Freeze dryers provided by freeze dryer manufacturers
Freeze Dryer Vacuum System Failures Provided by Freeze Dryer Manufacturers
1. The freeze dryer vacuum system provided by the freeze dryer manufacturer has a low degree of vacuum. Cause: Pump temperature is too high, it may be the pump blade or inner cavity scratches and wear, the displacement of the rotor shaft caused by single-sided wear. There is a problem with the pump oil: the oil level is too low and the seal is not tight; the oil is contaminated in yellow; the oil level is normal, the oil path is not open, and the pump chamber does not maintain a proper amount of oil. Leakage of the pump itself: The sealing ring, gas needle valve gasket is damaged or not pressed, the exhaust valve piece is damaged, resulting in a bad seal. Air inlet filter is blocked. Remedy: Reassemble after repair. Refueling; oil change; check the oil level of the oil and oil valve. Replace the sealing ring or valve disc for specific conditions. Remove the cleaning.
2. The freeze dryer vacuum system motor provided by the freeze dryer manufacturer is overloaded, abnormal noise, noise, and rotation are difficult during pump operation. Cause: Pump temperature is too high, it may be the pump blade or inner cavity scratches and wear, the displacement of the rotor shaft caused by single-sided wear. The spring is deformed or broken, causing the rotary blade to receive a shock due to the uneven force. The filter is damaged and the debris falls into the pump. The pump cavity is heavily contaminated and parts are rusted. The pump chamber shaft and bushing are too tight, resulting in poor lubrication. Remedy: Reassemble after repair, replace the spring, remove the wash, change the oil, reassemble, and unclog the oil circuit.
3. The freeze dryer vacuum system provided by the freeze dryer manufacturer leaks oil and injects oil. Cause: The seal ring of the shaft, oil window, oil drain hole, etc. is damaged or improperly assembled. Air inlet pressure is too high. Excessive oil produces fuel injection. The oil deflector under the exhaust cover is installed in reverse, causing oil injection. Remedy: Replace the sealing ring or reassemble, try to reduce the amount of oil, release part of the oil, and reassemble.
The advantages of freeze dryers from freeze dryer manufacturer:
1. Many heat-sensitive substances do not denature or deactivate;
2. When the material is dried at a low temperature, the loss of some volatile components in the material is very small;
3. In the process of lyophilization, the growth of microorganisms and the action of enzymes cannot be performed, so the original traits can be maintained;
4. Since the drying is performed in a frozen state, the volume is almost constant, the original structure is maintained, and no condensation occurs;
5. Since the moisture in the material exists in the form of ice crystals after pre-freeze, the dissolved inorganic salt dissolved in water is uniformly distributed in the material;
6. The dried material is porous and porous. It dissolves quickly and completely after adding water, and it almost immediately restores its original character.
7. Since the drying is carried out under vacuum, oxygen is minimal, so some easily oxidized substances are protected.
