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 lubricating liquid flow pump, specifically a high-temperature-resistant miniature adjustable plunger-type lubricating flow pump, which solves the problems of the existing lubricating liquid flow pumps with large flow rate, uninterrupted liquid supply and variable variables. The scheme includes a pump body, a pump There is a piston rod in the body, the upper end of the piston rod is covered with a special-shaped turbine, and a worm is also worn. There is an oil inlet and an oil outlet on the pump body. There is a pump cover on the pump body. There are horizontal oil guide grooves and vertical oil guide grooves. Advantages: 1. The end face of the special-shaped turbine cooperates with the ejector pin, and the helical gear cooperates with the worm to realize the rotation and axial piston movement at the same time, decelerating the pump fluid; 2. Quantitatively adjust the amount of lubricating fluid pumped through the adjustment shaft; 3. Two The four oil outlets supply liquid intermittently in turn, which is convenient for synchronously providing lubricating liquid for the engine and other systems; 4. Reasonable selection of materials can solve the problem of locking of paired friction pairs under high temperature and improve the reliability of high temperature work.

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 ...
