Abstract
Suction pumps on one body fluid of self-priming and machine sealing flushing, check device is installed at the pump intake of centrifugal pump, flushing water pipeline one end is located at the intracavitary of the mechanical seal of centrifugal pump, it fills pump line line one end and connects flushing water pipeline, it fills the pump line line other end and connects pump intake, it fills pump line line and is equipped with solenoid valve, liquid level sensor is installed on pump case, solenoid valve connects fluid level controller with liquid level sensor.Suction pumps on one body fluid of self-priming and machine sealing flushing of the utility model, and centrifugal pump is selected to improve as conveying main body, and operating cost is low, stable, solves the problems, such as that explosion-proof area includes the fluid conveying of admittedly high sludge-tank.
Description
Technical field
The utility model relates to convey the pump technical field of liquid.
Background technique
Mainly there are submerged pump, immersible pump, synchronous discharging-suction pump, self priming pump or centrifugal pump to the conveying of liquid in underground pond at present
Entrance adds faucet to add the modes such as water to convey by pipeline tapping.Many underground ponds belong to explosion-proof area, must satisfy using equipment
The requirement of explosion proof of DIIBT4, if using immersible pump, the inconvenience for becoming maintenance, using being just restricted.Submerged pump again because
There are security risks to be restricted for long axle bearing, if mediocre person expects that solid content is relatively more, impurity is more, and self priming pump is inhaled with synchronous row
Pump is easy blocking again, therefore needs a kind of conveying equipment for fluid substances for being not easy blocking and working on pond again.
Summary of the invention
In order to solve existing submerged pump, immersible pump, synchronous discharging-suction pump, the above problem existing for self priming pump or centrifugal pump, this
Utility model provides suction pump on a kind of self-priming and one body fluid of machine sealing flushing.
The utility model technical solution used for the above purpose is: suction on one body fluid of self-priming and machine sealing flushing
It pumps, check device is installed at the pump intake of centrifugal pump, flushing water pipeline one end is located at the intracavitary of the mechanical seal of centrifugal pump, fills pump
Pipeline one end connects flushing water pipeline, fills the pump line line other end and connects pump intake, fills pump line line and is equipped with solenoid valve, pacifies on pump case
Liquid level sensor is filled, solenoid valve connects fluid level controller with liquid level sensor.
The flushing water pipeline is equipped with valve.
The liquid level sensor is contactless liquid level sensor.
Suction pumps on one body fluid of self-priming and machine sealing flushing of the utility model, and centrifugal pump is selected to be changed as conveying main body
Into, operating cost is low, and it is stable, solve the problems, such as that explosion-proof area includes the fluid conveying of admittedly high sludge-tank.
Detailed description of the invention
Fig. 1 is suction pump configuration figure on one body fluid of the utility model self-priming and machine sealing flushing.
In figure: 1, pump intake, 2, check device, 3, centrifugal pump, 4, mechanical seal, 5, filling pump line line, 6, solenoid valve, 7, valve
Door, 8, external flushing water pipeline, 9, fluid level controller, 10, liquid level sensor.
Specific embodiment
Suction pump configuration on one body fluid of self-priming and machine sealing flushing of the utility model as shown in Figure 1, centrifugal pump 3 pump intake
Check device 2 is installed, 8 one end of flushing water pipeline is located at the intracavitary of the mechanical seal 4 of centrifugal pump 3, fills 5 one end of pump line line and connects at 1
Flushing water pipeline 8 is connect, flushing water pipeline 8 is equipped with valve 7, fills 5 other end of pump line line and connects pump intake 1, fills and set on pump line line 5
There is solenoid valve 6, contactless liquid level sensor 10 is installed on pump case, solenoid valve 6 and liquid level sensor 10 connect fluid level controller
9。
The utility model selects centrifugal pump to improve as conveying main body, adds check device, and benefit in inlet duct
With the external filling pump line line 5 of external flushing water pipeline 8 of pump mechanical sealing, use solenoid valve 11 as the control for the on-off for filling pump liquid
Component processed pumps intracorporal liquid level by the detection of liquid level sensor 10, the opening and closing of solenoid valve is controlled by fluid level controller,
Automatically pump is filled when reaching no liquid in pump chamber, pump chamber fills rear self-braking purpose, makes to obtain entrance after being centrifuged pump startup
Vacuum degree will material suck pump case in.
