Механична поддръжка на помпата с отворен вал

For plunger pumps that use a replenishing pump to supply oil, after 3000 hours of use, the operator needs to check the plunger pump 1-2 times a day to check whether the hydraulic pump is running normally. If the hydraulic cylinder speed drops or the car is stuck, the replenishing pump should be disassembled and checked to see if there are scratches on the edge of the impeller и независимо дали клирънсът на вътрешната зъбна помпа е твърде голям . за самозаблудни бутални помпи, маслото в хидравличното масло не трябва да бъде по-ниско от долната граница на маслената маркировка и по-голямото количество хидравлично масло трябва да се поддържа ., колкото по-голяма е чистота на хидравличното масло, колкото по-дълъг е обслужващият живот на хидрата на хидравлията, колкото по-голяма е чистота на хидравличното масло pump. The clearance of the disassembled bearings cannot be detected without professional testing instruments, and can only be visually inspected. If scratches or discoloration are found on the roller surface, they must be replaced. When replacing bearings, pay attention to the English letters and models of the original bearings. Most plunger pump bearings use large load capacity bearings. Purchase products of the original manufacturer and original specifications. If you change to another brand, you should ask experienced personnel to check the table to exchange them. The purpose is to maintain the accuracy grade and load capacity of the bearings. The service life of the plunger pump is related to the usual maintenance, the quantity and quality of the hydraulic Маслото, чистотата на маслото и т.н. . Избягването на износването на триещата двойка на буталната помпа от частици в маслото също е ефективен начин за удължаване на живота на буталната помпа ., когато замяната на части по време на поддръжка, оригиналните части трябва да се използват възможно най -много {.}}}}}}}}. better. If you buy cheap imitation parts, it seems to save money in the short term, but it brings hidden dangers and may cause greater harm to the use of the plunger pump. There are two types of distribution plates: plane distribution and spherical distribution. The friction pair of the spherical distribution can be repaired by grinding when the scratches on the cylinder body distribution Повърхността е сравнително плитка; when the grooves on the cylinder body distribution surface are deep, the grooves should be filled with "surface engineering technology" first, and then ground. Do not grind blindly to prevent the copper layer from becoming thinner or oil leaking out of the steel base. The plunger pump can also use the frequency converter to save energy. The engineer of Shanghai Zhengyi pointed out that in the actual production process, the plunger pump usually adjusts the working state by pressure or flow. When the actual pressure is greater than the required pressure, it is adjusted by the overflow valve to keep the working pressure stable and let the overflow valve release the excess. The motor is always running at full speed and repeatedly, and the power consumption remains unchanged. When the overflow is used to adjust the pressure and flow, some of the surplus overflows back to the original system, resulting in useless power in the plunger pump and low working efficiency. If the Chuangjie energy-saving frequency converter is used, the overflow valve can be closed, and the working pressure can be automatically adjusted by the energy-saving frequency converter itself to keep the working pressure stable and automatically track the pressure of the Оборудването . Автоматичният контрол се реализира, за да спести енергия . Най -голямото предимство на този метод за регулиране е, че може да намали потреблението на работна енергия на буталната помпа, а ефектът на пестене на мощност може да достигне повече от 30%.
