1. Portable metal detector, convenient to take.
2. It can be recharged. It needs 4-6 hours for charging. (the charger and rechargeable battery are ordered additional)
3. The alarm terms is sound and light alarm simultaneously, or vibration and light alarm simultaneously. You can choose the operate terms optionally.
4. When the low sensitivity on-off is pressed, the metal detector will only alarm when it finds big metal object
5. Holster (for option)
6. Earphome (for option)

Education area: Prevent taking cheat-tool, such as: telephone, electronic dictionary, and so on.

Excavator Cylinder: The hydraulic cylinder is a linear actuator whose output force is proportional to the effective area of the piston and the pressure difference between both sides. ‍Its function is to convert hydraulic energy into mechanical energy. The input of the hydraulic cylinder is the flow and pressure of the fluid, and the output is the linear motion speed and force. The piston of the hydraulic cylinder can complete linear reciprocating motion, and the output linear displacement is limited. The hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy for reciprocating linear motion. The hydraulic cylinder is basically composed of a cylinder tube and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device.

Cylinder maintenance method:

One. The hydraulic oil should be replaced regularly during the use of the cylinder, and the system filter should be cleaned to ensure cleanliness and prolong its service life.
two. Each time the oil cylinder is used, it needs to be fully extended and retracted for 5 strokes and then run with load. Doing so can exhaust the air in the system and preheat the systems, which can effectively avoid the presence of air or water in the system and cause gas explosion (or scorch) in the cylinder body, which will damage the seals and cause leakage in the cylinder. Wait for failure.
three. Control the system temperature. Excessive oil temperature will reduce the service life of the seal. Long-term high oil temperature will cause permanent deformation of the seal or even complete failure.
four. Protect the outer surface of the piston rod to prevent bumps and scratches from damaging the seals. Frequently clean up the mud and sand on the dust ring of the cylinder dynamic seal and the exposed piston rod to prevent difficult-to-clean dirt sticking to the surface of the piston rod Into the inside of the cylinder, damage the piston, cylinder or seal.
Fives. Check the connections of the threads and bolts frequently, and tighten them immediately if they are loose.
six. Frequently lubricate the connecting parts to prevent corrosion or abnormal wear in the absence of oil.
