Descrição do produto
Gear Pumps
Gear pumps (with external teeth) are positive displacement (or fixed displacement) pumps with a simple working and economic structure. The displacement volume of hydraulic gear pumps can be from about 1 to 200 milliliters. They have lower volumetric efficiency than gear pumps, vane pumps, and piston pumps. These pumps generate pressure by the meshing of the gear teeth, pushing the fluid around the gears to apply the pressure to the outlet side.
Some gear pumps can be much noisier than other types, but modern models of gear pumps are much more reliable and quieter than older ones. This is partly due to designs including split gears, helical gear teeth, and higher quality tooth formations that mesh and unmesh more smoothly. These features reduce pressure ripple and related detrimental issues.
Another strength of the gear pump is that severe failure is much less than most other hydraulic pump types because the gears constantly wear down the housing and main bushings. It decreases the volumetric efficiency of the pump until it is completely useless. This often causes the unit to stop working or break down.
Características
⑴ Simple structure and cheap price
⑵ Low work requirements and wide application
⑶ The end caps and the inter-tooth grooves of the gear form many fixed sealed working chambers, which can only be used as a quantitative pump. The gear adopts the new technology of the international advanced level in the 1990s-double arcsine curve tooth profile arc. Compared with involute gears, its most prominent advantage is that there is no relative sliding on the tooth profile surface during the gear meshing process, so the tooth surface has no wear, running balance, no liquid trapping, low noise, long life, and high eficiência. The pump gets rid of the shackles of traditional design, making the gear pump enter a new field in design, production, and use.
Pump classification
As far as the core component gears are concerned, they are mainly composed of common normal gear pumps and arc gear pumps. Common normal gear pumps are more durable than circular arc gear pumps when transporting impurity media, and circular arc gear pumps have a special structure, transport clean media, low noise, and long life. Each has its own advantages.
Packing & Delivery
Before packaging, we generally evaluate the fragility of the goods and the value of the goods, and then select the appropriate inner packaging materials. Secondly, we consider that various situations may occur during transportation, and we have requirements for the compression, shock and water resistance of the outer packaging of the goods.
About the shipping method, Cabin usually use sea shipping methods, and the port can be specified by the customers.
