For the problem of material leakage in hydraulic screen changers, whether it is a belt type hydraulic screen changer or a fast hydraulic screen changer, the first thing to look at is where the material leakage is coming from. 1. Leakage from the connection between the flange and the hydraulic screen changer. This is because during the installation of the hydraulic screen changer, there are impurities on the end face of the connecting ring that have not been cleaned thoroughly, or the bolts of the flange have not been tightened diagonally in sequence, resulting in uneven connection between the flange and the screen changer. After disassembly, clean up the waste at the connection between the hydraulic screen changer and the flange, tighten the bolts diagonally in sequence, and ensure that the gap between the flange and the screen changer is the same.

For the problem of material leakage in hydraulic screen changers, whether it is a belt type hydraulic screen changer or a fast hydraulic screen changer, the first thing to look at is where the material leakage is coming from.

After disassembly, clean up the waste at the connection between the hydraulic screen changer and the flange, tighten the bolts diagonally in sequence, and ensure that the gap between the flange and the screen changer is the same.

2. Leakage at the gap between the heating rings of the hydraulic screen changer. If the pressure sensor hole reserved at the inlet of the hydraulic screen changer is not plugged or the plug is not tightened, simply plug the pressure sensor hole with a plug or tighten the pressure sensor plug.

3. There is material leakage at the connection between the sliding plate of the hydraulic screen changer and the main body of the hydraulic screen changer. There is a quality issue with the assembly of the hydraulic screen changer. There was a material leakage immediately after installation, so it needs to be reassembled at the factory. If there is a material leakage issue during the warranty period, on-site maintenance or factory repair is required. If there is a material leakage again after repair, a new machine will be sent.

4. If there is a leakage problem in the mesh belt automatic screen changer, it is mainly caused by the small or blocked circulating water flow, which cannot cool and seal. Increasing the cooling water flow rate and cleaning the scale in the cooling water circuit inside the screen changer can solve the problem.
