1, note that the suction pipe seal, the first three-dimensional screen should be filled in the suction pipe before pumping chamber pumping medium, and the use of pipe clamp rotation turn. Then start. Do not idle in the absence of medium, causing damage to the stator.
2, winter or alpine area pump, stop when not in use. Open the bottom plug. End discharge, to prevent freezing damage.
3, the use of the pump at any time to note the flow, pressure and other conditions, the job found that traffic, sudden changes in pressure or different sound, should promptly check and solve.
4, for high viscosity, crystalline, containing particles or corrosive media pump, after use, should be cleaned to prevent deposition or damage.
5, pay attention to the coaxial pump drive system, the factory, the pump and power side (including the base) have been adjusted. However, during installation, due to uneven foundation, tighten the anchor bolts, may cause the base to distort, causing the center of the coupling to shift. Should re-check the installation of coupling deviation: displacement △ × ≤ 0.3 mm, angle deviation △ ≤ 30.
Single screw pump installation 1, pay attention to motor steering, to prevent reverse 2, the outlet should be installed before the length of a slightly larger than the stator easy to remove the pipe, in order to facilitate the replacement of the stator.
3, the pump inlet in the vertical direction, the outlet in the horizontal direction, so that the seal can work under negative pressure to reduce the pressure of the sealed chamber, spin: from the direction of exit counterclockwise rotation. In addition, import and export of the pump flange (pipe) should not afford the pipe weight, so the pipe should be set at the support point.
4, the pipeline must be cleaned before installation to prevent foreign body damage to the stator, rotor, and cause blockage.
5, the pipe diameter should be as large as possible with the pump diameter matching, too small inlet diameter will lead to insufficient supply of the pump, thereby affecting the pump discharge and output pressure. In severe cases, pipeline vibration will be caused, causing early damage to the stator. Too small an outlet pipe diameter will result in unnecessary loss of outlet pressure.
6, for mechanical seal shaft seal, should pay attention to the introduction of fresh water, lubricating oil or other coolant.
For single-end seal shaft seal, if the medium is viscous, easy to solidify the crystallization medium should pay attention to stop cleaning the mechanical seal, to ensure the normal operation of the mechanical seal is required. There is an inch pipe thread interface on each side of the sealed box, and an outlet metering connector is provided at random. The inlet line of the circulating liquid is directly connected to the sealed box. At the outlet side of the sealed box, an outlet restrictor is connected Maintaining a certain pressure inside the sealed adaptable box is crucial) and then to the outlet line. Work, you should start circulating fluid, start the pump; first stop the pump, then close the circulating fluid.
Single screw pump test run 1, single screw pump should avoid dry running, even a very short time will cause stator damage.
Before starting the pump, the medium to be delivered is injected into the suction chamber of the pump (if the medium concentration is high, it is injected after dilution). To ensure lubrication of the rubber stator. When the pump is stopped, enough fluid should be left in the suction chamber. Remember to design pipelines should be given special consideration.
2, before starting, once again check; such as the belt cover, a variety of pipeline valve opening and closing situation. When correct, before starting.
3, if the media used in the freezing environment, in order to prevent the fissure pipeline, the screw below the screw out. To vent the media.
4, single screw pump can not work when the valve is closed, to avoid the pressure of the positive displacement pump caused by pipeline rupture and pump damage. Especially in the transport of hazardous materials, the installation of pressure switches and other safety devices is particularly important.
5, the pump should be instantaneous power to confirm that the pump turned and the same direction as shown.
6, easy to transport sediment, easy to cure medium, should be regularly cleaned pumps and pipelines.
7. For pumps that have been stored for more than two years, all the rubber in the pump should be replaced (including the stator) to ensure normal and safe operation of the pump so as to prolong the service life of the pump.
