The push rod of a mist cannon machine determines the accuracy and stability of spray angle adjustment. Electric push rods and hydraulic push rods have significant differences in applicable scenarios due to different power principles. Choosing the wrong one can easily lead to frequent failures or cost waste, so precise matching is required from 3 core dimensions.
Electric push rods are driven by motors, with a thrust usually ranging from 500-3000N. They are suitable for small and medium-sized mist cannon machines (range ≤ 50 meters), such as municipal road dust suppression and small workshop dust control. Their operating noise is below 60 decibels, and no regular hydraulic oil addition is needed, making maintenance simple. Hydraulic push rods, relying on hydraulic systems, can achieve a thrust of 5000-20000N. They can drive 100-meter-level explosion-proof mist cannon machines to operate stably in heavy-load scenarios like mines and coal sheds. Even in environments with dense dust and strong vibration, they can maintain precise angle adjustment.
Electric push rods have many internal motors and circuits. If they are in high-humidity and dusty environments (such as water parks and mine crushing areas) for a long time, short circuits and jamming failures are prone to occur. Hydraulic push rods adopt a fully sealed oil circuit design, with a waterproof rating of up to IP67, which can resist water mist erosion and dust accumulation. When used in open-air operations in rainy areas or high-humidity workshops, their failure rate is 70% lower than that of electric push rods.
The initial purchase cost of electric push rods is 30%-50% lower than that of hydraulic push rods, making them suitable for scenarios with limited budgets and low usage frequency (such as seasonal cooling projects). However, the service life of hydraulic push rods is 8-10 years, twice that of electric push rods, and their energy consumption is 15% lower than that of electric push rods. For 24-hour continuous operation scenarios like mines and large coal sheds, long-term use can save more than 50% of comprehensive costs.
There is no need to blindly pursue “high performance” when selecting push rods for mist cannon machines. It is only necessary to make a comprehensive judgment based on working condition intensity, environmental conditions and service cycle: choose electric push rods for light load, dry conditions and short-term use, and hydraulic push rods for heavy load, harsh environments and long-term use. Only in this way can the mist cannon machine stably exert its dust control effect.
