Abstract
A kind of plunger pump grease seal, realizes the radial expansion of oil sealing by waveform.When oil sealing inter deterioration, oil sealing can realize reducing, and realizes oil sealing and contacts all the time with plunger, thus ensures plunger pump No leakage.The beneficial effects of the utility model are, structure is simple, and the wear-resistant time is long, easy to use, and novelty is strong, decreases the engineering time of plunger pump, well adds the working efficiency of plunger pump.
Description
Technical field
The utility model relates to a kind of plunger pump accessory, especially a kind of plunger pump grease seal.
Background technique
Plunger pump grease seal of today is all radial indeclinable, will reveal, the oil sealing that can only more renew after oil sealing inter deterioration.
Summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides that a kind of structure is simple, service time is long, thus reduces the oil sealing of maintenance frequency.
The utility model is achieved by the following technical solution: a kind of plunger pump grease seal, and its special way is that this oil sealing is radial wave shape wave, waveform expandable, if having wearing and tearing near the part of plunger, oil sealing then can inwardly reduce.
Plunger pump grease seal of the present utility model, is radial wave shape wave, can regards as and be coiled into round spring, envelope of draining the oil on plunger pump, makes oil sealing on plunger.In plunger pump using process, after the oil sealing wearing and tearing of plunger, oil sealing just can inwardly reduce, and ensures that oil sealing contacts all the time with plunger, thus ensures that plunger is not revealed.
Working principle of the present utility model is: by the waveform of oil sealing, oil sealing can radial direction be reduced, and when near plunger part wears, oil sealing then can reduce, thus realizes plunger pump No leakage.
The beneficial effects of the utility model are, structure is simple, and the wear-resistant time is long, easy to use, and novelty is strong, decreases the maintenance frequency of plunger pump, well adds the working efficiency of plunger pump.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
Fig. 1 is radial plane waveform oil sealing front view, Fig. 2 is radial plane waveform oil sealing plan view, Fig. 3 is sectional view in the waveform oil sealing of radial plane, Fig. 4 is radial tapered waveform oil sealing front view, Fig. 5 is radial tapered waveform oil sealing plan view, and Fig. 6 is sectional view in radial tapered waveform oil sealing.
Embodiment
Embodiment one: radial plane waveform oil sealing
Fig. 1 is radial plane waveform oil sealing front view, and Fig. 2 is radial plane waveform oil sealing plan view, and Fig. 3 is the middle sectional view of radial plane waveform oil sealing, and drawing oblique line place in middle sectional view is Cut-away section.Oil sealing is waveform as can be seen from Figure 1, has a cylindrical and an inner circle in Fig. 2, inner circle all the time with plunger contact, keep conveying liquid No leakage, can find out that this radial plane waveform oil sealing is radial plane from Fig. 3 midship section.Known from this three width figure, this radial plane waveform oil sealing can realize radial stretching by waveform, can realize radial expansion when oil sealing inter deterioration.
Embodiment two: radial tapered waveform oil sealing
Fig. 4 is radial tapered waveform oil sealing front view, and Fig. 5 is radial tapered waveform oil sealing plan view, and Fig. 6 is the middle sectional view of radial tapered waveform oil sealing, and drawing oblique line place in middle sectional view is Cut-away section.Oil sealing is waveform as can be seen from Figure 4, has a cylindrical and an inner circle in Fig. 5, inner circle all the time with plunger contact, keep conveying liquid No leakage, can find out that this radial tapered waveform oil sealing is radial tapered from Fig. 6 midship section.Known from this three width figure, this radial plane waveform oil sealing can realize radial stretching by waveform, can realize radial expansion when oil sealing inter deterioration.
Claims (2)
1. a plunger pump grease seal, is characterized in that: this oil sealing is radial wave shape wave.
2. plunger pump grease seal according to claim 1, is characterized in that: radial wave shape wave comprises radial plane waveform and radial tapered waveform.
