Attend the IE EXPO Guangzhou "China Environmental Protection EXPO Guangzhou" (IE EXPO Guangzhou) and IFAT global series exhibition share the resources of global exhibitors and visitors, providing a high-quality professional platform for the high-speed development of the environmental protection industry, better looking for new technology, new products, exchange of experience, discuss the mutual cooperation between the industries.   The core of the 6th IE EXPO Guangzhou in 2020 is "to innovate the service industry and comprehensively boost the development". The exhibition areas include water and sewage treatment, water supply and drainage, solid waste treatment, air treatment, site restoration, and environmental monitoring technology and equipment.   Zigong Pump & Valve, as a leading manufacturer of  axial flow pump , received much attention at the meeting, and the axial flow pump with a diameter of 1500mm was praised among peers. At the same time, the latest...

 What are the specifications and models of the  self-priming pump ? They are mainly divided into a civil self-priming pump for deep well water (self-priming height is 30 meters), gas-liquid foam self-priming pump containing gas foam, and the more common corrosion resistant self-priming pump in the specifications and models of the self-priming pump. 1. The specifications and models of self-priming pumps that can absorb deep well water are suitable for use in environments with a wellhead diameter of more than 100mm. The self-priming height can reach 30 meters, but the flow range of this series of self-priming pumps is small. The flow rate is the only 2.7m3/h, and the head can be Reach 100 meters. The self-priming pump that can absorb deep well water is only suitable for transporting clean water in an environment with large sand content. It is not easy to use otherwise the rubber sleeve is easy to wear and damage, and it is not suitable for transporting corrosive liquids. 2. The ...

 Any product needs maintenance during use, otherwise, the service life will be greatly reduced. The same is true for multistage pumps, so how do we maintain  multistage pumps ? 1. Check for looseness in the pipes and joints of the stainless steel multistage centrifugal pump. Turn the stainless steel pump by hand to see if the stainless steel pump is flexible. 2. Add bearing lubricating oil to the bearing body, observe that the oil level should be at the centerline of the oil mark, and the lubricating oil should be replaced or replenished in time. 3. Unscrew the water diversion screw plug of the pump body of the stainless steel multistage pump, and pour water diversion (or slurry). 4. Close the gate valve, outlet pressure gauge, and inlet vacuum gauge of the outlet pipe. 5. Jog the motor to see if the rotation of the motor is correct. 6. Turn on the motor. When the stainless steel horizontal multistage pump is running normally, open the outlet pressure gauge and the inlet vacuu...

  Multistage pumps  are mainly used for high-temperature condensate recovery, boiler water supply, and water supply and drainage for factories, cities, and mines. Multistage pumps are horizontal, multistage segmented, single-suction pumps, used to transport clear water without solid particles or liquids with physical and chemical properties similar to clear water. The head is 25-200 meters, and the head can be increased or decreased according to user needs The number of pump sections and maintain excellent sealing performance. Multistage pump composition The multistage pump is mainly composed of four parts: stator, rotor, bearing, and shaft seal: 1. The stator part of the multistage pump is mainly composed of the suction section, the middle section, the discharge section, and the guide vane. There are tension bolts to clamp each section to form a working room. The D-type pump generally sucks in horizontally and discharges vertically upward; when u...

 3. Oil cooling inside the machine and cooling water outside the equipment QY oil-filled  submersible sewage pumps  use this type of refrigeration method. The internal organs of the oil-filled motor are filled with insulating grease. Its motor stator core, motor stator winding, motor rotor core and rotor winding (motor rotor guide bar and rotor end ring), and other components are all immersed in oil in. The heat generated by the stator iron loss of the motor, the resistance loss of the stator slot winding of the motor, and a part of the resistance loss of the top winding is immediately sent to the river water flowing through the surface of the casing according to the stator core of the motor. Part of the heat generated by the resistance loss of the motor rotor winding and the loss of the rotor iron is sent to the motor stator immediately through the hydraulic oil in the magnetic density, and sent to the river outside the motor through the shell; the other part is sent to ...

 Well  submersible pumps  are divided into four types according to their internal structure: water injection, oil-filled, shielded-off, and dry-type. The material on the inner wall of the motor is divided into three types: water, oil, and gas. The shielded-off motor is filled with Epoxy resin or plastic filler, the external material of the motor is river water. The cooling methods of submersible pumps of various structures are different and can be divided into four basic types. 1. Double water cooling method inside and outside the motor The inner wall of the water injection submersible sewage pump is injected with water. The motor stator core, motor stator winding, motor rotor core, and rotor winding (motor rotor guide bar and rotor end ring) are all immersed in water and immediately cooled by the body water. The heat generated by the stator iron loss of the motor, the resistance loss of the stator slot winding of the motor, and a part of the resistance loss of the t...
