ডালিয়ান TEIKOKU টিনজাত পাম্পের টিআরজি মিটারের সাধারণ ত্রুটিগুলি কীভাবে সমাধান করবেন?

1

The hands of the watch gradually   increase, the pointer does not swing, and sometimes the operation is not good

The power supply voltage increases or the   bearing wear increases.

First check whether the terminal voltage   is normal, and then check the bearing wear. If it exceeds the value, replace   the bearing with a new one.

2

The needle swings irregularly, the flow   and pressure of the electric pump are unstable, the internal sound is   abnormal, and sometimes the end is heated

The circulating fluid system is abnormal,   the flow is insufficient or there is air

Check the circulating fluid pipeline and   check whether the type of electric pump meets the process requirements

3

The hands suddenly rise to the red zone,   and the swing of the hands increases and fluctuates regularly. Sometimes   restart after shutdown, the fault disappears

The expansion of the rotor cage bars   causes local breakage

Replace with a new rotor of the same   model

4

The needle suddenly rises to the red   area, the swing of the needle increases and there are regular.fluctuations   accompanied by abnormal sound inside the pump

The impeller shakes, the rotating shaft   is bent, and the mouth ring is worn

Disassemble the electric pump casing to   check and repair the damage

5

The needle is greater than 0.75, the   operation sound is not smooth, and the flow and pressure are low

ফেজ ক্রম বিপরীত

Check power phase sequence and reconnect   power

6

The needle is normal, the operation is   not smooth, the flow pressure is low or the operation is normal, and the   needle is greater than 0.75

The three-phase power supply of the   module does not match the phase sequence of the motor terminals. TRG and   thermal element circuit are reversed

Check the phase sequence of the   three-phase power supply of the module and the lead wires of the motor   terminals and connect them in the correct phase sequence

7

The needle is normal, the operation is   not smooth, the flow pressure is low or the operation is normal The needle is   greater than 0.75

The three-phase power supply of the   module does not match the phase sequence of the motor terminals. TRG and   thermal element circuit are reversed

Check the phase sequence of the   three-phase power supply of the module and the lead wires of the motor   terminals and connect them in the correct phase sequence

8

When the needle is greater than 0.5, the   current of one phase is zero

ফেজ আউট

Check the power cord and connect the   power

9

The hands of the watch are suddenly large   and small or swing, this phenomenon is temporary

The pipeline is mixed with foreign   matter, or the working fluid has crystals or precipitates

Check the working fluid and circulation   pipeline, and discharge foreign matter

10

The electric pump works normally, the   positive and reverse connection of the power cord is always greater than   0.75, and sometimes the fault disappears after stopping for one stage and   then restarting

The module or TRG meter is damaged or the   TRG system loop is grounded

Check the input and output electrical   parameters of the module, check the grounding points of the modules, circuit   boards and electrical circuits

11

হাত ইঙ্গিত বা বিপরীত না

The polarity is reversed when the module   is reassembled after inspection. The instrument is damaged and the module is   selected incorrectly

Check the selection type of the instrument   and the module, whether the module mounting hole and the polarity of the   instrument conform to

13

The main circuit terminal has zero   insulation to ground, or trips when starting the electric pump

The wiring frame is damaged, the module   is damaged, and the main winding is damaged. TRG and thermal element circuit   are reversed

Remove the module and main winding from   the wiring frame and check separately
