GLB high-efficiency energy-saving self-priming pump

GLB high-efficiency energy-saving self-priming pump

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

GLB series self-priming pump is a new type of high-efficiency and energy-saving excellent product with international advanced level developed by our company on the basis of ordinary self-priming pump, and designed and added intelligent automatic control device. When working, the pump can quickly separate the gas precipitated in the suction pipe or the medium from the conveying medium, and quickly discharge it from the volute of the pump. Sync work.

GLB series high-efficiency energy-saving self-control self-priming pump is our company's active response to and implementation of the national energy conservation and emission reduction policy and industrial policy, and to adapt to market demand, in conjunction with the Chinese Academy of Sciences, Jiangsu University of Science and Technology Institute of Fluid Machinery, Shanghai Water Pump Research Institute and other scientific research departments A new high-efficiency energy-saving new product jointly developed.


2. Application scope of GLB high-efficiency energy-saving self-priming pump

GLB series high-efficiency and energy-saving self-priming pump is an ideal substitute for long-shaft submerged pump, vertical long-shaft pump, submersible sewage pump, ordinary self-priming pump and horizontal centrifugal pump. This product is widely used in steel, chemical, petroleum, electric power , metallurgy, environmental protection, construction, sewage treatment, pharmaceutical, tap water and other areas, due to the unique impeller structure and the self-priming function without drainage, it can transport various concentrations of acid, alkali, salt, sewage and sewage and other media, and according to users Different media and working conditions require special material design, production and manufacturing.

 

3. Features of high-efficiency and energy-saving self-priming pump:

1. The inlet and outlet channels of GLB series self-priming pumps are designed with no bends, which effectively reduces the resistance and loss of the medium during the pumping process to a small extent. Because the impeller and volute are designed with special hydraulic model and combined with advanced production technology, the efficiency of this product can be increased by 20%-30% compared with ordinary self-priming pumps, and the energy saving effect is remarkable.

2. GLB series high-efficiency and energy-saving self-priming pumps are equipped with vertical VI special motors, imported SKF, NSK and other high-quality bearings, and the front and rear end covers are equipped with oil nozzles, which are stable in operation, high in precision, low in noise and long in service life.

3. The impeller, volute and pump shaft of GLB series high-efficiency and energy-saving self-priming pump are made of special wear-resistant stainless alloy material. When the wear-resistant alloy mouth ring is replaced, the pump set can be restored to the parameter value specified by the factory, not only the maintenance cost is low, but also the service life is normally long-shaft submerged pump, vertical long-shaft pump, submersible sewage pump 5-8 times.

4. The seal design of GLB series high-efficiency and energy-saving self-priming pump adopts two series of mechanical seals of cartridge type water cooling and self-cooling. When the water pump pumps the medium without particles at room temperature, the self-cooling machine seal can be selected, which is durable and does not need cooling water configuration. When the water pump is pumping high temperature and mixed with particulate matter, such as metal iron oxide filings, sand and other sewage with harsh working conditions, a container water-cooled mechanical seal can be selected, and the medium sewage does not contact the sealing surface of the mechanical seal to ensure that the mechanical seal is always in good operation. Running in the state, so that the pump set achieves the purpose of long-lasting durability.

5. GLB series high-efficiency and energy-saving self-priming pump is designed with intelligent vacuuming device. The pump group does not need to add water to drain water. After starting the pump, the water can be discharged normally within 0-15 seconds. It can be equipped with an automatic control system according to user requirements, so that the pump group can achieve Local or remote high liquid level automatic pump start, low liquid level automatic pump stop, to achieve the effect of unattended safe and reliable operation.

6. GLB series high-efficiency and energy-saving self-priming pump is designed as a vertical derrick fixed structure, with compact structure, small floor space, low lifting height, no need for large pump room and large lifting equipment for hoisting, simple operation and maintenance, and low cost. According to the user's pump room space position and needs, the suction port of the pump group can be designed to any axial position to meet the needs of different working conditions of the user.

5. Instructions for the use of energy-saving self-priming pumps

1. The pump set should be installed vertically to ensure the smooth operation of the motor and pump shaft.

2. A filter screen must be installed at the lower end of the water inlet pipe of the water pump to prevent large particles and impurities from being sucked into the water pump, entangling or damaging the impeller. When the inlet pipe is connected to the inlet of the pump, the screws must be uniformly stressed to ensure that the inlet pipe does not leak air.

3. When installing the water outlet pipeline, each one-way valve must be installed (prepared by the user). Before starting the pump, the valve must be tightly closed to ensure the water outlet speed of the pump.

4. Before starting the water pump, the cooling water pipe should be connected to ensure that the machine seal cannot be dry-grinded. At the same time, check whether the main shaft of the water pump is flexible, and use the power point method to check the steering of the water pump. After confirming that the steering is correct, the water pump can be started with full pressure.

5. The water outlet pipeline and valve of the pump should be fixed on the support frame (provided by the user). All pipelines other than the pump set must be connected to the pump set without load. All pipeline connection parts must be tight and air-tight, otherwise it will affect the Self-priming function and flow, head.

6. When transporting liquid, the three indicators of flow, lift and suction must be controlled within the range specified by the selected model, otherwise it will cause the motor current to fluctuate and affect the normal operation.

7. The pump is self-priming on the principle of vacuum pump. It is strictly forbidden for users to arbitrarily expand the diameter of the suction pipe during installation, otherwise it will affect the suction speed and cause damage to the motor current overload.

8. The pump is installed on a derrick. If the installation size is required, the user can ask for it from our company after ordering.
