Spare parts for heavy and construction Volvo equipments

Volvo Hydraulic cylinder - volumetric hydraulic motor of reciprocating motion. The principle of operation of hydraulic cylinders is largely similar to the principle of the action of pneumatic cylinders. The moving part of the Volvo hydraulic cylinder, which may be a rod, a plunger or the cylinder body itself, performs reciprocating motion. The main parameters that characterize all Volvo hydraulic cylinders are the internal diameter, stroke length, rod diameter and nominal working fluid pressure. Volvo Hydraulic cylinders come in several types: piston, telescopic, plunger, two-sided and one-way. According to the type of attachment, Volvo hydraulic cylinders are divided into models with hinged fastening and rigid fastening. Volvo single-acting hydraulic cylinder makes effort on the movable rod, which is directed only to one side (the working stroke of the cylinder). In the opposite direction, the movable link simply moves back under the action of gravity or a return mechanism, f →

The Volvo hydraulic system works as follows: The diesel engine rotates the shaft of the Volvo hydraulic pump, which converts mechanical energy into energy hydraulic. The hydraulic fluid is piped into the Volvo hydraulic pump and the Volvo hydraulic cylinders through the Volvo control valve system and converted there into mechanical energy of rotation or reciprocating motion. After performing the work, the hydraulic fluid returns to the hydraulic oil tank and enters the Volvo hydraulic pump. The cycle of work is repeated. Exist two types of heavy equipment Hydraulic systems: A volumetric hydraulic system for its operation uses hydraulic motors and hydraulic pumps operating under high pressure up to 350 MPa. This system uses the principle of alternately filling the working chambers of the pump and the hydraulic motor with a hydraulic fluid and displacing it from there under high pressure. The speed of movement of the working fluid in such a system is small. The main factor →

When hydraulic systems are in operation, it becomes necessary to change the flow direction of the working fluid in its individual sections in order to change the direction of movement of the machine's actuators; it is required to provide the necessary sequence of activation of these mechanisms, to discharge the Volvo pump and the hydraulic system from pressure, and so on. These and some other functions are performed by a special hydraulic device - the hydraulic Volvo control valve. In the manufacture of Volvo hydraulic control valves, steel castings, modified cast iron, high and low carbon steel grades, and bronze are used as structural materials. To protect individual elements of the Cat control valves from abrasive wear, sliding surfaces are cemented, nitrided and so on. The dimensions and mass of the Volvo control valve depend on the flow rate of the liquid through which the dimensions of the unit increase. Thanks to the hydraulic system, the Volvo machine receives t →

The Volvo track chain is an important part of the Volvo track, it consists of movable elements that are connected together by means of fingers and bushings. It is this part that comes into contact with the ground surface during operation and exerts pressure on it. Using a crawler chain allows you to reduce pressure on the soil, which increases the throughput of Volvo Heavy Equipment. The Volvo tracks consist of bushes into which the fingers are placed, so joints are formed, allowing the chains to fit tightly the guide and the driving wheel. Like any other equipment, the Volvo equipment, over time, requires replacement of worn out Volvo parts. If you need to replace spare parts like Volvo track chains, you should pay attention to such moments: the length of the crawler chain and the diameter. The Volvo track chain can be mounted on motor grader, tractor, bulldozer and excavator Volvo. Such products are characterized by a long operating term, as well as a high level of patency.  →

Rotation of the working equipment of equipment to the place of unloading the bucket and a reverse rotation to the place of dripping are carried out by turning the turntable or the whole platform (for full-cycle Volvo excavators). The rotation takes approximately 60-70% of the working cycle time and significantly affects its overall duration. The hydrostatic Volvo Swing Motor just performs the function of turning in the horizontal plane of the working equipment relative to the running gear of the Volvo equipment. The Swing Volvo Motor consists of a sturdy steel casing, in which several pairs of Novikov gearing gears are compactly arranged, allowing the transfer of loads significantly exceeding the permissible values ​​for involuntary engagement.

As the name suggests, a Volvo starter for heavy equipment is used to start an internal combustion engine. To do this, it provides a primary rotation of the crankshaft with the required frequency. The starter is an integral part of the electrical system of any modern Volvo equipment. Structurally it is a four-pole DC motor, powered by a Volvo battery. The Volvo engine generates the energy necessary for the movement of the Volvo equipment, due to the speed of the Volvo crankshaft. All electrical equipment works from the same energy. In a stationary state, the engine is not capable of delivering either torque or electric energy. In this regard, it is necessary to "untwist" it with a special electric motor - a Volvo starter motor, and an external power source - a Volvo battery. On motors with diesel power system, as well as on high-power engines, a Volvo starter motor with a gearbox is installed. The planetary gearbox, consisting of several gears, is mounted in the starter  →

Electrical equipment of any Volvo equipment includes an alternator Volvo or AC Volvo generator - a device that converts the mechanical energy received from a Volvo engine into an electrical one. Together with a voltage regulator, it is called an alternator set. Volvo alternators are installed on modern Volvo equipment. They meet the requirements to the greatest degree. Requirements for the Volvo alternator: - the output parameters of the Volvo alternator must be such that in any mode of motion of the machinery there is no progressive discharge of the Volvo battery; - The voltage in the onboard network of equipment powered by the Volvo alternator must be stable over a wide range of speed and load variations. The latter requirement is caused by the fact that the Volvo rechargeable battery is very sensitive to the degree of voltage stability. Too low voltage causes a low battery and, as a consequence, difficulties with starting the engine, too high voltage leads to a battery r →

To convert various types of energy into electrical, special devices are used. One of the simplest mechanisms is the DC Volvo generator. The DC Volvo generator is a device that converts mechanical energy into electrical energy for further use in an external circuit. The source of mechanical energy in this case can serve as any mechanical effort: the rotation of a special handle, the Volvo engine and so on. There are such types of DC Volvo generators: self-excitation inclusion and working on the principle of independent inclusion. The methods of excitation depend on the type of power supply of the device. The self-excited Volvo generator works from external sources, it can be a rechargeable battery. Unlike Volvo alternators (or AC Volvo generators), devices with a constant type of electricity need an uninterruptible power supply that constantly directs the DC current to the armature winding. Because of this, the field of application of such devices is quite narrowly specialized, →

Electric Volvo battery - a chemical source of current, a source of electro-driving force of reusable action. The main specificity is the reversibility of internal chemical processes. That provides its multiple cyclic use (through charge-discharge) for the accumulation of energy and autonomous power supply of various electrical devices and equipment, as well as to provide backup sources of energy in vehicles and Volvo heavy equipment. The most common now are: 1. Lead Acid is the most common type of battery used in Volvo's heavy equipment, or as an uninterruptible power supply in emergencies. 2. Nickel-cadmium (NiCd) - the most widely used as a replacement for a standard galvanic cell, also used in Volvo electric forklifts and other Volvo electrical equipment. 3.

The plunger and piston Volvo water pump are widely distributed, as their work is effective at high final pressure. The purpose of the Volvo water pump in the cooling system is to pump the cooling liquid through the cooling system. The main task is to force the coolant into the cooling Volvo radiator, as a result of the operation of the Volvo thermostat and the start of a large circle of engine cooling. How does the Volvo piston water pump work? The principle of operation of the Volvo piston water pump is to pump the liquid by suction. What does it mean? The piston creates a translational motion, through which the liquid enters the cavity of the lower part of the device from a special tube. When the piston does reverse movement, the valve on the pipeline closes and thereby prevents the fluid from flowing back. However, another valve opens on the discharge pipe. At the primary suction it was closed. These processes are repeated again and again, so that the fluid is constantly pu →

The cooling system plays a very important role, since it prevents the engine from overheating. The most important element of the cooling system is the Volvo radiator, which provides effective cooling of the liquid. The cooling system performs the following functions: - heat the air in the ventilation, heating and air conditioning system; - cool the oil in the lubrication system; - cool the exhaust gases in the exhaust gas recirculation system; - cool the air in the turbo system. Most of the modern technology is equipped with a water cooling system, among which the advantages are an effective uniform cooling. In addition, the water cooling system has a low noise level. Cooling system design: - Volvo radiator; - Heater heat exchanger; - Oil radiator; - Expansion tank; - Thermostat; - Volvo water pump; - Volvo radiator fan; - Branch pipes; - Controls. The principle of the cooling system is as follows. Thanks to the liquid pump, the coolan →

Volvo turbocharger is a technically sophisticated mechanism that uses the kinetic energy of the exhaust gases to increase the pressure inside the Volvo intake system. Compressing, a mixture of fuel and air increases the mass of the fuel charge inside the Volvo cylinders, which increases the caloric content and, consequently, the engine power. The essence of the Volvo turbocharger is the strongest compression of air that enters the engine and enriches the fuel mixture, creating a high explosion power in the cylinder - this greatly improves the mass ratio of the Volvo engine to its power. Based on this, it can be argued that an engine with a Volvo turbocharger produces much more useful energy than the same unit without it. The operating speed of the Volvo turbine can be about 250,000 - 280,000 rpm. For comparison, the speed of the internal combustion engine itself is 30 times less. And since the Volvo turbocharger works by exhaust gases, the operating temperature of the supercharger i →

Air or fuel / air mixture enters the cylinders through the Volvo Construction intake manifold. The main purpose of the intake manifold is to ensure an even distribution of air or working mixture between the cylinders. This directly affects the efficiency of the Volvo engine. In addition, other nodes can be attached to the manifold. The principle of operation of the intake manifold of the Volvo engine is quite simple: air or its mixture with fuel, getting inside through the inlet, is divided into several streams, according to the number of cylinders of the engine. Pistons, moving downwards, create a vacuum in the collector, which can reach large values. This partial vacuum is also used to neutralize crankcase gases. They pass through the engine crankcase ventilation system into the Volvo intake manifold, mix with the fuel-air mixture or air and are burned in the cylinders. Until recently, the main material for the manufacture of the Volvo intake manifold of was aluminum, iron and  →
