Maintenance and repair of D-type horizontal multistage centrifugal pump

D-type horizontal multistage centrifugal pump maintenance is mainly from the period of suspension and operation, D-type horizontal multistage centrifugal pump maintenance and repair requirements are as follows:
D-type horizontal multistage centrifugal pump, the series of pumps horizontal multistage centrifugal pump, using the national recommended high-efficiency energy-saving products, hydraulic model, living in the industry-leading technology. D-type horizontal multistage centrifugal pump with high efficiency, wide range of performance, safe and stable operation, low noise, long life, easy installation and maintenance.
For factories, mines, cities, power plants, petroleum, chemical, light Gong, environmental protection of drainage, farmland irrigation and drainage and various water conservancy projects. D-type horizontal multistage centrifugal pump is more common, the material is generally cast iron. Therefore, we can see D-type horizontal multistage centrifugal pump is widely used, but also used in more occasions, so we need to D-type horizontal multistage centrifugal pump has a good maintenance and repair, to horizontal and more Centrifugal pump operation safe and stable, long service life.
The following is the maintenance, inspection requirements:
1.D horizontal multistage centrifugal pump maintenance aD horizontal multistage centrifugal pump replacement of old horizontal multistage centrifugal pump replacement;
Replace horizontal multistage centrifugal pump oil (pump thrust bearing box);
Monthly water flush horizontal multistage centrifugal pump water guide bearing, the time is about 2 minutes;
Rotate pump rotor at the same time;
Check the horizontal horizontal multistage centrifugal water pump system, check the fasteners are loose.
bD horizontal multistage centrifugal pump to check the horizontal multistage centrifugal pump packing leak conditions;
Check horizontal multistage centrifugal pump lubrication water pressure;
Check horizontal multistage centrifugal pump lubricant and bearing temperature;
Do a good job log, such as horizontal multistage centrifugal pump has more trouble to record in detail.
2.D Horizontal Multistage Centrifugal Pump Maintenance a. During the inspection of the D-type horizontal multistage centrifugal pump, the motor control switch must be in the "closed" position and hang the warning sign to avoid any personal injury.
b. In the D-type horizontal multistage centrifugal pump demolition should be marked with the parts at the coordination so that the installation can be carried out smoothly; D-type horizontal multistage centrifugal pump demolition of small parts and fasteners with the box Install well, make a mark, indicate the premises; D-type horizontal multistage centrifugal pump removed parts clean, coated with anti-rust oil, painted surface if there is rust, we must eradicate rust, re-painted; Multistage centrifugal pump "O" ring, packing, rust fasteners can not be reused, ready spare parts.
