随州骏龙专用汽车有限公司Watering cartA pump is a machine that transports or pressurizes liquid。It transfers the mechanical energy or other external energy of the prime mover to the liquid, so that the liquid energy is increased, mainly used to transport liquids including water, oil, acid lye, emulsion, suspension emulsion and liquid metal, etc., can also transport liquids, gas mixtures and liquids containing suspended solids。The technical parameters to measure the performance of the pump are flow, suction, head, shaft power, water power, efficiency, etc.According to different working principles can be divided into positive displacement pump, vane pump and other types。Positive displacement pump is the use of its studio volume changes to transfer energy;Blade pump is the use of rotary blade and water interaction to transfer energy, centrifugal pump, axial flow pump and mixed flow pump and other types。Watering cartPump can achieve performance indicators: 1.The pump itself can pump and exhaust by itself;2.No need to fill water, no peripheral vacuum pump, no bottom valve when starting;3.Self-priming height up to 8 meters;4.The start and stop of suction and exhaust devices can be controlled by manual or automatic devices.5.The operation is relatively simple, and there is no need to install valves on the suction and drainage pipe lines;6.Self-priming time is short, etc。For the first time, the conventional sewage pump and suction and exhaust device are designed as an organic unity.The self-priming time is short，High self-priming height，Other self-priming pumps can not be compared;No bottom valve is needed when starting，No irrigation，No peripheral vacuum pump required，The overall project cost is low，It has strong practicability，Also specially designed inlet gas intake device;For the first time, the suction and exhaust device of the sprinkler pump is designed into a bidirectional air chamber structure.The exhaust effect is improved.Special clutch device and fork pulling mechanism are also developed。These are incomparable to other similar pumps, sprinklers。
随州骏龙专用汽车有限公司Fuelling truckOil pump is a kind of light and compact pump，An oil pump having an enclosure made of an aluminum-containing material and a movable mold arranged in the enclosure are presented，其中，The movable mold is made, at least in part, of a sinterable material containing at least one austenitic iron-based alloy，The molded part, which is made of a sintable material, has a coefficient of thermal expansion of at least 60% of the coefficient of thermal expansion of the shell.The oil pump has three categories, such as in-line type, distribution type, monomer type, no matter what kind, the key to the oil pump is a "pump" word。The amount, pressure and time of the pump oil should be very precise and automatically adjusted according to the load。
随州骏龙专用汽车有限公司Fuel truck oil pump is a fine processing, manufacturing process complex parts, oil pump to have a power source to operate, its lower camshaft is driven by the engine crankshaft gear。The key part of the fuel injection pump is the plunger，If you take the syringe commonly used in hospitals as an analogy，Then a movable plug is called a plunger，The syringe is called the plunger sleeve，Suppose a spring is installed inside the pin against one end of the plunger，The other end of the plunger contacts the camshaft，When the camshaft rotates once，The plunger will move up and down in the plunger sleeve once，This is the basic movement of the injection pump plunger。随州骏龙专用汽车有限公司The main parts of the fuel truck oil pump are: camshaft, roller body, plunger and plunger sleeve, plunger spring, rotating sleeve and tooth ring, oil valve and seat and pressure pipe connection。Plunger sleeve and plunger are a pair of main precision parts in fuel injection pump, they are carefully processed and matched with each other, and their diameter gap is only 0.001-0.003mm, this pair of parts can only be replaced in pairs, not separately。
