Germany Harvey piston pumps, hydraulic machinery BEST (certified), Harvey piston

Maintenance: (1) Check whether the scratches and corrosion phenomenon plunger, when necessary, replacement of new products. (2) Check piston pair cope with the situation. The plunger tip insert the plunger comprising a tilt of about 60 °, if the plunger can slow the decline in its role as a good fit. (3) Check the tightness of piston pair. Hold the plunger sleeve Harvey piston, two fingers to block the plunger tip and side inlet. With the other hand the piston cylinder 塞哈威 good quality, feel a greater attraction, relax immediately retract the plunger in place, show piston secondary seal is good, or should be replaced piston pair. (4) Check the oil valve Deputy vacuum ring worn a step or injuries phenomenon, when necessary, be replaced. (5) check out the situation with the deputy of the valve. Use your fingers to block the valve under the hole, with the other fingers to gently press down the valve when the valve finger from the upper end of time, it can automatically play back in place, indicating that the valve secondary seal is good. Otherwise should replace the oil valve deputy. (6) Check quite cylinder. Standard fuel pump body and the very cylinder gap between the piston pump 0 ~ 0.03mm Harvey preferred, such as more than 0.2mm, replace the parts. Gap (7) Check the plunger flange and the control sleeve between the grooves, should be 0.02 ~ 0.08mm, such as more than 0.12mm, you must replace the control units. Mechanical classification: piston generally divided into single piston, horizontal piston pump, axial piston pumps and radial piston pumps. Single-piston pump structures are mainly eccentric, plunger, spring, cylinder, two-way valve. Closed volume is formed between the piston and the cylinder bore. Eccentric rotation of a turn, reciprocates a plunger up and down, the downward movement of the suction, the upward movement of oil discharge. Oil pump volume per revolution a turn expelled called displacement, displacement is only concerned with the structural parameters of the pump.
