Detailed description of the after-sales service of anyang iron and steel

I am the after-sales service of the after-sales service of the after-sales service department of the company after the after-sales service, wang yongfa, who received the after-sales instructions on November 27, 2016. The two pumps of anyang steel are leaking, so we can take a look at the site and deal with it. I arrived in anyang this afternoon and arrived at the scene early on the 28th. The field questions are as follows:

(a) ZZ160726 contract, if the factory site situation is: the scene with four HS200-150-385 - a, four pump head, a pump, of which 2 sets packing flushing water copper tube bending deformation is serious, field workers are removing the old pump on umc, clean up the old pump. I feel the scene is not too urgent; Then meet with install monitor, narrates the matters needing attention, we contact, tell people I'm in angang, what is up on the phone, I went to coking plant after lunch.

(2) at the site of the contract angang coking plant, there are 2 is50-32-250, 4 asp5040-50-200 hot water forced circulation pumps, 2 stage pumps. One of the is50-32-200 pump shell cracks, the water seepage when the pump stops, the water is worn at run time, and the replacement after simple welding is done first. Report the situation to the company that afternoon and coordinate the delivery and replacement with the owner.

(3) CQ160325 contract, chongqing sadi scene, the situation is: there are hs700-600-550c 4, hs400-350-400a 1, hs350-300-350b 1, zh50-30-1251, ih65-50-160 2, asp5030-40-315 1, ih65-50-160 2. At that time, sadie mainly reflected that the 4 hs700-600-550c pump current was too high to run normally. However, because there was no water in the circulation pool at the time, unable to pump the pump, unable to see the actual operation situation, we discussed with sadie and decided to add water to the circulating pool immediately, and then the test pump would be carried out after adding water.

Is when I first got to the scene above three general situation, the scene of the surface from November 30 until January 11, I crossed three site service, dealing with the three site users have found and put forward the problems and the situation and problems in the later. Below, I will present the three on-site service of this business trip. The situation, problems and handling methods of each site will be reported as follows:

(a) the situation and the problems that occurred in the site of a plant were mainly: (1) the repair of the heavy packing material was washed in the copper tube, which was done in a single morning. (2) find local local custom processing four pumps, three pumps of import and export flanges and purchase matching screws. This is because the three pump industry main buy only the pump head, did not indicate the mating flange and bolt in the contract, so our company didn't match were shipped, but the owner doesn't think so, and use the worry, do't zhengzhou deidara manager and sign the bill manager Su Cheng call to ask to buy in the local market, but the size and thickness of the flange on the market sell whatever one pump matching with our company are very different, can make to order, this to the market to find, flange, flange, buy form a complete set screw will take time. (3) the motor is installed and the coaxial scale is adjusted. Field has a pump together with the common base, motor is a piece of form a complete set of the past, we nearly two weeks late, but the motor and the motor pump of a complete set of supporting our past according to the owner and should be installed by our table, the key is found to pack machine, at that time, 315 kw motor base cannot put into our Shared base set blocks, I immediately to the company's after-sales department leadership has carried on the report, the scene to assist and supervise the workers work I also carried on the report to owner leadership, coordination, negotiation, decided to the scene to limit block for cutting, welding, change (with photo). It took three days for the owner to check out the same thing on a day. The four pumps are installed around December 15. (4) the four pump is used on the old production line upgrade, according to the arrangement of the whole production line transformation of construction schedule, try to pump is on December 27th, the first is packing packing fever can't open pump, reflect to the company, the company proposed replacing soft packing packing, the owner does not live, said before is a customized packing, according to the guidance of the company, I think after analysis using graphite packing is more appropriate, make the company send too slow, to go to the city to buy, packing to not fever, again because of the pump pressure is too high, and the three pump from the pump cover outside water jet pump body packing attaches to the things, can not only remove the pump cover repair pads to glue pressure. (5) bearing heating, the scene is a trial run, some pipe can't bear too high pressure, can only try a pump is a pump, and also three pump, a bearing fever, have a plenty of 20 minutes of running temperature of 76 degrees, and there's a turned more than 10 hours after more than 60 degrees, and rose to more than 70 degrees, the owner can't open, because the speed is too high, other manufacturers of pumps appear before burning bearing, and damage other parts, this time is December 31. According to the analysis and guidance of the company's technical department, the maximum temperature of 24 hours is not more than 60 degrees after handling each pump on January 3.

(2) the emergence of coking plant site, and the processing problems mainly include: (1) as I said, a IS50-32-250 pump shell crack leakage, after welding repair company new pump shell is 4 days after the arrival, was sadie scene is circulating water pump, report the situation and use to deal with during the solution, the analysis and research to the coking plant for the pump housing replacement, the coaxial degree, according to the owner to reflect and try to turn at the same time, the other a IS50-32-250 pump also have adjusted their alignment. (2) the owners reflect ASP5040-50-200 forced circulation pump hot water in cooling water pipe blockage, flow indicator does not turn, I have repaired their workers to the scene, but asked us in cooling water into the water head equipped with filters, through consultation and the suggestion, by the owner in total feed line equipped with filters. (3) at noon on January 9, sadie leaders signed ready to return to the office, but coking plant and reflect to the company, at the same time also had a phone call to me ASP5040-50-200 pump (with photo), have trachoma leaking pump body, to the scene, do have a below the outlet flange have trachoma in water at the same time. I immediately reported this situation to the company, and said that this is a high temperature and high pressure hot water forced circulation pump, and asked the company and technical department to give guidance and methods. On January 10, according to the company's guidance and site conditions, only 308A stainless steel electrode was used to break the welding. After repair welding is not missing, but the site owners worry that medium is high temperature and high pressure hot water, every time stop pump pump body temperature rise in a short period of time is fast, the weld cracking, is it possible to hurt people and then soup, asked whether company compensation.

(1) 4 hs700-600-550c pumps 8/560kw, the circulating pump current exceeds too much, and it can't operate normally. On the afternoon of December 5, when I was directing the installation of a factory, Mr. Sadie called to inform the supervisor of electrical appliances to test the pump on December 6th. At 9 p.m. on December 6 open pump, the valve closed condition 6.6-6.7 kg pressure, current 34 a, (nameplate head 25 meters, 5500 square, 560 kw motor, 40 a) rated current, the outlet valve open to 20%, the motor current has been to the rating, flow a little more than 2200. I reported the on-site situation to the company. After the research, the company decided to disintegrate the four pumps to remove the cover, and cut and balance each impeller. The model pump is 560 kw, pump cover only have 5 or 6 one hundred jins, rotor assembly more than one thousand pounds, a person won't do, can only live for someone to help, the scene construction group extort need $30000 overhaul fee to our company and also let the total package party to put pressure on our company. Let me find a factory to outside after the head of the company, cost leadership talk to each other by the company, the final cost is: the disassembling are all artificial, cutting impeller and dynamic balance, pulled back to angang freight each pump 4000 yuan, 4 pump a total of 16000 yuan. Cutting impeller units called anyang city stitt the science and technology co., LTD., the unit to remove processing facilities is really full, 200 tons of hydraulic rama, oxygen, acetylene, dynamic balancing machine, such as turning lathe. It took one day to disassemble four pumps and fixed each rotor with two machine seals for each rotor. Push the on site is urgent, and can run in angang factory is only a few did pass car, also have to make an appointment in advance, the somebody else at 5 PM after unloading the cargo come to pull the four rotor assembly directly into the processing, when the boss has to go off work, I also will go together with the cart after discharge. I asked somebody else to start after the company agreed to start pump, bearing, pull later 4 pump impeller dynamic balance amount after turning deviation is too large (more than 700 grams), before and after impeller cover nor very grinding, need to use drill holes at the inlet end, then turn back pack is installed in a test one, and the machine seal flush pipe bending loading up on site, flush pipe union seal leakage to buy replacement, driving fault delays, back pack, on December 24, pump vibration is big, to play table again. Since December 8 pump, completed on December 23, back pack, during the use of impeller machining gap and the factory day off, after the arrival of the goods, if the factory motor as mentioned again for someone to cooperate with our company altered the common base of form a complete set, the motor mount, playing table acceptance. Because of the severe haze pollution in the northern part of the country in late December 2016, anyang is no exception. The rest of the steel can stop completely, except that it can't be stopped. , 26 (2) 24 solstice sadie successively found and put forward before the situation and the problems to solve, 1 IH65-5.5 KW, 50-160 pump vibration noise, claw type coupling elastic hexagonal MATS have black powder fly out; 1 zh50-30-125 pump 2.2 KW, current super protector tripping; 1 asp5030-40-315, 30KW boiler feed water pump, set up machine seal leakage. First, after you remove IH65-50-160 motor found hexagon wheel play mat has become the triangle wheel, such a thing from the same company, time consuming and not save money, after reporting company outside bought a change up and reset the alignment, vibration noise elimination; ZH50-30-125 self-priming sewage pump is more trouble, the site electrical installation personnel, may be the motor internal wiring way is wrong, are generally small motor Y type connection, current is small, and he is the delta connection. Of course, this is only the analysis, and should also report to the company, contact the manufacturer. But after contact motor manufacturer said connection yes, estimation is pump choose big, or small protector, also let off pump test motor alone, but still jump protector, after off pump motor manufacturer also temporarily not to change or not, I finally agreed and electrical personnel, try to change to the first, I looked at the scene, if the motor protector not jump also not fever that in this way, if the motor is hot or have other abnormal it stopped immediately. Results after the fever, try turning protector jump motor and new problems, but the pump pump drive is not water, later found to be out of the water pipe is blocked, get out the pipe opened after 10 minutes without water, to give water pump housing don't work, I analysis it is possible to feed line need cutting feed line is too long the sadie engineer took the design drawings, say 3 meters deep pool 2, feed line 3 m won't plug, is on the pump suction force is not enough, also let me call the company, finally just pull down pressure pipe in my insistence, I use the rope to find out, do me a big bolt proof is indeed a feed line may be warp blocked, the family agreed to cut the feed line, cut short after the intake hose pump water, but the problem yet. The scene of the self-priming pump is used for sewage pump, that is to say he is not often or regularly, and the scene or automatic induction start-stop, so don't import and export valve (only one outlet check valve), electromagnetic inlet valve, pump itself also didn't bring this can make every last in the pipe of water pump is going to held the suction pump cavity back again, the next open pump have to add water, obviously the owner don't agree, finally negotiated owner to buy a guide field workers how to install. (3) the circulation pump of this contract is hs350-300-350b 75KW three, which reflects the large vibration and needs to be replayed. After the New Year's day after the New Year's day after the test pump, the maximum vibration 7 silk, basically can accept. (4) ASP5030-40-315 set mounted machine seal leakage problem, I obtained the consent of sadie, the disintegration of pump set mounted machine sealing apart, also found that the machine seal damage is not serious, and because the water has the machine caused by foreign bodies such as slag or Shi Touzi back deformation, machine seal leakage. Explain the situation to the client also gave the company the report, inform the company can repair, do not need to pay the compensation machine to seal. After the machine has been repaired and reloaded, no leakage can be used.

Company leadership, so I put all the things all busy, chongqing sadie leadership still don't agree with me leave, I need to present at the scene for some time, I didn't agree and also report to the company, the company is given clear instructions, the scene all problems have been processed, inform the customer after the withdrawal.
