General Description:
The internal water pressure testing machine/device special for concrete pipe and reinforced concrete pipe is researched and designed according to <<CONCRETE AND REINFORCED CONCRETE DRAINAGE PIPE>> (GB/T 11836-99), <<TEST METHOD FOR CONCRETE AND REINFORCED CONCRETE DRAINAGE PIPE>> (GB/T 16752-2010), which adopts horizontal structure, mainly used for testing the internal water pressure of the concrete and reinforced concrete drainage pipe.
Main features:
1,The two pieces of blocking plate is like independent trolley, suitable for testing different length(≤5m);
2,Mechanical lifting platform is suitable for testing different diameter pipe;
3,Electric water pump for loading water into pipe, less labour and time, stable pressure-adding;
4,Pressure-adding is adjustable.
5,Pressure value is displayed directly by MPa;
6,Electric contact pressure gauge ensure the stable water pressure, auto stop working, pressure maintenance during testing.
7,High rigidity frame design reduces interference factors to test results;
8,The sealing pressure at both ends of the test piece is reinforced by a hydraulic oil cylinder, the force is applied smoothly, and the sealing performance is excellent;
9,The hydraulic oil source is displayed by a hydraulic meter, which can be maintained when the maximum sealing force is reached, intuitive and controllable.
Technical parameter:
1,Maximum internal pressure: 0.16MPa
2,Maximum pipe length to be tested:5meter;
3,Regulating range of the support: 0-1450mm;
4,Regulating mode of the support: motor-driven;
5,Scale interval value of pressure gauge: 0.005MPa;
6,Precision of pressure display value:≤±1%(prior to 1grade);
7,Pressure-adding mode: motor-driven;
8,Pressure display mode: digital display;
9,Power source:380V±10%,220V±10%;
10,Pressure control mode: hydraulic maintenance
11,Dimension:13000×4000×4000mm;
12,Machine weight: 9000Kg
13,Maximum diameter of the pipe to be tested: 3000mm(300-3000mm);
14,Safety protection:when the pressure value exceed 3% of preset value, the testing will stop automatically.
15,Installation notice: Due to the huge equipment, it is necessary to prepare the foundation in advance on site, and then on-site installation will be carried out, and then painting.(user is required to lift, install the machine).
