For manual hydraulic pump, and other related equipment have application users may understand, we will inevitably be some large and small faults of its use for some time, and thus have an impact on our work, we must find the problem solve the problem, which we can find the cause of the following three points: 1. Check the manual pump boom cylinder internal 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 significant manual pump station manufacturers, such as worn seals should be replaced. 2. Check the control valve. First clean the safety valve, check valve wear SYB-2 manual pumping stations, 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 non-standard manual pump station, then make adjustments, plus the pressure is still not tune up, then pump heavy wear. Manual hydraulic pump and hydraulic motor What is the difference between the two? 1) manual hydraulic pump is a motor mechanical energy into hydraulic energy converting means, output flow and pressure, hopes high volumetric efficiency; hydraulic motor is a fluid pressure energy into mechanical energy means, the output torque and speed, mechanical hope high efficiency. So, to say the manual pump stations, pump energy device, while the hydraulic motor is executed elements. 2) steering hydraulic motor output shaft must be able to forward and reverse, so its symmetric structure; and some hand pump (such as gear pumps, vane pumps, etc.) have a clearly defined steering, only one-way rotation, can not change the direction of rotation. 3) In addition to the hydraulic motor, the oil estuary, as well as a separate drain port; pump generally only into and out of the oil port (except axial piston pump), within which the oil leak and the inlet connected.
