The general process of how to run a hydraulic hand pump hydraulic hand pump is a manual mechanical energy is converted to liquid pressure to a small hydraulic pump station, in supporting the fuel tank and special tools can be made of various operations, such as starting heavy, curved, straight, cutting, riveting, assembly, disassembly and some construction, military construction. The main features of the hydraulic hand pump is manually powered, high-voltage, ultra-small manual pump station sales, easy to carry, easy to operate manually pumping stations, a 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, low oil spill back to the reservoir tube. 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 pressure needs to be reduced to zero is complete, open the unloading valve, the oil 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. For manual hydraulic pump, and other related equipment have application users may understand SYB series manual pump station, we will inevitably arise in a number of large and small faults of its use for some time, and thus have an impact on our work found that the problem would solve the problem, which we can find the cause of the following three points: 1. Check the manual pump action within arm cylinder leakage situation. The easiest way is to raise the boom, to see whether there is a significant decline in freedom. If you disassemble the fuel tank to check the whereabouts of obvious SYB-2S manual pump stations, such as worn seals should be replaced. 2. Check the control valve. First clean the safety valve, check valve wear, such as wear and tear should be replaced. If there is still no change after the valve is installed, and then check the control valve spool wear, the gap is generally limits the use of 0.06mm, badly worn should be replaced. 3, measuring the manual hydraulic pressure. If the pressure is low, then make adjustments, plus the pressure is still not tune up, then pump heavy wear.
