Abstract
The invention relates to a water pump self-suction device which comprises a bottom plate connected with a pump body; the bottom plate is provided with a gas-water mixing tee pipe; the front end of the tee pipe is provided with a gas-water mixing outlet; a side hole in the middle of the tee pipe is provided with a water pipe connector which is communicated with the water pump body through a pipe; the water pipe connector is provided with an electromagnetic valve A; the rear end of the tee pipe is connected with one end of a gas pipe connector; the other end of the gas pipe connector is provided with a compressed air inlet which is connected with a gas source; a side hole of the gas pipe connector is provided with an electromagnetic valve B; and the electromagnetic valve A and the electromagnetic valve B are respectively connected with a binding post by a lead. When a water pump starts to work, the self-suction device firstly starts to work, the compressed air inlet is communicated with the gas source which is connected with a venturi device through the electromagnetic valve B and the electromagnetic valve A and is sprayed out at high speed from the gas-water mixing outlet, so that negative pressure is generated at an outlet of the tee pipe and is used for sucking the gas and liquid in the water pump and a water inlet pipe. When the air in the water pump body is exhausted, a main motor of the water pump is started to work, the self-suction device is switched off, and the electromagnetic valve A and the electromagnetic valve B are closed.
Description
Technical field
The present invention relates to water pump self-suction device, belong to the water pump field.
Background technique
Water pump comprises self-priming pump and two kinds of self-priming pumps not.Self-priming pump must not installed bottom valve in inlet pipeline, guarantees to be full of water in the inlet pipeline, and pump can proper functioning in the time of could guaranteeing to start once more.But there is the bottom valve water leakage phenomenon in the configuration bottom valve and increases the various disadvantages such as resistance that water sucks.And self-priming pump is owing to need certain water holding volume so volume is big, the cost increase.Because the efficient that makes pump that refluxes reduces, increase and answer gas-distributing motor power simultaneously, increase energy consumption.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, a kind of pumping line front end that is connected is provided, before water pump master electric motor starting, utilize Venturi principle; Pneumatically produces air blast and goes out, and takes away air in the pump simultaneously; Make in the pump with in the intake pipe and form negative pressure, in the water suction pump, though need not feed water for common water pump; Start laborsaving, easy to operate, water pump self-suction device low in energy consumption during work.
The technological scheme of water pump self-suction device of the present invention is: it is characterized in that comprising the base plate that connects the pump housing that air water mixing tee pipe is installed on the base plate, and the front end of three-way pipe is the air water mixed export; The side opening at three-way pipe middle part is installed water pipe adapter; Water pipe adapter is installed the solenoid valve first in the water pipe adapter in pipeline is communicated with water pump body, the rear end of three-way pipe connects of gas-tpe fitting; The other end of gas-tpe fitting is the compressed air inlet; The compressed air inlet connects source of the gas, and solenoid valve second is installed on the side opening of gas-tpe fitting, and solenoid valve first and the solenoid valve second lead of respectively hanging oneself is connected tenminal block.
Compared with present technology water pump self-suction device of the present invention before water pump is started working, starts working self-priming apparatus earlier; Source of the gas is connected in the compressed air inlet; Through solenoid valve second and solenoid valve first, Venturi sprays from air water mixed export high speed; Cause the three-way pipe outlet port to produce negative pressure, this negative pressure is used for aspirating gas and the liquid in water pump and the intake pipe.After having arranged air in the water pump body (the time length of self-priming is according to large and small, the long and short setting of pump water inlet), open water pump master machine operation, turn off self-priming apparatus, solenoid valve first, second is closed.
Water pump self-suction device of the present invention, the pressure of compressed air of its said source of the gas are 0.7-0.9MPa.Its said air water mixed export and compressed air inlet are on same center line.Its said three-way pipe is connected by screw thread with gas-tpe fitting.Screw thread makes three-way pipe be connected and easy accessibility with gas-tpe fitting.It is a copper tube joint in said water pipe adapter.
