Due to the need to meet the fun of a child, the family more than a few tail fish (ball, Mickey), and these poor fish in the home a day or two later namely forgotten. In view of the significance and value of life by example the need for long-term education, the responsibility of feeding fish and serve it fell on me.
Changing the water every day good this trouble, do not feel dirty and I'm sorry for what those little life, so a little small for that fish tank water treatment system installation becomes a very necessary thing.
I am not a fan of this, those who do nitrifying bacteria, biochemical, cotton, glass ring, filter barrel. . . . . . Think like a lot of trouble, and these fish is estimated that it would not open, so I plan to be a simple treatment devices, too much shit to clean up even if the. This need to use pumps to suck it up and going to the toilet, and then do some simple filtering. Although the micro-pump on Taobao some, it looks like ten twenty, but this is not a hands-on fun,
mlb jerseys, they still make their own good, the children enjoyed the fun of watching the fish, I enjoy the hands-on fun Ha ha.
After nearly a month time, the production of fragmented,
cheap nba jerseys, small changes in the pump has gone through three generations,
nba jerseys, has now been successfully installed and used, but the production process where the fun is in the record a little bit here.
Centrifugal pump using the principle of the water by turning \Generation and second generation of pumps is the computer's cooling fan, the benefits are easy to find materials, but also easy to handle, the downside is that high energy consumption (more added later)
Cooling fan (disassembled): removed the permanent magnet, circuit,
lebron james jerseys, simple processing
shell
Finished (generation): As part of the central axis fan page bigger, so the intake is not centered, outlets treated as tangential as possible, the original expected to save the small pump on the cylinder outside the cylinder so a little bit of space, who knows the shaft where there are water leaks out. In addition, the motor is a motor old toys removed, 3V drive.
Axis improvement (II): Keep the original bearing part of the fan,
dwyane wade jerseys, in addition to lower friction, a more stable rotation axis, but also can reduce leakage opportunities (skilled ideal, on the cylinder is not leaking at the wrong photo, but flow lower)
Summary of a second-generation product, the cooling fan fan page is tilted about 45, while in turn have led some of the water power loss in the void direction (pointing to the direction of the motor), so making out the effect is not very good, the water head is low. If you use the 4.8V or 9V adapter driver, the pump will turn for a little heat stop. The practical application is not ideal. Therefore, the third generation also came into being.
Fan page improvements (three generations): the core using a tape, of course, the core of the original appearance of the tape is not the case, this is the finished product after processing is complete. Pure lateral drainage, improve work efficiency. Pump housing: a small plastic bottle, center cut.
Semi-finished products: fan page is partly surrounded YY badminton hand the middle of the plastic adhesive circle,
barcelona jersey, the right size to trap the plastic bottle, the side openings make water pipes. Outlet pipe using a ball point pen in the pen.
beta product: door position switch motor to drive the drive motor, 1V can be driven, but that just kept using the 12V voltage is not wrong turn, fever situation in an acceptable range. Pump on the bottom half of plastic bottles, as the inlet, large bottles of body under the small, easy to pump water evenly distributed fan page. The upper part of the intention to seal the bottom with a plastic handle, in order to do submersible pump, but then I did not much need to pump in a fish bowl wall hanging to ensure that even if the motor does not touch water. Plastic bottle now so I opened the hole used for installing a filter sponge, is responsible for filtering small fish poo. After testing, the transformer can be used to meet the daily needs 1.5V, if a 9V, it is estimated that all the water and flew away.
Now this little pump has to work a normal day, I work from home work before going to sleep at night, meritorious, worthy of praise. Supplemented according to another day of work.
