Steam sandwich pot use precautions:

1, the use of steam pressure, shall not exceed the fixed working pressure for a long time2, the steam inlet valve should be slowly opened until the pressure is required, the stop valve at the condensate outlet, 

if equipped with a trap, should always open the valve; If there is no trap, first open the valve until there is steam overflow and then close the valve, 

and keep the opening degree until there is a small amount of water vapor overflow.

3, the safety valve can be adjusted according to the pressure of the user's own steam.

4, steam pot in the process of use, should often pay attention to the change of steam pressure, with the inlet valve timely adjustment.

5. After stopping the air intake, the straight mouth cock at the bottom of the pot should be opened and the remaining water should be put out.

6, tilting and stirring steam sandwich pot, each shift before use, should be refueled in each rotating part; Stir type steam sandwich pot decent parts, 

it is recommended to use cooked vegetable oil; 30#- 40# mechanical oil is used everywhere else

Steam sandwich boiler maintenance:

1, steam inlet pipe and outlet pipe joint leakage, select tight nut does not solve the problem, should add or replace the filler.

2, pressure gauge and safety valve should be regularly checked, if there is a fault in time replacement and repair.

3. After 50 hours of use, the reducer should be removed to discharge the lubricating oil, wash with kerosene or diesel, add 30#- 40# clean oil, after 150 hours of use, the second oil change, depending on the specific situation, every use to 1000 hours or so.

4, anti-rust oil peeling, should be painted in time, paint the outer pot, it is recommended to use X55-3 aluminum powder vinyl water resistant paint.

5, after 5 years of use of this pot, it is recommended to carry out safety water pressure test, and the interval time of water pressure test in the future

 will be carried out according to the requirements of technical departments around the country.The pressure P water of the hydraulic test is determined according to the following conditions:

When the rated working pressure P <0.6MPa,P water =0.15MPa;

When the rated working pressure P =0.6-0.8MPa,

P water =P amount +0.3MPa

6. The outer pan body of the pot is made of 4.0~ 5.5mm thick steel plate, steel number A3. When the outer pan is thinned to less than 2mm after years of rust,

it should be stopped.

7, the pot of stainless steel welding and stainless steel other steel joints welding, 

should use stainless steel welding rod Olympic 102, Olympic 107, Olympic 132, Olympic 137, should not use other brands.
