Working principle and performance characteristics of constant temperature oil tank

The working principle and performance characteristics of the constant temperature oil tank The flow and temperature control system of the oil in the tank body of the constant temperature oil tank is driven by the paddle driven by the motor.
The oil is heated by the heater in the mixing area and flows from top to bottom.
The flow is fully mixed, and the temperature of the oil flow reaches a uniform and consistent temperature, and then the flow is directed upwards into the working area.
In the working area, the oil flow requires a suitable flow rate and good thermal insulation to ensure that its temperature in the working area is uniform and stable; after that The oil flow enters the mixing zone again, and the combined flow is circulated in turn

1.
The working principle of the temperature controller The temperature-sensing element of the temperature controller is a platinum thermal resistance thermometer placed in the fluid to detect temperature signals, so that the temperature control device can send out control signals in a PID adjustment mode according to the change of the bath temperature, and control bidirectionally controllable The size of the silicon conduction angle, adjust the heating power of the heater, so that the bath temperature is stable at the set temperature
.

 2.
Oil supply circulation system: (some oil tanks have no oil storage tank, which needs to be done manually) This system is not activated when the oil tank is working normally, and only works when oil filling is required
.

The specific structure is as follows: an oil storage tank is provided at the bottom of the oil tank, and the oil in the oil storage tank is pumped into the oil tank through the oil pipe through the oil pump and the reversing valve; if the oil in the oil storage tank needs to be cleaned, the reversing valve and oil change The drain valve is drawn away from the oil storage tank.
When the oil tank heats up, the overflowing oil will be directly discharged into the oil storage tank through the overflow pipe.
If the tank temperature needs to drop rapidly, the oil drain valve can be opened, and some high-temperature oil in the tank can be put into the oil storage tank.
After that, the oil pump is used to pump the cold oil into the tank through the oil delivery pipe, thus, the oil supply circulation system makes the working environment clean, and the operator's operation is relatively simple and efficient
.

3.
Temperature control system The oil thermostatic bath is required to establish a uniform and stable thermal environment within its working range and at any set temperature.
Therefore, the equipped temperature control system is very important
.

In addition, the structure of the thermostatic tank, the thermal inertia of the system, the uniform heating condition of the medium, the mixing and good flow state, the advantages and disadvantages of the thermal insulation of the device, and the stability of the operation of the whole machine, all directly affect the temperature control quality
.

At present, the equipment used for the analysis of the influencing factors of the temperature field of the constant temperature bath in Chapter 3 adopts the digital display temperature controller and the device to achieve high-quality temperature control.
The uniformity can reach 0.
