Technical performance and structural performance of concrete impermeability meter
Technical performance of concrete impermeability meter Structural principle of concrete impermeability meter Concrete permeation instrument is designed according to the original hydraulic pressure, and the motor is driven by the water pump to connect the pressure vessel, the pressure valve, the control valve, the test socket and the like. The pressure is output from the pump into the pressure vessel and then transferred to the test piece system for loading testing. The pipeline is equipped with an electric contact pressure gauge and an electrical control system. By adjusting the electrical contacts in the electrical contact pressure gauge, the pressure can be tested in a constant pressure range of 0.1 to 4 MPa.

The concrete penetrator is equipped with two kinds of pressurizing functions, electric and manual. Whenever the electrician's control system fails, it can be manually operated (installed on the large belt reel and the spare handle can be used) to maintain the test piece. The continuity of the penetration test.
Concrete penetrators are composed of rack test, pump pressure vessel, control valve, pressure gauge and electrical control. The structure and function of each part are as follows:
1. The concrete anti-seepage test rack is made of high-quality steel. The countertop is made of high-quality cold-rolled steel sheet. It is flat and smooth. The test mold base is fixed on the work surface, and the edge of the seat has undercut grooves. The hole is drilled in the tank, and the water oozing out from the test mold flows back to the water tank from the hole, 6-12 to keep the table surface dry. Neat and durable. The test mold 6-12M bolts are fastened to the test mold base with a special hexagonal tube wrench, and the middle is sealed with a "0" rubber ring.
two. Part of the concrete impermeability pump The water pump is powered by a 90W motor. The pulley and the gear are used for two-pole shifting. The eccentric wheel rotates with the connecting rod and the guide post, thus driving the pump plunger to reciprocate, because the flow of the pump is very small. Therefore, it can be regarded as the static pressure of the test body.
four. The pressure vessel pressure vessel is a large vessel with water storage and can reduce the pressure of the pressurized water. Before the test, the vessel is filled with the nozzle through the water nozzle. After the test is completed, the water in the pressure vessel is discharged through the drain valve. Do as much as five. Concrete anti-seepage instrument electrical control electrical control principle: motor 1M is the power source of the drag pump, through the upper and lower contacts of the electric contact pressure gauge alternately connected, disconnected, (1M) motor start, stop automatic control , so that the water pressure is in a boost state, and sometimes in a steady state.
