Non negative pressure integrated pump set manufactor It is of great significance to use light weight and small volume FRP materials, adopt integrated structural design, and occupy a small area, effectively relieving the current situation of land resource tension. During the design and development of the pump station, advanced innovative ideas were introduced to provide people with high-quality life services. large Non negative pressure integrated pump set On the premise of liberating human resources, it has realized the treatment of domestic sewage and rainwater, and the sewage treatment effect is also very good. On the premise of ensuring the functional requirements of the pump station, the impact of the construction and use of the pump station on the surrounding environment is minimized, which effectively promotes the promotion and application of the pump station.

large Non negative pressure integrated pump set While making outstanding contributions to sewage collection and treatment and flood control and waterlogging drainage, it also has many defects, such as large floor area, high cost, and easy to produce methane volatilization to pollute the environment. But with the upgrading of technology, Non negative pressure integrated pump set manufactor According to the market demand, we have developed and produced an integrated prefabricated pump station with more optimized performance, which has solved many disadvantages of the concrete pump station and replaced the traditional concrete pump station as the current mainstream pump station.

Non negative pressure integrated pump set manufactor General provisions: equipment discharging heat, steam or harmful substances, large Non negative pressure integrated pump set Local exhaust should be adopted. When local ventilation can not be used or local ventilation can not meet the health requirements, it shall be supplemented with all-round ventilation or adopt all-round ventilation. The air distribution design shall be optimized according to the characteristics and changes of pollutants, and the normal operation of local exhaust system shall not be damaged. At the same time, when releasing waste heat, moisture and harmful substances, the ventilation volume in all aspects shall be determined according to the large air volume required. When the quantity of harmful substances cannot be determined, the ventilation volume in all aspects can be determined according to the ventilation frequency. All kinds of pump rooms in the domestic sewage treatment station should adopt natural ventilation. When mechanical ventilation is adopted, indoor air should not be recycled. All pump rooms in the oily sewage treatment station should adopt natural ventilation. When mechanical ventilation is adopted, indoor air should not be recycled, and the ventilator and motor should be explosion-proof and directly connected.

large 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 manufactor 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.

Non negative pressure integrated pump set manufactor 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. large Non negative pressure integrated pump set 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.
