Product Description
Product Description
IR type pump is a horizontal single-stage single-suction water centrifugal pump, used for industrial and agricultural and urban, drainage, fire water supply, etc., the temperature is not higher than 120 ℃.
Overview
IR(IS) type pump is designed according to the performance and size specified in international standard IS02858. Its technical standards are close to international standards and reach the international advanced level. It is one of the energy-saving pump products promoted in China.
Structure Description
The pump has simple structure, reliable performance, small size, light weight, good cavitation resistance, low power consumption, and convenient use and maintenance.
The pump body and the cover part of the IR hot water single-stage pump are split from the back of the impeller, which is commonly referred to as the rear door opening structure. Its advantage is that it is convenient for maintenance. The pump body, suction pipeline, discharge pipeline and motor are not moved during maintenance. Only the intermediate coupling of the extension coupling is removed to exit the rotor parts for maintenance.
The casing of the pump (I. e., the pump body and the pump cover) constitutes the rotor of the pump's working chamber, impeller, shaft and rolling bearing. The suspension bearing part supports the rotor part of the pump, and the rolling bearing receives the radial and axial forces of the pump.
In order to balance the axial force of the pump, most of the pump impeller before and after are equipped with a sealing ring, and in the impeller back cover plate with a balance hole, because some pump axial force is not large, the impeller back without a sealing ring and balance hole.
The axial seal ring of the pump is composed of packing gland (9), packing ring (10), and packing (11) to prevent air intake or large amount of water leakage. If the impeller of the pump is balanced, the cavity equipped with soft packing is connected with the suction port of the impeller. If the liquid at the inlet of the impeller is in a vacuum state, it is easy to enter the air along the surface of the shaft sleeve. Therefore, a packing ring is installed in the packing cavity. Through the small hole on the pump cover, the pressure water in the pump chamber is led to the filling ring for sealing. If the impeller of the pump does not have a balance hole, the liquid pressure on the back of the impeller is greater than atmospheric pressure, so there is no problem of steam leakage, so the packing ring may not be installed.
In order to avoid damage to the shaft, a shaft sleeve is installed at the part where the shaft passes through the filling cavity for protection, and an O-shaped seal is installed between the shaft sleeve and the shaft to prevent air intake or water leakage along the mating surface.
The transmission mode of the pump is connected with the motor by extending the elastic coupling. The direction of rotation of the pump, viewed from the drive end, is clockwise.
