WATERPUMP FOR COOLANT TRANSPORTATION IN A LOW TEMPERATURE- AND HIGH TEMPERATURE CIRCULATION SYSTEM

摘要

The present invention relates to a water pump (1) for conveying the coolant in the low-temperature and high-temperature circulation circulation will, the water pump is a low temperature, including low temperature spiral housing (3) located on the inside (2) and the first mounting surface 4, including the high-temperature hot spiral housing (6) located on the inside (5) and the second the mounting surface, the low temperature spiral (3) and the hot spiral (6) in the same time for conveying the coolant water pump rotor 8 and the water pump rotor (8) the drive shaft (9) for driving the has, in this case the water pump (1) is the first mounting surface in the finished state is tangent to the second mounting surface under the intermediate connection of the heat insulator 10, the two mounting surfaces are a first plane (E1) formation, said first plane (E1) is placed between the low temperature spiral (3) and the hot spiral (6).
