Abstract
The invention relates to an engine ground test start oil supply control system, which comprises an oil supply device and a control device, wherein the oil supply device comprises a coarse oil filter, an electric oil pump, a fine oil filter, a reducing valve, a one-way valve and a solenoid valve which are sequentially connected through an oil pipe; the control device comprises a controller, an operating system, a display system, a data acquisition system and a pressure sensor; one end of the pressure sensor is connected with an oil outlet end of the oil supply device, and the other end of the pressure sensor is connected with the data acquisition system of the control device; and the controller is respectively connected with the solenoid valve and the electric oil pump. The oil supply is controlled according to engine start time sequence, and the igniting time of the engine can be guaranteed; and moreover, the engine is not required to be ignited by fire and can be continuously and repeatedly started, and the ignition cost is greatly reduced.
Description
Technical field
The present invention relates to a kind of control system, especially a kind of rocket engine ground test starting is for EFM Electronic Fuel Management.
Background technique
Aeroengine all needs to carry out the several times ground experiment before coming into operation at present, therefore need to carry out ignition start many times.But for some motor, for being adopted as disposable fire-working article cartridge ignition, if all adopt this mode at every turn, cost is high, resource is lost weary, complicated operation, does not utilize carrying out smoothly of product development such as certain bullet motor.If adopt fuel ignition blast mode to start, but motor itself only has main and auxiliary fuel feeding, does not start fuel feeding, can not satisfy the requirement of fuel ignition blast mode.
Summary of the invention
The invention provides a kind of cost low, easy and simple to handle, realize supply and the control of fuel oil, and can reach the rocket engine ground test starting confession EFM Electronic Fuel Management of continuous start-up function.
Technological scheme of the present invention is, control system comprises oil supplying device and control gear, described oil supplying device comprises the thick oil filter that is connected successively by oil pipe, electric oil pump, thin oil filter, reduction valve, one-way valve, solenoid valve, the other end of described thick oil filter is connected with oily tower, the other end of solenoid valve is connected with igniter nozzle, an oil circuit that manually operated valve is installed also is set between the oil outlet of described electric oil pump and the oily tower, be provided with an oil circuit between reduction valve oil outlet end and the oily tower, described control gear comprises controller, operation system, display system, data acquistion system and pressure transducer, described pressure transducer one end connects the oil outlet end of oil supplying device, the other end links to each other with the data acquistion system of control gear, described controller also respectively with solenoid valve, electric oil pump is connected.The oil outlet place of described thin oil filter and oil-feed place of solenoid valve are provided with pressure gauge, and described controller is the PLC programmable controller.The control apparatus of described controller, operation system, display system, data acquistion system and test bay shares.
Thin oil filter of the present invention guarantees that the turbidity test of input fuel oil prevent plug nozzle; The electric oil pump fuel feeding provides the pressure fuel oil; Reduction valve is adjusted the front fuel outlet constant pressure of nozzle, can be stabilized in different value according to different demands; Manually operated valve is normally closed, can be manually opened when emergent, to cut off fuel delivery, the protection motor; Solenoid valve is realized fuel feed control; Pressure before the pressure transducer gaging nozzle monitors to the number extraction system signal feed back.The unidirectional protection valve prevents that fuel oil from flowing backwards, and produces vent plug when avoiding starting.Part system of the present invention and test bay control apparatus share, and cost is lower, and fuel feeding is stable, can adjust according to the performance of motor the oil-gas ratio of charge oil pressure and then adjustment starting period.This equipment can independently be installed in the test bay, can be used as test bay equipment, need not be installed on the motor.For a certain motor, starting is after fuel pressure adjusts, just can stable ignition, do not need frequent adjustment.Motor is when ground experiment, lighting the formation of starting fuel oil with electric igniter ignites the torch, ignite the torch and light auxiliary fuel and finish engine ignition, because according to engine start time-oriented sequential control fuel feeding, can guarantee engine ignition opportunity, guarantee the engine ignition starting, make motor need not use cartridge ignition, and can continuous several times start, the igniting cost reduces greatly.
