1. If it is found that the corrosion-resistant vacuum pump of the engine in operation leaks, it is not allowed to stop its work immediately, but to keep it at the lowest stable speed. At the same time, add water to the cooling system while discharging water (Note: when opening the filler cap, put a cover above it to prevent being scalded by steam). Cool the engine, drive it slowly for a short time and drive to the nearby area The hidden place shall be excluded.

2. If it is a sudden case of corrosion-resistant vacuum pump shell rupture and water leakage, or corrosion-resistant vacuum pump internal parts damage and loss of pump water function, you can replace the relevant parts, troubleshooting.

3. If the corrosion-resistant vacuum pump is seriously damaged and there is no repair condition on the way, the inlet and outlet pipes of the corrosion-resistant vacuum pump can be directly connected to make full use of the natural circulation of cold and hot water to temporarily keep the engine at normal temperature; or use an inner tube or water bucket as a container to firmly fix it, and then lead out two rubber pipes from the container, one of which is connected to the other On the water inlet of the engine, the other one is connected to the water outlet of the engine, and the other end of the two pipes are inserted into the container, and the rubber hose shall be fixed firmly.

4. If only corrosion-resistant vacuum pump shell cracks and water leakage, the cracks can be treated clean, and then bonded with adhesive. In order to meet the emergency, egg white and cement can be mixed into a sticky mass to smear on the crack, and it can be used after setting for several minutes.

5. In the process of construction machinery running or working, the water seal leakage of corrosion-resistant vacuum pump is also common. As long as there is no water ring damage or swelling deformation, water seal spring force is insufficient or broken, emergency treatment can be carried out. The specific measures for emergency treatment are as follows: if the water seal of corrosion-resistant vacuum pump has slight water leakage due to loose sealing, but the wear is not too serious, a sand cloth can be laid on the glass plate or flat plate, and the sealing plane of the water seal can be polished and leveled; or the bakelite water seal can be turned over and used again. However, it should be noted that the water surface and the contact surface on the corrosion-resistant vacuum pump body should be ground to ensure its sealing performance.
