3. Open-air drilling rig: according to the different working mechanism of crushing ore and rock, it is divided into steel rope percussion drill, drilling rig, cone drill and rotary drill. Because of low efficiency, the steel rope percussion drill has been gradually replaced by other drilling RIGS. The drill pipe drives the pneumatic impactor and the drill bit to rotate together, and the piston of the pneumatic impactor is used to impact the drill bit to break the ore and rock, which is usually used in small and medium-sized mines to drill holes with a diameter of 80 to 250 mm.

Low atmospheric pressure on Mars influences many physical and chemical processes. One of the most significant effects is the boiling point of water. In a low-pressure environment, water boils at a much lower temperature. On Mars, if liquid water were to exist on the surface, it would quickly evaporate or freeze due to the low pressure, creating challenges for the search for life.

The DTH hammer operates through compressed air, which is pumped through a series of valves and chambers within the hammer. When the air pressure builds up, it drives a piston that strikes the drill bit, creating a powerful force that breaks the material. This process continues in rapid succession, allowing the drill bit to penetrate the ground efficiently. The design of the DTH hammer allows for a larger drop height of the piston than traditional rotary drills, resulting in higher impact energy and better drilling performance.

Understanding Rubber Slurry Pump Factories A Comprehensive Overview

Die Herstellung von Sandpumpen ist ein spezialisierter Bereich der Maschinenbauindustrie, der sowohl technisches Know-how als auch innovative Fertigungstechnologien erfordert. Sandpumpen sind unerlässlich für verschiedene Anwendungen, einschließlich Bauwesen, Bergbau, und Umweltschutz. Dieser Artikel widmet sich den Herstellern von Sandpumpen, den Technologien, die sie einsetzen, und den Herausforderungen, die sie bewältigen müssen.

(1) When using the drilling rig to drill, the driver should be placed in the drilling position, so that the front end is against the rock, and the distribution should be careful to let the drilling rig move forward, so that the drill bit touches the rock; When opening the hole, first quietly let the drilling rig drive, when the drill rod is in place in the rock, it is allocated to the full open position.
(2) Before starting the drilling rig, check whether the charging pressure of the accumulator is normal; Check whether the scouring water pressure and the lubricating air pressure can be; Check whether there is sufficient lubricating oil in the lubricator, and whether the oil supply is appropriate; Check the reverse tendency of the oil pump motor. (3) If the drilling rig cannot open the hole smoothly, it should first assign the rock drill to retreat, and then let the rock drill move forward to open the hole from the beginning.
(4) When replacing the drill bit, the drill bit should be gently pressed against the rock, so that the motor of the drill can be reversed to complete the sensitive unloading head.
(5) The inspection of hydraulic components can only be prevented under the condition of pole cleaning, and after the connecting tissue is removed, it must be quickly plugged with the cleaning tightly matched plug. Before the repaired rock drill is used from scratch, it is necessary to circulate the hydraulic oil into the oil circuit to wash the components of the hydraulic system.
(6) The oil level and oil supply of the lubricator should be checked regularly; The gear with reverse structure is regularly filled with high-temperature grease; Check the oil level in the lubricating oil tank regularly and remove the dirt in the oil tank

Rubber-lined pumps are specifically engineered with an inner lining made of high-quality rubber. This lining acts as a protective barrier between the pump components and the fluids being transferred. The primary reason for using rubber as a lining material is its excellent resistance to abrasion, corrosion, and wear. Compared to traditional metal pumps, rubber-lined pumps can significantly extend the lifespan of pump components, reducing maintenance costs and downtime.
