Interpretation of working principle of dosing metering pump
Dosing metering pump working principle
Dosing metering pump motor driven by the worm and the worm through the worm gear so that the spindle and the eccentric rotation for the rotation, driven by the eccentric tappet in the guide cylinder for reciprocating motion. Together with the diaphragm, the vacuum in the pump cavity is gradually formed by the action of the one-way valve, the suction valve is opened and liquid is sucked in;
When the diaphragm moves forward to the dead point, the suction valve is closed and the discharge valve is opened. The liquid is discharged by the diaphragm. In the pump by adjusting the stroke of a reciprocating work to form a continuous pressure, the amount of liquid discharge.
Wire Mesh Fence
wire mesh fence can installation with squre post, DM post, Pech post, round post, fence panel with curves can make more stable ans sronger.
common color: green RAL6005, black RAL9005, white RAL9010
PVC/PE coated surfacetreatment will with variety colors, it will make Welded Wire Mesh fence looks beautifull and anti-rust.
The advantage of Wire mesh fence
1>Simple structure, easy installation and nice appearance,
2>It is an economical version of the panel system
3>Constructed from a welded mesh panel with longitudinal profiles that forms a rigid fence
4>The fence panel is welded with high quality low carbon steel wire, surface treated by electrostatic polyester powder spray coating over galvanized materials.
5>Then connect the fence panel with post by suitable clips
Surface treatment after welded:
1>Powder spray coated (thickness 0.1mm)
2>PVC/PE dipped coating (thickness 0.8-1.2mm)
3>electro galvanized (zinc thickness : 20-60g/m2)
4>Hot dipped galvanized (zinc thickness : 280-500g/m2)
