Abstract
The object of the present invention is to provide a kind of open type pitot tube pumps, fluid leakage problems caused by its object is to solve pump due to mechanical seal leakage, it is intracavitary in vane rotor to provide a kind of mechanical seal setting, the pump that mechanical seal allows to have certain leakage rate (leakage liquid is in rotor chamber) without influencing normal use.Open type pitot tube pump, is equipped with pump shaft in pump case with bearing bracket stand, and being fixedly connected on pump shaft has impeller, and impeller has hollow rotor chamber, is provided with the static Pitot tube for being provided with suction inlet and be connected to pump discharge vane rotor is intracavitary.Pump Suction Nozzle is set in one end of pump case, Pump Suction Nozzle is connected to through channel with the intracavitary suction inlet of vane rotor, it is characterised in that：The runner of vane rotor chamber is radial in radial directions；Pump Suction Nozzle runner and axis are concentric；Mechanical seal is arranged between the intracavitary suction inlet of vane rotor and Pump Suction Nozzle runner.
Description
Technical field
The present invention relates to a kind of fluid pumps.
Background technique
In industries such as petroleum, chemical industry, chemical fertilizer, metallurgy, mining, carbon black, papermaking, pump is that liquid is essential sets for conveying
It is standby.Mechanical seal be pump important component, pump conveying liquid leakage, majority be because mechanical seal leakage and caused by.
Pump conveying liquid leakage both pollutes environment, it is also possible to cause safety accident.
The maintenance of pump, it is time-consuming and laborious and expensive.
The defect of existing pitot tube pump：1, mechanical seal setting cannot normally make in impeller outer, mechanical seal leakage pump
With.
Open type rotary jet pump does not succeed due to the defect of design.
Summary of the invention
The object of the present invention is to provide a kind of open type pitot tube pumps, and its object is to solve pump to make because of mechanical seal leakage
At fluid leakage problems, provide that a kind of mechanical seal setting is intracavitary in vane rotor, and mechanical seal allows to have certain leakage rate
The pump of (leakage liquid is in rotor chamber) without influencing normal use.
The technical solution adopted by the present invention is that：
Open type pitot tube pump is equipped with pump shaft in pump case with bearing bracket stand, and being fixedly connected on pump shaft has impeller, vane rotor chamber
Runner be in radial directions it is radial, impeller have hollow rotor chamber, be provided in the rotor chamber of impeller static
The Pitot tube for being provided with suction inlet and be connected to pump discharge.Pump Suction Nozzle is set in one end of pump case, Pump Suction Nozzle is through channel and leaf
Take turns the intracavitary suction inlet connection of rotor, it is characterised in that：Pump Suction Nozzle channel and axis are concentric.Mechanical seal is arranged in vane rotor chamber
Between interior suction inlet and Pump Suction Nozzle channel.
The positive effect of the present invention is：Present invention advantage compared with existing pitot tube pump is：1, due to mechanical seal
It is located at that vane rotor is intracavitary, mechanical seal, which has certain leakage rate not, influences the normal use of pump.2, the diameter contracting of mechanical seal
Small, mechanical seal is located proximate to bearing, and mechanical seal service life extends.3, due to position that Pitot tube is connect with pump discharge
Middle position on pump case side wall from axle center to outer rim, so Pitot tube is short, the amplitude of oscillation is small when use, not with impeller phase attrition
Damage.4, impeller diameter can be greater than existing pitot tube pump.5, the failure rate pumped is reduced.6, pump bulk life time extends.
Detailed description of the invention
Fig. 1 is schematic diagram of the invention.
Specific embodiment
The invention will be further described below by way of examples and with reference to the accompanying drawings：
As shown in Figure 1, open type pitot tube pump, is fixedly connected in the pump case 1 formed by the pump housing 11 and pump cover 12 with bearing 2
Be provided with pump shaft 3,3 end of pump shaft is fixedly connected the impeller 4 formed by impeller body 41 and impeller cover 42, suction eye 6 with
Mechanical seal 5 is provided between Pump Suction Nozzle runner 91.The impeller 4 is that unshrouded impeller namely its end have opening, impeller stream
Road 7 has hollow rotor chamber 43 at radial and impeller 4 in radial directions, is equipped on pump cover 12 to impeller 4 and is turned
The Pump Suction Nozzle runner 91 protruded into sub- chamber 43, Pump Suction Nozzle runner 91 and suction eye 7 form a channel.
The middle position from axle center to outer rim on the side wall of pump cover 12 is equipped with pump discharge 10, and pump discharge 10 and setting exist
Pitot tube 8 in rotor chamber connects, and Pitot tube 8 is static and is provided with suction inlet 81.
In use, pumped (conveying) medium passes through mechanical seal 5 from Pump Suction Nozzle 9 again through impeller again by runner 91 as shown by arrows
Suction inlet 6 enters rotor chamber 43 through impeller channel 7, and since 3 impeller 4 of pump shaft rotates, pumped (conveying) medium is in impeller channel 7 and turns
High-speed rotating kinetic energy is obtained in sub- chamber 43, the pressurization of high speed kinetic energy stagnation is changed into pressure energy to by suction inlet by Pitot tube 8
After 81 enter Pitot tube 8, it is discharged by pump discharge 10.
