High Pressure Grouting Drilling Rig High Pressure Grouting Drilling Rig has excellent technical performance of low energy consumption, high efficiency, convenient transportation and field construction.
The whole vehicle action mechanism is realized by the hydraulic system, and only the source of the wind consumed by the impactor is used in the air compressor. The purchase cost of the whole set of equipment is greatly saved in the selection. The slewing mechanism adopts a new type of motor slewing head, so that it can maintain a strong rotary torque output for open-air blasting large-hole rock drilling operations. When the air compressor is towed, it has mobile flexibility and strong climbing ability, which is suitable for rugged sites. Features of convenient operation and perforation displacement.
The drilling rig has high perforation efficiency, easy maintenance and high reliability. It is an ideal drilling rig for rock drilling operations in mining, highway, water conservancy, and power station construction.

On August 22, some people reported the phone through 12365, reflecting that the water meter purchased by them went too fast and the displayed value was obviously inconsistent with the normal usage. After receiving reports from the people, the Qin Shui quality supervision agency immediately organized law enforcement officers to conduct investigations and verifications. According to the investigation, the water meter was produced by a Jiangxi company and was sold directly to a newly-built district in the county. The law enforcement personnel then randomly sampled the batch of water meters and sent inspection agencies to inspect the water meter's indication error, pressure loss, continuous flow, and static pressure.
The test results show that the error value between the displayed value of the water meter and the specified water quantity exceeds the allowable error range, and the maximum error is as high as -23.6%, which is an unqualified product. At present, 116 unqualified water meters have been sealed up and the quality supervision department has imposed administrative penalties on the offending parties.
Law enforcement officials pointed out that on the one hand, because the gray cast iron contains components that affect water quality, the long-term use of such water meters will affect people's health; on the other hand, when the total table data is greater than the sub-table data, the residents will share the excess water. Fees are skeptical and have buried the danger of disharmony. Law enforcement officials reminded consumers that when purchasing a water meter, you should pay attention to checking the water meter's measuring instrument production license number, the national measurement permit CMC mark, and the number of stamps. After purchase, do not rush to install it. You can send it to the verification agency for testing first, to avoid legality. The rights and interests are damaged.
