What are the design requirements of the high-pressure reactor?
The design requirements of the high-pressure reaction device (taking the high-pressure reaction kettle as an example) are as follows: ** 1. Determination of parameters ** 1. ** Pressure and temperature design ** - If the user provided the highest working pressure and working temperature, the type and form of the discharge device should be determined according to the material nature, and then the design pressure and design temperature of the reactor should be determined according to the relevant requirements of the high-pressure discharge device in the annex of the Steel Pressure Vessel. 2. ** Volume of high-pressure reactor ** - The volume is divided into full volume and effective volume. Usually, the user provides the effective volume. The staff must determine the material filling factor according to the safety production standards and control it to 0.5 - 0.95. For the reaction kettle with a flange-structure container, the material filling height cannot be higher than the sealing surface of the flange-structure container. 3. ** Type of shaft seal confirmed ** ** 2. Satisfy the requirements for production ** The high-pressure reactor used in the refinery should be able to withstand the pressure and temperature required in the production process, and have the specifications and structure required for the production process. ** 3. In terms of reliability ** 1. The chemical production materials were corrosive, toxic, flammable, explosive, and so on. When the reactor worked, it stored energy inside. Once it was destroyed, the energy would be released in a short period of time, causing damage. Therefore, it was necessary to ensure reliable exchange operation. 2. To ensure the designed service life. Since the chemical raw materials have corrosive effects on the shell material of the reactor equipment, additional corrosion allowance should be considered during the design to meet the service life requirements. ** 4. In terms of convenience ** The manufacturing, inspection, installation, operation, and maintenance must be convenient. The quality of equipment with simple structure, easy manufacturing and flaw detection is easy to guarantee, and it is easy to find and eliminate defects exceeding the standard. For test vessels whose top cover needs to be disassembled frequently, a quick-disassembled sealing structure should be adopted. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Experimental Principle of Hopkinson Pressure Bar
The Hopkinson pressure bar experiment used the Hopkinson bar device to test the dynamic mechanical properties of materials. The strain rate range was 10 <2>- 10 <2> s <2>. The principle was as follows: When the impact rod (bullet) in the gun chamber was ejected into the input rod at a certain speed, an incident pulse would be generated in the input rod. The stress wave would reach the test piece through the elastic input rod, and the test piece would produce high-speed distortion under the effect of the stress pulse. When the stress wave passed through the test piece, it produced a reflected pulse at the same time. The reflected pulse entered the elastic input rod, and the projected pulse entered the output rod. The speedometer could obtain the bullet's speed, and the strain gauge attached to the elastic rod could record the strain pulse, which could then be used to calculate the dynamic stress and strain parameters of the material. According to the incident wave, reflected wave, transmitted wave, and one-dimensional stress wave theory measured by the resistance strain gauge attached to the compression bar, the average strain rate, average strain, average stress, and other parameters of the sample could be obtained through specific calculation formulas. Then, the dynamic compression mechanical behavior of the material could be calculated and studied. Harry Potter and the Order of the Phoenix is not enough. Please click to read the novel!
Mechanical Principle of Shaper Course Design
The purpose of the course was to design, analyze, and perform dynamic and static analysis on the main mechanisms of machinery (such as connecting rod mechanisms, gear mechanisms, and so on), as well as to design the gears and gears according to the work requirements of the given machine. 1. ** Purpose * - Deepen students 'theoretical knowledge and cultivate their ability to solve practical problems independently. - To let the students have a complete concept of the analysis and design of mechanical kinematics and dynamics. - Students were trained to draw up a sports plan, and they were equipped with the ability to design, select, combine, and determine the transmission plan. - To improve the students 'ability to calculate, draw, express, use computers, and access technical information. 2. ** Quest Requirements ** - According to the design task, draw the necessary drawings and write the instructions. - The main body of the shapers must be designed, and the dynamic and static analysis must be done. For example, in the aspect of motion analysis, it was necessary to analyze the speed and acceleration of different positions of the guide rod mechanism. In the aspect of dynamic static analysis, it was necessary to calculate the inertia force, the dynamic static analysis of the rod group, and the calculation of the equilibrium moment. 3. ** Design Method ** - It mainly used the graphic method, which was clear and intuitive. Of course, there was also an analytical method, which was more accurate. During the design process, the actual working requirements of the shapers needed to be considered. For example, in order to improve work efficiency, the planer must be quickly retracted during the empty return trip (the travel speed ratio coefficient is about 1.4); the speed of the planer must be stable during the working stroke, and the cutting stage should be approximately uniform. At the same time, factors such as the stroke of the planer, cutting resistance, and motor speed should also be considered. For example, the speed of the cranks is 72r/min, the stroke of the planer is about 300mm, and the cutting resistance is about 8000N. When the planer is working, the motor is driven by the belt and the gear to drive the cranks and the cam-fixed on it. The guide rod mechanism drives the planer head and the planer knife to do a reciprocation. When the planer head goes to the right, it is the working stroke, and when it goes to the left, it is the idle stroke. The idle stroke time is used to drive the screw mechanism through the cam-fixed four-bar mechanism and the ratchets to make the workbench and the work piece do a feeding movement. In addition, due to the large change in the force on the plow head during the entire motion cycle, it would affect the uniform operation of the main shaft. Therefore, it was necessary to install a flywheels to reduce the speed fluctuation of the main shaft, improve the cutting quality, and reduce the capacity of the motor.
High pressure 100 low pressure 80 dizziness
Blood pressure of 100/80mm <anno data-annotation-id ="00000000 - 4110 - 4000 - 9999 - 9999 - 9999999999999"> hmmm </anno> was within the normal range.

Low pressure and high pressure, no medicine is recommended
Whether or not to take medicine for low or high pressure depended on the specific situation. If it was a middle-aged or young person with good elasticity of blood vessels, low blood pressure of less than 100 mm <anno data-annotation-id ="0000010c-400a-400a-400a-800a-900000000000"> hPa </anno>, and no other serious diseases such as diabetes, cardiovascular disease, stroke, and other diseases, and at the same time, there were also adverse factors that could be improved, such as being obese or overweight, lack of exercise, unhealthy diet, high psychological stress, mental tension, and lack of sleep, then they could first reduce blood pressure through healthy lifestyle intervention, such as weight loss, smoking and alcohol restriction, and establishing healthy eating habits.(For example, a low-salt diet, no more than 5 grams of salt intake per day, appropriate replenishment of potassium), reduce the intake of strong tea and coffee, strengthen regular exercise, relax and improve sleep conditions, etc. However, if the low pressure has exceeded 100 mm of mercury, or if the low pressure does not exceed 100 mm of mercury but also suffers from diseases such as diabetes, chronic kidney disease, cardiovascular disease, stroke, or after 3 - 6 months of healthy lifestyle intervention, the low pressure has not fallen back to 90 mm of mercury, or if you cannot adhere to healthy lifestyle intervention, then you need to consider medication.

Low pressure 107, high pressure 155, need to take medicine
If the low pressure is 107 mm of mercury and the high pressure is 155 mm of mercury, this has already reached the standard of high blood pressure (a blood pressure of 140 - 159 mm of mercury and/or a blood pressure of 90 - 99 mm of mercury is considered to be Grade 1 high blood pressure, and a blood pressure of 160 mm of mercury and above or a blood pressure of 100 mm of mercury and above is considered to be Grade 2 high blood pressure). Generally speaking, this kind of situation might require medication, but other factors needed to be considered. First of all, if it was the first time that the blood pressure was found to be elevated, it should be ruled out whether there were inaccurate measurements, such as whether there was a full bladder (holding urine), sitting posture (sitting sideways), arms hanging in the air or raised during the measurement, cuffs on clothes, cuffs too small and tight, crossed legs (crossing legs), talking during the measurement, etc., which may cause the blood pressure reading to be high. If it was because of these factors that caused the blood pressure to rise, the blood pressure might return to normal after correction, so there was no need to take medicine. Secondly, if people with pre-high blood pressure (120 - 139 mm <anno data-annotation-id ="000000110 - 400a-411a-425a-800a-9999999999999"> contractile blood pressure </anno> and/or 80 - 89 mm </anno> dilated blood pressure </anno>) found that their blood pressure had reached this value for the first time and had not undergone lifestyle adjustment before, they could try lifestyle adjustment for 1 - 3 months, including low-salt and low-fat diet, smoking and alcohol restriction, weight loss, not staying up late, not tired, maintaining a happy mood, etc., and monitor their blood pressure regularly. If their blood pressure still did not drop, they needed to consider medication. However, if the blood pressure is still at this level after lifestyle adjustment, or if it is accompanied by target organ damage (such as heart, brain, kidney and other organ damage), diabetes, cardiovascular disease, etc., it is usually necessary to take anti-inflammatory drugs under the guidance of a doctor. In addition, special types of high blood pressure such as white coat high blood pressure (high blood pressure when checked in the hospital, but normal blood pressure when measured at home, and no target organ damage was found) did not need to take drugs, but if it was true high blood pressure (high blood pressure measured at home and in the hospital), medication should be considered. It is recommended to go to a regular hospital to see a doctor, determine the type of high blood pressure, and use the medicine reasonably according to the doctor's advice. Do not blindly take the medicine on your own. While waiting for the TV series, you can also click on the link below to read the classic original work of "Dafeng Nightwatchman"!
What's the high temperature reactor for?
The high-temperature reaction kettle was a container used for chemical and chemical reactions. When these reactions were carried out, it could be used to measure temperature, add noble gases, measure pressure, PH value, conductivity, oxide-reduction potential, and other precise chemical synthesis reactions. Its heating power was 300W-500W, and there were many heating methods, such as electric heating (including jacket electric heating and zero-distance electric heating) and circulating heating. Among them, the jacket electric heating reaction kettle can heat the material to 260 degrees Celsius, and the zero-distance electric heating can heat the material in the kettle to 400 degrees Celsius. The working temperature is generally below 400 degrees Celsius, and the working pressure is 6 Pa. The valve and pipe fitting are imported from Germany, the interface is standard configuration, and the stirring speed and temperature are displayed in numbers.(0 - 1500km/h, speed accuracy of +/-1km/h), the patent inserted needle type K sensor (working temperature below 400 ° C, display accuracy of +/-1 ° C), standard stirring device, reaction kettle body, electric heating fiber furnace, inserted needle type K sensor, etc., can also be filled with an noble gas to protect the reagent from direct contact with the air, can insert a variety of sensors to ensure accurate measurement of relevant data. It also had some technical highlights, such as the ability to realize a variety of serial experiments, the ability to connect to a computer through the RS232 communication interface to print and display the historical values and actual curves required by the user, and the ability to monitor the entire system in real time through software. The selection of the high temperature reaction kettle oil temperature machine needs to consider the size of the reaction kettle, temperature requirements, whether it needs to be cooled, the volume and interface size of the reaction kettle jacket, the pressure resistance of the reaction kettle, and other factors. The heat transfer oil is heated to maintain the working temperature in the kettle. The duration depends on the production process. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
