Abstract

The invention discloses a method for installing a switchgear in sewage treatment. The hoisting port enters at the gate of the power distribution room, and the height of the door cabinet should be such that the total height of the switchgear with a base wooden boat and a rolling load can pass through smoothly; the switchgear is Position transportation, using the combination of truck cranes, rollers, and chain hoists for hauling, build a wooden pile at the entrance of the power distribution room, place several rollers on the pile, remove the outer packaging of the switch cabinet, and keep the wooden boat at the bottom of the switch. Use gourds and manpower to haul to the side of the channel steel of the foundation, remove the wooden base and move it to the foundation and adjust it in place; the cabinet body is fixed by bolts and fixed by electric welding. Galvanized bolts are used for the connection between the cabinets; a uniform layer of electric compound grease is applied to the overlapping parts of the bus bars, and the connecting bolts are tightened with a torque wrench. The method enables the switchgear to be installed in place, shortens the installation time, and makes sewage treatment more efficient.

Description

technical field

[0001] The invention relates to a method, in particular to a method for installing switch cabinets in sewage treatment. Background technique

[0002] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage are pathogenic pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. From the viewpoint of the source of sewage, sewage can be defined as waste-carrying liquid or water discharged from residential, institutional, commercial or industrial areas mixed with groundwater, surface water, snowstorms, etc. There are many types of sewage, and correspondingly there are many technologies and processes to reduce the impact of sewage on the environment. According to the source of sewage, sewage can be divided into these four categories. The first category: Industrial wastewater Sewage from manufa...

Embodiment

[0013] A method for installing a switchgear in sewage treatment, comprising the following steps:

[0014] (1) The hoisting port is selected at the gate of the power distribution room, and the height of the door cabinet should be such that the total height of the switch cabinet with the base wooden boat and the rolling carrier can pass through smoothly. If the requirements cannot be met, a hole should be reserved when building the wall hole;

[0015] (2) The switchgear is transported in place, using a combination of truck cranes, rollers, and chain hoists for hauling. A wooden pile is built at the entrance of the power distribution room in advance, and several rollers are placed on the pile, and the outside of the switchgear is removed. Packing, keep the wooden boat at the bottom of the switch, use the crane to lift the 4 special hoisting rings on the top of the switch cabinet, hoist it to the pre-placed roller, use the hoist and manpower to haul it to the side of the foundatio...
