The mortar permeameter can detect the weak points of the crushing and the hidden dangers at the bottom in time, which can guide the project to speed up the progress and ensure the quality. The comparison between the mortar permeameter and the ring cutter method shortens the cycle and saves a lot of manpower and material resources. The operation is very simple. As long as you drill a hole in the working surface or dig the 1/4 soil layer and insert the instrument vertically, you can test the instrument. It is most suitable for layering and layering inspection of the fill, and also for quality supervision. The station and the supervision company can sample any layer, and the probe can be specially extended to 1.5 meters. The properties of the mortar are basically the same as those of concrete. For certain special-purpose mortars, such as waterproof mortars, the impermeability requirements are also required, that is, the mortar has the property of resisting the penetration of pressurized water.
Mortar permeation instrument maintenance and maintenance requirements:
1. For the working environment, the ambient temperature is required to be 5 ° C - 45 ° C relative humidity < 80%; do not work in a corrosive atmosphere for a long time.
2. The water source should be clean and free of impurities.
3. The power box oil has been added at the factory. Open the rear cover and power box cover every six months to replace the No. 20 or No. 30 mechanical lubricant.
4. Check the bottom of the power box for water storage every six months. This work can be carried out at the same time when changing oil, and it is determined whether the pump seal is damaged. If it is damaged, it needs to be replaced.
5. If the ambient temperature is close to 0 °C, drain the water and the pressure relief valve will vent all the water in the system to prevent the ice from damaging the parts of the system.
