Industrial autoclave is widely used in pipe pile, aerated concrete block, lime-sand brick, fly ash brick and other new building materials of high temperature and high pressure pipe, used to improve strength and excellent properties of the product.In the process of using, if the following problem, should take active measures to maintenance:
Corrosion of reaction caldron in the aeroconcrete production:
Corrosion on the harm of reaction caldron in the aeroconcrete production is quite big, not only can damage components, shorten service life of reaction caldron in the aeroconcrete, serious still can cause autoclaved kettle safety accidents.Common corrosion mainly aerobic corrosion and electrochemical corrosion, so you need to take the booster before sucking air in the kettle, the discharge of condensed water in time, regular cleaning tank bottom sediments and other measures to reduce the harm of corrosion.
Safety interlock reaction caldron in the aeroconcrete damage:
In the previous article, small make up for everybody introduced Zheng Guo autoclaved kettle safety interlock, safety interlocks of reaction caldron in the aeroconcrete production to avoid the operator can not decide whether or not the pressure in the kettle is zero wrong operation, greatly avoid the safety accidents.But when the safety interlock is damaged, cannot have the effect of protection, so in use after a period of time should check whether the device is work in a timely manner.
Above is of high efficiency and energy saving autoclaved kettle manufacturers Zheng Guo container, the analysis given in the next article, continue to introduce use of reaction caldron in the aeroconcrete production enterprise to problems arising from the use process, and found the problem, find ways to cope with the problem.
Kettle lid closed reaction caldron in the aeroconcrete production is easy:
If the perpendicularity of the kettle body flange is better, but by adjusting the kettle lid gearbox positioning screw nut, the kettle cover face about 5 mm lower than the upper outward tilt (as shown in figure 4).If the kettle body flange end verticality is larger, should readjust make it into the vertical or lower slightly tilted (no more than 2 mm).
Autoclaved kettle mechanical damage:
Products and maintenance vehicles in and out of the kettle in the process of wire rope or chain and other metal parts and kettle wall collision or scratch.Mechanical damage in addition to make the kettle body wall thickness thinning, and could accelerate the corrosion rate.As a result, those inside the kettle using wire rope or chain traction rope autoclaved kettle, should add spacing between track layout in the kettle hanging from the kettle bottom rollers, traction rope direct contact with the body to work.
Crack of reaction caldron in the aeroconcrete production:
Autoclaved kettle are found on the crack for the fatigue crack, the most common of which are still crack root department, with the structure of reaction caldron in the aeroconcrete production characteristics, and the running situation of carry alternating load, used as a unit is hard to avoid the cracks.Stress concentration of tank (e.g., nozzle), also can produce fatigue crack,
Autoclaved kettle foundation sink:
Autoclaved kettle used in foundation subsidence is one of the reasons for the improper design or construction, sinking position no rules to follow;Condensed water discharge is not timely, the bottom of the kettle and the kettle over 40 ℃, the temperature difference between the top body will start on the arch deformation (over 70 ℃ could kettle body material yield and damage), the result is based on both ends of the sink.
ZG’s production safety and reliability and longer service life, welcome to choose and buy.
