W-type single-stage direct-flow vortex pump is used to suck water and physical and chemical properties similar to the water used, the use of liquid temperature not exceeding 80 ℃, commonly used in boiler feed water, in shipbuilding, textile , Chemical industry, metallurgy, machinery manufacturing, aquaculture and so on. Now to say, W-type single-stage direct-flow vortex pump correct operation steps is what. W-type single-stage direct-flow vortex pump W-type single-stage direct-flow vortex pump the correct steps Start, stop 1, W-type pump. First check whether the bearing body calcium-based butter. If the storage time is too long, should open the bearing cover to check. See if it is 変 quality, such as found in deterioration, should be re-oil change before starting. 2, turn the coupling (direct pump can be removed after the motor blades 5 rotating blades). After verifying that the rotor components rotate easily and well evenly, check the levelness of the unit with a level gauge, and after leveling, properly tighten the coupling nut with the foundation. 3, set the motor insulation strength. If it is lower than 5MΩ, the motor may be damp or damaged. If it is damp, it can be flooded by itself after the motor runs for a period of time. Otherwise, the motor must be repaired or replaced to avoid damage to the pump due to poor operation. 4, test start: Jog motor, adjust the motor to the same requirements. 5, open the suction pipe valve, liquid guide to the pump body. Pump installation position higher than the horizontal position, the bottom end of the valve can be installed in the suction pipe. Off before starting. Fill the pump housing with the drawn liquid (suction path is shorter, the first start of water, after the liquid in the pump casing, no re-irrigation). 6, open the valve out of the pipeline, start the motor, open the pressure gauge. Adjust the pressure on the pipeline valve, the pressure gauge readjust to adjust. Never allow the pump to operate with the valve closed or with minimal flow. 7, parking. First off the pressure gauge, stop the motor. Then quickly close the pressure out and suction pipe valve. 8, a short time parking. If the ambient temperature is below the liquid freezing point, to vent the liquid. Long-term parking, pump ditch should be washed, oiled properly kept. Operation 1, during operation. Observe the running status of the unit. In particular, feel the motor temperature is too high. Split pump must also note that the bearing temperature should not exceed 70 ℃. For the former. The main solution is to check whether the pipeline is blocked or the valve is open. So that the pump pressure is too large: the latter mainly depends on the calcium-based butter is filled with appropriate. Is the bearing damaged or the motor and pump are out of focus? 2, found the fault should immediately stop working and check.
