What is the difference between metering pump and pipeline centrifugal pump
Many customers do not know how to install the varem metering pump and pipeline centrifugal pump. I believe we all know that the pipeline centrifugal pump is the most common pump, which is familiar to the General Hydropower workers. However, the metering pump has been produced and applied on a large scale in China for more than ten years. What is the difference between metering pump and pipeline centrifugal pump? Let's first understand the concepts of the two. Let's talk about the pipeline centrifugal pump first. It is a new pump developed for pipeline pressurization and transportation to solve the problem of low pipeline pressure. It has great advantages over the current application of horizontal centrifugal pump. The advantages of pipeline pump are mainly reflected in the following points:
1. Pipe pump is suitable for high-rise building pressurized water supply, garden sprinkler irrigation, cooling tower water supply, long-distance water supply, air conditioning, refrigeration washing, bathroom cooling, etc. The temperature is below 80 ℃.
2. It is suitable for high temperature hot water pressurized circulation in heating, boiler and other industries. The operating temperature is lower than 150 ℃.
3. It is suitable for conveying corrosive medium in the process of food, pharmaceutical, wine making, chemical industry and other industries, and the service temperature is below 80 ℃.
4. It is suitable for conveying non corrosive liquid, methane or other industrial places with class I fixed equipment in coal mine, class IIa and IIB factory, T1, T2, T3 and T4 temperature group and explosive mixture. The use temperature is lower than 80 ℃.
5. Pipeline pump is suitable for conveying corrosive liquid in chemical, pharmaceutical, petroleum, food, national defense and other industries, as well as industrial places such as methane or underground fixed equipment class I, factory class IIa, class IIB, temperature group T1, T2, T3, T4, explosive mixture, etc. The use temperature is lower than 150 ℃.

1. Preparation before installation of pipeline centrifugal pump 1. Prepare installation tools and lifting equipment; 2. Check whether the parts of zilmet pump unit are loose and damaged during transportation; 3. Check whether the foundation is flat. Precautions for installation of pipeline centrifugal pump: 1. Flexible joint 2. Elbow 3. Gate valve 4. Straight pipe (pressure pipe) 5. Pump 6. Base seven. Support structure 8. Shock absorber 2. Installation sequence of pipeline centrifugal pump 1. When the unit is transported to the site, the water pump and motor have been calibrated by the auxiliary personnel of the base, so the installation is very convenient. 2. Place the base on the foundation, place the wedge iron pad near the anchor bolt, raise the base 20 ~ 40 mm after leveling to fill the cement slurry; 3. Check the levelness of the base with the level meter, fill the base with the cement slurry after leveling, and check the levelness after the cement is dry; 4. When the power of the unit is high, the pump, motor and base can be packed separately to facilitate transportation. At this time, the user needs to install and calibrate the pump unit. The methods are as follows: a . clean the dirt on the supporting surface of the base, the water pump foot and the motor foot plane, and put the water pump and the motor on the base; B. adjust the level of the pump shaft, and after leveling, fix the pump on the base with bolts to prevent walking; C. lift the motor to make the pump coupling and the motor coupling cooperate, and lower the motor to the corresponding position on the base; D. adjust the gap between the two couplings to about 5mm, and correct Whether the axes of motor shaft and pump shaft coincide. The method is to place the ruler on the coupling, and the outer circles of the two couplings should be flush with the ruler. If it does not coincide, adjust the relative position of motor or pump, or adjust it with thin sheet iron; e. in order to check the installation accuracy, measure the clearance between two coupling planes at several different positions on the coupling circumference with a feeler gauge. Within one week, the difference between the maximum clearance and the minimum clearance on the plane of the coupling shall not exceed 0.3mm, and the difference between the upper and lower or left and right center lines at both ends shall not exceed 0.1mm.. 5. When the unit has no base, it needs to be directly installed on the foundation. The method is similar to 4, but more attention should be paid to calibration. 3、 Precautions for installation of pipeline centrifugal pump 1. During the installation, the pipeline should not be pressed on the pump, otherwise it is easy to damage the pump; 2. During the installation, the foundation bolts must be tightened, and the unit must be checked regularly to prevent loosening, so as to avoid the huge vibration that affects the pump performance during the start-up and operation of the pump; 3. Before the installation of the pump, it is necessary to carefully check whether there are any hard objects (such as stone and iron sand) that affect the operation of the pump, so as to avoid damaging the flow passage parts during the operation of the pump; 4 In order to facilitate maintenance and safe use, regulating valves should be installed on the inlet and outlet pipes of the pump, and pressure gauges should be installed on the inlet and outlet flanges of the pump. For high lift pump, in order to prevent water hammer, a check valve should be installed in front of the outlet gate valve to deal with sudden power failure and other power failure accidents, so as to ensure the operation of the pump under the best working conditions and prolong the service life of the pump; 5. When the pump is used in suction occasions, it should be equipped with bottom valve, the inlet pipe should not have too many elbows, and there should be no water leakage or air leakage, so as not to affect the suction performance of the pump; 6 In order to prevent impurities from entering the pump and blocking the flow channel will affect the performance, the filter should be installed before the entrance of the varem pump; 7. Before the pipeline installation, the rotor parts of the pump should be rotated without friction sound or jam, otherwise the pump should be disassembled to check the cause; Shanghai Longya pump valve brand service commitment: repair, replace and return the defective products within the warranty period; all quality complaints A response should be received within 24 hours. Service personnel shall be dispatched to leave the site without troubleshooting or making conclusions. The accessories produced by our factory are original ones.

Let's talk about the metering pump, which is generally used to transport those corrosive liquids in the industry. In the era of rapid development, now there are many industries rising, such as pharmaceutical, food and beverage, petrochemical and chemical industry, etc. in the process of production, there are often strong corrosive acid liquid. At this time, we need to use mechanical diaphragm metering pump, which is also the main application of mechanical diaphragm metering pump in the industry. Nowadays, metering pump is mostly used in the industry, because of its stability and controllability, it is highly praised in the industry, so it has a good prospect in the market. The installation of metering pump is similar to that of pipeline centrifugal pump. The hydraulic end of metering pump includes pump head, diaphragm, valve, back plate and mounting bolt. Just install the fixing bolts and the inlet and outlet pipes.
