During installation and use, the first thing to notice is that the centrifugal pump is integrated with the motor. It is convenient to install and does not require effortless alignment. Just tighten the anchor bolts during installation and secure the centrifugal pump to prevent the pump body. Vibration affects the performance of the pump. Secondly, in daily use, in order to facilitate the use and maintenance, it is necessary to install a regulating valve on the inlet and outlet pipelines of the pump, and then install a pressure gauge at the outlet of the pump so that the flow rate and use status can be grasped from time to time. To ensure the normal operation of the centrifugal pump and prolong the service life of the pump. Once again, the horizontal centrifugal pump should be equipped with a bottom valve when it is used for the suction process. Avoid as many bends as possible at the inlet pipeline. Water leakage and air leakage must not occur. The management weight of the centrifugal pump must be There is a separate support body to avoid deforming the pump body and affecting its service life. Fourth, after the centrifugal pump is installed, try to fluctuate the pump shaft and check whether the impeller has friction noise or seizure. Once these phenomena occur, the pump body should be disassembled and the reason should be promptly checked to remove the obstacles in time to avoid running the pump. The impeller and pump body are damaged.
After installing the horizontal centrifugal pump, some matters should be paid attention to when starting. First of all, be sure to fill the pump with liquid before the pump starts, until the top of the pump shell liquid. At the same time, the outlet valve is closed, so that the pump is kept in the condition that the flow rate is zero, so as to prevent the motor from burning out due to overload. After the pump is turned on, gradually adjust the outlet valve until the desired flow rate. Secondly, during the operation of the pump, it is necessary to frequently check whether the packing layer is exposed to heat leakage, and when the flow needs to be changed, it is controlled by adjusting the degree of opening and closing of the outlet valve of the pump, although this will cause the fluid resistance to increase and the loss of part of the Power, but it can achieve rapid adjustment of the flow, keep changes to meet production needs. Thirdly, the centrifugal pump must pay attention to the adjustment of the flow in the pump inlet valve, because it will cause the occurrence of “cavitation†phenomenon. Once the “cavitation†occurs during the operation, the pump body will be affected. The vibration occurs due to the impact, resulting in a decrease in the flow rate, and even in a serious case, the centrifugal pump may not work properly. Finally, when the centrifugal pump stops, it is necessary to close the outlet valve first to prevent the fluid from flowing back and causing the impeller nut to loosen. If the parking time is long, the liquid in the pump and the pipeline must be kept clean to avoid corrosion of the pump body and winter freezing.
Having mastered the above correct use method, not only can reduce the energy consumption, but also can prolong the service life of the horizontal centrifugal pump, and the users should keep in mind.
PVC High Speed Door are designed for indoor use and ensure rapid handling operations between different areas that should remain separated. These safe and efficient industrial doors are made of a shaped steel frame and covered with PVC. These high speed doors are safe and efficient and consist of a shaped steel frame covered with PVC. Safety is ensured by their photocells and barriers.
High speed doors protect us from harm, save energy and help us to separate processes for optimal productivity. A high speed door's most important job is to simply open and close quickly and safely every time you need it.
The high speed pvc roll shutter door require high strains, caused by the high operating speed and the frequency of openings, have to be taken into account during construction. In the same way, basic conditions like size and installation location add up to considerable requirements regarding safety and control technique.
