As a newcomer in the industry, the dry-milled pipeline centrifugal pump is a new product developed by Shanghai Hongdong Pump Industry. It is an improvement to the safety problems that have occurred in the past centrifugal pumps. This product is used throughout China and people are blue-eyed. There is a plus, but there is a lack of practical guidance on installation issues. The basic problems can be found in the installation manual. Others require consumers to worry. The following are some installations provided by Wuxi Xinjiuyang Pump Industry. Problem summary.
First, select the model
Dry-milling pipeline centrifugal pumps are divided into different models to cope with different operating environments, so first of all, we must determine that the selected model is consistent with the operating environment.
Installation height
Regardless of any centrifugal pump, pay attention to the installation height, that is, the linear length of the water source and the center of the pump impeller, called the vertical height. The height of the pump needs to be within the calculated value, that is, in the case of standard atmospheric pressure, the water temperature is Celsius, after a certain The experimental determination, and try to reduce the elbow fittings in the water inlet pipe to control the flow rate, minimize the amount of water, and the water inlet can not be directly connected to the elbow.
The tightness must be strong
An important issue to be noted during installation is the tightness. If the vacuum at the inlet of the dry-milled pipeline centrifugal pump is persecuted, the water flow may be reduced, the water is difficult to be pumped up, and the work is more difficult to carry out.
Inspection equipment
Before installation, check the equipment itself to see if there is any looseness in the fasteners of the unit, or if there is a casino blockage in the flow path of the pump body. If an abnormality is found, clean it in time, otherwise it may damage the pump body at the same time. During installation, the screws of each part must be tightened. After all the screws are completed, a comprehensive system inspection should be carried out. After installation, the pump shaft must be turned to see if there is any abnormal noise in the middle. Simply stuck, you need to disassemble the inspection or replace it with a new one.
The sales of dry-milled pipeline centrifugal pumps have been distributed in various cities in China. The seemingly insignificant installation problems above may actually affect the progress of the entire project. One more minute of inspection will provide an additional safety guarantee. Wuxi Xinjiuyang Pump Industry hereby calls for caution in installation, because 80% of the failures are not due to quality problems, but are caused by problems during installation but not discovered in time.
