How to make a water pump made of PVC pipes
The system of irrigation and water supply in the suburban areas is vital. Without good irrigation and irrigation of crops, even on fertile land, it is unlikely that something will grow. And the water pump is the main element of such a system. It automates the movement of water, converting mechanical energy into energy of the fluid flow, designed to move it. Many use such machines in the country, and without them no longer represent success in their business. But what about those who have not used such devices, and are just wondering which of them to use? Perhaps you will need an axial propeller pump of a vertical type. This device is extremely simple, and it can be done by even a novice, who understands nothing in technology. But the benefits of it can be huge, because it is able to pump quite a lot of water from one place to another. Suppose you have a storage tank with rainwater in the area in which water collects on the bottom side after the rains. Carrying her buckets is tiresome, and moving and not at all possible.This is where a homemade product comes in, which we will look at today - a simple and efficient axial pump assembled from virtually nothing. And this is not a typo, because the cost of its components is less than $ 10. Can not it be? We offer to make sure of this with us.Doing the pump axis from a bicycleknitting needles. The metal is hard, corrosion-resistant. On the other end, the spoke has a bend for attaching to the bicycle disk. We bite off this bend with pliers, and push a small adapter onto it for the motor shaft. We fix it on the spoke with solder.We put the impeller on the pump axis, departing from the end of 3-4 cm. Fix the impeller, soldering on both sides with a soldering iron. Blades give shape to the propeller.We put the pump axis on the engine shaft. The engine itself is fastened through the gasket to the PVC tee on hot glue. At the bottom of the suction pipe we place the distributor out of a piece of aluminum wire to eliminate the twisting of the flow.Solder the copper contacts to the engine. They can be further insulated with heat shrink. Connect the pump to the battery, and place the suction pipe in a container with water.Now your site will not be left without irrigation and irrigation, because you have an excellent and powerful enough device for pumping water.Everyone can do it, and the cost of components will not burden the budget even for retirees or novice lovers of dacha business!
The principle of the axial pumpThe plastic tube is the pump casing. Inside it is an axis with one impeller, which works as a guide for the axial flow of the pumped liquid. The blades of the propeller create a vortex flow of the type of fan, changing the pressure inside the pipe. Water from the lower part is drawn into the tube, and moves under pressure into a free lateral outlet. Such rigidly single-stage pumps do not have a dry suction and have a small allowable vacuum suction height. Pump operation is based on a pressure change between two different density media — water and air. To ensure cavitation-free operation, these pumps are placed below the free level of the pumped liquid, i.e.the impeller of the pump must be constantly in the water.
We manufacture a water pumpRequired materials: Tools:
- Soldering Iron;
- Plumbing Soldering Iron or Iron;
- Hot Melt Glue Gun;
- Marker, pliers and paint knife.
Making a bodyFor the pump body, we will need a PVC pipe and tee. We cut two lengths of 25 and 6 cm from the pipe. We connect these branch pipes with a tee as shown in the photo.
Prepare an axis with an impellerMark the metal plate with a width of about 1 cm. Make a hole for the shaft or axis. We cut the plate along the contour of the inner circumference of the pipe.
Connect the engine and collect the pumpThe engine attached to the upper tee outlet must be isolated from water. To do this, we cut out from plexiglass a small gasket to fit the outer circumference of the PVC pipe. We fix this element on the hot glue to the engine, leaving only the zone of its shaft open.
