factory wholesale good quality TU-020 thermostatic cartridge wax sensor for sanitary ware for South Africa Factory 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.

“ECHO” machine is a multi color 3D printer has been designed using of the addictive manufacturing techniques regarding the rapid prototyping process. This is technique known as (Fused Deposition Modeling – FDM). First, and like all 3D printer machines, the CAD file of the part which is wanted to be printed to a 3D object is exported with (STL) extension. This extension allows the 3D printer program to view the part as accumulative geometric surfaces rather like the surfaces resulted in (Finite Element Analysis – FEA). Using the 3D printer program, the part can be converted to many tiny slices and then these slices are sent in successive method to the 3D printer machine so the part will be built slice over slice until getting the full 3D built part at the process end, as a result this built part and the modeled part in the CAD program will be alike. This technique, for the purpose of building implement, is count on melting a thermal polymer which pours after positional melting form the actuator head nozzle. The actuator head traces the cross section of the processed slice and builds according to it until the full completely of the slice section. The procedure is repeated many times to complete the part building. This technique uses another thermal polymer as a supporting material to fill all part gaps and to support the built part body is case of balance adjusting during the building process. After the building end, the support material is got rid of and we will get a part or a product built from just the building material.
In this printer, the thermal polymer (Acrylonitrile butadiene styrene – ABS) is used, this plastic polymer melts in a Celsius degree between (180 – 220) degrees, and it’s provided in the markets as a filaments coiled around a roll, the used filament diameter is (1.75mm), ABS filaments substance has a color vary (in this machine the blue, red, yellow ones are used as a building material).
Regarding the supporting material, the used thermal polymer is (Polyvinyl acetate – PVA), this plastic polymer melts in a Celsius degree between (180 – 220) degrees, and it’s provided in the markets as a filaments coiled around a roll, the used filament diameter is (1.75mm) and it’s often found in white color (the roll located at the right side of the machine). The important specification for this material is the ability to dissolving into the water. Consequently, after building the part, it’s enough to submerge it into the water and so the supporting material will dissolve into the water and the building material will remain.
Both of building and supporting material are provided to the actuator head nozzle by means of a feeding mechanism which consists of a feeder for the purpose of pulling in the plastic filament from the roll and then guiding it into a canal ended with the melting chamber which is in touch with a ceramic heater (40 watt). And thus, the material is melted and poured out through the nozzle which has an orifice with diameter of (0.5mm). The feeding mechanism includes a cooler made from aluminium substance to prevent the heat from transferring toward the top. The number of actuator heads and feeders is four (three actuator heads for building and the remained one is for supporting). The heat exchange can be done for the four coolers by two fans behind the actuator heads.
Regarding the Mechanical Design Side, this machine has three axes (X,Y,Z). it depends for moving the actuator head along the (Y) axes, which it represents the machine gantry, on a motion method consists of a stepper motor and high accuracy synchronous pulleys and belt. The motion of the axis (Y) vertically along the axis (Z) is achieved by means of a pair of ball screws located at the two sides of the machine. According to the (X) axis, it’s the motion of the work table to front or back using stepper motor and synchronous pulleys and belt. In all axes, guiding mechanisms are used, they consist of rails with (V) shape and over them wheels with (V) shaped grooves are moving on them. In the (X) axis, in addition of the previous guiding mechanism there is a cylinder guider “Ball Spline” which is used to add more support for the table.
The work volume or field for this machine is (40cm×40cm×40cm).
Regarding the Dynamic Analysis, the inertia forces and torques were studied, and so the maximum and minimum velocity required to move the actuator head. Consequently, stepper motors were chosen, the number of them is like the number of the axes, these motors rotate (0.9 degree) by each pulse they get, these motors characterized with a high accuracy, the value of rotation will surely taken in consideration to determine the printer accuracy, the load torque for each motor is (4.4 Kg.cm). The building speed according to the (Y) axis is (150 mm/s) in maximum.
An animation of the hydraulic rotary actuator shown in the video posted by AvE. This is not a hydraulic motor as the output shaft only rotates 360 degrees in total, but the output torque is substantially higher.

The outer housing (yellow) is fixed. Hydraulic pressure drives the piston (green) up and down along the axis of the housing. The output shaft (red) is free to rotate but constrained axially.
The piston is engaged with the housing via a left-handed thread. This causes the piston to rotate at it travels up and down.
The piston is also engaged to the output shaft via a right-handed thread. As the piston moves down, the output shaft is forced to rotate. The rotation of the piston and output shaft are in the same direction, causing the total output rotation to be the sum of:
(piston displacement * piston-housing thread lead) + (piston displacement * piston-shaft lead)
In this model, the piston-housing and piston-shaft leads are the same, though this is not a physical requirement. The result is the rotation of the shaft is double the rotation of the piston. Different leads on the engaging threads can result in more or less output rotation at the expense of torque and internal friction.
