Performance characteristics of down-the-hole drilling rig impactors:1. The contemporary new rock drilling theory is used to design the internal structural dimensions of the impactor, so that the impactor can obtain ideal energy transfer, with large single impact power and fast rock drilling speed.2. Unique taper diameter reduction design.

The impactor of a down-the-hole drill is a key component of the drilling process of a down-the-hole drill. It is used to provide axial reciprocating rock-breaking impact force to the drill bit in order to cool the drill bit and carry rock cuttings, etc. It is also the power fluid of the bottom hole power drill tool.Working principle of the impactor of a down-the-hole drill:The compressed gas enters the impactor through the drill pipe and is then discharged from the drill bit.

Zoucheng Jusheng Mining Machinery Co., Ltd. (Shandong) was established in 2 0 1 8. The company's annual sales are more than 1 5 million US dollars. Before the establishment of the company, we have 1 5 years of experience in equipment sales and service. As one of the excellent authorized agents of  ZEGA  brand mining machinery, we supply  ZEGA  brand mining rigs and air compressors to global customers.  At present, JS Drill has reached long-term cooperation with customers in more than 5 0 countries around the world.
Drilling rig is a complex machine, which consists of machines, units and mechanisms. A drilling rig is a mechanical device that drives drilling tools to drill underground to obtain physical geological data during exploration or development of mineral resources (including solid minerals, liquid minerals, gas minerals, etc.). Also called drilling machine. The main function is to drive the drilling tool to break the rock at the bottom of the hole, and to lower or lift the drilling tool in the hole. It can be used to drill rock cores, ore cores, cuttings, gaseous samples, liquid samples, etc.
If you need a drill rig for various purposes such as drilling a well to obtain natural resources (water, oil, geothermal energy, etc.) building a foundation, drilling holes in a mine, taking samples from the ground.It is necessary to first determine the purpose of the drilling rig and what kind of terrain it will mainly operate on. Depending on the terrain, you can choose different types of drilling rigs: rotary drilling rigs, impact drilling rigs, down-the-hole drilling rigs, top hammer drilling rigs (with high hammer), etc.
A customer from Puerto Rico in the United States asked our company to customize a 200-meter crawler water well drilling rig with diesel power generation/61kw.First, we will draw a rough model according to the customer's requirements, and then the designer will make a prototype based on the graphics. Now it has been made for the customer.
1.  What is the warranty of our machine?Our main machine enjoys a 1 year warranty(except for the hammer), during this time all accessories broken can be changed for a new one.And we provide videos for machine install and operation.2. What is your terms of packing?Generally, we use standard exported wooden case for LCL goods, and fixed well for FCL goods.
