"Hercules" on the site of safety valve maintenance

“Be sure to look at stability, and be careful!” In Shengli Oilfield, the CHP wins the inspection of the Nantongfeng Heats team. Maintenance personnel are working together to lift the motor with a chain and place it on the pump platform.

Maintenance work is both a skill and a work. Delicate minds are the advantages of female workers, and the handling and installation of heavy safety valves, manholes, etc., is the male workers are most good at, in particular, decontamination devices, motors, large valves, etc., really can not do without these "Hercules" . When the pump is disassembled, these maintenance personnel first pull out the impeller with a puller, remove the impeller from the pump shaft with a crowbar, and then lift the motor with a reciprocating chain and set it aside.

Crowbars, cranes, inverted chains, brackets, etc. are the best tools for maintenance personnel. Because the equipment needed to be overhauled was too heavy or had to be moved for a long time during installation, it was not humanly possible. They took a variety of methods.

This is not the case. At the site of the decontamination and decontamination of the Xinghe Thermal Power Plant, the filter weighed four or five hundred pounds. When the two or three people were removed, they could be moved aside. However, after the inspection is finished, it is difficult to install it. No one can achieve it. Then, they borrowed a crane, suspended the filter with a nylon strap, placed it on the cleaner, and continued to hang the shaft in the middle until it was fully adjusted. Ma Yongguo, Party branch secretary, said: "You must lift the axis for a long time, and even if the male workers can not move, they can use the crane easily."

Carrying a safety valve is also an effort. The safety valve is about thirty or forty pounds light. It can be removed from the top of the boiler and taken directly to the ladder. Heavy at least 130 pounds or so, manual handling is both laborious and unsafe. The Shenghua Heating Team ties the wire rope to the water outlet pipe, fixes the pulley, and then passes the rough hemp rope through the pulley, and ends with a safety valve and a worker. Pulling it, the heavy safety valve was "airlifted" and then moved by a relatively large force.

Each team combines the characteristics of the overhaul work, according to the heavy work and light, male workers and female workers, etc., carried out a reasonable division of labor. Ju Lixia’s female worker, Wang Lixia, said: “Different labor divisions between men and women, our team’s energy is generally deputy captain Cui Chun with a few strong laborers to do the work, clean heat exchange film, external network insulation brush painting and other work, our female employees When you don't let it."

The large valves of DN250 and DN300 on the pipeline weighed seventy-eight jins. It was dizzy to watch. To get rid of it and move it in, even the “strong manpower” was difficult. Therefore, when the dismantling is overhauled, the Juhua Heat Team is generally disassembled and the upper valve body is removed for maintenance. When the valve is damaged, the entire valve has to be replaced and transported. Cui Chun introduced: "We generally use coarse hemp rope to tie the valve and then use a crane to lift it up. This is also true for installation."

Hercules, clever methods, and auxiliary tools made them overcome the difficulties of one after another overhaul and eventually completed the first phase of maintenance and repair tasks.
