A detecting joint for holding a vacuum pressure switch to be detected is arranged on the vacuum gas storage chamber, the power supply, the power switch, the vacuum pressure switch to be detected and a vacuum pump are electrically connected to form a loop providing the vacuum pump with electricity, the vacuum pump and the vacuum gas storage chamber are connected through a vacuum pipeline and carry out evacuation, and the pressure gauge is mounted on the vacuum pump, the vacuum gas storage chamber or the vacuum pipeline for indicating value of vacuum degree. The detecting joint for holding the vacuum pressure switch to be detected is arranged on the vacuum gas storage chamber, calibration and debugging are carried out after a current disconnection point of the vacuum pressure switch is read from readings of the pressure gauge, thereby the debugging and testing device guarantees the vacuum pressure switch to work within a set working range, is simple and speedy in operation, is safe and reliable, and can be widely applied to various occasions applying vacuum pressure switches.
Description
Technical field
The utility model relates to a kind of pressure switch pick-up unit, relates in particular to a kind of debugging detection device of vacuum pressure switch.
Background technology
At present; because the generation of energy crisis reaches the pay attention to day by day to environmental protection; countries in the world begin to develop pure electric automobile one after another; generally all be provided with especially vacuum brake power-assisted of brake power-assisted at present on the automobile; in fuel-engined vehicle; the vacuum tightness of inlet manifold is to guarantee the brake power-assisted when mainly relying on engine operation; but in electric automobile; generally all be to vacuumize by an electric vacuum pump; some producers begin to increase vacuum pressure switch and control the electric vacuum pump running in vacuum auxiliary brake device; avoid the electric vacuum pump continuous working and realize gap work; this just requires vacuum pressure switch is accurately detected the debugging calibration, prevents that being forbidden to cause vacuum auxiliary brake device power-assisted value because of the vacuum pressure switch cut-off point forms potential safety hazard inadequately.
The utility model content
Problem to be solved in the utility model provides a kind of practicality debugging detection device of vacuum pressure switch reliable, easy to detect.
The technical scheme that the utility model adopted is: debugging detection device of vacuum pressure switch, comprise vacuum pump, power supply, power switch, vacuum air storage chamber, tensimeter, described vacuum air storage chamber is provided with and detects interface in order to lay vacuum pressure switch to be measured, described power supply, power switch, vacuum pressure switch to be measured are electrically connected with vacuum pump and form the loop is the vacuum pump power supply, described vacuum pump is connected by vacuum pipe with the vacuum air storage chamber and vacuumizes, and described tensimeter is installed on vacuum pump or vacuum air storage chamber or the vacuum pipe in order to indication vacuum tightness value.
In the such scheme, described vacuum air storage chamber is provided with general quick-speed jigs in order to clamp vacuum pressure switch to be measured, again vacuum pressure switch to be measured is pressed in and detects on the interface on the described vacuum air storage chamber, detection is got up vacuum pressure switch is installed efficient and convenient like this, preferably being provided with sealing gasket on detection interface on the vacuum air storage chamber increases sealing after being pressed on interface at vacuum pressure switch to be measured, also can detect interface on described vacuum air storage chamber certainly and be provided with screw thread in order to connection vacuum pressure switch to be measured.
Preferred described vacuum air storage chamber is a vacuum air storage tank.
The beneficial effects of the utility model are: the utility model detects interface in order to lay vacuum pressure switch to be measured by being provided with on the vacuum air storage chamber, power supply, power switch, vacuum pressure switch to be measured are electrically connected the formation loop with vacuum pump be the vacuum pump power supply, read calibration debugging behind the current vacuum pressure switch cut-off point by pressure gauge reading, guarantee that vacuum pressure switch works in the working range value of setting, simple and quick, safe and reliable, can be widely used in the occasion of various application vacuum pressure switchs.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
