Horizontal multi-stage boiler feed pump suitable for conveying water temperature is below 110 ° C or other physical and chemical properties similar to water and other non-corrosive liquids are widely used in industrial and mining enterprises boiler feed water and City life water supply, today Xiaobian graphic mode to say horizontal multi-stage boiler feed pump structure. Horizontal multi-stage boiler feed pump structure Analysis of the main horizontal multi-stage boiler feed pump shaft, sleeve, inlet, impeller, guide wing, seal ring, the middle section, the water section, balance ring, balancing plate, Tail cover. 1. Into the water section, the middle section, the water section and tail cover are made of cast iron, together to form a pump studio. 2. The impeller is made of cast iron, there are blades, the liquid enters along one side of the axial direction. Since the pressure of the multistage pump impeller varies from front to back, axial force must exist. The axial force is borne by the balance plate. Static equilibrium test. 3. The shaft is made of high-quality carbon steel with an impeller in the middle. The shaft, shaft sleeve and sleeve nut are fixed on the shaft. One end of the shaft is equipped with coupling parts and is directly connected with the motor. When viewed from the direction of rotation, the pump shaft rotates in the clockwise direction of the Chuan page. 4. The seal ring is made of cast iron to prevent the high-pressure water leakage back into the water part of the pump, respectively fixed in the water inlet section and middle section of the chemical pump, as wearing parts, worn spare parts replacement. 5. Centrifugal pump balance ring made of cast iron, fixed in the water section, which together with the balance plate balance device. 6. Balance plate made of wear-resistant cast iron, mounted on the shaft, located between the outlet section and the tail cover, balance axial force. 7. Chemical pump sleeve made of cast iron, located in two packing room, centrifugal pump for fixed impeller and pump shaft protection purposes. For wearing parts, worn spare parts can be replaced. 8. Bearings are used single row radial ball bearings, using calcium-based butter lubrication. 9. The packing acts as a seal to prevent air ingress and large amounts of liquid from escaping. Packing seal from the inlet section and tailgate on the filling room, packing gland, packing ring and packing and other components, a small amount of high-pressure water into the packing room from the role of water seal. The degree of tightness of the filler must be appropriate, can not be too tight, nor too loose, the liquid can drip to exudate prevail. If the packing is too tight, the sleeve can easily generate heat while consuming power. Filler is too loose, due to liquid loss to reduce pump efficiency.

Here are all BLACK & DECKER power tools and the designated carbon brushes,motor brushes, electric brushes, motor brushes, electric motor brushes or simply brushes.
For each power tool, there are usually two carbon brushes to choose from: With automatic stop and without automatic stop. Carbon brushes with automatic stop have a spring through the length of the carbon brush. When the carbon brush wears out, the spring gets released, the current to the carbon brush gets interrupted and your power tools switches off at once. The advantage: No additional wear and tear to your power tool. Carbon brushes without automatic stop do not stop functioning at once, but performance of your power tool will detoriate rapidly. Although handy as a warning sign, this usually isn't very beneficial to your power tool.
