CYZ self-priming centrifugal oil pump working principle:
1. The installation height of the pump shall not exceed the allowable suction height.
2, the pump has no safety valve, it is recommended to set a safety valve in the oil discharge pipeline, to ensure the safe operation of the system.
3, CYZ self-priming pump steering provisions: from the pump end to the motor, the direction of rotation is counterclockwise.
4, the pump has no safety valve, it is recommended to set a safety valve in the oil discharge pipeline, to ensure the safe operation of the system. The formation of vacuum, the liquid suction, the tooth valley brought to the oil chamber, and the volume of the oil chamber, because of the meshing teeth into the meshing and big and small, the oil is compressed and discharged, so as to achieve the purpose of conveying oil.
5, the steering provisions: from the pump end to the motor, the direction of rotation is counterclockwise.
6. The installation height of CYZ self-priming centrifugal pump shall not exceed the allowable suction height
7, the unit should be installed on the level of cement foundation, fixed with foot bolts. CYZ self-priming centrifugal pump is a positive displacement pump. The main and passive gears, the pump body and the left and right pump cover form two closed Spaces of oil inlet and oil outlet. When the gear rotates, the volume of the oil inlet cavity changes from small to large due to the continuous disengagement of the meshing teeth. This series pump is mainly composed of: left and right pump cover, pump body, active and passive gear shaft, shaft sleeve, oil seal and other parts.
CYZ self-priming centrifugal oil pump installation:
1. The right coupling should be coaxial. After installation, turn the coupling to confirm smooth operation without negative pressure before entering operation.
2. CYZ self-priming centrifugal oil pump is not suitable for transporting dirty oil, so an oil filter should be set at the inlet pipe end
3. The right coupling should be coaxial. After installation, turn the coupling to confirm smooth operation without negative pressure before entering operation.
4, the pump is not suitable for transporting dirty oil, so the oil filter should be set at the inlet pipe end.
Development: Self-priming centrifugal pump is widely used in municipal projects, factories, businesses, hotels, residential areas and other sewage discharge due to its simple installation, small footprint, convenient maintenance and noise-free. According to the "2009-2012 China centrifugal pump industry market analysis and investment value research report" released by Sump consulting shows that: in view of the problems existing in self-priming centrifugal pump, some domestic manufacturers focus on the development of pump protection system, automatically cut off the power supply when the pump operation is abnormal. Self-priming centrifugal pump in the future need to solve the problem is to improve the use of reliable, can adapt to a variety of working environment, optimize its structural design, further improve the ability of self-priming centrifugal pump. While this approach is effective and necessary, it is not the ultimate solution to the problem. But because the reliable aspect of sewage pump needs to be further strengthened, so improve the technical content of self-priming centrifugal pump products is the main direction of the future development of manufacturers. With the continuous development of economy, self-priming centrifugal pump by virtue of its strong sewage capacity, high efficiency and energy saving, self-priming performance and other advantages in production engineering application is more and more widely. Also applicable to water, sea water and acid, alkalinity medium viscosity less than or equal to 100 centiper, solid content up to 30℅ below chemical medium liquid and slurry with general paste. Therefore, we should focus on the house to improve the performance of the pump, from the root to solve the problem. Shang Pu consulting machinery industry analysts pointed out: at present, the domestic self-priming centrifugal pump is mainly produced and manufactured by domestic manufacturers, a small part is imported from abroad. Self-priming centrifugal pump market prospects are very broad. Not only can be applied to urban environmental protection, construction, fire, chemical, pharmaceutical, dye printing and dyeing, brewing, electric power, electroplating, paper making, petroleum, mining, equipment cooling, oil tanker unloading, etc.
