Tanker blade failure

submersible fuel pump failure; if vane pump relief valve is not closed. Due to a foreign body (broken shrapnel, etc.) between the relief valve stuck in the valve and valve seat, causing the fluid inside the loop always do and can not flow in the diesel pump manufacturers, repairs should remove the spool valve to clear foreign body; if Because the pump with the rotor blades and the shrapnel long do high-speed operation, due to fatigue and wear, fracture, resulting in vane pump discharge increases, even when serious loss of pumping action, the pump should be cleared of debris and repair damaged leaves, shrapnel, re-installed after replacing the new; and vane pump and gas separator combined with the surface of the pump pad breakdown or anti-loaded, can also cause vane pump high-pressure chamber communicates with the low pressure chamber, resulting in the loss of the oil discharge vane pump function; if vane pump loose rotor and the rotor shaft, causing the shaft idle, then repair or replace the rotor blades need to pump.

The use of diesel fuel pumps

Diesel pump using compressed air to increase air temperature, air temperature over the diesel combustion test, then injected into diesel, diesel spray and air mixture at the same time their ignition. Compared with the gasoline engine, diesel engine is a diesel dispenser pump has the advantages of low price, good economy, and it has no ignition system, so the fault is less. But the diesel dispenser pump because of work pressure, the structural strength requirements of all relevant parts and has higher rigidity, so diesel heavy, large volume; diesel fuel dispenser pumps fuel injection pump and nozzle manufacture accuracy requirement is high, so the cost is higher; in addition, diesel dispenser pump crude, vibration and noise of diesel engine is not easy evaporation; difficult to start a car, cold winter.

Difference between vane vacuum pump

Vacuum pump is the use of mechanical, physical, chemical or physicochemical methods have been drawn container obtained by vacuum suction device or equipment. Popular terms, the vacume pump is a closed space in a variety of ways to improve, create and maintain a vacuum device.
Press the pump works, pump basically be divided into two types, namely gas pumps and gas transmission pump trap. It is widely used in metallurgical, chemical, food, electronics coating and other industries.
Vane pumps are vane type pump housing (stator ring) in contact with the rotor slot, and the suction side of the liquid from the inlet pressure to the oil discharge side of the pump.

defined tank level gauge system of

tank level gauge system is a static of large reserves of liquid in the tank to measure the generic product. It can be used for inventory measurement, namely the determination of the total amount of product in the tank level gauging can also be used for transmission and transfer of measurement, that is, as product marketing and tax basis. Mainly in two ways: based on the volume-based measure of quality.
In volume-based tank gauging systems, the inventory measurement was performed by measuring the level and temperature. In tank gauging system based on the quality of the stock is measured using a liquid fluid column hydrostatic measurement made. In turn metering or inventory control output, regardless of what method, the reliability and accuracy of measuring instruments is very important.
The main tank gauging equipment manufacturers are Emerson Rosemount, Honeywell grace Stratford, E + H and the like.

What gas stations management software ah

Extraordinary gas station management system (Integrated Management Edition) is a comprehensive type of station management software, including oil management, merchandise management, other management, report management, basic information management, system management module. Its graphical operation, navigational interface is still the continuation of the traditional characteristics of an extraordinary series software provides an intuitive and efficient mode of operation for many users. Software interface design simple, elegant, user-friendly operating procedures, so that ordinary users can quickly grasp without training the software to use operation. Computer configuration requirements low, is a powerful tool for information management service stations. Oil management: including senior members of refueling, ordinary members refueling, forward / back oil management, payment management, oil spill newspaper reported loss, save / store oil / debt membership management, membership points and other functions. Product Management: including procurement of storage, purchase returns, purchase payments, retail and other functions. station management system: including other payments, bank deposits / withdrawals, bank transfers and other functions. Basic information: including oil information, tank information, refueling gun information, vendor information, membership information, vehicle information, employee information, product information and other functions. Opening information: oil beginning stocks, commodities beginning stocks, oil beginning to cope, to deal with commodity beginning, members save money at the beginning, members of the arrears beginning, members of the opening deposit oil function. System Management: includes data backup, data recovery, data initialization, operator management, password changes, unit information, system settings, and other functions.

Pump works are what

manual gas pump: The engine crankshaft via two belt-driven air pump, which drives the piston pump, hit the gas through a pipeline to import gas cylinder. On the other hand accumulator and through a gas pipeline to the gas introduced into the gas cylinder is fixed to the pump's pressure regulator to control the gas cylinder pressure. When the gas pressure within the regulator set-Jane's pressure is not reached, the gas enters the regulator from the gas cylinder pressure regulator valve can not open items; when the gas cylinder pressure regulator adjusted to achieve the predetermined pressure when entering the regulator from the gas cylinder gas pressure regulator valve to open the top, into the pump in communication with the regulator airway and controls the pump inlet through the airway normally open, so that the pump empty load operation , to reduce power consumption, pump protection purposes. When the gas cylinder pressure regulator due to wear and tear and it is set lower than the pressure within the regulator valve return spring to return, disconnect pneumatic air pump control, mechanical pump. My personal solution is crooked between accumulator and catheter valve, cheer when the gas pressure to the inside because the outside world opened up when mentioning the reason because the intake is closed, so accumulator sucked outside air rather then playing into the air sucked out.

The concept of hydraulic piston pump

hydraulic piston pump or solids pumps, hydraulic power pack to drive the hydraulic cylinders, hydraulic cylinders advance the delivery cylinder, the delivery of materials to pipe the output of the cylinder. Generally divided into single and double piston plunger, typical representatives of the four kinds of German Putzmeister solids pumps, which are: EKO single piston, KOS, KOV, HSP three kinds of double-piston pump. The pump belongs to positive displacement pumps, especially for high solid content, long distance pipeline viscous material, the advantage is to run very stable and reliable, but noisy, delivery pressures up 130Bar, displacement of up to 0.5 to 500 cubic meters / hour. Widely used in sewage treatment, solid waste treatment, mining and metallurgy, dredging, dredging, petrochemical, power plants, cement industry and other fields.
