The following is a brief introduction to let the car owners know something, so that when they find similar phenomena in the future, they can make their own minds, do not worry too much, and make basic judgments through the knowledge they know. (When it is found that the liquid dripping from the chassis is not water, but has a color, smell, or a viscous liquid, professional inspection and maintenance is required.) 1. Greening sprinkler air conditioning system drainage, summer air conditioning system drainage is a normal phenomenon. There are two main reasons: First, due to the high temperature inside the green sprinkler, we need to start the cooling system to reduce the temperature inside the car. At this time, the moisture in the hot air inside the green sprinkler will condense on the surface of the evaporator fins with very low temperature. The plastic housing of the evaporator collects water droplets and drains them out of the vehicle. Second, the low-pressure pipeline of the greening sprinkler air conditioner is not covered with insulating foam. The surface of the pipeline is easy to condense the water in the air, and the water droplets will also condense and collect along the lowest point of the pipeline. The location of the drip water system of the green sprinkler is located in the middle of the front of the car. Therefore, if we stop the green sprinkler for a period of time after driving for a while in the summer, we will find that the position of the chassis in the middle of the car will drip, for a while. A clean and transparent water can be seen on the ground below the Kung Fu car. This is not a problem with the vehicle, but the green water sprinkler air conditioner discharges the water outside the vehicle. 2. Green sprinkler tail silencer and exhaust pipe drip In fact, the drainage phenomenon of the green sprinkler exhaust pipe also indicates that the engine is in good working condition, and the mixed gas is fully burned and the efficiency is high. If you are not at ease, you can check if the antifreeze in the water tank is missing. If there is no shortage, it is normal exhaust pipe drainage, indicating that your car is in good condition. If the water tank often lacks antifreeze and the amount of water discharged is high, it is very likely that the engine cylinder gasket is broken and the engine needs to be inspected and repaired professionally (generally the probability of the latter occurring is negligible). 3. Drainage hole drainage to prevent water accumulation in the body Different oils and antifreezes for sprinklers cannot be mixed. How to ensure the good self-priming performance of the sprinkler pump and how to solve the small pressure of the sprinkler pump: To ensure that the sprinkler pump has good self-priming performance, the following conditions must be met: In the daily work, I encountered the pressure of the sprinkler pump is too small, how can we solve it?

Many green sprinkler owners will find that their car chassis sometimes has dripping. Since most car owners are not familiar with professional car knowledge, they tend to become extremely nervous and worry about what is wrong with their green sprinklers. In fact, the green sprinkler manufacturers have made drainage holes for some parts of the green sprinkler chassis at the beginning of the design, the purpose is to drain the anti-corrosion rust. So what parts of the green sprinkler chassis will have a normal "drainage phenomenon"? 
It is also normal for the silencers and exhaust pipes at the tail of the green sprinkler to drip, and most of them will appear in the winter. Gasoline is injected into the cylinder and mixed with air. After combustion in the combustion chamber, it mainly produces carbon dioxide and water. The water is discharged into the atmosphere in the form of gaseous water vapor at high temperature. Since the silencer is located at the tail of the green sprinkler, the temperature is relatively low, and the water vapor liquefies into liquid water when it is cold. A part of the liquid water is accompanied by the high-speed operation of the engine, and is discharged from the exhaust pipe by the action of the air flow, that is, the exhaust pipe dripping or even spraying water. A part of the liquid water will accumulate in the interior of the muffler multi-chamber. In order to prevent the rust and corrosion of the muffler, the green sprinkler manufacturers have specially made drainage holes at the bottom of the design to accumulate in the muffler. The internal liquid water will be discharged through the drain hole, and the silencer dripping phenomenon will occur. 
In addition to the normal drainage phenomenon of the internal operation system of the air-conditioning system, silencer and exhaust pipe, the green sprinkler is also designed to discharge the accumulated water on the body in the rain and snow. drainage hole. These drain holes include engine compartment drain holes, skylight drain holes, door drain holes, and trunk drain holes. Among them, the engine compartment drainage holes are generally located on both sides of the front windshield wiper. In the rainy days, the water in the skylight flows along the A-column conduit, and the water accumulated in the cabin is merged in the fender and then discharged from the vicinity of the wheel fender. The skylight drain hole is generally located at the four corners of the roof skylight. After the rainwater enters the drain hole, the pipe along the A-pillar/C-pillar is finally discharged from the drain port near the front and rear fenders. The door drain hole is generally hidden under the door sealing strip at the bottom of the door panel, mainly discharging rainwater flowing from the gap between the door and window into the interior of the door. The drain hole of the trunk is generally located below the spare tire. It is mainly used to drain the water in the trunk. Since the water is not in the trunk under normal conditions, the utilization rate of the drain hole is not high, so the manufacturer usually puts the drain hole. Block it and unscrew or pry it open when using it. 
Occasionally, there will be a shortage of antifreeze and oil in the sprinkler. If you don't remember the number of oil added before the sprinkler, don't add new oil easily, because the mixed oil of different labels may form bad. effect. In principle, different base oils and additives contained in engine oils produced by different manufacturers may be incompatible or reacted in mixed use in sprinklers, so different grades of engine oil cannot be mixed.
The correct method is to clear the original oil label of the sprinkler and then select the same oil to add. If the maintenance period of the sprinkler is approaching, then the original oil will be directly discharged and cleaned before infiltrating the new oil.
Different types of antifreeze for sprinklers can't be mixed. Similarly, manufacturers of different types of antifreeze can't be mixed. Mainly because the main technology of antifreeze is anti-corrosion and anti-fouling. The production formulas of different manufacturers are very different, and the additives added are different. Therefore, it is inevitable that there will be incompatibility, and chemical reactions may affect the sprinklers. Therefore, do not mix different types of antifreeze.
1. Before the pump is sprayed, the liquid inventory in the pump must be higher than the pump shaft. Therefore, the pump inlet must be connected with an upwardly bent elbow and then a horizontal tube and quick joint. The quick joint center line must be higher than the pump shaft center. Line 300 mm. 
2. The imported pipeline system must be guaranteed to be airtight and the sealing performance is intact.
3. The suction head of the suction pipe must be submerged under water to prevent air from being drawn into the water pipe.
4. When connecting the outlet pipe to the pump outlet, it must be ensured that the straight pipe length is ≥200 mm and then the elbow is connected.
5. There must be a filter tee at the middle end of the inlet pipe to ensure that there will be no impurities in the pump before the water pump enters the pump.
1. The sprinkler pipe filter is clogged, because the water pumped by the sprinkler pump cannot be all clean tap water, it may be a dirty pool or a pumped water in the pond, so there are too many impurities in the water, and the filter is easy to be mixed. The object is blocked, such as sand, plastic bags, branches and other debris, only need to remove the filter inside the filter tee to clean, to ensure smooth, you can resume normal work, the location of the filter in the sprinkler Pump inlet pipe end.
2. The impeller wears and deforms, causing the sprinkler impeller to rotate normally but cannot enter and exit the water normally. Just replace the new impeller.
3. There is a gap in the pump seal, which causes air to enter, and the pressure of the sprinkler is insufficient. The solution is to carefully check whether the pump in the work has leaking water. 
4. The water pump in the sprinkler pump does not work in water, resulting in the phenomenon that the mechanical seal inside the pump is dry and dry, and the mechanical seal can be replaced.
5. The power of the transmission shaft is insufficient, so that the impeller in the pump does not reach the normal working speed, and the throttle can be increased.
