W-type single-stage cantilever type vortex pump structure: Open vortex pump usually adopts closed flow channel, the suction inlet and discharge port are opened at the root of the blade, which is not connected with the flow channel. In addition to the closed flow channel structure, the open vortex pump There is also a structure with a centripetal open runner. Both structures have self-priming capability.

Four characteristics of W-type single-stage cantilever vortex pump
(1) W-type single-stage cantilever vortex pump with closed flow channel or radial open flow channel with self-priming capacity can be used to transport gas-containing liquids.
The self-priming process of the W-type single-stage cantilever vortex pump is similar to that of the water ring vacuum pump in terms of suction, compression, and exhaust. When the pump is started, the liquid in the blade groove of the suction inlet is thrown into the groove of the flow path blade to form a vacuum. The gas is sucked from the suction inlet; as the rotary fluid pressure of the impeller becomes larger, the gas density is compressed at the root of the blade, and the volume is continuously reduced; the discharge port opens at the end of the flow channel and near the root of the blade, and when the liquid reaches the end of the flow channel, it will Rapidly flows into the vane groove in the radial direction, and the gas is squeezed out of the discharge port and is left in the vane groove as the impeller rotates back to the inlet; this cycle achieves suction and exhaust.
(2) W-type single-stage cantilever vortex pump has better cavitation performance than closed vortex pump
The W-type single-stage cantilever vortex pump suction inlet is opened on the side of the root of the blade groove, and the liquid flows laterally into the root of the groove of the blade. Then, under the effect of centrifugal force, the liquid flow is thrown into the flow channel with less uniform impact loss.
(3)W type single-stage cantilever vortex pump has low efficiency, generally 20%~35%.
Among them, the stainless steel vortex pump adopting a closed flow passage has a large impact loss from the flow passage to the discharge port at the discharge port side, and the efficiency is generally only 20% to 27%. The use of a centripetal open flow passage can improve the liquid flow. The efficiency of flow at the outlet side is increased to 27%~35%.
(4) W type single-stage cantilever vortex pump is generally single-stage or multi-stage.
Vortex pumps are often used to transport volatile media (eg, gasoline, alcohol, etc.), and have small flow rates and high lift requirements, but do not require cavitation performance or require reliable operation and self-priming (eg, mobile fire pumps). Etc., but not suitable for conveying media with a viscosity greater than 115 mPas (otherwise the pump head and efficiency will drop significantly) and media containing solid particles.

pvc pipe sizes chard id od inner diameter outer diameterAs mentioned in a previous blog post about PVC pipe outer diameter, PVC pipe and fittings use a nominal system for standard sizing. This is so all parts with the same size in their name will be compatible with each other. All 1" fittings will fit on 1" pipe, for example. That seems pretty straightforward, right? Well here's the confusing part: the outer diameter (OD) of PVC pipe is greater than the size in its name. That means that 1" PVC pipe will have an OD that is greater than 1", and a 1" PVC fitting will have an even larger OD than the pipe.
The most important thing when working with PVC pipe and fittings is the nominal size. A 1" fitting will fit on a 1" pipe, regardless of whether either one is schedule 40 or 80. So, while a 1" socket fitting has an opening wider than 1" across, it will fit on a 1" pipe because the OD of that pipe is also greater than 1".
