China No.1 Heavy-duty φ 6260 mm EPB shield machine successfully passed the off-line inspection.

Qi Xin joined forces to grab the progress.

Unite with one heart to ensure production

On July 14th, the φ 6260mm EPB shield machine jointly produced by Tianjin Heavy Industry and China Railway Engineering Service Co., Ltd., after 32 days of hard work, successfully completed the whole machine assembly and electromechanical-hydraulic joint debugging, and passed the factory acceptance.

This EPB shield machine has a excavation diameter of 6.3 meters, a total equipment length of 75 meters, a total main driving power of 1,100 kilowatts, and a total thrust of 41,600 kilowatts. It has a horizontal turning capacity of 250 meters and will serve the urban rail transit construction in Hefei, Anhui Province.

Party member Commando was set up by Tianjin Heavy Industry, which organized elite soldiers to devote themselves to the intense equipment manufacturing task. They lead by example, take the initiative to undertake the hard work, and fight day and night in the production line.

When the final assembly and debugging of the shield machine entered a critical stage, there was no action in the forward and reverse rotation of the sudden screw machine. The commando team immediately organized personnel to carry out fault troubleshooting, worked out a plan overnight, and set the opening of the overflow valve after remote fault diagnosis, circuit troubleshooting, analysis of the working pressure moment of the screw machine on the operation panel, etc. The forward and reverse rotation of the screw machine was successfully resumed, and the final assembly of the whole machine and the electro-hydraulic joint debugging were completed ahead of schedule.

Canada’s increase in the quota for killing seals has once again caused global controversy (Figure)

  What awaits innocent baby seals may be the fate of being killed.


  


  The hunter clubbed the seal on the head.


  Canada’s commercial killing of seals has long been protested by many animal protection organizations around the world, but strong opposition can’t stop this cruel killing. The Canadian government even increased the quota for killing seals in 2008 to 275,000, an increase of 5,000 compared with last year, which triggered widespread criticism and protests around the world.


  The killing scene is extremely cruel.


  Every year from March to April, Canada conducts large-scale commercial hunting and killing of seals. These seals are either shot with guns or hit on the head with sticks, and the scene is extremely bloody. At the beginning of hunting, the hunters in the dinghy shot at once after seeing the seal on the ice. After killing the seal, the hunters peeled off the fur from the seal and threw it into the dinghy. Seal fur will be used to make leather clothes, and the bodies will be discarded.


  After the seals were shot, the hunters began to check their sex. If the female seal is killed, cut open and peel it on the spot, leaving the stripped flesh and blood in place; When they meet male seals, they drag their bodies to fishing boats, and then send them to processing plants for subdivision later. There are also some hunters who are extremely cruel. They snatch the baby seals directly from the mother’s arms, knock these young and helpless lives to death with sticks, and immediately peel off their fur. When the baby seals, who had just been born for two or three weeks and were starving, were lying in the sun on the smooth ice, the hunters’ sinful bullets had been continuously fired at their young bodies. Poor little guys have been skinned and boned before they can eat solid food, swim or even catch a cod to satisfy their hunger.


  Seals, a beautiful animal, are killed because they are all treasures, and their fur is used to make high-grade garments. In addition, their adipose tissue contains an unsaturated fatty acid called "omega 3", which is more than that of natural fish. People extract this substance and make it into precious nutritional supplements for sale in the market, and the demand is very huge.


  Animal protection organizations expressed strong protest.


  The cruel killing of seals, like whaling, has attracted protests from many animal protection organizations from the beginning. Many animal protectors think that the killing of seals is so cruel that there is no one to talk about. Sherry, a member of the International Animal Welfare Foundation? Sheryl Fink said that she was surprised that the Canadian government continued to increase the quota for hunting seals, and said that this behavior should not continue. She said: "This resolution to increase the quota for killing seals is unfair."


  As early as 2005, some environmentalists began to urge some American restaurants to boycott Canadian seafood unless the Canadian government stopped the commercial killing of seals. They said that the EU will soon introduce a ban on all seafood imports from Canada. Some animal protectionists say that the current Conservative government in Canada actually allows the killing of seals in order to win the support of the eastern region in the next federal election.


  However, despite the wave of protests, the Canadian government is indifferent. Phil Jenkins, a spokesman for the Fisheries and Oceans Department of Canada, recently denied that the population of Harp Seals in Greenland has decreased. He said, "At present, the number of Harp Seals in Greenland is good and sufficient, about 5.5 million. We hope to see these animals continue to grow healthily, so we have been keeping the number of seals killed within a reasonable range for many years. In addition, he also said: "We have a conservative method to keep the number of seals. We think that killing 275,000 seals is not enough to pose a threat to the number of seals." It is reported that the Canadian government has planned to set the date of killing seals in late March. (Dong Nan)
