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, 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, tighten the joints bolts or nuts; replace the hydraulic hand pump aging or damaged oil seal or "O" ring gasket; hydraulic hand pump to replace worn gear pump or pump sleeve, slight wear at the 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 closely fit the general process of hydraulic hand pump to run hydraulic hand pump is a small hand pump stations pumping station price manual mechanical energy is converted to liquid pressure energy in supporting the fuel tank and special tools case You can make a variety of operations, such as lifting, bending, straightening, cutting, riveting, assembly, disassembly and some construction, military construction. The main features of the hydraulic hand pump is manually powered, high-voltage, ultra-compact, easy to carry, easy to operate, wide range of applications. Working process of hydraulic hand pumps roughly divided into the following phases: liquid-filled hydraulic hand pump at the beginning of working fluid is pressed into the high and low pressure piston check valve into the cylinder through the high and low pressure check valve, when the pressure rose to 1MPa when the low pressure valve opens non-standard manual pumping stations, low oil back to the reservoir overflow pipe. In the above-described step-up is based on the high-pressure piston continues to operate, the pressure is gradually increased when the pressure exceeds the rated pressure 63MPa, the high pressure valve is opened, high pressure oil from the high-pressure valve back to the reservoir overflow pipe, pressure is always kept at 63MPa. Pressure valve is a safety valve. In the course of their work as a result of the work function of the cylinder volume will be reduced, so be ready to shake the handle, maintain the desired working pressure until the end of the work. Hydraulic hand pump needs to be completed manually pumping station pressure reduced to zero credibility manufacturer unloading valve open, fluid flow back into the reservoir tube, complete the uninstall job. Oil-filled, boost, work process is actually inseparable, just shake the handle can complete these three processes.
