What is the reason for the severe vibration of the pump body of the screw pump
The screw pump is a very high-quality pump, which relies on the volume change of the sealed cavity formed by the screw and the bushing to inhale and discharge the liquid. It has the advantages of stable flow, self-priming ability, low noise, long life and reliable operation. It can transport high-viscosity media, and it does not form eddy currents and is insensitive to the viscosity of the media. So it is widely used today.
There are always some common problems when people use the screw pump. Of course, this does not explain the quality of the screw pump. Any equipment will encounter various problems during the use process, and these problems are generally caused by human beings or some other factors. . We must first check carefully to see if the parts of the screw pump are defective, find out where the problem comes from, and prescribe the right medicine.
For example, when using a screw pump, the pump body often vibrates violently or generates noise. What is the reason? Generally speaking, it is because the water pump equipment is not strong or the water pump equipment is too high; the ball bearing of the motor is damaged; the main shaft of the water pump is bent or is not concentric or parallel to the main shaft of the motor.
We don't need to be serious when encountering such problems, and this situation can also be dealt with. The first method is to stabilize the equipment height of the screw pump or the descending pump; correct the bent main shaft of the pump or adjust the relative orientation of the pump and the motor.
Introduction to the precautions recommended by the screw pump
The screw pump is a screw pump that needs to be primed before the first recommendation, and does not need to be primed when it is recommended again. It can automatically extract the gas in the suction pipe and transport the liquid normally.
A suction chamber is added at the inlet of the screw pump, and the suction pipe is above the center line of the impeller. After the pump is stopped, a part of the liquid remains in the suction chamber. When the pump is again recommended, it is recommended to enter the gas-liquid separation chamber added at the outlet to separate the gas and liquid, and the liquid returns. Go to the suction chamber until the suction tube is filled with liquid, and the liquid is transported normally.
Stainless steel screw pump is an energy-saving pump product developed by absorbing, digesting and improving relevant technical data at home and abroad. It has the advantages of compact structure, simple protection, high efficiency, and strong self-priming capacity adjustment. The screw pump pipeline does not need to be equipped with a bottom valve, and it is only necessary to ensure that the pump body has a quantitative liquid infusion before operation.
