Send the purpose with circulating flushing washing lotion.
On the basis of the technical conditions of existing slush pump, in the scope used and convenience of mud slurry pump cylinder jacket
Many deficiencies being still present, for most of mud slurry pump cylinder jacket during use, the degree being worn is serious, and never one
The processing body planted, while good method solution never is carried out to the pressure of inside, because cylinder sleeve is direct and mud
Contact, easily worn and corroded by the small sand grains in mud and acid, alkali lye at work, cylinder sleeve internal diameter is become big, cylinder sleeve
Produce thorn leakage with the sealing of piston space, pressure reduces, until cylinder sleeve is scrapped, cylinder sleeve be can not reuse disposable quick-wear part,
The length in its life-span directly affects normal operation and the drilling cost of rig.
