The hydraulic jack wrench is composed of a hydraulic wrench body, a hydraulic wrench electric pump station, a double high-pressure hose and a high-strength heavy-duty sleeve.

Using a hydraulic wrench

Using a hydraulic wrench can greatly improve work efficiency, but improper operation not only cannot improve production efficiency, but may also damage the wrench itself. So before the hydraulic wrench is officially operated, what preparations should be made? I will give you a detailed introduction below, and I hope it will be of some help to you.

Workers who use hydraulic wrenches for work, the first and often important thing to do before each job is to check the hydraulic wrench itself to see if its components are complete, the links between the components are firm, and the components used for reinforcement Whether the screws become loose, whether the structural parts of the hydraulic wrench are complete or severely deformed, and other changes that seriously affect the work. This work can prevent the leakage of hydraulic jack oil.

Oil pump

Idling hydraulic jack wrench check whether its function still exists, and then check whether the hydraulic oil in the machine is sufficient for the work, if there is a shortage of oil, the work should be carried out before the start of the work. To prevent damage to itself due to lack of oil. Not only must check the hydraulic wrench and oil pump, but also carefully check all the oil pipelines. If the oil leaks, it will cause a series of bad symptoms such as poor work efficiency.

Because of the current globalization of commerce, it is not very difficult to find high-strength materials. However, in order to further improve the strength, it is necessary to adopt heat treatment and surface treatment. The strength of the parts is expected to reach 1000MPa or more without chaos, and The uniformity of material strength is also extremely high.

At present, it is difficult for domestic enterprises to achieve the strength of hydraulic square drive wrench internal parts above 1000MPa. Even if it can be achieved individually, it is difficult to achieve batch stability. It is also necessary to learn more from similar foreign products, and invest more manpower and capital in a relatively long period of time, and conduct more trials and experiments in the aspects of material and heat treatment. The following editor will take you to understand the hydraulic wrench!

Several specifications

Generally, there are several specifications, such as M36, M42, M48. If you don't say how big the nut is, it is the opposite side of the metric bolt and nut accessory sleeve.

The opposite side of the hexagon of the nut of M36 is 55, M42 is 65, and M48 is 75. If the bolt specification span is too large, and the torque span is large, two types of wrenches must be used to pre-tighten these bolts. Bolt specifications and bolt strength grades are the most critical parameters for hydraulic torque wrench selection.

Different bolts have different torques. The same bolt strength grades have different torques. The same bolt strength grades have different torques under different working conditions. They are used in rolling mills. The bolt torque on equipment and chemical equipment is not the same, the general design drawings will give the torque size.
