1:压力表水柱在低压时上升较快,随后逐渐减慢,到一定的度数后就不上

沼气池常见问题
    首先需要检查一下沼气池内的水位,如果水位太低,当沼气充满气箱,发酵液与进料口相平,沼气就会从进料口逸出。这时候,就需要增加发酵池内的原料和水分,升高池内水位,保持池内气压为零时,水位高于进出料口。还有一种可能的情况就是气箱或者输气系统有漏气的地方,造成气箱或输气系统跑气,而且漏气量与压力成正比,压力越高漏气越多。当压力低的时候,产气大于漏气,压力表水柱上升,当压力上升到一定的高度,产气与漏气相平衡,就不再上升了。所以,一旦出现这种情况,首先需要对方便检查的输气系统进行检查,检查输气管道、压力表等是否有小裂缝,如果有,要及时地修补或者更换。如果故障还未排除,就需要对气箱各部位进行全面的检查,首先应该按照故障表现7活动盖的检查和修补方法进行,如果活动盖不漏气,就是沼气池水压间池体有裂缝了。它的修理流程是这样的,先抽干沼气池内的沼液沼渣,用水冲洗干净,然后再把水抽干,把一只鸡放入池内,没有发现窒息死亡现象,就说明池内已经没有沼气了,维修人员就可以进入池内进行修补作业。修补的方法是发现裂缝时,用纯水泥浆在裂缝出涂抹,等泥浆干后,再涂抹,反复涂抹4遍以后就可以解决裂缝漏气了。
 PRESSURE GAUGE WATER COLUMN in the low pressure rise faster, and then gradually slow down to a certain degree after not onFirst need to check the water level in the biogas tank, if the water level is too low, when the biogas tank filled, fermentation liquid and feed port level, biogas will escape from the feed port. At this time, it is necessary to increase the raw materials and water in the fermentation tank, raise the water level in the tank, keep the air pressure in the tank is zero, the water level is higher than the inlet and outlet. It is also possible that there is a leak in the tank or gas transmission system, causing the tank or gas transmission system to lose gas, and the amount of leakage is proportional to the pressure, the higher the pressure, the more leakage. When the pressure is low, gas production is greater than leakage, pressure gauge water column rise, when the pressure rises to a certain height, gas production and leakage phase balance, no longer rise. So, once this happens, the first need to facilitate inspection of the gas transmission system to check whether there are small cracks in the gas pipeline, pressure gauge, etc. , if there is, to repair or replace in a timely manner. If the fault has not been eliminated, it is necessary to carry out a comprehensive inspection of the various parts of the gas tank, first of all, it should be carried out in accordance with the inspection and repair method of the fault performance 7 movable covers, if the movable covers do not leak air, it's the methane tank. There's a leak in the water pressure compartment. Its repair process is as follows: First, the biogas pond is drained of the biogas slurry, and then washed with water, then the water is drained, and a chicken is put into the pond. No suffocation is found, which means that there is no biogas in the pond Maintenance personnel can enter the pool to repair operations. The repair method is found cracks, with pure cement slurry in the cracks daub, such as mud dry, then Daub, repeated Daub 4 times after the crack can solve the leak.
2:用气时开关一打开,压力表指针上下波动
When the gas switch is turned on, the pressure gauge needle fluctuates up and down
   首先,检查一下输气管道,如果里面有积存的凝结水,只要放掉管道内的凝结水,并在输气管最低处安装积水瓶就可以了。如果输气管道里面没有凝结水,很可能是由输气管道、接头、开关等部位漏气引起的,对这些部位进行仔细地检查。如果输气管道漏气,需要从漏气处剪断,再用接头连接好;如果接头处漏气,需要拔出管子,在接头上涂上胶水,再将管道接头套紧就可以了;如果开关漏气,只要更换新开关就可以了。
First of all, check the gas pipeline, if there is accumulated condensate, as long as the discharge of condensate in the pipeline, and at the bottom of the gas pipeline installed a water bottle can be. If there is no condensate water in the gas pipeline, it is likely to be caused by gas leakage in the gas pipeline, joints, switches and other parts, and carefully check these parts. If the gas pipeline leaks, it is necessary to cut off the gas leak and connect it with a joint; if the joint leaks, it is necessary to pull out the pipe, apply glue on the joint and tighten the pipe joint; if the switch leaks, just need to replace the new switch.
3:正常产气的池子,在没有用气的情况下压力表指针下降,甚至为零
The normal gas pool, in the case of no gas pressure gauge pointer down, or even zero
 这很可能是由上次用气后,开关未关或没有关紧引起的,所以,出现这种情况,首先要检查一下开关是不是已经关紧了,如果开关没有关紧,用户需要把开关关紧,并注意每次使用沼气后,都要关好开关。
The normal gas pool, in the case of no gas pressure gauge pointer down, or even zero
This is probably caused by the switch not being closed or tightened after the last use of gas, so, in this case, first check whether the switch is already closed. If the switch is not tightened, the user needs to close the switch tightly And note that every use of biogas, must close the switch.
