This product is a high-strength screw made of high-quality alloy steel substrate, with Dacromet coating on the surface, which has excellent corrosion resistance and salt spray resistance, and can be used stably for a long time in outdoor, high humidity and other harsh environments. The tail of the screw is pre-coated with anti-loosening glue, which can maintain stable locking force under vibration conditions after assembly without additional anti-loosening accessories, thus greatly improving assembly efficiency and connection reliability. The products are widely used in automobile, construction machinery, new energy equipment and other fields with strict requirements on fastening stability.

This product is the core precision component of the automobile instrument. It is made of high elastic manganese steel base material through high-precision stamping and precision forming process. The thickness tolerance is controlled within ± 0.01 mm, and the flatness error is less than 0.02 mm, which can ensure the stability of the pointer operation and the accuracy of the reading. It has excellent anti-fatigue performance, can work stably for a long time under complex working conditions such as high and low temperature, vibration and so on, and is suitable for dashboard systems of various passenger cars and commercial vehicles.

This product is a locking and non-loosening nut with mechanical self-locking function. It adopts a special serrated meshing structure, which can form a reliable locking force after tightening. It can still maintain stable connection under complex working conditions such as strong vibration and impact, and effectively solve the problem that traditional nuts are easy to loosen. It is widely used in automobiles, rail transit, engineering machinery and other fields with high requirements for connection reliability, which greatly improves the safety and durability of equipment operation.




Our company is developing a new type of airless supercharger, which is based on the crankcase structure of the oil-free air compressor. That is, the crankshaft part in the crankcase adopts the operation mode of an air compressor, a connecting rod drives a crosshead body, an intermediate packing seal is arranged, the lower part of the crosshead body adopts the lubrication mode of an oil-free air compressor, oxygen is completely separated from a sliding part bearing and the like in the crankcase of the crosshead body at the lower part, that is, the moving part of a compressed oxygen machine body is an independent working chamber, the compressed oxygen is not considered, Oxidation of bearing grease, so that the life of the bearing greatly improved. Due to the adoption of a brand new structure (patented product) and the setting of the middle body packing seal, the oxygen leakage is within 4 ‰, the lateral force is moved to the low temperature area, the exhaust temperature is greatly reduced, and the replacement cycle and the service life of the wearing parts are prolonged. The new machine adopts the middle crosshead structure, which makes the size larger and the noise slightly lower. At the same time, the special structure design can grease the bearing of the moving part of the oxygen compressor without disassembly, which makes the maintenance more convenient. New models of electrical components are used Schneider electrical components, high degree of automation, full display function, to meet the requirements of various control States.

Oil-free lubrication, air cooling plus closed water cooling, reciprocating piston type, integral skid-mounted. Touch screen PLC control, inlet and outlet pressure display, running time display, maintenance cycle prompt, all levels of temperature overtemperature, motor overload, water temperature, cooling water fault rolling alarm prompt, self-contained water tank and circulating pump without external water pipe, filling antifreeze at low temperature.


Steel plate telescopic shield

The ratio of the width to the length after compression should not exceed 3.5: 1, otherwise it is difficult to avoid skew or jamming during expansion and contraction. Each protective cover can not only move together, but also move smoothly and in parallel at high speed. There is no vibration, so the noise is very low. The use of this type of protective cover can prolong the service life of the machine.

Each folded layer of the armor-type stainless steel machine tool protective cover can withstand strong vibration without deformation, and at the same time, it is applied to the bellows at a high temperature of 900 ℃ and still maintains its original state. They support each other and play a role in preventing the penetration of small debris.
