Abstract
The present invention relates to an adjustable flow vortex pump which is characterized in that a flow control device, a water inlet hole and a water outlet hole of which are respectively communicated with a water outlet and a water inlet of a vortex pump, is arranged on the vortex pump, and the water inlet hole and the water outlet hole can be mutually communicated or interrupted. The adjustment of operating conditions of the vortex pump can be realized by the present invention under the condition of not changing a pipeline characteristic curve, and power is economized as compared with a general throttling method for adjusting flow. A motor with small power can be used for driving the vortex pump, a starting current of the vortex pump is greatly reduced, and thus, the motor and a control element are protected.
Description
Affiliated field
The invention belongs to vane type oil pump, the adjustable peripheral pump of especially a kind of flow.
Background technique
The present both at home and abroad general peripheral pump of use of institute does not possess the regulatory function of flow.Adjusting to peripheral pump, generally adopt access flow controlling device on the output pipe of peripheral pump (being that flow limit method is regulated flow) to realize Flow-rate adjustment to peripheral pump, produce the peripheral pump series product of design etc. as domestic W, WG type peripheral pump, external Japanese Ni Keni company, himself does not possess flow regulating function.
As its prime mover, its rotating speed all is constant to peripheral pump by motor, and therefore, its performance also is changeless, and promptly it has fixing performance curve.When employing was installed flow regulator additional and changed the confluent of peripheral pump on pipeline, when the water yield diminished, the power of peripheral pump was to increase comparatively speaking, and this operation to peripheral pump is disadvantageous, is non-remunerative from the economic point of view.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, provide a kind of relatively simple for structure, the adjustable peripheral pump of the flow of internal adjustable flow.
The object of the present invention is achieved like this:
On the water intake of peripheral pump and water outlet position, install its water inlet and osculum respectively with the water outlet of peripheral pump and water intake is connected and this water inlet and osculum also can be interconnected or block flow regulator.
The impeller of the peripheral pump that the motor shaft of peripheral pump directly drives on it to be installed, this impeller can axially move freely on motor shaft; Flow regulator is made of valve body, valve pocket, spool, and be solidly installed by bolt and peripheral pump, its water inlet and osculum can be interconnected or block and its to be interconnected or to block what pass through be that spool is being realized by the displacement that thread engagement produced with valve pocket.
Advantage of the present invention and good effect are:
1. a kind of regulative mode brand-new to peripheral pump is provided, promptly increases flow regulating function in peripheral pump, the inlet/outlet of this flow regulator is communicated with respectively with the inlet/outlet of peripheral pump.When peripheral pump needs to change operating mode in pipeline, can implement adjusting to flow, peripheral pump is imported and exported connection, make a part of flow of peripheral pump outlet flow back to the peripheral pump import, like this, variation has just taken place in the flow that outputs in the pipeline.When adopting this regulating method, the valve opening on the pipeline is constant, thereby the characteristic curve of pipeline of peripheral pump also is constant.
2. the present invention can accomplish to drive peripheral pump with the motor of less power, and when implementing the variable adjusting, the inrush current of peripheral pump reduces greatly.
3. impeller can move freely on pump shaft in the axial direction, but the axial force that autobalance impeller pressure at both sides imbalance is caused.

Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described:
Referring to Fig. 1, Fig. 2, Fig. 3, peripheral pump is made of the pump housing 10, pump cover 6, pump bracket 7, blade 11, motor 9 is directly affixed by bolt with the pump bracket of peripheral pump, has omitted the supporting part and the parts such as parts that are connected with motor and coupling that are installed in the pump housing usually, has shortened the machine group length.Peripheral pump impeller in the pump housing is directly installed on the motor shaft 14, and this impeller can axially move freely on motor shaft, guarantee that impeller equates with axial clearance both sides between the pump housing, the pump cover, with the left and right cavity of balance impeller because of axial force that pressure imbalance was produced.Water-output flange 1 and water-in flange 4 are arranged on peripheral pump, and connection box for motor 8 is installed on the housing of motor.
By bolt 2 flow regulator 3 is installed in the water-in flange of peripheral pump and water-output flange bottom and (sees Fig. 3, Fig. 4, Fig. 5, Fig. 6), this flow regulator is by valve body, valve pocket 17 and spool 5 constitute, be shaped on water inlet 13 and osculum 15 in the valve body, this water inlet and osculum are communicated with the water outlet 12 of water-output flange and the water intake 16 of water-in flange respectively, water inlet and osculum can be interconnected and block, what its mode was passed through is to be set with valve pocket in the valve body of flow regulator, this valve pocket internal thread spool that has been connected with a joggle, spool can carry out displacement by thread engagement in valve pocket, the end of this spool in valve body is shaped on the water port, can when spool travel, realize the mutual perforation and the blocking-up of water inlet and osculum, therefore, spool also can be considered regulating handle.
Working principle of the present invention is:
The water inlet of flow regulator is communicated with the water outlet of peripheral pump, and osculum is communicated with the water intake of peripheral pump.When the flow of peripheral pump did not need to adjust, the spool swing offset was to the position of blocking-up water inlet and osculum.When flow need be adjusted, rotary spool connected water inlet and osculum.At this moment, a part of flow of peripheral pump water outlet flows back into osculum from the water inlet of flow regulator, enters the water intake of peripheral pump again from osculum, and like this, the flow that outputs on the pipeline has just reduced, and has realized the adjusting to piping flow.Flow-rate adjustment in this way, as can be seen, the valve opening on the pressure piping is constant, thereby the pump-unit characteristic curve of pipeline also is constant.Peripheral pump by coordinate shown in Figure 7 is regulated the operating mode schematic representation, can draw the superior technology efficiency of the present invention significantly:
Abscissa is flow Q, and y coordinate is power P and lift H; Curve P in the coordinate is a power curve, curve H is the peripheral pump head curve, curve K1 is the characteristic curve of pipeline after flow limit method is regulated flow, K2 is a characteristic curve of pipeline, when same traffic, the operation point of flow limit method is the A point, and operation point of the present invention is B point (the lift operation point of operation point of the present invention is the C point), then be respectively P1 and P2 from scheming to go up pairing performance number, the difference DELTA P of P1 and P2 is the power that adopts the present invention and flow limit method to save.
