Purchasing requirements for hydraulic wrenches.Air impact wrench sale
source:Industry News release time:2021-12-10 Article author:Rosit Popular:Air band saw
In current industrial production, the importance of threaded connection quality has attracted widespread attention. The quality of threaded connection is the basis for ensuring the quality of equipment and the normal operation of equipment. Most threads must be pre-tightened during connection to enhance the connection. Rigidity, tightness, anti-loosening and anti-skid, proper control of pre-tightening force is the key to ensuring the quality of threaded connection. In order to save labor costs and improve production quality, hydraulic wrenches are more and more widely used in industrial and mining enterprises, and the purchase of hydraulic wrenches is becoming more and more common. Now let's talk about the matters needing attention when purchasing hydraulic wrenches.
The first is the preparatory work before purchasing:
1. Bolt specifications
On the front page, you must determine the specifications of the bolts you are using, and then you can know the model of the imported hydraulic wrench you want to buy.
2. Bolt torque
Torque is the most critical parameter for selecting a hydraulic wrench. Different bolts have different torques, the same bolt material has different torques, and the same material has different torques under different working conditions. The bolt torques used in rolling mill equipment and chemical equipment are different, generally The design drawings will give the torque size.
The second is the choice of brand:
Everyone here knows to choose cost-effective products, which can not only meet the needs of production but also achieve the purpose of saving costs, but here I hope that everyone will give priority to choosing products of well-known brands. After all, safety is the first thing in production. .
The last thing is to note:
1. One type of hydraulic wrench can only solve several similar bolts. Generally, it is equipped with 3-4 sleeves. Hydraulic wrenches are not universal wrenches. Many manufacturers' promotional materials deliberately exaggerate the range of bolts and give you more sleeves. , After going back, so many sleeves go back and only sleep, which increases the purchase cost;
https://primacabinets.com/2. For manufacturers with conditions, it is best to use an electric pump with two wrench heads. Using diagonally can improve efficiency and torque more accurately. The cost of one to four is too high;
3. The use of hydraulic wrench should be kept by a dedicated person, used by a dedicated person, and frequently maintained, such as oil change, cleaning, etc., in order to keep the chain in use.
