Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0017] see figure 1 , a heat pump type oil heating unit, including a compressor 1, a condenser 2, an evaporator 3 and an oil pump 4, the compressor 1, the condenser 2 and the evaporator 3 are connected in series by setting pipelines and form a cycle , the oil pump 4 pumps the cold oil into the condenser 2, and then discharges it as hot oil. Two independent airtight passages are set in the condenser, one of which is connected with the compressor and the evaporator,...

Abstract

The invention discloses a heat-pump-type oil liquid heating unit, which comprises a compressor, a condenser, an evaporator and an oil pump. The compressor, the condenser and the evaporator are in series connection by arranging pipelines and form circulation, cold oil is pumped into the condenser by the oil pump and then discharged in a hot oil mode. The heat-pump-type oil liquid heating unit adopts independent airtight circulation, oil liquid is prevented from going bag and being polluted, compared with heating through an electric heating tube, the energy saving property is obvious, a whole cycle system operates reliably, and the oil liquid can be refrigerated when the oil temperature is overhigh.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a heat pump type oil heating unit. Background technique [0002] Hydraulic system, lubrication system in the case of low ambient temperature, in order to put the equipment into normal operation as soon as possible. The oil needs to be heated. At present, most heating methods use electric heating tubes for heating. Its disadvantages: 1. After the electric heating tube is immersed in the oil, it will cause carbonization and quality degradation to the surrounding oil. 2. The use of electric heating tubes consumes a lot of energy, and the service life is not long. Contents of the invention [0003] The object of the present invention is to provide a heat pump type oil heating unit aiming at the defects and deficiencies of the prior art. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a heat pump type oil heating u...
