Embodiment Construction

[0022] The high temperature resistant miniature adjustable plunger type lubricating flow pump includes a pump body 1, a counterbore is opened on the top surface of the pump body 1, a piston rod counterbore is opened at the bottom of the counterbore, and a piston rod counterbore is arranged inside the counterbore. There is a piston rod 2 whose outer diameter matches the piston rod counterbore, a spring is supported between the lower end of the piston rod 2 and the bottom of the piston rod counterbore, and the side walls of the piston rod 2 are respectively along the circumferential direction and the generatrix direction of the piston rod 2 There are horizontal oil guide grooves 3 and vertical oil guide grooves 4 oppositely arranged. A through hole is provided between the horizontal oil guide groove 3 and the vertical oil guide groove 4. The horizontal oil guide groove 3 and the vertical oil guide groove 4 are connected. The central angle of the pair is less than or equal to 90 d...

Abstract

The invention relates to a lubrication liquid flow pump, in particular to a high-temperature-resistant minisize adjustable plunger-type lubrication flow pump. The problem that an existing lubricationliquid flow pump is high in flow, cannot liquid intermittently and cannot achieve variable flow are solved. According to the scheme, the high-temperature-resistant minisize adjustable plunger-type lubrication flow pump comprises a pump body, a piston rod is arranged in the pump body, a special-shaped turbine is fixedly arranged at the upper end of the piston rod in a sleeving mode, a worm penetrates through the special-shaped turbine, a pump body is provided with an oil inlet and an oil outlet as well as a pump cover, an ejector pin is supported on the pump cover, and the piston rod is provided with a horizontal oil guide channel and a vertical oil guide channel. The high-temperature-resistant minisize adjustable plunger-type lubrication flow pump has the advantages that 1, the end face ofthe special-shaped turbine is matched with the ejector pin and is further matched with the worm through helical teeth, rotaton and axial piston movement are both achieved, and pump liquid is decelerated; 2, an adjusting shaft is used to achieve quantitative adjustment of the pumping amount of lubrication liquid; 3, the two oil outlets supply the liquid in turn, so that the lubrication liquid is supplied to an engine and other systems synchronously; and 4, by reasonably selecting materials, the problem of locking of a pairing friction pair under high temperature is solved, and the high-temperature operation reliability is improved.

Description

technical field [0001] The invention relates to a lubricating fluid flow pump, in particular to a high-temperature-resistant miniature adjustable plunger type lubricating flow pump. Background technique [0002] The lubricating fluid flow pump is a pump body that is generally applicable to the lubrication system of armored vehicle diesel engines. At present, most domestic pumps of this type use gear pumps, which have the disadvantages of large flow rate, inability to change variables, and inability to supply liquid intermittently. Some pumps are imported from Germany, but imported products have disadvantages such as high price and long delivery cycle. Therefore, with the rapid development of the country's vehicle power system, the demand for this type of lubrication pump is also increasing. In order to meet the growing needs of the engine lubrication system, the localization of this type of lubricating fluid flow pump is particularly urgent. Contents of the invention ...
