Do new mine owners often cause mining excavators with breaker to frequently "strike" due to improper operation or neglect of maintenance? This article summarizes 3 fatal operation taboos + 5 core maintenance tips to help you avoid failure traps, and also reveals how Hengwang equipment uses design to reduce "human error risks".
3 operation taboos: The most common "pits" for newbies
Taboo 1: Dry firing the breaker —— The "invisible killer" of the hydraulic system
During dry firing, the breaker piston hits the drill rod at high speed; without rock buffering, it will cause high temperature of hydraulic oil and wear of seals. A new mine owner once spent $20,000 on hydraulic system maintenance due to 3 dry firing incidents!
Correct approach: Confirm the rock contact surface before operation; after starting the breaker, immediately lightly press the drill rod to fit the rock to reduce the probability of dry firing. Hengwang mining excavators with breaker is equipped with a standard hydraulic buffer valve, which automatically reduces the impact force during dry firing to protect the service life of components.
Taboo 2: Mixing hydraulic oils —— A "sharp drop" in oil performance
Hydraulic oils of different grades vary greatly in viscosity and wear resistance; mixing them will cause oil emulsification and seal swelling. A mine damaged its hydraulic pump within 1 month due to mixing ISO 46 and ISO 68 hydraulic oils.
Correct approach: Strictly use the specified grade in the equipment manual (e.g., Hengwang mining excavators with breaker recommends ISO 46 anti-wear hydraulic oil); test the oil quality every 200 hours, and replace it immediately if turbid.
Taboo 3: Overload operation —— The cost of the machine "forcing through"
Continuous excavation of rocks with hardness >15MPa or single lifting overload will cause boom deformation and motor overheating. A newbie overloaded to catch up with the schedule, resulting in cracked boom welds and 1 week of downtime for maintenance.
Correct approach: Monitor the load through the equipment instrument (Hengwang mining excavators with breaker is equipped with an intelligent load display, which alarms when overloaded), and reasonably distribute the operation intensity.
5 maintenance tips: Let mining excavators with breaker "get sick less and work more"
l"3-step inspection" before startup: Check hydraulic oil level (must be between upper and lower limits), accessory connecting pins (no looseness), and whether there is leakage in pipelines (focus on joints).
lRegular "oil change" for hydraulic oil: Replace hydraulic oil + filter every 500 hours (the original filter of Hengwang mining excavators with breaker has a filtration accuracy of 3μm, reducing impurity wear).
l"Lubrication bonus" for accessories: Apply molybdenum disulfide grease to the contact area between the drill rod and the breaker every shift to reduce metal friction loss.
l"Timely cooling" for heat dissipation: Clean the radiator filter after operation (especially in dusty mines) to avoid high-temperature oxidation of hydraulic oil (Hengwang mining excavators with breaker has 30% higher heat dissipation efficiency).
lMonthly "professional physical examination": Contact Hengwang engineers to test the hydraulic system pressure and boom weld strength to troubleshoot hidden dangers in advance.
