Abstract
An antiwear metering pump mainly comprises a pump body, a main shaft and a pump base, wherein the pump body is arranged on the pump base; a main shaft hole is arranged on the pump body; the main shaft is arranged in the main shaft hole; and an antiwear part is arranged between the main shaft and the pump base. Through the structure, the direct contact of the main shaft and the pump base can be avoided, and problems of wear pits caused thereby are prevented. The main shaft close to one end of the pump base can be of a convex structure and the antiwear part which is matched with the convex structure can be arranged on the convex structure for better realizing the connection between the main shaft and the antiwear part and further playing the role of the antiwear part. The antiwear metering pump has the advantages that through the antiwear part arranged between the main shaft and the pump base, the direct contact of the main shaft and the pump base can be avoided and the problems of wear pits caused thereby are prevented, therefore the sinking of the main shaft and the separating and slipping of a transmission connecting shaft on the main shaft and a transmission system of the metering pump are completely eradicated, and the production is ensured.
Description
Technical field
The utility model relates to a kind of pump, especially a kind of anti-wear metering pump.
Background technique
Present metering pump is when design, the main shaft of metering pump contacts with pump seat, as shown in Figure 1, continuous friction along with long operation, main shaft and pump seat, the wearing and tearing hole that has caused engendering on the pump seat of metering pump, thereby caused the sinking of main shaft, made the axle that is in transmission connection on the main shaft occur breaking away from the phenomenon of skidding, had a strong impact on the carrying out of production with the transmission system of metering pump.
Summary of the invention
The purpose of this utility model is a kind of anti-wear metering pump that prevents main shaft and pump seat friction that provides for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the anti-wear metering pump that the utility model is designed, it mainly comprises the pump housing, main shaft and pump seat, pump seat is provided with the pump housing, the pump housing is provided with spindle hole, be provided with main shaft in the spindle hole, be provided with anti-wear between described main shaft and the pump seat, by this structure, therefore can avoid main shaft to contact, prevent and the problems such as appearance wearing and tearing hole that cause with the direct of pump seat, for realize better main shaft with anti-wear between be connected, bring into play anti-wear effect biglyyer, described main shaft can be convex structure near an end of pump seat, can be provided with anti-wear that cooperates with it on the convex structure, and convex structure is meant that cross section is the structure of " protruding " font, its protruding stero shape can be cylindrical body, cuboids etc., such structure can make and form a kind of annexation that is nested between main shaft and anti-wear.In order to strengthen the abrasionproof effect, described anti-wear can be steel bushing.In order to dissolve better because of main shaft rotates the friction that causes, described anti-wear can be bearing, and bearing can play good fixed effect on the one hand, can realize being connected of rotatable parts and fixed component well again on the other hand.
The resulting anti-wear metering pump of the utility model, by the wear-out part of between main shaft and pump seat, setting up defences, can avoid main shaft to contact with the direct of pump seat, prevent the problems such as appearance wearing and tearing hole that therefore cause, production is guaranteed in the disengaging skidding that thereby the main shaft of having stopped therefore to cause sinks, the transmission system of be in transmission connection axle and metering pump on the main shaft occurs.
Description of drawings
Fig. 1 is the structural representation of existing metering pump;
Fig. 2 is the utility model embodiment 1 a structural representation;
Fig. 3 is the utility model embodiment 2 a structural representation;
Fig. 4 is the utility model embodiment 3 a structural representation.
Among the figure: the pump housing 1, main shaft 2, pump seat 3, wearing and tearing hole 4, anti-wear 5, steel bushing 51, bearing 52, convex structure 6.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 2, the described anti-wear metering pump of present embodiment, it mainly comprises the pump housing 1, main shaft 2 and pump seat 3, pump seat 3 is provided with the pump housing 1, and the pump housing 1 is provided with spindle hole, is provided with main shaft 2 in the spindle hole, be provided with anti-wear 5 between main shaft 2 and the pump seat 3, by this structure, can avoid main shaft 2 to contact with the direct of pump seat 3, prevent the problems such as appearance wearing and tearing hole 4 that therefore cause.
As shown in Figure 3, the described anti-wear metering pump of present embodiment, described main shaft 2 is a convex structure 6 near an end of pump seat 3, its protruding stero shape is a cylindrical body, convex structure 6 is provided with anti-wear 5 that cooperates with it, and anti-wear 5 is steel bushings 51.
As shown in Figure 4, the described anti-wear metering pump of present embodiment is to change bearing 52 into anti-wear 5 among the embodiment 2, and bearing 52 can play good fixed effect on the one hand, can realize being connected of rotatable parts and fixed component well again on the other hand.
