What is the reason why the fuel dispenser is too slow? 10

1. The flowmeter is mainly used to measure whether the leather bowl is worn or aged, please check it carefully (professional knowledge is required or a professional person is required, otherwise it is difficult to install it after dismantling.)

2. Oil and gas device, you are likely to be a gasoline gun, gasoline gun in the process of refueling, oil and gas device has been in accordance with the proportion of oil and gas, but some cars are not well vented, a large number of bubbles are produced in the fuel tank when refueling, and the oil and gas device will suck the bubbles up, so they are stored in the head of the oil gun. Disassemble the oil gun, purge it with an air compressor, straighten the oil pipe at the same time, check whether there is any accumulated liquid in the connecting pipe of the oil gun, and if so, control the accumulated liquid downward.

3. The setting of the oil tanker, each fuel dispenser can set the refueling speed, please consult the dealer or manufacturer to set it up and speed up the flow rate, but it should be noted that after the flow rate is modified, it may affect the measurement accuracy of the flow meter, and it is best to recalibrate it once (because you don't know whether the error is positive or negative).

4. Check the filter of the oil engine to see if it has not been replaced for a long time, if it is blocked, please replace it.

Check whether the filter, oil pump, relief valve, and pipeline are blocked, there are many reasons, check them one by one.

First of all, if the oil output of your machine itself is not large, right, then you can't be fast, right, and then the filter element, whether the voltage is operating in the normal range, the machine I bought online before produces 65 liters of oil per minute, or very fast. Petroleum equipment mass store.

One possible reason is that there are many of them, and it is best to contact customer service.

Good evening, dear and happy to answer for you. 1. Check whether the bottom valve of the fuel dispenser is flexible. If the foot valve enters impurities, the foot valve movement is not flexible, and there is a phenomenon of stuck, it may cause the oil pump to be slow to produce oil.

2. Check whether the oil pipeline of the fuel dispenser has a zigzag or high and low. At the highest point of the pipeline, oil and gas are often stayed (because the gas is relatively low in oil density), and it is difficult for the fuel dispenser to exhaust the gas of this kind of pipeline, because there is some gas in the pipeline, the oil flow section will be reduced, causing the fuel dispenser to produce oil slowly, and if this situation is in summer, it will also cause the fuel dispenser to not produce oil. 3. Check whether the oil pipeline of the fuel dispenser is too long.

The standard distance between the oil tank and the fuel dispenser is 30 meters, and the longest distance should not exceed 50 meters. 4. Check whether the filter is blocked. Inside the fuel dispenser, there are at least 3 filter devices, any filter blockage may cause the fuel dispenser to produce oil slowly, the machine vibrates greatly, and some people often ignore the cleaning of 1 or 2 filters, so that the maintenance is in a predicament and helpless.

5. Check whether the oil pump overflow valve is normal. When the hydraulic system reaches a certain pressure, the relief valve is automatically opened, and the seal of the relief valve is not tight, which will cause the oil pump to be slow to produce oil, and in serious cases, the oil pump can not form negative pressure, and the oil dispenser does not produce oil. 6. Check whether the oil outlet valve (Huocheng high-pressure valve, balance valve) can be opened flexibly.

The detergent in the combustible oil composition of the fuel dispenser contains solvents, which will accumulate in the combustion chamber of the machine, and will accumulate over time to form tar, resulting in clogging of the oil pipe and making it impossible to produce oil. If you encounter a situation where the fuel dispenser suddenly does not produce oil, the best thing to do is to stop the fuel dispenser immediately, first check whether the oil volume is sufficient, if it is determined that the oil volume is sufficient, you need to carry out a comprehensive inspection and maintenance of the fuel dispenser, find out the specific problem and then repair.

Summary. Hello dear <>

The reason for the sudden slow refueling of the fuel dispenser is that the oil leakage of the oil pipeline or the loose sealing of the bottom valve will cause the fuel dispenser to jump when lifting the gun; The oil outlet valve is not tightly sealed, which will produce the phenomenon of start-up hops, and the oil outlet valve needs to be checked and cleaned; The use of non-standard hoses when lengthening or replacing the hose of the fuel dispenser at will is also one of the reasons for the number of start-up hops of the fuel dispenser, and the solution is to replace the hose; If the nut fixing the index plate in the sensor box is loose, there will be a start-up hop phenomenon; The newly installed refueling machine or the freshly repaired refueling machine may have a hop count when it is turned on for the first time, which is normal and can be solved by refueling once.

The tubing or grease nipple may become clogged with debris or dirt, causing the oil to flow slower. Insufficient pressure: The oil pump of the fuel dispenser may provide insufficient oil pressure due to low voltage or other reasons, resulting in a slower oil flow.

Fuel dispenser failure: If there is a failure of the oil dispenser itself, such as a problem with the Hannian Chang circuit or a mechanical failure, it may also cause the oil flow to slow down. If the refueling machine suddenly slows down, stop refueling and notify the gas station staff as soon as possible to check the problem.

Summary. Pro, there may be the following reasons for the sudden slow refueling of the refueling machine: 1. The refueling machine itself is faulty, it may be a failure of the circuit board, or a failure of the motor, or a failure of the oil pump, which will lead to a slow refueling speed.

2. There may be dirt in the pipeline of the fuel dispenser, and the dirt in the oil pipe will block the oil pipe, affecting the flow of oil, resulting in a slower refueling speed. 3. There may be oil leakage in the fuel tank of the fuel dispenser, which will affect the flow of oil, resulting in a slower refueling speed. 4. There may be oil scale in the fuel tank of the fuel dispenser, which will affect the flow of oil, resulting in a slower refueling speed.

In addition, the sudden slow refueling of the dispenser may also be due to a malfunction of the dispenser's control system, or the fuel tank capacity of the dispenser is insufficient, or the temperature of the fuel tank of the dispenser is too high, which will cause the refueling speed to be slow.

In short, there are many reasons for the sudden slowness of the fuel dispenser in Jiabo Town, if you encounter this situation, it is recommended that you contact the local fuel dispenser Mu Silver Freight maintenance service provider in time, so as to solve the problem in time.

1.Clogged refueling pipe: Clogged refueling pipe is a common cause of sudden slow refueling in a refueling machine, and foreign objects such as charcoal, dirt or water accumulate in the refueling pipe, which makes the refueling speed of the refueling machine slower.

4.Solenoid valve failure: Solenoid valve is an important component in the refueling process of the refueling machine, due to the importance of controlling the refueling of the refueling machine, if the solenoid valve fails, the refueling speed will suddenly slow down.
