The hydraulic oils commonly used in photovoltaic pile drivers mainly include anti-wear hydraulic oil, low-temperature hydraulic oil, etc. Due to different climatic conditions in different regions, there are certain differences in the selection of hydraulic oil. The following are the specific situations:
High temperature areas
Applicable hydraulic oil types: usually choose ISO 46 anti-wear hydraulic oil or other hydraulic oil with higher viscosity.
Analysis of the cause: The ambient temperature in high-temperature areas is high. Hydraulic oil with higher viscosity can maintain better stability and performance at high temperatures, which can reduce the risk of leakage caused by the thinning of hydraulic oil at high temperatures, and provide good lubrication, cooling and sealing for the hydraulic system of the pile driver, ensuring the normal operation of the system in high-temperature environments, such as desert areas in the Middle East.
Cold Regions
Applicable hydraulic oil types: Generally recommended to use L-HV low temperature hydraulic oil or L-HS ultra-low temperature hydraulic oil
Cause analysis: In cold regions, such as China's northeast region and parts of Russia, the winter temperature often drops to very low levels. The viscosity of ordinary hydraulic oil will increase significantly at low temperatures, and may even solidify, making it difficult to start the hydraulic system. , poor operation and other problems. Low-temperature hydraulic oil has a low pour point and good low-temperature fluidity, and can quickly reach various lubrication parts in a low-temperature environment, ensuring that the hydraulic system starts and works normally under cold conditions.
Temperate regions
Applicable hydraulic oil types: ISO 32 or ISO 46 anti-wear hydraulic oil are more commonly used.
Analysis of the reasons: The climate in temperate zones is relatively mild, and the temperature range is relatively small. These two types of hydraulic oils can basically meet the use needs of temperate zones most of the time. ISO 32 hydraulic oil has a lower viscosity and better fluidity in seasons or environments with slightly lower temperatures. It is suitable for some photovoltaic pile drivers that require higher response speeds; ISO 46 hydraulic oil can provide better stability and lubrication performance in high temperatures in summer or when the equipment is under heavy load.
High humidity areas
Applicable hydraulic oil types: anti-wear hydraulic oil with good anti-emulsification and anti-rust properties, such as Mobil DTE 20 series.
Cause analysis: In high humidity areas, such as Jiangnan region in China and some countries in Southeast Asia, the moisture content in the air is high, and the hydraulic oil is easily contaminated by moisture and emulsified and deteriorated, affecting the normal operation of the hydraulic system. Therefore, it is necessary to use hydraulic oil with good anti-emulsification properties, which can quickly separate from water to prevent the occurrence of emulsification. At the same time, good rust resistance can protect the metal parts of the hydraulic system from corrosion.
A down-the-hole drill is a type of c that performs underground operations in a rotating manner. It can perform underground drilling operations through its own rotation and propulsion, and is commonly used in construction engineering, geological exploration, mining and other fields. This article will introduce the principle, structure and application field of down-the-hole drill in detail.
The principle of down-the-hole drilling rigs is mainly based on the rotation and thrust of the drill rod. The drill rod breaks the soil layer by rotating; at the same time, the drill rod pushes down, and the high-pressure gas released from the inside of the drill rod to the bottom of the hole (this requires an air compressor) discharges the broken soil and rocks upward. This continues until the predetermined drilling depth is reached. Down-the-hole drilling rigs are usually composed of a drill rod, a drill bit, a power unit and a control system, among which the power unit can be a hydraulic system or an electric motor, and the control system is responsible for realizing the accurate operation of the drilling rig.
Down-the-hole drills are highly flexible and adaptable, and are suitable for operations under a variety of geological conditions. Drill rods and drill bits of different diameters and lengths can be selected as needed to meet different hole-opening requirements. Down-the-hole drills can also perform core sampling and well logging.
Down-the-hole drills are widely used in the field of construction engineering. They can be used to drill holes in pile foundation construction and provide stable foundation support for large buildings. At the same time, down-the-hole drills also play an important role in the construction of underground pipelines, bridge supports, tunnels and other structures. Their efficient operating capabilities and accurate positioning technology make the construction process safer and more precise.
Down-the-hole drills are also widely used in geological exploration and mining. In geological exploration, it is often necessary to obtain underground samples and data to evaluate the reserves and mining value of mineral resources, and down-the-hole drills can accurately obtain core samples.
Down-the-hole drills have important application value in the fields of construction engineering, geological exploration and mining. With its efficient operation capability and accurate positioning technology, it provides great convenience for people's work. With the continuous advancement of science and technology, it is believed that down-the-hole drills will continue to grow and play an important role in more fields.
