High Viscosity Rotary Screw Pump, Concrete Screw Pump price, Asphalt Bitumen pump

Overview and purpose:

Three screw pump is suitable for a variety of non-corrosive oil and similar oil and lubrication liquid. Conveying the liquid viscosity range is generally 3.0-760mm2 / s (1.2-100oE), the high viscosity of the medium may be followed by a warming Visbreaking conveyed. Its temperature does not exceed 350 °C.

Three screw for conveying fuel oil, lubricating oil, hydraulic oil, crude oil, asphalt and other similar oil lubricants and lubricating liquid.

Three screw pump lubrication pump in the industrial field, in the hydraulic system for hydraulic pump for conveying and booster pump in the fuel system, transmission and fuel pumps in the oil system.

Product Features:

(1) The medium is a straight line, without agitation and without pulsation;

(2) Low vibration, low noise;

(3) High pressure, high efficiency;

(4) The structure is simple, easy accessibility;

(5) Minor wear, long life.

46 - screw the helix angle of 46 °

Q:How many kilograms of water pump are there in the automatic washing machine on the market?: Suitable for supporting high pressure sprayer, portable car washer. Water pump with overflow circuit. And comes with pressure switch, overflow switch double insurance

Q:Rules for operation of centrifugal pumps: Working principle and process flowWorking principle: when the drive motor with high-speed rotating impeller, full of fluid in the pump body under the action of centrifugal force, was thrown from the impeller center to the outer edge of the impeller, in this process, the fluid energy, improve the pressure can, at the same time also increases the energy flow rate increase. The liquid from entering the pump impeller shell, the liquid flow gradually widened, the liquid velocity decreased gradually, which will be part of the kinetic energy into pressure energy, which further improves the static pressure of liquid, and liquid with high pressure in pressure pipeline. When the liquid from the leaves out when the impeller center creates pressure and low pressure than the out plane is big, under pressure drive, liquid is continuously from the center of the impeller suction, with the pressure of continuous discharge.

Q:You'd better point out the details.... There are 2 best ways of experience and formulaCan you say a simple point, such as multi-stage pump, when the pump is higher than the motor, 30 wire is the next mouth how to do?: For the first time, the pump and motor were placed on the base and not fastened (Cu Zhaozheng);Second times, the pump and motor have been tightened, the inlet and outlet flange bolts are not fastened;Third times, the pump runs 24 hours later.

Q:Centrifugal pump flow, why can be adjusted through the outlet valve? Can the flow of the reciprocating pump be adjusted in the same way?. Why: Reciprocating pump is a positive displacement pump, the volume change of flow is the unit of time, constant flow speed constant, can not rely on increased resistance to change the flow resistance increase is only leaked, only small changes in flow.

Q:Operating procedures for measuring pumps: Pressurization(1) for the discharge pressure below 2.0MPa, then the pump stroke length should gradually increase, each increase of 20%, to maintain 15 minutes.(2) for the discharge pressure greater than 2.0MPa, you need a special pressure, to ensure that the pump discharge pressure gradually increased, each time for the final row pressure of 20%.(3) when the pressure is not increased, the stroke of the pump is gradually increased by 20% strokes per time.Note (1) when pressure is applied, the pressure gauge should be observed at the side of the loading side (slow motion)(2) check ammeter, forbid overload

Q:Brief description of centrifugal pump on / off operation: First, the preparation before the start(1) carefully check the inlet and outlet pipe line, valve, flange and pressure gauge joint of the pump, whether the installation is safe, comply with the requirements, whether the flow is correct, whether the anchor bolt and other connecting parts are loose or not.(2) add lubricating oil to the bearing case, and the oil level is 2/3 of the gauge of the bearing box.

Q:How many millimeters is the diameter of the water outlet of the four inch pump?: If it is a centrifugal pump, the nominal diameter of the outlet is less than 4 inches, there is a conical short tube to enlarge the standard 4 inch outlet flange, from here, is the standard 4 inch flange connection.

Q:What are the starting and stopping procedures for centrifugal pumps?: Operation method and operation procedure of self-priming centrifugal pumpClick number: 440 release time: 2011-7-24Centrifugal pump method, centrifugal pump operation steps, centrifugal pump use steps

Q:Fire control center manually start the fire pump directly, multi line control, called straight up line NHKVV-7*1.5, my understanding is: straight line from fire control center: The vertical line NHKVV-7*1.5 is the remote starting line of fire controller to fire pump room.

Q:How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?: If you're allowed to spend a minute, you can do it 20 times a minute, and that is, the amount of water you sprinkle at a time (1000) is *20.1000 (ML) *20=20000 ml =20 liters, this is the flow,Here is a formula for you to see,Pump displacement * pump speed = flow,
