Description
Technical field
The present invention relates to technical field of aluminum electrolysis, concretely relate to one kind and can extend crown block hydraulic system to use the longevity
Life, overhead traveling crane failure rate is low, the Multifunctional crown block hydraulic system that operates steadily.
Background technology
Most of working performance of aluminum electrolysis industry potroom multifunction crane is the hydraulic pressure system designed by overhead traveling crane itself
The power source that system provides, to complete the demand of work in every.Potroom high temperature, high dust, high-intensity magnetic field particular surroundings also just
It is the trump card of hydraulic system service life length, the superiority and inferiority of a set of design of Hydraulic System, it will directly influence electrolysis car
Between multifunction crane work efficiency, by NKM multifunction cranes, the more work(in Zhuzhou that more than 10 years is used for our companies
Can the service condition of overhead traveling crane find, all there is anode lifting physics, Hydraulic System Oil temperature rise is too fast, the system failure frequently etc.
Phenomenon, is learnt by being contacted with producer, and this situation belongs to the performance of hydraulic system aging, and there is also this for other aluminium industry companies
Kind situation.If need to eliminate this situation can only replace all valve groups of hydraulic system, it will meet various duty requirements.For
The service life of hydraulic system can be improved, hydraulic system items duty requirements are not interfered with after using valve group aging to set out
Point, is the pressure value different qualities that each mechanism exports according to aluminum electrolysis industry Multifunctional crown block hydraulic system, we design one
Set can extend the design of Hydraulic System of hydraulic system service life.The design error failure rate is low, operates steadily, and biggest advantage is
Hydraulic pump, the service life of hydraulic valve bank can be extended.
Since 2012, it is powerless that four NKM multifunction cranes using at present show anode lifting, system noise
Greatly, system heat balance high oil temperature failure, indivedual Zhuzhou multifunction cranes also show similar failure, directly influence electrolysis car
Between daily production work.By being found to two kinds of vehicle design of Hydraulic System researchs, design there is it is certain the drawbacks of, exist
Following drawback：
(1) hydraulic system plunger pump inlet port does not design oily filter core, the oily cleannes into hydraulic pump is protected
Barrier, is to cause hydraulic pressure pump volumetric efficiency to decline, noise becomes larger, the immediate cause of lifetime.
(2) NKM crown block hydraulic systems main pump oil suction mode belongs to self-priming fuel feeding design, and (self-priming fuel feeding design is easy
Generation, which is emptied, causes big gun ring phenomenon, and the service life of hydraulic pump reduces 2-3, high to the vacuum level requirements of pump, and hydraulic system is set
Timing does not use generally self-priming fuel feeding to design).
(3) the pressure value summary sheet (one) and design of Hydraulic System schematic diagram provided by hydraulic system for the work of each mechanism
(1) find to design the anode mechanism control valve group of mesohigh and the control valve group of other 7 low pressure mechanisms same during design
It is the true cause for causing after valve group aging system can not establish mesohigh on a oil circuit block, and ours is multi-functional
Crown block hydraulic system anode lifting is powerless, noise becomes larger, the immediate cause that failure rate becomes higher.When hydraulic system starts, hydraulic pump
The big gun ring noise of generation be self-suction hydraulic system design itself there are the defects of.
A set of designing scheme that can extend hydraulic system service life is provided therefore, it is necessary to design.
The content of the invention
The technical problem to be solved in the present invention is in view of the deficienciess of the prior art, providing a kind of prolong the service life
Multifunctional crown block hydraulic system.
A kind of Multifunctional crown block hydraulic system to prolong the service life of the present invention is achieved by following technical proposals：One
The Multifunctional crown block hydraulic system that kind prolongs the service life, including main pump, auxiliary pump, oil level indicator, thermometer, fuel tank, anode oil cylinder
Control valve group, switching valve, crust breaking ram control valve group, grab bucket ram control valve group, crust breaking inclination control valve group, hydraulically-controlled one-way valve
Cylinder control valve group, fixture ram control valve group, spanner lifting cylinder control valve group, spanner rotation motor control valve group, the master
The the first oil circuit block controlled by sequence valve is set between pump and auxiliary pump, anode ram control valve group sets the second oil circuit block,
Mesolow control valve group sets the 3rd oil circuit block.
A kind of Multifunctional crown block hydraulic system to prolong the service life of the present invention has as follows compared with prior art
Beneficial effect：
Present invention point 1：Aid in pumping function bigger.Auxiliary pump can provide≤10Bar pressure oil oil supply functions for main pump,
Hydraulic system heat dissipation circulatory function can be realized again.The advantages of this design：
1. solve self-suction hydraulic pump design itself there are the drawbacks of；
2. entering the oil strainer of 10 μm of design on the oil circuit of main pump, ensure the oil cleanliness into main pump, extend liquid
The service life of press pump.
Inventive point 2：Break traditional design, the oil path block body of system installation valve group is redesigned.System high pressure is worked
Valve group isolation installation.
The high pressure valve group for controlling anode mechanism work is separately installed in an oil circuit block, it is made by order valve action
Realize and connected with disconnecting with system oil-way block, when anode mechanism works, sequence valve works, cut-out and system oil-way block
Connection, fluid all supply oil circuit block B, and this design, has got rid of the leakage of 7 valve groups when working equivalent to anode mechanism
Point, solve because valve group aging produce leakage caused by system establishes not rise high pressure, when anode mechanism does not work, sequentially
Under the action of valve, fluid reaches oil circuit block C, completes all system mesolow work.
Present hydraulic system designs biggest advantage：
Optimize the oil suction mode of hydraulic system, increase absorbing and filtering device, extend hydraulic valve bank, the use longevity of hydraulic pump
Life, and operating pressure in hydraulic work system mechanism is subjected to high and low classification and is recombinated, high pressure is supplied independent work respectively with low pressure
Make, the present invention solves the failure rate for because of the defects of system can not establish high pressure after valve group aging, reducing system, ensures equipment
Safe and stable operation.
It is poor that a kind of Multifunctional crown block hydraulic system to prolong the service life of the present invention can be used for equipment availability environment
Workplace, have one to two group high pressure valve groups in system, most of remaining works the hydraulic system of valve group for mesolow, can push away
Extensively in most of mechanical equipments for quoting hydraulic system.
