Improved Vacuum Machine
The vacuum system in the bulk drug workshop of Jinxi Pharmaceutical Factory has 13 liquid ring pumps and Roots vacuum units. Due to operational problems, the blades of the vacuum units are often damaged, which affects the normal production of the workshop.
In response to this situation, Wu Guangjun, the monitor of the electrical work class of Jinxi Factory, went to the scene many times to observe and finally found the reason-when the circulating pump was stopped, the pump often stopped but did not vent, so the blades of the circulating pump would be subjected to two opposite forces, resulting in damage.
After finding out the reason, the electronie class staff designed a reasonable and feasible control system together. The venting operation will not require human control and will be automatically controlled by the solenoid valve control system. The workshop operator normally starts the vacuum water ring pump. After the vacuum is used, press the stop button, the circulating pump will not stop immediately, and the solenoid valve will open at the same time; when the pointer of the vacuum pressure gauge reaches 0.04 MPa, the circulating pump will stop; When the pointer reaches 0 MPa, the solenoid valve is closed. For the consideration of the unexpected situation, the emergency stop button is also installed in the secondary circuit, which can make the motor stop normally when the electric contact vacuum gauge and the solenoid valve fail.
At present, all the vacuum units in workshop 13 have been technically reformed. Through the test machine, they can meet the requirement of automatic shutdown after breaking the air, thus saving the cost and providing guarantee for the production of bulk drugs. (Zhu Guoping)

The notice requires all subordinate units of the company to attach great importance to the work of production safety in summer, and all production and business units should hold a special meeting on production safety in summer. According to the characteristics of production in summer, they should focus on safety risk analysis for mines, outdoor operations and high-temperature posts, and implement control measures to avoid the occurrence of safety accidents such as scalding, heatstroke and electric shock. In order to further strengthen the safety production management in the high temperature season, the notice requires the main person in charge of each production and business unit to lead a team to conduct a comprehensive inspection of the production and business premises according to the characteristics of summer production; strengthen the daily safety production inspection of key posts and special posts; timely rectify the found unsafe behaviors and hidden dangers; Strengthen the management of the storage and use of flammable, explosive, dangerous chemicals and drugs; cooling measures shall be taken for the space exceeding the storage temperature limit of articles. If it is found that the electrical equipment circuit and exhaust fan circuit are aged and damaged, replace them in time and keep the grounding wire in good condition. Do a good job in checking the fire pool, pipeline water pressure and fire extinguishing equipment to ensure that the fire fighting facilities are sensitive, intact and reliable. The high temperature in summer is also a period of frequent occurrence of heatstroke and other diseases. The notice requires all units to do a good job in heatstroke prevention and cooling, implement various relevant measures, and equip necessary cooling facilities or materials such as fans, air conditioners, ice cubes and other cooling facilities or materials according to the conditions of the production site; do a good job in the distribution of heatstroke prevention drugs, supplies and cool drinks in workshops, warehouses, construction sites and other production lines; strengthen canteen management to prevent food poisoning.
