英國GRIMM格林進口三螺桿泵概述：
            進口三螺桿泵屬于回轉漸進式容積泵。是一種高精度的機械產品，它結構合理簡單，允許高轉速，壓力脈動小，噪音低，工作平衡可靠，自吸性好，容積效率高。在國內外具有相當廣闊的應用前途。它借助螺桿旋轉，連續不斷地將進口處密封在螺旋空間的液體軸向移動至出口處。因此，具有比齒輪泵，柱塞泵和離心泵更優越的性質。特別適合用于輸送油類和高粘度的液體。
         進口三螺桿泵廣泛應用于輸送石油及各種石油制品，如原油、重油、輕油、潤滑油、燃料油、瀝青、潤滑脂、植物油；以及乳液、糖漿、藥液、高分子等非潤滑性高粘度的液體。因此，在煉油廠、石油化工廠、油船碼頭、瀝青庫、動力液壓設備，艦船和輕工業、食品工業等部門，得到廣泛地應用。

英國GRIMM格林進口三螺桿泵結構特點：

             進口三螺桿泵是由經硬化處理的三根螺桿，裝在一個可更換的襯套內運轉。主桿采用液壓平衡。從桿的軸向力支撐在端蓋上，并由液壓力驅動旋轉。因而螺桿型面僅傳遞液壓扭矩，并不受力，也無磨損，對全部傳動零件而言，均由被輸送介質所潤滑。由特殊型線構成的螺旋型面的主螺桿轉動時，其動密封腔室將把液體由吸入口吸入并沿軸向連續、無脈動地輸送到排出口。三螺桿泵具有多種結構。一般小流量泵，襯套和泵體合為一個。中等流量泵，襯套為一個單獨的零件固定于泵體內，結構為臥式和立式兩種，配備隨機安全閥，有保溫和不帶保溫兩種。大流量泵，襯套為一個單獨零件固定于泵體內。結構為立式，雙吸，配備隨機安全閥。全部采用機械密封，保證了高溫情況下的密封性能。

         進口三螺桿泵具有零件少、易損件少，易損件更換方便等特點，且此類泵運轉平穩、噪音小、工作可靠。

UK GRIMM imported three screw pumps summary:

           imported three screw pumps belong to progressive progressive displacement pumps. The utility model is a high precision mechanical product. The utility model has the advantages of reasonable structure, simple structure, high speed, small pressure fluctuation, low noise, reliable work balance, good self suction and high volumetric efficiency. It has a wide application prospect both at home and abroad. With the aid of a screw, it continuously moves the liquid in the spiral space at the entrance to the outlet. Therefore, the utility model has better advantages than the gear pumps, the plunger pumps and the centrifugal pumps. Especially suitable for transporting oils and liquids of high viscosity.

        The import of three screw pump is widely used in transporting oil and oil products, such as crude oil, heavy oil, light oil, lubricating oil, fuel oil, asphalt, grease, vegetable oil; and liquid emulsion, syrup, liquid medicine, polymer and other non lubricating high viscosity. Therefore, it has been widely used in refineries, petrochemical plants, oil tanker terminals, asphalt reservoirs, power and hydraulic equipment, ships and light industry, food industry and other departments.

UK GRIMM imported three screw pumps structure characteristics:

           imported three screw pump is hardened by the three screw, installed in a replaceable bushing in the operation. The main rod is hydraulically balanced. The axial force of the rod is supported on the end cap and is driven by hydraulic pressure. As a result, the screw profile only delivers hydraulic torque, without force or wear, and is lubricated by the conveying medium for all transmission components. When the main screw of a spiral surface consisting of a special type is turned, the dynamic sealing chamber will absorb the liquid from the suction port and carry it continuously and without pulsation to the exhaust outlet in the axial direction. Three screw pump has a variety of structures. Generally small flow pump, bushing and pump body as one. Medium flow pump, the Bush is a separate part fixed in the pump body, the structure is horizontal and vertical two, equipped with random safety valve, there are two kinds of insulation and non thermal insulation. A large flow pump with a single liner attached to the pump body. The structure is vertical, double suction, equipped with random safety valve. Mechanical seals are adopted to ensure the sealing performance in high temperature.

       imported three screw pump has the characteristics of less parts, less wearing parts, easy replacement of parts, etc., and the pump runs smoothly, with little noise and reliable work.
