Hydraulic Gear Pump Precautions For Use

Hydraulic Gear Pump Precautions For Use:

1. It is recommended to use L-HM46 anti-wear hydraulic oil in summer and L-HM32 anti-wear hydraulic oil or hydraulic oil with similar viscosity in winter. The back pressure of the gear motor drain port should not be greater than 0.4Mpa.

2. The working oil should be kept clean. It is recommended to install an oil filter with a filtration accuracy of 80-100um in the suction pipe of the pump and an oil filter with a filtration accuracy of 25um in the oil return line. It should be cleaned or replaced regularly according to the degree of oil contamination.

3. If there is an oil filter at the oil inlet of the oil pump, it should be ensured that its effective flow rate should be greater than twice the maximum oil suction flow rate, and should be kept smooth to prevent clogging. The capacity of the open fuel tank is greater than the flow rate of the oil pump for 3 to 4 minutes, and the capacity of the closed fuel tank is greater than the flow rate of the charge pump for 3 to 5 minutes.

4. It is strictly stipulated that before the installation of the oil system begins, oil must be filled and exhausted so that the oil pump can absorb oil in time when driving and rotating. It is best to loosen a pipe joint in the pressure pipeline and move the power component. Let the oil wave flow out until there are no bubbles and then tighten the joint (pay special attention to this operation, failure to do this is the most common cause of initial damage to the pump). After installing the pump, it should be operated with no load and short-term low load for no less than 10 minutes. Avoid starting and stopping with load.

5. The temperature of the oil pump should not exceed 80°C during continuous operation, and the instantaneous operating temperature should not exceed 100°C to avoid premature aging of the sealing components.
