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.

Technical parameters:

Q:The function of centrifugal pump: 6. Stuffing box mainly consists of packing, water seal ring, stuffing box, packing gland and water seal pipe. The function of the stuffing box is mainly to close the gap between the pump shell and the pump shaft. The water in the pump is not allowed to flow outside and the outside air is not allowed to enter the pump. Always keep the vacuum in the pump! When the pump shaft and packing friction heat, it is necessary to rely on water seal to control water into the water ring, so that the filler cooling! Keep the pump running properly. Therefore, in the water pump running inspection process, the stuffing box inspection is to pay special attention to! In the operation of about 600 hours, it is necessary to replace the packing.

Q:What is a water pump coupling device?: The water pump coupling device comprises a coupler, a coupling flange, a guide rod and an upper fixing plate, wherein the contact surface of the coupling base and the coupling slide plate is provided with an annular groove, and a soft sealing gasket is tightly fixed on the groove. By adopting the structure, the coupling contact surface of the coupling slide plate and the coupling base is sealed firmly by an annular sealing groove

Q:Why can't the inlet of centrifugal pump be negative pressure?: Therefore, the centrifugal pump inlet pressure can be negative, and negative number, should be used to pump cavitation margin and liquid saturated steam pressure parameters to specific calculation. Sometimes, the liquid saturated steam conveying pressure is very high, such as the 9 m water column, then the minimum pressure of the pump inlet should be equal to 4+9=13 meters, the atmospheric pressure is higher than 3 meters, not only for negative pressure, even higher than the atmospheric pressure to work properly.

Q:Is the vacuum pump air compressor?: No, both work in the opposite way. Air compressor, referred to as an air compressor, is a machine that produces compressed air (positive pressure). The vacuum pump is just the opposite.

Q:Fire pump and shower pump flow head selection, high resolution.: 2, the volume is greater than 10000 is less than 25000, the minimum water consumption of indoor fire hydrant is 15L/s

Q:What does electromechanical vector pump mean?: Commercial buildings: hotels, office buildings, department stores, large saunas, etc.Irrigation: such as parks, playgrounds, orchards, farms, etc.Manufacturing: such as manufacturing, washing equipment, food industry, factories and so on

Q:Why does the centrifugal pump close the pressure to start?: The motor power is selected according to the rated flow of shaft power points plus 15 to 25%, if the outlet valve is fully open to start, the pump flow may deviate from the amount of fixed lot, pump efficiency also reduces a lot, resulting in shaft power greater than the motor power caused by tripping even burned electric machine.

Q:What is the function of the heating pump system for the water pump design?: As the feed water temperature is higher, before starting, if not enough to warm the pump, the pump body temperature is uneven, there is a hot, cool phenomenon. The upper part is inflated and the lower part is inflated"

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:What's the difference between a centrifugal pump and a centrifugal pump? What are they used for?: As the name suggests, centrifuges are machines that achieve centrifugal effects by centrifugal action. And you say the centrifugal pump is only specific, and the same as the pump
