1. Before starting: (1) Check the screen for damage and loosen it and replace it in time.
(2) Whether the fasteners are loose and tightened
2. At startup: (1) Pay attention to the presence or absence of abnormal noise
(2) Whether the three-phase current and the three-phase voltage are balanced
(3) Whether the vibration is abnormal
3. After application: clearing and cleansing after each application
At the beginning of the operation, check the anchor bolts at least once a day to avoid loosening. After regular inspection, the screen should be cleaned to get the best filtering effect. When cleaning the screen, it can be stopped without stopping. According to the different properties of the filter materials, the corresponding cleaning is adopted. Agent. If the mud can be washed with water, it is strictly forbidden to touch the hard object with a sharp object.
Note: It is strictly forbidden to wash the motor with water to prevent leakage when cleaning. If it is not used, please cut off the power supply. The dust of the vibration motor should be cleared in time to facilitate the heat dissipation of the vertical vibration motor.
Regular maintenance: Regular inspection of fine mesh and spring for fatigue and damage, whether the fuselage part can be damaged by vibration, vibrating screen machine operation for the first month, application of force arm, long wrench, fastening foot screw device bolts After two times, it should be inspected at least once a month, and the vibration motor should be inspected: the vibration motor, cable and connection installation should be stopped at least once every quarter.
The inspection method is as follows:
caveat! Cut and lock the power supply and give a warning sign before checking
The vibration motor should be switched off and locked and a warning sign should be given
Check the end cap for cracks and whether the end cap screws are unscrewed
Inspect the cable for damage, including cuts and wear, and replace it if it is damaged.
Check the grounding condition to ensure that the grounding resistance of the vibration motor housing does not exceed 0.1 ohms; ensure that the screw tightening torque on the grounding end meets the specified requirements; ensure that all coupling nut tightening torques on the terminal board meet the specified requirements; Too tight.
The main application industries of food vibrating screen are glucose powder, wheat starch, flour, yeast powder, rice flour, skim milk, soy sauce, salt, pollen, tofu, sweetener, rice bran, instant soup powder, powdered sugar, coarse sugar, fresh orange juice. , corn starch, pineapple juice, animal and plant gum, etc.
Virus Specimen Collection Tube
Inspection principle:
It can perform protein denaturation on fresh clinical virus samples to inactivate the virus, prevent secondary transmission of infection, and ensure the safety of transportation and testing personnel.
♣.Structural composition: Combination of cotton swab and transport medium (VTM).
♣. Product requirements:
The product should be airtight, avoid high temperature, avoid direct sunlight storage. It should be used in a clean, hygienic, pollution-free, and temperature-friendly environment.

♣. How to use
â‘ Before sampling, mark relevant information on the label of the sampling tube.
â‘¡. Sampling with the corresponding cotton swabs.
â‘¢ After the collection is completed, quickly put the cotton swab into the collection tube, break the part higher than the sampling tube, and tighten the tube cover.
â‘£. For the specific sampling method, please refer to the following:
a) Nasal swab Gently insert the sampling head into the nasal cavity, stop for a while and then slowly rotate to exit, immerse the collected specimen in the Xiangxiang solution, break the excess part and discard it, and tighten the sampling tube cover.
b) Pharyngeal swab: Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with the sampling head, immerse the collected specimen in the sampling solution, break off the excess part and discard it, and tighten the cap of the sampling tube.
c), Mycoplasma Chlamydia, Ureaplasma specimen collection
Male: Insert the sampling head into the urethra about 2cm and rotate, stay for a while and then exit, and immerse the collected specimen in the sampling solution.
Female: Wipe the mucus of the cervical orifice, insert the sampling tip into the cervical canal for 1-2 cm for sampling, immerse the collected specimen in the sampling solution, break off the excess part and discard it, and tighten the cap of the sampling tube.
♣. Precautions
1. After the virus is collected, the disposable sampling swab should be completely inserted into the preservation solution, so that the virus can be retained to the greatest extent possible.
â‘¡ The collected specimens must be sent for inspection in time.
â‘¢. It is forbidden to use products with damaged packaging and expired validity period to prevent pollution.
This single-use Virus Sampling Tube is used for in vitro diagnosis. It cannot be used for human or animal oral or external use. If swallowed, it may cause serious events; it is irritating to eyes and skin. If it is not splashed into the eyes, rinse with water.
