Abstract

The utility model relates to novel vacuum automatic water drawing equipment which comprises a vacuum water replenishing tank and is characterized in that an electromagnetic valve is connected between a vacuum cavity body at the upper part of the vacuum water replenishing tank and a water replenishing cavity body at the lower part thereof; liquid level switches arranged up and down are connected at the upper part of the vacuum cavity body which is connected with a water inlet pipeline; three paths of electromagnetic valves are connected in parallel on the water inlet pipeline; the vacuum cavity body is connected with an air pumping pipeline; a water ring vacuum pump, a moisture separator and an electromagnetic valve are connected in series on the air pumping pipeline; and the electromagnetic valve is further connected with the water replenishing cavity body at the lower part of the vacuum water replenishing tank. Compared with traditional water drawing equipment, the vacuum automatic water drawing equipment has the advantages of high automation degree, low installation cost, and small installation space. In addition, no fixing position is required in the installation of equipment and the equipment can be arranged and installed flexibly according to spot circumstances.

Description

The automatic diversion equipment of a kind of novel vacuum

Technical field

The utility model relates to a kind of diversion equipment, the automatic diversion equipment of particularly a kind of novel vacuum.

Background technique

Need in the complete water supply device no self-absorption function water pump is carried out diversion when starting, general employing is that single diversion jar connects as a water pump now, need manually to add water for this reason, and need connect the water source of moisturizing in addition, owing to need ad hoc staff to carry out moisturizing work, make the administration cost of pumping station rise, and a water pump connects the input cost that a diversion jar has increased equipment again, therefore demands designing a kind of novel automatic diversion equipment urgently to solve at present the problem to the diversion when the startup of no self-absorption function water pump.

Summary of the invention:

The purpose of this utility model is to solve in the prior art no self-absorption function water pump is carried out the existing the problems referred to above of diversion when starting, and provides a kind of novel vacuum automatic diversion equipment.The utility model designs the automatic diversion equipment of a kind of novel vacuum, comprise the vacuum feed jar, it is characterized in that: be connected to solenoid valve between the top vacuum cavity in the vacuum feed jar and the moisturizing cavity of bottom, the top of vacuum cavity is connected to the liquid-level switch of upper and lower settings, vacuum cavity is connected to inlet pipeline, on inlet pipeline and be connected to three-way electromagnetic valve, vacuum cavity is connected to exhaust pipe, be serially connected with water ring vaccum pump, moisture separator, solenoid valve on the exhaust pipe, solenoid valve connects the moisturizing cavity of vacuum feed jar bottom again.The utility model has the advantages that degree of changing into height, installation cost lack automatically, installing space is little than traditional water diversion apparatus, equipment is installed the requirement of no fixed position, can install according to the field condition flexible arrangement.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model,

Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.

Embodiment:

Comprise vacuum feed jar 5 among the figure, it is characterized in that: be connected to solenoid valve 4 between the top vacuum cavity in vacuum feed jar 5 and the moisturizing cavity of bottom, the top of vacuum cavity is connected to the liquid-level switch 10,9 of upper and lower settings, vacuum cavity is connected to inlet pipeline, on inlet pipeline and be connected to three-way

electromagnetic valve

6,7,8, vacuum cavity is connected to exhaust pipe, be serially connected with water ring vaccum pump 1, moisture separator 2, solenoid valve 3 on the exhaust pipe, solenoid valve 3 connects the moisturizing cavity of vacuum feed jar 1 bottom again.

Solenoid valve

6,7,8 are connected (pipeline between outlet non-return valve and the exit of pump) with the relief opening or the export pipeline of water pump, when equipment is worked for the first time, start water ring vaccum pump 1 by detecting liquid-level switch 9, (this moment, opened by solenoid valve 4 by aspiration vacuum replenisher tank 5 vacuum chambers for water ring vaccum pump 1, solenoid valve 3 cuts out, vacuum chamber is identical with the moisturizing chamber) air, air in pump water inlet road and the pump chamber is discharged behind moisture trap 2, water is through inlet pipeline, pump chamber, enter into the vacuum feed jar always, water ring vaccum pump 1 is out of service when liquid level arrives liquid-level switch 10 actions, after this liquid level is at liquid-level switch 9, pace up and down between 10, constantly guarantee that water pump satisfies priming level and requires (after equipment normally puts into operation, when being lower than liquid-level switch 9 and reaching the certain hour value as liquid level, then cut off the starting mode of pump power supply, and send warning) to control centre.During pump working, close corresponding relief opening or

outlet solenoid valve

6,7 or 8 automatically, then can break away from the monitoring of vacuum water diversion device, until out of service.Because water ring vaccum pump 1 operation needs certain water yield, so moisture trap 2 needs constantly to replenish the water yield of losing in service, in steam-water separator 2, add a liquid-level switch, by closing solenoid valve 4, opening solenoid valve 3, utilize water in the moisturizing chamber as the moisturizing water source, satisfy the water level requirement of moisture trap.The utility model can satisfy many water pump diversions of same pump house requirement simultaneously; When equipment maintains proper functioning, can start separate unit at any time or many water pumps put into operation, solve the diversion control of water pump under the automatic operation occasion; Equipment adopts control automatically, solves the problem that adopts single diversion jar to need frequent artificial recharge; Water ring vaccum pump moves the required moisturizing water yield and is adopted by equipment self that to draw water additional in the equipment, need not to connect in addition the moisturizing water source.

Claims

1. automatic diversion equipment of novel vacuum, comprise the vacuum feed jar, it is characterized in that: be connected to solenoid valve between the top vacuum cavity in the vacuum feed jar and the moisturizing cavity of bottom, the top of vacuum cavity is connected to the liquid-level switch of upper and lower settings, vacuum cavity is connected to inlet pipeline, on inlet pipeline and be connected to three-way electromagnetic valve, vacuum cavity is connected to exhaust pipe, be serially connected with water ring vaccum pump, moisture separator, solenoid valve on the exhaust pipe, solenoid valve connects the moisturizing cavity of vacuum feed jar bottom again.
