supply High temperature energy-saving centrifugal pump What are the requirements for backfilling after installation? 1. Before backfilling, check that the pump station has not suffered structural damage. If yes, please contact our company as soon as possible and do not dispose of it by yourself! 2. After completing the installation and grouting of the pump station on the cement base plate and reaching the required strength, check that the structure is intact, and then backfill can be carried out. three High temperature energy-saving centrifugal pump Manufacturer Backfilling must be carried out in time after installation to prevent the pump station from floating and toppling, and the FRP material cannot be pulled or squeezed by force. 4.32mm plain soil can also be backfilled with graded sand and gravel, and the particle size of gravel shall not exceed 32mm. When the distance between the pump station barrel and the edge of the foundation pit is less than 1 m but more than 0.5 m, only graded sand and gravel can be used for backfilling, and the gravel particle size shall not exceed 32 mm. When backfilling in winter and rainy days, check whether the backfill materials are stuck together. The backfilling of the foundation pit shall be carried out continuously and completed as soon as possible. During the construction, the ground water shall be prevented from flowing into the foundation pit to avoid slope collapse or damage to the foundation soil. Backfilling shall be carried out in layers. The height difference of each layer shall not exceed 50cm. It shall be compacted with a tamper or manually, and the compaction shall be more than 90%.

Compared with traditional pump stations, High temperature energy-saving centrifugal pump Manufacturer The required installation and commissioning time is greatly reduced. supply High temperature energy-saving centrifugal pump The existing integrated sewage pump station is technically improved, and private customization is provided. In addition, why is the price of qualified fire pump not expensive? The correct fire pump manufacturers, especially those with full qualifications and years of experience, are first of all professional enough in production technology. The working procedures of the system machine, submersible sewage pump and other main control equipment are fed into the PLC machine to achieve automatic operation, so as to reduce the operating workload and reduce unnecessary human damage. The ground occupies only a few square meters, so space is saved. Precautions when selecting comprehensive sewage pump station, remember! The sewage comprehensive pump station has a great impact on sewage treatment, and is a favorite sewage treatment product of many units and enterprises.

High temperature energy-saving centrifugal pump Manufacturer The design principle is: (1) The overall layout should be reasonable, especially for the pump stations that combine irrigation and drainage or self drainage, self diversion and water lifting, as well as the pump stations that combine gates and stations, the layout should be as compact as possible, making full use of buildings for regulation. (2) The selection of pump type shall strive to make the design head of the pump station consistent with the rated head of the pump, and meet the requirements of irrigation and drainage flow. The pump type with advanced technology shall be selected as far as possible to ensure high efficiency of the pump station device and low operation cost. At the same time, the selected pump type should be relatively mature, with certain operation practice, and the test pump type should be avoided as far as possible. (3) The selection of pump type shall fully consider the use and working nature of the integrated pump station. For irrigation and make-up water pump stations with long annual working hours, pumps with wide range, high efficiency and good cavitation performance shall be selected. For those pumping stations focusing on drainage, the pump type with reliable working performance and simple structure shall be selected. (4) The project layout shall adopt positive water inflow as far as possible to ensure that the water inflow condition of each unit is good and the flow pattern is uniform. supply High temperature energy-saving centrifugal pump When lateral water inflow has to be adopted in the project layout, the distance between the lateral water inlet and the pump shall be extended as far as possible in the design, and certain diversion measures shall be taken. (5) The design of the outlet pool should try to avoid sharp bends that cause water impact and backwater. The pressure water tank shall be designed to avoid the increase of energy loss due to the mutual impact of water flow in each outlet pipe. (6) The construction materials available locally shall be used as far as possible. The design shall ensure simple and convenient construction and less project investment.

supply High temperature energy-saving centrifugal pump "Good, fast and economical" Talking about the advantages of prefabricated pump house, High temperature energy-saving centrifugal pump Manufacturer He said, "First of all, the quality of prefabricated concrete components is controllable, the deviation of appearance surface flatness is small, and the concrete strength of prefabricated products can reach C40, which is conducive to improving the instability of concrete quality of traditional cast-in-place structures; Secondly, the construction period is controllable. Prefabricated components are produced in factories, and on-site installation is mechanically hoisted, which is safe and convenient, and can greatly reduce the use of labor. The project duration can be free from the impact of natural weather and other factors; The third is energy conservation and environmental protection. The main body of the project is mostly prefabricated, and a large number of cement, sand and stone and other dust building materials do not need to enter the site. The construction has little impact on the surrounding urban environment. " The prefabricated steel structure building is a form of prefabricated building with high assembly rate, which covers the components of the system such as structure, enclosure, interior decoration and equipment pipeline. It is prefabricated in the factory, and the integrated module is transported to the construction site for assembly and connection to form a complete building. Fabricated steel structure buildings have the advantages of high standardization and high integration, which can greatly reduce the entire construction cycle.

Users also have this problem again. First of all, we should know the composition of the pump station. ad locum, High temperature energy-saving centrifugal pump Manufacturer The pump set is divided into three parts. Main body of pump unit, external control equipment and internal equipment. First, we should select the wall thickness of the pump unit cylinder according to the actual demand. The factors to be considered here include: geology, temperature, working environment of pump unit, altitude, etc. Therefore, the selection of pump unit cylinder wall thickness should be summarized and considered. The wall thickness directly affects the firmness of the pump set. Of course, the selection of internal equipment is also important. During this period, the selection of submersible sewage pump is important. Here, the selection of flow head of submersible sewage pump is important. supply High temperature energy-saving centrifugal pump The flow head of submersible sewage pump shall be selected according to the actual situation. There are many types of submersible sewage pumps. For example, 200 in front of 200WQ300-7-15 refers to the diameter, WQ refers to the pump type, and 300 refers to the flow of 300m ³/ h. 7 refers to the lift of 7m, and 15 refers to the power of this submersible pump of 15KW.
