Abstract
Provided by the utility model is a testing apparatus for a pressure switch. The testing apparatus is characterized in that a spiral pressurization cylinder is connected to a pipeline; a pressure gauge is arranged on the pipeline; a pressure switch is connected to the end of the pipeline; and two ends of a buzzer are respectively connected with contacts of the pressure switch. According to the utility model, the pressure switch that needs to be tested is connected to the test pipeline; the spiral pressurization cylinder is used to carry out pressurization; the pressure gauge is used to display pressure values; and the buzzer is connected to the contacts of the pressure switch. If the pressure reaches a set value of the switch, the buzzer makes a motion to prove that the pressure switch is in a good state, thereby reducing the probability of the damage of the pressure switch after the installation and substantially reducing the time and manpower for the braking process.
Description
Technical field
This test unit belongs to trolley coach brake system test technical field, relates to a kind of pressure switch test unit.
Background technology
The pressure switch of usually installing on the vehicle is not tested its fine or not test unit, pressure switch directly is installed on the vehicle after coming, can the quality of pressure switch and force value reach the setting requirement, need to after finishing, brake test just can test, if therefore running into force value does not reach requirement, need to again change pressure switch, need to again do like this air-tight test of pipeline, and dismounting and setting pressure switch waste time and energy, and affects manufacturing schedule.
The utility model content
The purpose of this utility model provides a kind of test unit of finishing fast the pressure switch test, saving the production time, increase work efficiency.
For achieving the above object, the utility model provides a kind of pressure switch test unit, it is characterized in that: the spiral boosting cylinder is connected on the pipeline, and pipeline is provided with tensimeter, the terminal Bonding pressure switch of pipeline, and the hummer two ends are the contact of Bonding pressure switch respectively.
The pressure switch that the utility model will need to test is connected on the test pipeline, use the spiral boosting cylinder to carry out supercharging, show force value by draft gauge, hummer is connected on the contact of pressure switch, if when pressure reaches the setting value of switch, the hummer action proves that pressure switch is good, reduce the probability that damages after pressure switch is installed, and greatly shortened needed time of braking operation and manpower.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
With reference to accompanying drawing, 1 is the spiral boosting cylinder, needs this cylinder is connected with the test pipeline in the pressure switch process of the test.2 is tensimeter, needs this table is connected to T-valve top in the pressure switch process of the test, can show by tensimeter and different pressures value after the supercharging satisfy the pressure switch test of different pressures value.3 pressure switches for test are connected to the pipeline end with this switch, if force value reaches the setting value of switch, switch will move.4 is hummer, and the hummer two ends are connected in respectively on the contact of pressure switch, and when force value reached, the contact will be moved, and hummer has prompting, proves that this pressure switch is qualified.5 is air pipe line, and 6 is T-valve.This scheme not needing to have realized and will just can test quality after the pressure switch installation, do not need simultaneously picture to install needs in the past yet and use power supply just can test out the quality of pressure switch, all adopt machinery to control environmental protection and energy saving, practical, greatly accelerated manufacturing schedule.
Claims (1)
1. pressure switch test unit, it is characterized in that: the spiral boosting cylinder is connected on the pipeline, and pipeline is provided with tensimeter, the terminal Bonding pressure switch of pipeline, the hummer two ends are the contact of Bonding pressure switch respectively.
