                                              SY-2 concrete pressure bleeding instrument quality product parameters picture manufacturer - Hangzhou Sansi 砼 pressure bleeding meter
                                               
                                              The SY-2 concrete pressure water meter produced by Hangzhou Sansi Instrument Co., Ltd. is made according to the international GB/T50080-2002 standard. It is mainly used to measure the amount of bleeding of pumped concrete under certain pressure conditions, and then calculate the bleeding rate and pressure bleeding rate. Specialized instrument. It is used for pressure bleeding test of concrete mixture with aggregate particle size not more than 40mm. The measurement value is accurate, the operation is simple, the volume is small, the weight is light, the demoulding is convenient, and the technical indexes thereof conform to the national JC473-92 standard. The instrument is mainly composed of a hydraulic jack, a pressure gauge and an upper cover piston, a test cylinder, a base and the like.
                                              First, the main technical parameters of SY-2 concrete pressure bleeding instrument
                                              1, model: SY-2
                                              2, the maximum range of pressure gauge: 6MPa
                                              3, the minimum division of the value: not much greater than 0.1 MPa
                                              4. Inner diameter of cylinder: 125±0.02mm
                                              5, cylinder height: 230 ± 0.2mm
                                              6, working piston diameter: 125mm
                                              7, working piston pressure: 3.2MPa
                                              8. Screen aperture: 0.315mm
                                              9, net weight: ≈ 20kg
                                              Second, the use of SY-2 concrete pressure water meter
                                              1. Open the upper cover, put the bismuth mixture to be tested into the test cylinder, insert the cymbal from the periphery to the center 25 times, add the piston, and unscrew the vent screw of the piston to press the piston. To the surface of the concrete, tighten the air outlet screw, cover the upper cover and tighten the nut, and connect the quick connection of the manual pump and the jack (see the structural diagram for details).
                                              2. Tighten the manual oil return valve clockwise and pull the manual pump handle to increase the oil pressure to 30mpa (the pressure gauge display value). At this time, the pressure of the piston to the bismuth mixture is 3.0mpa.
                                              3. When the oil pressure reaches 30Mpa, immediately open the bleeding valve, and connect the bleeding water into the 1000ml measuring cylinder, and start timing at the same time, and read the bleeding volume V1 and V140 respectively in 10 seconds and 140 seconds, as the calculation of bleeding. The basic data of the rate.
                                              4. After obtaining the data, loosen the oil return valve counterclockwise to depressurize the system, remove the upper cover and the test cylinder, place the test cylinder on the stripper (supplied accessory), and cover the upper cover. Tighten the two nuts. Tighten the return valve in a clockwise direction, pressurize the jack to the cymbal and the piston automatically falls off, remove the upper cover and the test cylinder, loosen the return valve, and manually press the jack piston back, one test is over.
