制冷压缩机机械加油一般分为两步:先用油泵将油桶内的油加入清油池,经沉淀除去杂质后,再加入制冷压缩机。将油桶内的油加入清油池时,首先遇到的是吸油管 A 的排空问题,若吸油管 A 内的空气排不净,就会在管内形成气塞,造成油泵吸油困难或根本吸不上油。在按装机械加油系统时,可在吸油管 A 和出油管之间加装一只 dg_(10)或 dg_(15)的直通阀(见附图),作为吸油管 A 的排空阀门。并在吸油管前段加接一段长的橡皮软管(软管前
Refrigeration compressor mechanical refueling is generally divided into two steps: first oil pump oil drums into the pool of oil, the precipitate to remove impurities, then add refrigeration compressor. When the oil in the barrel is added to the edible oil pool, the first problem encountered is the emptying problem of the suction pipe A. If the air in the suction pipe A is not completely discharged, a gas plug will be formed in the pipe, causing the oil pump to absorb oil or simply absorb Not oiled When the mechanical refueling system is installed, a dg_ (10) or dg_ (15) straight-through valve (see attached drawing) may be installed between the suction pipe A and the oil pipe to serve as an emptying valve for the suction pipe A. And in front of the suction pipe plus a long rubber hose (hose before
