Problems solved by technology

1. For the test method of spraying tap water on the road surface, since the asphalt sprinkler sprays emulsified or low-concentration asphalt when it is working, the viscosity and density of the two are significantly different from water, that is, the method of spraying tap water is It cannot truthfully and accurately reflect the spraying performance of the asphalt distributor, and long-term spraying of tap water will greatly damage the high-value asphalt pump; The test method will not only delay a lot of working time, but also affect the quality of the project, causing inconvenient maintenance, and the test cannot be carried out continuously
The main disadvantages of the above two testing methods are low efficiency, incomplete testing, and failure to ensure that the factory quality of the equipment reaches the standard to the greatest extent.

Embodiment Construction

[0018] Such as figure 1 As shown in the figure, a spraying performance testing device of an asphalt distributor includes an oil pool 1 and an oil storage tank 2. The oil pool 1 is arranged above the oil storage tank 2, and an oil delivery pipe 3 is arranged between the bottom of the oil pool 1 and the oil storage tank 2. One end of the oil delivery pipe 3 is located at the bottom of the oil pool 1, and the other end extends into the oil storage tank 2. The oil delivery pipe 3 is provided with a switch valve 4 that can be switched on and off, and an oil level gauge 5 is fixedly arranged on the inner wall of the oil pool 1. An oil discharge pipe 6 is also arranged at the bottom of the oil pool 1, and an oil discharge valve 7 is arranged on the oil discharge pipe 6, and the oil delivery pipe 3 and the oil discharge pipe 6 are cross-communicated. When the test is over, close the on-off valve 4 and open the oil discharge valve 7 to discharge the mixed oil more conveniently and thor...

Abstract

The test apparatus comprises: an oil pool, and an oil tank. The oil pool is located above the oil tank; there is a oil pipeline located between said oil pool and oil tank; one end of the pipeline is located at the bottom of the oil pool, and the other end of the pipeline enters into the oil tank; there is a controllable switch valve located on the pipeline; on the inner wall of the oil pool thereis a oil level scale.

Description

technical field [0001] The invention relates to a test device for the spraying performance of an asphalt distributor and a test method thereof, and belongs to the improvement technology of the spray test device and the test method of the asphalt distributor. Background technique [0002] At present, the performance test of asphalt distributors is generally carried out by spraying tap water on the road before leaving the factory or directly testing while working on the construction site. 1. For the test method of spraying tap water on the road surface, since the asphalt sprinkler sprays emulsified or low-concentration asphalt when it is working, the viscosity and density of the two are significantly different from water, that is, the method of spraying tap water is It cannot truthfully and accurately reflect the spraying performance of the asphalt distributor, and long-term spraying of tap water will greatly damage the high-value asphalt pump; The test method will not only d...
