Anchor rod trolleys are also called anchoring trolleys in some places, which are very prominent in improving support effect, reducing support cost, speeding up lane speed, reducing auxiliary transportation volume, reducing labor intensity, and improving utilization of roadway section. The superiority. The anchor rig is the key equipment for bolt support, which affects the quality of the bolt support - the orientation, depth, accuracy of the hole and the installation quality of the bolt, as well as the personal safety and labor of the operator. Strength and working conditions, etc.
The perfect combination of modern mine safety and production capacity is the absolute advantage of Sandvik. Its advanced mechanized anchoring operation ensures that each anchor is securely installed and reliable, turning the underground mine site into a safe workplace.
Sandvik launched the new Sandvik 2700 series underground drilling rig in 2015, including a DS2710 anchor rig. This equipment is specially designed for underground hard rock mining requiring high performance and high reliability. It is suitable for 2.7x2.7m roadway. It has excellent cost performance and provides a full range of parts and service support for customers to achieve real peace of mind. Mining. Before the new product debut, the device was first tested in China.
The open phosphate rock is characterized by the instability of the roof, which requires a large number of bolt trolleys for roof support. We all know that the most important basis for measuring the efficiency of the bolt trolley is the speed of the bolt. The faster the speed, the more the hit, the higher the safety of the roof.
In this test, the phosphate-opening bolt with a diameter of 39mm, a length of 1.9m and a square plate size of 150x150mm was used. One hanging net was equipped with 5 anchors, and a total of 1012 were installed. The anchoring capacity of each shift was the highest. Up to 100. After half a year of testing, the results show that the performance of the Sandvik DS2710 bolter is 15% higher than the competition!
After the test, the evaluation of the Sandvik anchor trolley by the user of the Phosphorus is: "The DS2710 bolt trolley is more flexible in 1.6 meters wide and the working performance is close to DS310 and 311."
Since the late 1980s, the opening of phosphorus has introduced the equipment of Sandvik's predecessor, TAMROCK, and has been using Sandvik's DS311 for roadway anchoring. As an old partner for more than 30 years, this time will certainly not let the phosphorus open. Since the DS2710 is aimed at the Chinese market and is produced for Chinese customers, it has the advantage of short delivery time. In addition, the anchoring work cycle is safely performed by a single person and can be installed with bolts of various sizes and common types. The guiding principles for the development of such equipment are maximum operational safety and a safe working environment. The DS2710 uses double propulsion beam work to ensure that each anchor has a short average cycle time and a compact body design that makes the equipment more flexible to operate and allows for greater anchorage.
The protector is set between separator or intake and motor in ESP unit. Except for the connection function, the following is the main feature;
1. Seal the power output of the motor to prevent well fluid from entering into the motor;
2. Balance the pressure between the tube annular room and the inside of motor.
3. Balance the axial force of the shaft and separator shaft.
4. Meet the need of expanding and contracting in motor.
