【Q&A Question 077】March 18, 2018: Briefly explain the reasons why an oil injector in a reciprocating compressor does not supply oil ① The oil filler is damaged. ② There is too little oil in the oil filler. ③Air is entering the oil filling tube. ④The oil level adjustment screw is not adjusted properly. ⑤The oil filter is clogged. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Due to the limitations on the number of posts in the “One Question per Day” section, “One Image per Day” has been moved to the registered devices section; you can access it through the directory I posted.

1. The lubricating oil added is not clean and contains impurities. 2. The oil injection pipe is blocked. 3. The opening of the regulator that controls the oil dripping rate is low. 4. Fault in the oil injector pressure boosting system; low oil injection pressure, preventing injection into the cylinder.

Answer: The situation where the oil injector does not supply oil is not common; the main reasons are: (1) wear of the plunger and an increased gap between the plunger and its sleeve. (2) The oil level in the oil filler is too low. (3) The filter screen inside the oil filter is clogged or the oil pipe is blocked. (4) Air leaks into the plunger sleeve or the cylinder exhaust returns to the oil injector. (5) The oil level adjustment screw is not adjusted properly.
Medium aspect: 1. Insufficient oil level, the oil surface is too low； Mechanical aspects: 1. Improper adjustment of the oil level regulator position ； 2. The seals are severely worn ； 3. Clogged filter mesh or oil pipe ； 4. Plunger wear
1. Plunger wear and increased clearance in the plunger sleeve. 2. Too low oil level in the injector. 3. Clogged filter screen inside the oil filter or blocked oil pipes. 4. Air entering the plunger sleeve or exhaust gas from the cylinder returning into the injector. 5. The oil level adjustment screw is not adjusted properly.
The oiler level is low, the oiler isn’t properly adjusted, and the low oil temperature makes the lubricant viscous
