HL Series Horizontal Pipeline Pump
The Operating Principle of Feiyang Hailong HL 80-40 Pipeline Pump:
The water is thrown out by centrifugal force in physics of the pipeline centrifugal pump. The pump before starts working, the pump body and the water inlet pipe is filled with water, and entered the stable vacuum, then the motor power of the impeller becomes ?rotating quickly, the water pump is driven with the rapid rotation, when rotating to a certain speed, water will be under the centrifugal force to fly out, and the formation of the central region of the impeller vacuum. A large amount of water with the function of atmospheric pressure are pushed into the inlet pipe. The pipeline pump is such a cycle of work. In the use of pipeline pump, what we should pay attention to is: centrifugal pump must be filled with water to start before, otherwise the pump pipeline pump has suction may not be able to complete the work then leading to the pump body heat, vibration, water pump and other phenomenon, serious problems may also do some damage to the pipeline pump.
Working Conditions:
1, Suction pressure is less than 1.0MPa while maximum working pressure of the system no less than 1.6Mpa, the pump suction inlet pressure and the pump head is less than 1.6Mpa, while pump hydrostatic test pressure of 2.5MPa.
2, The ambient temperature is less than 40 ℃, and the relative humidity is less than 95%.
3, The liquid in transporting does not contain solid particles, or contains solid particle size can not exceed 0.1% of the unit volume, particle size is not greater than 0.2mm of the liquid.
Maintenance Attention in Use of Pipeline Pump:
1, The pipeline pump is best to use the ambient temperature of 40 ℃,when running the process, the maximum temperature of the bearing can not exceed 80 ℃.
2, The bearing lubricating oil should be replaced or supplemented. When adding lubricating oil, pay attention to observe the oil level and appropriate level must be in the oil standard center line.
3, Pipeline pump body water diversion plug screw, filling water (or lead paste).
4. Close the outlet pipe of the pipeline and the outlet pressure gauge and the imported vacuum gauge.
5, Move the pump motor, check the motor turning is right or not.
6, Start the pump motor, when the normal operation of the pipeline pump, open the outlet pressure gauge and imported vacuum pumps, as it shows the appropriate pressure, gradually open the valve, and check the motor loading.
PY-GD Series Injection Pump
Fuel injection pump series injection cabinet seal type pump?is a single-stage single suction pipeline centrifugal pump, compared with the ordinary type centrifugal pipeline pump, fuel injection pump has good sealing performance, independence of the mechanical sealing oil chamber can effectively protect mechanical seal is not affected by the working fluid corrosion or particle wear, eliminate the damages of the mechanical seal leakage defects to the centrifugal pumps. So as to make its use more widely, not only can be used for refrigeration, air conditioning system, cooling tower, spraying garden, fire and other general water supply system, and more suitable for water curtain spray cabinet working environment of oil, ethylene glycol solution and other physical chemistry with small granular media.
HL Brand Series Horizontal Pipeline Pumps
Feiyang brand horizontal pipeline pump, technical personnel of the company pumps the United Nations experts selected the excellent hydraulic model and using is type centrifugal pump performance parameters, in general horizontal pipeline pump based on ingenious combination of design to made, and the use of temperature and medium in different alg basis derived from the application of hot water, high temperature resistant corrosion chemical pump,oil pump.
