Lubrication pumps for high viscosity lubricants

Abstract

The invention discloses a lubricating pump for high-viscosity lubricant. The lubricating pump comprises a pump body, a pump transmission device, a pump element, a motor, a cylinder cover and a cylinder body. The cylinder cover is disposed on the upper portion of the cylinder body. The motor is fixed on the cylinder cover through a connecting flange. The output shaft of the motor is connected with the upper end of the pump transmission device through a motor transmission sleeve. The lower end of the pump transmission device is fixedly connected with the pump body. The pump element is disposed at the bottom of the pump body. The outlet of the pump body is connected with a stainless steel pipe through a right-angle clamp sleeve connector. The other end of the stainless steel pipe is connected with a partition type right-angle clamp sleeve which is fixed on the cylinder cover through a connecting flange. The lubricating pump has the advantages that the lubricating pump is simple and novel in structure and convenient to operate, motor damage caused by the lubricant permeated into the motor can be avoided effectively, online oil refilling can be achieved by directly replacing the cylinder body, and the lubricant can be conveyed normally under low temperature.

Description

technical field [0001] The invention relates to the technical field of lubrication, in particular to a lubrication pump device that can be used for high-viscosity lubricants. Background technique [0002] High-viscosity lubricant refers to the kinematic viscosity of the oil at 40°C above 4000cSt or even 16000cSt. It is often used in the lubrication of open gears, slewing tracks of floating cranes and wire ropes. This kind of high-viscosity lubricant is characterized by high permeability and difficult pumping. It is generally used in manual operation at room temperature or below room temperature, but manual operation usually has randomness, uncertainty, and unevenness. Sexuality, high pollution and safety defects. [0003] The best way to work with high-viscosity lubricants should be pumping to avoid a series of problems caused by manual work. At present, the pump with the general dry oil lubrication structure in the lubrication system will leak over time, and the lubrican...

AI Technical Summary

Problems solved by technology

At present, the pump with the general dry oil lubrication structure in the lubrication system will leak over time, and the lubricant can easily penetrate into the motor, causing damage to the motor; the lubrication pump cannot deliver lubricant normally at low temperature conditions such as -20°C; At the same time, the online oil replenishment operation is difficult and the lubrication efficiency is low
