Abstract
The utility model provides a new technology for sealing a water pump, which is characterized in that a framework type rubber oil seal is pressed on a water pump shaft, and the middle of the framework type rubber oil sealing device is provided with a lubricating grease chamber. The lubricating grease chamber is communicated with a screw plug, a piston, an oil cup and an oil channel on a water pump seat. The utility model has simple structure, low cost, small power and long lifespan, and overcomes the disadvantages that the mechanical seal in prior art is complicated in structure, is short in service lifespan, and is suitable for various water pumps.
Description
The utility model is the new technology that belongs to the water pump packing structure
In prior art, mechanical seal and packing_seal are adopted in the sealing of water pump mostly.The mechanical seal structure compactness, but complicated, required precision is high, manufacture cost is high; Packing_seal is simple in structure, but maintenance bothers, frictional loss is big.Their common feature: working life is short, adorns the time spent on internal combustion locomotive, and less than three months is with regard to seal failure sometimes, causes machine to break, face that to repair fault more.
The purpose of this utility model is: a kind of water pump packing new structure is provided, its simple in structure, low cost of manufacture, the few and long service life of power consumption is applicable to various water pump packings usefulness, if be contained on the internal-combustion engine vehicle water pump, can guarantee 300,000 kilometers of safe operations (about more than a year)
The water-pump grease formula sealing configuration that the utility model provides, be designed to following structure: lean on the water pump vane place at water pump spindle, the steel axle sleeve is housed, on axle sleeve, press-fit skeleton rubber seal, grease pocket is arranged in the middle of skeleton rubber seal, grease pocket communicates with plug screw, piston, lubricating cup, oil duct on being contained in the water pump seat, to keep the supply of lubricating grease.
The utility model compared with the prior art because Sealing is rubber material, the absorbing performance is good and cost is low, adopts the working life of lubricating grease assurance rubber seal on the structure and reduces friction and power consumption.Skeleton rubber seal is fitted on the axle sleeve to be changed conveniently, can protect water pump spindle again, thus simple in structure than prior art, the cost low power consumption is little, economic and social benefit is remarkable.
The lubricating grease formula sealing configuration of accompanying drawing 1 water pump
An embodiment of the lubricating grease formula sealing configuration of the utility model water pump; as shown in Figure 1: water pump spiral case (6) and water pump vane (7) are installed on the water pump spindle (11) by water pump seat (5); locate to be equipped with steel axle sleeve (9) at water pump spindle (11) by water pump vane (7), not only protected water pump spindle but also be convenient to maintenance.On axle sleeve (9), press-fit skeleton rubber seal (8), in the middle of skeleton rubber seal (8) is grease pocket (10), grease pocket (10) communicates with plug screw (3) piston (4) oil duct (2) lubricating cup (1) on being contained in pump seat, to guarantee the needs of lubricated skeleton rubber seal (8).
When pump working, the high pressure water of outlet enters the A chamber, also enters A simultaneously
1And A
2The chamber, the lubricating oil pressure and the A of grease pocket (10)
1, A
2The chamber hydraulic balance, thus the friction that piston (4) moves reduced, reliable operation, the lubricating grease in the grease pocket (10) is constantly replenished through oil duct (2) by lubricating cup (1), and makes grease pocket keep certain lubricating oil pressure by piston (4).
The actual utilization shows: the lubricating grease type seal structure of the utility model water pump is simple, low cost of manufacture, and power consumption is little, and the life-span is long, reaches the expected effect of design fully, and more former sealing prolongs 4～5 times service life. Economic benefit and social benefit are remarkable.
Claims (1)
