Rotary drilling opportunities to how to solve the problem

Rotary drilling opportunities to how to solve the problem

20 Mar,2018

Rotary drilling rig in the use of a lot of unexpected small problems, if as a novice certainly can not be handy to treat, it also needs long-term accumulation and practice. After all, there are many possible problems, such as falling objects, hole collapse, hole body deviation and other problems. Let's look at all possible problems and solutions of small rotary drilling rig manufacturers. When falling objects, they should be fished quickly with fishing forks, hooks, rope sleeves and other tools. If falling objects have been buried by sediment, mud and sand should be removed according to the above-mentioned items, make the fishing tool touch the falling body before fishing. In any case, it is strictly prohibited for construction personnel to enter the casing

Rotary drilling rig may have some sediment at the bottom of the hole during the hole forming process. This is inevitable and can be said to be a defect of rotary drilling rig. Then why does it have sediment at the bottom of the hole? The main reason is that its construction technology is different. The rotary drilling rig method uses non-circulating mud drilling, so the drilling slag cannot be carried to the ground through the circulation of mud to settle down. Our small rotary drilling rig manufacturers can form a rotary drilling rig for continuous slag discharge. There are several main factors for sediment occurrence. Residue between the bucket teeth of the rotary excavator and the bottom cover of the drilling bucket; The bucket teeth of the small rotary drilling rig are sparsely placed, and the drilling slag flowing between the teeth is not

All the staff who have had mechanical work experience are deeply serious about the wear and tear of machinery. The selection of key parts of machinery directly determines the service life of mechanical equipment. In this regard, small rotary drilling rig manufacturers will introduce how to choose drill bits for rotary drilling rigs. 1. According to the geological conditions, the main function of the drill bit rotary excavator is to form holes on the surface. The working object is rock. Due to the shallow depth of the pile holes under construction, the structure, granularity, porosity, cementation, occurrence and compressive strength of the rock have undergone complex changes due to tectonic movement and natural mechanical and chemical effects. In addition, China has a vast territory.

How to make the power head reducer durable?

How to make the power head reducer durable?

Compared with the sales of piling machinery, the sales volume of power head reducer can reflect its three obvious characteristics: one is the quantity, the other is the quantity, and the other is the quality. The so-called bit quantity refers to the average annual sales of 600, indicating that the power head reducer components play an important role in piling machinery and are the main components in piling machinery. The so-called dosage means that the sales volume of power head reducer is less than the total sales volume of various drilling rigs, which proves that the power head reducer has certain quality in all equipment. Otherwise, it is not resistant to use and will be at least equal to or even greater than the total sales volume of various drilling rigs, refers to the beginning of the power head reducer

Rotary drilling rig is a kind of construction machinery suitable for hole-forming operation in a variety of pile foundation engineering. The power device is the main working mechanism of the rotary drilling rig, and its performance directly affects the performance of the rotary drilling rig. The power device is the power source of the rotary drilling rig, which drives the drill pipe and the drill bit to rotate, and can provide the pressure and lifting force required for drilling. When the power device drives the drill pipe and the drill bit to rotate, the rotating speed and torque can be automatically adjusted according to different soil geological conditions to meet the changing working conditions. Generally, the power unit adopts low speed and high torque operation mode for normal drilling operation. Structural Analysis of 1. Power Plant
