Use and maintenance of cement Ray's boiling box
. Preparation of test cake method and Ray's method specimens:
Test cake forming: take out a part of the prepared slurry and divide it into two equal parts , make it into a spherical shape, place it on the prepared glass plate (), gently vibrate the glass plate and wipe it with a knife wiped with a damp cloth from the edge to the middle, making it into a diameter of ~, a thickness of about 100 in the center, a gradually thinning edge, and a surface Put the smooth test cake into the curing box and cure it until.
Preparation method of Leigh's clamp specimen: Place the pre-prepared Leigh's clamp on an oiled glass plate (mass about ~) and immediately fill the test mold with the prepared standard consistency paste , when installing the mold, gently hold the test mold with one hand, use the other hand to insert a wide knife about once, then smooth it, cover it with a slightly oiled glass plate, and then immediately move the test mold to the curing box. Maintain to.
.According to the user's requirements, the cake test method and the Ray's method are used simultaneously to compare the cement stability test results. The height of the grate plate is specially reduced. For this reason, the user is requested to be sure when using the grate plate (including only doing the Ray's clamp method) Place on a pie tester.
. Fill the boiling box with water (from the bottom of the inner box). Remove the cured test cake or Ray's clamp from the glass plate and place it flat on the cake test rack or Ray's clamp with the two pointers facing up. Place the mold horizontally on the grate board.
.Connect the power supply to the electrical control box and activate the automatic switch. The water in the boiling box will boil after about a minute. A group of electric heaters will automatically stop working and the indicator light will go out. Then the other set of electric heaters in the boiling box automatically stops working and the indicator light goes out. At this time, the digital display is, and the buzzer in the electrical control box sounds, indicating that the work is completed. After boiling, release the water from the electric hot water nozzle, open the lid of the box, wait for the box to cool to room temperature, and take out the test piece for testing.
.If the temperature of the water in the boiling box is lower than ℃, you can first place the manual and automatic switch on the electrical control box in the manual position and the heating and thermostat switch in the heating position. Heat the water to about ℃, and switch the manual and automatic switches to the automatic position to run automatically.
. Clean fresh water must be used in the boiling box. After the equipment is used for a long time, scale may accumulate in the box. The user can clean it regularly as appropriate.
.The power supply voltage of this equipment is AC, and the two sets of heaters are both sum and water. Before heating, water must be added to the height to prevent the heater from overheating and burning out. After heating is completed, first cut off the power supply, and then drain the water in the tank. In order to ensure the efficiency of the heater, the surface of the heater should be frequently scrubbed to remove scale.
The box shell must be reliably grounded to ensure safety.
.Before boiling, the water sealing tank must be filled with water to ensure the water sealing effect during test boiling.
When moving this equipment, be sure not to exert force on the water seal tank cabinet (serial number in Figure 1).
.The aviation socket used to connect the electrical control box and the boiling box must be correctly identified. The wiring number is the heater, the neutral line is the number, and the heater is the number. Each is (and)
Electrical schematic diagram of cement Ray's boiling box
Overview of cement Ray's boiling box:
Department of industry standards "Cement standard consistency water consumption, setting time, safety inspection "Method" stipulates that the supporting equipment used can automatically control the time for the water in the box to heat up to boiling and maintain boiling to test the stability of the cement slurry volume (i.e. Ray's method and cake test method). It is an important tool for cement production, construction and scientific research. , one of the special equipment for teaching units.
Operating procedures:
According to user requirements, the cake test method and Ray's method are used simultaneously to compare the cement stability test results. The height of the grate plate is specially reduced. For this purpose, the user is requested to use the grate plate (including only (Doing the Ray's Clamp Method) Be sure to place it on a cake testing rack.
. Fill the boiling box with water (from the bottom of the inner box). Remove the cured test cake or Ray's clamp from the glass plate and place it flat on the cake test rack or Ray's clamp with the two pointers facing up. Place the mold horizontally on the grate board.
.Connect the power supply to the electrical control box and activate the automatic switch. The water in the boiling box will boil after about a minute. A group of electric heaters will automatically stop working and the indicator light will go out. Then the other set of electric heaters in the boiling box automatically stops working and the indicator light goes out. At this time, the digital display is, and the buzzer in the electrical control box sounds, indicating that the work is completed. After boiling, release the water from the electric hot water nozzle, open the lid of the box, wait for the box to cool to room temperature, and take out the test piece for testing.
.If the temperature of the water in the boiling box is lower than ℃, you can first place the manual and automatic switch on the electrical control box in the manual position and the heating and thermostat switch in the heating position. Heat the water to about ℃, and switch the manual and automatic switches to the automatic position to run automatically.
. Clean fresh water must be used in the boiling box. After the equipment is used for a long time, scale may accumulate in the box. The user can clean it regularly as appropriate.
