Problems solved by technology
[0002] There are three ways to control the speed of geological engineering drilling rigs: 1. Mechanical control, which is composed of a gear transmission box and a clutch. The gear transmits kinetic energy to drive the grinding disc and then drive the drill pipe to achieve drilling. 2. Hydraulic valve control. The hydraulic system consists of pumps, valves, oil cylinders, motors and fuel tanks. The speed of the actuator is controlled by the hydraulic valve. The disadvantage of this method is that the oil leakage is serious and the handle is controlled. 3. Pilot hydraulic control, the hydraulic system is divided into two parts, the main circuit and the pilot circuit, the pilot oil is controlled by the handle valve, and then the pilot oil controls the main hydraulic valve. The disadvantage of this method is that the oil circuit is complicated and installation Time-consuming and laborious to disassemble
