How to improve the operating life of hydraulic gear pumps

The HYDRAULIC GEAR PUMP is driven by an independent motor that effectively blocks upstream pressure pulsations and flow fluctuations. The pressure pulsation at the outlet of the HYDRAULIC GEAR PUMP can be controlled to within 1%. If we want to increase the operating life of the HYDRAULIC GEAR PUMP, we need to take certain measures

Daily maintenance of HYDRAULIC GEAR PUMP

Disassembly and cleaning of HYDRAULIC GEAR PUMP, raising and lowering of temperature, and starting and stopping should be operated strictly by the regulations to avoid undue losses. In use, attention should be paid to keeping the population pressure of the pressurized HYDRAULIC GEAR PUMP stable, so that it has a stable volumetric efficiency, to facilitate the operation of the HYDRAULIC GEAR PUMP itself and the stability of the downstream spinning quality. The population is negative pressure packing shaft seal HYDRAULIC GEAR PUMP, which should keep the pressure at the stuffing box higher than the external atmospheric pressure. When the back pressure decreases, the pressure at the stuffing box should be adjusted in time, otherwise, the HYDRAULIC GEAR PUMP will inhale air and cause the cast strip to break, which will affect the cutting and lead to the discharge of the cutting machine. And the temperature of the thermal media jacket should be checked frequently, and the thermal media temperature of the main body and the front and back cover should be kept consistent. Each time the output is increased, the output, speed, out and inlet pressure, and current value at that time should be recorded, and the data before and after should be compared and carefully analyzed so that abnormalities can be found as early as possible and dealt with in time.

Cost-effective measures for using HYDRAULIC GEAR PUMP

Because the HYDRAULIC GEAR PUMP body operates at high temperatures, hinge supports should be provided on the piping during cold installation to prevent piping displacement after warming. Our coupling joint must be hot-corrected after the HYDRAULIC GEAR PUMP body heats up to avoid additional torque caused by the operation. when starting the HYDRAULIC GEAR PUMP, when no pressure is formed at the outlet, do not blindly speed up to prevent premature damage to the shaft or bearing. When cleaning and shifting, do not use HYDRAULIC GEAR PUMP to deliver cleaning fluid, should remove the inner parts and install it again after the end of shifting, so as not to mix foreign substances in HYDRAULIC GEAR PUMP. HYDRAULIC GEAR PUMP body thermal medium jacket temperature can be slightly lower than the thermal medium temperature of the front and rear jacket casing. Because the melt viscosity and shear rate a decreasing function of the relationship, the gear extrusion, and bearing shear will make the melt temperature after HYDRAULIC GEAR PUMP rise 3 ~ 5 ℃, reduce the temperature of the thermal fluid can prevent the melt degradation.
