With the improvement of people's living standard and energy consumption, energy power system has drawn more and more attention. The large-capacity HVAC drainage and drainage equipment has been widely used in living facilities and recognized by the market. Pipeline electric pump is also one of them.
Shielded electric pump from the market has been more than 30 years of history, it is used in the north as a heating alternative to other heating equipment to play a very good effect, by the people.
The advantages of shielded electric pump is obvious, it not only low noise, no leakage, stable operation, and long service life, maintenance-free. However, it brings people to enjoy the same time we have to see it there are still some drawbacks: due to the shielded motor, shielding sleeve loss is large, so affect the efficiency of the motor, so there are shortcomings in energy conservation. At present, some of the three manufacturers tackle the energy-saving technologies of shielded electric pumps through long-term exploration, development and application of scientific concepts and do effective and stable tests on energy-saving of electric motors so as to solve the problems of large losses and high efficiency in the shortest time Low-level questions.
Furthermore, due to the fact that modern humans attach great importance to resources, environment and sustainable development, a series of requirements have been put forward for such issues as energy saving and environmental protection of cogeneration and central heating, Inside and outside for further scientific improvement, improve and completely solve the problem of excessive energy consumption.
Shanghai Huang Can Co., Ltd. G system pipeline shielded pump, in the design and development of innovative energy-saving aspects, and how to control product quality has the following characteristics, may give some reference to peers.
1. For the pressurized parts in the assembly, must be strictly through the water (gas) pressure test, such as bearings, pump body, the base are playing 1.5MPA / 3MIN without leakage, after passing the test in order to continue next process installation. Especially the base, because the base processing, not for parts of the hydraulic test, hydraulic assembly test after a short period of time is difficult to find problems, therefore, after long-term use of the pump, found that the screw seat slightly Stomata lead to micro-leakage, such as the problem, we do a hydraulic test in a single part will be found, will not flow into the next process.
2. The balance of the impeller on the pump vibration and noise is very critical, and some enterprises only balance the impeller, in order to improve product quality, we take more positive balance of the impeller. The unbalanced single-sided weight tolerance must be controlled at 2 grams or less, so as to ensure that the impeller balance rotation, but also reduces the impeller due to imbalance caused by vibration, while reducing noise, reducing radial force, extending the bearing Service life. In addition, the imbalance of the impeller to heavy, we use a smooth transition of the impeller surface turning to weight removal, the purpose is to reduce the vortex, reduce hydraulic losses and improve water efficiency.
3. We not only consider the internal quality of shielded electric pump, but also for the external structure of the pump has been improved, the original installation of the pump at the bottom of the through-hole is circular, so cement stool mounting holes play a slight deviation, It is difficult to align the screw with the through hole. This has brought inconvenience to the installation, we have improved this, with a half circle instead of circular, so there is left and right clearance, no worries to install it.
4. Electric pump medium temperature less than or equal to 95 degrees, the motor winding with H-class magnet wire, it can guarantee a high temperature of 220 degrees.
5. Due to the low electromagnetic loss of cold-rolled silicon steel sheet, high motor efficiency and low electromagnetic noise, we use cold-rolled silicon steel sheet for the stator and rotor iron core.
6. Graphite bearings are silent pump design of the main components, but also control the heart of the rotating part of the bearing is related to the quality and reliability of the use of pump life. The graphite bearing we choose is epoxy-impregnated M104H type, which is proved by practice. The hardness of graphite bearing is hard and wear resistance is strong.
7. For the rotor we use dynamic balance correction, under strict process control, we control the rotor unbalance weight below 1.5 grams to ensure that the pump balance and reduce the amount of wear and tear bearing wear and tear to extend the service life of the pump.
8. Must have a high-quality inspection team, for finishing the size of each channel, only the mouth of the dimensional tolerances and geometric tolerances are strictly related to the control within the allowable tolerance to self-test, the first inspection, the entire inspection of a set of tests System to test norms to ensure the assembly of the pump concentricity, verticality, low noise and other installation requirements to ensure the quality of the product installation.
9. In order to prevent the impeller from corroding, we have plated the surface of the impeller at the front and the back of the impeller to keep the impeller in good working condition all the time.
10. We have a complete set of pump performance testing equipment, the pump before leaving the factory, each must conduct a performance test for the test failed products will not be shipped, which is responsible for the majority of users, but also for our corporate reputation. Adopted a system of shielded pump technology strictly and scientifically to control and check, shielded pump in use when the safety, durability and reliability have been fully guaranteed, and further enhance its use life.
