In the method for the conveying material, main oil pump 5 provides power during material conveying, and auxiliary oil pump 6 provides suction and material
The power of precompressed, by reversal valve 8 and the interoperation of on-off valve 9, make two piston type delivery pumps 1 within the time of switching all
By the fuel feeding of main oil pump 5, not by the interference of auxiliary oil pump 6, in suction and precompressed by the fuel feeding of auxiliary oil pump 6, it is to avoid interference main oil pump 5 is pressed
Material is sent, two pressure oil-sources are not interfere with each other, beneficial to the stability for improving conveying material, while in two piston types conveyings of switching
During the force feed material of pump 1, two difference force feed materials of piston type delivery pump 1 and guarantor are first driven using same pressure oil-source
Hold compressed material, reconvert discharging switch valve 3, due to two piston type delivery pumps 1 in the transfer process for the switch valve 3 that discharges
Discharging opening there is a situation where to open simultaneously, two piston type delivery pumps 1 force feed material simultaneously within the period, and now two
Individual piston type delivery pump 1 drives force feed material by same pressure oil-source fuel feeding, makes two force feed materials of piston type delivery pump 1
Speed sum keeps constant, forms the steady switching of pulse free, and the stability of material conveying is so completely secured；This
Outside, material is carried out precommpression by this method before force feed material, can eliminate because the viscosity of material it is big caused by suction
Interior sky.
It the above is only preferred embodiment of the present utility model, protection domain of the present utility model is not limited merely to above-mentioned
Embodiment.To those of ordinary skill in the art, under the premise of the utility model technical concept is not departed from obtained by
Modifications and variations also should be regarded as protection domain of the present utility model.
