Construction and working principle of submersible pump for deep well
Weihu pump submersible pump for deep well specifications of more than 400, QJ well submersible pump is the core product. Do you know about the construction and working principle of submersible pumps?
1. submersible pump for deep well construction
Well submersible pump is composed of pump body, water pipe, pump seat, submersible motor (including cable) and starting protection device. The pump body is the working part of the submersible pump, which consists of water inlet, diversion shell, check valve, pump shaft and impeller and other components. Between the pump body and the submersible motor, the flange surface is connected with bolts, and the two shafts are connected by coupling. The pipe is also bolted. The motor is a water-filled rubber-sheathed cable with a water-proof rubber sheathed cable. The starting protection device should use a self-aging decompression starting box with overload, undervoltage, and phase protection.
2. submersible pump for deep well working principle
By the submersible motor drive submersible pump impeller rotation, so that the impeller inlet to form a vacuum, the water inhalation, the role of the impeller in the impeller produced under the centrifugal force, in order to obtain the speed and pressure energy. With a certain amount of energy through the guide shell, into the next level of the impeller, with the pump series increases, the pressure continues to increase, and finally through the water pipe and pump into the ground pipeline system.
