Abstract
The utility model discloses a screw pump which comprises a pump body, a drive screw, a driven screw, a front cover, a rear cover, an oil suction port, an oil pressing port and working cavities, wherein the drive screw and the driven screw are arranged in the pump body, the oil suction port is arranged in the left side of the pump body, the oil pressing port is arranged in the right side of the pump body, the rear cover is arranged at the bottom of the pump body and connected with the working cavity one working cavity, and the front cover is arranged at the head part of the pump body and connected with the other working cavity. The screw pump provided by the utility model has the advantages of good suction performance, uniform continuous flow, small vibration and low noise.
Description
Technical field
The utility model relates to a kind of screw pump.
Background technique
The pump of being sold in the market, numerous in variety, but all exist suction performance poor mostly, the big and big such problem of Oscillation Amplitude of noise.
The model utility content
The model utility purpose: the purpose of the utility model is in order to solve the deficiency of existing technology, a kind of screw pump to be provided.
Technological scheme: in order to realize above purpose, the described a kind of screw pump of the utility model is characterized in that: comprise the pump housing, initiatively screw rod; Driven screw rod, protecgulum, bonnet, inlet port; Press hydraulic fluid port, active chamber, described active screw rod and driven screw rod are located in the pump housing, and described inlet port is located at pump housing left side; Described pressure hydraulic fluid port is located at pump housing right side, is covered on pump housing bottom after described and is connected with active chamber, is covered on pump housing head before described to connect in active chamber.
Carry out work in order to mesh better, described active screw rod is protruding screw rod, and described driven screw rod is recessed screw rod.
In order normally to carry out oil pressure, described active screw rod is parallel with driven screw rod.
In order to make pump housing better tightness, the sealing layer of described inlet port and pressure hydraulic fluid port is at least two-layer.
Better for the sealability of the pump housing, described protecgulum and bonnet are sealing cover.
Beneficial effect: suction performance is good, and flow is evenly continuous, vibrates for a short time, and noise is low.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein: 1. the pump housing, 2. screw rod initiatively, 3. driven screw rod, 4. protecgulum, 5. bonnet, 6. inlet port is 7. pressed hydraulic fluid port, 8. active chamber, 9. active chamber.
embodiment.
Further illustrate the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of screw pump is characterized in that: comprise the pump housing, initiatively screw rod; Driven screw rod, protecgulum, bonnet, inlet port; Press hydraulic fluid port, active chamber, described active screw rod and driven screw rod are located in the pump housing, and described inlet port is located at pump housing left side; Described pressure hydraulic fluid port is located at pump housing right side, is covered on pump housing bottom after described and is connected with active chamber, is covered on pump housing head before described to connect in active chamber, and described active screw rod is protruding screw rod; Described driven screw rod is recessed screw rod, and described active screw rod is parallel with driven screw rod, and the sealing layer of described inlet port and pressure hydraulic fluid port is at least two-layer, and described protecgulum and bonnet are sealing cover.
Utilize screw pump, accomplish oil suction and the process of pressing oil, initiatively screw rod 2 keeps good cooperating with the cylindrical that driven screw rod 3 forms with the corresponding cambered surface of the pump housing 1; When active screw rod 2 to right rotation, the rotation of direction that then the driven screw rod 3 of its both sides is just opposite with it thereupon, this moment initiatively between screw rod 2 and the driven screw rod 3 the seal operation chamber 8 of formation also move thereupon; Seal operation chamber 8 volumes on the left side increase thereupon; Therefore just from inlet port 7 oil suctions, and the volume in a rightmost seal operation chamber 9 reduces gradually, through pressing hydraulic fluid port 7 oil pressure is gone out; Screw pump is accomplished pump housing oil suction and the process of pressing oil through the initiatively motion of screw rod 2.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, its objective is to let to be familiar with the also enforcement according to this of content that these those skilled in the art can understand the utility model, can not limit the protection domain of the utility model with this.All equivalents or modifications of having done according to the utility model spirit all should be encompassed within the protection domain of the utility model.
