InactiveCN103791097AReduce wearImprove the state of friction and lubricationEngine sealsSolid particleEngineering
The invention relates to a combination fluid dynamic pressure groove mechanical seal ring structure capable of automatically discharging particles. The combination fluid dynamic pressure groove mechanical seal ring structure is characterized in that on a sealing moving ring or a static ring, a circulation outer circle arc groove and a pumping groove which are symmetrically arranged about the rotation center are sequentially arranged from the high-pressure side and the low-pressure side. The outer circle arc groove is formed in the upper portion (high-pressure side) of the end face and the pumping groove is formed in the lower portion (low-pressure side) of the end face. The arc groove and the pumping groove are communicated at the contact place so as to ensure that the particles entering the pumping groove enter the arc groove by means of the pumping effect and return to a sealing cavity through medium circulation. Meanwhile, by means of the dynamic pressure effect and the pumping effect of the arc groove and the pumping groove, the bearing capacity and the low leakage amount of a liquid film are ensured. Thus, the good sealing capacity and the automatic particle discharging capacity of the combination fluid dynamic pressure groove mechanical seal can be achieved. The dynamic pressure groove is prevented from being blocked and abrasion of the sealing end face is relieved. The seal ring can be applied to working conditions including solid particle media.

PendingCN108638670ADifficult to raise sharesImprove drying efficiencyOther printing apparatusEngineeringDigital printing
The invention belongs to the technical field of printing equipment, and in particular, relates to a digital printing and air sucking device and a digital printing machine. The digital printing and airsucking device comprises a printing platform and an air sucking cover plate; the printing platform is provided with a negative-pressure groove; the air sucking cover plate covers the negative-pressure groove, and is provided with multiple air sucking runners arranged side by side; each air sucking runner extends in a moving direction of a medium in a wave or sawtooth form; and multiple air sucking holes arranged in each air sucking runner in the extension direction. The air sucking area of the air sucking holes is changed from a hole form to a whole air sucking runner, so that the air suckingarea of the air sucking holes is increased, and the medium can be dried more uniformly; the dried medium is more smooth and not easy to drape; meanwhile, the drying speed is accelerated; and gaps between the runners can level the medium, so that the areas, recessed into the air sucking runners, of the medium can be leveled by the gaps between the runners during drying and curing, and the medium can be cured more smoothly and is not easy to drape.
