GLB high-efficiency energy-saving unsealed self controlled self-priming pump

1、 Working principle of GLB high-efficiency energy-saving vertical self-priming pump

GLB energy-saving self-priming pump is a new type of high-efficiency and energy-saving special product developed by our company on the basis of optimizing and upgrading ordinary self-priming pumps, and designing and adding intelligent automatic control devices with international advanced level. When working, the water pump can quickly separate the gas released from the suction pipe or medium from the conveying medium, and quickly discharge it from the volute of the water pump. With the help of an intelligent device, the water pump can immediately start and discharge water, enabling the water pump to achieve synchronous operation of exhaust and discharge.

GLB series high-efficiency energy-saving automatic self-priming pump is a new type of high-efficiency energy-saving new product that our company actively responds to and implements the national energy conservation and emission reduction guidelines and industrial policies, adapts to market demand, and cooperates with scientific research departments such as the Chinese Academy of Sciences, the Fluid Machinery Research Institute of Jiangsu University of Technology, and the Shanghai Pump Research Institute.

2、 GLB high-efficiency energy-saving vertical self-priming pump application scope

GLB seriesEfficient and energy-saving self-priming pumpIt is an ideal replacement product for long shaft submersible pumps, vertical long shaft pumps, submersible sewage pumps, ordinary self-priming pumps, and horizontal centrifugal pumps. This product is widely used in areas such as steel, chemical, petroleum, power, metallurgy, environmental protection, construction, sewage treatment, pharmaceuticals, and tap water. Due to its unique impeller structure and self-priming function without drainage, it can transport various concentrations of acids, alkalis, salts, sewage, and other media, and is designed, produced, and manufactured with special materials according to different media and working conditions of users.

3、 Vertical self-priming pump product features:

1. The GLB series self-priming pump adopts a non curved design for the inlet and outlet channels, effectively reducing the resistance and loss of the medium during the pumping process to the minimum extent. Due to the special hydraulic model design of the impeller and volute, combined with advanced production technology, the efficiency of this product can be increased by 20% -30% compared to ordinary self-priming pumps, and the energy-saving effect is significant.

2. The GLB series high-efficiency energy-saving self-priming pump is equipped with a vertical VI special motor, using imported high-quality bearings such as SKF and NSK, and both the front and rear end caps are equipped with oil nozzles, ensuring smooth operation, high precision, low noise, and long service life.

3. The GLB series high-efficiency and energy-saving self-priming pump impeller, volute, and pump shaft are made of special wear-resistant stainless alloy materials cast and processed. The impeller and volute are designed and installed with detachable wear-resistant alloy mouth rings. When the operating efficiency of the pump unit decreases, simply replacing the wear-resistant alloy mouth ring can restore the pump unit to the factory specified parameter values. Not only is the maintenance cost low, but the service life is also 5-8 times that of long shaft submersible pumps, vertical long shaft pumps, and submersible pumps under normal circumstances.

4. The GLB series high-efficiency energy-saving self-priming pump adopts two major series of mechanical seals: containerized water-cooled and self cooled. When the water pump pumps non granular media at room temperature, a containerized self cooling machine seal can be used, which is durable and does not require cooling water configuration. When the water pump pumps high temperature and mixed with particles such as metal oxide iron shavings, sand particles, and other harsh working conditions in sewage, a containerized water-cooled mechanical seal can be used. The medium sewage does not contact the sealing surface of the mechanical seal, ensuring that the mechanical seal is always in good operating condition, so that the pump set can achieve the purpose of durability.

5. The GLB series high-efficiency and energy-saving self-priming pump is designed with an intelligent vacuum pumping device. The pump set does not require water drainage, and water can be discharged normally within 0-15 seconds after starting the pump. It can also be equipped with an automatic control system according to user requirements, which can enable the pump set to automatically start at high liquid levels locally or remotely, and automatically stop at low liquid levels, achieving the effect of unmanned safe and reliable operation.

6. The GLB series high-efficiency energy-saving self-priming pump is designed as a vertical derrick type fixed structure, which is compact in structure, occupies a small area, and has a low lifting height. It does not require a large pump room or large lifting equipment for lifting, and its operation and maintenance are simple, convenient, and cost-effective. The pump set suction port can be designed at any axial position according to the user's pump room space location and needs to meet the different working conditions of the user.
