Description

A kind of ductile iron pipe cement lining health automaton

Technical field

A kind of ductile iron pipe cement lining of the utility model health automaton belongs to ductile iron pipe cement lining health preserving equipment technical field.

Background technology

Ductile iron pipe manufacturing enterprise is in the ductile iron pipe production run, when the ductile iron pipe of producing after the hydraulic testing is qualified, cement coated lining process operations worker just carries out the operation of cement coated lining according to " ISO2531 " or according to " GB/T13295 " standard and manufacturing technique requirent to the pipe that flows into this procedure, the operation of cement coated lining is the sand-cement slurry of coating layer at the spheroidal-graphite cast iron pipe internal surface, this lining can improve its inside surface smooth finish, reduce the resistance to corrosion of resistance of water conveyance and enhancing product, after the operation of cement coated lining is finished, for guaranteeing after the coated lining that the concrete lining of pipe can dry up rapidly and dry, do not damaged by next procedure production, pipe that just must coated lining is good hangs in rapidly in the health pond, such pipe is carried out the liner health process; So be typically provided with cement coated lining and liner health operation at production line, for guaranteeing continuous production, a plurality of healths pond is all had to migrate for the production of week in each factory on its production line.

After the internal lining pipe that hangs in the health pond gathers some, cover immediately health pond lid, just can carry out the liner health and process; The internal lining pipe health divides two processes, and the first process is natural Health preservation, and natural Health preservation is not open that steam, health pond temperature must be higher than under 0 ℃ the state to carry out, and the internal lining pipe natural Health preservation time generally need reach more than 1 hour; The second process is steam curing, steam curing be after natural Health preservation is finished, give the internal lining pipe in health pond logical on steam carry out health; Steam curing carries out in two stages, namely open first little steam, health pond temperature be controlled under the state between 30～40 ℃ carry out health, carry out health until opening gradually large steam again after 2 hours until health pond temperature reaches to be incubated about 60 ℃, the steam curing time generally need reach more than 8 hours; When the internal lining pipe health, the water in the lining mortar needs slowly to evaporate to obtain good lining intensity.

At present in domestic each manufacturing enterprise, the logical steam curing temperature of internal lining pipe is to control by the quantity of steam that manual type is sent into adjustment, it is to be finished by the aperture of artificial unlatching steam valve that quantity of steam is regulated, its conditioned time also is to grasp by artificial and record of production, because manual randomness, the employee is to the difference of production Technology Grasping level and working sense of responsibility thereof, the impacts such as the factor of relieving appear in the continuous flow procedure, will certainly cause health temperature, the phenomenon that conditioned time does not reach the production technology code requirement occurs, in case this class phenomenon occurs, the health quality of internal lining pipe will go wrong, if its conditioned time is inadequate or health temperature is low, this class pipe goes out Chi Houhui and has lining maintenance is not good, sand-cement slurry is fully not dry, are damaged easily in lining two ends and surface, even can bring difficulty to later process production, also need do over again in case of necessity, also the lining cracking phenomena can occur through the certain hour section after this class pipe outbound; If its conditioned time is violated process specification requirements or health temperature control is too high, this class pipe goes out that lining cracking appears in Chi Houhui or there is the decortication phenomenon on the lining surface, it can increase the workload of later process, and directly affects the quality of internal lining pipe, and some pipe also must do to scrap processing; More than these phenomenons equal ubiquity in ductile iron pipe manufacturing enterprise.
