Description

V. Statement (A7 B7 The present invention relates to an improvement of a rotary pump, and more specifically to a cooling pump for a combustion engine. In a rotary fruit, the drive rod usually enters the pump A rotary mechanical seal is provided here. In the field of a rotary pump as an engine cooling pump in an internal combustion engine, the mechanical seal is not completely reliable. Its sealing surface can be coated with a chemical solvent layer, which can cause seal failure and Coolant leaks. These sealing surfaces may fail or leak prematurely due to excessive shaft operation. These sealing surfaces may also fail due to vibrations caused by the excessively tight driving of the poor bearings and the transmission of the drive belt. Therefore, these sealing surfaces may be damaged by Hard material in the pump media was scratched and worn away prematurely. In addition to the reliability problem, I know that in the past, mechanical seals could not completely remove leaks, even if they were in a new state. A machine The seal is composed of two polished radial surfaces that move close to each other. Because of the pressure system of the pumped media at the seal, Unlike the pressure of the outside air of the seal, a pressure gradient can be established between the seal faces, which can cause slower leakage or bleed. This can prove that a mechanical seal with a slight bleed is not always a failed seal .So a very useful cooling pump assembly usually does not need to be replaced. • However, I also know that a hermetic pump can be used as a magnetic coupling, which includes borrowing a fixed and closed sealed container or containing cover And a driving and driven magnetic member coupled to each other. According to this, the fixed container can prevent bubble leakage because it is a moving member. The disadvantage of this conventional magnetic light connection is that it has a large accumulation. Because The reduction of the space occupied by the internal combustion engine parts is increasingly required to be 'hence' the conventional knowledge cannot be achieved in the bone wheel or gear drive system and the cold -4- paper standard S China National Standard (CNS) A4 specification (210 × 297 mm) ";! :: ···: .1. ··% · Employees' Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs of the People's Republic of China Yinfan A7 ---------_ B7 V.

Liuxiang can be supplied from an radiator in a vehicle with this internal combustion engine to an inlet (not shown). The pump 10 should have an axial extension that is smaller than the conventional unsealed cooling millet. This is because the positioning of the pulley and the magnetic members 22 and 3 () is substantially linear. The bearing 24 is more suitable because it will The container 16 is compressed on the bearing 40 to provide a dynamic stabilization system. The bearing 40 should be made of a ceramic material, such as silicon carbide, which is resistant to compression. In another form, the driven magnetic member 30 may be constituted by an inductive magnetization driving consumable, which includes a ring of copper rods arranged axially, which may be suitable for being buried in a suitable base.
