Concrete drilling core machine installation
After the drill bit is in the hole position, lift the three walking wheels to let the base fall to the ground. When the hole is drilled and the concrete strength is not high, the rig can be fixed by the weight of the rig. If the hole diameter is large and the rig's own weight cannot stabilize the rig, heavy objects (such as sand bags, etc.) can be placed on the chassis. Iron blocks, concrete blocks, etc.) Fix or hit two expansion bolts and press rods (such as channel steel) to fix the drill. The drill should be fixed firmly and must not be shaken, otherwise the drilling operation cannot be performed normally.
Concrete drilling core machine operation instructions:
1. When drilling, ensure that the feed rate is uniform, about 3~5cm/min. If the drill bit is found to be stuck, the feed speed can be reduced appropriately. If necessary, the drill bit can be lifted for a while, then slowly drilled. Avoid hard drilling so as not to damage the drill bit and the machine.
2. The R&D and production unit of the electric drilling core machine must be maintained in the whole drilling process.
3. At the end of the drilling, the machine can only be stopped when the drill is released from the workpiece.
4. During the drilling process, it should not be overloaded. When the motor temperature exceeds 70 °C, (hand feel hot), the loading force should be reduced, and the new drill bit should be replaced.
Concrete drilling core machine maintenance:
1. Regularly check the joints of the components and adjust them in time if loose.
2. When the drill is installed, add lithium grease to the two threads.
3. Change the R&D and production unit of lithium-based grease electric drilling core machine in the gearbox every six months.
4. After the drilling is completed, scrub all parts of the rig and add lubricant to the column and rack.
Intermediate – Intermediate: A material produced during a drug substance processing step that must undergo further molecular modification or refinement to become a drug substance. Intermediates may or may not be isolated. Intermediates are the key products of the previous process of making APIs, which are different in structure from APIs.
for example:
Amoxicillin capsules are called preparations, amoxicillin is called API, and 6-APA is called intermediate.
Ceftriaxone sodium powder is called preparation, sterile ceftriaxone sodium is called API, and 7-ACA is called intermediate.
Our company specializes in providing key intermediates for various APIs
Intermediate is a very important type of fine chemical products. Its essence is a type of "semi-finished product", which is an intermediate product in the production of certain products. For example, if a product is to be produced, it can be produced from intermediates, saving costs and reducing It is widely used in the synthesis of medicines, pesticides, coatings, dyes and spices. In the field of medicine, intermediates are an important link in the industrial chain of the pharmaceutical industry. They are used for some chemical raw materials or chemical products in the process of drug synthesis. In a word, they are used to produce APIs.
