One, product overview: （ box sensor on a white plastic water box filled with water, do not need water ）

YH-40B / 60B /90B standard constant temperature and humidity curing box is based on national GB1345-99" cement standard consistency water condensation time stability test method" and the National Institute of building materials and the relevant departments to provide information technology design and manufacturing development, applicable to large, medium, small cement factory, building and construction sector, made of concrete cement test piece maintenance of condensation.

On the basis of the original products, a series of improvements, a box door with a magnetic tape sealing, insulation layer using better insulation effect of the thermal insulation cotton, internal added refrigeration unit, stable running, small noise, heater for brass and processing, anti-rust anti-corrosion, a humidifying device, handsome in appearance, controller of temperature and humidity control high precision a series of advantages, the use of additional user fault them out maintenance table, as the user during the maintenance to the factory provides a record of the basis, so I plant curing box in the production process can be improved, so that product to achieve durable meets the requirement of users.

In 9, the space in the box: type 40B can put 150concrete test block15 groups

60B can put 150concrete test block40 groups

90B can put 150concrete test block60 groups

Three, the structure and working principle:

1, structure

Box body is made of two layers, composed of an outer box and an inner box, an outer box body made of high quality cold-rolled steel plate, the inner box body adopts stainless steel plate, stainless steel material shelf, good corrosion resistance. The inner box body below the water tank for heating and humidification, humidification system for humidifying by ultrasonic instrument, water heating evaporation as a supplement, the automatic control system is composed of temperature controller and humidity control instrument according to a given temperature, humidity refrigeration, heating and humidification automatic switching, inside temperature, humidity by the digital display meter.

2, work principle

Temperature control: when the temperature is lower than the lower limit of temperature control instrument for the given value, temperature controller output heating signal command original electric began to work, and the temperature is higher than the maximum when the given value, temperature control instrument instruction work of the refrigeration system, when the temperature reaches the request, automatically stops heating or refrigeration.

The humidity control: using ultrasonic humidifier humidification, can guarantee the humidity inside reached more than 95%, the temperature controller can automatically control the humidification device, when the humidity is lower than 95%, temperature control instrument instruction humidifier work, achieve the return difference, stop working automatically, the return difference should be adjusted in 0-1C, not too big.

Four, the use of methods:

In 1, the box in place, adjust the level, grounded, rest for 24 hours, to the inside of the water tank with clean water, the water level exceeds the heating pipe.

2, open the door of the box, take out the humidifier. Opening side, the humidifier put on the tray, remove the transparent water tank, in turn, counter-clockwise rotation water tank cover, filled with clean water （ distilled water is best）, water is added after the screw on the tank cover, back into the humidifier humidifier nozzle according to maternal, then, finally the humidifier side inside the socket plug. Turn on the power switch, the spray knob is adjusted to a maximum position. Curing box temperature controller temperature, humidity of the factory has been adjusted.

3, the power supply is switched on, so that the instrument starts to work, the inside temperature humidity reaches a given value, and then into the specimen, heating and refrigeration is strictly at the same time.

In five, the main event:

1, curing box should be in ventilation, dry, smooth, no corrosion environment, daily use pay attention to keep the tank, humidifier water level, to ensure the normal use.

2, curing box in place, be still24 hours before the electricity starting, voltage should not be less than160V or higher than 240V, voltage instability will burn control instrument, must use the regulated power supply.

In 3, the compressor can't frequent start, refrigeration working power failure or stop must be an interval of 5 minutes, and then start two start, to avoid damage to the compressor.

4, equipment must not inverted, so as to avoid compressor lubricating oil and refrigerant mixtures, damaged refrigeration unit.

In 5, when handling shall be tilted 45 degrees.

In 6, working for insulation test, so as to avoid leakage risk.

7, to join the water in the water tank is preferably40 DEG c..

Six, common breakdown and elimination method:

In 1, the instrument display does not work

（1） power is not connected, check the fuse plug.

（2） the power switch to bad, to replace the new switch.

（3） the instrument output line off, plug plugging.

（4） the contactor burning, replacement of the same type contactor.

In 2, no refrigeration

（1） given the correct value of temperature controller, temperature controller does not output signal setting a given value or check the temperature fuse.

（2） temperature controller output signal contactor does not work, for contactor.

（3） refrigerant leak.

（4） the compressor does not work, the compressor through the power, if still does not work, that is the thermal relay or compressor burn out, must be replaced or compressor thermal relay.

In 3, the whole is not heated

（1） temperature control instrument and contactor burning need to replace.

（2） heating pipe dewatering burn, to replace the same power electric heating element.

In 4, the humidity in the box is lower than a given value without humidification

（1） to check whether a given value is correct, then the temperature controller of the switch to close, to see whether the spray, if not spray humidifier, description of fault.

（2） when the digital value is less than a given value, humidity control instrument lights are red, such as constant should be appropriate for the return difference of small, turn red without humidification humidifier should check.

（3） humidifier as not working properly, we should first check the transducer has no scale, impurity, the transducer must be kept clean, and whether the water tank.

（4） temperature controller can output signal should check instrument, temperature such as01-10% displayed is not abnormal, with a dry cloth to wipe the water mark sensor probe, which can normally display.

In 5, the magnetic tape is not tight heating method magnetic rubber strip widened （ with hair dryer ）

In 6, a chamber for water leakage of epoxy resin adhesive or welding of plastics.

Seven, humidifier maintenance

In 1, when not using a humidifier, please take off the power switch, pull the plug.

In 2, the following conditions must be cleaning humidifier:

1） appearance, smell.

2）, but not normal fog spray mist.

3）, mist or fog.

3, how to clean humidifier

1） when cleaning, take the humidifier capping, never put a humidifier soaked in water.

2）, do not use detergent, kerosene, alcohol or glass furniture chemical polishing agent, also cannot use more than 50DEG C hot water.

User troubleshooting self-test table

Fault exclusion

Thermostatic instrument rear temperature-sensing probe vibration off or electric heating tube.

LED light bulb is damaged or the power supply is connected with the imaginary, temperature fuse.

The differential sensitivity to start not to open the door of the box.

Water leakage chamber with epoxy resin adhesive.

Humidification Humidifier Replacement is not normal.

Do not put a water outlet valve plug

No refrigeration pipe blocking or in transportation pipeline leakage, to time, add fluorine

Not an electrical heating tube is damaged or connection mode off.

Lax door seal heating method the magnetic rubber strip widens, solution （ with hair dryer ）
