Abstract
The invention relates to assembly of hydraulic cylinder sealing members such as a mining hydraulic bracket upright post, a jack and the like, in particular to paste for assembling a hydraulic cylinder sealing member, and solves the problem that lubricating grease used for assembling the conventional hydraulic cylinder sealing member is easy to be adhered to a filter screen of a filter to block the filter because the grease is not dissolved in emulsion. The formula is that: the paste is prepared from 1,000g of polyvinyl pyrrolidone, 10g of sodium alginate, 3 to 3.5g of triethanolamine, 1 to 5g of butylated hydroxytoluene (BHT) serving as an antioxidant and 750 to 850ml of water, and prepared by the following steps of: (1) uniformly mixing the polyvinyl pyrrolidone and the water for later use; (2) uniformly mixing the sodium alginate and the water for later use; (3) uniformly mixing the two kinds of solution, adding the triethanolamine and uniformly stirring; and (4) adding the oxidant BHT and uniformly stirring. The paste has a high process property and high practicability, improves the assembly efficiency of a hydraulic bracket and provides a new solution for solving the problem of blockage of the filter screen of a hydraulic system filter of the hydraulic bracket and improving the cleanness of emulsified oil of a hydraulic system.
Description
Technical field
The present invention relates to the sealing member assembling of hydro-cylinders such as mine hydraulic support column, screw block, specifically is that cream is used in a kind of hydraulic cylinder sealing element assembling.
Background technology
Hydraulic support is one of modern state-of-the-art colliery comprehensive mechanical coal mining equipment, and the particularly development of electro-hydraulic control hydraulic support makes that the efficient of mechanical coal mining is further promoted.Mine hydraulic bracket is combined as coal and is adopted one of support equipment, and its supporting performance is to go up and down to realize through column, screw block, and the degree of cleaning of its system's emulsion are directly connected to the action of column, screw block and the safety of system.
In the assembling process of large hydraulic bracket upright post and screw block; The urethane sealing-ring needs the opening assembling also tightly to be attached in the sealing groove on column and the screw block because its diameter is excessive; Because itself tension force cause can not tightly be attached on the column, this is with regard to for the assembling of hydraulic support has caused very big difficulty, therefore; Manufacturer adopts railway grease such as quicklime grease or lithium soap grease, utilizes its full-bodied characteristic that the urethane sealing-ring tightly is attached on the column.But because railway grease is insoluble to emulsion; In column, screw block course of action, broken up by emulsion easily and be fine granularity and flowing along with emulsion; Be attached on the strainer screen, the phenomenon that strainer blocks often takes place, to such an extent as to hydraulic support can't works better.Need the cost great amount of manpower and material resources to repair or replace, had a strong impact on normal coal work progress.
Summary of the invention
The present invention assembles used railway grease because of being insoluble to emulsion in order to solve present hydraulic cylinder sealing element, and is prone to be attached on the strainer screen, blocks the problem of strainer, provides a kind of hydraulic cylinder sealing element assembling to use cream.
The present invention adopts following technical scheme to realize: cream is used in the hydraulic cylinder sealing element assembling, fills a prescription as follows: PVP K120 1000g, sodium-alginate 10g, trolamine 3～3.5g, antioxidant BHT 1～5g, water 750～850ml;
Process for preparation is following:
(1), 1000g PVP K120 and 450～500ml water are mixed, stir, treat that solution is fully transparent thick subsequent use;
(2), the 10g sodium-alginate is mixed, stirs with 300～350ml water, treating that sodium-alginate and water are fully miscible is evenly faint yellow thick subsequent use;
(3), above-mentioned two kinds of thick solution that prepare mixed stir, add the trolamine of 3～3.5g then, stir;
(4), add antioxidant BHT 1～5g, stirring gets final product.
The hydraulic support emulsion is the formulated uniform liquid solution of hydraulic pressure oil in water emulsion and water, and its staple is a water.And in the prescription according to the invention; Sodium-alginate and PVP K120 are water-soluble polymers; Can be made into the high material of viscosity with water, have the hydrophilic and oleophilic group in its molecule, can well mix with the hydraulic support emulsion; Add the inhibiter trolamine and can be mixed with antioxidant BHT and has high adhesion and can be dissolved in the hydraulic support emulsion, assemble special-purpose cream with emulsion formation uniform liquid and the sealing members such as hydraulic support column, screw block that do not reduce sealing effectiveness.
Compared with prior art, the present invention has enough viscosityes and adhesivity to satisfy the assembling of hydraulicefficiency system sealing member, and can well mix with emulsion; And do not change the emulsion homogeneity; Improve efficiency of assembling, hydraulicefficiency system is stopped up and pollution in order to solve, and new solution route is provided; Obvious social benefit, technical application is worth higher.
Good manufacturability of the present invention, practical, improve the hydraulic support efficiency of assembling, stop up for solving hydraulic support hydraulicefficiency system strainer screen, improve hydraulicefficiency system oil in water emulsion degree of cleaning, new solution route is provided.
