Structural design features of grouting pump
(1) Whether it is surrounding rock reinforcement, anchoring support, or roadway repair, the grouting work has great fluidity. The design of the grouting pump adopts explosion-proof and antistatic non-metallic materials, which reduces the weight of the whole machine and is easy to carry. It meets the special working environment requirements of coal mines.
(2) The structure of the whole machine adopts the large piston to directly drive the small piston, and the reversing valve is directly installed on the large piston, which has a compact structure; the two reversing valves adopt a flat sealing structure and are installed on the same shuttle rod with equal strokes. When one valve is opened, the other valve is closed to achieve the purpose of quickly switching the gas on and off.
(3) In order to further improve the sealing reliability, the seals are made of fluororubber materials.
Comprehensive performance analysis of grouting pump
(1) At present, the general grouting pumps in coal mines are powered by explosion-proof motors. Although they have good explosion-proof performance, they are limited by various conditions such as the working environment. Explosion-proof power distribution, invisibly increases the cost of personnel wages.
(2) The fluidity of grouting work is large, especially for the reinforcement of surrounding rock, the fluidity is even greater. Therefore, for the QYB03 grouting pump with a machine weight of only 16kg, it is better than the electric grouting pump with a machine weight of 100~200kg. More flexible and maneuverable.

Shanghai New Samsung Water Supply and Drainage Equipment Co., Ltd.
(3) At present, the roadways of large and medium-sized coal mines in my country are all paved with standard compressed air pipelines, which can meet the work needs of pneumatic grouting without re-laying other power pipelines and no additional investment costs. This provides a good convenience for the large-scale promotion of the QYB03 grouting pump.
The QYB03 portable grouting pump has been proved by years of practice that it has the characteristics of stable and reliable performance, light weight and easy portability. Compared with other types of grouting pumps on the market, it has superior economy and safety.
