Chinese wholesale TU-1C91 thermal wax actuator for industrial adjustable temperature switch control for Angola Importers Detail:
1. Operation Principle
The Thermostatic Wax that has been sealed in shell body induces expansion by a given temperature, and inner rubber seal part drives its handspike to move under expansion pressure to realize a transition from thermal energy into mechanical energy. The Thermostatic Wax brings an upward movement to its handspike, and automatic control of various function are realized by use of upward movement of handspike. The return of handspike is accomplished by negative load in a given returned temperature.
2. Characteristic
(1)Small body size, occupied limited space, and its size and structure may be designed in according to the location where needs to work.
(2)Temperature control is reliable and nicety
(3)No shaking and tranquilization in working condition.
(4)The element doesn’t need special maintenance.
(5)Working life is long.
3.Main Technical Parameters
(1)Handspike’s height may be confirmed by drawing and technical parameters
(2)Handspike movement is relatives to the temperature range of the element, and the effective distance range is from 1.5mm to 20 mm.
(3)Temperature control range of thermal wax actuator is between –20 ~ 230℃.
(4)Lag phenomenon is generally 1 ~ 2℃. Friction of each component part and lag of the component part temperature cause a lag phenomenon. Because there is a difference between up and down curve of traveling distance.
(5)Loading force of thermal wax actuator is difference, it depends on its’ shell size.

How To Make Your Own Musical Greeting Cards
3 Easy Steps!
Courtesy of www.SoundExpressionGreetings.com:
STEP 1
You will want to start with a high quality recordable greeting card sound module where you can record your own 10 or 20 second message. For wholesale pricing on 20 or more: https://www.soundexpressiongreetings.com/musical-greetings/recordable-sound-modules.html
If you only want 1 or 2 modules, you can purchase through Amazon.com:
https://www.amazon.com/gp/product/B001U33PC6
There is an easy template to follow if you plan to print a 5 x 7 sound card:

Regardless of the finished size of your card, you will want to start with a longer sheet of paper with 2 folds. If you are custom printing, you will want to print before folding (scoring) your paper.
STEP 2
Record your 10 or 20 second song or voice message onto the greeting card sound module by following the instructions on our webpage below or on our video:
https://www.soundexpressiongreetings.com/musical-greetings/recordable-sound-modules.html
You may have to experiment with the distance of recording into the
Micro-speaker to achieve the best results.
You may re-record as often as desired.
STEP 3
Peel off wax paper backing of your module and line up side notches of the white pull tab to the inside left fold of the card.
(As shown on our webpage instructions and/or video).
Test your sound by opening your card to play back message.
(Your message should play up to 300 times each time your card is opened.)
Fold down the 3rd panel covering the sound module and use double stick tape or glue stick to secure paper panel into place.
Congratulations! You have learned how to make your own musical greeting card.
This is a recent version of a PVC ram pump that I first developed in about 1991. It is very low profile to avoid damage during high water, and can run under water 24/7 since the air is separated from the water in the air chamber – no need for a snifter valve. This pump can raise water to a height at least 15 times the fall (drive head). Of course, the output tapers off the higher you pump. All of the components are very simple and inexpensive but have proven themselves over millions of cycles. This particular installation is to feed two slow sand filters under test in the house in the background. (See my other Ram Pump video for the updated version of this pump)
