Description
Technical field
This utility model belongs to shield machine technical field, is specifically related to a kind of shield machine HBW sealing system.
Background technology
Shield owner's drive system is referred to as " heart " of shield machine, and it is exactly " diaphragm of heart " that main driving seals, and the effect that the most main driving seals is most important.Shield machine is in the tunneling process of underground, and owing to shield machine is usually located at below ground tens meters, excavation face exists bigger water, soil pressure, with pressure after water, soil, silt easily enter main drive internal.Existing shield owner drives that sealing system sealing effectiveness is bad, cannot effectively judge branch pressure, it is impossible to hold the operating conditions providing good to main drive shaft, main driving is shorter for service life.
Utility model content
The purpose of this utility model is to solve technical problem present in prior art, a kind of simple in construction, practical reliable, simple to operation is provided, the good operating conditions of offer can be held to main drive shaft and be effectively improved shield owner and drive the shield machine HBW sealing system in service life.
In order to achieve the above object, this utility model is by the following technical solutions: a kind of shield machine HBW sealing system, including HBW pump, manual ball valve, choke valve, reversal valve, air-operated solenoid valve, flow distributor, first ball valve, first Pressure gauge, second ball valve, second Pressure gauge, described HBW pump is connected with air-operated solenoid valve and manual ball valve respectively, described manual ball valve is connected with choke valve, described choke valve is connected with reversal valve, described air-operated solenoid valve is connected with flow distributor, described flow distributor is connected with the first ball valve and the second ball valve respectively, described first ball valve and the second ball valve respectively with shield owner's drive connection, described first ball valve is provided with the first Pressure gauge with the pipeline of shield owner's drive connection, described second ball valve is provided with the second Pressure gauge with the pipeline of shield owner's drive connection.
Further, the pipeline that described HBW pump is connected with air-operated solenoid valve is provided with filter.
Further, described flow distributor is gear flow allotter.
This utility model hinge structure has the advantages that shield machine HBW sealing system of the present utility model is mainly made up of HBW pump, manual ball valve, choke valve, reversal valve, air-operated solenoid valve, gear distributor, the first ball valve, the first Pressure gauge, the second ball valve, the second Pressure gauge, simple in construction, practicality are reliably, simple to operation, by injecting and keep the lubricant grease of certain pressure, the operating conditions providing good is held to main drive shaft, it is effectively increased shield owner and drives service life, provide guarantee for shield machine tunneling construction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference implication is as follows: 1, HBW pump；2, filter；3, manual ball valve；4, choke valve；5, reversal valve；6, air-operated solenoid valve；7, flow distributor；8, the first ball valve；9, the first Pressure gauge；10, the second ball valve；11, the second Pressure gauge.
Detailed description of the invention
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
nullAs shown in Figure 1，A kind of shield machine HBW sealing system，Including HBW pump 1、Manual ball valve 3、Choke valve 4、Reversal valve 5、Air-operated solenoid valve 6、Flow distributor 7、First ball valve 8、First Pressure gauge 9、Second ball valve 10、Second Pressure gauge 11，HBW pump 1 is connected with air-operated solenoid valve 6 and manual ball valve 3 respectively，Manual ball valve 3 is connected with choke valve 4，Choke valve 4 is connected with reversal valve 5，The pipeline that HBW pump 1 is connected with air-operated solenoid valve 6 is provided with filter 2，Air-operated solenoid valve 6 is connected with flow distributor 7，Flow distributor 7 is gear flow allotter，Flow distributor 7 is connected with the first ball valve 8 and the second ball valve 10 respectively，First ball valve 8 and the second ball valve 10 respectively with shield owner's drive connection，First ball valve 8 is provided with the first Pressure gauge 9 with the pipeline of shield owner's drive connection，Second ball valve 10 is provided with the second Pressure gauge 11 with the pipeline of shield owner's drive connection.
When cutterhead starts, reversal valve 5 is opened, HBW pump 1 starts, air-operated solenoid valve 6 is opened, lubricant grease keeps certain pressure to enter main driving by the first ball valve 8 and the second ball valve 10, hold the operating conditions providing good for main drive shaft, when the numerical value of the first Pressure gauge 9 and the second Pressure gauge 11 is all higher than setting upper pressure limit, the first ball valve 8 and the second ball valve 10 are closed.When the first ball valve 8 and the second ball valve 10 are all closed, reversal valve 5 cuts out, and cuts off HBW pump 1 source of the gas, and HBW pump 1 cuts out.When in the first Pressure gauge 9 and the second Pressure gauge 11, any one numerical value is less than when setting low pressure limit, and reversal valve 5 is opened, and HBW pump 1 starts, and the first ball valve 8 is connected with the second ball valve 10.When cutterhead stall, reversal valve 5 cuts out, and HBW pump 1 cuts out, and air-operated solenoid valve 6 is closed.
