First, the operation method
1. Check before use: After the machine is installed, turn on the power, test the three-phase motor, ensure the correct running direction, ensure the pressure and flow of the compressed air, check whether the motor, bearing, etc. need to add lubricating oil, and strictly prohibit oil-free operation. The machine can be started normally, and the fasteners of each part are observed to be loose. After the operation of each part is stable, it can be used normally.
2. Check if the safety function is normal.
3, before starting the double check that everything there was reservoir material, presence or absence of the link plates stuck, if there is debris on the conveyor belt, whether a cap, water, electricity, gas supply is turned on within the reservoir cover rail, each to be After the condition is ready, close the main power supply QF, the power indicator light is on, the fault indicator light and the emergency stop indicator light are off, then the start condition is available. Press the control box and the touch screen switch to start the operation and enter the external wash and rinse. Filling fully automatic working mode, stop pressing the stop button at the filling station and control box, and turn off the main power of the control cabinet after stopping.
Second, the use of security rules
1. There is no foreign matter (such as tools, rags, etc.) in the filling machine equipment;
2. The filling machine is not allowed to have abnormal noise and vibration. If it should be stopped immediately, check the reason. It is absolutely impossible to make various adjustments to the rotating parts when the machine is running;
3, all protective materials should be safe and reliable, it is strictly prohibited to wear clothing that may be caught by moving parts (such as scarves, bracelets, watches, etc.); long hair, should wear a hair hood;
4. It is forbidden to clean the electrical unit with water and other liquids;
5. Wear overalls, gloves, glasses, etc. during cleaning to prevent strong acid and alkali corrosion;
6. When the machine is running, it must be monitored by someone. Do not use tools or other objects to access the machine.
7. It is strictly forbidden for personnel unrelated to operation and maintenance to access the equipment to prevent work injuries.
Third, maintenance and maintenance
1. Regular inspection and maintenance: The motor, bearing, conveyor belt, chain, pneumatic components such as cylinders, solenoid valves, speed control valves and electrical parts should be inspected monthly. The inspection method can be checked by manual adjustment to check the quality and reliability of the operation. The cylinder and the electromagnetic reversing valve mainly check whether there is air leakage and jamming. The solenoid valve can be manually forced to determine whether the electromagnetic coil is burnt and the valve is blocked. Check the input and output signal indicators to check whether the switch components are damaged, whether the line is disconnected, and whether the output components are working properly.
2, daily inspection and maintenance: every shift should routinely check the filling valve, double side sealing system, motor, conveyor belt, chain is normal operation, whether there is abnormal vibration, abnormal sound; loose fasteners in time Tightening. Whether the cooling and lubrication system is abnormal, whether there is abnormal overheating and discoloration, and timely add the required grade of lubricating oil.
Fourth, matters needing attention
1. The motor and casing must be grounded, and the neutral and ground wires must be separated.
2. The incoming power of the machine must be introduced through the leakage switch. It is strictly forbidden to change the line and the private connection. It is strictly forbidden to place any sundries in the electric cabinet.
3, pneumatic components require the addition of pneumatic special lubricants to extend the service life of cylinders and electromagnetic reversing valves;
4. The pump is strictly prohibited from working without water. The supply of cleaning water is guaranteed during the operation to flush the spilled material.
Five, equipment cleaning requirements
1. Clean the valves, spouts, pipes, conveyor belts and individual liquid storage tanks of the equipment before and after work every day;
2. The operator should record the disinfection and cleaning process and save it for review.
Urine analyzer is an automated instrument for determining certain chemical components in urine. It is an important tool for automated urine inspection in medical laboratories. This instrument has the advantages of simple and fast operation. However, improper use of urine analyzers and many intermediate links and influencing factors directly affect the accuracy of automated analysis results, which will not only cause errors in experimental results, but even delay diagnosis. Therefore, operators are required to understand the principles, performance and precautions of automated instruments. And the knowledge of influencing factors and other aspects are fully understood, and the correct use of automated instruments can make the results obtained by the urine analyzer more reliable and accurate.
application
In the 1950s, a single dry chemical test strip method was used to measure protein and glucose in urine, and the changes in the color of the test strip were observed with the naked eye and compared with the standard plate to obtain the corresponding values. In the 1980s, due to the high development and widespread use of computer technology, automated urine analyzers also developed rapidly, gradually developing from semi-automatic to fully-automated. Urine analyzers are often divided into two categories according to the test items: â‘ 8-11 screening combined urine test strips mainly used for newly diagnosed patients and health examinations. The eight test items included protein, glucose, PH, ketone bodies, bilirubin, urobilinogen, red blood cells (occult blood) and nitrite; in addition to the above eight tests, urine leukocyte test was added to the nine test items. On the basis of 9 of the 10 urine analyzer testing items, the urine specific density test was added. 11 testing items have added vitamin C testing. â‘¡It is mainly used for the observation of the curative effect of the diagnosed diseases, such as the combination test strip of PH, protein and occult blood (red blood cells) for kidney disease; the combination test strip of PH, sugar and ketone body for diabetes; the combination of bilirubin and urobilinogen for liver disease test tape.
principle
This type of instrument is generally controlled by a microcomputer, and the color change on the test strip is measured semi-quantitatively by using a spherical integrator to receive dual-wavelength reflected light. There are several reagent pads containing various reagents on the reagent strip, each of which reacts independently with the corresponding components in the urine, and displays different colors. The depth of the color is proportional to a certain component in the urine, and there is another in the reagent strip" Compensation pad", as the urine background color, compensates for the errors caused by colored urine and instrument changes.
Put the reagent strip with urine adsorbed in the colorimetric tank of the instrument, and the various reagent pads that have produced chemical reactions on the reagent strip are illuminated by the light source, and the reflected light is received by the spherical analyzer, and the photocell of the spherical analyzer is reflected. Irradiate with dual-wavelength light (measurement light passing through the filter and a reference light), and the selection of each wavelength is determined by the detection item.
The instrument automatically calculates the reflectance according to the following formula, and then compares it with the standard curve, and automatically finds and prints the corresponding results of various components. If the content of a certain component in the urine is high, the reflected light of the corresponding reagent pad is dark, otherwise it is strong.
Reflectance fraction: R(%)=Tm.Cs/TsCm×100%
In the formula, R(%) is the reflectivity; Tm is the reflection intensity of the reagent pad to the measurement wavelength; Ts is the reflection intensity of the reagent pad to the reference wavelength; Cm is the reflection intensity of the calibration pad to the measurement defect length; Cs is the calibration pair. Reflection intensity at the reference wavelength.
