Daily Maintenance And Maintenance Of Surgical Light

surgical light is an important medical device for surgery, which will directly affect the accuracy of the operation. The surgical lamp needs daily maintenance. Professionals will briefly introduce the maintenance and maintenance methods of surgical lights for everyone.

Surgery lamps are generally composed of multiple lamp heads, and bulbs are consumables. We check whether the surgical light bulb is still working normally every day. The correct inspection method is as follows: Put a white piece of paper in the working area of ​​the surgical light. An arc-shaped shadow appears in the area. Then the bulb is already in an abnormal working state and needs to be immediately Replace the lamp.

Check every day whether the disinfection handle of the surgical lamp is working properly, that is, whether it can be flexibly moved and the braking is accurate. The inspection method is as follows: If you can hear two “clicks” clearly during installation, it means that the installation is in place and the disinfection handle is in normal working state.

Use a weak alkaline solvent to scrub the appearance of the surgical shadowless lamp every day. Avoid using chlorine-containing lotions (corrosive metals) and alcohol solutions (corrosive plastics and paints).

Check the backup power system of the surgical lamp once a month, that is, whether the battery is used normally. The inspection method is as follows: cut off the connected 220V power supply and see if the backup power supply can start normally.

MATTERS NEEDING ATTENTION WHEN REPLACING PP WINDING FILTER

PP After long-term use, the PP winding filter element needs to be replaced, which can be solved by adding a rubber pad. When placing the filter element, you should also pay attention to putting the filter element straight. If you ca n’t screw the filter bottle, do n’t screw it hard. Unscrew the filter bottle and put the filter element back to the right to avoid damage to the filter element.

After the PP winding filter element is installed, it must be flushed before it can be connected to the subsequent system. The general flushing time must be guaranteed for more than 5 minutes. When is the filter element replaced? There is no rigid standard. The use time of the filter element will depend on the water quality. Generally, it is 6-8 months, but it is best not to exceed 1 year.

After selecting a good PP filter element, the correct installation and replacement of the filter element will ensure the normal operation of the filter element. Generally, the diameter of PP cotton filter is uniform and dense, and the highest precision can reach 1μm. It is mainly used to filter out impurities larger than 1μm in tap water. In addition, the filtering process of PP cotton filter is because the PP cotton filter belongs to the first stage of water purifier. In the filter element, more than 80% of the impurities will be filtered at this stage, and the more impurities filtered, the easier the filter element will be blocked. Therefore, the life span of PP cotton filter is very short, and it may take more than two months to replace the filter in areas with poor water quality.

General notes on Air Freight or Courier

Air Freight or Courier cargo packaging should be sturdy to prevent damage and leakage of contents during transportation; it should also prevent cargo damage and deterioration due to stacking, friction, vibration, and changes in air pressure and temperature, and prevent damage to operators and defaced aircraft , Ground equipment and other items.

Air Freight or Courier packages are not allowed to carry prohibited or restricted items, dangerous goods, valuables, confidential documents and materials. Therefore, goods that are precise, fragile, shock-proof, and pressure-resistant, and cannot be inverted must have corresponding packaging measures and instructions to prevent damage to the goods.

The shipper needs to indicate the departure station, arrival station, and the unit, name, and detailed address of the shipper and consignee on the package of each shipment. When the shipper uses the old package, he must remove the old signs and labels of the old package. The packaging of such special goods as live animals, live perishables, valuables, etc. all need to meet the specific requirements of air transport for the goods.

Possible misunderstandings about 5 axis cnc machining service

5 axis cnc machining service can generally be divided into four axes and five axes. Today we mainly talk about five axis machining centers. What is a five axis machining center? The five-axis machining center is five motion coordinate axes, two motion rotary axes and three linear motion coordinate axes. Generally, it can be divided into AC combined rotation axis and BC combined rotation axis according to the different installation positions of the two rotation movements. Many friends have a misunderstanding about the five-axis machining center.

5 axis cnc machining service is generally used as a high degree of automation and intelligent processing equipment for high-end manufacturing. Five-axis machining centers are suitable for machining free-form body parts, turbine parts and impellers on aircraft ships. The five-axis machine tool can not change the position of the workpiece on the machine tool, so as to perform related processing on different sides of the workpiece, which can greatly improve the processing efficiency of prismatic parts.

Many friends have a misunderstanding about the five-axis machining center. They believe that the five-axis machining center is based on the three-axis machining center and adds two rotary axes. The two rotary axes first fix the cutting tool in an inclined position, and then move and process by the feed axes X, Y, and Z. But this is not really a five-axis machining center. The 5-axis machining center has a tool point following function, which can ensure that the cutting point of the tool contacts the surface of the part without changing any parameters to avoid cutting pits.

What is Thermoformed Packaging for?

Thermoformed Packaging is to heat and soften thermoplastic rigid plastic sheets such as polyvinyl chloride and polyvinyl chloride, and then use vacuum suction and punching to form the plastic sheet into a container for the material, and then cool and shape it, then load it. materials. A layer of aluminum foil coated with an adhesive and cellophane, composite materials, etc. are then heat sealed together, and then cut to complete the packaging. This series of working packaging machines is called thermoforming packaging machines.

Thermoformed Packaging's packaging method has now been developed to package any material in any form. Thermoformed containers are not just small blister-shaped, but larger trays, cups, bowls, and used to package food, daily necessities, and electrical components. Wait. This kind of packaging has the advantages of light weight, good sealability, strong adaptability, transparency and visibility, and no additional buffer material for packing, which is convenient for sales and consumption, so it has developed rapidly in recent years. In line with this, thermoforming packaging machines have also developed rapidly in recent years.
