Gas transfer pump and adjustment of the pump body

Measurement and adjustment of the pump include alignment, looking for elevation and leveling three areas.
(1) vertical alignment is to find the gear meshing being, the horizontal centerline. Longitudinal diesel fuel dispenser centerline of the gear meshing is based on the shaft centerline prevail; transverse centerline to gas transfer pump centerline of the outlet pipe shall prevail. Looking positive, according to the mounted device centerline (or base and wall studs centerline) to be measured and adjusted so that the longitudinal internal gear meshing, and cross the center line to gas transfer pump meet the requirements of mobile fuel dispenser drawings and is well connected with other devices. Internal gear meshing , the horizontal centerline dimensions by drawing tolerances within ± 5mm range. Is the shaft centerline elevation (2) to find the elevation of the pump prevail. Generally used to measure the water level when mechanical fuel dispenser looking for elevation. When gas transfer pump measuring, the benchmark reference point on the plant settings, measured water level of the mounted height, and then moved to the journal benchmark, measure the distance from the shaft surface mounted to, and then the pump can be calculated according to the formula shaft centerline elevation.

The advantage of a hydraulic piston pump

Hydraulic piston pumps or solids pumps, hydraulic power pack driven by hydraulic cylinders, hydraulic cylinders advance delivery cylinder, the cylinder will transport material output to the pipeline. Generally divided into single-and dual-piston plunger hydraulic piston pump are positive displacement pumps, especially for high solid content, viscous material long-distance pipelines, the advantage is running very stable and reliable, but the larger noise. Widely used in sewage treatment, solid waste management, mining and metallurgy, dredging, dredging, petrochemical, power plants, cement industry and other fuel transfer hand pump fields. Piston has several decades of history, its popularity depends on two main reasons: one, they do not require external energy - the water's force to provide them with the necessary energy. 2, an apparatus which is extremely simple, only two moving parts. The basic principle is simple piston petrol dispenser pump. Momentum This pump uses a relatively large movement of water to the relatively small volume of water pumped upward. To use the plunger, there must be located above the water pump. For example, on the mountainside have a pond, so that you can install the pump in the pond below. The water from the pond with water pipes toward the pump. Pumps have a valve, this valve and allow water to flow through the pipes to accelerate.

Common Faults and exclusion method stainless steel external gear pump

Air is sucked into the common faults of stainless steel gear pump, following the first volume of the air sucked into this fault exclusion method: Pump with stainless steel end caps on both sides of the gas transfer pump in direct contact with a hard seal, if the flatness of the contact surfaces do not meet requirements, the work of the hydraulic piston pump when air is sucked into the easily; Similarly, the pump and the pressure cap also for direct contact between the cover, the air is easily invade into; If the gland is plastic products, due to its damage or deformation due to temperature changes, but also make Mifengbuyan enter the air. Exclude this failure is: when the flatness of the pump or manual fuel transfer pump cover less than the specified time, you can press shaped route from grinding on the plate with emery also be on the surface grinder grinding to flatness of not more than 5μm, and the need to ensure that the vertical plane of the hole which requires; leakage and the gland to the pump at the head, can be coated with an adhesive such as epoxy resin for sealing.

Hydraulic piston pump with what preparation work

First of all should do the preparatory work before the pump, such as the pre pump etc.. Based on the parameters of outlet flow, petrol dispenser pump current, pressure, liquid level and switched to each other, the principle is to start standby pump, after each part is normal, the pressure up, slowly open the outlet valve, and slowly close outlet valve switch hydraulic piston pump, pump outlet valve switch until it is completely closed, stop by the switching of the pump, but should try to reduce the flow rate fluctuation causing by switching. Why not start centrifugal pump wheel does not train: centrifugal gas transfer pump wheel does not train, that the pump has fault, the fault may be the impeller is what stuck or pump shaft bending over.

Gas transfer pump on an effective way of conventional thermal emission reduction

In wind power, photovoltaic and other new energy due to the defects of its nature, the power source, is not the gas transfer pump can bear the load on the evening, PV will stop power supply, the power market is concerned, the evening air transmission gas station management software is usually the peak electricity usage of social, so still need to rely on the traditional power. According to the development of new mechanical design of pneumatic conveying manual fuel pump, pump has the advantages of small volume, low pressure and in the transportation process due to the gas transfer pump in the pipeline, no dust pollution, better protect your environment. Thermal power plant in the use of hydraulic piston pump is the principle unit equipment for continuous operation, supporting the operation of ash fuel card fuel monitoring system and unit. Green new solutions in addition to enhance the efficiency of coal, there is new energy to harness, mechanical strengthen coal combustion efficiency and environmental protection of the link, in addition to currently known all form of renewable energy generation, solar thermal power generation is green only a stable and adjustable output power and no pollution energy.
