High-pressure pump for high pressure rotary jet grouting to provide high-pressure dynamic equipment for buildings, highways and other ground reinforcement, can also be used for supporting high-pressure water jet rock breaking coal, underground hydraulic prop for liquid, anchored water conservancy expansion bolt Pumping high-pressure water, large underground dredging cleaning and cleaning.
High-pressure pump role and purpose
1, high pressure piston pump
High-pressure plug piston pump for petroleum, chemical, fertilizer industry as a process pump, metallurgy, rolling mills, high pressure water descaling, construction, shipbuilding, sugar, paper, chemical and other industries of high pressure water cleaning descaling, oil field water injection, boilers Water supply, the power source of hydraulic machinery, as well as food, pharmaceutical and other parts of the need to produce high-pressure liquid, the transmission medium is fluid without solid particles.
High-pressure piston pump, including high-pressure three-piston pump, the pump is all horizontal, it is more stable than the vertical, small vibration, assembly and disassembly, easy maintenance. Also known as three-cylinder pump, with a uniform flow, pressure pulsation is also reduced accordingly.
Model series are: 3P00, 3P10, 3P20, 3P30, 3P40.
2, high-pressure reciprocating pump
(1) high-pressure reciprocating pump for cleaning pumps, process pumps, urea copper pump, ammonia liquid ammonia pump, food homogenization pump, detergent slurry pump, ammonia pump, slurry pump, pentosan pump, Pressure pump, water pump, phosphorus removal pump, oil pump, rust pump
Assembly type: horizontal, fixed, mobile.
Drive type: a motor, diesel engine, gear box, pulley, electromagnetic speed control, frequency control. Each variety of pumps are equipped with safety regulators, pump pressure can be adjusted. Pump material alloy steel, martensite, austenitic stainless steel, 316,316 L duplex steel.
(2) high-pressure reciprocating pump features:
High pressure reciprocating pump pressure should generally be between 10MPa ~ 100MPa. It is a positive displacement pump, with the volume of the working chamber to periodically change the volume to achieve the purpose of conveying liquid; prime mover mechanical energy directly into the pump through the pressure of liquid; pump capacity depends only on the working chamber volume change and its value The number of changes in the unit of time, in theory, has nothing to do with the discharge pressure. Reciprocating pumps are cyclical changes in the volume of the working chamber by means of reciprocating motion of the piston in the working chamber of the cylinder (or by periodic elastic deformation of flexible elements in the working chamber, such as membranes and bellows). Structurally, the working chamber of the reciprocating pump is separated from the outside by a sealing device, and communicates with the pipeline through a pump valve (suction valve and discharge valve).
3, high-pressure electric pressure test pump
High-pressure electric pressure test pump inherits the advantages of the old test pump, with the "three of" a high degree of long life, stable performance, easy operation, flexible movement, light weight, etc. for all types of pressure vessels, pipes, valves and steam Boilers and other hydrostatic test chamber and access to high pressure, liquid, etc., in the initial stage of the test pressure with a larger flow rate, can quickly fill and step-up to shorten the test time. When the pressure exceeds 0.6Mpa, in order to make the pressure test process can be smoother and steadier, the flow will be reduced automatically. There are two kinds of flow in the pump at high and low pressure, and can change automatically. Where the rated discharge pressure can be carried out Any numerical hydrostatic test.
4, high pressure cleaning pump
High pressure pump models are: CM-O, CM-1, CM-2, CM-3.
High pressure cleaning pump accessories are: high pressure water gun, foot valve, three-dimensional rotary nozzle, high pressure resin pipe, high pressure rubber pipe, porous nozzle.
Cleaning pump is an efficient, energy-saving cleaning equipment for chemical plants, thermal power plants, sugar mills, paper mills and other industries heat exchangers or reactors and a variety of pipeline clearance, can also be used for sand casting, all kinds of vehicles , Aircraft, ships, slaughterhouse and other cleaning, through the allocation of accessories and can be used for water blasting, thus overcoming the gas spray noise caused by environmental pollution, affecting personal health and other shortcomings, to do a good job in environmental protection to create the conditions.
The pump is equipped with a variety of nozzles to adapt to a variety of uses, and mounted on a four-wheel flatbed car or dinghy to meet the needs of different occasions, the whole machine mounted on the pallet truck with manpower can Drag, the car in addition to the pump, there are motor, electric control box, roller and high-pressure hose, explosion-proof occasions can be equipped with explosion-proof electrical equipment.
Method of choosing:
1, to determine the medium conditions, high-pressure pump medium is not allowed to appear in the large particulate matter, otherwise it will cause work failure, the requirements of iron pollution should use stainless steel plunger pump, acid or alkaline medium should be selected anti-corrosion plunger pump ;
2, to determine a reasonable flow range, high-pressure pump model nominal flow rate, the selection should be considered appropriate margin range;
3, to determine the appropriate pressure level, with the filter press should be used variable pump, slurry should be used low pressure pump, to reduce waste;
4, to determine the above parameters, according to the principle of rather big, according to the standard model selection of high-pressure pump;
5, with its increasing use, manufacturers need to pay attention to the relevant parameters and information;
