Abstract
The utility model discloses a manual high pressure butter gun plunger pump, which comprises a pump and a plunger. Wherein, the plunger on the pump is embedded with a cylinder sleeve the outer surface of which is axially provided with a plurality of gear-shaped diagonal grains; the cylinder sleeve is made from an iron group power metallurgy material, a copper material, a steel or a casting iron material. The utility model can effectively dispose the paradoxes that the application lifetime of the present product is relatively long while the product price is relatively high, or the product price is relatively low while the application lifetime is relatively short, and thus has the advantages of long application lifetime and low cost. The utility model is suitable for a plurality of manual high pressure butter guns.
Description
Technical field
The utility model relates to a kind of high pressure manual grease gun plunges pump body.
Background technique
In the plunger pump of existing high pressure manual grease gun, because friction is frequent between key job position plunger hole on the pump housing and the plunger, plunger hole weares and teares easily, therefore plunges pump body adopt generally that mechanical strength is higher, wear-resisting property preferably the zinc alloy material integral die-cast form, but because the price of zinc alloy material is higher, so the cost of product is also higher.Though also the someone adopts the lower aluminum alloy material of price to manufacture a product at present, to scheme to reduce the cost of product, its product but exists mechanical strength low, the shortcoming of wear-resisting property difference, and working life is shorter.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of cost long high pressure manual grease gun plunges pump body in lower but working life.
The purpose of this utility model realizes as follows: a kind of high pressure manual grease gun plunges pump body, comprise the pump housing, plunger, and be characterized in being inlaid with cylinder sleeve in the plunger hole on the pump housing.
Liner backs of the present utility model is provided with the plurality of tooth-shaped straight burr vertically.
Cylinder sleeve of the present utility model can adopt iron-base powder metallurgy material, copper material, steel or cast iron materials to make.
Need mechanical property preferably owing to have only in the plunges pump body with the frequent key position that rubs of plunger, after plunger hole was embedded in cylinder sleeve, the mechanical strength at this position and wear-resisting property all strengthened to some extent, therefore the working life that can improve product; Other position of plunges pump body then because less demanding to mechanical property can adopt the relatively low material of mechanical property to make, therefore can reduce production costs greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the radial section figure of cylinder sleeve of the present utility model (4).
Among the figure: 1 expresses the oil pipe attachment hole; The 2 expression pump housings; 3 expression connecting rod attachment holes; 4 expression cylinder sleeves; 5 expression plungers; 6 expression cylindrical shell connection mouths.
Embodiment
The utility model will be further described below with reference to accompanying drawing and by embodiment.
As shown in Figure 1 and Figure 2, high pressure manual grease gun plunges pump body has a pump housing 2 that adopts the aluminum alloy material die cast, there is an oil outlet tube attachment hole 1 pump housing 2 tops, there is a cylindrical shell connection mouth 6 its below, also has a connecting rod attachment hole 3 on the pump housing, be inlaid with a cylinder sleeve 4 in the plunger hole on the pump housing 2, a plunger 5 is arranged in the cylinder sleeve 4; In order to make cylinder sleeve 4 have higher mechanical strength and wear-resisting property preferably, cylinder sleeve 4 adopts iron-base powder metallurgy materials to make, and also can adopt other material such as copper material, steel or cast iron materials etc. to make; For cylinder sleeve 4 is inlayed when being cast into one with the pump housing 2 firmly, the outer surface of cylinder sleeve 4 is provided with the plurality of tooth-shaped straight burr vertically.Because be embedded with the cylinder sleeve 4 that adopts iron-base powder metallurgy material to make with the position of the frequent friction of plunger, the mechanical strength and the wear-resisting property at this position strengthen greatly, and greatly improved the working life of product.Owing to have only in the plunges pump body key position with the frequent friction of plunger need have mechanical property preferably, so the pump housing 2 adopted the less demanding aluminum alloy material of mechanical property made, and can reduce production cost of products greatly.
Claims (3)
1. a high pressure manual grease gun plunges pump body comprises the pump housing (2), plunger (5), it is characterized in that being inlaid with in the plunger hole on the pump housing (2) cylinder sleeve (4).
