Brief introduction

Twin screw pump is an important fluid conveying equipment. Because of its large volume flow, and it can transport medium with low viscosity without shearing, it is widely used in various industrial processes, also known as positive displacement twin screw pump, double gear pump and double shaft conveying pump.

Xinglong twin-screw pump is a positive displacement pump. The liquid is transported through a certain geometry cavity formed by sealing between the mating pairs (spiral sleeve and bushing). The spiral sleeves do not contact each other, so it has strong anti cavitation ability and can withstand dry operation within a certain time range. The material of pump overflow parts is determined according to the specific characteristics of the fluid materials transported.

High temperature twin screw pump is usually equipped with a heating sleeve in the pump body or gear box, so that the bearing, mechanical seal and synchronous gear can work under appropriate temperature conditions. The transportation of high temperature asphalt, polymer and adhesive is the most common practical application of high temperature twin screw pump.

If the delivery temperature drops, the viscosity will rise rapidly. If the medium cannot be pumped out in time, the pump body or pipeline is in danger of solidification. With the increase of the viscosity and the increase of the discharge pressure. The high-temperature twin-screw pump must be able to overcome the adverse effect of temperature change on the pump and maintain high pump efficiency and delivery stability.

If the medium is transported at a high shear rate, its physical properties may change. Because the material in the high-temperature twin-screw pump cavity laminar flow movement, has not been agitated and shear, so in the above material transportation application is successful.

The axial growth of driving shaft and driven shaft, the radial growth caused by thermal expansion and the change of fixed position of base plate are also considered to be practical factors that must be considered in the design of high-temperature twin-screw pump. These Xinglong pumps have sufficient experience to deal with the specific transportation conditions of customers.

Advantages

Heat preservation conveying - heating sleeve is set in pump body or gear box

Optimization design - all factors that affect the design process due to temperature changes are involved

Reliability - the wear-resistant screw material allows the pump to withstand accidental contact bites due to solid particles

Non pulsating delivery - media will not be agitated, squeezed or sheared during pumping

Flexibility - has a certain self-priming capacity, and can change the pump speed to meet the needs of more working conditions

Low vibration - even under the conditions of low inlet pressure, low viscosity medium and high-pressure transmission, the pump runs smoothly without vibration

Low noise - working principle virtually eliminates pressure fluctuations

Wide range of applications - can transport high viscosity materials, even at room temperature can not flow materials

Self absorption - with a certain degree of self absorption, usually there is no need to add another forced feeding device or equipment

For you to solve transport requirements include

Full series of standardization, the maximum flow can reach 1200 m3 / h

Output pressure up to 40 bar

Different materials can be used for overflow metal parts, from tool steel to nickel / chromium steel, high acid resistant materials such as duplex stainless steel, Hastelloy and titanium alloy

The standard seal type is mechanical seal, which can be equipped with cartridge mechanical seal and API flushing scheme

In a certain situation, the flow is proportional to the speed, and the flow regulation function can be realized
