According to different ambient temperatures use of different grades of diesel (to see Table 1); the content of low-grade fuel oil in paraffin and sulfur; diesel fuel is not contaminated with impurities, dust and water, used excavators prices will keep the fuel pump premature wear high, used excavators price lists, the engine will cause harm; daily job to fill the fuel tank after the fuel tank to prevent the inner wall of water drops; daily work before opening the fuel discharge bottom drain valve; in the engine ran out of fuel or After replacing the filter, even though the road to be ranked in the air. Cause minimum ambient temperature 0 ℃ -10 ℃ -20 ℃ -30 ℃ grades of diesel 0 # -10 # -20 # -35 # cracks excavator boom side cracks reasons: including the original weld itself bubble, slag and small cracking when overworked excavator, used excavators price chart, the original weld will produce tiny cracks and slowly expand: the welding electrode and the plate does not match the performance and cracks: Due excavator arm bulky, difficult to use, reliable and effective heat insulation measures, has not been completely removed after welding seam surrounding base metal hardened area, resulting in weld strength decline: Excavators greater impact vibration during operation, weld force uneven weld cracking. Used excavator price, Jin Hao used excavators, used excavators price list provided by the Shanghai Used Construction Machinery Co., Ltd. Jin Hao. Used excavator price, Jin Hao used excavators, used excavators price list is Shanghai Jin Hao Used Construction Machinery Co.
