ST 300 Pneumatic Borewell Machine Features:
It is equipped with high-torque hydraulic motor and large-bore hydraulic cylinder for propulsion, and the pump set design is
convenient for maintenance.
independent modular design, and superior maneuverability.
3. The combined positioner can be adjusted and replaced according to different types of drill rods and impactors to ensure
accurate positioning and centering.
bearing capacity and the support height of the outriggers can reach 1.5 meters. The loading and unloading truck can reduce the
cost of hoisting and can be used as a leveling and stable drilling rig during work. 5. The hoisting mechanism facilitates the
lifting of drilling tools, reduces the labor intensity of the operator, and saves time and effort
The correct use and maintenance of the hydraulic system is an important factor to ensure the normal operation of the system and prolong its service life.
(1) Prevent contamination of hydraulic oil. The pollution of hydraulic oil refers to the mixing of air, water, dust from the outside and the formation of insoluble sediment after its own oxidation. The pollution of oil will increase the wear of relative moving parts in hydraulic components, cause the blockage of orifices or the seizure of slide valve pairs, and accelerate the chemical stability of the broken oil, the generation of oxides and the decomposition of organic impurities in the oil. According to the statistics, More than 75% of the faults of the hydraulic system are caused by the oil pollution, so the oil tank should be properly sealed. It is prohibited to use oil resistant seals and rubber hoses. Clean and replace the oil regularly to prevent oil pollution and aging.
(2) Prevent excessive oil temperature. If the oil temperature of the hydraulic system is too high, the viscosity of the oil will decrease, the leakage will increase, and the volumetric efficiency will decrease, resulting in the instability of the oil speed, the deterioration of the oil, the aging of the motorcycle parts, etc. In order to avoid excessive oil temperature, in addition to the recommended hydraulic oil, attention should be paid to the correct oil level in the oil tank to ensure that the system has sufficient circulating cooling oil. At the same time, the water in the cooler shall be sufficient and the pipeline shall be smooth.
