Abstract
The utility model provides a ground energy output pressure real-time display device of an electrohydraulic servo mechanism. The device consists of a pressure transmitter, an intelligent digital display instrument and a transmission line, wherein the transmission line comprises a four-core cable, a seven-core plug and an intermediate switch cabinet; the pressure transmitter is connected with a ground energy pressure output port and is connected with the intelligent digital display instrument in a control room through the four-core cable and the seven-core plug; and the output pressure of the transmitter is displayed, controlled and output in a linear transmission manner by the intelligent digital display instrument so as to realize real-time display of the pressure at the valve inlet of an actuator and ensure the test reliability.
Description
Technical field
The utility model relates to solid propellant rocket ground firing technical field, particularly a kind of solid propellant rocket ground firing electrohydraudic servomechanism ground energy output pressure real-time displaying device that is used for.
Background technology
Electrohydraudic servomechanism is one of important composition parts of solid propellant rocket ground experiment thrust vector TT&C system, is the topworks of engine jet pipe swing, in ground experiment, uses the ground energy for it power to be provided.The high and low pressure pressure transducer is installed on servo control mechanism usually, measures the oil sources output pressure, judge with this whether the electrohydraulic servo valve inlet pressure satisfies technical requirement, and whether the working condition of the ground energy and actuator is normal.But because servo control mechanism of new generation is carried out servo control mechanism technical standard on the bullet, so structure, interface and the former actuator of new actuator are different, it has mainly cancelled actuator import and export high-low pressure pressure transducer.Caused in ground experiment, can't realizing to judge to actuator valve inlet pressure supervision and record whether valve inlet pressure satisfies technical requirement, can't guarantee the reliability of actuator and ground working energy, normally brought hidden danger for test.To the above-mentioned shortcoming and defect of mentioning, and servo actuator can not the property transformed, according to valve inlet pressure and the close principle of ground energy pump discharge pressure, can well address the above problem through setting up ground energy output pressure real-time displaying device.
The utility model content
The utility model has been realized the real time monitoring to electrohydraudic servomechanism servo-valve inlet pressure with the change of minimum, and equipment is simply efficient, is independent of outside the TT&C system stable performance.Newly added equipment does not produce any interference and interference to original TT&C system when warranty test normally carries out, assurance the test reliability.Adopt ground energy output pressure real-time display method, can judge, guaranteed the reliability of actuator, satisfactorily accomplished various model engines ground test missions electrohydraudic servomechanism servo-valve inlet pressure.
The utility model above-mentioned purpose realizes through following proposal:
A kind of electrohydraudic servomechanism ground energy output pressure real-time displaying device comprises:
Pressure unit is mainly used in to gather ground energy output pressure and become and send output;
Transmission line comprises long apart from shielded multiconductor cable and connector;
Intelligent digital displaying is mainly used in the direct supply that regulation is provided for pressure unit, and the voltage signal change of pressure unit output is sent to the pressure value of correspondence and demonstration in real time, can set the top pressure limit value, overload alarm.
Transmission line connects pressure unit and intelligent digital displaying, is used to transmit direct supply and analog voltage signal, and pressure unit is connected with ground energy pressure output.
Transmission line uses four-core shielded cable, military seven core plugs, intermediate transit cabinet, and the four-core shielded cable connects the intermediate transit cabinet as transmission cable through military seven core connectors.
