Hydraulic hand pump glitch how to prevent hydraulic hand pump when used during installation or use some common faults, if these common faults 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 hydraulic hand pumps, today small to put these common problems you summed up: Grades according to the season to add or replace oil to meet the requirements of the provisions of the hydraulic hand pump oil at how much money, remove oil foreign body inside the tube, tighten the bolt or nut joints; hydraulic hand pump replacement of aging or damaged oil seal or "O" ring gasket; hydraulic hand pump to replace worn gear pump or pump bushings, wear light in flat end mill will be smooth. 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; to strengthen the hand pump hand pump maintenance measures to be taken hydraulic hand pump manufacturers in the course, because of improper use or normal wear and affect the life of use, and therefore the need to strengthen the use of daily maintenance! Here we asked the experts to talk about the use of a hand pump to pay attention to what: Hose temporary use of prone to aging, need special attention, regular checks of periodic replacement. And around the plunger valve at each hand pumps may not have the presence of the dirt, the need for timely clean, clean the pump often insist ministries. Operating personnel, strict compliance with the use of precautions. Hand pumps working fluid for the kinematic viscosity of 20-28 centistokes, such as YB - N32 hydraulic oil, non-alcohol, water, glycerol, sesame oil, brake fluid, engine oil for ordinary working fluid. The working fluid must 120--160 mesh layers of filter clean. Shall not bump phenomenon, bar Tighten Texas hydraulic hand pump, should be used gently, so as not to damage the threaded. Non-painted exterior coated with a layer of petroleum jelly, which can prevent rust when not in use. Dry, room temperature suitable for storage, should not boxed.
