Due to different manufacturers, there may be differences in the appearance of mortar grouting machines. In terms of structure, they are basically the same, consisting of hydraulic devices, pump shells, pump shafts, sealing devices, and axial force balancing devices. 1. Hydraulic device The hydraulic device is the core part of the mortar grouting machine, and […]
The high-pressure grouting machine for mining should be fixed in a flat position as much as possible to prevent the oil and slurry pipes from being distorted or discounted. The slurry pipes should be minimized as much as possible, and their safe distance should not exceed one meter. Regularly maintain the fuel tank mesh and […]
Selection method of grouting machine When choosing a grouting machine, users must pay attention to it. The machine is used on the construction site, and if they buy counterfeit and inferior products, it will not be worth the loss. It will affect the progress of the project and may even cause accidents. The personal safety […]
Composition structure of hydraulic mortar grouting machine Due to different manufacturers, there may be differences in the appearance of mortar grouting machines. In terms of structure, they are basically the same, consisting of hydraulic devices, pump shells, pump shafts, sealing devices, and axial force balancing devices. 1. Hydraulic device The hydraulic device is the core […]
When purchasing grouting pumps, users need to understand the performance of the machine, and equipment with high cost-effectiveness will not have problems during grouting work. 1、 The grouting equipment should match the geological conditions of the construction site during operation, fully consider the rotational performance of the equipment, and leave appropriate room for improvement. 2、 […]
1、 Drilling machinery Drilling machinery mainly includes three categories: rotary, rotary impact, and impact. Currently, rotary drilling rigs are commonly used, followed by rotary impact drilling rigs. Pure impact drilling rigs are used very well. Two grouting machinery The main types of grouting machinery include grouting machines, slurry mixers, grouting machine recorders, etc. 1. Grouting […]
During the grouting process, improper operation of the grouting machine can easily cause blockage of the conveying pipeline? What is the reason for this? Technicians believe that under normal circumstances, the slurry forms a columnar fluid in the center of the conveying pipeline of the grouting machine, flowing in a suspended state. There is a […]
It is very simple and convenient to use gas drainage hole packer. Connect the joint of gas drainage hole packer and the watercourse or air pump on the operation spot. Then connect the steel tube and gas drainage tube. And insert the gas drainage hole packer into the drilling hole totally. The rubber hose of gas […]
Usage: The sealing device used for coal seam water injection increases the moisture content of the coal body, moistens the coal particles, reduces the hardness of the coal seam, and promotes the softening of the coal seam by injecting water into the coal seam; The dust production of the upward coal seam plays a significant […]
Mechanical grouting packer in the grouting hole, by mechanical pressure to make the rubber plug (seal) transverse, and the hole wall is tight, the grouting hole is divided into upper and lower two sections, so that the grouting of the lower section can be put into the grout crack water-bearing rock, but not from the rubber […]
