How should the axis of the river gravel pump be adjusted?
After the river pumping pump will change its axis after a period of use, how should the axis of the river pump be adjusted? The following is a detailed introduction:
Before the river pumping pump unit is used or used for a period of time, the axis of the river pumping pump and the motor or diesel engine will change. If the axes of the two are not adjusted in time, the
elastic ring of the coupling pin will be damaged frequently. If it is heavy, it will cause the pump shaft to break.
Then, on the construction site, how to adjust the axis of the coupling pumping unit of the river pumping pump under the condition of poor conditions?
One method is to fit the knife and the feeler. Find the outer circle of the coupling with the knife edge to ensure that each pair of couplings is flush in all directions, and the maximum error should be
no more than 0.1mm (Figure 1). Check the gap between each pair of couplings with a feeler gauge. The clearance should be greater than 1 mm, but the maximum error δ (δ = δ1 - δ2) is not more than 0.1 mm.
Another method is to use a magnetic dial indicator with a feeler gauge to find the positive coupling, fix the magnetic dial indicator to the outer circle of the coupling and drive the car, and place the
side of the dial indicator on the outer circumference of the opposite coupling. Above, watch the dial indicator beating should not be greater than 0.15mm (Figure c).
Check the gap between each pair of couplings with a feeler gauge. The clearance should be greater than 1 mm, but the maximum error δ (δ = δ1 - δ2) is not more than 0.1 mm.
Why is the slurry pump also called the sand pump?
In the field of seawater sand selection, slurry pump applications are also beginning to be recognized by customers. However, sand is selected in seawater and sand is dredged in the river. The slurry pump
is more easily called a sand pump and a dredging pump.
Although the name is different, it can be called a slurry pump in terms of structural characteristics and pump performance.
Therefore, in this seawater sand selection, we often call it a sand pump. In the river dredging, it is customary to call a dredging pump. Although the use of slurry pumps is extensive, the correct
Due to the limitations of the name of the slurry pump, some people in the industry are misunderstood. In fact, mud pumps, impurity pumps, dredging pumps, dredging pumps, etc. are all in the application
range of slurry pumps.
In the application process of the slurry pump, it is very important to pay attention to reasonable design, correct calculation, and appropriate selection.
