Abstract
The utility model discloses an electric lubricating pump and belongs to the field of mechanical equipment lubricating technology. The electric lubricating pump comprises an oil tank assembly installed on a pump support and further comprises a motor reducing mechanism, a plunger piston auxiliary assembly, a deflation valve assembly, an overflow valve assembly and an electromagnetic unloading valve which are installed at the bottom of the oil tank assembly. A motor in the motor reducing mechanism drives a crankshaft and connecting rod mechanism to operate through two stages of gear assemblies so that a plunger piston in the plunger piston auxiliary assembly can reciprocate. The plunger piston auxiliary assembly is connected with an oil outlet and the oil outlet is provided with the deflation valve assembly, the overflow valve assembly and the electromagnetic unloading valve. With a little change, the lubricating pump can be applied in volumetric and progressive lubricating systems; the overflow valve is designed to be with fixed pressure, so that misoperation of users is prevented; and the deflation valve employs a pressing structure with small size, so that oil is prevented from being ejected directly when residual pressure exists in the system and the operators can be protected effectively.
Description
Technical field
The utility model relates to a kind of lubricant pump, and especially a kind of electronic lubricating pump that can be used in respectively positive displacement and laddering lubrication system, belongs to machinery lubrication technical field.
Background technique
The electronic lubricating pump of selling is in the market only applicable to positive displacement lubrication system or laddering lubrication system conventionally, and for the type of lubricant oil have relatively high expectations, conventionally can only be for drier oil or thin oil lubricant, therefore there is function singleness in this type of lubricant pump, need in actual use to match different lubricant pumps according to different occasions, can cause thus operator to have error in operation when operation is used, the problem such as in maintenance process Component are not general.
Model utility content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, proposes a kind of electronic lubricating pump, can be used in respectively positive displacement and laddering lubrication system, and convenient operation and post facility are safeguarded.
In order to solve above technical problem, the utility model provides a kind of electronic lubricating pump, the motor decelerating mechanism, trunk piston set assembly, bleed valve assembly, spill valve and the unloading electromagnetic valve that comprise the oil tank assembly being arranged on pump support and be arranged on described oil tank assembly bottom, motor in described motor decelerating mechanism drives connecting rod to move by two-stage gear assembly, and the plunger in described trunk piston set assembly is moved reciprocatingly; Described trunk piston set assembly is connected with oil outlet, and described bleed valve assembly, spill valve and unloading electromagnetic valve are installed on described oil outlet.
The utility model further limits technological scheme: aforesaid electronic lubricating pump, and described unloading electromagnetic valve adopts direct-acting type two-position two-way electromagnetic valve, and this solenoid valve has that volume is little, the feature of compact structure.
Aforesaid electronic lubricating pump, the bleed valve of described bleed valve assembly is press type structure, while avoiding there is residual voltage in system, fluid is faced ejection directly, thereby effectively protects operator.
Aforesaid electronic lubricating pump, the inside gearwheel of described motor decelerating mechanism is high strength polyoxymethylene gear, and installs yielding rubber pad additional at motor mounting plate place, and adopts PM self lubricated bearings at the axle head of transmission shaft, more than can effectively reduce noise.
Further, aforesaid electronic lubricating pump, described spill valve is fixation pressure formula structure, the accident of avoiding user to cause because of misoperation.
The beneficial effects of the utility model are: lubricant pump of the present utility model changes slightly, just can be used in respectively positive displacement and laddering lubrication system; And the compatible drier oil of energy and thin oil lubricant, trunk piston set adopts die casting aluminium and structure of mosaic, effectively alleviates deadweight; Delivery valve structure increases spring seat, avoids spring directly to contact steel ball, scratches its surface; Relief valve is designed to fixation pressure form, avoids user misoperation; Bleed valve adopts the small and exquisite press type structure of volume, and while avoiding there is residual voltage in system, fluid is faced ejection directly, thereby effectively protects operator.

Embodiment
A kind of electronic lubricating pump that the present embodiment provides, structure as shown in Figure 1, the motor decelerating mechanism 1, trunk piston set assembly 2, bleed valve assembly 3, spill valve 4 and the unloading electromagnetic valve 5 that comprise the oil tank assembly being arranged on pump support and be arranged on oil tank assembly 6 bottoms, unloading electromagnetic valve 5 adopts direct-acting type two-position two-way electromagnetic valve, motor in motor decelerating mechanism drives connecting rod to move by two-stage gear assembly, and the plunger in trunk piston set assembly is moved reciprocatingly; Trunk piston set assembly is connected with oil outlet, and bleed valve assembly, spill valve and unloading electromagnetic valve are installed on oil outlet, and the bleed valve of bleed valve assembly is press type structure, and while avoiding there is residual voltage in system, fluid is faced ejection directly, thereby effectively protects operator.
When the present embodiment is applied to laddering lubrication system: electrical power starts, by secondary gear assembly speed change, drive connecting rod action, plunger is moved reciprocatingly; While moving after plunger, owing to forming vacuum, oiling agent in oil tank can be sucked in cavity, when plunger advancement, plunger forms certain pressure by oiling agent and pumps and enter the stepwise type distributor in lubrication system by pipeline, impel distributor distribute lubricant to each lubricating point, form the effectively lubricating to equipment; When system pressure superpressure, relief valve off-load, can effectively protect each element in lubrication system to avoid damaging.
When the present embodiment is applied to quantitative lubrication system: when electrical power starts, unloading electromagnetic valve obtains the electric unloading channel of closing, motor, by secondary gear assembly speed change, drives connecting rod action, and plunger is moved reciprocatingly; While moving after plunger, owing to forming vacuum, oiling agent in oil tank can be sucked in cavity, when plunger advancement, plunger forms oiling agent that certain pressure pumps and enter the quantitative oil gun in lubrication system by pipeline, until system is in rated pressure; In the time of motor stopping, unloading electromagnetic valve dead electricity is opened unloading channel, sheds pressure in system, impels quantitative oil gun distribute lubricant to each lubricating point, forms the effectively lubricating to equipment, prepares for working for the second time of quantitative oil gun simultaneously; The rated pressure of system is controlled by relief valve, can effectively protect each element in lubrication system to avoid damaging.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
