Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
Fig. 1 is the block diagram of overall engineering machine provided by the invention heat radiation testing apparatus 10, and as shown in Figure 1, this equipment 10 comprises receiving trap 101 and treating apparatus 102.This receiving trap 101 is for receiving the temperature of the relevant parts that to dispel the heat with complete machine, according to the dispel the heat temperature of relevant parts of complete machine, treating apparatus 102 dispelling the heat after the temperature of relevant parts reaches thermal equilibrium temperature with complete machine, determines whether abnormal engineering machinery dispels the heat.
Should be understood that, be not the temperature of all parts that requirement is dispelled the heat in relevant parts with complete machine reach respective all simultaneously thermal equilibrium temperature after just can determine whether abnormal engineering machinery dispels the heat according to the dispel the heat temperature of relevant parts of complete machine, as long as the temperature of any one or more parts that should dispel the heat in relevant parts with complete machine reaches its thermal equilibrium temperature, just can determine that whether the temperature of these one or more parts is normal according to the temperature of the one or more parts reaching thermal equilibrium temperature, thus determine that whether engineering machinery heat radiation is abnormal.
When carrying out overall engineering machine heat radiation test, should be noted that: experimental prototype should complete comprehensive running-in; Engine speed should adjust in specialized range; Coolant-Level should remain in the scope that heating radiator specifies; Hydraulic reservoir liquid level should reach requirement oil level; Thermostat is in normal operating conditions.In addition, operating personnel also should require to test according to engineer machinery operation, and uninterruptedly carry out operation, when needing the personnel of replacement operation engineering machinery, replacing construction is not more than 1 minute.When engineering machinery is such as dozer, can carries out heavily loaded dozing, more than second gear carry out fast reverse when returning with one grade, too fast to prevent temperature from declining, soil-shifting haul distance is within the scope of 20m ~ 40m, and the soil-shifting degree of depth can not be greater than blade height.
At least one temperature following is comprised: engine water tank water inlet temperature, engine water tank outlet temperature, torque converter inlet temperature, torque converter outlet temperature, torque converter cooler inlet temperature, torque converter cooler outlet temperature, handling maneuver valve inlet temperature, operating oil tank temperature, power transmission-gear box temperature, rear axle box temperature, the whole transmission temperature in left side, the whole transmission temperature in right side with the dispel the heat temperature of relevant parts of complete machine.
According to the dispel the heat temperature of relevant parts of complete machine, treating apparatus 102 determines that engineering machinery is dispelled the heat whether abnormal can carrying out in the following manner: each of dispelling the heat in the temperature of relevant parts with complete machine and temperature threshold corresponding with each of dispelling the heat in the temperature of relevant parts with complete machine respectively compare by treating apparatus 102, when being greater than the corresponding temperature threshold of the temperature of the relevant parts that to dispel the heat with this and complete machine with any one of dispelling the heat in the temperature of relevant parts of complete machine, treating apparatus 102 determines that engineering machinery heat radiation is abnormal.For example, the temperature of relevant parts of supposing to dispel the heat with complete machine comprises torque converter inlet temperature and torque converter outlet temperature, treating apparatus 102 by the temperature threshold of torque converter inlet temperature and torque converter inlet temperature (namely, the temperature threshold corresponding with torque converter inlet temperature) compare, and by the temperature threshold of torque converter outlet temperature and torque converter outlet temperature (namely, the temperature threshold corresponding with torque converter outlet temperature) compare, if torque converter inlet temperature is greater than the temperature threshold of torque converter inlet temperature and/or (namely torque converter outlet temperature is greater than the temperature threshold of torque converter outlet temperature, the corresponding temperature threshold of the temperature of the relevant parts that to dispel the heat with this and complete machine is greater than) with any one of dispelling the heat in the temperature of relevant parts of complete machine, then treating apparatus 102 determines that engineering machinery heat radiation is abnormal.
Receiving trap 102 is also for receiving actual environment temperature, treating apparatus 102 is according to the theoretical environment temperature preset, actual environment temperature and to dispel the heat the corresponding temperature threshold preset of the temperature of relevant parts with complete machine, obtains dispelling the heat the corresponding temperature threshold of the temperature of relevant parts with complete machine.Generally, what technician grasped dispels the heat the temperature of the relevant parts corresponding temperature threshold preset for set by theoretical environment temperature (being generally 45 DEG C) with complete machine, so need here to obtain dispelling the heat the corresponding temperature threshold of the temperature of relevant parts with complete machine according to actual environment temperature conversion.Generally, when theoretical environment temperature, torque converter inlet temperature threshold value and torque converter outlet temperature threshold value are 120 DEG C, power transmission-gear box temperature threshold is 120 DEG C, rear axle box temperature threshold is 120 DEG C, operating oil tank temperature threshold is 100 DEG C, and the whole transmission temperature threshold of the whole transmission temperature threshold in left side and right side is 100 DEG C, and engine water tank water inlet temperature threshold and engine water tank outlet temperature threshold value are 102 DEG C.
