    Maintenance method of condensing boiler
    1、 Before starting the condensing boiler, it is necessary to check whether the pressure gauge and temperature gauge display normally. If any problem is found, it needs to be repaired in time. This must not be ignored. Of course, it is necessary to carefully check whether there is water leakage in the pipeline and whether there is abnormal noise in each water pump. If there is any problem, At this time, the condensing boiler cannot be started. 2、 Before starting up, great attention should also be paid to the maintenance of the equipment. For example, it is necessary to check whether the circulating water in the make-up water tank and the primary system of the boiler is sufficient. If there is a lack or accidentally discharged after heating, it is necessary to contact the after-sale

    Classification and selection of sewage lift pumps?
    Sewage lift pump is a pump product with simple installation and convenient disassembly. It is generally suitable for all kinds of industrial plants or sewage treatment projects. No matter where it is used, the selection of sewage lift pump is a very important link. If it is wrong, it will be a waste of money. The sewage lift pump is mainly used for sewage discharge in places without gravity drainage. First of all, we have to have drainage needs before we use it. Because the municipal sewage pipe does not sink (the municipal sewage pipe refers to the rainwater and sewage pipe under the municipal road, which is generally arranged under the non motor vehicle lane and carriageway on the northwest side of the road, and the soil covering depth is 0.6-0.7m), Therefore, all drainage point

    What factors affect the use of all welded ball valve?
    As we all know, ball valves are widely used in chemical, petroleum, metallurgy and other fields. The inner wall of the popular all welded ball valve is extremely smooth. In the process of ball valve conveying medium, the friction between the inner wall of the ball valve and the medium is very small, and the medium can pass unimpeded. However, the operation of all welded ball valve will be affected by some factors. 1、 Influence of sealing materials In actual working conditions, all welded ball valves generally use various gases as media: such as natural gas, gas, gas, chemical industry, heating, heating, etc. the temperature of these media is generally between - 20 ℃ - 150 ℃, and the nominal pressure is PN16-25 pressure. The soft seal can meet the requirements, but the quali

    With the rise of sina tide of scientific and technological revolution, screw pump manufacturing highlights the style of enterprises
    In recent years, with the rapid development of scientific and technological revolution, traditional industries and traditional manufacturing methods are facing great challenges, and the development of many traditional industries is in trouble. Relying on the imitation of foreign production mode is not a long-term solution. Only by truly improving the quality of products, doing a good job in the product market and improving their own scientific and technological innovation achievements can we change the current dilemma of social development. The screw sealing line in contact with the stator and rotor in the screw pump completely separates the income chamber from the discharge chamber, so that the screw pump has the isolation function of the valve, and can realize the multiphase mix

    Ceramic valve is based on scientific research and innovation to escort the green development of chemical industry
       With the higher and higher degree of social and economic development, people have higher and higher requirements for the construction of ecological civilization. It is people's common expectation to realize the green development of all walks of life. If the production equipment is backward and the product R & D ability is weak, it is obviously unrealistic to achieve the goal of green development. In the process of chemical industry development, it is natural to be inseparable from various valves. Traditional metal valves are more obvious in the process of use, that is, poor corrosion resistance, poor durability and prone to "running and dripping" and other problems. These shortcomings not only affect the continuity of chemical equipment work, but also may have an i

    What are the reasons for the vibration of stainless steel diaphragm pump?
    Even if the water pump manufacturer uses high-quality raw materials and processes to manufacture the water pump, there will still be some abnormalities in the long-term use of the stainless steel diaphragm pump. Among them, the vibration of water pump is common, and there are many reasons for the vibration of unit and pump house building. Specifically, the following reasons will lead to the vibration of stainless steel diaphragm pump: 1、Electrical reasons The motor is the main device in the stainless steel diaphragm pump unit. If the magnetic force inside the motor is unbalanced and out of balance with other electrical systems, it will cause vibration and noise. For example, when the asynchronous motor is running, the radial alternating magnetic tension of the stator and ro
