渣浆泵机组安装顺序为

泵机组的安装顺序为:基础浇灌、底座安装、泵和原动机的安装。

一、 基础浇灌

泵的基础是用来固定泵和原动机的位置,承受泵和原动机的载荷,防止振动。对于大型泵的基础,要根据泵和原动机的动、静载荷进行正确的设计计算来确定,否则会造成垮塌、变形、振动。

固定使用的泵都应打混凝土基础,先挖好基坑,铺10 ~ 15cm的砂子或碎石夯实,如果土质过松,需要打桩加固,然后安放模板,扎钢筋,最后浇灌混凝土。基础般高出地面10-20cm,宽出底座10 ~ 15cm为宜。小型泵机组可采用砖或石块砌筑。

地脚螺栓固定的方法有两种,次浇灌法和二次浇灌法。

一次浇灌法是在混凝土浇灌前,先做好模框。将地脚螺栓固定定位在模框上,如图6-4所示。一次浇灌在混凝土中,拆下模框后,地脚螺检就固定在混凝上中。这种方法的优点是缩短了施工时间,地脚螺栓与混凝土的粘结较好,但螺栓的位置不易保证,灌混凝土时要小心,不要将地脚螺栓碰歪,一般只用于小型泵 (泵口径<300mm)的安装。

二次浇灌法是在基础上预留出地脚螺栓孔,般为100mm x 100mm的方孔(视地脚螺栓大小增减)。孔深为地脚螺栓长L+(100 ~ 200) mm待混凝土达到一定强度后,安装底座,上好地脚螺栓后再往预留的螺栓孔内浇灌混凝土,这种方法不会因地脚螺栓不正而造成底座安装困难。大型泵机组一般都采用二次浇灌法。渣浆泵厂家

The installation sequence of slurry pump unit is

The installation sequence of the pump unit is: Foundation pouring, base installation, pump and prime mover installation。

I。 foundation irrigation

The foundation of pump is used to fix the position of pump and prime mover, bear the load of pump and prime mover and prevent vibration. For the foundation of large pump, the correct design calculation should be carried out according to the dynamic and static loads of pump and prime mover, otherwise it will cause collapse, deformation and vibration.

Concrete foundation shall be built for all pumps in fixed use. The foundation pit shall be dug first, and 10 ~ 15cm sand or gravel shall be paved for compaction. If the soil is too loose, pile driving is required for reinforcement, then formwork shall be placed, reinforcement shall be made, and finally concrete shall be poured. The foundation is generally 10-20cm higher than the ground and 10-15cm wider than the base. Small pump units can be built with bricks or stones.

安徽快3开奖结果There are two methods to fix the anchor bolt, one-time pouring method and two-time pouring method.

The one-time pouring method is to make the formwork before the concrete pouring。 Fix and position the foundation bolt on the mold frame, as shown in Fig。 6-4。 One time pouring in the concrete, after removing the formwork frame, the anchor bolt inspection is fixed in the concrete。 The advantage of this method is that the construction time is shortened, and the anchor bolt and concrete are well bonded, but the position of the bolt is not easy to guarantee。 When pouring concrete, be careful not to touch the anchor bolt askew, which is generally only used for the installation of small pumps (pump diameter < 300 mm)。

The secondary pouring method is to reserve the anchor bolt holes on the foundation, generally 100mm x 100mm square holes (depending on the size of the anchor bolts)。 The depth of the hole is L + (100 ~ 200) mm of the length of the foundation bolt。 After the concrete reaches a certain strength, install the base。 After the foundation bolt is installed, pour concrete into the reserved bolt hole。 This method will not cause the base installation difficulty due to the incorrect foundation bolt。 Large pump units generally adopt the secondary pouring method。 Slurry pump manufacturer
