What is the role of pressure limiting valve in the lubrication system?

Pressure limiting valve can limit the oil in the circulating oil, to prevent excessive oil fleeing into the combustion chamber, so that increased fuel consumption, engine work abnormal phenomenon. At the same time also in order to avoid excessive oil pressure, resulting in pipeline and filter blasting. The structure of the pressure limiting valve is a one-way valve that controls the oil pressure by the pressure of the spring. When the oil pressure in the oil path is greater than the spring pressure, the ball opens and some of the oil flows back to the oil pan, so the oil pressure relief. It is generally installed on the oil pump or the main oil gallery.

Automatic 3D Fiber Laser Pipe Cutting Machine

Technical advantages:

1. Excellent and efficient processing: Five-axis linkage of the bus system realizes space leapfrog and flying cutting technology, and improves efficiency by more than 20-50%.

2. Pipe cutting system: user-friendly and easy to operate, with sufficient pipe process database.

3. Special bed design:reinforced integrated welding bed, after annealing and twice aging treatment, with good stability.

4. Simple and convenient maintenance: the front chuck has good sealing performance and is more durable against dust; The rear chuck blows air automatically, and the pipe wall is cleaner.

5. Automatic feeding rack(optional): realize automatic clamping, pushing and accurate feeding with fast cyclic feeding speed.

6. Good quality and high precision: front and rear full stroke precision pneumatic chuck, multi axis linkage at the same time, good cutting effect and high precision.

7. A15: Double chuck short tailing:the cutting head spans from the front to the back of the front chuck and cuts the last workpiece.The tailing ≥ 40mm can save more material costs.

8. Excellent processing performance: it adopts high rigidity thickened bed, with bus pipe cutting system and bus motor which has faster processing speed and higher precision.

9. Slag extraction system (optional): solve the problem that there is no residue on the inner wall of the pipe, eliminating the secondary vibration polishing process.

10. High efficiency feeding system (optional): high rigidity design of feeding rack, stable and fast feeding and refueling, and the cycle time is about 10 seconds.
