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 at syb2s manual pump, remove the foreign body inside the tubing 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), such as ultra-poor should be added in the next 0.1 ~ 0.2mm copper sleeve to compensate for installation When put into the rear axle should be set in; unloading pieces and seal 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; front hydraulic hand pumps which preparations hydraulic hand pump function is to power machine (such as electric motors and internal combustion engines, etc.) of mechanical energy into fluid pressure energy. Output flow can be adjusted as needed is called variable pump Harvey manual pump, the flow rate can not be adjusted is called a metering pump. Hydraulic systems commonly used in pump gear pumps, vane pumps and piston pumps three kinds. Before installing the hydraulic hand pump, the pump should be carefully examined and import pipeline runner no debris (especially electricity, gas welding slag), to prevent their entry into damaged parts of the pump in the pump, even lighting vortex impeller blades. Resulting in flow, pressure decreases syb2 manual pump, or no flow, pressure.
