solve.
We have developed a portable dry, automatic control circuit and high-voltage test based on the principle of combining peacetime and warfare. Full function. Simple operation and features. On-site maintenance of line symbols. 1 Connect to empty automatically. Warm and dry, note the exhaust. It is also possible to perform tests on instruments that are used in refrigerators.
The equipment will also be used to station medical units, line machines will be replaced with field machines, oil change, Ning dry oil soaked in high pressure generators, and the combined machine head line, high pressure line, high pressure Rectifiers, in the same way, use test equipment to verify the trueness of transformers and transformer oils. Because of the exercise, the wartime field hospitals and the rear hospitals are relatively mobile, and the environment is rather harsh. The complex geomorphology of the line tube is a fragile glass device, and it is easily broken in the cold and the high-voltage generator leaks during the movement. The oil enters the air bubble and is discharged by moisture. The wire is easy to break down. Portable Field Vacuum Filling Equipment Foot Large, medium, and small hospitals + Indispensable inspection and inspection set-ups are also necessary for the hospital maintenance organization. The structure of the equipment: The principle of vacuum pumping is 38. The output pressure is 1051, and the one-way electric power is 370. . The vacuum box has a diameter of 43 and a length of 60 hours. It is equipped with an oil inlet vacuum vacuum pipe anti-air 1 and an infrared heating temperature sensor. Observation window storage door and auxiliary maintenance oil worktable facilitate folding. When the high-pressure test fails and the line tube fails, it firstly undergoes a visual inspection, a low-voltage check, and a focused filament ignition. If the filament is ignited, the cheek is good. Seven evapotranspiration of the glass wall, island pressure check will be added on both sides of the ball cathode and anode 0 government 60 high-pressure non-glow discharge description is normal, and vice versa for pipe maintenance. The filaments and the high-voltage primary voltage are respectively added to the combined head, the filament is ignited normally, and then the primary high voltage is applied from low to high, the initial current is increased sharply, and the line appears to be bright. Description line pipe Received date 20,212 http protection can not be ignored when the protection measures Xu Shuzhou Jinan People's Hospital, Jinan, Shandong 250101 å…€ inspection is safe, this is well known, and safety does not mean no damage. This is easily overlooked by people. In response to this question we have conducted some discussion.
1 It is also the line that shines on the human body to examine apricots. It seems that the exams and the normal father line examinations are used. The line is not markedly differentiated in terms of quantity and quality, and can be converted to blood.
While the general line inspection 6 is a wide beam, the line is wider in the same beam than the narrow beam, and the energy of the line is large. This is because there are fewer elbows in the narrow beam and the wide beam. 2, the inspection, the hard line quality, the absorption of less absorption; and ordinary, linear soft absorption and more. 3, when passing through the body's parent line during inspections; received by a highly sensitive detector, several conversions during the imaging process, not only, the line energy loss is small and there is amplification, and ordinary, line inspection, receiving through the human body 1 line can be a screen. Right, the energy loss of the line is not only great, but also the conversion rate is low. Such a coincidence of checking apricots requires a greater amount of radiation than an oral inspection. In the 401 machine, the filtering requirement of the line tube is higher than that of the ordinary line symbol, and the longer wavelength cord is absorbed. Flash this, the line where the tube occurs. It is almost seen as a single high energy beam. Remove the soft line from the skin, but normal, line inspection can not be achieved.
Due to the above reasons, the human body is multi-layered and the scan is still safe, but safety does not mean no damage.
The Importance of Protection According to the new report of the International Protection Committee, the date of receipt 200210 will classify the biological effects of radiation into two types: random effects and non-machine effects. The random effect means that there is no threshold for the biological effect, and any tiny dose may also cause carcinogenic effects and genetic effects.
Only the probability of occurrence is very small and self, and there may be dose thresholds instead of random effects. The degree of damage to the human body changes with the dose, so the protection of the 01 inspection is very important and should not be ignored.
Protective measures: The purpose of radiation prevention is to prevent harmful non-random effects and limit the incidence of random effects to acceptable levels. In addition to the specific protective measures, Ding Machine itself and the inherent protection of the engine room as individuals pay attention to the following several 1 to strengthen the awareness of protection to do radiation practice is positive.
Simplified rubbing also has damage to the human body. Therefore, it is really necessary to conduct an inspection to check and avoid unnecessary irradiation. , Do a good job of preparatory work before the scan, and obtain patient cooperation, so as to achieve the desired effect of the 01 inspection and reduce unnecessary rescans. 3 D scan, 1 for humans and accompany people to leave, scanning room, if necessary, put on protective clothing or as far as possible from the bulb to describe 4 in the description, try to narrow the scan field. Less than 1 can do more than sweep, can sweep + + to sweep. Can not, strong + enhance, choose the right conditions. 5 contrast, strong scan try to use automatic pressure syringe, the staff can leave when scanning. 6 Strive to improve the scanning technology and diagnostic level to prevent rescans. 7 pairs of pregnant women and children as far as possible outside the description of the period of coverage of the protection of the detection of relevant lines, the occurrence of a timely manner to solve the vacuum + to or; 1 Le silicon pillars have breakdown. Or short-circuit high-voltage package.
The other high-voltage generator fault discrimination is similar to that of the combined nose. The above maintenance work is carried out on the oil workbench. The oil workbench is placed on the top to maintain the vacuum and warm the oil, and the workbench enters the side of the crucible. Place the ball in the vacuum box and close the door to cool it. The lower temperature limit is 65, and the upper limit is 75. Heat! 21 then turn on the vacuum pump, the pressure reaches 0.1 time to open the injection valve to inject the transformer oil into the pipe, when the injection of oil is complete, close the fuel injection valve 20 to stop the vacuum, open the air release valve, when the vacuum pressure points to 0, the ball exhaust package, The whole working time is about 3, if the time is longer, the effect is better. The same is true for the combined heads. For large-scale, high-voltage generator line fault repair is mainly reflected in the vacuum drying and immersion oil of the high-voltage wire package. The fault line Bao Xun, unloading and then will be empty, dry dip good wire package quickly installed, put 汕ç˜, between 2131. Repeated test from low to high power sand, the above effect is very good, to achieve a rapid emergency, in The exercise battlefield is very suitable and is an indispensable maintenance equipment for the field health equipment maintenance detachment.
