Nothing is set in stone, as the manual hydraulic pump design is the same, always in the same position would be eliminated Shenyang hand pumps, so we have to continue to study and improve! (L) Improved manual pump design. After much argument, and finally the use of advanced priority valve with load sensing hydraulic steering gear in the form of the new system in accordance with the steering requirement to assign priority to the hydraulic hand pump flow, regardless of load size, wheel speed level can ensure oil supply ample, the remaining part can all work equipment supply circuit using a hydraulic hand pump, thus eliminating the steering circuit oil caused by excessive power loss and improve the efficiency of the system manual pump, reducing the hydraulic pressure of work. (2) optimize the design of the boom cylinders and hydraulic modeling, reduce system operating pressure. By optimizing the computing boom cylinder with standard series 80/4. Displacement hydraulic pump by 10ml / r increased to 14ml / r, the system set pressure is 14MPa, to meet the boom cylinder lifting force and speed requirements. (3) hand pump should also be noted in the course of the proper use and maintenance of loaders, hydraulic oil regularly add or replace, maintain the cleanliness of hydraulic oil, strengthen the routine inspection and maintenance. Product Name: SSD1 pressure hand pump Product description: High rated pressure: 150MPa high pressure rated Displacement: 1.2ml / second low pressure rated pressure: 3MPa Low Rated Displacement: 9.8ml / second maximum hand force: ≤500N storage tank: 3L Weight: 12KG Dimensions (L × W × H): 700 × 140 × 140mm hydraulic hand pump hydraulic force _ Lu (certified) _ manual pump is provided by the Texas Lu force hydraulic machinery plant.
