Abstract
Provided is a vertical type self-priming pump. The vertical type self-priming pump comprises a motor, a pump body and an impeller, wherein the motor is connected with a transmission mechanism which is connected with a rotating shaft on the pump body, the rotating shaft drives the impeller in the pump body to rotate, and centrifugal force of the impeller enables an inner cavity of the pump body to continuously generate negative pressure. The vertical type self-priming pump is characterized in that a vacuum pump is arranged on a self-priming pump, and an air-suction opening of the vacuum pump is respectively communicated with a water inlet and a water outlet of the vertical type self-priming pump through pipelines. The vertical type self-priming pump has no gas-liquid separation chamber of a big size and a vice-impeller dynamic sealing device. Compared with a common self-priming pump, energy consumption of the vertical type self-priming pump is decreased by more than 30%. The water inlet and the water outlet have no curved channel design, so that energy loss of flow in the curved channel is decreased, and efficiency is increased by more than 25%.
Description
Technical field:
The utility model relates to a kind of pump, relates in particular to the vertical self-sucking pump that a kind of chemical field uses.
Background technique:
At chemical field, the mechanical seal that existing vertical self-sucking pump adopts sub-propeller to replace Vintage Product to adopt usually, because pump in the running, sub-propeller and main impeller rotate together, thereby will inevitably consume certain available power, and the power of this additive decrementation can not convert effective liquid energy to, so will cause the total working decrease in efficiency of self-priming pump; In addition, when quitting work owing to vertical self-sucking pump, closing of exit of pump check valve must have certain lag time, thereby has all the time the problem of the interior leaked liquid of pump when shutting down, the environmental condition that this just has influence on the pump work place that is to say and can pollute working environment; At last, the pump of design also must configuration use solenoid valve like this, and from present use condition, electromagnetic valve work is unreliable, working life is short, has virtually increased the operation cost of enterprise.
Summary of the invention:
The utility model purpose is to provide the vertical self-sucking pump that a kind of energy consumption is low, efficient is high.
The purpose of this utility model is to realize like this, a kind of vertical self-sucking pump, comprise motor, the pump housing, impeller, described motor connection for transmission mechanism, driving mechanism connects the rotating shaft on the pump housing, and rotating shaft drives the wheel rotation in the pump housing, and the centrifugal force of impeller is so that pump housing inner chamber produces continuous negative pressure, it is characterized in that: be provided with vacuum pump on the self-priming pump, the intakeport of described vacuum pump communicates with vertical self-sucking pump water intake and water outlet respectively by pipeline.Described water intake is perpendicular to ground, and described water outlet is parallel to ground, and water intake, water outlet all adopt the straight way design.Be provided with the pressure transducer of monitoring pump housing chamber pressure in the pump housing described in the utility model, described pressure transducer links to each other with the control gear of control vacuum pump start and stop.
The utility model without volume larger gas-liquid separation chamber and dynamic sealing of auxiliary impeller device, can reduce more than 30% by the common self-priming pump of loss-rate; Intake-outlet designs without curve type, has reduced the energy loss of current in the bend process, and efficient improves more than 25%.
Description of drawings:
Fig. 1 is the utility model structural representation.
Among the figure 1, motor, 2, driving mechanism, 3, rotating shaft, 4, impeller, 5, the pump housing, 6, water intake, 7, intakeport, 8, pipeline 9, vacuum pump, 10, water outlet.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
A kind of vertical self-sucking pump, comprise motor 1, the pump housing 5, impeller 4, described motor 1 connection for transmission mechanism 2, the rotating shaft 3 that driving mechanism 2 connects on the pump housing 5, the impeller 4 that rotating shaft 3 drives in the pump housing 5 rotates, the centrifugal force of impeller 4 is characterized in that so that the pump housing 5 inner chambers produce continuous negative pressure: be provided with vacuum pump 9 on the self-priming pump, the intakeport 7 of described vacuum pump 9 communicates with water intake 6 and the water outlet 10 of vertical self-sucking pump respectively by pipeline 8.Be provided with the pressure transducer of the monitoring pump housing 5 chamber pressures in the pump housing 5 described in the utility model, described pressure transducer links to each other with the control gear of control vacuum pump 9 start and stop.During implementation, at first open vacuum pump, vacuum pump will extract the air in the pump housing 5, pressure in the pump housing 5 reaches reference value, sends signal by pressure transducer, and control gear stops vacuum pump 9 work, the pump housing 5 inner chambers reach vacuum state, start vertical self-sucking pump and just can draw water, avoided the operation of pouring water to the pump housing 5 inner chambers, saved the starting time of pump.
