(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

It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.

Une barre de forage est un long tube en acier qui est utilisé pour transférer la rotation et le couple du moteur de forage au bit de forage. La barre de forage est généralement conique à une extrémité, ce qui lui permet de se connecter à d'autres barres ou à un bit de forage. Les barres de forage sont disponibles dans une variété de tailles et de configurations, en fonction des exigences spécifiques du projet de forage.

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.

  • Overall, half sheet wire racks are more than just simple kitchen tools; they offer a blend of functionality and convenience that caters to both culinary and creative pursuits. Their adaptability makes them a must-have in any household or professional kitchen. From cooling baked treats to roasting vegetables and organizing crafts, these racks enhance efficiency and organization, proving that sometimes, the simplest tools can make the most significant impact.


  • The process of transferring cookies to a cooling rack can be an art in itself. Using a spatula, bakers gently lift each perfectly baked cookie from the baking sheet. The aroma of warm vanilla and chocolate fills the kitchen, creating an inviting atmosphere. As the cookies are nestled on the rack, they begin to cool and firm up while retaining their soft cores—a testament to the baker's skill and timing.

  • A true classic. For die-hard meat-lover fans, there’s almost nothing better than a perfectly seared cut of steak cooked to perfection.

  • However, alongside their benefits, small smokers also come with certain risks that potential buyers should be aware of. First and foremost, cooking with smoke involves the use of wood chips or pellets, which can create hazardous conditions if not monitored closely. Poor ventilation or improper placement can lead to smoke buildup that poses health risks. It is crucial for users to ensure they operate their smokers in well-ventilated areas and adhere to safety guidelines provided by manufacturers.


  • Incorporating a sheet pan with a wire rack into your cooking routine opens up numerous possibilities. For instance, consider preparing a roasted chicken dinner. Place marinated chicken on the wire rack, allowing the fat to drain onto the sheet pan below, and surround it with seasonal vegetables that will soak up the chicken's juices as they roast. The result is a flavorful, satisfying meal that is easy to prepare and clean up.


  • 2. Easy Replenishment When you run low on charcoal mid-cook, the coal basket makes replenishing easy. Instead of scattering new coals throughout the grill, you can simply add them to the basket, maintaining an even temperature and avoiding disruption in cooking.


  • An oven cooling rack, often made of metal and designed with a grid-like structure, serves multiple purposes. Firstly, its primary function is to provide a surface for baked goods to cool after they come out of the oven. When hot items, such as cookies, cakes, or bread, are placed directly on a solid surface, they tend to retain heat and moisture. This can lead to soggy bottoms, which is the opposite of what a successful bake should look like. A cooling rack allows air to circulate freely around the baked goods, promoting even cooling and maintaining that desirable crispy texture.

  • When it comes to the meals you can create, the options are practically limitless. For a classic camping dinner, try preparing a one-pot chili using canned beans, diced tomatoes, seasoned ground meat, and your choice of spices. Simply let it simmer for a couple of hours, and you'll have a wholesome meal ready to serve. For those with a sweet tooth, baking a cake or cobbler is also possible, using ingredients like fruits and cake mix. Just remember, cooking with a tripod camp oven requires patience and a little practice to perfect the technique.


  • When choosing a tray cooling rack, there are a few key features to consider. Look for options that are sturdy and have a raised design to ensure proper airflow. Material matters too; stainless steel racks are durable and corrosion-resistant, making them suitable for regular use. Additionally, some racks come with non-stick coatings, which can further simplify cleanup.
