Pool Drain Pump Without Electricity

If we have a fish pond, of course, sometimes we need to clean the water because of the large amount of sediment in the pond.

In this cleaning process, we only need to suck up only the bottom of the pool without having to throw away all the water, because to fill the pool completely requires a large amount of water.

If our pool is positioned higher than the disposal site, of course it's easier to just drain the bottom part by sucking it using a hose and the end of the hose is directed to the bottom of the pool.

The problem is that we often have to suck it up using our mouths and that's really disgusting because the pool water is dirty and sometimes smelly, especially since it used to suck up the bottom. So, in the following video, we make a tool so you don't have to suck it up using your mouth, we make drain pump without electricity:

Fixing a Stuck Aquarium Pump

The aquarium pump sometimes gets stuck and stops and doesn't want to run when the power goes out, this can be caused because the pump is too dirty so the propeller doesn't want to spin.

Another problem will arise if when you disassemble the propeller and magnet parts, there are parts that are missing or fall into the water so that your pump cannot run perfectly anymore. Usually it is the part connected to the magnetic shaft that falls out when the cover is opened.

Here is a video where we can make our own parts to deal with an aquarium pump that tends to jam.

Water Pump Without Energy

 A water pump without electricity is really a hoax A lot of content on YouTube shows that they can make a simple tool that can pump water without electricity.

 Actually pumping water does not have to use electrical energy but can use solar energy or the energy of moving water. For example, the Hydram Pump does not require electrical energy but uses the energy of moving water which is converted into pressure energy. So that it can pump water to a higher level, and this is not a hoax.

As in the video below, I made a hydram pump on a small scale, namely a 1/2 inch pipe, of course it can't push too high, but the point is it can pump to a higher level.

 

 Unlike the hoax content about a water pump without electricity, the video shows that it can pump water from a deeper river to a higher road, obviously this is impossible. Therefore I also make videos about things that prove that the content is not true, like in the video below:

CONTROL VALVES

Fig. 1 Control Valve

What is Control Valve?

Control valve usually use in industrial pipe line. Using this control valve people or operator can control to open or closed this valve from control room. Sometime the location of control valve itself is far from the control room. Other part are similar with normal valve but on the stem to open valve is connected to control device.

A control valve consists of a valve, an actuator, and possibly one or more valve-control devices. The valves discussed in this section are applicable to throttling control (i.e., where flow through the valve is regulated to any desired amount between maximum and minimum limits). Other valves such as check, isolation, and relief valves are addressed in the next subsection. As defined, control valves are automatic control devices that modify the fluid flow rate as specified by the controller.

Valves are categorized according to their design style. These styles can be grouped into type of stem motion—linear or rotary. The valve stem is the rod, shaft, or spindle that connects the actuator with the closure member (i.e., a movable part of the valve that is positioned in the flow path to modify the rate of flow). Motion of either type is known as travel. The major categories are described briefly below.

Globe Control Valve

Fig 2. Globe Control Valve

The most common linear stem-motion control valve is the globe valve. The name comes from the globular shaped cavities around the port. In general, a port is any fluid passageway, but often the reference is to the passage that is blocked off by the closure member when the valve is closed. In globe valves, the closure member is called a plug. The plug in the valve shown in Fig 1 is guided by a large-diameter port and moves within the port to provide the flow control orifice of the valve. A very popular alternate construction is a cage-guided plug as illustrated in Fig.2. In many such designs, openings in the cage provide the flow control orifices. The valve seat is the zone of contact between the moving closure member and the stationary valve body, which shuts off the flow when the valve is closed. Often the seat in the body is on a replaceable part known as a seat ring. This stationary seat can also be designed as an integral part of the cage. Plugs may also be port-guided by wings or a skirt that fits snugly into the seat-ring bore.

One distinct advantage of cage guiding is the use of balanced plugs in single-port designs. The unbalanced plug depicted in Fig. 1 is subjected to a static pressure force equal to the port area times the valve pressure differential (plus the stem area times the downstream pressure) when the valve is closed. In the balanced design (Fig. 2), note that both the top and bottom of the plug are subjected to the same downstream pressure when the valve is closed. Leakage via the plug-to-cage clearance is prevented by a plug seal. Both plug types are subjected to hydrostatic force due to internal pressure acting on the stem area and to dynamic flow forces when the valve is flowing.

The plug, cage, seat ring, and associated seals are known as the trim. A key feature of globe valves is that they allow maintenance of the trim via a removable bonnet without removing the valve body from the line. Bonnets are typically bolted on but may be threaded in smaller sizes.
