Description
Technical field
The utility model is related to a kind of small dimension pipeline internal washing nozzle, particularly cleans diameter in 18~mm25 format diameters copper pipe or other texture pipeline nozzles, especially cleans condenser plug nozzle.
Background technology
At present, the equipment in steam power plant's air blast workshop is generally condensing-type stem-driven turboblower and condensing steam turbine generator.All carry out that the time do not wait to stem-driven turboblower and steam turbine generator every year it is big or middle repair or rush to repair work, blown with ensureing that stem-driven turboblower is safe and stable, be efficiently blast furnace.Wherein, it is exactly mud in cleaning turbine steam condenser copper tube, dirt to have a highly important job in maintenance steam turbine, to ensure that condenser has optimal cooling effect.According to the of different sizes of unit, the quantity of each unit condenser copper pipe is from 4000 to 6000,6 meters of copper pipe length, diameter 20mm or so.The method specifically cleaned is：When steam turbine is stopped transport, after condenser end cap is pulled down, an end of soft ribbons is connected on jetting machine, it is another to terminate to drill rod afterbody.After jetting machine, which is operated, to pressurize, six delivery ports on drill rod head can spray water under high pressure, then by drill rod manually was disclosed into condenser copper tube by root, now water under high pressure can rush the mud inside copper pipe and on tube wall, dirt to condensing engine rear portion, be discharged through bottom blow-down door.In cleaning process, because the delivery port diameter of six hole nozzles only has 0.6mm, easily sounding blocks water outlet lip reflex, causes nozzle delivery port water under high pressure to interrupt.
Forming the reason for nozzle delivery port is blocked has：1st, the bits produced after drill rod internal rust block delivery port, and it is that this reason is caused to have 70% blocking water jet outlet.After maintenance terminates drill rod storage, increase over time, the water inside drill rod makes drill rod inner pipe wall get rusty, and gradually forms bits.During drill rod use, bits are poured six hole nozzle heads behind drill rod inside and block delivery port by High-Pressure Water.2nd, there is silt blocking delivery port in cleaning water, and it is that this reason is caused to have 30% blocking water jet outlet.It is that sand grain is carried in Huanghe water, water due to cleaning condenser copper tube with water.After sand grain constantly assembles nozzle head formation certain amount, it may occur that block water outlet lip reflex.
Because the connected mode of six hole nozzles and drill rod is gas weld joint, the method for six hole nozzle delivery ports blocking was solved in the past is：The drill rod of plug nozzle delivery port is changed, more renews drill rod, upper six new hole nozzles are welded after six hole nozzles of blocking delivery port drill rod are cut, the drill rod that six hole nozzles are welded again is standby.
There is following defect in the method：1st, waste of material is caused.20, the existing drill rod in workshop, checks that just having the about 70% hole nozzle delivery port of drill rod six to block during drill rod needs to change before cleaning.The drill rod of nozzle delivery port blocking is also had in cleaning process to be needed to change, minimum nozzle delivery port of once changing blocks 5, drill rod in actual cleaning process, and the hole nozzle of blocking six cut down will be scrapped and can not reuse, by maintenance in 1 year, clean 7 turbine condensers calculating, there to be six hole nozzle about more than 140 to scrap, and cause waste of material.2nd, drill rod influence repair schedule is frequently changed.Because stem-driven turboblower is the essential motivational guarantee of blast fumance, therefore overhaul of steam turbine is repairing mostly.To ensure repair time and effect, factory can all formulate tight network inspection time diagram, and the accurate repair time is formulated to steam turbine and each portion's maintenance of blower fan.And change the drill rod time that six hole nozzle block → cut off the water → from termination of pumping unload the drill rod of plug nozzle delivery port → more renew drill rod → water flowing → pump → normal work, take around 20 minutes or so.Calculated by 5 drill rods of the minimum replacing once of actual cleaning works, the time for changing drill rod is 1.5 hours, this significantly impacts the progress for cleaning condenser copper tube, causing the repair time increases, so as to have influence on the whole network inspection time, making stem-driven turboblower, normally the time of blowing postpones, and influences blast fumance.
Nozzle is set to be threadedly coupled with drill rod formation.After six hole nozzle delivery ports are blocked, stop jetting machine → cutting off the water → and unload plug nozzle → more renewing nozzle → water flowing → and play a jetting machine normally to clean, this process takes around 10 minutes, although the method can shorten the time for changing plug nozzle delivery port drill rod, but in cleaning process, because six hole nozzle tailing screw flight tube walls are very thin, condenser copper tube diameter is smaller, can occur nozzle afterbody breakage phenomenon, six hole nozzle afterbodys more renew nozzle after fractureing can increase replacing construction on the contrary, and make into after the formation of six hole nozzles and drill rod is threadedly coupled, the hole nozzle of blocking six changed will also be scrapped, the waste of material mentioned among defect one is not solved the problems, such as.3rd, workman's workload increase.The hole nozzle delivery port of drill rod six that 70% is there are about before maintenance is blocked, and plug nozzle is welded the drill rod for also being had in new nozzle, cleaning process and blocking six hole nozzles again by workman after need to cutting, new nozzle need to be welded again with standby, workload of the workman in maintenance is increased.
