SY-3 concrete pressure bleeding meter is made according to the international GB/T50080-2016 standard, which is mainly a special instrument for measuring the water secretion of pumped concrete under a certain pressure state, and then calculating the bleeding rate and pressure bleeding rate ratio. For the determination of pressure bleeding of concrete mixtures with aggregate size less than 40mm. The product also meets the requirements of JC473-92 standard.
Main technical parameters:
1. Model: SY-3
2, the maximum range of pressure gauge: 6MPa
3, the minimum separation value: not more than 0.1MPa
4, cylinder body diameter: 125±0.02mm
5, cylinder body height: 200±0.2mm
6, working piston diameter: 125mm
7. Working piston pressure: 3.2MPa
8, screen aperture: 0.315mm
9, net weight: ≈20kg
How to use:
1. Open the top cover, load the concrete mix that needs to be tested into the test barrel, insert the ramming rod from the periphery to the center 25 times, add the piston, and unscrew the vent screw of the piston, press the piston to the surface of the concrete, tighten the vent screw, cover the top cover tightening nut, and connect the quick joint of the manual pump and jack.
2, then clockwise tighten the manual spring back oil valve, pull the hand pump handle, the oil pressure to 30mpa(the value of the pressure gauge), then the pressure of the piston on the concrete mix is 3.0mpa.
3. When the oil pressure reaches 30Mpa, the bleeding valve is opened immediately, and the bleeding water is connected to the 1000ml measuring cylinder. At the same time, the timing is started, and the bleeding water V1 and V140 are read in 10 seconds and 140 seconds, respectively, as the basic data for calculating the bleeding rate.
4. After the data is obtained, loosen the oil return valve counterclockwise to make the system relieve pressure, remove the upper cover and the test barrel, place the test barrel on the stripper (random accessories), cover the upper cover, and tighten the two nuts. Tighten the oil return valve in the clockwise direction, pressurize the jack until the concrete and piston fall off automatically, remove the top cover and the test cylinder, loosen the oil return valve, and manually press back the jack piston. The test is over.
