Cottle Compressor Troubleshooting Symptom one: big or compressed fuel oil unit volume. Too much oil, the correct position when the unit is loaded observation, this time, the oil level should be no higher than half. Put the oil return pipe to the proper position a blockage approach: clean up the blockage two return line installation (at the bottom of the oil in the oil separator core distance) does not meet the requirements, processing methods: replacement of the suction pipe. Unit 3 is running low exhaust pressure approach: increase the exhaust pressure 4 oil core quality approach: the replacement of the oil core five core rupture oil processing: Replace oil core six separate internal partitions damaged Simplified approach: replace 7 cylinder unit has leakage treatment: 8 oil deterioration or extended maintenance use treatment methods: 9 exhaust temperature is too low to replace oil processing methods: improving the exhaust temperature to about 85 ℃ Symptom 2: 1 actual low pressure unit gas consumption is greater than the unit output volume. Treatment: Re Selection 2 vent valve failure (can not turn off-loaded) approach: the vent valve repair or replacement of three intake valve failure can not be fully open approach: Qin Wei intake valve repair compressor cleaning, lubrication or replacement tube 4 users network has leaked approach: Maintenance 5 minimum pressure valve stuck approach: the need to re-adjust to clean or replace the air filter clogged body 6 new approach: replace the air filter condition condition characterized by mobile air compressor portable air compressor characterized by: (1) mobile air compressor to be able to facilitate the move often, changing working conditions, load changes; (2) mobile air compressor mostly heavy-duty, medium-speed or low-speed driving, most require frequent starts empty press, and often withstand shock loads; bad (3) wild, wet with rock dust, coal dust and gas (mostly methane) air compressor price, there are some harmful gases containing sulfur (sulfur dioxide, vulcanized hydrogen) air compressor repair, so many mobile air compressor must meet fire, explosion, corrosion problems; (4) open mobile air compressor to be able to withstand wind, sun, rain and hot summer and winter Cold climate change; (5) Due to limited space, the machine's maintenance more difficult, thus requiring mobile air compressor to be durable and easy to repair.
