Grundfos Pumps, one of the world's leading manufacturers of PUMP products, produces 10 million units a year. Circulation pumps (UP), submersible pumps (SP) and centrifugal pumps (CR) are the three main types of pumps. Grundfos Pumps Maintenance Grundfos Conventional Pumps Maintaining and Maintaining Points 1. The pump can not be jogged to check positive and negative rotation when the pump is in an anhydrous state. 2. The pump should be carefully rinsed before cleaning the pipeline to ensure that no foreign body into the pump, the pump must be filled with water before starting for the first time to start running. 3. Pump import and export must be installed pressure gauge, pressure gauges in the case can not be debugged. 4. The water pump must be in place before commissioning. Second, on the vertical booster pump pressure control this piece, we are through the pump outlet valve to open to adjust the pressure difference, if the outlet without a pressure gauge, we can not determine whether the pump work in our pressure curve, so the pump Fault can not be judged correctly. Such as when a long time when the valve is fully open, it will cause the pump to run a large flow rate to overload the pump near the head will produce bubbles, the heat generated by the mechanical seal can not be taken away due to overheating carbonization, 0 ring deformation caused by leakage . 1. 1. After the water pump is installed, the inlet water level must be higher than the water pump (if it is lower, the bottom valve must be installed), and install the pressure gauge between the pump outlet and the valve. 2. 2. Before using the pump, Water before starting the pump; 3. 3. Before starting the motor nameplate and wiring box wiring diagram wiring requirements, set the thermal protection according to the rated current of the motor; 4. 4. After the start of steering and according to the curve through the switching valve to adjust the pump (The outlet pressure minus inlet pressure complies with the name plate), the motor running current should be within the rated current; 5. The pump body part is under normal circumstances, maintenance-free; 6. 6. 11KW Thousands of bearings need to add a grease (high temperature lithium base fat), the motor has a specific label; (when the production of motor) 7. 7. 11KW following motor bearings are maintenance-free, without refueling, under normal circumstances every operation 20,000 Hours need to be replaced 8. Pump long-term need to be under constant circumvention of the pump to prevent the machine seal sticking Grundfos Pump Repair Grundfos Pumps in life is very common, but often because of some wrong operation or Wrong method of maintenance guide Many Grundfos Pumps and did not reach the life time, it does not work. Today, Xuzhou Nuobo Electrical talk to you and Grundfos pumps maintenance methods. 1, in order to extend the service life of Grundfos pumps, first of all, we must ensure that the correct method of operation. Wrong method of operation can lead to loss of deformation of the parts inside the machine, reducing the life of the pump. 2, Grundfos pumps on the pump body set up a lubrication door, regularly injected into the lubrication of the lubrication of the machine is the basic maintenance. However, the same need to disassemble the body, and some of the parts related to lubrication, to reduce wear and tear. 3, corrosion is also leading to a major reason for the pump life reduction. Corrosion first of all is the pump body itself, while reducing the compressive strength, thereby reducing the service life. Therefore, we must ensure that the pump to work in a clean environment, to prevent the pump body in the humid air for a long time, and thus corroded. The above is from Xuzhou Nuobo mechanical and electrical finishing Grundfos pumps repair methods, reproduced please specify: Grundfos Pump http:// [Editor's note] In order to improve the service life of Grundfos pumps, professional maintenance methods are indispensable. So, needy users quickly get up to this new skill bar. Internet Industry (Xiamen) Technology Co., Ltd.
