in the debugging stage, the first valve rod is separated from the first valve ball by rotating the first valve rod; air in the hydraulic cavity passes through the first air outlet channel and the first air outlet hole, then pushes up the first valve ball to enter the first valve cavity, and enters the chassis after passing through the first air outlet channel and the first connecting channel; after debugging is completed, reversely rotating the first valve rod to enable the bottom end of the first valve rod to prop against the first valve ball; in the normal operation process, when air in the hydraulic cavity gathers to reach a certain pressure, the air enters the safety valve through the second air outlet channel and then enters the chassis through the second air outlet channel and the first air outlet channel;
in the debugging stage, the second valve rod is rotated to separate the second valve rod from the third valve ball, the third valve ball descends, and hydraulic oil in the chassis enters the third valve cavity through the second connecting channel and the first oil inlet channel and then enters the second oil inlet hole; then the second valve ball is propped open to enter a second valve cavity, and enters the hydraulic cavity through the first oil inlet hole and the first oil supplementing channel to supplement oil; after debugging is completed, reversely rotating the second valve rod to enable the top end of the second valve rod to prop against the third valve ball, and sealing the bottom end of the second oil inlet hole; and in normal operation, the second oil supplementing valve is utilized for supplementing oil.
2. The reciprocating pump for reducing debugging time according to claim 1, wherein a second oil supplementing channel and a second oil inlet channel are arranged on the transition plate, and the second oil supplementing channel is communicated with the hydraulic cavity and an oil outlet of the second oil supplementing valve; and two ends of the second oil inlet channel are respectively communicated with the oil inlet of the second oil supplementing valve and the first oil inlet channel.
