How to prevent Trenchless Drilling Machine from leaking oil?

1. Check the sealing condition: Check the connection of the hydraulic pipeline regularly for leakage, especially the seals of the hydraulic system, such as the cylinder, hydraulic motor, joints and other parts.
2. Check wear and looseness: Check the degree of wear and looseness of the equipment, especially the bearing area, friction area and connection area. During the inspection, confirm whether there is a problem by knocking and listening to the sound. If a problem is found, the cause should be found out in time and further repaired.
3. Maintenance of hydraulic actuators: Regular maintenance of hydraulic actuators such as power heads, power supply parts, clamping parts and cylinder lifting parts. Pay attention to the lubrication of the gears in the gearbox, and observe the lubricating oil level at the same time to ensure its operation at any time.
4. Maintenance of hydraulic power control system: The hydraulic power control system is the core link of the maintenance of the entire horizontal directional drilling equipment, mainly providing hydraulic power for each component. The fuel quality, model and fuel regulator of the engine should be checked regularly for strict quality grading to ensure the safety of the air filter.
5. Maintenance of hydraulic oil circuit: The maintenance of hydraulic oil circuit should start with the cause of hydraulic oil contamination. Once hydraulic oil enters the hydraulic system, it will cause great harm to hydraulic parts. Once dirt penetrates, the valve core and valve body should be maintained in coordination.
6. Check for oil leakage at the joint of the hydraulic oil pump: to prevent the oil pipe from bursting due to excessive local pressure at the joint of the discharge pipe caused by unreasonable operation. The oil temperature of the control system is usually controlled at around 60°C. Once the temperature is overheated, the viscosity and volume of the oil may decrease, resulting in mechanical wear and aging of parts.
7. Regularly replace hydraulic oil and filter: every three months of work, check whether the hydraulic oil meets the standard requirements, and replace the hydraulic oil and filter as needed. After the first 75 hours of work, the hydraulic oil return filter, oil replenishment filter and pipeline filter related filter elements need to be replaced every 250 hours thereafter.
8. Use suitable hydraulic oil: The hydraulic oil tank should be filled with L-HM46 anti-wear hydraulic oil. If the ambient temperature is below 5°C, it is recommended to use L-HM32 anti-wear hydraulic oil. When the ambient temperature is below -10℃, please consult a professional company.
