1. What should be paid attention to when installing pipelines?

①The distance between the oil suction pipe and the oil return pipe should be as large as possible. In any case, the oil return liquid is not allowed to be sucked away directly.

②The oil inlet pipe of the pump cannot be connected with the oil return pipe of the overflow valve.

③The oil drain pipe of each pump should be returned to the oil tank separately, and the same oil return pipe should not be shared with the system.

④The outlet of the oil return pipe is always lower than the oil level, and the minimum distance between the oil inlet pipe and the bottom of the oil tank is 50mm.

2. What should be paid attention to when installing the oil filter?

Use oil return filter or pressure oil filter as much as possible to ensure smooth oil suction. When using an oil suction filter, it is best to use it together with a negative pressure switch/pollution indicator to avoid suction.

3. What are the preparations before putting pump into use?

① Check whether the equipment has been installed carefully and cleanly.

② Fill the oil with the oil filter with the required filtration accuracy.

③Fill the pump with oil through the suction pipe or pressure oil pipe.

④Check whether the rotation direction of the motor is consistent with the rotation direction of the pump according to the pump model.

4. What are the precautions when it is put into use?

①Avoid starting the pump when there is no oil in the pump. Fill the oil port with oil before starting the pump, otherwise it may be damaged.

②The pump with an exhaust valve installed at the outlet of the pump should be exhausted first. If there is no exhaust valve, slightly loosen the pump outlet pipe joint to exhaust when there is no pressure.

③Avoid starting the pump with load.

④ Avoid starting the pump when the oil temperature is too low or too high.

5. How to operate the pump after it is put into use?

① Put the equipment into use and load the pump according to the equipment manual.

②After a period of running time, check the liquid in the tank: Are bubbles formed on the surface of the liquid? Is the oil level of the tank lowered below the oil standard value?

③ Pay attention to the change of noise during operation to judge whether air is inhaled.

④ Avoid running the pump under full load for a long time.

⑤The pump driven by the engine should avoid running at high or low speed for a long time.

⑥The oil filter of the pump suction pipe should be cleaned regularly.

⑦When starting at low speed, there is a limit to the maximum viscosity of the oil, otherwise the pump will not suck the oil.

⑧ The pump can only be operated under the permitted data, and only allowed to work in an intact state.

⑨Must comply with general and effective safety regulations.

⑩When doing any work on the pump, the equipment must be connected to a pressureless state.
