Summary of information:We have more than ten years of experience in screw industry production, the main products are: copper embedded, supply f...

1. The twisted screw should be considered according to the actual inner diameter of the barrel, and the outer diameter deviation of the new screw should be given according to the normal clearance with the barrel. 2. After the thread surface with the reduced diameter of the worn screw is treated, the wear-resistant tungsten carbide alloy is thermally sprayed, and then ground to size. 3. Surfacing wear-resistant tungsten carbide alloy on the thread part of the worn screw. According to the degree of screw wear, surfacing welding is 1~2mm thick, and then the screw is ground and processed to size. This wear-resistant tungsten carbide alloy is composed of materials such as C, Cr, Vi, Co, W and B, which increases the wear resistance and corrosion resistance of the screw. 4. The bottom diameter of the screw is repaired by electroplating hard chromium. Chromium is also a wear-resistant and corrosion-resistant metal, but the hard chromium layer is easier to fall off.

Usually, the pumped storage unit adjusts the opening of the guide vane through the movable guide vane to control the power generation output and the pumping head of the unit. The torque of the guide vane rotation depends on the relay to act on the control ring, and the torque is transmitted to the guide vane rotating shaft through the connecting rod and the arm. The torque transmission between the crank arm and the rotating shaft all acts on the pin located between them. When the unit is overhauled, it is necessary to remove the pin between the arm and the rotating shaft of the guide vane in advance when it comes to the replacement of the guide vane. However, due to the special position of the pin and the limited inspection space, the conventional method is not only time-consuming and laborious, but also has the risk of damaging the pin. Maintenance work brings inconvenience.

Nuts on the market still have certain defects. The bolts rely on multiple nuts against each other to prevent loosening. This method cannot be completely locked. The bolts are easily loosened when subjected to huge pressure and vibration, which hides potential safety hazards and has a protective effect. Bad problem, for this, we propose a nut with self-locking function

The beneficial effects of Guangdong Yueluo Hardware Industry Co., Ltd. are: in Guangdong Yueluo Hardware Industry Co., Ltd., the rivet fixing mechanism is used to temporarily fix and position the rivet, and the pressure cylinder is used to drive the movement of the final shaft, so that the insertion nozzle can be Insert the rivet located in the rivet fixing mechanism into the product. Guangdong Yueluo Hardware Industry Co., Ltd. adopts mechanical drive and transmission, which has a high degree of automation and high work efficiency.

rivet is a nail-shaped object used to join two parts or components with a through hole and a cap on one end. In riveting, the riveted parts are connected by their own deformation or interference. There are many types of rivets, and they are not limited to the form. The existing switch is not easy to fix, and needs to be supported by others during installation, which leads to waste of labor, and at the same time, it is easy to damage the hands of the supporting personnel. The existing device driving method is relatively laborious. Some devices require rivets of different lengths in different thicknesses, and cannot be assembled by themselves of the same type.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: elastic nuts, isolation columns, plum hole screws and bolts, box button storage boxes and other products, we can provide you with suitable fastener solutions for you .
