ME2400 Vortex Flowmeter works on the Karman vortex street principle that swirls generated by a bluff body in the pipe. The number of swirls are proportional to the volumetric flow in the pipe. Vortex flowmeter widely used for gases, steam and liquid applications. It is ideal for measuring saturated and superheated steam in large facilities to improve steam production efficiency.

The flow meter RSJ-50 is installed in the hydraulic compartment of the fuel dispenser. And it is designed to measure the volume of fuel passing through the hydraulic system of the fuel dispenser. In general, for this piston flowmeter, its accuracy is ±0.2%. Compared with similar products, this accuracy is higher and its lifespan is long-lasting. The flowmeter is an important guarantee for the metering function of the tanker. It can still work normally in an ultra-low temperature environment of minus 40 degrees. Material & Structure of Flow Meter RSJ-50 ◈Body material: aluminum alloy housing, stainless steel sleeves, composite piston seal, stainless steel rocker mechanism◈Structure: stainless steel cylinder liner, four-piston strokes◈Advantage: novel appearance, small body, high strength, good wear resistance, accurate measurement, long service life. Working principle The principle of operation of flow meter RSJ-50 is based on the passage of fuel through a metering device. Inside the flowmeter housing, it has four cylinders with pistons operating due to the kinetic energy of the liquid passing through them. The pressure of the liquid is created by an external oil transfer pump – ZYB-50. The pistons are placed in pairs on two connecting rods in four mutually perpendicular measuring cylinders with a volume of 0.125 liters each. Fuel alternately enters each of the four cylinders, then is fed to the output of the volume meter. Pistons with connecting rods under the pressure of fuel perform reciprocating motion in the cylinders. Connecting rods rotate a vertically positioned crankshaft, the free end of which protrudes outside the housing and is connected to the pulse generator by means of a coupling. It can complete with a rectangular O-ring IO50-09. Besides, O-rings are oil & gas-resistant with an operating temperature range from -40°C to +55°C.

WASTE MINERAL OIL AND PETROLEUM PRODUCTS PROCESSING SYSTEMS Waste mineral oil recycling plant distillation refinery manufacturing assembly, The net work of waste oil recycling machines is made from 50 liters to 100,000 liters. The oil produced by the machine can be used as generator fuel without adding any additives. Crude oil processing distillation systems, Fuel oil processing and Bitumen asphalt oxidation systems and Various processing units of petroleum products. Additional information H.K Makine carries out turnkey projects in the country and abroad on waste oil recovery systems (waste oil, mineral oil, bilge oil, machine oil, etc.) of petroleum derivative products. Waste oil recovery facility is a company that tries to keep customer satisfaction at the highest level with its expert staff in installation, piping, electronic installation, automation, design and personnel training. The biggest advantage of H.K Makine in the operation of the waste oil recovery facility is that it does not leave its customers alone in the operation of the system, regardless of whether it is domestic or abroad. Waste Oil Regeneration Process and Machine Operation ●Basically, these types of oils (engine oil, hydraulic oil, gear oil, cutting oil, mixed petroleum oils) are used in waste oil recovery facilities. ● It is the conversion of waste oils into base oils and diesel under high temperature pyrolysis conditions in order to reuse waste oils. ● Waste oils are distilled at high temperatures and hydrocarbon molecules are broken down and a new oil is formed by aligning with a new combination. ● During the distillation process of waste oils, waste oil turns into gas and then turns into oil through the cooling process and is separated according to their density according to the demand and the final product is obtained. ● In the process of improving oxidation, bad odor and color in the refined oil, it removes the residual asphalt, moisture, acid, carbon oxidation in the oil. Obtained Products; ● Diesel ● Thin Base Oil ● Thick Base Oil ● Fuel Oil Waste Oils It is recycled in 2 main ways as Refining and Regeneration and separated according to 3 main categories. refining The process of converting waste oils into base oil or petroleum products in accordance with national or international standards and specifications by refining. Regeneration The process of obtaining original oil in accordance with international standards, specifications and intended use by removing all kinds of pollutants, oxidation products and particles from waste oils.

HK MAKINE carries out turnkey projects in the country and abroad for the establishment of waste oil recycling facility. In Europe, Arab countries and African countries, the installation, assembly, design, electrical installation, piping work, personnel training, automation, insulation, performance tests and commissioning of the waste oil recycling facility at the desired capacity are carried out on a turnkey basis. Waste oils, which are among the hazardous wastes, have been an important part of the management plans of the countries. The Waste Oil Treatment Machine has an important role in minimizing the negative effects of waste oils that harm the environment and human health, and in using these hazardous waste oils with the best possible technologies to benefit the country's economy. Countries need to work in harmony with mineral oil facilities, recovery and disposal organizations, waste oil carriers, laws and regulations, which form the basis of waste oil management. In the management of waste motor oil recovery facilities, in addition to protecting the environment and human health at every stage, sensitivity on safety issues in all services should be kept at the highest level and should be continuously improved. Waste oil and used oil recycling plants are specially designed to convert used oil into quality base oil. Waste oil plants are an economical waste oil re-refining method that is not only an investment but also an environmental benefit. We have incorporated it into the front-end and back-end systems of waste oil recycling plants to perfect the combination of various primary separation and after-treatment steps. It ensures proper dehydration and pretreatment of the used oil so that it can be distilled in high vacuum to prevent cracking in the non-cracking evaporation unit. Working Principle of Waste Oil Recycling Plant Waste oils are converted into base oils and diesel by high-temperature separation method in order to reuse waste oils. By applying high temperature distillation to waste oils, their molecules are broken down and a new oil is formed. During distillation, the waste liquid oil turns into gas, and then it is cooled and separated according to their density in liquid form to obtain the final product. Obtained products; • Diesel • Thin base oil • Thick base oil • Fuel oil Mineral waste oils can be recycled by 2 different methods. These methods are as follows. Refining The process of refining waste mineral oils and converting them into base oil or petroleum products in accordance with national or international standards is called refining. Regeneration The process of obtaining original oil in accordance with international standards and specifications by removing the contaminants and foreign particles found in waste mineral oils is called regeneration. Our company offers turnkey solutions in the establishment of waste oil recycling plant, mineral waste oil recovery plant, waste motor oil recycling machine, mobile waste oil recycling machine, waste oil recovery plant, waste oil treatment machine and factory installation.

We offers high quality hose for oil & gas recovery. Gas station oil and gas recovery refers to the collection of volatilized gasoline oil and gas during the process of loading and unloading gasoline and refueling vehicles, or reducing the pollution of oil and gas by one or two methods of absorption, adsorption or condensation, or change the oil and gas from gaseous to liquid, and then to gasoline again, so as to achieve the purpose of recycling. The oil and gas recovery coaxial hose is used in the oil and gas recovery system of the oil dispenser. During the refueling process, it is connected to the oil and gas recovery fuel nozzle and the oil and gas separation valve. Between the middle layer and the outer wall is an oil circuit, and the middle pipe is a gas circuit. When refueling, the oil and gas are drawn into the underground oil tank from the gas circuit. The metal braid of the tube provides excellent kink resistance, low elongation and long service life.
