Abstract

The invention discloses a superposition type multi-point grease lubrication pump. A body component formed by superposing a plurality of bodies is installed on the bottom surface of an oil storage cylinder, each body is provided with a plurality of rows of subpumps in parallel, a plurality of common oil suction channel holes and a plurality of common power source channel holes are arranged in the superposition type body component, the common oil suction channel holes are communicated with the inner cavity of the oil storage cylinder, the common power source channel holes are communicated with an external power source on a body arranged at the lowest layer, each row of subpumps comprise a group of double-action pistons and two groups of grease pump units which are driven by the double-action pistons and are symmetrically arranged, via holes which are communicated with two common power source channel holes in the superposition type body component are arranged at motion stop points at both sides of the double-action pistons, compressed air or pressure oil as a power source drives the double-action pistons to reciprocate way passing through the channel holes on the bodies to enable oil pressure plungers of the grease pump units at the both sides connected with the compressed air or the pressure oil to finish the process of oil suction and exhaust in an alternating way and independently exhaust high pressure grease from a respective oil outlet through pressurization, thereby finishing grease supply to a lubrication point.

Description

technical field [0001] The invention relates to a multi-point grease lubricating pump, which belongs to a functional basic part in the technical field of lubrication, and is suitable for a pneumatic or hydraulic multi-point grease lubricating pump using compressed air or pressure oil as a power source. Background technique [0002] At present, the known multi-point grease lubrication pumps all use electric motors as the power source to drive each point pump to work through mechanical transmission; there are also pneumatic single-point grease lubrication pumps or hydraulic single-point grease lubrication pumps that use compressed air or pressure oil as the power source. Pump. And in many equipments, already equipped with hydraulic pressure or pneumatic system, when needing to adopt the grease lubricating pump that has a plurality of independent oil outlets, and when requiring to utilize existing power system, then existing known product but can't satisfy the requirement. Aft...
