Maintenance standards are crucial for ensuring the longevity and performance of agricultural machinery. For tractors, the primary goal is to eliminate the "three leaks"—oil, water, and air. All seals, including oil and water seals, should be in good condition, and all joints must be properly tightened. The "four cleans" include clean oil, clean water, clean air, and a clean machine. To achieve the "five good" conditions: proper adjustment of gaps, pressure, and travel; adequate lubrication with the right oil level and sufficient grease injection; secure fastening with correct torque on all threaded connections to avoid over-tightening or loosening; functional instruments with accurate readings; and well-maintained electrical systems with no open circuits or short circuits.
For agricultural implements such as plows, hoes, and seeders, maintenance standards focus on correct installation and adjustment, ensuring there is no deformation. Fasteners must be firmly secured, and reliable lubrication is essential to prevent dry friction. All parts should be complete, and the overall technical condition must be in good working order.
Operating standards are equally important. Operators should be professional, precise, and cautious. This includes "one specialization," meaning full concentration during field operations, maintaining a straight path, and making timely and accurate adjustments to farming tools. "Two accuracy" refers to correct meter readings and coordinated hand and foot movements. "Three slow" means starting farm tools slowly, driving slowly downhill, taking care when turning, and reducing speed when passing through villages, towns, or bridges. "Four bans" include prohibiting long-term overload operations, high-speed towing of implements, unauthorized disassembly or adjustments, and allowing untrained or unqualified personnel to operate the equipment.
Storage standards are also vital for long-term preservation. Agricultural machines should be stored in a dedicated warehouse or parking area, managed by trained personnel if left for extended periods. The storage location must be free of weeds and standing water. The storage environment should be clean, dry, coated, cushioned, and fully stocked—meaning the machine is clean inside and out, free from oil stains, neatly parked, and with working parts coated in waste oil. Racks should be painted or treated to prevent rust. Implements should be elevated off the ground, and all parts should remain intact and undamaged. Valuable components that will not be used for a long time should be removed and stored separately.
In addition, diesel fuel must follow strict handling procedures: three filters (filtering the fuel when transferring from the tanker to the tank, from the tank to the engine, and from the fuel line to the pump), two precipitation steps (allowing 96 hours of settling in the tank and 48 hours in the drum), and one sealing step—ensuring the tank is sealed after refueling to prevent contamination and moisture ingress.
This classification mainly includes the aluminum low-pressure casting Machinery Parts using in auto area.
From the part, we can easily find that the parts have a lot of features of big cavities, so the part will have big potential risk of mold release problem, if so, the part may happen to be deform, sticking to the mold etc, especially when the part sticking to the mold, if no clear in time, while next shot, the mold may be destroyed while clamping.
