Common fault elimination method of agricultural carburetor

As a precision mechanical device, the carburetor is a very important part for the agricultural machinery engine. Once the carburetor fails, the agricultural machinery will not be used. 1. No idling speed, poor atomization of the mixed gas, increased fuel consumption or no oil. This is due to the lack of regular cleaning and maintenance, resulting in serious fouling, so that the measuring hole, oil channel is not smooth, oil supply is blocked. 2. The acceleration pump tie rod is worn and deformed, which affects the normal operation of the sound again, and deteriorates the engine's power and the economy of small and medium loads. 3. The acceleration nozzle is blocked, the steel ball of the immersion oil valve is stuck by dirt or the filter screen of the acceleration pump is blocked, resulting in poor acceleration or difficulty in starting the cold car. 4. The mating surfaces of the upper, middle and lower bodies of the carburetor are deformed, and oil or air leakage occurs during operation, which causes a decrease in power and an increase in fuel consumption. In this case, the mating surface of the carburetor can be ground and installed. The oil inlet needle valve of the carburetor float chamber is not closed tightly, and the right side is too high, so it should be replaced in time. 5. The float spring is too soft or too hard, causing unstable control of the oil level in the float chamber, and "choking" will occur when the car is driving on uneven roads. It is necessary to replace the appropriate float spring in time. Once the carburetor fails, we must solve the fault in time to avoid the trouble for the use of agricultural machinery.

How long is the carburetor life?

The life of the carburetor is generally 3 to 5 years. 1. The function of the carburetor is to mix a certain amount of gasoline with gas to make the car engine run normally; 2. As a high-precision mechanical equipment, it uses the kinetic energy of the inhaled air to complete the atomization of gasoline. The carburetor is a mechanical device that mixes a certain proportion of gasoline and gas under the action of a vacuum pump formed by the car engine. The carburetor is a high-precision mechanical device that uses the kinetic energy of the inhaled air to complete the atomization of gasoline. The complete assembly of the carburetor includes the starting assembly, the idle assembly, the medium load assembly, the full load assembly and the acceleration assembly. It will automatically prepare the corresponding concentration and export the corresponding amount of mixed gas according to the requirements of different operating conditions of the automobile engine. Because the mixed gas is evenly mixed, it also has the actual effect of atomizing fuel, so that all mechanical equipment can operate normally. Under normal circumstances, the carburetor is a reusable fuel supply system, and its service life is basically the same as that of the entire vehicle. The carburetor naturally does not need to be replaced during scrapping, but it must be cleaned regularly, otherwise it will affect the starting performance and acceleration performance of the motorcycle.

Carburetor cleaner life tips to share

Carburetor cleaning agent is a solvent aerosol, which mainly dissolves the carbon deposits and colloids in the carburetor in the past, including metal scale. It has a dissolving effect on carbon deposits and a certain dissolving effect on metals. It is feasible to use carburetor cleaning agent when there is oil on the surface, and the volatilization speed is very fast and will not corrode the engine, however, if the engine or oil seal is completely invaded into the carburetor cleaning agent, it will corrode and swell the rubber parts. The main purpose of carburetor cleaning agent is to clean the oil circuit, remove carbon deposits and residues Carburetor cleaning operation. 1. Clean the throttle: Remove the engine trim cover, remove the throttle, and use the carburetor cleaner to clean it, dry it with a cotton cloth and install it. Cleaning the throttle is basically every time we go to the 4S shop maintenance staff will advise us to do so. Under normal circumstances, the cleaning cycle of the throttle valve is 20000 kilometers, and the charges of 4S shops vary greatly depending on the brand and model, ranging from 200 yuan to 800 yuan. In fact, we can do it yourself DIY cleaning throttle, so you can save this not a small cost. Because the process of cleaning the throttle is very simple and the cost is very low, you only need to buy a bottle of Hongfu carburetor cleaner for 10 yuan. 2. Clean the carbon deposits inside the engine: Open the oil cap, pour the whole can of detergent (mixed with old oil), close the oil cap, and turn off the engine after 10 minutes of ignition and idling. Clean the carbon deposits inside the engine, and the detergent dissolves the deposits such as sludge, colloid, moisture and metal debris inside the engine, and can reduce the pollution of new engine oil and extend the service life of the engine. Its cleaning cycle is generally once every 30000 kilometers. The cleaning method for carbon deposits inside the engine is also very simple. You only need to add a bottle of engine internal cleaning agent to the oil port before maintenance, and run it at idle speed for about 10 minutes, and then immediately Maintain and replace the oil filter. 3. Clean the carbon deposit in the oil circuit: Before refueling, add the whole bottle of fuel additive to the fuel tank. Look at the instructions. How many liters is your car's fuel tank? Generally, a bottle of fuel additive is used for a 50-80 liter fuel tank. Cleaning carbon deposits in the oil circuit includes cleaning fuel injectors, combustion chambers, spark plugs, throttle valves and other parts. The purpose is to solve the problems such as insufficient horsepower, fuel consumption, panting, poor acceleration or difficulty in starting caused by carbon deposits, colloids and dirt in the oil circuit system. Cleaning these does not require any disassembly, as long as the car's fuel tank is regularly added to the special cleaning type fuel additive can achieve a good cleaning effect. Buy a bottle of air intake system cleaner, pour it into the liquid storage tank of the special cleaning equipment, connect it to the air intake system, and use vacuum to suck the cleaner into the air intake road to achieve the cleaning purpose. Cleaning the carbon deposits in the intake system mainly refers to cleaning the carbon deposits inside the intake duct and intake manifold. Its purpose is to remove carbon deposits in the intake system, increase intake air flow and speed, and reduce engine jitter and idling instability. Generally, 4S shops or repair shops will use the method of hanging bottles to drive the air intake cleaning fluid into the air intake pipe, and the cost is quite high. However, Hongfu's suggestion is to minimize the number of such cleaning, and the general cycle is about 60000 kilometers. Because of the disadvantages of this kind of cleaning, although part of the carbon deposits that have been cleaned will be discharged through the engine, there will always be a part of the carbon deposits intercepted by the three-way catalytic converter, which is easy to block the three-way system, so the number of cleaning should not be too much.

Reasons for high fuel consumption of carburetor and troubleshooting methods

1. Oil leakage of carburetor 2. Partial blockage of air volume holes of various oil systems Reason: Partial blockage of the air volume holes of each oil system will cause the oil supply of the carburetor to be too thick and cause fuel consumption to increase. Exclusion method: according to the aforementioned carburetor cleaning method can be cleaned. 3. Starting enrichment device is not closed tightly See the previous section for reasons and troubleshooting for lax shutdown of the starter enrichment device. 4. The outer diameter of the main oil needle decreases after wear, and the main nozzle hole is too large after wear Reason: The above-mentioned parts are worn out due to long-term high-speed scouring of impurities contained in gasoline during use, which reduces the outer diameter of the main oil needle and the main nozzle hole is too large, resulting in an increase in fuel supply and fuel consumption. Exclusion method: replace the new measuring hole
