A water jacket pin device's design and production

A water jacket design 2020 - pull pin system 11 - 21 KouJianChang ( Utilizing the west hit the guest) One, the status quo of recently we repair fan-shaped segment in the process of carbon steel # 6 machine, user requirements we will fan section water cooling system for the overall maintenance, this needs us to check all the parts is remove water cooling system, we found in removing the water bearing supporting surface cooling water on the road there are four gland ( Hereinafter referred to as the water jacket) , due to the use fixed number of year is longer than the water jacket on the sealing ring damaged seriously need to change, but in the process of take out the water jacket is very difficult, because of the water jacket corroded seriously hard to pull out, first we take the method of welding nut on the water jacket, but because of the large size of water jacket, work efficiency is slow and after water jacket out basically all damaged ( Each fan-shaped segment has 112 water jacket) To reuse, enormous waste. Water bearing installed on the water jacket, improvement measures to improve the former to get off, all the 112 water jacket needs to be implemented a welder and a fitter 2 days to complete, and it also needs to be JiaGongShui set, so to restricted production schedule, in the process of take out the water jacket have workers pull pin system is put forward to twist into after welding nut to remove, inspired by the idea, we wonder if it is possible to design a special pull pin system to remove the water jacket, so we make use of the water jacket are installed on the seal ring groove design a special pull pin. Design and production of water jacket pin pull water jacket of pull pin 3, the effect of the new design of water jacket pin pull production comes out, we're just to remove a fan-shaped segment after the experiment, a fitter need only six hours can easily remove all 112 water jacket, and basically guarantee the water jacket is in good condition, the production efficiency improved significantly. Analysis of economic benefit: the place on put together is narrated, the use of this new type of water jacket pin, pull a fan-shaped segment repair can save artificial 26 hours, the water jacket to manufacture processing fee of 560 yuan, according to the artificial 40 yuan per hour, a fan-shaped segment can save direct costs 1600 yuan, a conservative estimate repair a year ten of the fan can save the cost of production in 1. More than 60000 yuan, and this kind of innovation concept is worth promoting.
