Dry maintenance: (close the furnace for more than one month) After the boiler is shut down, the boiler water is released, the internal dirt is completely removed, rinsed, and slightly fired. Then, the 10-13mm block-shaped quick lime is placed in the boiler. Do not allow lime to come into contact with metal. The weight of the quicklime is calculated as 4 kg per cubic meter of boiler volume, and then all manholes, hand holes, and pipe valves are closed. Check every three months. If the lime is broken into powder, it must be replaced. The lime should be taken out when the boiler is re-run. Wet maintenance method: (Stop for less than one month) After the boiler is shut down, the boiler water is released, the internal dirt is completely removed, rinsed, the treated water is refilled, the water is heated to 100 °C, and the water vapor is discharged outside the furnace. Then close all valves. Wet maintenance should not be used in cold climates to prevent the boiler from freezing and damaging the boiler. In addition, the maintenance and maintenance of DZL series steam boilers should strengthen the training and management of the furnace workers, so that the boiler, safe, stable and efficient operation.
A hydraulic tool is a type of tool that uses hydraulic power to perform various tasks. It operates by using fluid pressure to generate force and perform work. The hydraulic power is typically generated by a Hydraulic Pump, which pushes hydraulic fluid through a series of hoses and into the tool.

Hydraulic tools are commonly used in industries such as construction, automotive, and manufacturing. They are known for their ability to provide high levels of force and precision. Some common types of hydraulic tools include hydraulic jacks, hydraulic presses, hydraulic cutters, hydraulic crimpers, and hydraulic torque wrenches.
One of the advantages of hydraulic tools is their ability to generate a large amount of force with relatively small input effort. They can also be operated remotely, allowing for increased safety and convenience. Additionally, hydraulic tools are known for their durability and long lifespan.
However, hydraulic tools require regular maintenance, including checking and replacing hydraulic fluid, as well as inspecting hoses and fittings for any signs of wear or damage. It is also important to follow proper safety procedures when operating hydraulic tools, as they can be powerful and potentially dangerous if used incorrectly.
