一、打开灶头开关后,压力表急剧下降,关上开关后压力表上升如果是输气管太长,在沼气池建池时最好把输气管路控制在25米以内,以保证沼气的正常输送。如果是输气管发生堵塞,应及时疏通输气管如果是脱硫器内的脱硫剂出现板结,阻止了沼气的输送,就要及时更换脱硫剂。二、压力表读数不持续上升用洗衣粉水或者肥皂水检查各管件接头 First, turn on the stove switch, the pressure gauge dropped sharply, the pressure gauge closed after the switch up If the gas pipe is too long, the best in the biogas digesters built in the gas pipeline control within 25 meters to ensure the normal biogas feed. If the gas pipe is clogged, the gas pipe should be dredged in time. If the desulfurization agent in the desulfurizer appears to have a plate knot and prevent the transportation of biogas, it is necessary to replace the desulfurizer in time. Second, the pressure gauge does not continue to increase readings with detergent or soapy water pipe fittings
