Because vaccines, drugs, etc., are related to the safety of vaccination, how do vaccines are sent to vaccination agencies from the time the vaccines are released to storage? The entire transportation process in the middle has attracted the attention of the society, parents, and school. As long as there is a slight mistake in one of the links, the quality of vaccines and medicines may be questioned, and the health of children cannot be guaranteed.
The control of the temperature during the transport of the vaccine is very important. Before the vaccine is put into the refrigerated truck , it is necessary to put the temperature monitor in the car. This can guarantee that once the temperature inside the cabin becomes abnormal, it can be quickly monitored. . In addition, before the vaccine is installed on the vehicle, it must be ensured that the temperature inside the cabin is controlled between 2°C and 8°C.
In the process of storage and transportation, temperature is the lifeline of quality assurance, and it is not advisable to leave the cold chain of the vaccine too long. The transportation must be fast and the handling time should be shortened as much as possible.
In the cold storage of the vaccine, there is a chilly atmosphere. Four rows of tall shelves contain various types of vaccines for immunization programs. There are four refrigerating evaporators in the four corners of the ceiling of the refrigerator to keep the temperature of the refrigerator balanced. The inside of the warehouse is a two-way power supply and also has a generator. "Even if there is a power outage, the temperature of the refrigerator can be guaranteed.
Different from ordinary trucks, the cooling equipment for professional vaccine refrigerators is separated from the air-conditioning in the cab. The refrigerated air circulates independently inside the container. There is an air diversion tank at the bottom of the container to ensure that the vaccine is not kept close to the bottom of the container. The temperature is increased to ensure that the temperature in each position of the container can be stabilized at 2-8°C.
The transportation of vaccines has a direct bearing on people’s health. Therefore, it must strictly comply with relevant laws and regulations, strengthen vaccine supervision, standardize inoculation activities, improve and standardize the construction of preventive vaccination service networks, firmly guarantee the quality and safety of vaccination services, and consolidate and improve national immunity. Plan the vaccination rate and raise the level of vaccination. Build a more rational vaccine safety network and really build an "immune barrier" for vaccination.
Compact machining center is a type of machining center that is further improved and derived from the structure of a vertical machining center. With the development of society, modern people's pace of life is getting faster and their work efficiency is getting higher. In the field of metal cutting, basic processing functions such as drilling, tapping, and milling are no longer problematic on vertical Cnc Milling Machines. However, with the changing times, such requirements are gradually unable to meet the higher requirements of customers. People are looking for faster, higher precision, and more environmentally friendly processing equipment, and compact Machining Centers are born to meet these needs.
In China, this type of compact machining center is usually called a drilling tapping center. Its characteristics are compact machine structure and high production efficiency. Typically, compact machining centers have the following characteristics:
1. Compact structure, small appearance, and small footprint. The ground space is reduced by 21% compared to Vertical Machining Centers. More machines can be placed in the same venue and space. Generally, manual vehicle insertion can be used for transportation, and it can be accessed by the factory freight elevator for easy transportation to the floor type workshop. The maximum travel of the machine tool on the X-axis generally does not exceed 700mm, and on the Y-axis it does not exceed 400mm. Very suitable for processing small parts such as 3G industry, electronics industry, medical devices, etc. Of course, as customer demand develops, the travel of the X-axis has also expanded to larger specifications for more customers to choose from.2. The displacement speed is fast, and the machine tool can move at least 48m/min and up to 60m/min.
3. The spindle adopts a BT30 20000/24000rpm spindle, and the normal spindle speed is at least 10000rpm or above, usually 12000rpm or even higher. Therefore, the speed has also been relatively increased during drilling and tooth tapping.
4. Adopting a flying saucer type tool magazine, its characteristic is that the tool magazine is located on the spindle, which reduces the tool changing path and greatly improves the tool changing speed during tool changing. The fastest tool changing time is 1.2 seconds. Like LEYO compact machining centers generally use servo tool libraries, which improve the speed and efficiency of tool changing compared to ordinary tool libraries.
5. It is more energy-efficient and environmentally friendly. Drilling machines have a processing efficiency twice that of vertical machining centers, and the more efficient they are, the more environmentally friendly they are. Energy consumption is reduced by 70% compared to vertical machining centers.
6. It can achieve a higher degree of automation in production. If combined with the use of robots and real-time online diagnosis through the Internet, continuous production can be achieved 24 hours without human supervision, further improving production efficiency and automation.
Therefore, compact machining centers are very suitable for factories to process small and large quantities of spare parts. A factory with very high requirements for production efficiency.
