石油矿场用的往复泵凡尔,通常是在高压下输送水泥浆、钻井泥浆等磨砺性液体。磨砺性液体在高压下通过凡尔时,凡尔和凡尔座很容易被严重磨损,经常需要更换。凡尔和凡尔座的结构,应该满足快速拆换的要求。这一点,在固井作业使用的泵上,显得更为重要。因为如果在注水泥浆过程中,不能在很短时间内把发现漏泄的凡尔和凡尔座更换好,水泥浆就有初凝的危险。 Reciprocating pumps used in oil mines Vernal usually convey rough water such as grout and drilling mud under high pressure. Whetted liquids pass through Versail at high pressure, the Versailles and Versailles are easily worn out and often need to be replaced. The structure of Versailles and Versailles should meet the requirements of quick dismantling. This is even more important with the pump used for cementing operations. Because if in the process of water slurry, can not be found in a short time leaked Versailles and Versailles seat replacement, there is the risk of initial setting cement slurry.
