The hthp overflow jet dyeing machine uses a square walking tube to break the traditional circular structure. Therefore, the introduction of this structure solves the problem of the rotation of the fabric during the dyeing process, thereby ensuring the levelness of the fabric, eliminating the chromatic aberration and color plaque caused by the spin-up of the fabric, and making the dyeing effect more ideal. The overflow jet dyeing machine can dye most of the knitted fabrics, and the quality of the dyed products is good, and the cost is reasonable. Therefore, the dyeing equipment of the knitted fabric printing and dyeing enterprises has a high occupation rate.

Then, what is the reason for using the overflow jet dyeing machine to slow down or not warm up?

（1）The reasons for slow or no warming are:

1. Insufficient steam

2. The steam trap is blocked or the displacement is insufficient.

3. Steam control valve is damaged

4, the temperature controller is faulty or improperly set

5, Condensate recovery pipe back pressure is too large

6, The tank body leaks or the exhaust valve is not closed.

Approach:

l, check the steam pressure supplied

2, clean or replace the steam trap

3. Check if the air pressure is sufficient.

4. Replace or reset steps

5, replace the steamer specifications or heavy piping

6, check the leak and close

（2）The reasons for slow cooling are:

1. Insufficient cooling water

2, the cooling water temperature is too high

3. The cooling water control valve is damaged.

4, the cooling water backwater pipe back pressure is too large.

Approach:

l, check the cooling water pressure

2, the water temperature is kept below 25 °C

3. Overhaul the control valve and check the air pressure

4, cooling water pressure, if necessary, re-pipe.
