II structural characteristics

1、 The detachable structure of * enables it to have the following detachable functions:

1. The motor and some detachable functions of AYSLB pump: The motor used in the detachable pump has a high degree of universality. If it is necessary to replace the same model of motor or water pump, simply disassemble and remove the clamp type coupling, and then remove the connecting screws between the motor and the bracket to remove the motor or water pump for replacement.

2. The mechanical seal replacement part of AYSLB pump has a detachable function: When replacing the mechanical seal of the detachable pump, the motor does not need to be disassembled, only the clamp type coupling needs to be disassembled and removed, and then the seal cover can be opened to remove the mechanical seal for replacement.

2、 Compact structure and beautiful appearance: This series of pumps is a detachable structure that integrates the machine and pump, with a beautiful appearance. Its vertical structure determines a small installation area, which not only reduces the pump room area, improves the area and space, but also greatly saves infrastructure investment. If IP54 outdoor motors are used, it can save more investment in pump room infrastructure.

3、 Easy installation: The inlet and outlet flanges of the pump are the same as the standard valve flanges and located on the same centerline, with a low center, making it convenient for pipeline layout. The pump room design is also more reasonable and practical.

4、 Convenient disassembly function, easy maintenance, and low maintenance cost:

1. The AYSLB pump adopts a sealed detachable structure. When repairing the mechanical seal of the pump, there is no need to disassemble the motor and inlet and outlet pipelines. Only the clamp type coupling needs to be disassembled and removed, and then the seal cover on the pump cover needs to be disassembled and removed to replace the mechanical seal. Maintenance is very convenient and labor-saving.

5、 Stable and Long Service Life: The AYSLB pump adopts a specially designed clamp type coupling, which has smooth operation, low noise, high component concentricity, and increases the smoothness of operation and long service life.

6、 High efficiency and good performance: The impeller adopts a new double suction structure hydraulic model design and manufacturing, eliminating the shortcomings of the original vertical pump with large radial tension. The impeller is always in a suspended state during operation, with high efficiency and good performance. At the same time, it also reduces the flat wear of graphite bearings, thereby improving the service life of the water pump and reducing operating costs.

7、 Innovative design, structure *, and cost savings in operation and management: adopting a brand new internally placed water lubricated bearing, utilizing high-pressure return fluid from the water pump outlet to enter the pump base through the return pipe for self lubrication, without the need for lubricating oil, thus not polluting the conveying medium and eliminating the trouble of regular oil injection. We use imported graphite impregnated resin bearings with nickel based alloy shaft sleeves and thrust discs, which have the characteristics of high wear resistance, low friction coefficient, anti-aging, and anti silt. In addition, the bearings are equipped with thrust discs that can withstand the self weight thrust of the pump impeller.

8、 Reliable and leak free sealing: The shaft seal adopts mechanical sealing, and the sealing friction pair adopts graphite to silicon carbide or silicon carbide to hard alloy, which is wear-resistant, leak free, and has a long service life.

9、 Standardization, serialization, and high universality of components: For example, if the motor adopts Y or Y2 series B5 type, it belongs to the standard universal motor, which is easy and fast to maintain and upkeep.

10、 This series of detachable vertical single-stage double suction pumps belongs to the new generation of detachable vertical pumps developed by our company. Compared with other manufacturers' detachable pumps, the SLB pump has a * * feature: the total height of the SLB pump is greatly reduced without affecting the function of disassembling the seal. Because only the mechanical seal is disassembled, the connection bracket between the pump and the motor is particularly short, and the stability is stronger. Moreover, when replacing the mechanical seal of the sealed detachable pump, no matter how high the power of the water pump is, even if there is only one maintenance worker on site, as long as he can handle the half piece coupling, he can independently complete the maintenance work of the seal and achieve the function of disassembling and repairing.

II Product Overview

AYWQS energy-saving double submersible sewage pump is a brand new pump product developed by our company based on market demand. *There is a historical gap in this type of pump in China, and a utility model (No. 2009) has been developed

10196735.5), this pump * solves the disadvantages of high axial tension of single suction submersible electric pumps and easy water leakage when using mechanical seals in high head situations.

The AYWQS energy-saving double suction submersible sewage pump adopts the commonly used pump's edge water outlet and flange installation structure, which can be installed either by moving or fixed with guide rails. Easy to install, maintain and use, energy-saving, durable, anti blocking, automatic installation and self

Features such as dynamic control.

Due to the use of a double suction and double flow channel structure, water enters the pump from both ends of the impeller and flows out in the middle during actual operation. The inlet of the water pump is divided into upper and lower parts, and both draw water from the bottom, with a low suction level. Because the pump absorbs water from both ends, and the isolated oil chamber between the pump and the motor is located at the suction port, the oil chamber is always in a negative pressure state during operation. Compared with the single suction structure mechanical seal, it is less likely to leak or be damaged. Since the pump absorbs water from both ends simultaneously, the motor has no axial tension, and the dual channel structure reduces radial force, thereby extending its service life and achieving durability, stability, and practicality.

The hydraulic performance of the pump is advanced and mature. After testing, all performance indicators of the product have greatly exceeded the relevant standard JB/T5118-2001, and a high standard enterprise standard filing has been established (standard number: Q/TNTP001-2010). After being introduced to the market, the product has been well received and praised by a large number of users for its * effectiveness, reliable performance, and stable quality.

This pump is divided into two series: clean water and sewage, and these two series are further divided into three categories: ordinary type, with external circulation cooling water type, and automatic mixing type.
