Irrigation and drainage machinery is the main mechanization of agricultural mechanization and farmland water mechanization, and submersible pump is an important part of irrigation and drainage machinery, drought and drainage in agriculture to ensure yield and harvest plays an important role. The correct choice of agricultural stainless steel submersible pumps and agricultural stainless steel submersible pumps to carry out the necessary maintenance, so that it is in the best working condition, to ensure high yield and good harvest of agriculture.
structure:
(1) Pump shaft:
Role and structure. The role of the pump shaft is to transmit power and drive the pump impeller rotation, the shaft is generally supported by bearings, one end with a coupling or pulley, the impeller is fixed at the other end or in the middle. Axial pump shaft is slender, with the rubber bearing and packing contact surface is chrome or inlaid with stainless steel sleeve, in order to increase the wear resistance and corrosion resistance.
Maintenance.
Pump running for some time, the pump shaft will bend and wear, mainly due to impeller assembly imbalance, power shaft and pump shaft is not concentric, belt pull too tight, bearing installation skew, poor lubrication, so that early wear and tear pump shaft or bending. After this phenomenon, should be timely maintenance, to ensure the normal operation of the pump, otherwise it will cause the rotor imbalance and static and dynamic part of the wear and tear. After confirming that the pump shaft is bent, it must be straightened or replaced.
(2) Impeller:
Role and structure. Pump impeller is the power of mechanical energy is transmitted to the water and increase the energy of water. The impeller is composed of a blade and a hub. Impeller has a closed, semi-closed, open-type points.
Maintenance.
Impeller wear or damage caused by the general impeller imbalance or improper installation; as the pump shaft bending, shaft and power shaft is not concentric, the impeller was broken, the occurrence of cavitation, resulting in honeycomb-like holes. If the impeller wear too much or has been broken, the general should replace the new impeller.
(3) Pressure water chamber:
Role and structure. The function of the pressurized water chamber is to eliminate the rotational movement of the water and to convert it into pressure energy to send water to the outlet pipe or the next stage impeller. Centrifugal and mixed flow pump Common pressure chamber is spiral, called the volute. Volute generally single-stage suction, single-stage double-suction, multi-stage open water pump. Pump pressure chamber by the volute, guide vanes and other components.
Maintenance. Due to hot and cold, too much pressure or improper installation and other reasons, may cause volute or guide vane body cracks. Crack is not long, tightly sealed parts of the crack at both ends of the drilling of a small hole, so that no longer crack expansion, as a temporary solution. Crack, sealing the site should be strict requirements of cold, hot welding.
