down the hole hammer piling


(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

  • One of the primary drivers of fertilizer prices is the cost of raw materials. Fertilizers are primarily made from nitrogen, phosphorus, and potassium, which are derived from natural resources. The prices of these commodities can be affected by mining regulations, energy costs, and geopolitical factors that impact production. For instance, the global demand for potash has increased due to its critical role in crop nutrition, leading to higher prices. Similarly, supply disruptions caused by geopolitical tensions can escalate costs significantly, as seen during conflicts that affect key exporting nations.

  • The antimicrobial activity of sorbic acid and its salts is attributed to their undissociated acid molecule. And therefore their efficacy is pH-dependent. The upper limit for its inhibitory activity is at 6.5 in most applications. The lower the pH, the better as a result of more undissociated sorbic acid. However, this upper limit can be raised in low water activity-solutions.

  • Price is another factor to consider. Denatured alcohol is generally affordable, but prices may vary based on the brand and specific formulation. It's advisable to compare options and look for reputable suppliers to ensure the quality of the product purchased.


  • However, like any additive, E433 may cause allergic reactions in sensitive individuals. Some people may experience gastrointestinal issues or skin irritations as a result of consuming or coming into contact with products containing this emulsifier. Hence, it is essential for consumers to read labels carefully, especially if they have known sensitivities or allergies.


  • Apart from its antimicrobial properties, sorbic acid has antioxidant activities that help protect fats and oils from rancidity, which can further enhance the overall quality and safety of food products. This dual function of inhibiting spoilage and oxidation makes sorbic acid a versatile food preservative.

  • However, as with any food additive, individual sensitivities may vary, and some consumers may experience allergic reactions or gastrointestinal discomfort. For this reason, it is essential for food manufacturers to provide clear labeling and include E575 in their ingredient lists to inform consumers adequately.
