How to raise the loss of gas stations and what are the reasons for the loss of gas stations

Absolute authority I've studied, but it's really hard to say if it's from **.

Summary. Evaporation loss is the largest type of oil loss, volatility is related to temperature and pressure, the higher the temperature, the faster the evaporation, the greater the oil loss; The higher the pressure, the slower the evaporation and the smaller the loss.

Evaporation loss is the largest type of oil loss, volatility is related to temperature and pressure, the higher the temperature, the faster the evaporation, the greater the oil loss; The higher the pressure of spring town, the slower the evaporation, and the smaller the loss.

The evaporation loss of oil can be roughly divided into three types: natural ventilation loss, "small breathing" loss, and "large breathing" loss.

Natural ventilation loss mostly occurs in the top of the tank, in the cavity of the tank body corrosion perforation or weld holes, fire protection system cracked foam room glass damage, breathing valve liquid closed plate is not tightly covered, hydraulic valve is not filled with oil or insufficient oil seal, oil measuring holes, light transmission holes are not covered, etc.

Because the cause of natural ventilation loss is not only the problem of design and grinding, but also the management problem, so as long as the number of excavation and excavation is strong management, and the equipment is repaired in time, the natural ventilation loss can be avoided.

The time of daylight in the location of the oil is related. The longer the daylight, the more "small breathing" is lost; Otherwise, the loss is less.

What are the measures to control the loss of gas stations: (1) Strengthen the inspection, repair and maintenance of oil storage and oil transportation equipment containers. Related, oil pumps, pipes, valves, crane pipes, tank nozzles, etc., so that there is no leakage, no gas run. The positive and negative pressure of the breathing valve is moderate, the breathing is normal, and the valve operation device is guaranteed to be effective.

Leaky barrels and poor technical condition of the car and ship loading oil; After the oil is loaded, the cherry blossoms are leaking and the leakage is immediately loaded. (2) Strictly implement the operation and management of safety technology. When filling trucks and ships, the safe capacity of the oil tank and the loading height of the vehicle and ship should be strictly controlled, so that there is no oil spillage and no oil.

Splash type is not allowed. When filling to the oil drum, it should be carefully operated to not leak oil When receiving and unloading oil products, the remaining oil at the bottom of the car and ship should be sucked or scraped clean. For used or emptied oil drums, the remaining oil at the bottom of the barrel should be poured and pumped clean.

When cleaning the oil tank, it is necessary to remove the remaining oil from the bottom of the tank. (3) Reasonably arrange the use of oil tanks to reduce evaporation losses. Strengthen the plan management of the use of oil tanks, and try to avoid switching oil tanks.

Rational use of oil tanks, minimize the empty capacity of the oil tank, reduce the heating area of the oil tank and the oil evaporation area. Try to reduce the number of transfers between tanks of the same species, and strive to reduce the loss of large respiration. All necessary transfer and measurement should be carried out as far as possible when the pressure inside and outside the tank is balanced.

Oil depots with frequent sending and receiving business should fix the throughput oil tanks, handle and discuss tank by tank, and try to maintain the relative stability of other oil storage tanks. (4) Expand bulk shipments, carry out direct transportation and "four on" (refineries, platform terminals, vehicles and ships, and warehouses) live broadcast business, try to remove the intermediate links of handling, loading and unloading, and reduce the loss of pump loading, pump unloading and other links. (5) Measures to reduce storage loss of ground tanks.

The surface of the tank is painted with a strong reflective silver-gray paint. Pour water on the top of the tank to cool down and reduce losses. Thermal insulation is installed on the top of the tank.

Build a protective wall. Build a protective wall around the tank to reduce the area of sunlight radiation.

Hello dear. Yes, gas station loss refers to the process of refueling fuels such as gasoline or diesel, part of the fuel is not recorded in the accounting system of the fuel dispenser, called "loss book", which is usually calculated by multiplying the amount of fuel by the loss rate. The attrition rate is usually a decimal place that represents the percentage of fuel that is not recorded.

The gas station loss rate is usually formulated by the local financial department, which stipulates a reasonable range of gas station loss rate. The main causes of loss at gas stations include: improper operation of the fuel dispenser, oil leakage or oil spillage, failure of the accounting system of the fuel dispenser, deterioration or improper storage of the oil, etc.

Therefore, gas stations should strengthen measures such as monitoring and managing the behavior of gas fillers, maintaining fuel dispensers in a timely manner, and standardizing the storage of oil products to reduce the occurrence of loss rate and improve the economic benefits and credibility of gas stations. State nuclear attack.

(1) Check and supervise the delivery density, adjustment coefficient and temperature of the microcomputer at the time of delivery, and see how much error there is after sending a certain amount of oil to the tanker. The premise is that the measurement of the tank truck must be accurate, and then the error rate is calculated to ensure that the oil loss sent to the gas station is controlled.

2) The new station or new oil tank is measured by two sets of methods (ruler method and flow method) at the same time to reduce the error of the oil tank. Re-identification of oil tanks with large errors.

3) The tank truck used must be strictly identified by the Municipal Technical Supervision Bureau to ensure the accuracy of the tank truck volume. The retail company and the fuel depot and the fleet check the delivery volume of each vehicle, and the three parties can sign and approve it before it can be put into use after it is accurate, so as to ensure the accuracy of each vehicle of oil in the oil depot.

3) Establish a good communication relationship with technical supervisors, and try to make the error of the fuel dispenser not lower than that of each identification; Establish a fuel dispenser calibration mechanism, and the retail company will verify the gas station refueling machine at least twice a month. If abnormal profit and loss occurs at the gas station, it should be verified on site in time; Once it is found that the error of the fuel dispenser is large, it should immediately contact the Municipal Technical Supervision Bureau to assist in solving it.

3. Strengthen the training and education of relevant staff and responsible persons, and establish effective management measures and accountability systems.

1) The driver of the tank truck of the fleet should have a high degree of responsibility.

2) Strict business discipline, increase the education of management personnel, strengthen the operating procedures for receiving and unloading oil and the operating procedures of daily, ten-month and monthly inventory. Violations will be dealt with seriously.

3) Improve the sense of responsibility of the relevant personnel, monitor the whole process of each car of oil, once found to be lower than the high line, resolutely refuse to take and unload, and report to the superior supervisor for processing.

5) Once the profit and loss is found to be large during the daily inventory, the reason should be quickly ascertained, and the profit and loss analysis mechanism should be established.

6) The retail center should strengthen the inspection and supervision, and the behavior of not following the operating procedures for receiving and unloading, taking inventory, and making false accounts should be severely punished once found, so as to completely eliminate the occurrence of such phenomena.

Now the gas station basically uses the method of lifting in and out to calculate the purchase and loss, and the loss of storage and distribution in the north in three months may exceed -3 to reach -4 can not be regarded as overconsumption, because it is greatly affected by temperature and volume changes.

The purchase is very important, carefully receive and unload every car to buy, staring at the delivery driver, you must know that it is not easy to make money, the quality of the tanker truck driver is uneven, there is no way you can live in harmony, then be the enemy, stop and measure, unload and get on the car to check, you can't be lazy at all, grasp the purchase management will win half.

Be sure to use someone you trust to be responsible for the measurement work, through daily measurement, early detection of whether there is leakage in the pipeline, whether the oil tank is tilted and trachoma, from all aspects to eliminate the accidental loss of oil.

It's all work experience, **unclear again**.

1 All 1 is oil intake and unloading. (When entering by liters, each oil mill has a different liter and kilogram difference.) There is also unclean oil (you can find a car to unload the oil by yourself, and you can know the answer by measuring kilograms after entering the oil, and unloading kilograms).

3. The density of oil (this can't be helped, you can't always find someone to help check it every time you enter the oil) 4. The industrial and commercial bureau, the people of the Metrology Bureau adjusted it when they checked the fuel dispenser (according to the policy, it is not wrong, but the gas station will lose) (you can check it according to the size of the measuring instrument, first go to other gas stations to try it with the measuring instrument and then try it to you. This possibility is very high, and there is generally a gap between the data of the fuel dispenser they adjust and the actual fuel data).

5. If you have said technical problems, will you understand, find a technician to help you check 1 time You can watch it on the side and ask more. I'll tell you how to check it, and you won't find it either. If you find it, you have to find someone to fix it.

7 weather. It's hot and it's cool. (This is generally known to everyone).

It is usually caused by human error.

Just check as I said, and it's best to check if it's human error first. It's best to check 4 first.

Mainly to pay attention to the oil into some tanker drivers are very unqualified when unloading the oil deliberately parked the tanker on the slope so that the last bit of the base can not be unloaded when the oil is slanted and then the driver himself pumped out and sold This is often one of the reasons for the high fuel consumption Although the landlord said that the measurement is strict when entering the oil, but the driver is black more than 100 liters of oil you can not measure out The other is to check the measurement accuracy of the fuel dispenser Whether there is more oil The specific detection method is to use a 20-liter capacity metering barrel Use a fuel dispenser to put 20 liters of oil into it to see if it is accurate The landlord also said that there will be no human factor, so it may be the two reasons just now.

Are you a state-owned enterprise or an individual, PetroChina has had such a situation for no reason, there is less oil, PetroChina has also had such a thing, the individual will not be such a state-owned enterprise is different, I just became the stationmaster is the same as you, I stand because the staff are old, the staff know more about the refueling machine than I still know, I don't know your situation, first check your machine and people.

Personally, I think there are 3 reasons

1. That is, the oil inlet link, is the sufficient amount of oil inlet insufficient? Is the oil depot oil accurate? Is it clean? What is the transportation loss?

3. The temperature in the tank.

That's all there should be!

Leakage of tanks and pipelines is ruled out.
