Embodiment Construction

[0045] The specific implementation and examples of the present invention will be described below in conjunction with the accompanying drawings.

[0046] Depend on figure 1 , figure 2 , image 3 It can be seen that the main structure of the device of the present invention is a closed chamber, which communicates with the outside only through the inlet (18) and outlet (2) on it, and the chamber is divided into a smaller rotor chamber (6) and a larger heating chamber (3) two parts, the two parts communicate through the rotor cavity, the positional relationship between them is that the rotor cavity is on a side wall of the heating cavity (3), and the rotor cavity (6) and the rotor cavity shell (4) are formed by The rotor cavity mouth protrudes outside the heating cavity (3). Such a positional relationship shows that the rotor cavity opening is the interface between the rotor cavity (6) and the heating cavity (3). After the front bearing (5) is installed on the rotor cavity open...

Abstract

A circulating preheater with single cavity permanent magnet rotor ( PMR ) pump is featured as preparing cavity body rotor and cavity shell by plastic injection molding for setting then in one body or one body connected structure ; setting outlet , front head opening , electro thermal tube ( ET ) opening at bottom and separated stator slot on cavity body ; installing PMR , front hearing and impeller in rotor or heating cavity from front head opening ; installing ET spiral portion in heating cavity from its own opening ; filling and sealing stator in stator slot ; setting temperature sensing component on external side surface of ET fixture disc and setting junction box below ET fixture disc and stator slot . The ET should be installed first when assembling operation is carried out.

Description

technical field [0001] The invention relates to a circulating preheater for a single-cavity permanent magnet rotor pump and an assembly method thereof, which belongs to the field of motor vehicle engine electric preheaters, and can also be applied to preheating, heating, and temperature control of other engines and other machinery and equipment. And electric heaters, water heaters and other fields. Background technique [0002] In a low temperature environment, motor vehicle engines will have difficulty starting due to fuel condensation, oil viscosity and other reasons. The most ideal way to solve this problem is to heat the engine in advance, this process is generally called warm-up. Through preheating, the cold start becomes a hot start, which not only starts smoothly, but also greatly reduces engine wear, and can also greatly reduce the emission of polluting gases in the engine exhaust and reduce fuel consumption. [0003] In order to achieve preheating, a preheater is ...
