Abstract

The present invention discloses a water pump durability test bench, which includes a programmable controller, a frequency transformator, a variable-frequency motor, a water tank, a first waterpipe, a second waterpipe, a workstation and a chucking appliance, wherein the chucking appliance fixes the water pump onto the workstation; the first waterpipe connects with a pump intake and the water tank outlet respectively; one end of the second waterpipe connects with outlet of the water pump and the other end inserted into the water tank; the programmable controller, the frequency transformator and the variable-frequency motor are connected in series through cables; the programmable controller sets frequency of the frequency transformator and start and stop time to control the frequency transformator outputs pressure frequency and drive the variable-frequency motor operate according to given rate of speed and drag the water pump operate. The water pump durability test bench of the invention has compact structure, low cost, high precision, automatic controllable test process, and suitable for small and medium-sized laboratories.

Description

technical field [0001] The invention relates to a water pump test stand, in particular to a water pump durability test stand. Background technique [0002] The water pump is an important part in the cooling system of the automobile engine. Its function is to pump the coolant, so that the coolant can flow rapidly in the engine cooling water channel, take away the heat generated during the engine operation, and maintain the normal working temperature of the engine. [0003] If the water pump fails, it will make the water temperature too high and may cause engine failure. In fact, in the engine failure, the failure caused by the high water temperature occupies a very high proportion, and the high water temperature is caused by the failure of the water pump. Generally speaking, the water pump of the engine has entered a period of high incidence of failure when it has been used for about 100,000 kilometers. In order to ensure the quality of maintenance, many water pumps are mai...
