Abstract

The utility model relates to a screw type self-priming high pressure water pump, which comprises a motor, an eccentric pump head, a pump body and a screw assembly, wherein a one-way valve is installed on the joint of the eccentric pump head and a suction inlet water nozzle, the bolt gum cover is pressed on the pump body by the flange surface of the eccentric pump head, then is directly connected on a large connection through a screw to be fastened, a large O-shaped ring is arranged on the joint of the large connection and the pump body, the screw holes of the eccentric pump head and the pump body are respectively sealed with allotype rubber rings, the large connection is fixed on the motor, the main shaft of the motor is connected with the bolt of the screw assembly through a universal flexible connector. The screw type self-priming high pressure water pump has the characteristics of simple structure, small volume, low energy consumption, low production cost and convenient maintenance.

Description

Screw type self-priming high-pressure water pump

Technical field

The utility model relates to a kind of self-priming clean waterpump, specifically is a kind of screw type self-priming high-pressure water pump.

Background technique

The common people be unable to do without water in daily life, in short supply when the raising of living condition and water source, be not suitable for deep-well water intaking and high-order water supply in water pump suction journey commonly used and lift at present, as supply water when highly needing 50M, send with high powered water pump or many water pumps, the cost height, construction is complicated, energy consumption is big.

The model utility content

The utility model provides the screw type self-priming high-pressure water pump of an efficient energy-saving, solved the problem of inhaling journey and lift, inhale the journey vertical height and surpass 9M, lift surpasses 80M, send water under the condition of sustained height, this pump successively electricity about 1/3rd, and have simple in structure, volume is little, low energy consumption, low cost of manufacture, characteristics easy to maintenance.

The utility model is realized like this:

A kind of screw type self-priming high-pressure water pump, comprise motor, eccentric pump head, the pump housing and screw rod assembly, it is characterized in that: described eccentric pump head is chewed the joint with suction saliva one on one-way valve is housed, eccentric driven pump head flange face is pressed in the screw rod gum cover of screw rod assembly on the pump housing, directly going here and there to Dalian by string heart screw then connects fastening, the big connection with pump housing junction point is provided with big O type circle, and the string heart screw of the eccentric pump head and the pump housing respectively has special-shaped seal with elastometic washer; The big connection is connected on the motor, and electric machine main shaft connects by universal soft connecing with the screw rod of screw rod assembly.

Working principle of the present utility model is: if screw rod joint square is 36MM, the joint square of screw rod gum cover should be 72MM, it realizes work by joint square difference, when electric motor starting turns round, by the moving screw rod run-in synchronism of universal soft tape splicing, because of the existence of the joint square difference of screw rod and screw rod gum cover is arranged, screw rod is whenever goed around in eccentric operating when screw rod rotates, produced the space of joint square difference, water just sucks the space, when screw rod forwards the space to, water is pushed inwards, because of screw rod and screw rod gum cover have higher quality of fit, so just reach the purpose of self-priming high pressure, can make and inhale journey more than 9M, lift can surpass more than the 80M; Come in addition practically by the string heart screw pump housing to be connected Dalian and to connect, simple in structure, connect reliable.

Description of drawings

Fig. 1, the utility model structural representation.

Embodiment

As shown in Figure 1, motor 1 end face is provided with big connection, on motor 1 output shaft mechanical sealing element is housed, output shaft and screw rod 11 softly connect 6 and are connected by universal, the pump housing 3 is contained in the big connection 2, the mating face is provided with big O type circle 7, eccentric pump head 4 is pressed in screw rod gum cover 5 on the pump housing 3 end faces, with six roots of sensation string heart screw 8 with to be connected greatly 2 fastening, on the string heart screw of eccentric pump head 4 and the pump housing 3 special-shaped rubber ring 9 is housed respectively, has guaranteed the sealing when high-pressure work, suck saliva and chew 10 and one-way valve 12 is housed with the junction point of eccentric pump head 4, prevent from when the motor stall, to be sent water to pour the pond into, add water plug screw 13 and add the usefulness that water screw 14 is used for water filling under the pump housing 3 interior anhydrous situations, will screw on adding water plug screw 13 after the pump housing 3 interior fills with water, drain screw 15 is used for temperature and crosses when hanging down, water pump not the time spent water in the pump is bled off, prevent a pump housing 3 bursting by freezing.

Should install suction sleeve and outlet pipe before use, to add water plug screw 13 then turns on, twist after in the pump housing 3, filling with clear water and go back, connecting the power initiation water pump again gets final product, screw rod 11 high speed rotating in screw rod gum cover 5 when motor rotation, joint square difference space closure is sent the outlet pipe interface with water, because of screw rod 11 and screw rod gum cover 5 have higher quality of fit, reaches the high-lift requirement of high suction depth; The utility model fluent form, elegant in appearance, simple in structure, easy to maintenance.

Claims

1. screw type self-priming high-pressure water pump, comprise motor, eccentric pump head, the pump housing and screw rod assembly, it is characterized in that: described eccentric pump head is chewed the joint with suction saliva one on one-way valve is housed, eccentric driven pump head flange face is pressed in the screw rod gum cover of screw rod assembly on the pump housing, directly going here and there to Dalian by string heart screw then connects fastening, the big connection is connected on the motor, and electric machine main shaft connects by universal soft connecing with the screw rod of screw rod assembly.

2. a kind of screw type self-priming high-pressure water pump as claimed in claim 1 is characterized in that: described big connection and pump housing junction point are provided with big O type circle, and the string heart screw of the eccentric pump head and the pump housing respectively has special-shaped seal with elastometic washer.
