Use and maintenance of concrete impermeability meter

Release time: July 1, 2019 popularity: seven

Instructions for concrete impermeability meter:
1. The molding and curing curing of the test piece shall be made of forming die (also known as sub mold) according to the material proportion required by the design, and then shall be maintained and maintained according to the specifications of the department or international standards.

2. Take out the test body from the standard curing room one day before the test, heat the test mold to about 40 ℃, heat the sealing wax until it is completely melted, and then roll the circumference of the test body in the solution for one week (wax is strictly prohibited on both ends of the test body), and then press the wax stained test body into the test mold with a press.

3. Penetration test (1) irrigation: screw off the nut of spray nozzle, open each cut-off door at the same time, place the funnel on the water injection nozzle, fill the water tank, and require the mold test chassis to be filled with water (the function is to remove the air in the pipeline system). At this point, the six doors leading to the mold test can be closed. (2) Installation of test mold: the test mold of sealing test body is firmly fixed on the instrument. (3) Complete the test within 24 hours according to the new specification, for example, the test block is required to press 0. 8 MPa, the lower limit is set to 0. 6 MPa constant pressure for 8 hours, the lower limit is automatically increased to 0. The constant pressure is 7 MPa, the constant pressure is 8 h, and the lower automatic pressure is 0. 8 MPa, and the lower limit was completed after 8 hours. (4) When two end faces of 6 samples are penetrated by pressure water, write down the water pressure as the test pressure value.

Maintenance instructions:

1. Requirements for working environment: the ambient air temperature is 5 ℃ - 45 ℃, and the relative temperature is 80%. It will not work in the environment containing corrosive gas for a long time.

2. The water source should be clean and free of impurities

3. Add the power box oil when leaving the factory, then open the rear box cover and power box cover every six months, change the 20 or 30 mechanical lubricating oil once, and add the oil amount to the central county of the main shaft (about 600ml).

4. Check the water accumulation at the bottom of the power box every six months (this work can be carried out at the same time when changing the oil), and determine whether the sealing ring of the pump is damaged. If it is damaged, it needs to be replaced.

5. If the ambient temperature is lower than 0 ℃, the water should be drained and the safety valve should be emptied of all water sources in the system to avoid freezing and damaging parts of the system.
