Description

Technical Field

[0001] The utility model relates to the technical field of engine detection, in particular to a device capable of detecting the degassing ability of a whole vehicle. Background Art

[0002] All non-road mobile machinery with a power of 560kW or less (including 560kW) produced, imported and sold and the diesel engines used in them must meet the requirements of the national Stage IV emission standards.

[0003] The cooling system of the whole vehicle is a closed circulation system, and the circulation of coolant helps the engine consume excess heat. In actual use, water vapor is easily formed in the cooling system, especially when the heat load is relatively large. These water vapors, including some gases leaking from the pipe joints, will enter the circulation along with the cooling water. If these gases are not removed in time, air blockage will occur. Once air blockage occurs, the engine cooling capacity will be significantly reduced. The air entering the cooling circulation system will have the following harmful effects: (1) Air will cause air blockage in the water channel with a smaller diameter, making the coolant flow in the local water channel of the engine unsmooth and reducing the heat transfer coefficient; (2) The air will expand rapidly due to heat, causing cavitation of the cylinder liner, resulting in premature cracks or water leakage in the cylinder liner. The expanded air may also cause the coolant to overflow; (3) When there is too much air entering the circulation system, the water pump will be sucked empty, the working efficiency of the water pump will be reduced, and in severe cases, the cooling system will fail.

[0004] To avoid the above abnormal phenomena in the cooling system cycle, the generated water vapor (or bubbles) must be removed in time. Therefore, another important indicator for evaluating the cooling system function is its degassing ability, which not only requires that the air in the cooling system can be completely discharged during the coolant filling process, and there is no dead corner where air is trapped, but also requires continuous forced removal of the air inhaled during operation and the steam generated by the vaporization of liquid at high temperature or the gas that penetrates due to the poor sealing of the cylinder gasket.

Utility Model Content

[0009] The utility model (mainly) aims to provide a device for detecting the degassing capacity of a whole vehicle which has a simple structure and is suitable for a small space.

[0010] To this end, the utility model proposes a device capable of detecting the degassing ability of a whole vehicle.

[0011] Preferably, the utility model may also have the following technical features:

[0012] A device capable of detecting the degassing capacity of a whole vehicle comprises a sealing hose I, a sealing hose II and a right-angle elbow, wherein the right-angle elbow is a transparent glass tube, and both ends of the right-angle elbow are respectively connected to the sealing hose I and the sealing hose II by clamps; the other end of the sealing hose I is connected to the water inlet pipe of the engine water pump, and the other end of the sealing hose II is connected to the water outlet pipe of the whole vehicle water tank.

[0013] Furthermore, the length of the straight pipe sections at both ends of the right-angle elbow is twice the width of the clamp.

[0014] Furthermore, convex ribs in the circumferential direction are provided at both ends of the right-angle bend pipe.

[0015] Furthermore, the convex rib is located between the clamp and the end face of the right-angled bend pipe clamped by the clamp.

[0016] Furthermore, the outer arc length of the bend of the right-angle bend pipe is greater than or equal to 5 cm.

[0017] The beneficial effects of the utility model compared with the prior art include: the present embodiment adopts a right-angle elbow to replace the commonly used straight pipe, which occupies less space, can adapt to smaller space use, and has a wider range of applications. In actual application, due to the limited use space provided by different models, equipment such as the test tool disclosed in patent document CN202022846155.0 cannot meet the use space environment of some models due to the large space occupied, while the right-angle elbow structure adopted in the present embodiment can reduce the space required for detection, can meet the space environment requirements of all models, and has a wider range of applications. The device is convenient and simple to use, has strong operability, and simplifies the complexity of the test. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with specific implementations and in conjunction with the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.

[0020] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts unless otherwise specifically stated.

[0021] like Figure 1 A device for detecting the degassing capacity of a whole vehicle is shown, comprising a sealing hose I2, a sealing hose II5, and a right-angle elbow 4. The right-angle elbow 4 is a transparent glass tube, and its two ends are respectively connected to the sealing hose I2 and the sealing hose II5 through a clamp 3. The other end of the sealing hose I2 is connected to the engine water pump inlet pipe 1, and the other end of the sealing hose II5 is connected to the vehicle water tank outlet pipe 6. At present, the commonly used device for testing the degassing capacity of the whole vehicle generally adopts a transparent straight glass tube for observation (such as patent document CN202022846155.0), which is suitable for places with larger spaces, but not suitable for smaller spaces, and cannot be effectively installed and detected. On the one hand, the present embodiment adopts a right-angle elbow instead of the commonly used straight pipe, which occupies less space, can be adapted to smaller spaces, and has a wider range of applications. In actual application, due to the limited usage space that different models can provide, equipment such as the test tool disclosed in patent document CN202022846155.0 cannot meet the usage space environment of some models due to its large space occupation. The right-angle elbow structure adopted in the present embodiment can reduce the space required for detection, can meet the space environment requirements of all models, and has a wider range of applications. On the other hand, the present embodiment adopts a detection mechanism composed of sealing hose I, sealing hose II, and right-angle elbow, which has a simpler structure and is easy to install.

[0022] The sealing hose I2 and the sealing hose II5 are fixed on the right-angle bend pipe by the clamp 3 to prevent them from falling off. During installation, the length of the straight pipe section at both ends of the right-angle bend pipe 4 can be shortened as much as possible, and the length of the straight pipe section is preferably twice the width of the clamp 3. Preferably, in order to improve the anti-falling effect of the sealing hose I2 and the sealing hose II5, the clamping force of the clamp 3 on the right-angle bend pipe 4 is reduced. A convex rib 7 in the circumferential direction is provided at both ends of the right-angle bend pipe 4. When the clamp 3 is locked, the convex rib 7 is located between the clamp 3 and the end face of the right-angle bend pipe clamped by the clamp 3. In this way, the anti-falling risk of the sealing hose I2 and the sealing hose II5 can be greatly improved through the limiting effect of the convex rib 7. Moreover, the convex rib 7 can also play a role in strengthening the seal, so that two sealing points are formed at the convex rib 7 and the clamp 3, further improving the sealing effect.

[0023] Before the test begins, put the sealing hose I2 on the upper left end (vertical position) of the right-angle elbow 4 of the device, and then fix it with a clamp 3; then put the sealing hose II5 on the lower right end (horizontal position) of the right-angle elbow 4, and then fix it with a clamp 3; put the sealing hose I2 on the engine water pump water inlet pipe 1, and then fix it with a clamp 3; put the sealing hose II on the vehicle water tank outlet pipe 6, and then fix it with a clamp 3; finally tighten the clamps at all places. Through the bend of the transparent right-angle elbow 4, observe the bubbles in the liquid in the wiper tube and compare them with the design standards to confirm whether the fluid bubble state of the coolant meets the specification requirements, thereby determining the degassing capacity of the vehicle. After the diesel engine is started, the test can be carried out according to the corresponding standard specifications or by itself as needed. When the engine has been running for a certain period of time and the coolant reaches a certain temperature, the engine thermostat is opened, and the real-time state of the coolant fluid in the right-angle elbow 4 can be more clearly seen. Preferably, the outer arc length of the bend of the right-angle bend pipe 4 is greater than or equal to 5 cm.
