With the continuous development of modern industrialization, we use vacuum pumps more and more frequently. Oil return often occurs during use, which has also caused some troubles to our enterprise's development and production. Next, I will analyze the measures to prevent oil return of vacuum pump: 1. The static sealing part of shaft seal shall be firm and replaced in time. 2. Move the oil tank and exhaust valve to the side to reduce the oil level and reduce the amount of oil. 3. The plane of the vacuum pump base shall be flat, and the valve plate shall be elastic. 4. Separate the oil near the exhaust valve from other oil, and the oil level is only slightly higher than the partition wall. 5. Add a pipe into the oil hole so that the oil level is only slightly higher than the oil inlet. 6. The check valve mechanism of the vacuum pump is set to automatically close the oil inlet hole when the pump is stopped. 7. Set the oil pump and auxiliary mechanism to cut off the oil circuit when the pump is stopped. 8. Its pump port is equipped with an inflation valve. For the above small series, we provide measures to prevent the oil return phenomenon of vacuum pump. In the ordinary actual operation and use, doing these work well can effectively avoid the oil return phenomenon and ensure its normal operation.

By the start of 2020, Grizzlies guard Ja Morant had already put all of the active NBA Rookie of the Year contenders Chris Iannetta Jersey behind him.Morant enteredNew Year's Day averaging17.4 points, 6.5 a sistsand3.2 rebounds per game while generating buzz with his midair acrobatics. No one else came close to that production.But the long-awaited debut of Pelicans forward Zion Williamson in January could make Rookie of the Year discu sions interesting depending on how the final two months of the campaign unfold.Is it po sible for someone who mi sed about three months to an injury to claim a season-long award? Barely, andthe circumstances would need to be extraordinary and include an Chris Rusin Jersey unlikely playoff berth for New Orleans. There remains the slimmest of chances, though, given Williamson's game-changing impact on the floor and the flair with which the Pelicans have playedin recent weeks.MORE: Before this week, Williamson had endured very few road bumps to start his career. He showered 3-pointers in his debut, and then showed his dominance inside by recording double-doubles against the playoff-bound Carlos Gonzalez Jersey Celtics and Rockets.But earlier this week in a 120-108 lo s toMilwaukee, Williamson finally came back to earth with a 5-for-19 shooting effort in which he was completely dominated byGiannisAntetokounmpo. Williamson started ice-cold in the nationally televised tilt, not scoring until almost six minutes into the action, when he tipped in a Jrue Holiday mi s. He struggled to move Antetokounmpo or Brook Lopez with his large frame and was left grasping at air on a couple of offensive moves byAntetokounmpo. His 20-7-5 line felt empty given his inefficiency.Giannis is in killer mode tonight.He's teaching Zion a few le sons Sporting News (@sportingnews) Williamson went 32minutes Tuesday and Bryan Shaw Jersey 25 minutes Thursday, and he has now exceeded 28 minutes in four of his last five contests. Injury-related playing time limitations have been lifted. He is averaging 19.8 points and 7.5 rebounds per game, and he could improve upon that stat line as he settles into the league. By comparison, Morant is averaging 17.4 points, 7.0 a sists and 3.4 rebounds per game.There are 30games left to play for the Pelicans and 31games remaining for the Grizzlies. That would give Williamson a maximum of 38total games played this season and Morant a maximum of 71, though neither should be expected to compete in every single contest. Following a win over the Bulls on Thursday night, New Orleans (21-31) is 5.5games out of a playoff spot. Memphis (26-25) Nolan Arenado Jersey occupies the No. 8 seed and holds a multigame cushion over the rest of the Western Conference pack.Should the Grizzlies make the playoffs, Morant will win Rookie of the Year. Should the Pelicans mi s the playoffs, Morant will win Rookie of the Year. Should Williamson averagefewer than 20 points and 10 rebounds the rest of the way, Morant will win Rookie of the Year.If none of those conditions materialize, however, Williamson will have a fascinating case for the award.Here is how the NBA Rookie of the Year race currently stands:NBA Rookie of the Year rankings1.
