The main purpose of the electronic diesel fuel pump seal is to isolate the contact between the oil vapor and the spark. Specific sealing parts include computer control box, computer box and mechanical box separator and explosion-proof junction box.
The above-mentioned sealing parts mainly use rubber strips, rings, etc., by the climate and the impact of the scene, rubber products will appear thermal expansion and contraction, aging cracking to seal failure. Therefore, it should be in accordance with the daily inspection requirements of regular inspection.
1. Computer cover and installed in the panel on the components and the lid between the seal, shall not appear notch, deformation and obvious different thickness.
2. Computer box and mechanical box between the partition cable, pipe through, the seal can not be loose, deformation and fall off, check the feel must be tight, strong.
3. Strong, weak explosion-proof junction box is generally in the bottom of the gas station management software oil vapor often gathered in the place, the seal by the seal and bolts to protect. Therefore, it is necessary to ensure that the seal is complete and bolted.
