Description
Technical field
The utility model relates to a kind of water pump component, and more particularly, it relates to a kind of hoghead assembly.
Background technique
Water pump is usually by driven by motor crankshaft rotating and then make the plunger be connected with bent axle do piston like motion, and plunger finally makes the electric energy conversion of motor be hydraulic energy to liquid acting.The part wherein socket-connected with plunger is called cylinder sleeve component, existing cylinder sleeve component generally includes plunger, cylinder sleeve, guide sleeve, pad and plunger sealing washer, and plunger is arranged between cylinder sleeve internal piston and cylinder sleeve and makes to form the normal work that good seal isolation ensures water pump between plunger two ends to carrying out fit sealing between plunger and cylinder sleeve by the plunger sealing washer of multilayer and pad.But after used a period of time due to sealing relatively good between plunger and cylinder sleeve, the lubricant oil of plunger at one end is made to be difficult to carry out good lubrication to the surface of contact between plunger and cylinder sleeve, plunger and cylinder sleeve will generate heat owing to lacking lubrication in a large number when relative movement, light then hinder crankshaft high-speed Effect of Rotation working efficiency, heavy then may cause cannot sealing between plunger two ends water pump inefficacy is scrapped.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of conveniently lubricates between plunger and cylinder sleeve, improves the hoghead assembly in water pump working life.
For achieving the above object, the utility model provides following technological scheme: a kind of hoghead assembly, comprise plunger, cylinder sleeve, guide sleeve, pad and plunger sealing washer, through hole is provided with along guide sleeve radial direction in the middle part of described guide sleeve, described cylinder sleeve is provided with for the oil dripping hole adding lubricant oil between plunger and cylinder sleeve in the position corresponding with through hole, described oil dripping hole and through hole are conducted, and are provided with some for stopping the cutoff board that fluid refluxes in described oil dripping hole.
By adopting technique scheme, lubricant oil is added in use in oil dripping hole, lubricant oil is by arriving plunger surface after oil dripping hole and through hole, when plunger carries out piston movement, lubricant oil is able to play lubrication effect between plunger and cylinder sleeve between surface of contact, prevent excessive wear between plunger and cylinder sleeve from improve the working life of water pump, and cutoff board can effectively prevent the lubricant oil injected from again flowing out from oil dripping hole along with the vigorous exercise of plunger, decrease the loss of lubricant oil, ensure that and can use for a long time after adding a lubricant oil.
The utility model is set to further: be provided with honeycomb duct between described oil dripping hole and through hole, described cutoff board is positioned at honeycomb duct, described cutoff board is oblique setting from oil dripping hole to through hole, described cutoff board arranges along the setting direction of described honeycomb duct, and described adjacent cutoff board is arranged in opposite directions and two cutoff boards are overlapped relative to the projection of the direction of axis line along honeycomb duct of the other end be connected with honeycomb duct inwall.
By adopting technique scheme, ensure that lubricant oil can lubricate to through hole from oil dripping hole along cutoff board, because adjacent two pieces of cutoff boards have blocked honeycomb duct completely, so when plunger motion, lubricant oil can't flow out in honeycomb duct, this structure is simple, convenient production, and can well prevent running off from oil dripping hole of lubricant oil.
The utility model is set to further: described oil dripping hole is greater than the level height of oil dripping hole at cylinder sleeve inner opposite end opening in the level height of cylinder sleeve lateral ends opening.
By adopting technique scheme, make lubricant oil can be poured into the effect in through hole, plunger being produced to oil sealing, only need determine to have in through hole the lubrication that lubricant oil can ensure between plunger and cylinder sleeve in the daily lubricated maintenance of plunger, simplify the lubricated maintenance process to plunger and cylinder sleeve.
The utility model is set to further: described through hole is greater than the diameter in the middle part of through hole at the side end face diameter near plunger.
By adopting technique scheme, increasing the area of contact of lubricant oil and plunger, improve lubrication effect.
Described through hole is greater than the diameter in the middle part of through hole at the side end face diameter near cylinder sleeve.
By adopt technique scheme, reduce cylinder sleeve make time for the required precision of offering oil dripping hole, be convenient to process oil dripping hole on cylinder sleeve, oil dripping hole connected with through hole convenient.

Embodiment
Referring to figs. 1 through Fig. 2, the utility model hoghead Assemblies Example is described further.
A kind of hoghead assembly, comprise plunger 1, cylinder sleeve 2, guide sleeve 3, pad 4 and plunger sealing washer 5, through hole 6 is provided with along guide sleeve 3 radial direction in the middle part of described guide sleeve 3, described cylinder sleeve 2 is provided with for the oil dripping hole 7 adding lubricant oil between plunger 1 and cylinder sleeve 2 in the position corresponding with through hole 6, described oil dripping hole 7 is conducted with through hole 6.Lubricant oil is added in use in oil dripping hole 7, lubricant oil is by arriving plunger 1 surface after oil dripping hole 7 and through hole 6, when plunger 1 carries out piston movement, lubricant oil is able to play lubrication effect between plunger 1 and cylinder sleeve 2 between surface of contact, prevents excessive wear between plunger 1 and cylinder sleeve 2 from improve the working life of water pump.
Honeycomb duct 9 is provided with between described oil dripping hole 7 and through hole 6, described cutoff board 8 is positioned at honeycomb duct 9, described cutoff board 8 is oblique setting from oil dripping hole 7 to through hole 6, described cutoff board 8 arranges along the setting direction of described honeycomb duct 9, and described adjacent cutoff board 8 is arranged in opposite directions and two cutoff boards 8 are overlapped relative to the projection of the direction of axis line along honeycomb duct 9 of the other end be connected with honeycomb duct 9 inwall.
Ensure that lubricant oil can lubricate from oil dripping hole 7 to through hole 6 along cutoff board 8, because adjacent two pieces of cutoff boards 8 have blocked honeycomb duct 9 completely, so when plunger motion, lubricant oil can't flow out in honeycomb duct 9, this structure is simple, convenient production, and running off from oil dripping hole 7 of lubricant oil can well be prevented.
