How to replace hydraulic oil in rolling groove oil pump - roll grooving machine 12inch- vedio

If the rolling groove machine has been used for a long time and the oil pressure is insufficient, it is necessary to replace the hydraulic oil in the oil pump. So how to replace it? Taking rolling groove machine STG2A as an example, the specific method is as follows,

1. In order to prevent oil from overflowing and dirtying the machine during oil change, it is recommended to first remove the oil pump assembly from the machine. The disassembly method of the oil pump is as follows:

2. If you want to remove the entire cylinder from the power head, first apply pressure to move the slider to the lower position, loosen the 2 piston retaining ring screws on the piston retaining ring (Figure 1), and then loosen the 10 inner screws on the pump base. Hexagonal screw M12 (Figure 2) can detach the entire cylinder from the power head.

3. Unscrew the oil drain plug screw under the oil pump (Figure 3), and use a container to collect the dirty hydraulic oil. After cleaning, cover and drain the oil plug.

4. Wipe off any dirt near the filling plug ((Figure 3) on the oil pump, then remove the filling plug and add hydraulic oil (while adding, slowly shake the oil pump handle to help increase the filling speed). After filling up the oil, cover the oil plug and install the oil pump back on the machine.

Wide range of applications of rolling groove machines

Rolling groove machine is an important mechanical equipment widely used in industrial production. Its main function is to create grooves of various shapes and sizes on the surface of metal pipes, plates or other workpieces. This precision machining technology plays a key role in many industries.

• Pipe and vessel manufacturing

Roll groovers are most widely used in the pipe and container manufacturing industry. Metal pipes and plates are the main materials for manufacturing various types of pipes, containers, tanks and other structural parts. Through rolling groove processing, various groove shapes can be produced on the surface of pipes and plates, which are used for the connection and reinforcement of pipes, as well as the sealing and positioning of containers.

Taking petrochemical companies as an example, they widely use rolling groove machines to create threaded grooves on large-diameter pipelines to achieve rapid threaded connections of pipe sections. This not only greatly improves the efficiency of pipeline installation, but also ensures the reliability and sealing of pipeline connections. Rolling groove machines also play an important role in the manufacturing of large storage tanks. By rolling various positioning grooves and reinforcing grooves on the surface of the tank, it not only enhances the overall structural strength, but also provides accurate positioning basis for subsequent installation and assembly.

• Machine made

Rolling groove machines are also widely used in the field of machinery manufacturing. Various metal parts, such as bearing seats, couplings, gears, etc., need to be positioned and connected using grooves of different shapes and sizes during the assembly process. The rolling groove machine can quickly and efficiently produce the various groove shapes required on the surface of these parts, greatly improving assembly efficiency.

Taking the automotive industry as an example, roll groove processing technology is widely used in modern automobile body structures. By rolling out various reinforcing rib grooves on the metal sheet, it not only improves the overall rigidity and impact resistance of the body, but also reduces the weight of the entire vehicle. In recent years, some new energy vehicle manufacturers have applied roll groove technology to the manufacturing of key structural parts such as battery brackets and motor brackets, giving full play to its advantages in enhancing structural strength and reducing weight.

• Building Decoration

Rolling groove machines also play an important role in the field of architectural decoration. While modern buildings pursue beauty and elegance, they also pay more and more attention to the facade decoration effect. The rolling groove machine can produce various exquisite groove textures on metal sheets, which can be used for decoration of exterior walls, roofs and other parts of buildings.

Taking a high-end residential project as an example, the construction company used a rolling groove machine to create a unique groove pattern on the aluminum alloy plate, creating a layered facade effect. This not only greatly enhances the visual impact of the building, but also increases the overall sense of class. At the same time, this kind of metal plate decoration also has good weather resistance and anti-corrosion properties, effectively extending the service life of the building.

• Electrical equipment manufacturing

Rolling groove machines are also widely used in power equipment manufacturing. Key components such as transformer casings and switch cabinet casings require the use of roll groove technology to create groove structures with good electrical conductivity.

Taking a large transformer manufacturer as an example, they used a rolling groove machine to produce precise conductive channels on the transformer housing plate. This not only greatly improves the electrical conductivity of the entire machine, but also significantly reduces the overall weight of the casing. Compared with traditional welding or stamping processes, the rolling groove process can complete this key manufacturing link with higher efficiency and better cost performance.

• Home appliance manufacturing

Even in the field of home appliance manufacturing, rolling groove machines play an important role. Roll groove processing technology is widely used in the shells and internal bracket structures of large home appliances such as refrigerators and washing machines.

Take a well-known refrigerator manufacturer as an example. They use a rolling groove machine to create exquisite textured grooves on the refrigerator shell panels, which not only improves the visual effect of the product, but also enhances the rigidity of the overall structure. Rolling groovers also play a key role in the manufacture of internal support structures. By rolling out various functional grooves on the metal plate, the load-bearing capacity of the bracket is greatly improved, and the total weight of the whole machine is also reduced.

Successful cases of rolling groove machine application

Let’s take a look at several successful cases of rolling groove machine applications:

• In 2019, a well-known automobile manufacturer adopted advanced rolling groove processing technology when developing a new generation of models. By rolling precise reinforcement grooves on the body frame plates, they successfully developed a lighter and more rigid all-aluminum alloy body structure. This not only greatly improves the fuel economy of the vehicle, but also significantly enhances the passive safety performance. The project ultimately received widespread acclaim within the industry.
• In 2021, when a well-known architectural decoration company was decorating the facade of a high-end office building, it used a groove rolling machine to produce a visually impactful groove pattern on aluminum alloy plates. This unique decorative technique not only greatly improves the overall grade of the building, but also adds a new landscape element to the entire city skyline. The project was ultimately highly recognized by the local government and was listed as a demonstration project for promotion.
• In 2022, a well-known domestic power equipment manufacturer made full use of roll groove processing technology when developing new transformer products. They used a rolling groove machine to create efficient conductive channels on the transformer housing steel plate, which not only greatly improved the conductive performance of the entire machine, but also significantly reduced the overall weight. Compared with traditional processes, this rolling groove process shows obvious advantages in terms of manufacturing efficiency and cost control. This product stood out in the subsequent market competition and became the company's star product.

To sum up, rolling groove machines play an indispensable role in pipe containers, machinery manufacturing, architectural decoration, electrical equipment, home appliance manufacturing and other fields. With the continuous advancement of industrial technology, I believe that the application prospects of rolling groove machines will be broader.
