15, liquidometer 14 and air filter 13 etc..This hydraulic system oil liquid is exported after the inlet port of plunger pump 2 by oil outlet dynamic
Power connects electromagnetic relief valve 5, another way is through the high pressure filter with bypass circulation using two-way is divided into after check valve 4 all the way
6 are respectively connected with a fluid-control one-way in two total working chambers after servo valve (proportioning valve) 7 to servo valve (proportioning valve) 7
Two solenoid directional control valves 11 are arranged in four hydraulic fluid ports of oil cylinder in valve 8.
Plunger pump 2 selects power output source of the constant pressure variable plunger pump of double-stage pressure-regulation as hydraulic system, output power
Oil realizes the switching to system pressure by the solenoid directional control valve integrated on control pump;Check valve 4 plays guarantor to plunger pump 2
Shield effect prevents system oil liquid from flowing backwards driving pump and rotates backward;Electromagnetic relief valve 5 is used as system safety valve, transports safely to system
Row provides safeguard;High pressure filter 6 provides clean oil to the operation of servo valve (proportioning valve) 7, prevents large-scale impurity from entering

Hydraulic lock is formed in, and locking is carried out to executing agency after system-down;Solenoid directional control valve 11 can switch operating condition in system
The switching of Shi Shixian working oil path.
The first high speed of a ship or plane operating condition:
Activation system, system enter the first high speed of a ship or plane regime mode, and plunger pump 2 exports the first system pressure P1.?
Under the operating condition, load torque M1 is big, and system pressure P1 is big, and rotational angle is small, and rotational angular velocity ω 1 is small, and flow system flow Q1 is smaller.
It is calculated according to system power W=P*Q/60, it is known that the output power W1 under the operating condition.
Second of low zero power test operating condition:
Activation system, system enter second of low zero power test regime mode, and plunger pump 2 exports second of system pressure P2,
System pressure P2≤P1.The operating condition is compared to the first high speed of a ship or plane regime mode, and load torque M2 is relatively small, system pressure
P2 is smaller, and rotational angle is big, and rotational angular velocity ω 2 is larger.Due to the oil circuit switching of executing agency at this time, working oil chamber volume subtracts
Half, rotational angular velocity is about 2 times of the first operating condition, therefore flow system flow variation is little.It is calculated according to system power W=P × Q/60,
Know that the output power under the operating condition is small compared with the first operating condition.
Both the above operating condition exists at work, and needs to switch operating condition according to the different speed of a ship or plane, but traditional sets
Meter mode is selected without oil circuit, be will cause output power and is doubled than the design.According to power W=P × Q is calculated, in pressure phase
Deng in the case where, flow is doubled, then system power doubles.
The above is only a specific embodiment of the invention, it is noted that those skilled in the art are come
It says, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should be regarded as
Protection scope of the present invention.
