supply Non negative pressure integrated pump set How to choose? Non negative pressure integrated pump set Manufacturer The main equipment in the pump station selected according to the input and output are: various controllable valves, pump sets, grid systems, water level gauges, flow meters, etc. According to the requirements of the system and the different control methods adopted, as well as the nature, parameters and characteristics of the input and output signals, the appropriate PLC system can be flexibly selected. Select according to the storage capacity Calculate the actual capacity demand of the storage according to the number of nodes required for programming. The PLC control system used in the current pump station is selected according to the communication requirements, which is generally divided into equipment unit layer, pump station layer, dispatching layer, etc. Layers directly need to transmit various parameter information, so we should select the appropriate PLC equipment according to the field needs, such as network, expansion, off the shelf bus connection, investment and our own equipment.

Compared with traditional pump stations, Non negative pressure integrated pump set Manufacturer The required installation and commissioning time is greatly reduced. supply Non negative pressure integrated pump set 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.

Non negative pressure integrated pump set Manufacturer Introduce the basic structure of the integrated pump station: 1 supply Non negative pressure integrated pump set The GRP glass fiber reinforced plastic cylinder is made of GRP glass fiber reinforced plastic, and the process is continuous mechanical winding. It is characterized by firmness, durability, non leakage, corrosion resistance, and a service life of 50 years. 2. The base is made of GRP glass fiber reinforced plastic, and the process is molding. It is characterized by anti clogging, anti floating and anti sinking, and its service life can also reach 50 years. 3. The top cover is generally made of embossed aluminum plate, or stainless steel, glass fiber reinforced plastic and other materials, which is used for personnel access. 4. Handrails are made of 304 stainless steel or 316 stainless steel. 5. The control cabinet can be made of 304 stainless steel or 316 stainless steel, which is the core of intelligent control. 6. The flange is made of 304 stainless steel. 7. Check valve, with various stainless steel materials, such as 304, 201, 316, etc. 8. Gate valve is made of 304 stainless steel, or 201, 316, etc. 9. The grating support is made of 304 stainless steel. Similarly, 316 stainless steel can also be selected.

supply Non negative pressure integrated pump set In the design, there is no such statement as main pump and standby pump. Our statement is that one is in use and one is standby or two is in use and one is standby. They are standby for each other and used in turn. When one is running, the other is the standby pump. Non negative pressure integrated pump set Manufacturer The first reason for setting a standby pump is to ensure that when the pump is damaged or overhauled, there is still a pump that can work, rather than that we can't use water as long as the pump is broken or regularly overhauled. The second is to let the pump take turns to rest after working for a period of time. To prevent long-term continuous operation from affecting the normal service life of the pump.

supply Non negative pressure integrated pump set 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 Non negative pressure integrated pump set 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%.

Users also have this problem again. First of all, we should know the composition of the pump station. ad locum, Non negative pressure integrated pump set 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 Non negative pressure integrated pump set 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.
