Description
Under technical field the present invention relates to a kind of energy recycle device, especially a kind of self-regulating multistage direct-coupled hydraulic recovery turbine that is applicable in the industries such as oil, chemical industry the remaining liq energy recovery.
Background technique is present, conventional both at home and abroad hydraulic recovery turbine adopts following several structures usually: motor, the direct linkage structure of clutch are set between pump and hydraulic recovery turbine, the turbine engine regenerative power of this structure can not drive the driven equipment pump fully, exist supplementary equipment more, the investment problem of higher.Between pump and hydraulic recovery turbine, electric motor structure is set,, has increased the operation easier when system moves, also reduced the Security and the reliability of device though this structure has reduced cost of investment.The direct linkage structure of pump and hydraulic recovery turbine, the regenerative power of this structure turbine engine can drive the driven equipment pump fully, this structure is by the turbine engine direct-driven pump, cancelled supplementary equipment, reduced cost of investment greatly, but owing to be the direct connection structure, to the quite high requirement of design proposition of turbine engine, the operation when also being unfavorable for simultaneously on-the-spot the operation.
Summary of the invention the object of the invention provides a kind of self-regulating multistage direct-coupled hydraulic recovery turbine that has from conditioning function, little investment.
For achieving the above object, self-regulating multistage direct-coupled hydraulic recovery turbine of the present invention comprises centrifugal pump, multistage turbine, coupling, wherein between centrifugal pump and multistage turbine,, coupling axially is connected by being installed, set up a self-regulation pipeline that modulating valve is installed in the turbine engine, one end of this self-regulation pipeline is connected with turbine engine tap stage casing, and the other end is connected with the turbine engine Spit Section; The running shaft of turbine engine is attached with speed probe.
Adopt said structure, require to change the flow of the diverse location impeller of flowing through, adjust deviation, the stable normal operation of assurance equipment by the position that changes the tap stage casing according to on-the-spot actual production.Be installed in the partial discharge that the modulating valve in the pipeline between tap stage casing and the Spit Section is regulated the turbine engine of flowing through by adjusting, realize adjusting the regenerative power of turbine engine.Promptly adjust the working speed of turbine unit, satisfied pump performance requirement under the different operating modes, accurately located easy-to-operat.By speed probe is installed the running rotating speed of entire equipment is monitored constantly,, then send alarm signal, carry out chain reaction, realize automatic monitoring and control if rotating speed surpasses specified value.
Advantage of the present invention is: have simple in structure, investment, operating cost is less, can guarantee device security, stable operation, is convenient to accurate adjustment, production operation is simple.
Description of drawings Fig. 1 is the overall structure schematic representation of self-regulating multistage direct-coupled hydraulic recovery turbine of the present invention.
Fig. 2 is self-regulating multistage direct-coupled hydraulic recovery turbine application system figure of the present invention.
Embodiment is described further self-regulating multistage direct-coupled hydraulic recovery turbine of the present invention below in conjunction with accompanying drawing:
As shown in Figure 1, self-regulating multistage direct-coupled hydraulic recovery turbine of the present invention, be made up of parts such as multistage centrifugal pump 1, multistage turbine 2, coupling 3, wherein multistage centrifugal pump constitutes in axial direction being socketed in pump shaft 1-1 both sides by parts such as sealed member 1-2, suction casing 1-3, impeller 1-4, stator 1-5, stage casing 1-6, Spit Section 1-7, balanced controls 1-8.Multistage turbine constitutes in axial direction being socketed in rotating shaft 2-9 both sides by parts such as sealed member 2-1, tap stage casing 2-2, Spit Section 2-3, stator 2-4, stage casing 2-5, impeller 2-6, suction casing 2-7, balanced controls 2-8.Between multistage centrifugal pump and multistage turbine,, coupling axially is connected by being installed, increase by one is equipped with the self-regulation pipeline 2-10 of modulating valve 4 in the turbine engine, one end of this self-regulation pipeline is connected with turbine engine tap stage casing 2-2, and the other end is connected with turbine engine Spit Section 2-3; Be attached with the electronic type speed probe at the running shaft 2-9 of turbine engine end.
Show as Fig. 2, the present invention adopts pump 1 and multistage turbine 2 by coupling 3 direct linkage structures, and multistage turbine is connected by pipeline with external equipment liquid level indicator 5, high-voltage device 6, reduction valve 7, inlet throttle valve 8, separating ranges 9, bypass 10, low pressure direction 11 respectively.
After adopting said structure, require to change the flow of the diverse location impeller of flowing through, adjust deviation, the stable normal operation of assurance equipment by the position that changes the tap stage casing according to on-the-spot actual production.Be installed in the partial discharge that the modulating valve in the pipeline between tap stage casing and the Spit Section is regulated the turbine engine of flowing through by adjusting, realize adjusting the regenerative power of turbine engine.Promptly adjust the working speed of turbine unit, satisfied pump performance requirement under the different operating modes, accurately located easy-to-operat.Monitor constantly by the running rotating speed that the speed probe countershaft is installed,, then send alarm signal, carry out chain reaction, realize automatic monitoring and control if rotating speed surpasses specified value.
By verification experimental verification can be the Conversion of energy of highly pressurised liquid mechanical energy, realizes energy recovery.Simple in structure, little investment that the present invention has can guarantee device security, stable operation, is convenient to accurate adjustment, and is simple to operate.
