Embodiment Construction

[0055] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0056] As a lubricating pump, the plunger pump mainly includes a pump unit and an oil storage barrel installed on the pump unit. The eccentric shaft driven by a motor passes through the pump unit and extends to the oil storage barrel. The eccentric shaft is used to drive the pump unit The plunger in the pump reciprocates linearly, pumps grease (lubricating oil or grease) from the oil storage barrel, and pumps the pumped grease out and supplies it to the required lubrication point through the oil pipe.

[0057] In the present invention, as figure 1 and image 3 As shown, the plunger pump mainly includes an eccentric shaft 3, a pump unit 1 and an oil storage bar...

Abstract

A piston pump, which comprises an eccentric shaft (3), a pump unit (1), and an oil tank arranged above the pump unit (1). The eccentric shaft (3) is extended through the pump unit (1) and connected to the oil tank (2). The pump unit (1) comprises an oil-drawing, oil-pressurizing part (11) and an oil-discharging part (12) detachably connected together. The eccentric shaft (3) is for use in driving the oil-drawing part (11) to pump oil from the oil tank (2) and to discharge the oil via the oil-discharging part (12). The piston pump has the advantages of a simple structure, low failure rate, and convenient disassembly for maintenance and repair.

Description

technical field [0001] The present invention relates to a lubricating pump, in particular to a plunger pump. Background technique [0002] At present, plunger pumps for lubrication systems are widely used. Generally, a plunger pump mainly includes a pump unit for oil suction and pressure, an oil storage tank for oil storage, and an eccentric shaft for driving the pump unit. The working principle of the plunger pump is to drive the plunger through the eccentric shaft, Make the plunger reciprocate linearly to realize the work of oil suction and pressure oil. In terms of structure, the current industry usually adopts an integrated pump unit, the spring-type plunger reciprocates, and the eccentric shaft drives the oil stirring plate in the oil storage tank through the connection of pins or keys, etc., resulting in a complex structure of the plunger pump. , processing is inconvenient, and prone to failure, and disassembly and maintenance are also extremely inconvenient.
