Piston pump service life
Piston for the principle of introducing a plunger, a piston pump with two one-way valve, and in the opposite direction, the direction of plunger movement to a negative pressure occurs when the cylinder, then a one-way valve to open the liquid is drawn cylinder, piston movement in the other direction, the liquid is compressed to open another one-way valve, sucked the tank is drained. This work formed a continuous row movement after oil.
Piston length of life, and the usual maintenance, quality and quantity of hydraulic oil, oil cleanliness and other related. To avoid the pellet on the piston friction caused by wear and other vice, but also an effective way to extend piston life. Replacement parts in the repair should be used in the original production of parts, these parts are sometimes imitation parts prices than other more expensive, but better quality and stability, if the purchase price of cheap imitation parts in the short term appears to be cost savings, but this brings out the hidden dangers of the piston may cause more damage to use.
A flat valve plate assignment and two forms spherical assignment. Spherical Flow of friction pairs, face scratches in the cylinder with relatively shallow stream, through the grinding means to repair; cylinder with flow surface grooves deeper, they would first use of "surface engineering" means filled trench, then grinding not blindly grinding, to prevent leakage of the copper layer thinning or steel base.
