Abstract
The utility model relates to a vertical pipeline pump, in particular to an anti-freeze vertical pipeline pump capable of preventing a pump body from being frozen and cracking in the winter. The anti-freeze vertical pipeline pump comprises the pump body (1) and a power motor (2). A liquid inlet (3) and a liquid outlet (4) which are communicated with an inner cavity of the pump body are provided. A blowoff valve (6) is installed at and communicated with the lower end of the liquid outlet pipeline at the bottom of the pump body (1). The blowoff valve can be a manual stop valve, a check valve or a normally opened type magnetic valve or an electrically operated valve. In the cold winter weather, the blowoff valve is opened automatically or manually when the pump stops running, and residual liquid accumulated in the pump body is discharged, thereby effectively preventing the pump body from being frozen and cracking in the winter, facilitating saving of production cost and prolonging service life of the pipeline pump. The anti-freeze vertical pipeline pump is simple in structure, easy to perform, simple and convenient to install and use and low in cost.
Description
Technical field
The utility model relates to a kind of riser pump, particularly relates to a kind of riser pump that can prevent pump housing bursting by freezing in the winter time.
Background technique
Fields such as water, remote water delivery on industry and urban water supply and sewerage, tall building supercharging water feeding, gardens sprinkling irrigation, cooling tower, or with supercharging of changes in temperature water cycle and coordinative composition of equipments etc., usually use pipeline mounted pump, be mainly used in that pipeline pressurizes, the conveying of liquid material etc.Be divided into vertical and horizontal two kinds according to the mounting type pipeline mounted pump, because the design of riser pump structure is unique, the one, the turnover bore is identical; And be positioned on the same center line, can be installed among the pipeline as valve, compact appearance is attractive in appearance; Floor space is little, and building drops into low; The 2nd, the impeller of riser centrifugal pump is directly installed on the extension shaft of motor; Axial dimension is short, compact structure, and pump and motor bearings configuration are rationally; The radial and axial load that produces of ballast pump running effectively, thus guaranteed pump operate steadily, vibrate little, noise is low; Secondly structural feature has determined it to have the maintenance of installation and need not to tear open pipe-line system, advantage efficiently easy to maintenance, thereby be widely applied to every field.In fields such as metallurgy, chemical industry, weaving, papermaking, industrial continuity has determined that the riser pump might be throughout the year all at work.But because China is vast in territory, weather is complicated, various places four seasons temperature difference is very big, and present riser pump; Even quit work, still there is material to accumulate in the pump housing, like this to winter; Owing to expand with heat and contract with cold, be easy to pump housing bursting by freezing is caused the damage of equipment; The normal operation that influence is produced brings no small economic loss to enterprise.Usually the measure of taking at present is to increase the insulation measure in winter to the pump housing, and effect is not very desirable, can not tackle the problem at its root.
The model utility content
The utility model is not enough to existing technology, proposes a kind of riser pump with blowdown valve, and is simple in structure, easy to use, can reach winter to prevent pump housing bursting by freezing effect preferably.
The technological scheme that the utility model adopted:
A kind of antifreeze riser pump; Contain the pump housing (1) and power motor (2); Be communicated with said pump housing inner chamber and be provided with liquid-inlet (3) and liquid outlet (4), be communicated with an installation blowdown valve (6) with it in the liquid outlet pipeline lower end of the said pump housing (1) bottom.
Described antifreeze riser pump is drawn a straight length (5) in pump housing bottom liquid outlet conduit elbow through elbow (7), and blowdown valve (6) substantially horizontal is installed in the said straight length (5).
Described antifreeze riser pump, said blowdown valve (6) is a hand stop valve, said hand stop valve is ball valve or gate valve.
Described antifreeze riser pump, blowdown valve (6) is an one-way valve.
Described antifreeze riser pump; Blowdown valve (6) is an electronic or electromagnet cut off valve open in usual; Be provided with electronic in the power box on the said pump housing or the electromagnet cut off valve power adapter circuit; Said power adapter circuit input end connects power motor power input, the electronic or electromagnet cut off valve of power adapter circuit output terminal control connection.
The useful good effect of the utility model:
1. the antifreeze riser pump structure of the utility model is simple, implements and install and use easy, with low cost easily.When pump is out of service, open blowdown valve, raffinate in the pump is emitted, can prevent effectively winter from, to help saving production cost with pump housing bursting by freezing.
2. the antifreeze riser pump of the utility model; Blowdown valve is through adopting normally open solenoid valve or mortor operated valve; Solenoid valve or mortor operated valve while dead electricity when the pump outage is stopped using, blowdown valve recovers normally open, and the liquid that accumulates is wherein discharged automatically; Easy to usely save worry, unlikelyly cause device damage because forget.
