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;

Q:Why can the centrifugal pump hold down the pressure?
The centrifugal pump can hold pressure because of the suction pipe in the pump at the entrance of a non-return valve (valve).
Q:Because the water pressure of the booster pump is not enough, it can not work automatically. It can only be operated by hand. It is inconvenient to use.
One possibility is the automatic type household booster pump used for a period of time, automatic failure phenomenon, it is mainly stainless steel and other metal products in pipes, long-term precipitation to shut off the power supply after unloading, unscrew the top screw, remove the plastic sheet to be cleaned, and then, according to the original reset, the normal debugging. Can be re used. But that's not why if your booster pump isn't working properly all the time.
Q:Is the centrifugal pump large or small?
NPSH is also called cavitation, cavitation is too big to be.3, pump the liquid when working in the impeller inlet will produce vapor due to a certain vacuum pressure, vaporization of the air bubbles in the liquid particle movement under the impact of erosion on the impeller, the metal surface, thus undermining the impeller and other metal, then vacuum pressure is called vaporization pressure, NPSH is excess vaporization pressure of surplus the energy position of the unit weight of the liquid in the pump suction port of. The unit with annotation, (NPSH) r with. The absorption process is necessary NPSH H: pump suction fluid allows the vacuum pump installation height is allowed, in meters.
Q:Significance of water pump model ISO50-160
Meaning of water pump model ISO50-160: ISO- stands for international standard code (IS). 50- indicates that the inlet diameter of the pump is 50 mm (the complete model IS50-32-160 32- indicates that the outlet diameter of the pump is 32 mm). 160- represents impeller diameter.
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:Water pump spoon pipe for power plantWhich hero can tell me what is the water pump spoon tube ah? And its role
By adjusting the amount of oil entering into the hydraulic coupler, the torque of the hydraulic coupler can be controlled
Q:What are the main performance parameters of the pump?
The main performance parameters of the pump are:The energy obtained by pumping a unit weight of liquid through a pump. In H, the unit is m.
Q:What are the characteristics of a pipe shield pump?
Two, reverse circulation type of shielding pump, its bearings, lubrication, cooling and motor cooling fluid flow direction and the basic type is the opposite. The main characteristic of reverse circulation pump is that it is not easy to generate cavitation. It is suitable for conveying liquid which is easy to vaporize. Sometimes it is also called "easy to vaporize" type. Three, high temperature medium temperature of up to 450 degrees. The cooling water jacket is usually added outside the shielding motor, and a cooling sleeve is added to the outer circulation pipe to cool the high temperature circulating liquid to reduce the temperature of the motor and the bearing. In the case of less power, some manufacturers do not use cooling liquid, but the outside of the motor is equipped with fins and the special winding to adapt to the working conditions, the use of temperature generally can not exceed 400 degrees.
Q:Metering pumps related matters
Rotate to stroke length 100% position. This allows the kit to rotate to the back of the drain hole and align the bottom of the pump. Adjust the hydraulic end and diaphragm to the proper position during the pump operation.The duration of the pulse may not be long enough for the reaction time. With respect to the standard pulse width 80msec, the flow monitor pulse width expansion can be activated, increasing the pulse width to 300msec. Activate the smart switch, remove the cover fixed circuit board, remove the jumper X-1. This activates the extended function and allows more time before the failure instructions.Metering pump installed from the exhaust pump head, the use of self suction liquid imbibition. Keep the suction line as short as possible.
Q:What are the starting and stopping procedures for centrifugal pumps?
The use of centrifugal pump can be divided into three steps, namely, start, run, stop.Start: you should do the following preparation before starting:(1) check the water pump equipment in good condition.(2) the bearings are filled with oil, the oil level is normal, and the oil quality is qualified(3) all the inlet valves of the centrifugal pump are opened.(4) pump water injection or vacuum pump diversion (except for flow), open the vent valve exhaust.(5) check the leakage of shaft seal. It is advisable to fill the seal with a little drop of water.(6) the motor rotates in the right direction.
