Abstract
The utility model discloses a heating loop of a hydraulic lubricating system. The heating loop of the hydraulic lubricating system is characterized in that an oil tank is connected with an oil supply pipeline through a heating pump, and is provided with an outlet ball valve on a connection pipeline between the heating pump and the oil supply pipeline; an overflow pipeline communicated with the oil tank is further arranged on a pipeline between the heating pump and the outlet ball valve; and the overflow pipeline is provided with a pressure regulating valve, a throttling orifice and a laminar orifice sequentially in the direction from the heating pump to the oil tank. The heating loop of the hydraulic lubricating system disclosed by the utility model has the advantages of heating uniformly, preventing the surface of a heating element from scale depositing, thus being good for keeping oil clean, and avoiding the use of conventional heaters; therefore, the heating loop is rather fit for the fields where frequent heating is not needed; besides, the heating loop also has the advantages of simple structure, convenience in machining, and low total operational cost in that only the throttling orifice needs to be replaced in the case of heavy wear.
Description
Technical field
The utility model relates to a kind of heating circuit of oil pumping system.
Background technique
Hydraulic pressure, the lubrication system of metallurgy, mine or other industry equipment; Operating temperature to fluid has certain requirement usually; Often need to adopt heating equipment to control oily temperature and reach hydraulic pressure, the required temperature of lubrication station proper functioning, reduce oil viscosity, the resistance of fluid in the pipeline when reducing main working pump and starting; Thereby assurance hydraulic pressure, lubrication station work normally, and hydraulic pressure, lubricant oil are fed to each actuator and lubricating point.General commonly used mode of heating has in pipeline electric heater circulation heating, steam tube heating, the fuel tank electric heater heating is set.
1. pipeline electric heater circulation heating: shown in the accompanying drawing 1, comprising: heat pump 1, outlet valve 2, cartridge heater 3, tee ball valve 4, and composition such as pipeline fittings.
This kind mode of heating exists, the many complex structures of number of elements, and manufacture cost is high, the problem that floor space is big.
2. steam tube heating: as shown in Figure 2, the steam heater that temperature control valve (TCV) 5, butterfly valve 6, steam serpentine heating pipe 7, drain valve 8 and pipeline fittings are formed.
3. the electric heater heating is set in the fuel tank: as shown in Figure 3, the electric heater 9 in the fuel tank directly heats fluid.
The electric heater heating is set in steam tube heating heating and the fuel tank all belongs to the INSERTTYPE heating; The fluid local heating causes being heated inhomogeneous, and local temperature is too high, and it is rotten to be prone to cause that fluid quickens; Various heaters and steam tube surface are prone to adhere to the goo that rotten fluid forms simultaneously; Both be not easy cleaning, adsorbed other suspended matter again easily, be unfavorable for keeping the turbidity test of fuel tank.
Because there is above-mentioned shortcoming in traditional heating mode, so a kind of development of simplifying heating equipment is very important.
Summary of the invention
The utility model is directed against the proposition of above problem, and develops a kind of heating circuit of oil pumping system.The technological scheme that the utility model adopts is following:
A kind of heating circuit of oil pumping system is characterized in that: fuel tank is connected with oil supply line through behind the heat pump, and on the connecting pipeline between heat pump and the oil supply line, is provided with the outlet ball valve; Also be provided with the overflow passage that is connected with fuel tank on the pipeline between said heat pump and the outlet ball valve; On said overflow passage, be provided with pressure regulator valve, restricting orifice and laminar flow orifice plate successively to the fuel tank direction by heat pump.Can utilize and be circulated throughout working pump in filter pump or the lubrication system as heat pump in the hydraulic system.
The heating circuit that the utility model provides has overcome the shortcoming of above-mentioned traditional heating mode; Have homogeneous heating, the heating element surface is incrustation not, helps keeping oil cleanliness; Save the advantage of conventional heater, not needing to be highly suitable for the often environment of heating.In addition, this loop also has simple in structure, and is easy to process, and following of the situation of serious wear needs to change restricting orifice, thereby reaches loop overall operation advantage with low cost.
Description of drawings
Fig. 1 is the structural representation of conventional tube electric heater circulation mode of heating;
Fig. 2 is the structural representation of traditional steam tube heating;
Fig. 3 is for being provided with the structural representation of electric heater mode of heating in traditional fuel tank;
Fig. 4 is the structural representation of the said heating circuit of the utility model.
Embodiment
The heating circuit of oil pumping system as shown in Figure 4, wherein fuel tank is connected with oil supply line through heat pump 10 backs, and on the connecting pipeline between heat pump 10 and the oil supply line, is provided with outlet ball valve 14; Pipeline between said heat pump 10 and the outlet ball valve 14 is provided with the overflow passage that is connected with fuel tank; On said overflow passage, be provided with pressure regulator valve 11, restricting orifice 12 and laminar flow orifice plate 13 successively to the fuel tank direction by heat pump 10.
This loop is exported to through the heat pump in system pressure regulator valve, restricting orifice and a laminar flow orifice plate is installed on the overflow passage; The flow through pressure loss of pressure regulator valve, restricting orifice and laminar flow orifice plate of rational Match fluid; Make most of pressure loss on restricting orifice; The pressure loss of few part is on pressure regulator valve, and the pressure loss of laminar flow orifice plate is very little, and it mainly acts on is the bubble of the higher generation of oil flow velocity degree when eliminating heating; Make flowing of fluid become laminar flow and flow back to fuel tank by turbulent flow, simultaneously with the main oil feed line of pressure regulator valve loop parallel connection on a ball valve is installed before the filter.When fluid need heat, start heat pump after at first closing the ball valve on the main oil feed line, the fluid of pump discharge all flows back to fuel tank through pressure regulator valve, restricting orifice, laminar flow orifice plate.Because fluid all can produce the pressure loss when flowing through pressure regulator valve, restricting orifice and laminar flow orifice plate and produce heat, thus oil liquid temperature can raise, thereby realization is to the heating process of low temperature fluid.
Concrete implementation procedure is following: after at first will export ball valve 14 and closing, and startup heat pump 10.Fluid from the fuel tank sucking-off, all flows back to fuel tank through pressure regulator valve 11, restricting orifice 12 and laminar flow orifice plate 13 by heat pump 10, and the fluid said elements of flowing through produces the pressure loss and converts heat energy into, makes oily temperature rise.The effect of modulating valve is to guarantee that total overflow pressure drop is constant, and compensation oil temperature changes the restricting orifice and the laminar flow orifice plate pressure loss that cause and changes, thereby guarantees that heating power is constant.Let few partial pressure be lost on the pressure regulator valve during design, few pressure loss is at the laminar flow orifice plate.So not only can reduce the valve port wearing and tearing of pressure regulator valve 11, the performance of valve when guaranteeing the lubrication station proper functioning can also prolong working life of valve.
The above; Be merely the preferable embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or changes according to the technological scheme of the utility model and inventive concept thereof in the technical scope that the utility model discloses, and all should be encompassed within the protection domain of the utility model.
