Routine maintenance of vertical multi - stage centrifugal pumps

In recent years, China's centrifugal pump industry has developed rapidly, benefiting from the continuous improvement of production technology in the centrifugal pump industry and the continuous expansion of the downstream demand market. The centrifugal pump industry is very optimistic about the development situation in the domestic and international markets.
    China's centrifugal pump industry is facing a new development situation, due to the increasing number of new entrants into the enterprise, the upstream raw material prices continue to rise, leading to lower profits in the industry, so China's centrifugal pump industry market competition is becoming increasingly fierce. In the face of this situation, the centrifugal pump industry industry enterprises should actively respond, focus on cultivating innovation ability, and constantly improve their own production technology, strengthen the competitive advantage, at the same time centrifugal pump industry enterprises should fully grasp the industry market trend, Continue to learn the industry's latest production technology, to understand the industry's national policies and regulations to grasp the same industry competitors in the development of the dynamic, the only way to enable enterprises to fully understand the industry's development and their own position in the industry, and to develop the right Development strategy to enable enterprises in the brutal competition in the market to obtain a leading edge.
    DL vertical multi-stage centrifugal pump is a kind of centrifugal pump, the pump used in the structure of the vertical, sub-form. So that vertical multi-stage centrifugal pump safe operation, smooth, long life, small footprint, safe and easy maintenance. Our company adopts the excellent hydraulic model with high efficiency and energy saving, so it has the advantages of high efficiency, wide range of performance and so on, and better meets the requirements of users. Vertical multi-stage centrifugal pump is suitable for industrial and urban water supply and drainage. Pressure, long-distance water, heating, bathroom, boiler heating and cooling cycle pressurization, air conditioning and refrigeration systems and water equipment and other occasions.
    DL vertical multi-stage centrifugal pump works and maintenance, when the multi-stage centrifugal pump motor drive shaft on the high-speed rotation of the impeller, filled with the liquid in the impeller under the action of centrifugal force from the impeller center along the blade between the flow channel Thrown around the impeller, because the liquid by the role of the blade, so that the pressure and speed increased at the same time, through the chute of the flow channel was cited to the next level of the impeller, so that once through all the impeller and guide shell, further So that the pressure of the liquid energy increases. After each impeller is superimposed on each step, a certain lift is obtained. Can be applied to industrial and urban water supply and drainage, high-level pressurized water, garden irrigation, heating and water cycle pressurization and equipment supporting multi-stage centrifugal pump is the flow medium (gas and liquid, it can be suspended particles and gas or liquid mixture) from The blade rotates the root (inlet) into the medium, and the medium relies on high-speed rotation of the blade to obtain centrifugal force to produce a high pressure, medium discharge device from the discharge port (outlet). Multi-stage centrifugal pump is the same function of two or more pumps together, the fluid channel structure, the performance of the first stage of the media pressure port and the second level of the import phase, the second level of the media pressure And the third level of the import of the same, so the formation of a multi-stage series of centrifugal pump. The significance of multistage centrifugal pumps is to increase the set pressure.
    DL vertical multi-stage centrifugal pump in the daily use of the process should pay attention to maintaining the use of centrifugal pump products in order to extend its life, the equipment is not prone to failure phenomenon, DL vertical multi-stage centrifugal pump routine maintenance should be done The following points:
    1, should always wipe the centrifugal pump unit and centrifugal pump pipe above the liquid and dust or other dirt, so that the centrifugal pump to keep clean.
    2, should also be regularly replaced centrifugal pump inside the bearing grease, for example, all horizontal centrifugal pump products are usually equipped with sliding bearings, all equipped with sliding bearings centrifugal pump products in use after about 100 hours, Should be replaced with lubricants, after each run 300-500 hours after a rolling bearing for the oil.
    3, if it is sealed single-stage single-suction centrifugal pump products to be checked at any time and adjust the tightness of the filler.
    4, often check and fasten the loose bolts and nuts.
    5, often cleared out of the pool inside the suspended matter, so that the centrifugal pump into the pool clean, to prevent debris blocked the inlet pipe and was sucked into the pump after the damage to the impeller or plug in the pump inside.
