The HTHP Dual Flow Dyeing Machine should carefully check the sieve filter and clean it before starting it; check whether the thermometers, pressure gauges and other instruments are in good condition; check whether the motor, electrical appliance and lighting system are in good condition; check whether the various valves are in good condition, especially It is the safety valve that must work properly.
Then according to the different types of cloth, the nozzle needs to be replaced when it needs to be replaced; before the water is introduced, the cooling water valve of the mechanical seal of the main pump is opened to prevent overheating and damage. Before entering the cloth, check whether the cylinder mouth will cause the hook thread, and pay attention to the appropriate impulse. Dissolve and add dyeing chemicals and additives, and pay attention to avoid splashing of the solution.
When the high temperature and high pressure double liquid dyeing machine is running, the operator shall not leave the post or sleep. The pressure in the cylinder and the pressure of the joint should be checked at any time. The steam valve of the safety valve should be closed immediately or the steam valve should be closed immediately; If it is suspended, measures should be taken immediately, but the cylinder head cannot be opened. If the thrust is still being lifted, the cylinder head must be lowered before the temperature can be lowered.
After the high temperature and high pressure double liquid dyeing machine is dyed, the steam valve is closed first, and then the cooling water is turned on to cool down. To open the cylinder head, it is necessary to display no pressure on the pressure gauge. The temperature is below 80C. The machine can be opened under the condition that the machine stops running and the steam source is cut off to avoid burns. After the sampling is accurate, the sewage can be drained, and the water is cleaned before being discharged.
