Introduction and working principle of diesel pump
Diesel pump, as a key equipment used for diesel oil transmission, plays an important role in the field of energy transmission. It is mainly used to transport diesel from stationary diesel engines or trucks to other locations or storage tanks, and both small users and large enterprises can benefit from the efficient operation of diesel transfer pumps. Compared with the traditional refueling method of gas stations, diesel pump is not only convenient for transportation, but also has more advantages in cost effectiveness, and its application scenarios are extremely wide, covering 12V, 24V, 220V and other voltage environments, providing a high degree of applicability and indispensable functions for various enterprises and consumers. There are also many electric diesel pumps on the market, further enriching the product types.
Diesel transfer pumps consist of several key components that work together to achieve efficient fuel transfer. The pump body is usually composed of a motor, a gear and a fuel transfer chamber. Multiple seals and valves play a key role in ensuring that the fuel flows in the correct direction and effectively prevents fuel leakage. The hose on the pump is also vital, carrying the fuel from one place to another.
Diesel pump has remarkable functional characteristics, small size, light weight, easy installation and operation, and can be used in various occasions.
Diesel pump is mainly divided into manual and electric two types. Manual pumps rely on human operation, relatively low price and simple operation, but only suitable for short distance fuel pumping; Electric pumps, powered by electricity, can pump fuel over long distances, but at a relatively high cost.
The components of the diesel transfer pump work together to build an efficient fuel delivery system:
Housing: Usually made of metal, it can protect internal components from damage and effectively prevent fuel leakage.
Pump station: The fuel enters the pump body and then passes through different valves to the filtration system, which removes impurities from the fuel and ensures that it meets the standards for use in the vehicle or equipment.
Electric motor: Suction is generated in the system, forming a vacuum environment, and fuel is sucked through the pump station, the power source is electricity or diesel.
Filtration: Before diesel oil enters the storage stage, it passes through a set of filters to ensure that the fuel is pure and free of impurities, avoiding damage to the internal components of the tank.
Pipelines: As a network of pipelines connecting the various parts of the system, fuel is transported between different locations.
Valves: To ensure that certain system components are protected or closed depending on the operating requirements, such as when large amounts of fuel are pumped quickly, valves can limit system suction.
There are various types of diesel delivery pumps, including belt drive pumps, which are driven by an electric motor or a diesel engine and generate suction by supplying power to the belt and offset arm through rotating components; Gear pumps use gears to deliver action and are often used in commercial applications. Centrifugal pumps use centrifugal force to move fluids through the system, making them a popular choice for diesel transfer pumps because of their efficient handling of large amounts of fuel.
It should be noted that diesel transfer pumps are designed specifically for the transfer of diesel fuel and are strictly prohibited for pumping gasoline. This is because gasoline is much more flammable than diesel, with a flash point of about -49 °F (or -45 °C), while common #2 diesel has a flash point of about 125°F to 180°F.
When using diesel pumps, safety measures must be strictly followed:
1. When abnormal sound or smoke occurs on the device, stop the operation immediately to prevent fire.
2. During the refueling process, do not open the cover or perform other work to prevent the risk of fire and avoid inhaling fuel mist that may cause sleepiness or poisoning.
3. When used outdoors, keep away from flammable substances such as paint thinner and gasoline.
4. When used for a long time, pay close attention to the oil temperature and cool it in time.
5. Oil quality will affect the service life of the equipment, it is recommended to use high-quality diesel.
6. The new product should be carefully checked before being used again after the first use or long-term storage.
7. Open the cover after use to allow ventilation inside the pump to avoid long-term storage or hoarding.
8. After refueling, clean up all spills in time and properly dispose of spilled fuel.
