling, and the drill bit is made of high-strength stainless steel. The novel "Glittering Four Seasons" is equally exciting. Everyone is welcome to click and read it!

How to use the explosion-proof temperature controller for the reaction kettle
The usage of the explosion-proof temperature controller for the reactor is as follows: 1. ** Check before use ** - After opening the box, the appearance of the control instrument was checked to see if it was damaged or rusted due to transportation and storage problems. He opened the legs to check if the control instrument was level and if the movable parts were flexible. - According to the name of the connection on the back panel of the control instrument, connect the power supply, heater, motor power supply, temperature sensor, speed sensor and ground wire of the control instrument according to the terminal identification. After checking that there is no error, connect the power supply. 2. ** Temperature-adjustment ** - Follow the instructions of the thermometer. For the first use, it is recommended to set the program and directly use the self-tuning method to determine the P, I, and D parameters through the instrument self-tuning. However, the constant temperature time for the first use is relatively long, and the more accurate P, I, and D parameters can only be determined after three settings are completed. After that, if the same parameters were used, there was no need to start the self-tuning function again, and the temperature could be controlled more accurately. 3. ** Speed adjustment (if any)** - The stirring speed of the motor can be adjusted by the up and down keys of the speed governor. The required stirring speed can be achieved by referring to the speed displayed on the stirring speed display. 4. ** Running Operation ** - Carefully check if there are any abnormalities before normal operation. Do not open the back door during operation to prevent electric shock. - The measuring instruments should be regularly aligned to ensure accurate and reliable operation. The working environment of the equipment must meet the safety technical requirements. - For instruments that have been left unused for a long time and instruments that have been working in a humid environment for a long time, the overall insulation resistance should be measured irregularly. The overall resistance should not be less than 10 Mum. 5. ** Equipment stop operation (no mention of special stop operation for explosion-proof temperature controller of reaction kettle, refer to the general requirements for relevant equipment stop)** - First, turn off the heating or cooling system, then turn off the equipment's power supply, and finally deal with the equipment's water source and air source (if any). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
