The steam generator is widely used in building concrete heating, tunnel steam curing, expressway steam curing, building steam curing Engineering and municipal steam curing engineering, Greening steam maintenance project, water conservancy steam maintenance project.

Bridge maintenance machine is also called steam generator. It is a steam curing equipment for precast bridges, T-beams and concrete components. It ensures that the newly poured concrete hardens in an appropriate temperature and humidity environment within a certain period of time. Effectively prevent the early dry crack of concrete and ensure the later strength and durability of concrete.

Steam curing of bridge cement concrete is the key technology to improve output and ensure quality. According to the conditions of materials, processes and equipment, the guiding ideology for establishing the maintenance system is to reduce the residual deformation and shorten the maintenance cycle as far as possible on the premise of ensuring the demoulding strength. Bridge Road maintainer is a kind of machine that forms high-pressure steam by heating and controlling water to continuously spray concrete pavement for road maintenance. Generally, when the concrete does not have sufficient strength, the premature evaporation of water will also produce large shrinkage deformation and dry shrinkage cracks, which will affect the integrity and durability of the concrete. The concrete curing steam generator plays a vital role in cement mixing, pouring, steam curing and other production links. The steam generator for bridge and road concrete curing can provide appropriate hardening temperature and humidity for concrete hardening, so that the quality of cement products can be strictly controlled. Jining Yinghua concrete curing steam generator has fast gas production speed, shortening steam curing time, accelerating the turnover of cement product modules and improving labor productivity, which is of far-reaching significance to the popularization and application of energy-saving maintenance of construction team.

Steam curing of beam concrete is divided into four stages: static stop, temperature rise, constant temperature and temperature drop. During static stop, the temperature in the shed shall not be lower than 5 ℃, and the static stop time is generally 3-6 hours to prevent cracks and porosity on the component surface, and then start heating up. The heating up temperature should not be too fast to avoid cracks due to excessive temperature difference between the component surface and the interior, The temperature rise rate shall not be greater than 10 ℃ / h, the constant temperature curing temperature in the constant temperature curing stage shall not be greater than 80 ℃ (ordinary portland cement), the relative humidity shall be maintained at 90% ~ 100%, the constant temperature curing time is generally 3 ~ 8h, the concrete temperature in the core of the beam shall not exceed 60 ℃, and the cooling rate shall not be greater than 10 ℃ / h. During steam curing and removal of thermal insulation facilities, the temperature difference between the beam concrete core and the surface, and between the surface and the environment shall not exceed 20 ℃. Steam curing shall be recorded every hour.

1、 Scope of application: (bridge, railway) concrete curing

1. Unique internal structure design without boiler use certificate

The water volume of this series of products is less than 30L, which is within the scope of exemption from boiler use certificate, that is, boiler use certificate is not required. The furnace liner is equipped with a built-in steam water separator, which solves the problem of steam with water and ensures the high quality of steam.

2. Adopt high-quality core component - electric heating tube

The electric heating pipe is not only made of high-quality thick wall 316L stainless steel pipe, with a service life of 30% longer than the commonly used 304 stainless steel pipe, but also adopts high-temperature magnesia powder and sealing material, with high temperature resistance up to 170 ℃. The service life of the electric heating tube is better ensured.

3. Adopt high-quality parts

All pipelines, instruments and meters are connected with stainless steel pipes or copper pipes. The electrical appliances are of domestic high-quality brands, safe and reliable use and luxurious configuration.

4. Multiple interlocking safety protection function

The product is equipped with overpressure protection such as safety valve and pressure controller verified by boiler inspection institute to prevent explosion accidents caused by excessive pressure of boiler; At the same time, it has limit low water level protection. When the water supply stops, the boiler will automatically stop working, so as to prevent the damage or even burnout of electric heating elements caused by dry burning of the boiler.
