Cam pump working principle and application advantages (Figure)

Rotary cam pump is self-priming, valveless, positive row of pumps. Two synchronous rotor side by side toward each other, respectively, clockwise and counterclockwise rotation to form a drainage chamber. Open the pump inlet cavity filled with the material delivered. These materials are displaced in the direction of volume flow to the discharge end. Displacement and speed related, and the flow is reversible. The rotor is aligned and almost perfectly sealed when stopped. Pump delivery up to 1300 m³ / h (3500 usgpm) Pump lift up to 120 m (174 psi) The advantages of a rotary lobe pump are: 1. Online service (ie without dismantling the pipe, the drive can be repaired in place , Very convenient) 2, accessories are very cheap, the price is only about 1/4 screw pump, and replacement is also very simple. 3, special energy-saving, to achieve the same flow and lift than other pumps about 30% energy saving.

A typical version of an overhead garage door used in the past would have been built as a one-piece panel.The panel was mounted on each side with unequal parallelogram style hinge lifting mechanism. Newer versions of overhead garage doors are now generally built from several panels hinged together that roll along a system of tracks guided by rollers. The door is balanced by either a torsion spring system or a pair of extension springs.A remote controlled motorized mechanism for opening garage doors adds convenience, safety, and security

• Aluminum garage doors are low-cost, light, rust-proof, and feature low-maintenance. They are prone to denting because aluminum is not strong and they are energy-inefficient since aluminum is a highly conductivematerial.

• Fiberglass and vinyl garage doors are composite units, combining a steel core behind a fiberglass or vinyl skin. They have also polyurethane insulated base sections, or other type of foam insulation. These premium doors can match steel garage doors, and be a realistic imitation of wood (namely fiberglass units), but they may be more expensive than steel units.

• Steel doors have become common and are available in a variety of sizes and styles, provide strength and security, are cost-competitive, and may have optional insulating value. Extra strength is available with two or three layers of galvanized steel with a low gauge number (23-24 gauge steel panels).

• Wood garage doors offer aesthetic appeal, but they are high-maintenance and may be expensive. Low-priced wood garage doors may warp and break easily.
