Installation sequence of water pump in biogas desulfurization system:

1、起吊和运输时，起吊附件能保证吊件的支撑。提升泵电机底座应从泵和电机或底座的下部提升。提升单个泵应从泵进口法兰和支架上的吊环螺栓处提升。

1. During lifting and transportation, the lifting accessories can ensure the support of the lifting parts. The lifting pump motor base shall be lifted from the lower part of the pump and motor or base. Lifting individual pumps shall be lifted from the lifting eyebolts on the pump inlet flange and support.

2、短期储存/保管。当总成需要临时存放时，泵存放在干燥的地方，以免受到灰尘或腐蚀的影响。不应拆除泵入口和出口法兰上的保护盘。

2. Short term storage / safekeeping. When the assembly needs temporary storage, the pump shall be stored in a dry place to avoid the influence of dust or corrosion. The protective plates on the pump inlet and outlet flanges shall not be removed.

3、基础验收及处理，根据yl6809永利系统中水泵安装图对基础的尺寸和位置进行复检检查；混凝土基础具有足够的强度，以确保安*并按照相关标准进行安装。混凝清理，表面不得有油污或松散层。放置垫片的基础表面应平整。

3. Foundation acceptance and treatment: recheck the size and position of the foundation according to the installation drawing of the water pump in the biogas desulfurization system; The concrete foundation shall have sufficient strength to ensure safety * and be installed in accordance with relevant standards. After coagulation cleaning, the surface shall be free of oil stain or loose layer. The foundation surface on which the gasket is placed shall be flat.

4、整机就位、整平、灌浆，泵一般采用二次灌浆对基础预留洞进行整平。将地脚螺栓插入泵座的螺栓孔，装上垫圈，拧上螺母。对基础地脚螺栓预留孔进行灌浆，待混凝土凝固后拧紧地脚螺栓上的螺母，检查标高并校正，用无收缩水泥砂浆对泵底座进行二次灌浆，并用混凝土填充底座下方的空间，确保无气孔。焊接底座应浇注在槽钢底座的上表面。安装电机后，进行校正。

4. The whole machine is in place, leveled and grouted. The pump generally adopts secondary grouting to level the reserved hole of the foundation. Insert the anchor bolt into the bolt hole of the pump base, install the washer and screw the nut. Grout the reserved holes of foundation anchor bolts, tighten the nuts on the anchor bolts after the concrete is solidified, check the elevation and correct it, use non shrinkage cement mortar to conduct secondary grouting on the pump base, and fill the space under the base with concrete to ensure that there are no pores. The welded base shall be cast on the upper surface of the channel steel base. After installing the motor, correct it.
