【Q&A Question 244】September 7, 2018: Briefly describe the reasons for high exhaust temperature at the first stage and the corresponding solutions. Reasons: (1) Backflow of air through the suction valve at the second stage; (2) Blockage in the pipeline between the first and second stages; (3) Low volume and pressure of the incoming air, along with a high compression ratio. Solutions: (1) Replace the valve components; (2) Clean the pipelines; (3) Adjust the return flow at the first-stage inlet to increase the volume and pressure of the incoming air. . (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

1. High return air temperature 2. Poor heat dissipation 3. Weak cooling effect 4. High motor heating 5. High compression ratio 6. High condensing pressure 7. Refrigerant selection
The gas is compressed. External forces do work on the gas, causing its internal energy to increase; this increase in internal energy is manifested primarily as an increase in temperature.
Reasons: (1) Backflow in the secondary intake valve, (2) Blockage in the pipeline from the primary stage to the secondary stage, (3) Low inlet air volume and pressure along with a high compression ratio. Solutions: (1) Replace the valve components, (2) Clean the pipelines, (3) Adjust the return flow at the primary stage entrance...
(1) Backflow in the secondary suction valve; (2) Blockage in the pipeline from the primary stage to the secondary stage; (3) Low inlet air volume and pressure as well as a high compression ratio. Solutions: (1) Replace the valve components; (2) Clean the pipelines; (3) Adjust the return flow at the primary inlet to increase the inlet air volume and pressure.

Excessively high primary pressure ratio: Solution – Adjust the pressure ratio appropriately. 3. Faulty exhaust valve causing internal leakage: Solution – Switch to another compressor and repair the primary exhaust valve. 4. Excessive clearance volume: Solution – If there is a clearance adjustment system, control the clearance properly; if not, shut down the machine for repairs. 5. Poor cooling effect of the cylinder block’s cooling water: Solution – Increase the amount of cooling water used; if scaling is the cause, shut down the machine for maintenance
1. Backflow at the secondary intake valve; 2. Blockage in the pipeline from the primary stage to the secondary stage; 3. Low inlet air volume, low pressure, high compression ratio. Solutions: (1) Replace the valve components, (2) Clean the pipelines, (3) Adjust the return flow at the primary inlet...

The two-stage compression ratio results in greater workload, and there is a problem with the exhaust valve. High inhalation temperature
