The pressure of the pressure barrel is generally no standard, as long as the water can be pressed out is normal. Under normal circumstances, the pressure of an empty bucket is 0.4-0.5 kilograms, and that of a full bucket should be 2-2.2 kilograms.
Ordinary pressure barrel is also called storage barrel, the glue or fluid into the pressure barrel, through the pressure (connected to a regulator, easy to control the size of the air pressure, and to ensure that the air pressure is constant), the glue out of the pressure, pressure to the required dispensing position.

Note
In the use of the process, to ensure that the live knot screw has been locked barrel cover, in order to be used normally, to ensure that the safety valve is qualified, can not use the safety valve has been broken, it is best to replace the safety valve on a regular basis, to ensure that the use of security. If the glue is corrosive, the use of 304 stainless steel pressure barrel, or the use of 304 inner barrel is best.
Classification
Pressure drum according to the material is divided into carbon steel and stainless steel, carbon steel material appearance by powder coating treatment is not recommended to pour the material directly into the liquid, you can use the glue drum into the barrel or stainless steel barrel storage method. Stainless steel can be directly poured into the material liquid storage.
Stainless steel pressure barrel material can be divided into 201 material, 304 material and 316 material.
201 material, 304 material and 316 material pressure barrel material selection is mainly based on the need to store the liquid components, such as strong acids and strong alkalis must be selected 316 material; Tannat water type of liquid need to be 304 material, and the dispensing industry with more epoxy resin, silicone, etc. can be used 201 material.
Stainless steel barrels are divided into: ordinary pressure barrels, piston pressure barrels, cylinder piston pressure barrels, stainless steel heated barrels, carbon steel heated barrels, head pressure barrels, the bottom of the glue pressure barrels, glue special pressure barrels.
