Knowledge of the use of laboratory small high and low temperature cycle machine

With the continuous development of economy, the application of laboratory small high and low temperature cycle integrated machine is also more and more extensive
.

In order to prolong its life, we need to understand some of its usage and maintenance knowledge
.


1.
The flow of material and the power of the motor speed may cause resonance at a certain point.
Please change the speed of the motor to avoid resonance
.

After connecting the stirring rod of the reaction kettle and installing it, rotate it by hand to pay attention to whether the concentricity is good.
If the concentricity is not good, loosen the heavy clamp, turn on the power after the clamp is correct, and adjust gradually from slow to fast
.

2.
Check whether the power supply voltage is consistent with the specifications provided on the nameplate of the machine, plug in the power plug, and turn on the power switch to select the appropriate speed
.

3.
It is not suitable for high-speed no-load operation.
The life of the electrical box is greatly affected by the surrounding temperature.
Please keep the speed regulation and the motor dry
.

　　4.
Before installation, use, maintenance, and inspection, be sure to read all the contents of this manual carefully and use it correctly
.

　　5.
Within 5 minutes of cutting off the power supply, there may still be electric shock due to the discharge of the inverter or capacitor
.

Install the machine first, then wire it by a professional electrician, and turn it on
.

The ground terminal must be grounded
.

　　6.
Install the machine first, then wire it by a professional electrician, and energize it
.

When working, pay attention to the impact damage to the equipment box by hard objects (watches, rings, belt buckles, etc.
) on the body
.

　　7.
Pay attention to the damage caused by high temperature to the human body.
Our company recommends using heat transfer oil as a solvent with little damage to the human body
.

Special attention should be paid to the high temperature cycle, the circulating pump should be turned on first, and the temperature should be raised slowly under the condition that the thermally conductive solvent is circulated
.

8.
When discharging, it is possible to accumulate residues on the PTFE piston of the valve, and the air tightness will be affected when it is used again.
It must be cleaned after each discharge and used again
