The purpose of flushing is to prevent the accumulation of impurities, to prevent the formation of airbags, maintain and improve lubrication, etc., when the temperature of the washing fluid is low, both cooling. Now to introduce pump under the mechanical seal washing method and features. Pump mechanical seal pump mechanical seal washing method and characteristics of a flushing 1. Positive flushing (1) Features: The use of the host is sealed working fluid from the pump outlet through the pipe into the sealed chamber. (2) Application: For cleaning fluid, p1 slightly larger than p into, when the temperature is high or impurities, can be set in the pipeline cooler, filters, etc. 2. Backwash (1) Features: The use of the host is sealed The medium, introduced from the outlet of the pump into the sealed chamber, flows back into the pump inlet through the pipe after flushing. (2) Application: for cleaning fluid, and p into 3. Full flush (1) Features: The use of the host of the sealed medium from the pump outlet through the pipeline into the sealed chamber, rinsed back through the pipeline back to the pump Entrance. (2) Application: The cooling effect is better than the first two, which is used to clean the fluid and p1 and p are close to p and p. Second, the characteristics of external washing: the introduction of external systems and sealed media compatible cleaning fluid to the sealed chamber for flushing. Application: External flushing fluid pressure should be greater than the sealed medium 0.05-0.1MPa, suitable for medium temperature or solid particles of the occasion. Flushing fluid flow should ensure that take away the heat, but also to meet the needs of flushing, will not produce erosion of the seal. To this end, the need to control the pressure of the sealed chamber and the flow rate of flushing, general cleaning flushing fluid flow rate should be less than 5m / s; slurry containing particles of less than 3m / s, in order to achieve the above flow rate value, differential pressure expansion should read: pump valve pipe fittings exhibition 2016 exhibition of information industry, Internet (Xiamen) Technology Co., Ltd. author: Asian pumps network editor: Yao Xiaoxia (QQ / micro letter:) http: //beng.liuti. cn / (Service Hotline:)
A Spray Gun is a power tool with a compression-free storage tank designed to mechanically atomise liquids, pastes and powered substances, mainly for coatings. DIT spray guns are airless pressure guns equipped with an electromagnetically powered piston pump. The pump operates at 100 strokes per second. The paint is taken in during the intake stroke and expelled through the nozzle during the pressure stroke.
