The filter cloth is clogged ； 3. The liquid level in the alkali tank is too high ； 4. The firing rate of the extracted liquid is too low. 5. Full liquid level in the integrated recovery tower and separator
1. The vacuum pump does not receive water supply or the supply is insufficient. 2. There is a leak at the packing of the pump. 3. The temperature of the water ring is high
The vacuum pump does not have sufficient water supply or the supply is inadequate; there is a leak at the pump’s packing area, and the temperature of the water ring is high
The vacuum pump does not have sufficient water supply or the supply is inadequate; there is a leak at the pump’s packing area, and the temperature of the water ring is high
The reasons are as follows: 1. Vacuum pump failure； 2. The filter cloth is clogged ； 3. The liquid level in the alkali tank is too high ； 4. Full liquid level in the integrated recovery tower and separator; 5. Scaling and blockage in the vacuum pipes
The reasons include a faulty vacuum pump, corroded impellers, clogged filter cloth in the filter, and high liquid level in the separator
Briefly explain the reasons why a vacuum pump does not draw in air or has insufficient pumping capacity Answer: ① The vacuum pump does not receive water supply or the supply is insufficient; ② There is a leak at the pump’s packing; ③ The temperature of the water ring is high.
