Unit speed governor pressure oil tank fast pressure building method

The invention discloses a unit speed governor pressure oil tank fast pressure building method comprising the following steps: obtaining pressure oil tank parameter data, wherein the parameters comprise the pressure oil cylinder length L, cylinder diameter D, volume V-gland of two circular arc glands, and volume V-gas of a gas cylinder connected with the pressure oil cylinder; determining initial oil level L-initial of the pressure oil cylinder; calculating the final pressure P1 in pressure building according to the L-initial, wherein the calculation method is listed in the formula (see description), P refers to the gas rated pressure in the pressure oil cylinder, and V refers to the gas rated volume in the pressure oil cylinder; supplementing oil to the standard liquid level in the pressure oil cylinder when pressure is built up to P1. The method firstly determines to supplement gas to certain pressure P1 under certain initial oil level L-initial, and finally supplement pressure oil cylinder oil level to the
