Embodiment Construction

[0021] Attached below figure 1 The present invention is described in further detail:

[0022] First, the role of the main components:

[0023] Heater 14: Heating the temperature of the cooling liquid to reduce the production cycle.

[0024] Temperature sensor 4: Control whether the heater works according to the value measured by the sensor, so that the temperature of the coolant is controlled between 70 and 80 degrees.

[0025] Water pump 2: Automatically supply coolant to the engine.

[0026] Pressure regulating valve 3: reduce the output pressure of the water pump, otherwise it will affect the normal operation of the engine water pump.

[0027] Liquid level gauge 5: Measure the liquid level of the water tank. If the liquid level is too low, the system will control the replenishment valve to open to supplement the coolant.

[0028] Vacuum generator 6: generate vacuum and suck back the coolant;

[0029] Supplementary valve 12: After the hot test of each engine, a certain ...

Abstract

The invention discloses a coolant system of a heat testing machine of an automobile engine and a treatment method. The invention heats the coolant to be about 80 DEG C, thus saving the warming-up time when in heat test and reducing production rhythm; the filling is carried out automatically and the coolant is recovered, thus reducing the production rhythm; compressed air is used to carry out leakage test on the whole pipeline before the engine runs so as to solve the problem that the coolant pipeline is aged to produce leaked coolant; if the leakage is generated, the following test steps are not carried out. The water pump is used for automatically filling the coolant before the engine runs, and after the engine test is finished, the coolant in the pipeline is recovered by a mode of combining compressed air blowing and a vacuum generator so as to solve the problem of residual coolant after the heat test. Compared with the original cooling system of the heat testing machine, the system and the method shorten the production rhythm and avoid the leakage of the coolant system when the engine is in the heat test.

Description

technical field [0001] The invention mainly relates to a cooling liquid system and a processing method of a thermal test machine of an automobile engine. Background technique [0002] The coolant system of the engine hot test machine is mainly responsible for supplying the engine with the necessary coolant when the engine is running, which has the same function as the whole vehicle. But the coolant system of the hot test machine has its own particularity. [0003] First of all, the production cycle of the whole hot test is very short. Secondly, after the hot test of the engine, a large amount of coolant remains in the engine. If the connection is directly removed, a large amount of remaining coolant will leak, which will pollute the environment on the one hand and waste costs on the other. [0004] The coolant system of the previous hot test machine is similar to that of the whole vehicle, except that a drain valve is added at the lowest coolant pipe joint of the engine. ...
