How to eliminate the emergency fault and routine maintenance of small refuelling vehicles

Refueling vehicles are also called mobile refuelling vehicles and are mainly used to provide on-site refueling services for various types of automobiles. Since fueling vehicles are fuel-laden for a long time, they are high-risk vehicles and regular maintenance and repair work is necessary.
1. Refueling chassis maintenance, refueling vehicles generally use Dongfeng, Liberation and Fukuda chassis, need regular visit to Dongfeng, Liberation and Auman service station.
2. The special equipment for refueling trucks. Special equipment for tankers includes tanks, network management systems and power take-off equipment.
3. Every day, the fasteners must be inspected and the grease must be cleaned.
4. Need to detect whether there is oil leakage and leakage in the interface part of the tank before exiting the vehicle. Whether the upper cover is covered as required, the amount of lubricating oil, the amount of fuel oil, cooling water, braking by hands and feet, steering device, instrument, lighting , Tyre pressure, tire nuts, etc.
5. Inspection and monitoring of various items in the refuelling vehicle, including instrumentation, steering system, brake system, engine, chassis, tank and other abnormal sounds and abnormal odors.
6. The following items need to be checked after taking the car: Tire and nut tightening, remove the inclusions in the tire tread, check for oil leakage, water leakage, air leak, check the condition of the leaf spring, if the drive shaft bolt is loose, check the tank Body appearance and pipe network system for tank cars.
Because of the special characteristics of the operation of refueling vehicles, regular and irregular maintenance and maintenance are very necessary and accidents cannot be neglected. The following is a common troubleshooting method summarized by Hubei Chenyang, for reference only.

No.

Refuelling car failure phenomenon

Possible causes of rapid resolution

1

Abnormal suction, no suction or suction

No oil in the pump

Refueling 10L Suction depth exceeds 5m Exceeded the scope of use of the vehicle The ball valve is not open Position adjustment Ball valve switch

2

Vacuum indicates low or no indication

Suction pipe partially sealed

Keep the seal tight

Oil pump impeller clearance increase inspection, repair oil pump vacuum table damage replacement

3

Vacuum indicates high value (4Mpa)

The suction pipe partially obstructs the cleaning filter and cleans the suction pipe

4

Pressure gauge has no value (or lower)

Part of the outlet pipe is not sealed tightly and the sealed tight pressure gauge is damaged and replaced.

5

Abnormal pump

According to the oil pump instructions

6

Power box noise

Car pressure is not enough, the power box is not on file

Pneumatic power take-off box will be sufficient to make the barometer read more than 0.3MPa

Poor air seal, power take off box is not connected

Keep the seal tight

The air chamber is damaged and the power box is not attached

Overhaul chamber

Too little oil in the power take-off box or impurities in the oil or replace the lubricating oil Retrieving, cleaning, replacing worn parts

7

Speed ​​box abnormal noise

Lubricating oil in the gear box is too little or has impurities

Refueling or replacing lubricants Gear box wear and tear Removal, cleaning, replacement of worn parts

8

Tank can't put precipitation

Impurities clog the dust-collecting pipeline. Clean the winter tank with excess water. Freeze or melt the ice with hot air or hot water.

9

The flow machine does not rotate and the working pressure of the oil pump is too high

Impurities stuck in the flowmeter should be disassembled and cleaned. The position of the meshing of the two gears is incorrect. Reinstall the gears with reference to the flowmeter manual.

Rice Cooker

Rice Cooker

A rice cooker or rice steamer is an automated kitchen appliance designed to boil or steam rice. It consists of a heat source, a cooking bowl, and a thermostat. The thermostat measures the temperature of the cooking bowl and controls the heat. Complex rice cookers may have many more sensors and other components, and may be multipurpose. Cooking rice has traditionally required constant attention to ensure the rice was cooked properly, and not burnt. Electric rice cookers automate the process by mechanically or electronically controlling heat and timing, thus freeing up a heating element on the cooking range that had to be otherwise occupied for rice cooking. Although the rice cooker does not necessarily speed up the cooking process, with an electric rice cooker the cook's involvement in cooking rice is reduced to simply measuring the rice, preparing the rice properly and using the correct amount of water. Once the rice cooker is set to cook, the rice will be cooked with no further attention.

Features:

For modern home rice cookers, the smallest single-person model cooks 1 rice cup (180 ml), whereas large models can cook 10 cups. Commercial models can cook 20 or more cups. As a possible source of confusion, model specifications and names may list either cooked or uncooked capacity. Rice roughly doubles in size during cooking; therefore, a 10 cup (uncooked) rice cooker can produce up to 20 cups of cooked rice. The prices vary greatly, depending on the capacity, features, materials used, and the country of origin.

The majority of modern electric rice cookers are equipped with a stay-warm or keep-warm feature, which keeps the rice at an optimal temperature for serving without over-cooking it. Some gas cookers also have electric stay-warm mechanism. However, the usefulness of this feature degrades over time, a microwave may be more energy efficient or better suited to reheat rice that will sit longer than four hours.

Some rice cookers use induction heating, with one or more induction heaters directly warming the pot. This can improve energy efficiency.

Most modern rice cookers use aluminium for the inner cooking bowl. There are some models that use stainless steel instead of aluminium. Various other materials, such as copper, pure carbon, ceramic, and diamond powder coating, may be used for higher heat conductivity or better taste.

The pressure-cooking models can raise the water's boiling point higher, e.g., from 100 °C at 1.0 atm up to about 110 °C at 1.4 atm, which speeds cooking. The pressure-cooking models can also be used in high altitude areas, where the boiling temperature is below 100 Celsius. Pressure cookers are also suitable for cooking brown rice (which contains oils and bran fiber that cook differently from pure white rice starch). Some pressure rice cookers have a varying pressure control mechanism (named the "dual-pressure" method) that creates repeated pressure/release cycles during the cooking.

There also exist mechanisms to collect and return the boiled over liquid to the inner rice bowl.

Many cookers now have microprocessor-controlled cooking cycles, which are often used to adjust for rice and cooking type.

Applications

Rice cookers are typically used for the preparation of plain or lightly seasoned rice. Each rice cooker model may be optimized to cook a certain type of rice best. For example, most Japanese rice cookers are optimized for cooking Japanese rice and may not be the best for other types of rice[citation needed], although cooking time can be lengthened simply by more water.

The typical method of cooking long grain rice is boil-and-strain and/or steaming method. The absorption method used in Japanese rice cookers will produce slightly different texture and taste, usually stickier rice.

Brown rice generally needs longer cooking times than white rice, unless it is broken or flourblasted (which perforates the bran).

Different varieties of rice need different cooking times, depending on their grain size, grain shape, and grain composition. There are three main types of Asian rice: Oryza sativa subsp. indica, i.e., Indian rice (long grain rice, e.g., basmati rice and Thai jasmine rice), O. sativa subsp. javanica, i.e., Java rice (large grain rice) and O. sativa subsp. japonica, i.e., Japanese rice (medium grain rice, e.g., Calrose rice, short grain rice, e.g., most Japanese rice and risotto rice).

African rice, Oryza glaberrima, is an entirely separate species, but can be cooked in the same way. Zizania is not even in the same genus, although it is often called a rice (or "water oats"); it, too, can also be cooked in a rice cooker.

A rice cooker can be used to cook many boiled or steamed granular foods, such as pot barley, bulgar wheat, and dal. Provided the ingredients have similar cooking times, a rice cooker can cook mixtures such as khichdi. Some rice cookers can be used as automated couscoussiers, cooking couscous and a stew simultaneously.
