Gear pump heating method

In general, the heavier the pump gear pump casing, the higher temperature resistance, compressive strength. Pump material commonly used ductile iron, cast aluminum alloy can also be cast using hard cast, or extruded aluminum alloy profiles manufacturing. When the medium is corrosive, high-cost stainless steel can be used. Foreign high viscosity gear pump to use more nickel, chromium alloy steel as the pump casing material, this material in the strength, reliability and cost of the overall performance is better. In order to solve the trapped oil phenomenon of the gear pump, a symmetrical unloading groove is usually provided on the pump cover, or an asymmetric unloading groove is opened to the low pressure side, a taper unloading groove is adopted on the suction side, and a rectangular unloading Depth of the groove, unloading groove than the hydraulic pump used in industrial gear deeper.

Due to the high viscosity of the medium fed by the gear pump, the media must be heated or insulated in order to reduce flow resistance and increase the suction capacity of the pump. Heating elements are usually used to make viscous liquid heat evenly. If the temperature fluctuations, the delivery of high-viscosity liquid prone to degradation, it is recommended to use fluid heating, especially large displacement gear pump. Fluid heating is divided into built-in, external structure. The so-called built-in gear pump pump body or cover the internal design of the sudden heat jacket, the external is through the screw clamp jacket and pump body together. Into the jacket into the steam, HTF, or cooling water, according to the specific circumstances of the media. Built-in for the delivery of liquid temperature uniformity is higher, or require uniform cooling of high temperature liquid occasions. When the lack of electrical heating or security requirements of the temperature control is not high, the external structure can be used. American VIKING company's internal gear pump, pump head part of the jacket can be transported fluid temperature control, either in high temperature or low temperature environment, can be equipped with an external jacket.

Product Introduction

Jigging Machine is a separation machine with deep tank, which is developed according to the law of layer theory of jigger bed stratification, and on the basis of traditional jigger. The performance of jigging machine has reached the domestic advanced level, and is one of the ideal devices in energy-saving gravity separation. When processing the open-pit mines, the jigging machine is a key machine with the principle of gravity separation. jigging machine pulse curve is like saw-tooth waveform to make rising water faster than the dropping water; enhanced the loose of bed, eased the inhaled role, so that heavy particles in the mineral can fully settlement, greatly improving the sorting capacity and recovery rate of equipment.

Working Principle

Jig machines need water to work, and it loosens materials in vertical alternative water-flows, and it forms different layers of materials of different densities and discharges both layers from up and down discharging ports separately. The basic composition of jigger is jigging chambers, also called jigging boxes, and there are screens in each chamber.

Water and raw ore will be fed from one end of the jigger screen, the ore granules will move in the vertical alternative water-flows. Layers will be formed because of density difference of materials. The minerals with small density will be in the up layer and will flow together with the up pulp flow while material with bigger density will be in the down layer and will discharged from the down discharging port as jigging concentrate.

Application

This jig machine Can achieve a good result in processing such as placer gold, diamond, tungsten, iron, tin, hematite, cope, tantalum-niobium, titanium, manganese, barite, zirconium, chrome and gemstone etc.

Main Feature

1.High capacity, High concentration ratio and recovery
2.Fabricated with highest quality material
3.Easy to install, operate and maintain
4.Water conservation ,Saving water 30-40% than ordinary jig
