Factory wholesale TU-1F93 thermal wax actuator for thermostatic automatic water drain valve Export to Moscow 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.

OK, we’ve got an AC just barely cool in here. Kind of low on freon. Ompressor’s pretty hot to the touch. Unit’s still running.
It’s going to be charging up through the low side. You’ve got a tiny leak at the evaporator. So we’re going to be using a micro additive. Got our gauges calibrated.
We’ve got a couple of things we can make better. Got our new fan capacitor. We could secure that up. Make that better.
Make sure all our gauges are turned off here. And I’ll remove the cap on the low side. It’s blazing hot today. Probably 109 degrees out here today.
Just going to try to get this going and get off the roof. It’s pretty humid today too, so not the easiest day to be up here. Looks like the Schrader valve cap needs to come out with the cap. It’s kind of stuck on the end there.
Make sure we recover that. There’s our o-ring. Put that back in the cap for later use.
Now we’re going to hook up our quick connect fitting. This is a low loss fitting. Prevent frostbite. Want to wear gloves. Wear safety glasses.
Now we can check our reading up top. See what our pressures are. So we’re showing at about 30, which means we’re just a little bit low. And purge the line.
Make sure all the valves are tight here. Pick up our refrigerant can at the end. Got my can of refrigerant up here. Going to set it up top and run the middle line.
Charging port hooks up to the tank of refrigerant. OK. Open the line.
And back down here, we’re going to go ahead and purge. Purge the line. Purge both sides. Now we’re ready to charge.
Now, because the compressor is really hot, I’m going to dump some cold water. All I have today is cold water. And I actually prefer to use a little bit of ice to cool it down, speed up the charge. But I’ll be using the cold water instead.
So this has been in the fridge for a while. That will help speed the charge up. Going to monitor the line. It’s already starting to feel a bit colder. I’m monitoring it with my wrist here.
What we wanted is for this line here that goes down to the evaporator. And the temperature at the evaporator will start to backtrack up this line to the compressor. This is the suction line. It’s why we’re sucking in the refrigerant there from our tank up top here.
But what I have is capillary tube system at my evaporator coil. And the capillary tube system is a metering device that only lets so much refrigerant through at a time. Now the deal is, the temperature of the evaporator coil needs to be about 40 degrees, which is above freezing. You know, water freezes at 32 degrees. So just keeping that coil temperature up above that amount will mean that our coil is not going to freeze up, and we’re going to be removing heat from inside the unit.
Now as the evaporator coil reaches its 40 degree temperature, it’ll back up into this line. So this low side line is nice and chilly. And that’s going to tell us that our evaporator is that cold also. So that’s how we can kind of monitor and charge this unit up, charge it to where we need it to be.
Again, with the capillary tube system, it’s pretty forgiving. You’d have to really try to overcharge it. Obviously, you don’t want to overcharge it. You want to avoid overcharging.
But again, it meters the refrigerant at a fixed orifice rate. It’s a fixed size. Only lets so much refrigerant through at a time.
Automatic Climate Controls (if so equipped)
This is the climate control panel for adjusting air flow, fan speed, temperature, air conditioning, defrosting or defogging, and air intake.
The Auto mode may be used all year round. For automatic cooling or dehumidified heating, turn both the FAN SPEED CONTROL dial and the AIR FLOW CONTROL dial to AUTO. It will automatically regulate and maintain fan speed, air flow and temperature in the cabin.
This FAN SPEED CONTROL dial regulates fan speed at various settings. Turn to the left for slower speed, to the right for higher speed. To turn the system OFF, turn the dial all the way to the left.
Press the AC button to turn the air conditioning ON. An indicator light will illuminate. Press again to turn OFF. This is the TEMPERATURE CONTROL dial in the center. Turn it to the left for cooler, or to the right for warmer air.
This is the AIR FLOW CONTROL dial, which allows you to select air flow outlets. Refer to the pictograms for the various air flow combinations:
- Air will flow from center and side vents, From center, side and foot vents, Mainly from foot vents, and from the defroster and foot vents
Note: in hot or humid conditions, a visible mist may be seen coming from the vents. This does not indicate a malfunction.
Press THIS button to change the air circulation mode to air recirculation, outside air circulation or automatic control. When the air recirculation mode is selected, this indicator light will illuminate. The flowing air is recirculated inside the vehicle. This helps AC efficiency and helps block outside odors from entering the cabin. When the outside air circulation mode is selected, this indicator light will illuminate and fresh air will be drawn into the vehicle. If the circulation mode is set to automatic control, both indicator lights will turn OFF and the air intake will be controlled automatically.
To defrost or defog front and side windows, turn the AIR FLOW CONTROL dial to the DEFROST setting. Next, turn the TEMPERATURE CONTROL dial left or right to set the desired temperature. To set the defroster on high, turn the FAN SPEED dial all the way to the right. For windshield deicing, your temperature selector should be turned to maximum heat.
To defrost or defog the rear window and, if so equipped, the outside mirrors, push the REAR WINDOW DEFROSTER switch. The indicator light will illuminate. After defrosting, push to turn OFF. If not turned OFF manually, this feature will automatically deactivate in 15 minutes.
