&Integrity is gold but better than money, but gold has a price, Integrity is priceless, but it is more important than money. It can bring us unexpected wealth. Only people have abandoned integrity, but integrity will never abandon people again. Please never abandon integrity, because it is your conscience. Sky. Therefore, our company is based on the principle of integrity. Our customers have signed long-term cooperation with many domestic and foreign companies for their food and clothing. Our company specializes in the production of single hydraulic props of various models and specifications. Below I will introduce to you the uses, characteristics, models, specifications, and advantages.
The single hydraulic prop mainly consists of a top cover, a three-purpose valve, a living cylinder return spring, a handle body, a cylinder, a piston, a base, a piston guide ring, a living column guide ring, a spring cylindrical pin, and a limit ring. It is composed of anti-extrusion ring, type sealing ring, type sealing ring, etc.
>It is used in conjunction with metal hinged roof beams for roof support of mining working faces in horizontal or gently sloping coal seams. It can also be used for end support or temporary support of comprehensive mechanized coal mining working faces. It is suitable for ..thickness of coal seam.
&The mining monomer hydraulic uses liquid pressure to generate working resistance and realize the filling and unloading of a single collapsible prop. The single hydraulic prop is an externally supplied constant-resistance single hydraulic prop. It can be used with various roof beams or as a pillar. It can be used to support the blasting working surface and form boards, and can also be used for other temporary support functions. Its main features are long working stroke, low safety management cost, high support strength and retractable pillars, and good safety and stability. The pillar has no load-bearing welds. At the same time, the pillar adopts the principle of suspended pillar. The suspension force generated by the high-pressure liquid acts directly on the end of the Ding cover, reaching four-fifths of the working resistance. The main force is only one-fifth, which greatly improves the support of the pillar. The support has excellent stability and eccentric load capacity, leakage is easy to detect, and safety and reliability are high. Therefore, it can be widely used in thin coal seams, medium-thick coal seams and thick coal seam working faces.
&The working principle of a single hydraulic prop includes the four processes of lifting column, initial support, bearing and return column
When supporting the prop, the following points should be paid attention to
, &The prop should be vertical It is supported on the top and bottom plates, and has a certain "mountain facing" angle, so that the pillar is in a vertical stress state and is not easy to push down.
,&Move the pillar unloading valve toward the side of the coal wall at a certain angle to ensure the safety of pillar withdrawal and prevent the shearer from colliding with the unloading device.
,& There should be an appropriate distance between the pillars and the working surface transportation machinery to prevent the shearer from knocking over the pillars or damaging the oil cylinder, handle valve body and three-way valve.
,&The four claws of the pillar top cover should be stuck on the lace groove of the roof beam. It is not allowed to press the four claws on the roof beam or the roof beam joint.
Characteristics of type plunger suspended single hydraulic prop & It has strong anti-eccentric load ability and greater stability, high reliability, light weight, large working stroke, wide range of use, high strength and stability High, easy to use, low repair and maintenance costs, uses neutral water, low operating costs, etc.&.
Single hydraulic props should select appropriate prop specifications based on the mining height of the working surface, and determine reasonable support sealing based on the pressure on the roof of the working surface to ensure safety and give full play to the technical characteristics of the pillars. Zhou Zihan
(2) New pillars arriving at the mine must pass inspection and retest before they can be used in the mine.
(3) When using the pillar, the pillar should be raised or lowered once or twice to remove the air in the cylinder.
(4) Ensuring that the pillars have sufficient initial support force is one of the keys to making good use of the pillars.
(5) When the lifting amount of the live column is lower than the minimum safe height, it should be replaced with other types of supports in time to avoid being crushed into a "dead column".
(6) When the pillars are returned to the pillars, two methods of close unloading or long-distance unloading can be adopted, which can be selected according to the conditions of the working surface.
(7) It is absolutely prohibited to use hammers, pickaxes and other metal objects to violently hit any part of the pillars to avoid damaging the pillars.
(8) The pillars cannot be placed horizontally for pushing the jack, especially the support handle cannot be used as the fulcrum of the pushing jack.
(9) The retracted pillars should be placed with the top cover facing up and should not be thrown away randomly to prevent coal powder from entering the inner cavity of the pillar.
(10) Because the working surface is dusty, parts are not allowed to be disassembled and assembled on the working surface.
(11) The pillars should be loaded and unloaded with care during transportation, and they are not allowed to be dropped at will to avoid damaging the pillars.
(12) During the experiment and use, it is forbidden to compress the pillar under no load
