The vacuum freeze dryer has become the leader in the drying field because of its obvious advantages. The advantage of vacuum freeze-drying is that it can reduce the probability of oxidative mildew of raw materials, solve the bacteria in raw materials, ensure the quality, and the original design of raw materials can be very well preserved.
Today, I will tell you how to solve the problem that the vacuum degree of the vacuum freeze dryer cannot be reduced:
Cause:
1. The temperature of the pump is too high. It is likely that the pump casing or inner wall of the vacuum freeze dryer pump is worn and the motor rotor pivot is offset, causing damage on both sides.
2. Oil valve: 1. The oil volume is too low, and the sealing is not tight; 2. The oil is yellowish brown due to environmental pollution; 3. The oil volume is normal, the fuel pipe is blocked, and there is no moderate remaining oil in the pump cavity.
3. The air inlet filter is blocked.
Clear way:
1. Reassemble after repairing.
2. Supply oil; change the oil; check the remaining oil in the fuel pipe and the fuel pump.
3. Details of common equipment failures, replace the sealing ring or pump casing.
4. Remove and clean.
Therefore, in addition to the correct use of the vacuum freeze dryer, we must also master the usual maintenance and maintenance of some machinery and equipment.
