Abstract

The utility model discloses a kind of centrifugal pump automatic liquid sucker, the first valve is connected before the inlet tube of centrifugal pump, the other end of the first valve connects a threeway by pipeline, threeway one end is connected with the bottom of liquid container, the other end connects the second valve, and the other end of the second valve and pick-up tube to be connected with pipeline by another threeway and to insert the bottom of liquid storage tank, arrange two pores on the top of liquid container, one is connected with pick-up tube, and another is connected with reflow pipe by the 3rd valve.The beneficial effects of the utility model are, general industry self-priming centrifugal pump, due to long-time use, its sealability reduces, in centrifugal pump, liquid backflow is to liquid storage tank, and cause entering in centrifugal pump air and can not pumping liquid, this device is by increase high-order liquid container, can guarantee whenever be full of liquid in centrifugal pump, reach normal working.

Description

Centrifugal pump automatic liquid sucker
Technical field
The utility model belongs to metering equipment technical field, relates to a kind of centrifugal pump automatic liquid sucker.
Background technique
At present, general industry low level stores liquid, because liquid level is lower than centrifugal pump, all adopt self-priming centrifugal pump, liquid is pumped in measuring tank, specifically, because the storage pool storing sodium hypochlorite liquid is positioned at underground, and centrifugal pump is placed on the top of storage pool, therefore liquid can only be pumped in measuring tank by self-priming centrifugal pump, in this operation, cause leakage because the check valve sealing of self-priming centrifugal pump often goes wrong, cause centrifugal pump to dally, not only damage equipment, and bring great inconvenience to production.
Model utility content
The purpose of this utility model is to provide a kind of centrifugal pump automatic liquid sucker, a liquid container is increased before the import of centrifugal pump, the reflow pipe of measuring tank is received in this liquid container, return in liquid storage tank by liquid container, can guarantee that centrifugal pump does not dally like this.
The technological scheme that the utility model adopts is, a kind of centrifugal pump automatic liquid sucker, the first valve is connected before the inlet tube of centrifugal pump, the other end of the first valve connects a threeway by pipeline, threeway one end is connected with the bottom of liquid container, the other end connects the second valve, the other end of the second valve and pick-up tube to be connected with pipeline by another threeway and to insert the bottom of liquid storage tank, two pores are set on the top of liquid container, one is connected with pick-up tube, and another is connected with reflow pipe by the 3rd valve.
Feature of the present utility model is also, liquid container volume is greater than the pick-up tube of 2 times of volumes.
The bottom position of liquid container is higher than the inlet height of centrifugal pump.
The beneficial effects of the utility model are, general industry self-priming centrifugal pump, due to long-time use, its sealability reduces, in centrifugal pump, liquid backflow is to liquid storage tank, and cause entering in centrifugal pump air and can not pumping liquid, this device is by increase high-order liquid container, can guarantee whenever be full of liquid in centrifugal pump, reach normal working.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1. liquid container, 2. the first valve, 3. the second valve, 4. pick-up tube, 5. centrifugal pump, 6. liquid storage tank, 7. the 3rd valve, 8. reflow pipe.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The structure of a kind of centrifugal pump automatic liquid sucker of the utility model, as shown in Figure 1, the first valve 2 is connected before the inlet tube of centrifugal pump 5, the other end of the first valve 2 connects a threeway by pipeline, threeway one end is connected with the bottom of liquid container 1, the other end connects the second valve 3, the other end of the second valve 3 and pick-up tube 4 to be connected with pipeline by threeway and to insert the bottom of liquid storage tank 6, two pores are opened on the top of liquid container 1, one is connected with pick-up tube 4, and another is connected with reflow pipe 8 by the 3rd valve 7.
Liquid container 1 volume is greater than the pick-up tube 4 of 2 times of volumes, and the bottom position of liquid container 1 is higher than the inlet height of centrifugal pump 5.
In the utility model low level liquid storage tank, liquid pumps in manufacturing shop measuring tank by self-priming centrifugal pump, specifically a kind of device sodium hypochlorite liquid in storage pool below ground being pumped into measuring tank by self-priming centrifugal pump.Second valve 3 is discharging valve, is in normal off status, when the device is operated, close the 3rd valve 7, open the first valve 2, start centrifugal pump 5, liquid container 1 forms vacuum, in liquid storage tank 6, liquid self-absorbing is in liquid container 1, when measuring tank reaches measuring requirement, stop centrifugal pump 5 to work, measuring tank liquid exceedes metering section and is back in liquid container 1 by reflow pipe 8, now open the 3rd valve 7, close the first valve 2.
