The hydraulic pressure stands [The hydraulic pressure stands] The hydraulic station is also called
the hydraulic pump station. The motor drives the oil pump to rotate. The pump sucks oil from the oil pump and pumps oil to convert
mechanical energy into hydraulic oil. The pressure energy of the hydraulic oil is adjusted by the hydraulic valve through the
integrated block (or valve combination) to realize the direction, pressure, and flow adjustment, and then transmitted to the
hydraulic cylinder or oil motor through the external pipeline, thereby controlling the change of the direction of the hydraulic
motor. The size of the force and the speed of the speed push all kinds of hydraulic machinery to do work. It supplies oil
according to the requirements of the driving device (host), and controls the direction, pressure and flow of the oil flow. It is
suitable for various hydraulic machinery where the host and the hydraulic device are separable. After the user purchases, as long
as the hydraulic station is connected to the actuator (cylinder and oil motor) on the host with an oil pipe, the hydraulic machine
can realize various prescribed actions and working cycles. working principle The hydraulic station, also known as the hydraulic
pump station, is an independent hydraulic device. It supplies oil according to the requirements of the drive device (host) and
controls the direction, pressure and flow of the oil flow. It is suitable for various hydraulic machinery where the host and the
hydraulic device are separable. . The motor drives the oil pump to rotate. The pump sucks oil from the oil tank and then pumps
oil, which converts the mechanical energy into the pressure energy of the hydraulic oil. Components The hydraulic station is
composed of a pump device, integrated block or valve combination, oil tank, and electrical box. The functions of each component
are as follows: Pump device-equipped with a motor and an oil pump, it is the power source of the hydraulic station, which converts
the mechanical energy into the power energy of the hydraulic oil. Manifold-is a combination of hydraulic valve and channel body.
It regulates the direction, pressure and flow of hydraulic oil. Valve combination-is a plate type valve mounted on the vertical
plate, the pipe behind the plate is connected, and the function is the same as that of the manifold. The oil tank is a semi-closed
container welded with steel plate, and is also equipped with an oil filter, an air filter, etc., which are used for oil storage,
oil cooling and filtration. Electrical box-divided into two forms: one is equipped with a terminal board with external leads; the
other is equipped with a full set of control electrical appliances. Hydraulic system components ⑴Motor, gear pump-provide driving
force for hydraulic system. ⑵ Electromagnetic reversing valve-control the direction of hydraulic oil flow and change the direction
of movement of the oil cylinder. ⑶ Electromagnetic relief valve-prevent the entire hydraulic system from overpressure, equivalent
to a safety valve, protect the safety of the oil pump and the oil circuit system and keep the pressure of the hydraulic system
constant. ⑷ Pressure reducing valve-by adjusting the pressure reducing valve, different working mechanisms can meet the
requirements of different working pressures, so that the pressure of the secondary oil circuit is lower than the pressure of the
primary oil circuit. ⑸ Speed regulating valve-throttle and speed regulation of the oil circuit, which can change the working
speed of the hydraulic cylinder of the actuator. ⑹Hydraulic oil filter——There are two oil filter ports in the hydraulic station.
One is installed at the suction port of the gear pump to avoid sucking particles and other impurities in the hydraulic oil of the
oil tank. The other is installed on the hydraulic oil delivery pipeline of the system to remove impurities in the hydraulic oil,
and at the same time, it can also remove gums, asphaltenes, and carbonized particles produced by the chemical changes of the
hydraulic oil itself. So as to prevent the spool from jamming, the orifice clogging and other failures. The piping system is
equipped with a differential pressure alarm device. When the filter element is blocked, an electrical signal will be sent out. At
this time, the filter element should be cleaned or replaced. ⑺ Pressure gauge-used to display the working pressure of the
hydraulic station to facilitate the operator to control the oil pressure. ⑻Air filter-installed on the fuel tank, it has three
functions. One is to prevent pollutants in the air from entering the fuel tank; the other is to ventilate to prevent the pump from
emptying; and the third is to double as a hydraulic oil replenishment port. ⑼ Oil level gauge-installed on the side of the oil
tank to display the level of hydraulic oil. ⑽Temperature meter—Some oil tanks are equipped with a thermometer to display the
temperature of the hydraulic oil. ⑾ Connecting pipelines-conveying hydraulic driving force, mostly steel pipes, but also
pressure-resistant hoses. classification The structure of the hydraulic station is mainly distinguished by the structure of the
pump device, the installation position and the cooling method. 1. According to the mechanism and installation position of the pump
device, it can be divided into: 1) Top-mounted vertical type: The pump device is installed vertically on the fuel tank cover and
is mainly used for quantitative pump systems. 2) Top-mounted horizontal type: The pump device is installed horizontally on the
fuel tank cover, and is mainly used for variable pump systems to facilitate flow adjustment. 3) Side-mounted type: The pump device
is installed horizontally on a separate foundation next to the fuel tank. The side-mounted type can be equipped with a backup
pump. It is mainly used for systems with a large fuel tank capacity of 250 liters and a motor power of more than 7.5 kilowatts. 2.
According to the cooling method of the station, it can be divided into: 1) Natural cooling: Cooling by heat exchange between the
fuel tank itself and the air, generally used in systems with a fuel tank capacity of less than 250 liters. 2) Forced cooling: A
cooler is used for forced cooling, which is generally used for systems with a tank capacity greater than 250 liters. The hydraulic
station takes the effective oil storage measurement of the oil tank and the motor power as the main technical parameters. There
are 18 specifications of fuel tank capacity (unit: liter/L): 25, 40, 63, 100, 160, 250, 400, 630, 800, 1000, 1250, 1600, 2000,
2500, 3200, 4000, 5000, 6000 sets According to user requirements and operating conditions, the series of hydraulic stations can
achieve: ①Configure integrated blocks according to the system, or without integrated blocks; ②Can be equipped with coolers,
heaters, and accumulators; ③Can be equipped with electrical control devices, It is also possible to have no electrical control
device. 3. According to the fuel tank type, it can be divided into: 1) Ordinary steel plate: The box body is welded with 5MM-6MM
steel plate, and the panel is made of 10-12MM steel plate. If there are too many holes, it can be thickened or reinforced. 2)
Stainless steel plate: the box body is made of 304 stainless steel plate with a thickness of 2-3MM, the panel is made of 304
stainless steel plate with a thickness of 3-5MM, and the load-bearing part is increased with stiffeners. 3) It is difficult to
realize the anti-rust treatment inside the ordinary steel plate fuel tank. The rust entering the oil circulation system will cause
many failures. The fuel tank with all-stainless steel design solves this industry problem. 4. According to the structure of
commonly used hydraulic cylinders, it can be divided into: 1) Piston type The single-rod hydraulic cylinder has a piston rod at
only one end. As shown in the figure is a single-piston hydraulic cylinder. Both the inlet and outlet ports A and B at both ends
can pass pressure oil or return oil to achieve two-way movement, so it is called a double-acting cylinder. 2) Plunger type ① The
plunger hydraulic cylinder is a single-acting hydraulic cylinder, which can only achieve one direction of movement by hydraulic
pressure, and the return stroke of the plunger depends on other external forces or the weight of the plunger; ②The plunger is only
supported by the cylinder liner without contacting the cylinder liner, so that the cylinder liner is very easy to process, so it
is suitable for long-stroke hydraulic cylinders; ③The plunger is always under pressure during operation, so it must have
sufficient rigidity; ④The weight of the plunger is often large, and it is easy to sag due to its own weight when placed
horizontally, causing unilateral wear of the seal and the guide, so its vertical use is more advantageous. 3) Telescopic
Telescopic hydraulic cylinders have two-stage or multi-stage pistons. In the telescopic hydraulic cylinder, the order of extension
of the pistons is from large to small, while the order of no-load retraction is generally from small to large. The telescopic
cylinder can achieve a longer stroke, while the length is shorter when retracted, and the structure is more compact. Such
hydraulic cylinders are often used in construction machinery and agricultural machinery. 4) Swing type Swing hydraulic cylinder is
an executive element that outputs torque and realizes reciprocating motion, also known as swing hydraulic motor. There are two
forms of single blade and double blade. The stator block is fixed on the cylinder, and the blade and the rotor are connected
together. According to the oil inlet direction, the blade will drive the rotor to swing back and forth. The main parameters
Maximum working oil pressure=6.3MPa Maximum flow rate: "=9L/min Level 1 oil pressure value when braking in two [2] levels: 0~4MPa
adjustable for level 1 Working oil temperature: 15~60°C Oil tank storage capacity: 500L Secondary braking delay time: 110s
