[0002] General machinery uses a large number of rotating equipment to achieve the rotation or steering of the equipment itself and the transportation of materials or products. The rotating parts are generally equipped with bearings or sleeves, which require good lubrication. The quality of lubrication directly affects the life of bearings or sleeves, affecting the continuity of production and the benefits of the enterprise. Restricted by the reality of production continuity and the large number of rotating parts and lubrication points, the downtime is short and the manual refueling time cannot be guaranteed. Controlling the refueling amount according to time or refueling based on experience cannot ensure the lubrication effect. The refueling and lubrication of the post personnel cannot be effectively supervised and managed. The bearings are often damaged due to lack of oil, which brings great uncertainty to the long-term stable operation of the equipment, seriously restricting the production capacity and benefit growth.

DETAILED DESCRIPTION

[0014] The technical solution of the utility model is described below in conjunction with the accompanying drawings and implementation methods.

[0015] like Figure 1 As shown, a pressure-triggered reversing automatic oil replenishing system device comprises a glycerin pump (1), wherein an electric reversing valve (2) is provided on the side of the glycerin pump (1), and the lubricating oil passage is automatically switched according to a lubricating oil pressure signal and an electric signal; the electric reversing valve (2) is provided with a P port and a T port, and the glycerin pump (1) is connected to a one-way valve (3), a first stop valve (4) and the P port of the electric reversing valve (2) in sequence through a pipeline; a first pressure gauge (5) is provided on the side of the one-way valve (3), and the two are connected through a pipeline; and the glycerin pump (1) is connected to a second stop valve (6) and the T port of the electric reversing valve (2) through a pipeline.

[0016] The electric reversing valve (2) is respectively connected to the lubricating oil pipeline A and the lubricating oil pipeline B, and the lubricating oil pipeline A and the lubricating oil pipeline B are respectively connected to a plurality of glycerin two-line distributors (7), and the plurality of glycerin two-line distributors (7) are connected in parallel. The glycerin two-line distributor (3) is connected between the lubricating oil pipeline and the lubrication point, so as to realize progressive and continuous grease replenishment for the plurality of lubrication points.

[0017] The end of the lubricating oil A pipeline is connected to the first pressure relay (8), and a third stop valve (9) and a fourth stop valve (10) connected in parallel are provided between the two. The lubricating oil A pipeline is provided with a second pressure gauge (11).

[0018] The end of the lubricating oil B pipeline is connected to the second pressure relay (12), and a fifth stop valve (13) and a sixth stop valve (14) connected in parallel are provided between the two. The lubricating oil B pipeline is provided with a third pressure gauge (15).

[0019] A safety regulating valve (16) is also provided on the side of the glycerin pump (1), and both ends of the safety regulating valve (16) are respectively connected to the glycerin pump (1) through pipelines.

[0020] The utility model adopts a two-way oil supply of lubricating oil pipeline A and lubricating oil pipeline B. Lubricating grease is contained in a glycerin barrel. After the glycerin pump (1) is started, the lubricating grease in the barrel is injected into the lubricating oil pipeline. When the electric reversing valve (2) does not reverse, the lubricating oil flows from the P port of the electric reversing valve (2) into the A lubricating oil pipeline. The T port of the electric reversing valve (2) is connected to the B lubricating oil pipeline. The lubricating pressure of the A line gradually increases. The increased pressure drives the sliding plunger in the glycerin double-line distributor (7) to move, and squeezes the grease into each lubricating point (such as the bearing package). After the sliding plunger moves into place, the pressure of the lubricating oil pipeline A continues to increase, and the pressure of each lubricating point is consistent, and the amount of oil supplied is consistent. When the lubricating pressure of the lubricating oil pipeline A reaches a set value, such as 50 bar, the first pressure relay (8) sends a signal, and the pressure signal is converted into an electrical signal. The electrical signal controls the electric reversing valve (2) to change direction. After the change, the lubricating oil flows from the P port of the electric reversing valve (2) into the lubricating oil pipeline B. The T port of the electric reversing valve (2) is connected to the lubricating oil pipeline A. The lubricating pressure of the lubricating oil pipeline B gradually increases. The increased pressure drives the sliding plunger in the glycerin double-line distributor to move, squeezing grease to various lubrication points (such as the bearing package). The pressure in the lubricating oil pipeline A gradually decreases. After the sliding plunger moves into place, the pressure of the lubricating oil pipeline B continues to increase, and effective oil replenishment is implemented to various lubricating points. When the lubricating pressure of the lubricating oil pipeline B reaches a set value, such as 50 bar, the second pressure relay (12) sends a signal to control the electric reversing valve (2) to change direction again to replenish the lubricating oil pipeline A. The utility model can also replenish lubricating oil during continuous production, and the operation is simple, which greatly reduces the labor intensity of manual refueling of personnel on the job. The amount of oil replenished and the system working time can be set. Generally, the automatic oil replenishing system device of 10-40 distributors cycles once every 2 minutes for the first time, and then reverses once every 30 seconds. It can be suitable for greasing operations of rotating parts of all general mechanical equipment, specifically involving automatic oil replenishment of rotating parts of general machinery such as transport rollers, running rollers, spherical bearings, bushings and other equipment, automatic oiling and lubrication engineering operations, etc., and has good market application prospects.
