How to prevent hydraulic hand pump glitches when using hydraulic hand pump or the installation process will use some common faults hand pumps, if these common faults that you know in advance, so that you can advance to prevent the installation again, this hydraulic hand pump installation, use is definitely a good thing, today small to put these common problems you summed up: According to the season to add or replace grades of oil to meet the requirements of the provisions of the oil, remove the foreign body inside the tubing Shenyang manual pump tighten a bolt or nut joints; hydraulic hand pump oil seal replace aging or damaged or "O" ring gasket; hydraulic hand pump to replace worn gear pump or pump bushings, wear flat minor when Admiral flat end mill. Its roughness tolerance 0.03mm; the sleeve on the end face of the hydraulic hand pump below the plane (normal less than 2.5 ~ 2.6mm) hydraulic hand pump, such as ultra-poor should be the next sleeve plus 0.1 ~ 0.2mm copper to Compensation hydraulic hand pumps, the installation should be put into the sleeve at the rear axle; unloading pieces and sealing ring must be installed in the inlet chamber, two sleeves in order to maintain balance. Unloading film seal ring should have a preload amount of 0.5mm; the guide wire should be able to simultaneously stretch the upper, lower sleeve toward the rotational direction of the driven gear is twisted by a small angle, so that the main, two driven gear sleeve machining plane close fit; rated pressure: 10MPa Rated Displacement: 20ml / second maximum hand force: ≤400N Weight: 17Kg Dimensions (mm): 800 × 200 × 350 oil storage: 10L single-stage pump single export SBD20D type manual The manual pump is mechanical energy into hydraulic energy of a small pump station.
