Description
Technical field
The present invention relates to a kind of water pump system, especially relate to a kind of multistage high-pressure water pump system that is used for paper machine.
Background technique
Present stage, the workshop was furnished with two paper machines, and left and right sides mobile phone respectively has a cover high pressure water system (cylinder mould high pressure water, felt high pressure water), like Fig. 1; Totally four motors; Aggregate power 28KW (cylinder mould high-pressure water pump power 11KW, felt high-pressure water pump 3KW), 35 kilograms of cylinder mould high pressure water design pressures.Owing to be mixed with small amount of impurities in the high pressure water, the impurity deposition takes place in high-pressure water pump disc easily in process of production, causes high pressure water pressure to descend, and makes that adhering to foreign matter on the cylinder mould can not get timely cleaning, needs frequent shutdown to unpick and wash.The main defective that exists is to cause the quality of product fluctuation, causes the waste paper of a large amount of paper defects to melt down; Frequent shutdown cleans and causes production capacity to lose greatly simultaneously, directly reduces manufacturing efficiency.The damaged disc of high-pressure water pump disc needs in time to change in addition, and high-pressure water pump is the import pump housing, and every cover expense is about 40,000 yuan, and deposit spare part expense is high, and cost is bigger.Directly increase manufacturing cost.
Summary of the invention
The object of the invention be exactly provide in order to overcome the defective that above-mentioned existing technology exists that a kind of cost is low, life cycle is long, maintenance cost is low, the multistage high-pressure water pump system that is used for paper machine of stable performance.
The object of the invention can be realized through following technological scheme:
A kind of multistage high-pressure water pump system that is used for paper machine; It is characterized in that; Comprise multistage water pump, total valve, one-way valve, first branching valve, second branching valve, the 3rd branching valve, the 4th branching valve, right hand machine cylinder mould pressure duct, right hand machine felt pressure duct, right hand machine cylinder mould pressure duct, right hand machine felt pressure duct, described multistage water pump, total valve, one-way valve connect successively;
Described one-way valve is connected with right hand machine cylinder mould pressure duct through first branching valve;
Described one-way valve is connected with right hand machine felt pressure duct through second branching valve;
Described one-way valve is connected with right hand machine cylinder mould pressure duct through the 3rd branching valve;
Described one-way valve is connected with right hand machine felt pressure duct through the 4th branching valve.
Described multistage water pump employing design pressure is 55 kilograms a homemade multistage pump.
Described multistage water pump comprises motor, power inverter, pipeline, described motor respectively with power inverter, pipeline.
Compared with prior art, the present invention has the following advantages:
1, cost is low, and homemade multistage pump needs expense about about 20,000, and expense is far below the import pump housing;
2, life cycle is long, and homemade multistage pump is not subject to the water quality requirement influence, need not frequently to unpick and wash and change disc;
3, maintenance cost is low, and homemade multistage pump can carry out maintaining through domestic vendors, and excellence far away and former high-pressure water pump just can be changed disc, and disc can't be repaired secondary use problem;
4, pressure stability can be regulated as required, and homemade multistage pump is not easy to stop up with respect to the import high-pressure water pump; Can not produce and stop up the build-up of pressure problem that descends again and again, when there is foreign matter on the cylinder mould surface, can pass through frequency variator; Improve the pressure of water, clear up, can effectively reduce the shutdown number of times.
