AS SERIES STRUCTURE

●The appearance of the AS series double suction water pump is designed by a professional appearance design company in accordance with modern industrial aesthetics requirements, and the overall appearance is elegant. At the same time, according to

The CAE mechanical simulation report shows partial thickening, which increases the safety and reliability of the pump casing.

●The AS high-efficiency energy-saving pump retains the characteristics of a split pump that can be repaired by directly opening the pump cover and the automatic balance of axial force of the double suction impeller. At the same time, the inlet and outlet are set on the same horizontal axis, which is conducive to engineering installation and pipeline design and layout.

●The shaft of the AS high-efficiency energy-saving pump adopts a double axis extension structure, and there is no distinction between the clockwise and counterclockwise axes; Except for the impeller keyway, no other keyways, snap ring grooves, or steps are set in the middle section of the shaft, and it is one level thicker than similar pump shafts, enhancing the life and strength of the shaft.

●The impeller and double suction sealing ring of the AS series double suction water pump adopt our company's patent number ZL 2013 2 0499236.5 double-sided seal, which increases the leakage path and reduces the leakage amount. At the same time, the speed carried by the leakage water can be utilized, improving efficiency.

●The impeller and impeller guard of the AS high-efficiency energy-saving pump are sealed with a copper gasket, which is durable and extends its service life; Add a short shaft sleeve and O-ring behind the impeller stopper to achieve dual axial and radial sealing.

Place the outer snap ring on the positioning slot 1 when installing the mechanical seal, making the installation of the mechanical seal more convenient; After the installation of the machine seal, retract the outer snap ring onto slot 2, so that the flushing and cooling water of the machine seal can better flush and cool it.

●The shaft seal structure of the AS series double suction water pump is reliable and universal. It can adopt a containerized box structure and is also suitable for packing or mechanical sealing, fully considering universality and interchangeability. It fully considers the excellent operating environment and service life requirements of various shaft seals.

●The bearing body of the AS high-efficiency energy-saving pump adopts a cylindrical structure, ensuring stable and reliable operation; Can be equipped with temperature measuring elements, vibration measuring elements, constant position oil cups, etc. simultaneously; In terms of lubricant selection, both grease lubrication and thin oil lubrication can be used; In terms of cooling, it can be achieved through circulating water cooling or free air cooling by heat sinks.

●The bearing body seal of the AS high-efficiency energy-saving pump adopts a dual seal of threaded seal and skeleton oil seal. After experimental verification, the protection level is equivalent to the IP55 of the motor, and it can operate outdoors.

●The bearing and shaft sleeve of the AS high-efficiency energy-saving pump adopt a clearance fit. When the shaft sleeve presses the bearing, the O-ring is compressed and deformed towards the outer ring, resulting in a tight fit throughout the structure; After loosening the shaft sleeve nut, the elastic force of the O-ring bounces the shaft sleeve open. No need for specialized disassembly tools and space, saving workload.

●The bearing bracket of the AS series double suction water pump adopts our company's patent number ZL 2013 2 0373133.4 oblique overflow groove. When debris blocks the drainage hole, water can still flow out of the overflow groove, overcoming the disadvantage of filling water soaking the bearing and achieving the purpose of protecting the bearing.

●The bearing body of the AS high-efficiency energy-saving pump is fixed on the pump body through the bearing body pressure block, which is easy to disassemble, has strong interchangeability, and is stable and reliable.

●The bearing body and shaft seal of the AS high-efficiency energy-saving pump are equipped with a beautiful and generous protective cover to ensure the safety of on-site operators and inspectors.

●The axial direction of the AS series double suction water pump is locked and fixed with round nuts and stop washers to prevent axial displacement and loosening of sleeve components; It can also prevent the pump from loosening the rotor components due to short-term reversal.
