1, the working fluid should be kept clean. It is recommended to install a filter with a filtration precision of 80 ~ 100μm on the oil suction pipe of the pump. The oil return pipe should be equipped with an oil filter with a filtration precision of not less than 25μm and periodically cleaned according to the oil pollution or replace. 2, hydraulic gear pump into the oil side if the filter, you should ensure that the effective filter oil flow rate should be greater than twice the maximum pump suction flow, and maintain smooth, to prevent blockage. 3, strict rules Before the start of the installation of the pump, you must grease the exhaust, so that the pump can turn on the oil in time to drive. It is best to release a pipe joint in the pressure pipe, move the power element to allow the oil to flow out until there is no bubble, and then tighten the pipe joint (this operation should pay special attention to press this treatment, the pump is not the initial operation Damaged the most encountered fault). After the installation of the pump should be no less than 10 minutes of no-load and short-time load operation. 4, gear pump in continuous operation under the maximum temperature shall not exceed 80 ℃, instantaneous operating temperature shall not exceed 120 ℃, so as to avoid premature seal aging.
