2400t veneer hot press in normal operation automatically to fall and then automatically rise what are the reasons

The hot press is one of the most important equipments in the production of artificial board. The production capacity of the hot press determines the output of the wood-based panel production line, and the technical level of the hot press also determines the quality of the wood-based panel products to a large extent. The development of wood-based panel production is closely related to the progress of hot press technology. The development of wood-based panel industry puts forward higher requirements for hot presses, while the emergence of more advanced level of hot presses has greatly promoted the development of wood-based panel industry.

According to your description: your veneer heat press has the phenomenon of oil return! Below I put the hot press common problems related to oil return and pressure related to give you a list! You understand!

The veneer heat press to play high-pressure high-pressure oil return is generally caused by the following reasons:

1, the failure of the master valve, resulting in automatic oil return, high-pressure check valve or pipeline check valve is not closed tight, resulting in oil leakage, there is also a reason for the solenoid valve is likely to be out of order!

2, high-pressure pump failure, the pressure does not go

3, high-pressure safety valve spring pressure is low, the automatic return

4, pipeline oil leakage, pipeline rupture or joints disconnect

Solution:

1, check the general valve oil return, overhaul, check the valves for overhaul. There are also solenoid valves to check!

2, check the piston and valve of the high-pressure pump

3, check the high-pressure safety valve to adjust the pressure

4, check the pipeline, overhaul

Hot presses can not keep the pressure of the reasons are caused by the following reasons:

1, the high-pressure pump malfunction, the pressure does not go

2, oil leakage of the cylinder seals

3

Solution:

1, adjust or replace the sealing ring, check the surface corrosion of the piston and whether the pressure ring is pressed tightly

2, check the upper end of the piston (hollow) whether there is leakage out of the oil, check the outside of the cylinder whether there is leakage, repair or replacement.

The reason why the hot press pressure is slow is caused by the following reasons:

1, there is air in the cylinder

2, low pressure or high pressure pump inhalation of air

3, insufficient accumulator pressure or insufficient storage of air

Solution:

1, open the cylinder bleeder screw, bleed the air

2, check the oil pump suction, to correct the situation. Check the oil pump suction situation, and correct it

3, check the pressure of the pressure accumulator and the amount of air storage

Several cylinders piston rise inconsistently due to the following circumstances:

1, rising piston sealing ring is too tight

2, the sealing ring is not the right size

Solution:

1, loosen the piston sealing ring pressure ring

Solution:

1, the piston sealing ring pressure ring

Solution:

1, loosen the piston Loosen the piston's sealing ring

2, replace the wrong size sealing ring

The reason why the temperature of the hot platen does not go up is caused by the following situations:

1, water buildup in the hot platen

2, the hot platen steam passages are blocked

Resolution:

1, check the steam trap, discharge condensate

2, Check the temperature does not go on the hot platen

I hope the above answer can help you solve the problem, such as there is still a problem about the hot press, please call: Linyi Jinzuo wood machinery, Jinzuo Wood Machinery's technical department of engineers will give you a satisfactory answer! Help you solve the problem!
