Lubricating device with pneumatic tire pressure oil tank

Abstract

The invention relates to a lubricating device with a pneumatic tire pressure oil tank, which comprises a lubricating pump shell, a power assembly, a lubricating pump, a cylindrical oil tank, a piston and a sealing ring, wherein the power assembly and the lubricating pump driven by the power assembly are arranged on the lubricating pump shell; the cylindrical oil tank is fixedly connected with the lubricating pump shell; the piston divides the cylindrical oil tank into an oil tank upper cavity A and an oil tank lower cavity B which are sealed mutually by the sealing ring; and an oil inlet C of the lubricating pump is communicated with the oil tank lower cavity B for storing oil. The lubricating device is characterized in that: a sealing pneumatic tire is arranged in the oil tank upper cavity A and is connected with an inflating valve extending out of the upper part of the oil tank upper cavity A. Due to the adoption of the structure, an oil inlet mode of oil suction from the oil inlet of the lubricating pump can be changed into an oil inlet mode of powerful oil press-in to ensure that the oil enters from the oil inlet of the lubricating pump fully, so the oil pumping capacity of the lubricating device is higher than that of the conventional product, high-viscosity oil still can be pumped at a certain low temperature and under low air pressure, and the application range is expanded simultaneously.

Description

technical field [0001] The invention belongs to the technical field of lubrication and relates to a lubrication device, in particular to a lubrication device with a pneumatic tire pressure oil tank. Background technique [0002] At present, centralized grease lubrication technology has been widely used in our country. It can implement timing and quantitative automatic oil injection to each lubrication point when the mechanical equipment is running. This type of device overcomes the shortcomings of manual oiling. For example, LINCOLN series plunger pump devices, VOGEL series plunger pump devices, Ningbo Sanlang's KFP gear pump devices, etc. have been sold on the market. Most of these lubrication pump devices use cylindrical oil tanks, and the upper chamber of the oil tanks is directly connected to the atmosphere. In the same way, air pressure is equal to atmospheric pressure. These lubricating pump devices respectively adopt various auxiliary lubricating pump oil inlet stru...

Problems solved by technology

However, for mechanical equipment that requires high-viscosity grease and normal operation in winter low-temperature environments or low-pressure environments, the pumping capacity of these current lubricating pump devices is difficult to meet

The reason is that the structure of the oil inlet of the various auxiliary lubricating pumps mentioned above has a limited effect, and the lubricating pump mainly relies on the limited vacuum suction generated by itself during operation to suck the lubricating grease. The oil inlet cannot effectively absorb a sufficient amount of grease or even evacuate it

At present, for most mechanical equipment that requires the use of high-viscosity grease and operates in a low-temperature environment or low-pressure environment in winter, it is either lubricated by a manual grease gun, or the use of low-viscosity grease is required to reduce friction pair lubrication, which will It will reduce the performance of the machine, affect the operation, and cause early damage to the machine
