Rabies Vaccine (Vero Cell) for Human Use
The first company develops and employs the technology of microcarrier bioreactor for production of Rabies Vaccine (Vero Cell) for Human Use in China. The culturing process has good repeatability, the product shows reliable quality and in reasonable stability and has the comparable effect with lyophilized formulation.

To adjust the valve clearance at random, most operators do not use special tools for inspection, but judge the size of the valve clearance by shaking the feeling of the valve rocker arm. This will affect the work of the diesel engine, lighter fuel consumption, and engine power. In severe cases, the piston and the valve collide with each other, and even lead to major failures such as rotted pistons, distorted connecting rods, broken crankshafts, and hitting cylinders.
Do not clean the carbon deposit of the exhaust pipe for a long time Most operators ignore the maintenance of the exhaust pipe of the locomotive. They do not clean the carbon deposit of the exhaust pipe for a long time. As a result, the cross section of the exhaust pipe is narrowed and the exhaust gas is blocked, resulting in engine fuel consumption. Increase, power drop, "overheating" phenomenon. Therefore, under normal circumstances, the exhaust pipe coke should be cleaned once every quarter to ensure the smooth exhaust of the diesel engine.
After the new machine is put into operation, the new machine is put into load operation to buy back a new machine. In addition to inspection and maintenance of the new machine, it must be run in strict accordance with the commissioning procedures specified in the instruction manual. The rotation speed is from low to high and the load is light to heavy. Eliminates the uneven machining marks on the friction surface of the part to make it smooth. Some operators bought back new farm machines and did not perform test run-in directly on the machines as required, resulting in a significant reduction in the service life of the machines.
Before and after the operation, many operators did not check that the inspection before and after the operation was not proper, which resulted in the loosening and detachment of parts and components of the agricultural machinery during operation and even harmed the human body. Therefore, before and after the operation of agricultural machinery, it is necessary to carefully stop the inspection of bolts, nuts, washers, and split pins in various parts. Loosening should be promptly tightened. Lost parts must be repaired in time. Wear-deformed parts should be repaired immediately to avoid minor losses. .
Accumulation of engine oil plus many machines. When the engine oil needs to be replaced, not all of them are replaced. Instead, new oil is added to the crankcase, so that the engine oil constantly “accumulatesâ€, mistakenly assuming that this not only ensures the lubrication needs of the diesel engine, but also saves expenses. . As everyone knows, oil after long-term use has deteriorated, impurities increased, lubrication quality decreased, at this time, even if the new oil is often added, it can not meet the oil quality requirements, resulting in accelerated wear of parts, greatly reducing the cylinder liner, piston and other machines The service life of the parts. At the same time, a large amount of impurities in the oil will adhere to the wall of the oil gallery. When it is severe, it will block the oil passage, which will result in the occurrence of failures such as shaft holding and burning of tiles.
