Background
At the present stage, with the sustainable development of economy in China, the centrifugal pump is widely used as a general mechanical product, the demand of the centrifugal pump in the fields of thermal power generation, petrochemical industry and the like is huge, reliable shaft end sealing plays a very important role in safe and stable operation of the pump, and the mechanical sealing commonly used at the present stage has two forms of self-circulation and simple mechanical sealing, wherein the conventional simple mechanical sealing needs a power plant to provide condensed water with the pressure about 0.1MPa higher than that of the water inlet of the centrifugal pump as sealing water, otherwise, the self-circulation mechanical sealing needs to be selected, but the system is complex and the cost is much higher than that of the simple mechanical sealing.
At present, the prior art in the technical field is as follows: the self-circulation container type self-circulation mechanical seal is selected in power plants and chemical plants without pressure condensate systems on the site, but the mechanical seal structure and the pipeline system are complex and have higher price.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to realize saving this consumption reduction, improve product competitiveness, for solving above-mentioned problem, the utility model provides a high-efficient mechanical seal system of saving this consumption reduction.
The purpose of the utility model is realized with the following mode:
the utility model provides a festival this consumption reduction's high-efficient mechanical seal system, includes water seal body and mechanical seal, is equipped with the pressure boost chamber between water seal body and mechanical seal, and one side that the water seal body is close to mechanical seal is equipped with the cavity closure plate, is equipped with the cavity gland in one side that the cavity closure plate is close to mechanical seal, cavity gland and cavity closure plate all connect the water seal body through the bolt, and the inside pressure boost gear that is equipped with of cavity gland, pressure boost gear passes through the key-type connection pump shaft, is equipped with apopore I on cavity gland upper portion, is equipped with apopore II on water seal body upper portion, II upper portion threaded connection outer pipeline of apopore, the L type that the outer pipeline other end and mechanical seal were inside advances water piping connection, and L type inlet tube.
The axes of the water outlet I and the water outlet II are overlapped.
The mechanical seal is a cartridge mechanical seal.
The outer pipeline is a U-shaped pipe.
Compared with the prior art, the utility model discloses can be through pressure boost gear, realize the cavity gland, the pressure boost of the water of the intracavity that the cavity closure plate encloses, pressure water gets into mechanical seal, realize blocking of pump water-logging, also realize the sealed of centrifugal pump, the water through pressure boost gear plays the effect of pressure condensate water, save the expense of purchasing expensive self-looper machine seal for the centrifugal pump is supporting, it does not have pressure condensate water and can use low cost's simple and easy machine seal to satisfy the power plant, can be customer reduce cost, can realize high-efficient sealed demand again, realize saving this consumption reduction, improve product competitiveness.

Fig. 1 is a schematic structural diagram of the present invention.
The hydraulic pump comprises a water seal body 1, an outer pipeline 2, a water outlet I3, a water outlet II 4, an L-shaped water inlet pipe 5, a mechanical seal 6, a pump shaft 7, a boosting gear 8, a cavity blocking plate 9 and a cavity gland 10.
Detailed Description
As shown in the attached drawing 1, a cost-saving and consumption-reducing efficient mechanical seal 6 system comprises a water seal body 1 and a mechanical seal 6, a pressurization cavity is arranged between the water seal body 1 and the mechanical seal 6, a cavity blocking plate 9 is arranged on one side, close to the mechanical seal 6, of the water seal body 1, a cavity pressing cover 10 is arranged on one side, close to the mechanical seal 6, of the cavity blocking plate 9, the cavity pressing cover 10 and the cavity blocking plate 9 are connected with the water seal body 1 through bolts, a pressurization gear 8 is arranged inside the cavity pressing cover 10, the pressurization gear 8 is connected with a pump shaft 7 through a key, a water outlet I3 is arranged on the upper portion of the cavity pressing cover 10, a water outlet II 4 is arranged on the upper portion of the water seal body 1, the upper portion of the water outlet II 4 is in threaded connection with an outer pipeline 2, the other end of the outer pipeline 2 is connected with an L-shaped.
The axis coincidence of apopore I3 and apopore II 4, the water of being convenient for in the cavity gland 10 gets into outer pipeline 2.
The mechanical seal 6 is a container type mechanical seal 6, is simple and convenient to install, has no artificial installation error, is suitable for most stuffing boxes, is easy to replace packing or bearing seal, is convenient to dismantle, is easy to refit outside a field, and is easy to install in places which are difficult to install.
The outer pipeline 2 is a U-shaped pipe, so that the installation is convenient, and the installation space is saved.
The working process of the utility model is as follows: during operation, the booster gear 8 is driven by the pump shaft 7, water in the booster cavity starts to be pressurized, the water in the cavity gland 10 enters the outer pipeline 2 through the water outlet I3 and the water outlet II 4 after being pressurized, and then enters the mechanical seal 6 through the outer pipeline 2, so that the water in the centrifugal pump is blocked, and sealing is further realized.
It is particularly noted that the water seal body 1 is prior art and well known to those skilled in the art, and will not be described in detail in this specification.
Other content participates in the prior art.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
