ZYM handheld floating liquid coal drill

Hand-held floating liquid coal drill
The series of hand-held hydraulic coal drills are floating liquid hydraulic coal drills, which include a coal drill joint, a coupling and a special emulsion hydraulic drive connected by the coupling. Mechanism and the flow adjustment switch, operating handle and other components connected to it.
This emulsion hydraulic coal drill uses the emulsion provided by the emulsion pump station as power. It has a compact structure, small size, light weight, low noise, small flow pulsation, stable operation, can start high-speed drilling at low speed, stepless speed regulation, and has dual switches. The function can be used in wet and dry operations. It is safe and reliable. The connection is very convenient. Special materials and processes are used to prevent rust. The safety performance is significantly improved compared to electric coal drills.
The series of hand-held hydraulic coal drills are widely used in wet drilling of coal seams and soft rocks under various conditions. They solve the problems of difficulty in wet drilling of coal and easy explosion-prone operation and maintenance, and can dig beams for mining working faces. It is an ideal tool for drilling holes in coal mining working faces.
1. Main features of the series of handheld hydraulic coal drills:
The drill itself does not have a power supply and is safe and efficient. It is especially suitable for use in mines with high gas and coal dust explosion risks
Drilling The speed is fast and the average time is faster than that of coal electric drills. The problem of difficult drilling
Compared with coal-fired power generation, there is no need to install power supply lines, electrical equipment and dust-proof pipelines
Small size, light weight, simple structure, and convenient operation and maintenance can greatly reduce the labor intensity of workers. .
2. The working principle of the series of hand-held hydraulic coal drills:
The hydraulic coal drill uses the emulsion pump station with external injection of a single hydraulic pillar on the blasting working face as the power source to convert the hydraulic energy into a torque output mode. Carry out drilling. Part of the emulsification passes through the hollow drill pipe to the drill bit to achieve wet drilling. If a liquid return pipeline is installed, the liquid return can be returned to the emulsion tank for continued use
