The tunnel rig produced by Jining Runner Mining Minerals Co., Ltd. is widely used in construction of water conservancy and mines. It is necessary to pay attention to certain skills when purchasing, and the price is not the main factor for purchase. Then we will introduce it to you. What factors should be considered when purchasing.

1, engine power. When we choose tunnel rigs, we need to look at which model is equipped with a larger continuous output power, rather than the maximum intermittent output power or total power, so as to ensure that the rig has a constant load capacity for a long time. It is more important to overcome the resistance during construction, especially when working on complex stratum or rocky strata.

2, torque and rig pull force. The power of the engine determines the actual ability of the drill rig to output the pulling force and torque. The output tension and torque of the drilling rig are a certain proportion. The key is that the ratio of these two parameters should be appropriate. It depends on the rig's walking and rotating transmission methods. The structure and transmission structure determine that the power of the rig is transformed into the rig output capability and output efficiency. The power of the mud pump of some small rigs is also provided by the same engine. The mud pump of a large rig usually has an independent power source.

3, drill pipe size. The drill pipe size is one of the parameters of the tunnel rig.

4, see the manufacturer's level and after-sales service quality. We are the best choice for a formal large company, so that its quality will have a certain guarantee, its after-sales service will be better, and will be easy to solve in the future when we encounter problems.
