Senior Manager of Cangzhou Test Instrument Co., Ltd. 15 100868755 is the first choice for the standard maintenance room.
A, concrete standard curing room equipment automatic constant temperature and humidity instrument main purposes:
It is suitable for standard maintenance of cement and concrete specimens in buildings, highways, scientific research and construction, and construction sites. It has the advantages of convenient operation, automatic temperature and humidity control and digital display. Professional concrete standard curing room designers can carefully design your curing room for you. Equipped with control equipment according to your room and needs.
Second, the working principle of the equipment
The equipment adopts the method of asynchronous control of temperature and humidity, that is, the electric heating tube is used for heating in winter, and the fan circulates, so as to achieve the purpose of indoor heating. In summer, the indoor evaporator is cooled by a compressor unit and circulated by an air cooler to achieve the purpose of indoor refrigeration. When heating, the pressure is increased to more than 0. 1MP by a water pump, and it is sprayed into a fog bead shape through a centrifugal nozzle, so that the standard culture room can be humidified.

Third, the standard room design and construction parameters
design philosophy
Standard curing equipment for concrete specimens: it is an instrument with high utilization rate in concrete laboratory and has been in uninterrupted working condition for many years. Therefore, the energy consumption is relatively large, and there are four ways to save energy, 1. The height of the standard maintenance room is about 2.4-2.7 meters, and the volume should not be too large. There should be a specimen rack to make full use of space. 2. Standard rooms cannot have windows. 3, circulating water to prevent leakage, one kilogram of water leakage of cold capacity is 10-20 kcal. 4. The refrigeration (heat) efficiency of the equipment should be high.
The air interlayer is designed, and the interlayer is filled with rigid paper foam plastic board, which not only has good thermal insulation performance, but also can prevent moisture from infiltrating from the inner wall to the outer wall and prevent the wall from freezing. In addition, the space between the two doors can be used to store mixed mortar specimens.
The temperature of standard curing room is often supersaturated, and the wall is saturated with water, which seriously reduces the thermal insulation performance. In order to overcome these mortar layers in the wall and the roof. The floor should be sprayed with epoxy resin paint three times (once a day), and the thinner (1: 2) is better for one time, which can effectively penetrate into mortar micropores. The second and third spraying of 1: 1 epoxy resin paint should be carried out after the equipment is installed, and the wall, floor and water pool should be repaired. Should be built. During construction, the nozzle should be wrapped to prevent blockage.
Note: During the above operations, no fire or sparks are allowed around to avoid acetone burning and explosion.
(2) Production of product pools
1. Location selection: The location of the water storage tank shall be as close as possible to the unit to reduce the pipeline length.
2. There are drainage holes at the bottom of the water storage pool, and the pool mouth should be covered with the steps of the cover plate. After the cover plate is covered, the plate surface is flush with the ground. The cover plate is made of wood, but it needs anti-corrosion treatment.
3. The stagnant pool is a high point on the ground of the standard maintenance room. In order to prevent sewage from entering the pool, the backwater ditch is inversely proportional to the stagnant pool. (that is, the backwater ditch of the ponding pool can make water flow into the ponding pool)
(3) Fabrication of ditches
There should be a floor drain at the ditch, and the ditch depth is gt; 5cm, the bottom extends horizontally to the pool, the water flows through the slag pit, and the mud can sink into it, which can reduce the nozzle blockage.
(4) Making holes in the wall
Selection of wall hole position: according to the prototype hole.
(5) Units with heating should try to install heating and valves indoors, which can save electricity. The heating flow is regulated by the valve. When the equipment is not started, the room temperature shall not exceed 65438 08℃, and the phenomenon of "cold and warm" lights shall be avoided as far as possible in winter.
Fourth, the installation of equipment.
(1) Installation sequence
The general installation sequence is: unit, pipeline and insulation layer, nozzle and power switch.
(2) Be as close as possible to the pool in the standard room, with at least 40cm space around the unit for easy maintenance.
(2) The machine room shall be well ventilated, and the hot air discharged by the unit shall be blown out of the window or wall hole through pipes or exhaust fans. When the unit is running, windows should be opened in the machine room to form convection.
(2) Circuit installation
1. controller: at the top of the unit, unplug the power cord and two cables of the sensor and connect the leakage protector.
2. A 30-amp power switch, as shown in the attached figure, to which the power cord is connected. Be careful not to connect the zero line wrong, but connect it firmly, otherwise it will burn out the components.
3. Lighting cable: through the hole in the wall, waterproof lights are required on the sprinkler.
4. Sensor cable: After passing through the wall hole and entering the standard maintenance, it can be hung along the steel pipe string and the sensor bracket, and the height is about from the nozzle to the ground center.
5. Ground wire of the unit: it should be firmly connected with the special ground wire. If there is no special grounding wire in the temporary house, the grounding wire with steel plate should be buried under the ponding pool.
6. The above wires and cables are fixed on the wall with cement steel nails, and their directions should be horizontal or vertical and uniform.
