1. Technical innovation for high temperature climate
- Intelligent temperature control system:
- Develop an advanced intelligent temperature control system that can monitor the temperature of the engine, hydraulic system and key electrical components in real time. When the temperature approaches the critical value, the system automatically adjusts the working state of the equipment, such as reducing the engine speed or reducing the load of the hydraulic system to prevent overheating. For example, by installing a high-precision temperature sensor in the engine coolant circulation system, when the temperature reaches 90-95℃ (different equipment may vary slightly), the system automatically adjusts the speed of the cooling fan to speed up and enhance the heat dissipation effect.
- The intelligent temperature control system can also be combined with remote monitoring technology to transmit the temperature data of the equipment to the operator's mobile device or control center in real time. In this way, even if the operator is not next to the equipment, he can understand the temperature of the equipment in time and take measures in advance, such as arranging equipment rest or adjusting the construction plan.
- Application of high temperature resistant materials:
- Use high temperature resistant sealing materials and lubricants in key parts of the engine and hydraulic system. For example, the use of high temperature resistant sealing materials such as fluororubber can effectively prevent leakage problems caused by aging and deformation of seals at high temperatures. At the same time, choose hydraulic oil with good high-temperature performance, which has a high flash point and oxidation stability, can maintain good performance in high-temperature environments, and reduce system failures caused by the decline of hydraulic oil performance.
- For the outer surface of the equipment, use reflective heat-insulating coatings. This coating can reflect infrared and ultraviolet rays in sunlight and reduce the heat absorbed by the equipment. For example, nano-ceramic reflective heat-insulating coatings can effectively reduce the surface temperature of the equipment. In a high-temperature environment, the surface temperature of the equipment can be reduced by about 10-15℃.
- Efficient heat dissipation structure design:
- Optimize the heat dissipation structure of the equipment and increase the heat dissipation area and ventilation channel of the radiator. For example, a fin-type radiator design is used to increase the contact area with the air and improve the heat dissipation efficiency. At the same time, reasonable vents and air guides are designed on the equipment casing, and the natural wind or forced ventilation devices (such as fans) generated when the equipment is running are used to guide the cold air to flow through the key heating components and take away the heat.
- For the hydraulic system, an independent hydraulic oil heat dissipation circuit is designed to dissipate the heat of the hydraulic oil through a special cooler. The cooler can be water-cooled or air-cooled, and can be flexibly selected according to the actual construction environment and equipment requirements.
2. Technical innovation for low temperature climate
- Fast preheating technology:
- Develop efficient engine preheating system, such as the combination of electric heating plug and intake preheater. The electric heating plug can directly heat the air in the engine cylinder, while the intake preheater preheats the cold air entering the engine. Before starting, the controller automatically starts the preheating program, which can preheat the engine to the appropriate starting temperature (such as 30-40℃) in a low temperature environment of -20℃ in just 5-8 minutes.
- For hydraulic systems and working parts, use oil heating technology. Install heating devices, such as oil heaters, in the lubrication system of hydraulic oil tanks and working parts. Before starting the equipment, heat the hydraulic oil and lubricating oil to achieve the appropriate working viscosity, reduce the resistance when the equipment is started, and improve the starting efficiency of the equipment.
- Optimization of low temperature adaptability components:
- Design the battery for low temperature adaptability, such as using cold-resistant batteries or adding special electrolyte additives inside the battery to improve the discharge performance of the battery at low temperatures. At the same time, optimize the insulation structure of the battery, wrap the battery with insulation materials to reduce heat loss.
- Choose tire or track materials suitable for low temperature environment. At low temperatures, ordinary rubber will become hard and brittle, affecting the driving performance and comfort of the equipment. Using cold-resistant rubber materials to make tires or tracks can ensure good elasticity and grip in low temperature environments.
- Automatic snow and ice removal function:
- Equip the equipment with automated snow and ice removal devices. For example, heating wires are installed on the working parts of the equipment such as scrapers and spiral spreaders. When the equipment is started, the heating wires automatically work to melt the snow and ice on the working parts to prevent them from affecting the normal operation of the working parts.
- Set up a small snow blowing device around the walking device (tires or tracks) of the equipment, and use compressed air or fans to blow the snow away from the walking device to ensure that the equipment can travel normally on snowy or icy roads.
3. Technical innovation for humid climates
- Upgrade of waterproof sealing technology:
- Adopt higher-level waterproof sealing technology, such as IP67 or IP68 level sealing standards (IP level is the international code used to identify the protection level, and the larger the number, the higher the protection level). For key components such as electrical control cabinets and motors, use sealing rubber rings, sealing pads and sealants for multiple sealing to prevent water, dust and moisture from entering.
- Develop waterproof and breathable membranes to cover the vents and parts of the equipment that may be flooded. This membrane allows air to circulate but prevents water from entering, balancing the air pressure inside the equipment while keeping the equipment dry. For example, using a waterproof and breathable membrane on the housing of the laser transmitter and receiver can prevent water from entering without affecting the transmission of the signal.
- Dehumidification and drying system:
- Install a dehumidification and drying system that can dehumidify the air inside the equipment using desiccant or the principle of refrigeration and dehumidification. For example, a small dehumidifier is installed in the cab or electrical control cabinet of the equipment. When the humidity sensor detects that the air humidity exceeds the set value (such as 70% - 80%), the dehumidifier automatically works to reduce the air humidity to an appropriate range.
- For hydraulic systems and lubricating oil systems, vacuum drying technology is used. During equipment maintenance, the water in the system is extracted by a vacuum pump to ensure the dryness and purity of the oil and extend the service life of the oil.
- Intelligent monitoring and protection against rust:
- Develop an intelligent monitoring system for anti-rust, and monitor the rust of components in real time by installing corrosion sensors on key metal components of the equipment. The sensor can detect parameters such as humidity, salinity and pH on the metal surface. When these parameters reach critical values that may cause rust, the system will sound an alarm.
- Based on the monitoring data, a device for intelligently spraying rust inhibitors is used. When the system determines that rust prevention treatment is required, it automatically sprays rust inhibitors on the parts that may rust, or protects the metal parts of the equipment through electrochemical protection methods, such as cathodic protection technology, to prevent rust.
