1. The oil in the oil separator should not exceed the middle position of the observation hole, and should not be lower than the position of the fuel pipe tee. Otherwise, the vacuum pump will be damaged.

2. When the outdoor temperature is below 0 °C, apply antifreeze oil. Use 0 to 10 degrees Celsius to use diesel engine oil. If the temperature is above 10 degrees Celsius, replace the gear oil and check to ensure the smooth flow.

3. If the new pump is used for the first time, if the vacuum is not high, the reason is that there is no oil or too little oil in the new pump. When the pump is running, vacuum cannot be generated. The oil cannot be sucked into the pump from the oil separator. The method is to add 1-2 liters of oil to the new pump. If there is oil in the pump, a vacuum can be generated, and the oil can be sucked into the pump from the oil separator to generate a vacuum.

4, the car is pumping 30 to 40 cars for oil change, 50 cars to 60 cars for another one, and then look at the oil in the case of less oil. If the sewage enters the tank, it must be replaced with new oil.

5. If the sewage truck or the suction truck is inadvertently operated during work, the sewage will be sucked into the vacuum pump and installed in the back water vapor separation and oil separation and piping system, causing the whole system to be blocked by dirt. The whole system will The vacuum cannot be formed. In severe cases, the vacuum pump will be damaged. After this happens, the clean suction piping system (including the four-way valve and the water vapor separator) should be completely removed, and the oil separator and the fuel pipe tee and the oil inlet pipe return pipe should be cleaned. Replace contaminated oil and carefully remove contaminants from the vacuum pump. If the oil is not pumped after cleaning, check whether the ball of the water vapor separator and the anti-overflow valve are in the corresponding position (the inside of the anti-overflow valve and the water vapor separator should be at the bottom, and the anti-overflow valve only serves as a protection. The function is not 100% effective. If the bubble inside the tank is too large or there is foreign matter on the anti-overflow valve ball, the anti-overflow valve will not work.) After the car is used for a period of time, check whether the universal joint screw is loose.
