BL Marine Horizontal Direct-coupled Centrifugal Domestic Pump

Overview

BL Series marine horizontal direct-coupled centrifugal pump, for the transport of water and physical and chemical properties similar to liquid water. This type of pump is BA type pump based on the improvement of the structure, has the advantages of small, light weight, simple structure and convenient handling characteristics. The performance parameters of BA pump with the same. Liquid temperature not exceeding 100℃, with mechanical seal. I produced BL type marine centrifugal pump impeller with silicon brass, a pump shaft is made of stainless steel.

Product use and maintenance

1. After starting the pump, check whether the running current of the motor and the operation of the water pump are normal. If there is any abnormality, stop the pump immediately. 

2. Check the pressure gauge at the outlet of the water pump. When the pointer of the pressure gauge reaches the rated working pressure and is stable, gradually open the outlet valve to make the pump work under the rated state as far as possible.

3. After the pump is filled with water normally, move the clutch handle installed for vacuum suction to the "off" position.

4. Check the pressure of the valve group. The pressure of the clean water valve group is about 0.8MPa, and that of the foam valve group is about 1.0MPa. If the pressure cannot be maintained, the pump outlet and return valve can be properly adjusted to control the pressure.

5. The temperature of the pump and motor bearing shall be checked frequently, the maximum temperature shall not exceed 75 ℃, and the working current of the motor shall be within the normal range.

6. After stopping the pump, restore all valves to the normal state according to the requirements of the valve opening and closing state diagram.
